Tutorial_7：Customizing the admin

一、管理admin

1、修改顺序

from django.contrib import admin
from .models import Question

class QuestionAdmin(admin.ModelAdmin):
    fields = ['pub_date', 'question_text']

admin.site.register(Question, QuestionAdmin)

使得pub_date显示在question_text前面。

2、修改标题

class QuestionAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question_text']}),
        ('Date information', {'fields': ['pub_date']}),
    ]

使得显示的标题信息增加。

3、增加投票信息

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

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

class QuestionAdmin(admin.ModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question_text']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [ChoiceInline]

admin.site.register(Question, QuestionAdmin)

使用内联式的会更好。

class ChoiceInline(admin.TabularInline):
    #...

4、列表信息

class QuestionAdmin(admin.ModelAdmin):
    # ...
    list_display = ('question_text', 'pub_date', 'was_published_recently')

5、添加filter

models里添加。

class Question(models.Model):
    # ...
    def was_published_recently(self):
        now = timezone.now()
        return now - datetime.timedelta(days=1) <= self.pub_date <= now
    was_published_recently.admin_order_field = 'pub_date'
    was_published_recently.boolean = True
    was_published_recently.short_description = 'Published recently?'

admin里的QuestionAdmin添加。

list_filter = ['pub_date']

6、添加搜索

admin里的QuestionAdmin添加。

search_fields = ['question_text']

二、建立app的admin

在app的templates文件夹下建立admin文件夹，将django/contrib/admin/templates/admin/base_site.html拷贝到templates/admin/下。
修改指定部分

{% block branding %}
<h1 id="site-name"><a href="{% url 'admin:index' %}">Polls Administration</a></h1>
{% endblock %}
