Hello,
I've changed my database from postgresql to mysql. I have never used
mysql in django projects before, so it was surprising to me when i saw
0/1 values instead of True/False in boolean fields. It wasn't an issue
until i upgraded django from 1.3.1 to 1.4b. After that, all boolean
fields in admin interface are checked (in edit mode). They are rendered as:
<input type="checkbox" id="id_checkbox_filter" value="0"
name="checkbox_filter" checked="checked">
i've looked into forms.widgets.CheckboxInput in both django versions and
noticed some logic changes when checking value:
(1.3.1)
def __init__(self, attrs=None, check_test=bool):
super(CheckboxInput, self).__init__(attrs)
# check_test is a callable that takes a value and returns True
# if the checkbox should be checked for that value.
self.check_test = check_test
(1.4b)
def __init__(self, attrs=None, check_test=None):
super(CheckboxInput, self).__init__(attrs)
# check_test is a callable that takes a value and returns True
# if the checkbox should be checked for that value.
if check_test is None:
self.check_test = lambda v: not (v is False or v is None
or v == '')
else:
self.check_test = check_test
in this case "0" is treated as True.
Is this a bug?
regards,
