form不能和添加的form一样 ===》 多一个id字段 用于判断更新哪条数据==》在前端渲染时隐藏id字段（不能让用户选择） forms.HiddenInput
class UpdateMultiPermissionForm(forms.Form): id = forms.IntegerField( widget=forms.HiddenInput(attrs={‘class‘: ‘form-control‘}) ########新增加id字段 并且设置隐藏 ) title = forms.CharField( widget=forms.TextInput(attrs={‘class‘:‘form-control‘}) ) url = forms.CharField( widget=forms.TextInput(attrs={‘class‘: ‘form-control‘}) ) name = forms.CharField( widget=forms.TextInput(attrs={‘class‘:‘form-control‘}) ) menu_id = forms.ChoiceField( choices=[(None,‘------------‘)], widget=forms.Select(attrs={‘class‘: ‘form-control‘}), required = False ) pid_id = forms.ChoiceField( choices=[(None, ‘-----------‘)], widget=forms.Select(attrs={‘class‘: ‘form-control‘}), required=False ) def __init__(self,*args,**kwargs): super().__init__(*args,**kwargs) self.fields[‘menu_id‘].choices += Menu.objects.values_list(‘id‘,‘title‘) self.fields[‘pid_id‘].choices += Permission.objects.filter(pid__isnull=True).exclude( menu__isnull = True ).values_list(‘id‘,‘title‘)
{% for field in form %} #########第一个的话就不生成td 页面不会错开
{% if forloop.first %}
{{ field }}
{% else %}
<td>{{ field }}<span style="color: red;float: right">{{ field.errors.0 }}</span></td>
{% endif %}
{% endfor %}
因为了id字段 所以后端传值要 加上id,然后用id来数据更新
formset = form_class(initial=[{‘id‘:1,‘title‘:‘xi‘,‘url‘:‘xxx‘}]) ##models.Permission,objects.all().values(xxx,xx,xx)
def multi_edit(request): form_class = formset_factory(UpdateMultiPermissionForm,extra=0)################## if request.method == ‘GET‘: formset = form_class(initial=Permission.objects.all().values(‘id‘,‘title‘,‘url‘,‘name‘,‘menu_id‘,‘pid_id‘)) return render(request, ‘multi_edit.html‘, locals()) formset = form_class(data=request.POST) if formset.is_valid(): post_row_list = formset.cleaned_data for i in range(0, formset.total_form_count()): try: Permission.objects.filter(id=post_row_list[i].get(‘id‘)).update(**post_row_list[i]) except Exception as e: pass else: return render(request, ‘multi_edit.html‘, locals()) return render(request, ‘multi_edit.html‘, locals())
