CSRF en échec Django

Question

Pourquoi en présence je reçois {% csrf_token%} est l'erreur suivante?

Interdite (403) vérification CSRF a échoué. Demande annulée

Ceci est une vue exemple que je l'utilise, si longtemps.

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/") 

Il est présent dans le modèle {%}% csrf_token encore une fois me donne une erreur sur CSRF

Answer 1

Avez-vous essayé d'utiliser un RequestContext au lieu de params.update (CSRF (demande))? Comme :

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)
