Python Django没有规定用户可以选择什么

我对Django很陌生，所以不要评判我：）。我正在做一个博客项目，除了一件事，其他一切都很好。创建帖子时，用户可以选择以前登录过的任何其他作者。有没有办法将作者名称空间设置为当前登录的用户？这是我的密码：

我什么都试过了，什么都没用。有人能帮我吗？

在您的

PostForm

中，从字段中删除

author

，因此用户无法编辑它：

fields = ['title', 'text']

然后在

CreatePostView

中，删除

def get_queryset（）

方法，因为它在这里什么都不做。您应该替代

form\u valid

方法，这样您就有机会更新由表单创建的模型

def form_valid(self, form):
    self.object = form.save(commit=False)  # the form's save method returns the instance
    self.object.author = self.request.user  # here you assign the author
    self.object.save()
    return HttpResponseRedirect(self.get_success_url())

或者，要尽可能靠近

CreateView

父类：

def form_valid(self, form):
    form.instance.author = self.request.user
    return super().form_valid(form)  # this will call `CreateView`'s `form_valid()` method, which saves the form.

---

您没有限制表单的modelchoice字段的queryset。默认情况下，它使用

model.objects.all（）

作为查询集。在您的视图中，您可以在呈现表单之前编辑查询集，如

form.fields['field\u name']]。查询集=

，因为听起来这将根据发出请求的用户而动态变化。
