自定义KingAdmin

通过admin样式自己做KingAdmin

提前需知道的model操作

# 获取app名
>>> models.Customer._meta.app_label
'repository'# 获取数据表名
>>> models.Customer._meta.verbose_name # verbose_name
'customer'
>>> models.Customer._meta.verbose_name_plural
'客户表'
>>> models.Customer._meta.model_name #表名小写
'customer' # 获取数据表字段、是否为choices类型
>>> models.Customer._meta.get_field('status')
<django.db.models.fields.SmallIntegerField: status> #字段
>>> models.Customer._meta.get_field('status').choices #choices字段
((0, '已报名'), (1, '未报名'), (2, '已退学'), (3, '其他'))
>>> models.Customer._meta.get_field('id').choices # 普通字段
[]
>>> models.Customer._meta.get_field('consultant').choices #外键字段
[]

1、在Django项目中创建kingadmin

2、app_config.py获取已注册以及存在kingadmin.py的App

from django import conffor app in conf.settings.INSTALLED_APPS:
try:
__import__('%s.kingadmin'%app)
except ImportError as e:
print('%s has no model kingadmin'%app)

3、views.py加载自定义的app_config.py文件

4、base_admin.py定义注册的model（核心）

class AdminRegisterException(Exception):
def __init__(self,msg):
self.message = msgclass BaseAdmin(object):
list_display = ()
list_filter = ()
search_fields = ()
list_editable = ()class Adminsite(object):
def __init__(self):
self.registered_sites = {} def register(self,model,admin_class=None):
'''
:param model: <class 'crm.models.Course'>
:param admin_class:
:return:
'''
app_name = model._meta.app_label # python manage.py shell
model_name = model._meta.model_name # dir(<class 'crm.models.Course'>) 查看具有的方法
if not admin_class:
admin_class = BaseAdmin if app_name not in self.registered_sites:
self.registered_sites[app_name]={} if model_name in self.registered_sites[app_name]:
raise AdminRegisterException("app [%s] model [%s] has already registered!" % (app_name, model_name)) # admin_obj = admin_class()
admin_obj = admin_class()
admin_obj.model = model
self.registered_sites[app_name][model_name] = admin_objsite = Adminsite()# site = {
# 'crm':{
# 'customers':CustomerAdmin,
# 'customerfollowup':CustomerFollowUPAdmin,
# }
# }

5、crm目录下创建kingadmin.py进行models注册

from kingadmin.base_admin import site,BaseAdmin
from crm import modelsclass CustomerAdmin(BaseAdmin):
list_display = ('id','name','qq','consultant','source','consult_content','status','data')
list_filter = ('source','status','consultant')
search_fields = ('qq','name')
list_editable = ('status',)site.register(models.Customer,CustomerAdmin)
site.register(models.FollowUpRecord)
site.register(models.Enrollment)

from django.db import models
from django.contrib.auth.models import User
# Create your models here.class Customer(models.Model):

referral_from = models.ForeignKey('Customer',related_name='my_referrals',blank=True,null=True) # 自关联，字段可写slef，必须写related_name
consult_courses = models.ManyToManyField(to='Course')
status_choices = (

)
status = models.SmallIntegerField(choices=status_choices)

class_type_choices = ((0,'脱产'),(1,'周末'),(2,'网络'))
branch = models.ForeignKey("Branch")
class_type = models.PositiveIntegerField(choices=class_type_choices)
teachers = models.ManyToManyField(to='UserProfile')

return " daynum:%s" % (self.day_number)class StudyRecord(models.Model):
'''每个学生上的每节课的成绩记录'''
course_record = models.ForeignKey("CourseRecord")

url_name = models.CharField(unique=True,max_length=128) class Meta:
verbose_name_plural = '菜单表' def __str__(self):
return self.name

model.py

6、kingadmin目录下创建templates/kingadmin页面目录

设置settings文件：

TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates'),
os.path.join(BASE_DIR, 'kingadmin','templates'),] #加入环境变量
,
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]

7、创建templatetags目录下kingadmin_tags.py文件自定义模板方法

from django import template
from django.utils.safestring import mark_saferegister = template.Library()@register.simple_tag
def get_model_verbose_name(model_obj): model_name = model_obj._meta.verbose_name_plural if not model_name:
model_name = model_obj._meta.model_name return model_name@register.simple_tag
def get_model_name(model_obj): return model_obj._meta.model_name@register.simple_tag
def get_app_name(model_obj): return model_obj._meta.app_label@register.simple_tag
def build_table_row(admin_obj,obj): row_ele = "" for column in admin_obj.list_display:
column_obj = obj._meta.get_field(column)
if column_obj.choices:
get_column_data = getattr(obj,"get_%s_display" % column)
column_data = get_column_data()
else:
column_data = getattr(obj, column) td_ele = '''<td>%s</td>''' % column_data
row_ele += td_ele return mark_safe(row_ele)

