nomethoderror in projects#blogs undefined method `bloglikes_path' extracted source (around line #11): 11:     <%= form_for(current_user.bloglikes.build(blogupdate_id: blogupdate.id)) |f| %> 

question: note, have not built controller actual create/destroy function in bloglikes controller; looking @ attached code below, know how can resolve error like/unfollow button renders?

projects_controller.rb

def blogs     @project = project.find(params[:id])     @blogupdates = @project.blogupdates.newest.page(params[:blogupdates_page]).per_page(5) end

<%= render @blogupdates %> 

views/blogupdates/_blogupdates.html.erb

<%= blogupdate.liked_by.count %> <% if current_user.liking_blogupdate?(blogupdate) %>   <%= form_for(current_user.bloglikes.find_by_blogupdate_id(blogupdate),                html: { method: :delete }) |f| %>     <%= f.submit "unlike", class: "btn btn-medium" %>   <% end %> <% else %>   <%= form_for(current_user.bloglikes.build(blogupdate_id: blogupdate.id)) |f| %>       <div><%= f.hidden_field :blogupdate_id %></div>       <%= f.submit "like", class: "btn btn-medium btn-primary" %>    <% end %> <% end %>  <p><%= raw blogupdate.content %></p> 

update: noted below @dan, forgot update routes.rb file. added "resources :bloglikes" , worked now.

you didn't post routes.rb file i'd wager problem at. undefined method related routes (e.g. bloglikes_path) typically indicates you've not defined routes.

add resources :bloglikes project's routes.rb file , see if resolves issue.
