How to send simple json response in Rails?

Question

I need to send json response depends on user entered data in input, but I\'m failing to send simple json request.

I followed this article - http://paydrotalks.com/po

Answer 1

One Simple way is:

def my_action 

 render :json => {:name => "any name"}

end

Answer 2

I usually use this method to return json data:

msg = {:token => token, :courseId => courseId}
render :json => msg

Answer 3

Not sure about dealing with custom MIME, but as for rendering JSON, this should work:

def testme
  respond_to do |format|
    msg = { :status => "ok", :message => "Success!", :html => "<b>...</b>" }
    format.json  { render :json => msg } # don't do msg.to_json
  end
end

Also it might help if you state which version of Ruby and Rails you are using.

Answer 4

The simplest way is render json: {foo: 'bar'}
