Django CustomUser model Image field display in User List

问题

UserProfile 是一个 CustomUser 模型，拥有 avatar、bio 和 display 字段。

我想在用户列表中显示个人资料的头像。

我已经添加了一个名为 avatar_tag 的函数，供用户列表调用。

  1. #models.py
  2. class UserProfile(models.Model):
  3.     
  4.     user   = models.OneToOneField(User,on_delete=models.CASCADE)
  5.     
  6.     
  7.     def get_upload_avatar_to(self, filename):
  8.         return f"images/avatar/{self.user.id}/{filename}"
  9.     avatar = models.ImageField(upload_to=get_upload_avatar_to, null=True, blank=True)
  11.     def avatar_tag(self):
  12.         if self.avatar.url is not None:
  13.             return mark_safe('<img src="{}" height="50"/>'.format(self.avatar.url))
  14.         else:
  15.             return ""
  16.     avatar_tag.short_description = 'Image'
  17.     avatar_tag.allow_tags = True
  18.     full_name = ''
  19.    
  20.     bio    = models.TextField(default="", blank=True)
  21.     display    = models.CharField(default=full_name,max_length=512,blank=True)

在 admin.py 中的代码如下：

  1. class UserProfileInline(admin.StackedInline):
  2.     model = UserProfile
  3.     fk_name = 'user'
  4.     can_delete = False
  5.     verbose_name = "User profile"
  6.     verbose_name_plural = 'Profiles'
  7.     classes = ('text-capitalize','collapse open')
  8.     extra = 1
  9.     list_display = ('avatar_tag',)
  10.     fieldsets =  (
  11.         ("Profile", {'fields': ('avatar','bio','display',)}),)
  14. class UserProfileAdmin(UserAdmin):
  15.     inlines = (UserProfileInline,)

如何在用户表的列表视图中显示头像图片？

在用户列表中没有看到头像，但没有报错。

这是图片

UserProfile is CustomUser Model having columns avatar, bio and display fields.

I want to show Profile avatar in the User List

I have added avatar_tag function to be called by the users list

  1. #models.py
  2. class UserProfile(models.Model):
  3.     
  4.     user   = models.OneToOneField(User,on_delete=models.CASCADE)
  5.     
  6.     
  7.     def get_upload_avatar_to(self, filename):
  8.         return f&quot;images/avatar/{self.user.id}/{filename}&quot;
  9.     avatar = models.ImageField(upload_to=get_upload_avatar_to, null=True, blank=True)
  11.     def avatar_tag(self):
  12.         if self.avatar.url is not None:
  13.             return mark_safe(&#39;&lt;img src=&quot;{}&quot; height=&quot;50&quot;/&gt;&#39;.format(self.avatar.url))
  14.         else:
  15.             return &quot;&quot;
  16.     avatar_tag.short_description = &#39;Image&#39;
  17.     avatar_tag.allow_tags = True
  18.     full_name = &#39;&#39;
  19.    
  20.     bio    = models.TextField(default=&quot;&quot;, blank=True)
  21.     display    = models.CharField(default=full_name,max_length=512,blank=True)

admin.py code is below

  1. class UserProfileInline(admin.StackedInline):
  2.     model = UserProfile
  3.     fk_name = &#39;user&#39;
  4.     can_delete = False
  5.     verbose_name = &quot;User profile&quot;
  6.     verbose_name_plural = &#39;Profiles&#39;
  7.     classes = (&#39;text-capitalize&#39;,&#39;collapse open&#39;)
  8.     extra = 1
  9.     list_display = (&#39;avatar_tag&#39;)
  10.     fieldsets =  (
  11.         (&quot;Profile&quot;, {&#39;fields&#39;: (&#39;avatar&#39;,&#39;bio&#39;, &#39;display&#39;,)}),)
  14. class UserProfileAdmin(UserAdmin):
  15.     inlines = (UserProfileInline,)

How can I show the avatar image in list view of the User table?

I am not getting any errors in the user list avatar is not shown

Here is the image

得分: 1

  1. 从django.utils.html导入format_html
  3. class UserProfileAdmin(UserAdmin):
  4.     list_display = ("avatar_tag",) # 如果你想要的话，可以传递其他字段，比如姓名
  6.     def avatar_tag(self, obj):
  7.         if obj.userprofile.avatar:
  8.             return format_html(
  9.                 '<img src="%s"/>' % obj.userprofile.avatar.url
  10.             )
  11.         return "无头像"
英文:

Try this code

  1. from django.utils.html import format_html
  4. class UserProfileAdmin(UserAdmin):
  5.     list_display = (&quot;avatar_tag&quot;,) # pass other fileds if you want eg. name
  7.     def avatar_tag(self, obj):
  8.         if obj.userprofile.avatar:
  9.             return format_html(
  10.                 &#39;&lt;img src=&quot;%s&quot;/&gt;&#39; % obj.userprofile.avatar.url
  11.             )
  12.         return &quot;No avatar&quot;

list_display accepts callable argument so you can pass custom method names in it.
