Looks like this is the same problem of #102

I am going to write some tests for it and then merge your PR..

Thanks

[rochacbruno]

Steps needed to test this

• Create a installable package with api definitions
• Put that package to be installed by travis (make test should ensure that)
• Create examples/test_package.py with an app using that package
• Check if addresses Import feature misidentifies root path for endpoint #102 problem

@talitarossari still need help to reproduce the error.

Take a look at etc/flasgger_package and tests/package_example

Can you reproduce your case there?

[talitarossari]

@rochacbruno, sorry for waiting.
I was able to reproduce my situation (import the .yml from an external package).
For this, I needed to create another file "parameters.yml" and import it out of the package.
The error did not persist.

I found this issue thru the comment in flasgger/utils.py line 466 while im following the stack trace error.

I had an issue importing .yml files using swag_from() from different directory.
I found out that it changes the path or retrieving the .yml files from another directory.
In my case the .yml file directory became relative_path/utils/path_to_swagger/my.yml instead of relative_path/path_to_swagger/my.yml

to fix this issue on my end, I define the relative path of my .yml documentation.

# because my swagger docs is the same path as my api module.
BASE_SWAGGER_DOCS_PATH = os.path.dirname(__file__) + '/docs/swagger'`

@swag_from('%s/my.yml' % BASE_SWAGGER_DOCS_PATH)
