respond_with in Rails 5 API-only app (and responder gem) always returns blank

Question

Has anyone else come across this? I'm writing a Rails API in Rails 5 ( 5.0.0.beta2 ), and have included the responder gem so as to be able to use respond_with , and put respond_to :json in the controller, but no matter what I pass to respond_with (eg respond_with @collection ), the response is always blank. Anyone know why this might happen?

Answer 1

responders 2.1.2包括对ActionController::API的修复，更新您的应用

Answer 2

have you tried responding in the controller with something like:

render :json => { data: "Success!" }

or if you're in a respond_to block, something like:

format.json { render json: "Success!" }

steps: 1. add to gemfile gem 'responder', '~> 2.0'

2. rails generate responder:install

3. rails generate scaffold ....

4. I suggest running rake db:drop. db:create then rake db:migrate (I am pretty early on in my app so my database wasnt something i was concerned about deleting and re-creating)

5. It worked for me after I included the gemfiles before i created the scaffold hope this helps
