In the wtform docuentation the following function is described as a widget that can render a SelectMultipleField as a collection of checkboxes:
def select_multi_checkbox(field, ul_class='', **kwargs): kwargs.setdefault('type', 'checkbox') field_id = kwargs.pop('id', field.id) html = [u'<ul %s>' % html_params(id=field_id, class_=ul_class)] for value, label, checked in field.iter_choices(): choice_id = u'%s-%s' % (field_id, value) options = dict(kwargs, name=field.name, value=value, id=choice_id) if checked: options['checked'] = 'checked' html.append(u'<li><input %s /> ' % html_params(**options)) html.append(u'<label for="%s">%s</label></li>' % (field_id, label)) html.append(u'</ul>') return u''.join(html) I am trying to actually use this as an example to see what it looks like in one of my forms. However I am having some trouble and I am not sure how to call it since I am only used to using the default fields. This is what I have tried:
class myForm(FlaskForm): my_choices = [('1', 'Choice1'), ('2', 'Choice2'), ('3', 'Choice3')] my_multi_select = SelectMultipleField(choices = my_choices,id='Test') my_checkbox_multi_select = select_multi_checkbox(my_multi_select) This gives me the following error:
line 52, in select_multi_checkbox field_id = kwargs.pop('id', field.id) AttributeError: 'UnboundField' object has no attribute 'id' My next iteration was this:
my_checkbox_multi_select = select_multi_checkbox(SelectMultipleField,ul_class='',choices=my_choices,id='test') This also gave me an error with the id attribute but the field wasn't Unbounded anymore.
line 52, in select_multi_checkbox field_id = kwargs.pop('id', field.id) AttributeError: type object 'SelectMultipleField' has no attribute 'id' I was wondering what the proper way to implement this is. I see that it is a function so I thought that it needed to be called on a field but I wasn't sure what I was doing wrong.
