Django Admin显示外键值

Question

I'm trying to display the foreign key value itself in the Django Admin Panel.

admins.py:
class CateogoriesAdmin(admin.ModelAdmin):

list_display = ('category_name',)

class CateogoriesItemAdmin(admin.ModelAdmin):

list_display = ('category_name', 'item_name', 'item_description',)


Models.py:
class Category(models.Model):
    category_name = models.CharField(max_length=50)

class CategoryItems(models.Model):
    category_name = = models.ForeignKey(Categories, related_name='categoriesfk', on_delete=models.PROTECT)
    item_name = models.CharField(max_length=50)
    item_description = models.CharField(max_length=100)

With the above, I just get Categories Object (1) as value, I want to display the actual value in the Django admin panel not object (1), eg if there is a category called "Bicycle", it should display Bicycle.

Answer 1

you have to tell django what to show when representing object category as string. for example

class Category(models.Model):
    category_name = models.CharField(max_length=50)

    def __str__(self):
        return self.category_name
