在django formset中只读字段

问题描述

我正在使用modelformset factory从模型字段中生成formset。在这里，我只想将查询对象作为只读方式和其他（额外的形式）作为非readonly字段

I'm using modelformset factory to generate formset from model fields. Here i want to make only the queryset objects as readonly and other (extra forms) as non readonly fields

我如何实现？

  AuthotFormSet = modelformset_factory(Author, extra=2,)
  formset = AuthorFormSet(queryset=Author.objects.all())

在上面的表单集中，我想显示所有的查询对象为只读，剩余额外的表单为非唯读字段。

In Above formset i wanted to display all the queryset objects as readonly, and remaining extra forms as non readonly fields. How can i achive this?

如果我使用，

      for form in formset.forms:
          form.fields['weight'].widget.attrs['readonly'] = True

这将把所有的表单（包括额外的）字段转换为只读，我不想要的。
我也使用jquery插件将形式动态地添加到formset

This will convert all the forms (including extra) fields to readonly which i dont want.And also i'm using jquery plugin to add form dynamically to the formset

推荐答案

我建议指定一个表单用于模型，在这种形式中，您可以设置任何您想要阅读的属性。

I'd recommend specifying a form to use for the model, and in that form you can set whatever attributes you want to read only.

#forms.py
class AuthorForm(forms.ModelForm):
    class Meta:
        model = Author

    def __init__(self, *args, **kwargs):
        super(AuthorForm, self).__init__(*args, **kwargs)
        if self.instance.id:
            self.fields['weight'].widget.attrs['readonly'] = True

#views.py
AuthorFormSet = modelformset_factory(Author, extra=2, form=AuthorForm)
