<pre><code>model = models.Progress
</code></pre>

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:

<ul>
<li>In the model definition, add those new additional fields (make them optional!)</li>
<li>In the admin model (admin.TabularInline), add something something like:

fields = ('newfield1', 'newfield2', 'newfield3')</li>
</ul>

Take a look at <a href="http://docs.djangoproject.com/en/dev/ref/contrib/admin/#fields" rel="nofollow noreferrer">fields</a>, <a href="http://docs.djangoproject.com/en/dev/ref/contrib/admin/#fieldsets" rel="nofollow noreferrer">fieldsets</a>.

I did it another way:
forms.py:
<pre><code>from django import forms
class ItemAddForm(forms.ModelForm):
 my_new_field = forms.IntegerField(initial=1, label='quantity')
 class Meta:
 model = Item
</code></pre>
admin.py:
<pre><code>from django.contrib import admin
from forms import *
class ItemAddInline(admin.TabularInline):
 form = ItemAddForm
 fields = (..., 'my_new_field')
</code></pre>
This works so far, I only need to override somehow the save method to handle this new field. See this: <a href="http://docs.djangoproject.com/en/dev/ref/contrib/admin/#form" rel="nofollow noreferrer">http://docs.djangoproject.com/en/dev/ref/contrib/admin/#form</a> . It says that by default Inlines use BaseModelForm, which is send to formset_factory. It doesn't work for me, tried to subclass BaseModelForm with errors (no attribute '_meta'). So I use ModelForm instead.

blocks|key|787272|text|您可以通过另一种方式(动态表单)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|787273|admin.py|offset|length|style|BOLD|787274|class+ProgressInline(admin.TabularInline):

You can do it by another way (Dynamic forms):

admin.py

<pre><code>class ProgressInline(admin.TabularInline):
 model = models.Progress
 extra = 8

 def get_formset(self, request, obj=None, **kwargs):
 extra_fields = {'my_field': forms.CharField()}
 kwargs['form'] = type('ProgressForm', (forms.ModelForm,), extra_fields)
 return super(ProgressInline, self).get_formset(request, obj, **kwargs)
</code></pre>

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

<pre><code>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)
</code></pre>
