How do I edit my Profile that is associated with User?

Question

I created the model User and the model Profile. On my homepage I have a link in the dropmenu navigation bar that links to Edit Profile. The problem I face is "No route matches {:action=>"edit", :controller=>"profiles", :id=>nil} missing required keys: [:id]".

The route for edit page is "edit_profile_path" with verb GET and URI pattern "/profiles/:id/edit(.:format)". I am having a hard time getting the "id" inserted. Below is the code that I have on my app.

In model Profile file I have:

class Profile < ActiveRecord::Base
    belongs_to :user, dependent: :destroy
end

In model User file I have:

class User < ActiveRecord::Base
  has_one :profile
end

The profile has many attributes, but one of them is "user_id" which is an integer that is equal to the User's id. So User #5 with id#5 is the owner of Profile#5. Here is the code that I have in the View file:

<li><%= link_to "Edit Profile", edit_profile_path(@profile) %></li>

With regards to the code directly above, I have tried inserting different codes inside the parenthesis, from @profile.id, @profile, @user.id, and @user. But it has not worked.

I created a profiles controller and I think (but I am not certain) that my problem is coming from the profiles_controller file. Here is the code that I have:

class ProfilesController < ApplicationController
  before_action :authenticate_user!
  before_action :set_profile, only: [:edit, :update]

  def edit
  end

  def new
    @profile = Profile.new
  end

  def create
    @profile = Profile.new(profile_params)
    @profile.user_id = current_user.id
    if @profile.save
      redirect_to welcome_path
    else
      render 'new'
    end
  end

  def update
    @profile.update(profile_params)
    redirect_to welcome_path
  end

    private
      def set_profile
        @profile = Profile.find(params[:id])
      end
  end

You are getting this error because in your view, your @profile in nil. So, you have to get the current_profile in your view so that you can go to the edit page of that profile.

If you already have access to your current_user helper method, then, in your view, you can simply do:

<li><%= link_to "Edit Profile", edit_profile_path(current_user.profile) %></li>