初步效果：

模仿Admin做检索

1、修改views.py

from django.shortcuts import renderfrom kingadmin import app_config # 加载app_config
from kingadmin.base_admin import sitedef app_index(request): print(id(site),site.registered_sites)
return render(request, 'kingadmin/app_index.html',{'site':site})def filter_querysets(request,model): #过滤
condtions = {}
for k,v in request.GET.items():
if v :
condtions[k] = v
querysets =model.objects.filter(**condtions) return querysets,condtionsdef table_data_list(request,app_name,model_name): #重新改造函数，加上过滤条件
# print(request.GET)
admin_obj = site.registered_sites[app_name][model_name]
model = admin_obj.model
admin_obj.querysets,admin_obj.condtions = filter_querysets(request,model) print(admin_obj.condtions)
return render(request,"kingadmin/table_data_list.html",locals()) # locals 传入局部变量

2、新增自定义simple_tag

@register.simple_tag
def get_filter_field(filter_column,admin_obj):
field_obj = admin_obj.model._meta.get_field(filter_column) selected = None
condtions = admin_obj.condtions
if filter_column in condtions:
selected = condtions[filter_column] select_ele = """<select name= "%s">""" % filter_column
for choice in field_obj.get_choices():
if selected and selected == str(choice[0]):
option_ele = """<option value="%s" selected> %s </option> """ % choice
else:
option_ele = """<option value="%s"> %s </option> """%choice
select_ele +=option_ele
select_ele += """</select>""" return mark_safe(select_ele)

3、修改table_data_list.html

{% extends 'kingadmin/index.html' %}
{% load kingadmin_tags %}{% block right-container-content %} <h4>{% get_model_verbose_name admin_obj.model %}</h4>
{# {{ admin_obj.list_filter }}#}
{% if admin_obj.list_filter %}
<div class="row">
<form>
{% for filter_column in admin_obj.list_filter %}
<div class="col-lg-3">
{{ filter_column }}:{% get_filter_field filter_column admin_obj %}
</div>
{% endfor %}
<input type="submit" class="btn btn-success" value="过滤">
</form>
</div>
{% endif %}
<table class="table table-hover">
<thead>
<tr>
{% for column in admin_obj.list_display %}
<th>{{ column }}</th>
{% endfor %}
</tr>
</thead>
<tbody> {% for obj in admin_obj.querysets %}
<tr>
{% build_table_row admin_obj obj %} </tr>
{% endfor %}
</tbody>
</table>{% endblock %}

利用Django自带分页

1、Paginantor官方源码示例-》跳转

>>> from django.core.paginator import Paginator
>>> objects = ['john', 'paul', 'george', 'ringo']
>>> p = Paginator(objects, 2)>>> p.count
4
>>> p.num_pages
2
>>> type(p.page_range) # `<type 'rangeiterator'>` in Python 2.
<class 'range_iterator'>
>>> p.page_range
range(1, 3)>>> page1 = p.page(1)
>>> page1
<Page 1 of 2>
>>> page1.object_list
['john', 'paul']>>> page2 = p.page(2)
>>> page2.object_list
['george', 'ringo']
>>> page2.has_next()
False
>>> page2.has_previous()
True
>>> page2.has_other_pages()
True
>>> page2.next_page_number()
Traceback (most recent call last):
...
EmptyPage: That page contains no results
>>> page2.previous_page_number()
1
>>> page2.start_index() # The 1-based index of the first item on this page
3
>>> page2.end_index() # The 1-based index of the last item on this page
4>>> p.page(0)
Traceback (most recent call last):
...
EmptyPage: That page number is less than 1
>>> p.page(3)
Traceback (most recent call last):
...
EmptyPage: That page contains no results

基本使用方法

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
from django.shortcuts import renderdef listing(request):
contact_list = Contacts.objects.all()
paginator = Paginator(contact_list, 25) # Show 25 contacts per page page = request.GET.get('page')
try:
contacts = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
contacts = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
contacts = paginator.page(paginator.num_pages) return render(request, 'list.html', {'contacts': contacts})

