This library demonstrates how to use the Liberator library to create controllers that respect the HTTP specificiation.
Check out the file at
for an example of a controller using Liberator to pass Phoenix's generated controller tests.
This project was built using Phoenix generators. First, a new Phoenix project was created.
mix phx.new liberator_example --no-webpack --no-html
Then, in that project, we generated the
LiberatorExample.Blog context, with a
This generates a controller and an associated test module.
mix phx.gen.context Blog Post posts title:string content:string
We also added the associated
resources directive to
scope "/api", LiberatorExampleWeb do pipe_through :api # You can use `Phoenix.Router.resources/4` with a Liberator resource. resources "/posts", PostController, except: [:new, :edit] end
However, we then deleted the contents of
LiberatorExampleWeb.PostController and replaced with a Liberator resource module.
Just enough functionality was added to the resource module to make the existing controller tests pass.
Questions and pull requests are more than welcome. I follow Elixir's tenet of bad documentation being a bug, so if anything is unclear, please let me know in our mailing list! Ideally, my answer to your question will be in an update to the docs.
