Question

我有一个表单，我希望用户选择一个级别。但是，我的模型提出的问题是解包的价值太多了。

我试图将列表中所需的选项放入我之前发现的选项中，但出于某种原因，这次它不会工作。

模型I尝试访问：

class Status(models.Model):
    status_level=models.CharField(max_length=15)

    def __str__(self):
        return self.status_level
    def __iter__(self):
        return iter(self.status_level)

表单本身：

FLAG_CHECKBOX = [（＆＃39;有源＆＃39;＆＃39;主动＆＃39），（＆＃39;不活动的＆＃39;＆＃39;无效＆＃39;），] STATUS_CHECKBOX = [（Status.objects.all（）），]

class Add_Event_Form(forms.ModelForm):

    event_title=forms.CharField(max_length=50,help_text="Please enter an informative title.")
    event_status=forms.MultipleChoiceField(choices=STATUS_CHECKBOX,widget=forms.CheckboxSelectMultiple,help_text="Please select the status of the event")
    event_description=forms.CharField(max_length=500, initial="", help_text="Enter a short description of the event here")
    event_flag=forms.MultipleChoiceField(choices=FLAG_CHECKBOX,required=True,widget=forms.CheckboxSelectMultiple,help_text="Please select the status of this event.")
    date_active=forms.DateField(required=True, widget=forms.DateInput(attrs={'class':'datepicker'}), help_text="Please select a date for this event.")
    time_active=forms.TimeField(required=True, widget=forms.TimeInput(format='%HH:%MM'), help_text="Please select a time for this event.")

标记错误发生位置的行：

H:\interview\server_status\views.py in add_event
    return render(request,'server_status/add_event.html',{'form':form}) 

        return self.get_renderer(name, value, attrs, choices).render() ...
