Rails - Liking Comments Made on Posts - NoMethodError - ruby-on-rails

Question

For my application, I have Users, who can Create Project Postings. On each Project Posting, they can make comments that I have made a Blogupdate model. I want users to be able to like Blogupdates made on each Project page.
So, I created a Bloglike model. But when I try to render a LIKE/UNLIKE button, I get the following error:
NoMethodError in Projects#blogs
undefined method `bloglikes_path'
Extracted source (around line #11):
11: <%= form_for(current_user.bloglikes.build(blogupdate_id: blogupdate.id)) do |f| %>
Question: As a note, I have not built up the controller for the actual create/destroy function in my bloglikes controller; but looking at my attached code below, does somebody know how I can resolve this error so the like/unfollow button renders?
schema.rb
create_table "bloglikes", :force => true do |t|
t.integer "user_id"
t.integer "blogupdate_id"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
add_index "bloglikes", ["blogupdate_id"], :name => "index_bloglikes_on_blogupdate_id"
add_index "bloglikes", ["user_id", "blogupdate_id"], :name => "index_bloglikes_on_user_id_and_blogupdate_id", :unique => true
add_index "bloglikes", ["user_id"], :name => "index_bloglikes_on_user_id"
user.rb
has_many :bloglikes, foreign_key: "user_id"
has_many :liked_blogupdates, through: :bloglikes, source: :blogupdate
blogupdate.rb
has_many :bloglikes, foreign_key: "blogupdate_id"
has_many :liked_by, through: :bloglikes, source: :user
def liking_blogupdate?(blogupdate)
bloglikes.find_by_blogupdate_id(blogupdate.id)
end
def like_blogupdate!(blogupdate)
bloglikes.create!(blogupdate_id: blogupdate.id)
end
def blogupdate_unlike!(blogupdate)
bloglikes.find_by_blogupdate_id(blogupdate.id).destroy
end
bloglike.rb
class Bloglike < ActiveRecord::Base
attr_accessible :blogupdate_id
belongs_to :user, foreign_key: "user_id"
belongs_to :blogupdate, foreign_key: "blogupdate_id"
end
projects_controller.rb
def blogs
#project = Project.find(params[:id])
#blogupdates = #project.blogupdates.newest.page(params[:blogupdates_page]).per_page(5)
end
views/projects/blogs.html.erb
<%= render 'blogs' %>
views/projects/_blogs.html.erb
<%= 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 }) do |f| %>
<%= f.submit "UNLIKE", class: "btn btn-medium" %>
<% end %>
<% else %>
<%= form_for(current_user.bloglikes.build(blogupdate_id: blogupdate.id)) do |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: As noted below by #Dan, I forgot to update the routes.rb file. I added "resources :bloglikes" and it worked now.

You didn't post your routes.rb file but I'd wager that is where the problem is at. An undefined method related to routes (e.g. bloglikes_path) typically indicates you've not defined the routes.
Add resources :bloglikes to your project's routes.rb file and see if that resolves the issue.
