在 django ModelForm 中动态添加字段

Question

我的模型

class MyModel(models.Model):
    remark = models.CharField(max_length=120)
    data_1 = models.BooleanField(default=False)
    data_2 = models.BooleanField(default=False)
    data_3 = models.BooleanField(default=False)
    data_4 = models.BooleanField(default=False)

表格

class MyModelForm(forms.ModelForm):
    CHOICES= (("data_1", "data_1"),
               ("data_2", "data_2"),
               ("data_3", "data_3"),
               ("data_4", "data_4"),)
    my_choice = forms.MultipleChoiceField(choices=CHOICES, widget=forms.CheckboxSelectMultiple())
    class Meta:
        model = MyModel
        fields = ["remark"]

查看

class MyView(UpdateView):
    model = MyModel
    form_class = MyModelForm
    template_name = "mytemplate.html"

    def form_valid(self, form):
        selected_choices = self.request.POST.getlist("my_choice")
        for item in selected_choices:
            form.instance.item = False
        form.instance.remarks = form.cleaned_data["remark"]
        form.instance.save()
        return super(MyView, self).form_valid(form)

我想要的是，我想通过选中复选框来选择选定的选项并将其值更改为 False，剩下的必须是 unaffected.Please 帮助....

这道题比较难懂，好像跟表单加字段没什么关系。但是我认为你正在寻找setattr:

    for item in selected_choices:
        setattr(form.instance, item, False)
