Combine params.required with apipie param_group

Question

How can I combine Rails' params.require with apiepie's param_group to avoid duplication?

Answer 1

I know that it's a little bit late to reply, but here's how to do it:

1. Create a controller that extends ApiPie:

class ApiController < ActionController::Base extend Apipie::DSL::Concern

2. Define param_groups in that controller:

def_param_group :param_errors do
    error code: 200, desc: "Success"
    error code: 400, desc: "Error"
    error code: 401, desc: "Unauthorized"
    error code: 404, desc: "Not Found"
end

3. Extend this controller from your second controller:

class MyCustomController < ApiController

4. Call the param_group before your function using:

param_group :param_errors, ApiController
def my_method
    # ...
end
