form_choices "not a valid choice"

    form_choices = {'pref1': [(1, 'Offensive Lineman'), (2, 'Wide Receiver'), (3, 'Offensive Lineman OR Wide Receiver')],
        'pref2': [(1, 'Yes'), (2, 'No'), (3, 'Depends')], 'pref3': [(1, 'Yes'), (2, 'No')],
        'pref4': [(1, 'Yes'), (2, 'No')], 'timezone': [(1, 'EST'), (2, 'CST'), (3, 'PST'), (4, 'Europe')],
        'role': [(2, 'QB'), (1, 'Veteran'), (0, 'Rookie'),]}

They are ints in the database, so I’m not sure why it isn’t working when trying to change any of these form values.

Well, it can be achieved via form_args property, see below:

First import:

from wtforms.fields import SelectField

Then override field and map your form field:

form_overrides = dict(active=SelectField)
form_args = dict(
    active=dict(choices=[(0, 'No'), (1, 'Yes')], coerce=int)
)

Also, if you want to alias your column in listing then do the following:

column_choices = {'active': [
    (0, 'No'),
    (1, 'Yes'),
]}

I had this bug as well. It’s because the values coming back from the form are strings (like "1") not integers.

I’m not sure if my solution is the best one - I think there are probably alternatives, but here’s what I did: I overrode the validate_form method to cast the value I needed (to avoid the error). I also had to override the on_form_prefill method to do the reverse conversion - otherwise the selected option wasn’t pre-selected in the drop-down on the edit form.

Here’s an adapted example for a field called pref1. You’d need to extend this to handle all the fields in your code sample, @ToastyBiggums.

class MyView(ModelView):
    # Ensure the pref1 is an int before validating
    # Avoids 'Not a valid choice' error
    def validate_form(self, form):
        form.pref1.data = int(form.status.data)
        return super(MyView, self).validate_form(form)

    # And do the reverse when loading the edit form so the right
    # option is pre-selected
    def on_form_prefill(self, form, id):
        form.pref1.data = str(form.pref1.data)  # in Python 2, use the unicode function instead
