Django CustomUser model Image field display in User List

Question

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

#models.py
class UserProfile(models.Model):
    
    user   = models.OneToOneField(User,on_delete=models.CASCADE)
    
    
    def get_upload_avatar_to(self, filename):
        return f"images/avatar/{self.user.id}/{filename}"
    avatar = models.ImageField(upload_to=get_upload_avatar_to, null=True, blank=True)

    def avatar_tag(self):
        if self.avatar.url is not None:
            return mark_safe('<img src="{}" height="50"/>'.format(self.avatar.url))
        else:
            return ""
    avatar_tag.short_description = 'Image'
    avatar_tag.allow_tags = True
    full_name = ''
   
    bio    = models.TextField(default="", blank=True)
    display    = models.CharField(default=full_name,max_length=512,blank=True)

admin.py code is below

class UserProfileInline(admin.StackedInline):
    model = UserProfile
    fk_name = 'user'
    can_delete = False
    verbose_name = "User profile"
    verbose_name_plural = 'Profiles'
    classes = ('text-capitalize','collapse open')
    extra = 1
    list_display = ('avatar_tag')
    fieldsets =  (
        ("Profile", {'fields': ('avatar','bio', 'display',)}),)


class UserProfileAdmin(UserAdmin):
    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

Try this code

from django.utils.html import format_html


class UserProfileAdmin(UserAdmin):
    list_display = ("avatar_tag",) # pass other fileds if you want eg. name

    def avatar_tag(self, obj):
        if obj.userprofile.avatar:
            return format_html(
                '<img src="%s"/>' % obj.userprofile.avatar.url
            )
        return "No avatar"

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