我怎样才能改变模型标签并给它一个自定义名称

Question

我想为模型中的一个标签创建自定义名称这是我的 forms.py

class PostForm(forms.ModelForm):
    body = forms.CharField(widget=PagedownWidget)
    publish = forms.DateField(
        widget=forms.SelectDateWidget,
        initial=datetime.date.today,
    )

    class Meta:
        model = Post
        fields = [
            "title",
            "body",
            "author",
            "image",
            "image_url",
            "video_path",
            "video",
            "publish",
            "tags",
            "status"
         ]

我想更改而不是视频我希望它说嵌入。我检查了文档，但没有找到任何可以帮助我做到这一点的东西。有没有可能我不必重新排列我的模型？如果是这样怎么办？谢谢

Answer 1

是的，you can。只需使用 label 参数：

class PostForm(forms.ModelForm):
    ...
    video = forms.FileField(label='embed')

或在您的 Meta class:

中定义它

class PostForm(forms.ModelForm):
    ...
    class Meta:
        ...
        labels = {
            "video": "embed"
            ...
        }

Answer 2

来自documentation：

You can specify the labels, help_texts and error_messages attributes of the inner Meta class if you want to further customize a field.

文档的该部分下方有示例。所以，你可以这样做：

class Meta:
    model = Post
    labels = {
        "video": "Embed"
    }

Answer 3

在不编辑表格的情况下实现此目的的一种简单方法是 change the verbose_name 在模型上。对于模型上的 video 字段，您可以将表单上的标签从 "video" 更改为 "embed"，如下所示：

class Post(models.Model)
    video = models.UrlField(verbose_name="embed")
    # Other fields

Answer 4

class Meta:

    model = Book
    fields = ('title', 'publication_date', 'author', 'price', 'pages','book_type',)
    labels  = {
        'title':'Titulo', 
        'publication_date':'Data de Publicação', 
        'author':'Autor', 
        'price':'Preço', 
        'pages':'Número de Páginas',
        'book_type':'Formato'
        }
    widgets = {
        'title': forms.TextInput(attrs={'class':'form-control'}),
        'publication_date': forms.TextInput(attrs={'class':'form-control'}),
        'author': forms.TextInput(attrs={'class':'form-control'}),
        'price': forms.TextInput(attrs={'class':'form-control'}),
        'pages': forms.TextInput(attrs={'class':'form-control'}),
        'book_type': forms.TextInput(attrs={'class':'form-control'}),
    }
