Repo to illustrate flasgger validation issues

(Built with Python 3.6, on MacOS.)

This is attempting to show that the validation=True option on the swag_from decorator isn't doing anything, and the validate() call (which IS doing something) doesn't like following Swagger's allOf option.

The Swagger definition is an entity called Bar, which pulls in fields from FooMixin. I can't get validation=True to fail validation at all, and calling validate() fails if Bar's fields are all correct, as it can't find FooMixin.

Steps to reproduce environment

1. Pull this repo :-) and go to repo directory in terminal
2. virtualenv -p python3 venv
3. source venv/bin/activate
4. pip install -r requirements.txt
5. python -m flasgger_broken

Tests to run

With validation=True, valid data produces correct response

$ curl -X POST -H "Content-Type: application/json" -d '{ "bar_uuid": "uuid1234", "bar_email": "rob@rob.com", "foo1": "I make it valid", "foo2": "something" }' http://localhost:5000/bar

{
  "message": "it worked!"
}

---

With validation=True, invalid data produces wrong response

$ curl -X POST -H "Content-Type: application/json" -d '{ "iaminvalid": "hahaha" }' http://localhost:5000/bar
{
  "message": "it worked!"
}

---

With validate(), direct invalid data produces correct response

$ curl -X POST -H "Content-Type: application/json" -d '{ "bar_uuid": "uuid1234", "bar_email": "rob@rob.com" }' http://localhost:5000/bar_manual
'foo2' is a required property

Failed validating 'required' in schema:
    {'allOf': [{'$ref': '#/definitions/FooMixin'}],

     'example': {'bar_email': 'me@email.com',
                 'bar_uuid': '1ab091c8-7567-4420-ab01-5427c991ef2f',

With validate(), inherited invalid data produces wrong response (should say foo1 is required, as FooMixin needs it)

$ curl -X POST -H "Content-Type: application/json" -d '{ "bar_uuid": "uuid1234", "bar_email": "rob@rob.com", "foo2": "something" }' http://localhost:5000/bar_manual
