为什么我们需要 Django 表单中 Meta class 中的字段值?
Why do we need fields value in Meta class in Django forms?
如果我的表单 class 中有 3 个字段,而在 fields
中我只设置了一个字段,在我的 html 页面上仍然是 3 个字段。
示例:
class CategoryForm(forms.ModelForm):
name = forms.CharField(max_length=128,
help_text='Please enter the category name.')
views = forms.IntegerField(initial=0)
likes = forms.IntegerField(initial=0)
slug = forms.CharField(widget=forms.HiddenInput(), initial=0)
class Meta:
model = Category
fields = ('name',)
所以 fields
变量没有隐藏任何东西?
"The generated Form class will have a form field for every model field specified, in the order specified in the fields attribute."
如果要隐藏字段,请使用
exclude = ('views','likes','slug')
我强烈建议您看一下文档:
