NoMethodError in EventsController#create: undefined method `event_url'

i'm trying to set up a way to create new events in my Rails app. However, when I go to the correct page (according to my routes) in order to make a new event, I get this error:

NoMethodError in EventsController#create 
undefined method `event_url for #<EventsController:0x000000035a9dc8>

This is the relevant area (line 23):

  21 respond_to do |format|
  22 if @event.save
  23 format.html { redirect_to @event, notice: 'Event was successfully created.' }
  24 format.json { render :show, event: :created, location: @event }
  else
  25 format.html { render :new }

This is what my server log says when I try to load the page:

Started GET "/create_event" for 12.43.117.2 at 2015-04-17 15:59:57 +0000

I have Ruby on Rails 4, devise, and simple_form installed. Any help would be much appreciated.

When you use redirect_to with an object in Rails, it will attempt to redirect you to the appropriate show action for that object. In this case, with an event it would try a route for EventsController#show.

In your routes.rb file, you have not defined a route for the show action in EventsController – by adding that, you will be able to get the redirect that you want.

Also, since you already have the other actions like create and index defined, you can replace them all with resources :events in your routes.rb file as that will generate all of them automatically.

Because you're trying to redirect to the 'show' action

23 format.html { redirect_to @event, notice: 'Event was successfully created.' }

But there is no route to action 'show' in your config/routes.rb

This is the issue: NoMethodError (undefined method `event_url' for # <EventsController:0x00000004aebd80>)

Are you trying to pass in an event_url? Your events table doesn't have an event_url. So the fix would be a few things:

  1. rails g migration AddEventUrlToEvents event_url:string
  2. rake db:migrate
  3. Add event_url to your permitted params in your events controller.
