誰和誰在Django模型

Question

我想弄清楚人們將如何寫評論，以及如何存儲誰寫和誰寫的。我想看看爲一個人寫的評論UserProfile.Comments ...

任何人都可以幫助我嗎？

MODELS.PY

class UserProfile(models.Model): 
    comments = models.ForeignKey("Comments", null=True, blank=True) 


class Comments(models.Model): 
    comment = models.CharField(max_length=500, null=False, blank=False) 
    who_wrote = models.ForeignKey(User) 

VIEW.PY（這裏我插）

def writecomment(request, username): 
    if request.method == 'POST': 
     form = CommentForm(request.POST) 
     if form.is_valid(): 
      form.save(commit=False) 
      form.user = request.user 
      form.user_id = get_object_or_404(User, username=username).id 
      #frm = form.save() 

      usr = get_object_or_404(UserProfile, user = request.user) 
      usr.Comments = form #append?? 
      usr.save() 

    else: 
     form = CommentForm(request.POST) 

    return render_to_response("writecomment.html", {"form": form}, context_instance=RequestContext(request))

我相信，你的模型可以創建有點不同，使這項工作更容易。只需要考慮一些事情。

1. 每個用戶可以有多個評論嗎？ UserProfile有一個名爲comments的字段，暗示它可能是。這可能更好地模仿爲多對多領域。

2. 應該UserProfile鏈接到用戶？

3. 好像Comments可能需要支持2個用戶，一個來自用戶，另一個來自用戶。

class UserProfile(models.Model): 
    user = models.OneToOneField(User) # each user can have exactly 1 profile 
    comments = models.ManyToManyField(Comment) # each user can have mutilple comments 


class Comment(models.Model): 
    text = models.CharField(max_length=500, null=False, blank=False) 
    to = # shoudl this be foreign key or many to many? 
    # can a comment reference multiple users or just one user or no user? 

隨着上述變化，得到了評論給用戶或從用戶變得輕鬆了許多
