Model form generator now accepts wtf custom 'validators' and 'filters' on model field definition.

[losintikfos]

Added a wrapper sub-class WtfBaseField to allow additional WTForm field parameters and settings needed by flask-mongoengine, without necessarily going through to the core mongoengine BaseField.

• flask_mongoengine/__init__.py has patching to redirect wtf mongoengine Fields of base BaseField to use WtfBaseField
• wtf/orm.py now has 'validators' and 'filters' allowed on behalf wtf model field generator.

Example:

 class Contact(db.Document)
    telephone = db.StringField(
        required=True,
        validators=[
          validators.InputRequired(message=u'Missing telephone.'),
        ],
        max_length=50
    )

Hi @rozza,

Do you have a timeline for this merge. Do you want me to do anything to get it accepted. I do believe it will resolve some the current tickets and also as an added feature.

Hi @rozza,

Are there active maintainers for this project? I was also wondering when possibly push request #147 will be considered?

Thanks

[rozza]

@losintikfos I'm really sorry I don't have the bandwidth - but I have invited you to the organisation - so feel free to check the build and merge :)

@rozza Thanks

@losintikfos seems what you broke something.
When I am trying to use version from repo I get following error:

@dizballanze thanks for reporting this - I am having a quick look into this.

[losintikfos]

@dizballanze update your local version with the fix and try again - thanks.

[dizballanze]

@losintikfos problem solved - thanks! 😸

[losintikfos]

Hi @dizballanze, I just pushed a fix to handle both validators and filters. Can you please update your version and confirm it still works fine.

Thanks

[dizballanze]

@losintikfos I have checked, it still works.

[losintikfos]

@dizballanze Thanks.
