CheckboxSelectMultiple can not show the data on the view

CheckboxSelectMultiple can not show the data on the view.

when the form use CheckboxSelectMultiple, it can not show the data on view.

problem code :

class CheckboxSelectMultiple(SelectMultiple):
    def render(self, name, value, attrs=None, choices=()):
        if value is None: value = []
        has_id = attrs and 'id' in attrs
        final_attrs = self.build_attrs(attrs, name=name)
        output = [u'<ul>']
        # Normalize to strings
        str_values = set([force_unicode(v) for v in value])

solution:

 str_values = set([force_unicode(v) for v in '''eval'''(value)])

I've reformatted your description -- next time please use preview to make sure your code samples display correctly.

Using eval() is potentially dangerous as maliciously code could get executed. It is unclear what problem you're having. Please reopen this ticket if you can provide a clear example or a test case illustrating the problem that you're trying to solve.

Reopening so that this ticket can be reviewed again (I don't have time to do it just now).

I had a look at your attached code and as I can see you missing the initial option.

You can use initial to select values on a choice field like this:

gender = forms.MultipleChoiceField(initial=['m'],required=False, widget=CheckboxSelectMultiple, choices=(('m', 'Male'), ('f', 'Female')))

this generates in the view:

u'<p>Gender: <ul>\n<li><label><input checked="checked" type="checkbox" name="gender" value="m" /> Male</label></li>\n<li><label><input type="checkbox" name="gender" value="f" /> Female</label></li>\n</ul></p>'

hope this helps!

I think you did not catch what i meen.
When you submit your form, the release version can not keep the selected option.
If the choice is (('m', 'Male'), ('f', 'Female')), the realse version will work.
If the choices is (('male', 'Male'), ('female', 'Female')), the realse version will not work.

Please submit the form, you will see the problem.
