当尝试使用WTForms设置SelectField的默认值时,我将值传递给'default'参数,就像这样.

class TestForm(Form):
  test_field = SelectField("Test: ", choices=[(1, "Abc"), (2, "Def")], default=2)

我也试过以下.

class TestForm(Form):
  test_field = SelectField("Test: ", choices=[(1, "Abc"), (2, "Def")], default=(2, "Def"))

既不将默认的选定字段设置为"Def".这适用于其他类型的字段,如TextField.如何设置SelectField的默认值？'
