Django 添加 CSS 到 InlineFormSet
Django Add CSS to InlineFormSet
我正在尝试将一些 CSS 数据添加到我创建的内联表单集中。我以前对常规 ModelForms
做过,但它不适用于内联表单集。
这里是习俗__init__
:
class CustomSubIFormset(BaseInlineFormSet):
def __init__(self, *args, **kwargs):
super(CustomSubIFormset, self).__init__(*args, **kwargs)
self.forms.widget.attrs.update({'placeholder': 'User Name'})
for name, forms in self.forms.items():
forms.widget.attrs.update({'class': 'form-control'})
views.py
中的通话
subIFormSet = inlineformset_factory(Study, SubInvestigator, fields=('name',), extra=4, formset=CustomSubIFormset)
错误信息是'list'
对象没有属性'widget'
。回溯:
Traceback:

56. self.forms.widget.attrs.update({'placeholder': 'User Name'})
Exception Type: AttributeError at /studies/create-study/
Exception Value: 'list' object has no attribute 'widget'
试试这个:
for form in self.forms:
for field in form.fields:
field.widget.attrs.update({'class': 'form-control'})
