Python 在dhangoforms中隐藏从模型生成的字段并将其保存在数据库中

1] 我有以下型号：

class UserReportedData(db.Model):
  #country selected by the user, this will also populate the drop down list on the html page
  country = db.StringProperty(default='Afghanistan',choices=['Afghanistan'])
  #city selected by the user
  city = db.StringProperty()
  user_reported_boolean = db.BooleanProperty() # value that needs to be hidden from the display 
  date = db.DateTimeProperty(auto_now_add=True)

class UserReportedDataForm(djangoforms.ModelForm):

  class Meta:
    model = UserReportedData

2] 决定布尔值“user\u reported\u boolean”的html代码如下所示

 '<input type="submit" name="report_up" value= "Report Up">'
 '<input type="submit" name="report_down" value= "Report Down">'

class UserReporting(webapp.RequestHandler):

  def post(self):
    #get the data that the user put in the django form UserReportForm
    data = UserReportedDataForm(data=self.request.POST)

    #need to find whether user hit the button with the name "report_up" or "report_down"
    # this is not working either
    if 'report_up' in self.request.POST:
        data.user_reported_boolean = True
    elif 'report_down' in self.request.POST:
        data.user_reported_boolean = False    

    if data.is_valid():
        # Save the data, and redirect to the view page
        entity = data.save(commit=False)
        entity.put()
        self.redirect('/')

问题:

1] 如何隐藏字段“user\u reported\u boolean”不显示在html表单上

2] 如何在数据库中保存此字段“user\u reported\u boolean”

1：从模型表单中排除此字段。 2：在未保存的模型实例中，您可以通过

commit=False

您希望字段处于表单中，但在显示时隐藏，还是不希望它处于表单中？@anand，是的，我希望字段“user\u reported\u boolean”出现在模型中，但不希望显示。@anand，我尝试了下面@Yuji Tomita给出的响应，并成功地从html页面中隐藏了模型中的一个字段。谢谢@Yuji Tomita，这很有效。再次感谢您的详细回复

class MyModelForm(ModelForm):
    class Meta:
         model = Foo
         exclude = ('myfield',)

entity = data.save(commit=False)
entity.user_reported_boolean = True # False, whatever.
entity.save()
