forms

# 角色的form
class RoleForm(forms.ModelForm):
    class Meta:
        model = models.Role
        fields = '__all__'
        exclude = ['permissions']
        widgets = {
            'name':forms.TextInput(attrs={'class':'form-control'}),
        }

　　

 

后端

# 角色添加/编辑
def role_change(request, edit_id=None):
    obj = models.Role.objects.filter(pk=edit_id).first()

    form_obj = RoleForm(instance=obj)

    title = '添加角色信息' if not obj else '编辑角色信息'

    if request.method == 'POST':
        form_obj = RoleForm(request.POST, instance=obj)
        if form_obj.is_valid():
            form_obj.save()

            return redirect(reverse('role_list'))

    return render(request, 'rbac/forms.html', {'form_obj': form_obj, 'title': title})
