wtforms Form class subclassing and field ordering

Question

I have a UserForm class:

class UserForm(Form):
    first_name = TextField(u\'First name\', [validators.Required()])
    last_name = TextField(u\'Last name\', [va         


        

Answer 1

I have combined two answers into following snippet:

def __iter__(self):
    ordered_fields = collections.OrderedDict()

    for name in getattr(self, 'field_order', []):
        ordered_fields[name] = self._fields.pop(name)

    ordered_fields.update(self._fields)

    self._fields = ordered_fields

    return super(BaseForm, self).__iter__()

It's iter on BaseForm that each of my form is child of. Basically everything that is defined in field_order goes in that order, rest of the fields are rendered as-is.