后端处理

{% for contact in contacts %}
{# Each "contact" is a Contact model object. #}
{{ contact.full_name|upper }}<br />
...
{% endfor %}<div class="pagination">
<span class="step-links">
{% if contacts.has_previous %}
<a href="?page={{ contacts.previous_page_number }}">previous</a>
{% endif %} <span class="current">
Page {{ contacts.number }} of {{ contacts.paginator.num_pages }}.
</span> {% if contacts.has_next %}
<a href="?page={{ contacts.next_page_number }}">next</a>
{% endif %}
</span>
</div>

前端展示

2、添加分页全局变量kingadmin.py

3、处理函数views.py

def filter_querysets(request,model): #过滤
condtions = {}
for k,v in request.GET.items():
if v and k !='page':
condtions[k] = v
querysets =model.objects.filter(**condtions) return querysets,condtionsfrom django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
from django.shortcuts import renderdef listing(request,admin_obj): paginator = Paginator(admin_obj.querysets, admin_obj.list_per_page) # Show 25 contacts per page
page = request.GET.get('page')
try:
contacts = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
contacts = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
contacts = paginator.page(paginator.num_pages) return contactsdef table_data_list(request,app_name,model_name): #重新改造函数，加上过滤条件
# print(request.GET)
admin_obj = site.registered_sites[app_name][model_name]
model = admin_obj.model
admin_obj.querysets,admin_obj.condtions = filter_querysets(request,model)
print('before',admin_obj.querysets)
admin_obj.querysets = listing(request,admin_obj)
print('after',admin_obj.querysets) return render(request,"kingadmin/table_data_list.html",locals()) # locals 传入局部变量

4、kingadmin_tags.py

@register.simple_tag()
def generate_filter_url(admin_obj):
url = ""
for k,v in admin_obj.condtions.items():
url += "&%s=%s"%(k,v) return url

5、table_data_list.html

tfoot>
<nav aria-label="...">
<ul class="pagination">
<li class="disabled"><a href="#" aria-label="Previous"><span aria-hidden="true">«</span></a></li>
{% for page in admin_obj.querysets.paginator.page_range %}
{% if page == admin_obj.querysets.number %}
<li class="active">
{% else %}
<li >
{% endif %}
<a href="?page={{ page }}{% generate_filter_url admin_obj %}">{{ page }} <span class="sr-only">(current)</span></a>
</li>
{% endfor %}
</ul>
</nav>
</tfoot>

显示效果：

过滤、排序、分页组合

1、在原views.py上新增：

# 添加排序
def get_orderby(request,querysets): #排序
orderby_fieid = request.GET.get('o')
if orderby_fieid:
querys_res = querysets.order_by(orderby_fieid)
else:
querys_res = querysets return querys_res# 过滤修改
def filter_querysets(request,model): #过滤
condtions = {}
except_list = ["page",'o']
for k,v in request.GET.items():
if k in except_list:continue
if v:
condtions[k] = v
querysets =model.objects.filter(**condtions) return querysets,condtions# 分页添加
def listing(request,admin_obj):
querys_res = get_orderby(request, admin_obj.querysets)

2、自定义simple_tag

@register.simple_tag()
def generate_filter_url(admin_obj,request=None):
url = ""
if request:
if request.GET.get('o'):
url += "&o=%s" % request.GET.get('o')
for k,v in admin_obj.condtions.items():
url += "&%s=%s"%(k,v) return url@register.simple_tag
def get_orderby_key(request,column):
current_order_by_key = request.GET.get('o')
if current_order_by_key:
if current_order_by_key == column:
if column.startswith('-'):
column.strip("-")
else:
column = "-%s"%column
return column
else:
return column@register.simple_tag
def display_order_by_icon(request,column):
current_order_by_key = request.GET.get('o')
if current_order_by_key:
if current_order_by_key.strip('-') == column:
if current_order_by_key.startswith('-'):
icons = '''<span class="glyphicon glyphicon-arrow-up" aria-hidden="true"></span>'''
else:
icons = '''<span class="glyphicon glyphicon-arrow-down" aria-hidden="true"></span>''' return mark_safe(icons) return ' '

3、html前端页面

// 过滤时添加排序
<form>
{% for filter_column in admin_obj.list_filter %}
<div class="col-lg-3">
{{ filter_column }}:{% get_filter_field filter_column admin_obj %}
</div>
{% endfor %}
<input type="submit" class="btn btn-success" value="过滤">
<input type="hidden" name="o" value="{{ request.GET.o }}"> //过滤时加上排序

