改变 Django 形式

Question

我如何调整我的代码，以便用户不能为新帖子选择另一个用户。我想让登录用户自动添加为作者。我尝试将 views.py 中的字段部分设置为内容字段，但它不起作用models.pyclass post(models.Model):    author = models.ForeignKey(User, on_delete=models.CASCADE)    content = models.CharField(max_length=140)views.pyclass CreatePostView(CreateView):    model = post    fields = '__all__'    template_name = 'users/create.html'我的表单.html<form method="post">    {% csrf_token %}    {{ form.as_p }}    <input type="submit" value="Login"></form>

Answer 1

class CreatePostView(CreateView):

    model = post

    template_name = 'users/create.html'

    fields = ['content']

    def form_valid(self, form):

        form.instance.author = self.request.user

        return super().form_valid(form)

Answer 2

您需要做三件事：

1. 保护页面，使匿名用户无法访问它，使用LoginRequiredMixin

2. 从字段中删除用户

3. 提交表单后在提交的表单中输入当前用户，使用form_valid方法

from django.views.generic.edit import CreateView

from django.contrib.auth.mixins import LoginRequiredMixin

class CreatePostView(LoginRequiredMixin, CreateView):

    model = Post

    fields = ["content"]

    template_name = "create.html"

    def form_valid(self, form):

        form.instance.user = self.request.user

        return super().form_valid(form)

Answer 3

request.user.username
