Django 应用开发（2）

1.创建一个管理员用户

创建一个用于登录管理站点的用户

2.启动开发服务器

python manage.py runserver

打开浏览器访问本地域名中的/admin/

3.让poll应用在管理站点中可编辑

在polls/admin.py中编辑

4.修改界面

在polls/admin.py中编辑

from django.contrib import admin
from .models import Choice,Question

class ChoiceInline(admin.TabularInline):
    model = Choice
    extra = 3

class QuestionAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,{'fields':['question']}),
        ('Date information',{'fields':['pub_date'],'classes':['collapse']})
    ]
    inlines = [ChoiceInline]
admin.site.register(Question,QuestionAdmin)
# Register your models here.

自定义管理界面中的变更列表

admin.py

from django.contrib import admin
from .models import Choice,Question

class ChoiceInline(admin.TabularInline):
    model = Choice
    extra = 3

class QuestionAdmin(admin.ModelAdmin):
    list_display = ('question','pub_date','was_published_recently')
    fieldsets = [
        (None,{'fields':['question']}),
        ('Date information',{'fields':['pub_date'],'classes':['collapse']})
    ]
    inlines = [ChoiceInline]
    list_filter = ['pub_date'] 
    search_fields = ['question']
    
admin.site.register(Question,QuestionAdmin)
# Register your models here.

models.py

from __future__ import unicode_literals

import datetime
from django.db import models
from django.utils import timezone


class Question(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    
    def __str__(self):
        return self.question
        
    def  was_published_recently(self):
        return self.pub_date >=timezone.now() - datetime.timedelta(days=1)
    
    was_published_recently.admin_order_field = 'pub_date'
    was_published_recently.boolean = True
    was_published_recently.short_description = 'Published recently?'

    
class Choice(models.Model):
    poll  = models.ForeignKey(Question)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)
    
    def  __str__(self):
        return self.choice_text

# Create your models here.

自定义站点的外观

在templates中添加dirs选项

创建templates文件夹

在settings.py中添加。现在，在templates下创建一个名为admin的文件夹，然后从Django安装的原目录下（目录为django/contrib/admin/templates）将模板页面的源文件admin/base_site.html拷贝到这个文件夹里。并修改其中的html文件。

 结果：