点击过滤或排序时页面恢复到第一页

搜索

1、views.py处理文件

# 添加搜索函数注意顺序def get_search(request,admin_obj):
search_content = request.GET.get('q')
condition = Q()
condition.connector = 'OR'
if search_content:
for column in admin_obj.search_fields:
condition.children.append(("%s__contains"%column,search_content)) querysets = admin_obj.querysets.filter(condition)
else:
querysets = admin_obj.querysets
return querysetsdef table_data_list(request,app_name,model_name): #重新改造函数，加上过滤条件 admin_obj = site.registered_sites[app_name][model_name]
model = admin_obj.model admin_obj.querysets,admin_obj.condtions = filter_querysets(request,model) #加过滤条件 admin_obj.querysets = get_search(request,admin_obj) # 搜索 admin_obj.querysets = listing(request,admin_obj) #分页 return render(request,"kingadmin/table_data_list.html",locals()) # locals 传入局部变量

2、自定义simple_tag

@register.simple_tag()
def generate_filter_search(request):
search_content = request.GET.get('q')
url = ""
if search_content:
url = "&q=%s"%search_content return url

3、前端html页面

过滤时的from
<form>
{% for filter_column in admin_obj.list_filter %}
<div class="col-lg-3">
{{ filter_column }}:{% get_filter_field filter_column admin_obj %}
</div>
{% endfor %}
<input type="submit" class="btn btn-success" value="过滤">
{# //过滤时加上排序#}
<input type="hidden" name="o" value="{{ request.GET.o }}">
<br/>
<input type="text" name="q" value="{{ request.GET.q }}">
</form>排序
{% for column in admin_obj.list_display %}
<th>
{# // 排序时加上过滤#}
<a href="?o={% get_orderby_key request column %}{% generate_filter_search request %}{% generate_filter_url admin_obj %}"> {{ column }}</a>
{% display_order_by_icon request column %}
</th>
{% endfor %}分页
<a href="?page={{ page }}{% generate_filter_search request %}{% generate_filter_url admin_obj request%}">{{ page }} <span class="sr-only">(current)</span></a>

页面显示：

数据修改

1、kingadmin下创建forms.py

from django import formsdef CreateModelForm(admin_obj): # 动态生成modelfrom
class Meta:
model = admin_obj.model
fields = "__all__" dynamic_model_form = type("DynamicModelForm",(forms.ModelForm,),{'Meta':Meta}) return dynamic_model_form

2、views.py处理函数

3、html文件

{% extends "kingadmin/index.html" %}{% load kingadmin_tags %}{% block right-container-content %}
{{ obj_form }}
{% endblock %}

table_change.html

显示视图：

修改完善

1、html文件

{% extends "kingadmin/index.html" %}{% load kingadmin_tags %}{% block right-container-content %}
<div class="row" style="margin-bottom: 20px" >
<ol class="breadcrumb">
<li><a href="/kingadmin/">Home</a></li>
<li><a href="/kingadmin/{% get_app_name admin_obj.model %}/">{% get_app_name admin_obj.model %}</a></li>
<li ><a href="/kingadmin/{% get_app_name admin_obj.model %}/{% get_model_name admin_obj.model %}/">{% get_model_verbose_name admin_obj.model%} </a></li>
<li class="active">{{ obj_form.instance }}</li>
</ol> <h4>Change {% get_model_verbose_name admin_obj.model %}</h4>
</div> <form class="form-horizontal" method="post" onsubmit="return BeforeFormSubmit(this);">{% csrf_token %}
{% for field in obj_form %}
<div class="form-group">
<label class="col-sm-2 " style="font-weight: normal">
{% if field.field.required %}
<b>{{ field.label }}</b>
{% else %}
{{ field.label }}
{% endif %}
</label>
<div class="col-sm-10">
<span style="color: red;">{{ field.errors }}</span>
{{ field }}
</div>
</div>
{% endfor %}
<input type="submit" value="Save" class="pull-right btn btn-info" >
</form>
{% endblock %}

table_data_list.html

2、froms.py

3、views.py处理文件

from kingadmin import forms
def table_change(request,app_name,model_name,id):
admin_obj = site.registered_sites[app_name][model_name]
obj = admin_obj.model.objects.filter(id=id).first()
model_form = forms.CreateModelForm(admin_obj) if request.method == "GET":
obj_form = model_form(instance=obj)
elif request.method == "POST":
obj_form = model_form(instance=obj, data=request.POST)
if obj_form.is_valid():
obj_form.save() return render(request, "kingadmin/table_change.html", locals())

