How to solve Unknow Field Error in Django
I am building a project a project by Django 2.0.2. What I want to do is making one of the fieldsets in admin page change automatically according to the database. Here is part of my code:
models.py
class Product(BaseModel):
number=model.IntergerField("Food", null=True, blank=True, help_text="Food")
@property
def number(self):
return 10 #just return a number for testing
admin.py
class ProductAdmin(admin.ModelAdmin):
list_display=("number")
fieldsets=(('<h1>Food</h1>'), {'fields':('number')})
When I refresh the admin page, it shows "Unkown fields (number) specified for Product. Check fieldset attribute of class ProductAdmin". I am new to Django and not sure about what goes wrong. In the admin.py, I have added "number" field but the error still exist. How can I solve it? Many Thanks and Happy New Year.

number is not a field, it is a property. You can add this to the readonly_fields:
class ProductAdmin(admin.ModelAdmin):
list_display=('number',)
readonly_fields = ('number',)
fieldsets=(('<h1>Food</h1>'), {'fields':('number')})You should also add a short_description to your property, like:
class Product(BaseModel):
number=model.IntergerField("Food", null=True, blank=True, help_text="Food")
# no decorator
def number(self):
return 10 #just return a number for testing
number.short_description = "The number"
number = property(number)as is documented in the ModelAdmin options section.
