Could you please add a license? Preferably MIT or similar? I'd love to be able to simply grab this and go for new projects, but for a variety of reasons, I can't do that without a license in place.

Get an error like this don't know what todo. Any idea ?

I follow the steps in this article to setup demo application, but there is an error raised.

After investigation,
This error can be fixed by downgrading Werkzeug to version 0.16.0.

requirements.txt (before downgrading)
flask-restplus==0.9.2
Flask-SQLAlchemy==2.1

requirements.txt (after downgrading)
flask-restplus==0.9.2

When writing unittest,
from app import app
test_app = app.test_client()

but initialize_app and other functions not working.
How we can write unittest for your architecture.

The generated Swagger schema fails validation. (Attached a copy as swagger.yaml for reference)

Putting http://localhost:8888/api/swagger.json into http://editor.swagger.io/ generates these errors:

Errors

 Semantic error at paths./blog/posts/archive/{year}/{month}/.get.operationId
operationIds must be unique
- Semantic error at paths./blog/posts/archive/{year}/{month}/{day}/.get.operationId
operationIds must be unique
- Schema error at responses.NoResultFound
requires property "description"

swagger_spec_validator, used by other swagger tools, only seems to fails on this exception:

import swagger_spec_validator
swagger_spec_validator.validate_spec_url('http://localhost:8888/api/swagger.json')

raises exception:

SwaggerValidationError: 'description' is a required property
...
On instance['responses']['NoResultFound']:

swagger.yaml.txt

When trying to click on an operation (for example "get posts") Swagger is not able to expand the details, but seems to try to open an non-existant URL: http://localhost:8888/api/#!/blog%2Fposts/get_posts_collection

Hi, Thank you for program, but i have a problem, i want to deploy in server but i am not sure what configuration i to do, can you help please.

Hi! I'm following this tutorial but I have a problem with the API pagination. Although the pagination data is appearing, the data fields don't. Do you have any idea what I can do?

My code:

flatdata_fields = api.model('Mutations', {
    'id': fields.Integer(readOnly=True),
    'mutation_code': fields.String(required=True),
    'pdb_mutant': fields.String,
    'pdbs_template': fields.String,
    'mutated_chain': fields.String,
    'mutation_type': fields.String,
    'mut_count': fields.Integer,
})

pagination = api.model('A page of results', {
    'total': fields.Integer(),
    'page': fields.Integer(),
    'per_page': fields.Integer(),
})

page_of_flatdata = api.inherit('Page of Mutation data', pagination, {
    'rows': fields.List(fields.Nested(flatdata_fields))
})

@td.route('/')
class rawThermDataList(Resource):
    @api.expect(pagination_arguments)
    @api.marshal_with(page_of_flatdata)
    def get(self):
        args = pagination_arguments.parse_args(request)
        page = args.get('page', 1)
        per_page = args.get('per_page', 10)
        return FlatData.query.paginate(page, per_page, error_out=False)

Thank you!

Hello,
I wanted to run your sample code, but apparently I can't import the root packet.
