Exclude fields from admin form

[frlan]

I need to exclude fields from a child admin.py so I've added a exclude to the child admin class.

class BookAdmin(PolymorphicChildModelAdmin):
    base_model = Part
    exclude = (
        'SKU',
        'name',
        'unit'
    )

Unfortunately this is not removing the files from from. What is the correct way on doing this?

That seems like an error. As workaround, you can define your own form, and provide the exclude in it's Meta options.

something like this likely works:

class BookAdminForm(forms.ModelForm):
    class Meta:
        model = ..
        exclude = (..)

I have tried this and this seems not to work. Maybe I messed something else up too.

I just retired it with a minimal example:

admin.py

from .models import Project, ArtProject, ResearchProject
from django.contrib import admin
from polymorphic.admin import PolymorphicParentModelAdmin, PolymorphicChildModelAdmin

# Register your models here.

class ArtProjectAdmin(PolymorphicChildModelAdmin):
    base_model = 'ArtProject'
    fields = ('artist')

class ResearchProjectAdmin(PolymorphicChildModelAdmin):
    base_model = 'ResearchProject'

class ProjectAdmin(PolymorphicParentModelAdmin):
    base_model = 'Porject'
    child_models = (
        (ArtProject, ArtProjectAdmin),
        (ResearchProject, ResearchProjectAdmin)
    )

admin.site.register(Project)
admin.site.register(ArtProject)

models.py

from django.db import models
from polymorphic.models import PolymorphicModel

class Project(PolymorphicModel):
    topic = models.CharField(max_length=30)

class ArtProject(Project):
    artist = models.CharField(max_length=30)

class ResearchProject(Project):
    supervisor = models.CharField(max_length=30)

Maybe it helps.
