我写了自定义FieldList
:
class EventForm(Form):
enabled = BooleanField()
user_role = IntegerField()
class EventsForm(Form):
user_roles = FieldList(FormField(EventForm))
section_name = StringField()
class CompanyForm(BaseForm):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self._populate_event_permissions()
def _populate_event_permissions(self):
permissions = get_all_event_permissions()
for event, value in permissions.items():
form_field = self.event.append_entry(
data={'section_name': event})
field_1 = form_field.user_roles.append_entry(
data={'enabled': True, 'user_role': 8})
field_1.enabled.label.text = 'Participant'
field_1.enabled.name = value
field_2 = form_field.user_roles.append_entry(
data={'user_role': 9})
field_2.enabled.label.text = 'Organizer'
field_2.enabled.name = value
field_3 = form_field.user_roles.append_entry(
data={'user_role': 10})
field_3.enabled.label.text = 'Admin'
field_3.enabled.name = value
在模板中很好地呈现了它,但是每次我尝试发送它并且复选框为False
时,它总是像在True
中一样发送append_entry
。这是我检查输入数据的方法。
class MyView(BaseModelView):
def on_model_change(self, form, model, is_created):
for section in form.event.entries:
for entry in section.user_roles.entries:
print(entry.enabled.data)
无论复选框是True还是False,看来表单总是发送default value
我也定义了表单预填充,并且如果我手动将数据库中的值设置为False,它会正确地将输入呈现为False,但是当我发送时再次使用该表单(无论处于何种复选框状态),都将数据库覆盖为True。绝对存在表单看不到已编辑值的问题。我该怎么解决?

您正在表单本身的init方法中设置表单字段的值。在加载相关视图时,这很可能会覆盖request.form
在表单上设置的值。
您应该根据需要在scaffold_form()
或create_form()
/ edit_form()
中填充字段。
class MyView(BaseModelView):
def scaffold_form(self):
form = super(MyView, self).scaffold_form()
permissions = get_all_event_permissions()
for event, value in permissions.items():
form_field = self.event.append_entry(data={'section_name': event})
# etc.
return form
