Django中的CSRF失败

Question

为什么在存在{％csrf_token％}的情况下出现以下错误？

禁止（403）CSRF验证失败。 请求中止。

这是我使用了很长时间的示例视图。

view.py

def editModel(self,request, offset):
        if 'user' in request.session :
             user = request.session['user']
            if request.method == 'POST':
                if 'editModel' in request.POST:
                    offset = int(offset)
                    fields = ProfilModel.objects.filter(name=user)
                    workingModelsFiles = WorkingWithModelsFiles()
                    listModel = workingModelsFiles.getCurrentModel(user, offset)
                    modelView = self.listModels(user)[offset-1]
                    loadModels = "document.getElementById('x3dElement" + str(offset) + "').runtime.showAll();"
                    params = {'id ': offset,
                              'userName' : request.session['user'],
                              'surname' : fields[0].surname,
                              'listModel': listModel,
                              'model': modelView,
                              'bodyLoadModels': loadModels
                              }
                    params.update(csrf(request))
                    return render_to_response('editModel.html', params)

            else:
                offset = int(offset)
                fields = ProfilModel.objects.filter(name=user)
                workingModelsFiles = WorkingWithModelsFiles()
                listModel = workingModelsFiles.getCurrentModel(user, offset)
                modelView = self.listModels(user)[offset-1]
                loadModels = "document.getElementById('x3dElement" + str(offset) + "').runtime.showAll();"
                params = {'id ': offset,
                          'userName' : request.session['user'],
                          'surname' : fields[0].surname,
                          'listModel': listModel,
                          'model': modelView,
                          'bodyLoadModels': loadModels
                          }
                params.update(csrf(request))
                return render_to_response('editModel.html', params)
        else:
            return HttpResponseRedirect("/login/")

它存在于模板{％csrf_token％}中，再次给我csrf错误

template.html

......
<div class="tab_container">
            <div id="tab1" class="tab_content">
                <table class="tablesorter" cellspacing="0"> 
                <tbody> 
                <form action="{% url 'edit_model' listModel.0.id_model  %}"  method="post" >
                {% csrf_token %}
                    {% for item in listModel %} 
                        <tr>
                            <td rowspan="3" style="width: 300px;"> {{ model | safe }} </td>
                            <td> Name Model: <i><input class="text_field" type="text" id='id_Model' name="Model" value="{{ item.modelName }}" /> </i> </td>
                        </tr>

                        <tr>
                            <td>  Author:  <i> <input class="text_field" type="text" id='id_Author' name="Author" value="{{ item.author }}" /> </i> </td>
                        </tr>
                        <tr>
                            <td> <input type="submit" name="editModel" value="Edit" /> </td>
                        </tr>
                    {% endfor %}
                </form>
                </tbody> 
                </table>
            </div><!-- end of #tab1 -->

您是否尝试过使用RequestContext代替params.update（csrf（request））？ 喜欢：

params = {'id ': offset,
          'userName' : request.session['user'],
          'surname' : fields[0].surname,
          'listModel': listModel,
          'model': modelView,
          'bodyLoadModels': loadModels
          }
ctx = RequestContext(request, params)
return render_to_response('editModel.html', context_instance=ctx)
