Hi,
I have checkbox group (checkboxes with same name) in my form
categoryForm = form.Form(
#other form elements here
form.Checkbox('categories', value='cat1'),
form.Checkbox('categories', value='cat2'),
form.Checkbox('categories', value='cat3'),)
and handle it in class like this
data = web.input(categories=[])
frmCategory = categoryForm()if not frmCategory.validates(data):
return frmCategory.render()
I have checked checkboxes' values as list and send them form's validate
function as source data but it fails when it checks checkbox's validation.
The problem is Checkbox class's set_value() function. It sets checked
property with bool(value). In this situation value is a list which has
checked checkboxes' values but not unchecked ones. However it renders as
checked also unchecked checkboxes after (failed)validation. I built this[1]
patch to handle this. How do you handle this?
