您正在寻找ModelAdmin.list_filter。
设置list_filter以激活管理员更改列表页面右侧栏中的过滤器。listfilter可以是字段名称,其中指定的字段应该是BooleanField,CharField,DateField,DateTimeField,IntegerField,ForeignKey或ManyToManyField,例如:
# Add a list filter author to BookAdmin. # Now you can filter books by author. class BookAdmin(ModelAdmin): list_filter = ('author', )现在,您可以使用@Wolph建议在作者list_display中添加链接。该链接指向按作者过滤的图书清单:
# Add hyperlinks to AuthorAdmin.# Now you can jump to the book list filtered by autor. class AuthorAdmin(admin.ModelAdmin): def authors(self): return '<a href="/admin/appname/book/?author__id__exact=%d">%s</a>' % (self.author_id, self.author) authors.allow_tags = True
替代。要保存点击,您还可以直接指向书籍的更改视图:
class Books(models.Model): title = models.CharField() author = models.ForeignKey(Author)def get_admin_url(self): return "/admin/appname/books/%d/" %self.idclass BookAdmin(admin.ModelAdmin): def authors(self): html = "" for obj in Books.objects.filter(author__id_exact=self.id): html += '<p><a href="%s">%s</a></p>' %(obj.get_admin_url(), obj.title) return html authors.allow_tags = True list_display = ['title', authors]
免责声明:未经测试,但是如果您解决了错字问题,它将起作用!:)
请注意,这些链接也可以在管理员的其他位置插入。将其添加到窗口小部件时,可以从更改视图转到更改视图。
