how can i handle the has_friendship gem in my application?

I'm new into rails and I want my users to be able to befriend each other so i found the gem has_friendship github: has_friendship. I did the instructions and kinda tested everything in the rails c console. And everything worked fine. But now im kinda confused how to handle it in my application, and how to integrate it to my application. Do i need an extra friendship controller/model/view or where can i define the methods like @user1.friend_request(@user2) and how do i get the id of user2?

Thanks alot!

Update

for example: i thought about displaying every user in my user index.html.erb with a link. But how am i able to trigger the friend_request method by pressing this link?

<% @users.each do |user| %> <h1><%= user.username %> <%= link_to "Add Friend", user_add_friend_path(:user_id) %></h1> <%end%>

i also edited in my routes.rb 

  resources :users do
    get 'add_friend'
  end

and made a method in my users_controller.rb 

  def add_friend
    if current_user.friend_request(@friend)
      redirect_to users_path, notice: "Friend request successfully sent."
    else
      redirect_to users_path, notice: "There was an error sending the friend request"
    end
  end

now i am getting a noMethod error because i did not define @friend yet. But how do i get the User i want to be befriended with?

Cool - sounds like a fun gem! It looks like after you run the has_friendship generator, you need to run a migration, which will alter your schema tables and you'll need to add has_friendship to your User model. If you can share some more code, then it will be easier for people to offer assistance.

You do not need any other model, only the user's, the gem generates a model of friendship

Simply drop in has_friendship to a model user:

class User <ActiveRecord :: Base
   has_friendship
end

Methods:

# @mac sends a friend request to @dee
@ mac.friend_request (@dee)

# @dee can accept the friend request
@ dee.accept_request (@mac)

# @dee can also decline the friend request
@ dee.decline_request (@mac)

# @dee removes @mac from its friends
@ dee.remove_friend (@mac)

They are generated by the gem