表单添加

1、html文件

{% extends "kingadmin/index.html" %}{% load kingadmin_tags %}{% block right-container-content %}
<div class="row" style="margin-bottom: 20px" >
<ol class="breadcrumb">
<li><a href="/kingadmin/">Home</a></li>
<li><a href="/kingadmin/{% get_app_name admin_obj.model %}/">{% get_app_name admin_obj.model %}</a></li>
<li ><a href="/kingadmin/{% get_app_name admin_obj.model %}/{% get_model_name admin_obj.model %}/">{% get_model_verbose_name admin_obj.model%} </a></li>
<li class="active">Add {% get_model_name admin_obj.model %}</li>
</ol> <h4>Change {% get_model_verbose_name admin_obj.model %}</h4>
</div> <form class="form-horizontal" method="post" onsubmit="return BeforeFormSubmit(this);">{% csrf_token %}
{% for field in obj_form %}
<div class="form-group">
<label class="col-sm-2 " style="font-weight: normal">
{% if field.field.required %}
<b>{{ field.label }}</b>
{% else %}
{{ field.label }}
{% endif %}
</label>
<div class="col-sm-10">
<span style="color: red;">{{ field.errors }}</span>
{{ field }}
</div>
</div>
{% endfor %}
<input type="submit" value="Save" class="pull-right btn btn-info" >
</form>
{% endblock %}

table_add.html

2、froms.py文件

3、views.py处理文件

def table_add(request,app_name,model_name):
admin_obj = site.registered_sites[app_name][model_name]
model_form = forms.CreateModelForm(admin_obj)
if request.method == "GET":
obj_form = model_form() if request.method == "POST":
obj_form = model_form(data=request.POST)
if obj_form.is_valid():
obj_form.save()
if not obj_form.errors:
return redirect('/kingadmin/%s/%s'%(app_name,model_name)) return render(request, "kingadmin/table_add.html", locals())

增加readonly_fields字段

1、forms.py文件修改

from django import formsdef CreateModelForm(admin_obj): # 动态生成modelfrom
class Meta:
model = admin_obj.model
fields = "__all__" def __new__(cls, *args, **kwargs):
# print("base fields",cls.base_fields)
for field_name, field_obj in cls.base_fields.items():
# print(field_name,dir(field_obj))
field_obj.widget.attrs['class'] = 'form-control'
# field_obj.widget.attrs['maxlength'] = getattr(field_obj,'max_length' ) if hasattr(field_obj,'max_length') \
# else ""
if field_name in admin_obj.readonly_fields:
field_obj.widget.attrs['disabled'] = True return forms.ModelForm.__new__(cls) def default_clean(self):
# print("default clean:",self)
for field in admin_obj.readonly_fields:
print("readonly", field, self.instance)
field_val_from_db = getattr(self.instance, field)
field_val = self.cleaned_data.get(field)
if field_val_from_db == field_val:
print("field not change ")
else: # 被篡改了
self.add_error(field, ' "%s" is a readonly field ,value should be "%s" ' % (field, field_val_from_db)) print("cleaned data:", self.cleaned_data) dynamic_model_form = type("DynamicModelForm",(forms.ModelForm,),{'Meta':Meta})
setattr(dynamic_model_form,"__new__",__new__)
setattr(dynamic_model_form,"clean",default_clean)
return dynamic_model_form

添加action动作

1、kingadmin.py

class CustomerAdmin(BaseAdmin):
list_display = ('id','name','qq','consultant','source','consult_content','status','data')
list_filter = ('source','status','consultant')
search_fields = ('qq','name')
list_editable = ('status',)
readonly_fields = ('name',)
list_per_page = 5
actions = ["change_status", ] def change_status(self, request, querysets):
print("changeing status", querysets)
querysets.update(status=1) change_status.short_description = "改变报名状态"class EnrollmentAdmin(BaseAdmin):
list_display = ('customer','class_grade','enrollment_date')site.register(models.Customer,CustomerAdmin)
site.register(models.FollowUpRecord)
site.register(models.Enrollment,EnrollmentAdmin)

2、views.py处理函数

def table_data_list(request,app_name,model_name): #重新改造函数，加上过滤条件
admin_obj = site.registered_sites[app_name][model_name] if request.method == "POST": action = request.POST.get("action_select")
selected_ids = request.POST.get("selected_ids")
selected_ids = json.loads(selected_ids)
print("action:",selected_ids,action)
selected_objs = admin_obj.model.objects.filter(id__in=selected_ids) action_func = getattr(admin_obj,action)
action_func(request,selected_objs) model = admin_obj.model admin_obj.querysets,admin_obj.condtions = filter_querysets(request,model) #加过滤条件 admin_obj.querysets = get_search(request,admin_obj) # 搜索 admin_obj.querysets = listing(request,admin_obj) #分页 return render(request,"kingadmin/table_data_list.html",locals()) # locals 传入局部变量

3、table_data_list.html

{% extends 'kingadmin/index.html' %}
{% load kingadmin_tags %}{% block right-container-content %}
