At the moment I'm working on an e-commerce application.

It contains a sub-app called "blog". The idea is that the superuser creates an account for the *Trainer. And yeah, I already created a new AbstractUser

Trainer logins into his account and creates Post I logged in here using my Trainer`s credentials

After I want the superuser to see WHO created post, but DjangoAdmin displays me admin`s email

How could I display the email of the 'creator' of the post in Django admin?

Code:

#models.py
class UserTrainer(AbstractUser):
    email = models.EmailField(verbose_name='email', max_length=100, unique=True)
    age = models.PositiveIntegerField(null=True)
    info = RichTextField(blank=True, null=True)
    image = models.ImageField(upload_to='media/stuff_images')
    inst = models.URLField(blank=True)
    REQUIRED_FIELDS = ['email', ]

def __str__(self):
    return self.email

def get_email(self):
    return self.object.email

class Post(models.Model): DEFAULT_TRAINER_ID = 1

article = models.CharField(max_length=50, default='Article text')
slug = models.SlugField(max_length=30)
keywords = models.CharField(max_length=100)
text = RichTextField(blank=True, null=True)
trainer = models.ForeignKey(UserTrainer, on_delete=models.CASCADE, null=False, default=1)

def __str__(self):
    return self.article

class Meta:
    verbose_name = 'Post'
    verbose_name_plural = 'Posts'

#admin.py
class CustomUserAdmin(UserAdmin):
    model = UserTrainer
    add_form = CustomUserCreationForm
    fieldsets = (
        *UserAdmin.fieldsets,
        (
            'TrainerInfo',
            {
                'fields': (
                    'age', 'info', 'image', 'inst',
                )
            }
        )
    )
admin.site.register(UserTrainer, CustomUserAdmin)
@admin.register(Post)
class PostAdmin(admin.ModelAdmin):
    list_display = ('article', 'slug','trainer')
    list_display_links = ('article',)
    fields = ('article', 'slug', 'keywords', 'text',)
    readonly_fields = ('trainer',)

CodePudding user response：

The problem is that you are are not specifying user when you save your post, so you should override your save method in admin.py, try this (OFFICIAL DOCS):

admin.site.register(UserTrainer, CustomUserAdmin)
@admin.register(Post)
class PostAdmin(admin.ModelAdmin):
    list_display = ('article', 'slug','trainer')
    list_display_links = ('article',)
    fields = ('article', 'slug', 'keywords', 'text',)
    readonly_fields = ('trainer',)

    def save_model(self, request, obj, form, change):
        obj.trainer = request.user
        super().save_model(request, obj, form, change)
