我尝试在同一视图中使用两个formset_factory和django动态表单集,但我收到此错误 [DOM]找到2个具有非唯一ID的元素#id_form-TOTAL_FORMS: 当我尝试在第二个表单上添加前缀时,它只生成一个id,然后如果添加多个项目,它将保存最后一个项目。 我想知道如何解决这个问题以及它为什么会发生? 提前谢谢。
my forms.py
class ResearchLineForm(forms.ModelForm):
class Meta:
model = ResearchLines
fields = ('title', )
widgets = {
'title':forms.TextInput(attrs={
'class':'form-control',
'placeholder':'Linhas de Pesquisa'
})
}
LinesFormSet = formset_factory(ResearchLineForm)
class TokenForm(forms.Form):
name = forms.CharField( max_length=255, widget=forms.TextInput(
attrs={
'class':'form-control',
'placeholder':'Linhas de Pesquisa'
})
)
email = forms.CharField(max_length=255, widget=forms.TextInput(

'placeholder':'Linhas de Pesquisa'

formsets使用#id_form-TOTAL_FORMS(和其他一些东西)来查看有多少表单并且最初是。
如果您想在一个页面上显示多个表单集,那么您将遇到问题,即您最终得到两个具有相同ID的对象。要解决此问题,您可以为一个(或两个)表单集定义prefix。
