Accessing a method in rails controller via button/link - ruby-on-rails

Question

I was trying to follow the solution on this thread - Rails 3 link or button that executes action in controller
I defined :update_question in my routes.rb file:
resources :surveys do
put :update_question, :on => :member
end
and in my controller:
class SurveysController < ApplicationController
before_action :set_survey, only: [:show, :edit, :update, :destroy]
before_action :set_question
# GET /surveys
# GET /surveys.json
def index
#surveys = Survey.all
end
# GET /surveys/1
# GET /surveys/1.json
def show
end
def survey
#survey = Survey.find(params[:survey_id])
end
# GET /surveys/new
def new
#survey = Survey.new
end
# GET /surveys/1/edit
def edit
end
def update_question
flash[:alert] = "getting there man"
end
And listed the link here in the html:
<%= link_to "Next Question", update_question_survey_path(#survey), {:method => :put} %>
However when I click the link I get this error:
Template is missing
Missing template surveys/update_question, application/update_question with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}.
Which seems to elude that it's looking for a view - but really I just want it to run the method in my survey controller and update the question that's being displayed. Perhaps I'm going about this the wrong way, any help/suggestions is much appreciated!

Answer 1

That's because the action is correctly reached, but then Rails tries to render something. By default, it will look for a view file with the same name of the action.
You should do something like this:
def update_question
set_survey
# do stuff
flash[:alert] = "getting there man"
redirect_to survey_path(#survey)
end
