the inline class,modified the form and formset .But nothing is
changed,and no mistake happen.
I see the django website release notes,which said has fixed inline
form bug.I do know how to do .
this is my model.py
#coding=utf-8
# Create your models here.
from django.db import models
from django.contrib import admin
from django import forms
from django.forms.models import inlineformset_factory
from django.forms import ModelForm
class totattrib(models.Model):
name=models.CharField(max_length=30,unique=True)
description=models.CharField(max_length=60,blank=True)
def __unicode__(self):
return self.name
class subattrib(models.Model):
name=models.ForeignKey(totattrib)
subname=models.CharField(max_length=30,unique=True)
description=models.CharField(max_length=60,blank=True)
def __unicode__(self):
return self.subname
class resources(models.Model):
name = models.CharField(max_length=60,unique=True)
urls = models.URLField()
startingdate = models.DateField(auto_now_add=True)
endingdate = models.DateField(blank=True,null=True)
published_choices = (
('y', 'yes'),
('n', 'no'),
)
published = models.CharField(max_length=2,
choices=published_choices)
usages = models.URLField(blank=True)
attribs = models.ManyToManyField(subattrib,
through='resourcehash')
def show_sub(value):
objects = value.attribs.all().order_by("id")
str='<table style="border:none;"><tr>'
for obj in objects:
str += '<td style="border:none;">'+obj.subname+'</td>'
str+='</tr></table>'
return str
show_sub.allow_tags=True
def __unicode__(self):
return self.name
class resourcehash(models.Model):
resource=models.ForeignKey(resources)
attrib=models.ForeignKey(subattrib)
def __unicode__(self):
return self.resource.name + " " + self.attrib.subname
class resourcesadminform(forms.ModelForm):

fields = ('id','resource', 'attrib')
resourceFormSet = inlineformset_factory(resources, resourcehash,
fk_name="resource",form=resourceadminform, can_delete=False)
