我有一个作者模型和书籍模型.用户可以修改给定作者的所有书籍的属性.我希望能够为每本书显示错误,而不是列出顶部的所有错误,我该怎么做？
楷模
from django.db import models
from django.forms import ModelForm,Textarea
from django import forms
class Author(models.Model):
fname = models.CharField(max_length=100)
lname = models.CharField(max_length=100)
def fullname(self):
return '%s %s' % (self.fname,self.lname)
fullname = property(fullname)
def __unicode__(self):
return self.fullname
class Books(models.Model):
author = models.ForeignKey(Author)
title = models.CharField(max_length=50)
publisher = models.CharField(max_length=50)
edition = models.CharField(max_length=50)
comment = models.TextField()
def __unicode__(self):
return self.title
视图
def author_books_edit(request,author_id):
a = get_object_or_404(Author,pk=author_id)
authorsbooks = a.books_set.all()
bookformset = inlineformset_factory(Author,Books,can_delete=True,can_order=True,exclude=('company',),extra=1)
formset = bookformset(instance=a)
if request.method == "POST":
formset = bookformset(request.POST,request.FILES,instance=a)
if formset.is_valid():
formset.save()
else:
form_errors = formset.errors
return render_to_response('test/authors_books_edits.html',{'author': a,'authorsbooks': authorsbooks,'formset': formset,'form_errors': form_errors},context_instance=RequestContext(request))
return render_to_response('test/authors_books_edits.html',},context_instance=RequestContext(request))
模板
#all errors are here
{% for dict in form_errors %}
{{ dict }}
{% endfor %}
#all forms are here,i want to pair the errors for each form
<form method="post" action="/test/{{ author.id }}/books/">
{% csrf_token %}
<table>
{{ formset }}
</table>
<input type="submit" value="Submit"/>
</form>
<form method="post" action="/test/{{ author.id }}/books/">
{% formset.management_form %}
{% csrf_token %}
<table>
{% for x in formset %}
{{x.errors }}
{{ x }}
{% endfor %}
</table>
<input type="submit" value="Submit"/>
解决方法
编辑
authors_books_edits.html
<form method="post" action="/test/{{ author.id }}/books/">
{% csrf_token %}
{{ formset.management_form }}
{% for form in formset.forms %}
{{ form.non_field_errors }}
{{ form.errors }}
<table>
{{ form.as_table }}
</table>
{% endfor %}
<input type="submit" value="Submit"/>
</form>
views.py
from django.shortcuts import *
from django.forms.models import inlineformset_factory
from .models import *
def author_books_edit(request,instance=a)
if formset.is_valid():
formset.save()
else:
form_errors = formset.errors
return render_to_response('authors_books_edits.html',context_instance=RequestContext(request))
return render_to_response('authors_books_edits.html',context_instance=RequestContext(request))
models.py
from django.db import models
class Author(models.Model):

lname = models.CharField(max_length=100)
def fullname(self):
return '%s %s' % (self.fname,self.lname)

def __unicode__(self):
return self.title
urls.py
from django.conf.urls.defaults import patterns,include,url
urlpatterns = patterns('testapp.views',url(r'test/(?P<author_id>\d+)/books/$','author_books_edit'),)
您可以制作另一个临时应用来测试它.
它看起来像这样：http://imageshack.us/photo/my-images/824/screenshotat20120227190.png/
==结束编辑
您可以这样迭代表单：
{% for form in formset.forms %}
{{ form }}
{% endfor %}
在这种情况下,请参阅Django使用模板文档显示表单：https://docs.djangoproject.com/en/dev/topics/forms/#displaying-a-form-using-a-template
然后,更有趣的是,自定义表单模板(请参阅form.non_field_errors)：
https://docs.djangoproject.com/en/dev/topics/forms/#customizing-the-form-template
