python之'QueryDict' 对象没有属性 'id'

在“面板”页面上，我有一个选择字段，其中列出了已上传的文档或我通常所说的“机器人”。此列表仅显示当前用户上传的“机器人”。

panel\forms.py 
 
from django import forms 
import os 
 
from upload.models import Document 
 
#### RETRIEVE LIST OF BOTS UPLOADED BY CURRENT USER #### 
def get_files(user): 
    bots = Document.objects.filter(user=user.id) 
    file_list = [] 
    for b in bots: 
        file_list.append((b.id,b.docfile)) 
    return file_list 
 
class botForm(forms.Form): 
 
    def __init__(self, user, *args, **kwargs): 
        super(botForm, self).__init__(*args, **kwargs) 
        self.fields['bot'] = forms.ChoiceField(choices=get_files(user)) 

这工作正常并显示所有用户机器人的列表。当我尝试将这些值传递到“游戏”页面并在此处访问它们时，问题就出现了。

game\views.py 
 
from django.shortcuts import render_to_response 
from django.template import RequestContext 
from django.http import HttpResponseRedirect 
from django.core.urlresolvers import reverse 
 
from game.models import game 
from game.forms import GameForm 
from upload.models import Document 
from panel.forms import botForm 
import league 
 
def RPS(request): 
    if request.method == 'POST': # If the request is a POST method... 
 
        if 'PanelPlay' in request.POST: 
            panel = botForm(request.POST) 
            if panel.is_valid(): 
                print panel.cleaned_data['bot'] 
 
        elif 'GamePlay' in request.POST: 
            form = GameForm(request.POST) # A form bound to the POST data 
            if form.is_valid(): # All validation rules pass 
                leagueOuput = [] 
                leagueOutput = league.run(form.cleaned_data['bot1'],form.cleaned_data['bot2']) 
                newGame = game() 
                newGame.bot1 = leagueOutput[0] 
                newGame.bot2 = leagueOutput[1] 
                newGame.bot1wins = leagueOutput[2] 
                newGame.bot2wins = leagueOutput[3] 
                newGame.save() 
                return HttpResponseRedirect(reverse('game.views.RPS')) # Redirect after POST 
 
    form = GameForm() # An unbound form 
    results = game.objects.all()    # Load messages for the list page      
 
    return render_to_response('game.html', {'results': results, 'form': form}, context_instance=RequestContext(request)) 

尝试访问和验证面板数据时，出现以下错误。

'QueryDict' object has no attribute 'id'

指的是这一行。

bots = Document.objects.filter(user=user.id) 

我发现并阅读了许多类似的问题，但我似乎无法将他们的解决方案应用到我自己的项目中。

在此先感谢您提供的所有帮助。

请您参考如下方法:

当您构造 botForm 时，您将传递 request.POST(一个 QueryDict)作为 user 参数。你是说

panel = botForm(request.user, data=request.POST)  

?

(假设您正在使用 django 身份验证)。
