django第一个app,7

经过admin页面更好的管理

分开显示：

polls/admin.py

from django.contrib import admin

from .models import Question


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

admin.site.register(Question, QuestionAdmin)

把一对多关联显示，这里额外显示3个

polls/admin.py

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)

choice列展现换位横向展现

class ChoiceInline(admin.TabularInline):

在数据列表里面展现更多的信息，字段和方法均可以

list_display = ('question_text', 'pub_date', 'was_published_recently')

点击字段名是自带排序的，除了方法，没有肯定的返回值，不能排序，咱们能够这样

定义某字段的排序值为别的值，

改变值为布尔值

改吗字段显示名称

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?'

添加一个筛选条件

list_filter = ['pub_date']

添加一个搜索条件，彷佛只能添加一个字符串的搜索条件

search_fields = ['question_text']

查找import包的路径，好比django

python -c "import django; print(django.__path__)"

设定项目本身的templates

mysite/settings.py

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        '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',
            ],
        },
    },
]

在manage.py同目录下建立templates/admin。复制django自带的目录下的base_site.html复制到admin文件下，改变内容

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

项目会自动覆盖原django的文件，而展现这个文件内容，通常最重要的是admin下的index.html，也能够像这样覆盖。
