将slug字段预填充到Django站点的表单字段中

Question

我创建了一个用于在网站上发布帖子的表单。在模型中有一个SlugField，它是admin.py中预先填充的字段，用于帖子的标题。

forms.朋友

class TestPostModelForm(forms.ModelForm):
    title = forms.CharField(
                max_length=70,
                label="Titolo",
                help_text="Write post title here. The title must be have max 70 characters",
                widget=forms.TextInput(attrs={"class": "form-control form-control-lg"}),
                )
    slug_post = forms.SlugField(
                    max_length=70,
                    label="Slug",
                    help_text="Slug is a field in autocomplete mode, but if you want you can modify its contents",
                    widget=forms.TextInput(attrs={"class": "form-control form-control-sm"}),
                    )
.....
    class Meta:
        model = TestPostModel
        fields = [
                "title",
                "slug_post",
                "description",
                "contents",
....
                ]

如果我从管理面板创建一个帖子，则会自动正确填充slug，但如果我从表单创建一个帖子，则不会发生相同的事情。在第二种情况下，创建了帖子但是slug字段保持为空。

我已经读过我必须使用slugify在我的表单中创建一个预先填充的字段，但我还不知道我可以用哪种方法做到这一点。

我可以举个例子吗？

Answer 1

以下是views.py中的示例

form = PostForm(request.POST):
   if form.is_valid():
     post = form.save(commit=False)
     post.slug = slugify(post.title)
     post.save()
    ...

Answer 2

在coderasha指示上稍微精确一点：从表单中删除slug字段很重要。

就我而言：

class TestPostModelForm(forms.ModelForm):
    title = forms.CharField(
                max_length=70,
                label="Titolo",
                help_text="Write post title here. The title must be have max 70 characters",
                widget=forms.TextInput(attrs={"class": "form-control form-control-lg"}),
                )

.....
    class Meta:
        model = TestPostModel
        fields = [
                "title",
                "description",
                "contents",
....
                ]
