Ruby on Rails + FriendlyId gem + Acts_as_Votable gem-收到Heroku错误

Question

In my index page I have the following as part of setting up the Acts_as_votable gem.

<%= link_to like_bike_path(bike), method: :put, class: "btn btn-default" do %>

It was working fine until I added FriendlyId, probably because the like_bike_path is looking for an id not a friendlyID (ie vanity URL). Is there a way to change

like_bike_path

to something like

like_friendly.find_path

Works on Localhost:3000 but Heroku logs tell me ActionView::Template::Error (undefined method slug' for #<Bike" for my two acts_as_votable calls "like_bike_path(bike)" and "<%= bike.get_upvotes.size %>".

thanks!

Answer 1

#app/models/bike.rb
class Bike < ActiveRecord::Base
   extend FriendlyId
   friendly_id :column, use: [:finders, :slugged]
end

This will allow use of the slug without having to change the default pattern in ActiveRecord... ( @bike = Bike.find params[:id] ).

In regards your heroku error, it means you have not got the database migrated (it doesn't include slug in its columns).

You need to make sure you run heroku run rake db:migrate , as well as ensuring that you've re-saved any @bike records (so the slug column is populated).
