Django：用户过滤草稿会导致错误 [英] Django: Filtering drafts by user causes error

问题描述

我试图使用request.user变量过滤一组数据库中的草稿对象。他们是因为某些原因我得到以下列出的错误。如何解决这个错误？

功能：

  def posting_draft （请求）：
 user = request.user 
 user_drafts = Draft.objects.filter（user = user）
 drafts = dict（）
 for user in user_drafts 
草案[d.title] = d.id 
返回render_to_response（'posting_draft.html'，{'STATIC_URL'：STATIC_URL'，draft_l'：drafts}）
  / pre> 
 
 
错误：
  int（）参数必须是字符串或数字，而不是'SimpleLazyObject'
  
 
 
解决方案
 .user是一个 SimpleLazyObject ，直到被访问。尝试将查询更改为以下内容：
  user_drafts = Draft.objects.filter（user = user.pk）
  
 
I'm trying to filter through a set of drafts objects in a database using the request.user variable. They are For some reason I get the error listed bellow. How can I fix this bug?

Function:
def posting_draft(request):
    user = request.user
    user_drafts = Draft.objects.filter(user = user)
    drafts = dict()
    for d in user_drafts:
        drafts[d.title] = d.id
    return render_to_response('posting_draft.html', {'STATIC_URL':STATIC_URL, 'draft_l' : drafts})
Error:
int() argument must be a string or a number, not 'SimpleLazyObject'

解决方案
Since request.user is a SimpleLazyObject until it is accessed. Try changing your query to the following:
user_drafts = Draft.objects.filter(user = user.pk)
