swagger-codegen-v3 mustache files custom templating not working for python-flask

Question

I am trying to use custom templates on my swagger server code generated by swagger-codegen-v3 docker image. I am using an already validated yaml file as source, a trimmed version of pet-store sample.

I downloaded all mustache files from swagger-codegen/src/main/resources/flaskConnexion/* in master branch. I took a look at v3.0.0 branch but no mustache files there.

Running generate docker run --rm -v $(pwd):/local swaggerapi/swagger-codegen-cli-v3 generate -i /local/openapi.yaml -l python-flask -o /local/out/python -t /local/custom_templates/

I am getting this error message:

Exception in thread "Thread-1" java.lang.RuntimeException: Could not generate model 'Address'

    {{name}} = {{{value}}}{{^-last}}

Where are the right mustache files for python-flask?

Answer 1

swagger-codegen-v3 mustache files are in another repository:

https://github.com/swagger-api/swagger-codegen-generators/

Download master version:

git clone --depth=1 https://github.com/swagger-api/swagger-codegen-generators.git

Go to mustache(Handlebars) files for Python and Flask:

cd swagger-codegen-generators/src/main/resources/handlebars/pythonFlaskConnexion/
