Question

I’m trying to add custom fields to an InlineFormset using the following code, but the fields won’t show up in the Django Admin. Is the InlineFormset too locked down to allow this? My print ‘ding’ test fires as expected, I can print out the form.fields and see them all there, but the actual fields are never rendered in the admin.

admin.py

from django.contrib import admin import models from django.forms.models import BaseInlineFormSet from django import forms from forms import ProgressForm from django.template.defaultfilters import slugify  class ProgressInlineFormset(BaseInlineFormSet):     def add_fields(self, form, index):         print 'ding'         super(ProgressInlineFormset, self).add_fields(form, index)         for criterion in models.Criterion.objects.all():             form.fields[slugify(criterion.name)] = forms.IntegerField(label=criterion.name)  class ProgressInline(admin.TabularInline):     model = models.Progress     extra = 8     formset = ProgressInlineFormset  class ReportAdmin(admin.ModelAdmin):     list_display = ('name', 'pdf_column',)     search_fields = ['name',]     inlines = (ProgressInline,)  admin.site.register(models.Report, ReportAdmin) 

Answer 1

model = models.Progress 

In the admin there will be only the fields defined in this Progress model. You have no fields/fieldsets option overwriting it.

If you want to add the new ones, there are two options:

• In the model definition, add those new additional fields (make them optional!)

• In the admin model (admin.TabularInline), add something something like:

  fields = (‘newfield1’, ‘newfield2’, ‘newfield3’)

Take a look at fields, fieldsets.
