问题描述
我正在使用WTForms，并且试图显示SelectField，但是出现以下错误:
I'm using WTForms and I'm trying to display a SelectField, but I get the following error:
>>> form.status()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python26\Lib\site-packages\wtforms\fields.py", line 136, in __call__
return self.widget(self, **kwargs)
File "C:\Python26\Lib\site-packages\wtforms\widgets.py", line 237, in __call__
for val, label, selected in field.iter_choices():
File "C:\Python26\Lib\site-packages\wtforms\fields.py", line 390, in iter_choices
for value, label in self.choices:
ValueError: too many values to unpack
这是我的表格:
class TestForm(Form):
status = SelectField(u'Status', choices=Test.statuses())
Test.statuses静态方法返回字符串列表.我在做什么错了?
The Test.statuses static method returns a list of strings. What am I doing wrong?
推荐答案
它需要一个(str, str)元组的列表，而不是字符串的列表.
It expects a list of (str, str) tuples, not a list of strings.
