Question

对不起。当我提交表格后，我得到以下错误。

TypeError at /foodlogin/
context must be a dict rather than RequestContext.

我的views.py如下。我的登录表单需要识别数据库信息：Models.py-User类，并且需要会话保留所有网页。此外，登录成功将重定向到“foodmenu.html”。

# -*- coding: utf-8 -*-
from django.shortcuts import redirect
from django.template.loader import get_template
from django.http import HttpResponse
from castecfood.models import User
from castecfood import forms
from django.template import RequestContext

def index(request):    
    template=get_template('index.html')
    html=template.render(locals())
    return HttpResponse(html)

def foodlogin(request):    
    if request.method=='POST':
       form=forms.LoginForm(request.POST)
       if form.is_valid():
          login_id=request.POST['user_id'].strip()
          login_password=request.POST['user_pass']
          try:
             user=User.objects.get(jobnumber=login_id)
             if user.jobnumber==login_id anduser.personpwd==login_password:
             request.session['user_id']=user.jobnumber
             request.session['user_pass']=user.personpwd
             return redirect('/foodmenu/')
             else:
                message="ID或密碼有錯喔，請再檢查一次"
          except:
            message="目前無法登入"
       else:
          message="請檢查輸入的欄位內容"
    else:
        form=forms.LoginForm()

    template=get_template('foodlogin.html')
    request_context=RequestContext(request)
    request_context.push(locals())
    html=template.render(request_context)    
    reponse=HttpResponse(html)
    return reponse

def foodmenu(request):
    template=get_template('foodmenu.html')  
    html=template.render(locals())
    return HttpResponse(html)

我的foodlogin.html文件：它用于登录用户输入“user.jobnumber和user.personpwd”

<!--foodlogin.html (castecsystem project)>-->

            {% block content %}

               {% csrf_token %}                 
               <fieldset>                  
               {{form.as_table}}
               </fieldset>                          
               <br/>
               <input type="submit" value="Login">
               <input type="reset" value="Reset">
               </form>
               </div>
               </section>

我的forms.py文件：

# -*- coding: utf-8 -*-
from django import forms

class LoginForm(forms.Form): 
    user_id=forms.CharField(label='Your ID:', max_length=10)
    user_pass=forms.CharField(label='Your Password:',  
    widget=forms.PasswordInput())

我的urls.py文件：

urlpatterns = [
url(r'^admin/', include(admin.site.urls)), 
url(r'^$', index),
url(r'^foodlogin/$', foodlogin),
url(r'^foodmenu/$', foodmenu),
url(r'^captcha/', include('captcha.urls'))
]

我不知道如何解决这个问题。我试了很长时间，但我还没有解决了。请让我知道如何解决它。我非常感激。

您需要更改：

html=template.render(request_context)

为：

html=template.render(context=locals(), request=request)

主题：Django问题：上下文必须是dict而不是RequestContext
