from django.shortcuts import render_to_response
from django.template import RequestContext
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
$来自myproject.myapp.models的文件
从myproject.myapp.forms导入文件
从myproject.myapp.forms导入DocumentForm
DocumentForm2
def list（请求）
＃处理文件上传
如果request.method =='POST'：
form = DocumentForm（request.POST，prefix =form）
form2 = DocumentForm2 （request.POST，prefix =form2）
如果form.is_valid（）或form2.is_valid（）：
newdoc = Document（docfile = request.FILES ['docfile'] ）
newdoc.save（）
＃在POST之后重定向到文档列表
return HttpRes ponseRedirect（reverse（'myproject.myapp.views.list'））
else：
form = DocumentForm（prefix =form）＃一个空的，未绑定的形式
form2 = DocumentForm2 =form2）＃一个空的，未绑定的表单
＃加载列表页面的文档
documents = Document.objects.all（）
＃渲染列表页面与文件和表单
返回render_to_response（
'list.html'，
{'documents'：documents，'form'：form}，
context_instance = RequestContext请求）
）
forms.py
＃ - * - 编码：utf-8 - * -
from django import forms
class DocumentForm（forms.Form）：
docfile = forms.FileField（
label ='选择一个文件'
class DocumentForm2（forms.Form）：
docfile2 = forms.FileField（
label ='选择一个文件'
）
首先，您的意见中定义了2个表单方法表单和 form2 ，但您只需将表单添加到您的上下文。
其次，您不要将两个表单放在两个不同的< form> 标签中。你应该把它们放在一起，所以你可以同时提交它们。
第三，不相关，但你不能命名你的视图方法列表。这是数据结构 list 的django关键字，如果您尝试在其他函数中使用 list ，可能会遇到很大的麻烦在您的视图文件中。
编辑
您继续使用变量 {{form.something}} 但是你有2个表单，所以你只是渲染第一个表单两次，但完全忽略了第二个表单。你应该：
< form action ={％urllist％}method =postenctype =多部分/格式数据>
{％csrf_token％}
{{form.as_p}}
{{form2.as_p}}
< p>< input type =submitvalue =上传/>< / p为H.
< / form>
ReEdit：
我不知道是什么导致403发生，但是让我们尝试用 render 替换 render_to_response / p>
从django.shortcuts import render
def list（request）：
＃你的代码这里
return render（request，'list.html'，{'documents'：documents，'form'：form，'form2'：form2}）
I know this question has been answered before on this site, but for the life of me I can't figure it out. I want to submit two forms at once, with one submit button. Please, can anybody identify what is wrong with my code, this is driving me insane.

views.py
# -*- coding: utf-8 -*-
from django.shortcuts import render_to_response
from django.template import RequestContext
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from myproject.myapp.models import Document
from myproject.myapp.forms import DocumentForm
from myproject.myapp.forms import DocumentForm2
def list(request):
# Handle file upload
if request.method == 'POST':
form = DocumentForm(request.POST, prefix="form")
form2 = DocumentForm2(request.POST, prefix="form2")
if form.is_valid() or form2.is_valid():
newdoc = Document(docfile=request.FILES['docfile'])
newdoc.save()
# Redirect to the document list after POST
return HttpResponseRedirect(reverse('myproject.myapp.views.list'))
else:
form = DocumentForm(prefix="form") # A empty, unbound form
form2 = DocumentForm2(prefix="form2") # A empty, unbound form
# Load documents for the list page
documents = Document.objects.all()
# Render list page with the documents and the form
return render_to_response(
'list.html',
{'documents': documents, 'form': form},
context_instance=RequestContext(request)
)
forms.py
# -*- coding: utf-8 -*-
from django import forms
class DocumentForm(forms.Form):
docfile = forms.FileField(
label='Select a file'
)
class DocumentForm2(forms.Form):
docfile2 = forms.FileField(
label='Select a file'
)
First, you have 2 forms defined in your views method form and form2, but you only add form to your context.
Secondly, you don't put 2 forms in two different <form> tags. You should put them in one so you could submit them at the same time.
Thirdly, not related, but you CANNOT name your views method list. That's a django keyword for data structure list, you could run into huge trouble if you try to use list in other functions in your views file.
Edit:
You keep using variable {{ form.something }} but you have 2 forms, so you just render the first form twice but completely ignored the second form. You should:
<form action="{% url "list" %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form.as_p }}
{{ form2.as_p }}
<p><input type="submit" value="Upload"/></p>
</form>
ReEdit:
I'm not sure what caused the 403 to happen, but let's try replace render_to_response with render:
from django.shortcuts import render
def list(request):
# your code here
return render(request, 'list.html', {'documents': documents, 'form': form, 'form2': form2})
