I have TabularInline form does not have add permission and not all fields
are read-only.
Its model has a FK to parent model without any restrictions.
When I try to create a new parent model via contrib.admin form KeyError
exception raised.
This example application fails on Django 2.1, Python 3.6 when I try to
visit
http://localhost:8000/admin/app/parentmodel/add/
It raises {{{KeyError: 'editable_field'}}}
=== models.py
{{{
from django.db import models
class ParentModel(models.Model):
name = models.CharField(max_length=255)
class InlineModel(models.Model):
editable_field = models.CharField(max_length=255)
readonly_field = models.CharField(max_length=255)
parent = models.ForeignKey(ParentModel, on_delete=models.CASCADE)
}}}
=== admin.py
{{{
from django.contrib import admin
from .models import InlineModel, ParentModel
class InlineModelInline(admin.TabularInline):
model = InlineModel
fields = (
'editable_field',
'readonly_field',
)
readonly_fields = (
'readonly_field',
)
def has_add_permission(self, request, obj):
return False
@admin.register(ParentModel)
class ParentModelAdmin(admin.ModelAdmin):
fields = ['name']
inlines = [InlineModelInline]
}}}
