Building Rails User_Friendships based on User IDs instead of Profile Names

Hi again, I figured it out. The user_id was not being passed through in the form correctly. So in the new user_friendship form, I had to make the following change: <%= form.hidden_field :friend_id, value: @friend.profile_name %> to <%= form.hidden_field :friend_id, value: @friend.id %> Note that I had tried: <%= form.hidden_field :friend_id, value: @friend.user_id %> but it had not worked...still not sure why, but at least .id works. Thanks again for your interest in helping! Best, Lisa

Hi Twiz T,

Thanks for your response. Error is below along with my UserFriendship Controller text.

Thanks, Lisa

UserFriendship Controller text:

class UserFriendshipsController < ApplicationController before_filter :authenticate_user!, only: [:new]

def new
    if params[:friend_id]
        @friend = User.find(params[:friend_id])
        raise ActiveRecord::RecordNotFound if @friend.nil?
        @user_friendship = current_user.user_friendships.new(friend: @friend)
    else
        flash[:error] = "Friend Required"
    end
rescue ActiveRecord::RecordNotFound
    render file: 'public/404', status: :not_found
end

def create
    if params[:user_friendship] && params[:user_friendship].has_key?(:friend_id)
        @friend = User.find(params[:user_friendship][:friend_id]).first
        @user_friendship = current_user.user_friendships.new(friend: @friend)
        @user_friendship.save
        flash[:success] = "You are now friends with #{@friend.name}"
        redirect_to show_path(@friend)
    else
        flash[:error] = "Friend Required"
        redirect_to root_path
    end
end

end

Hi again,

The error from the terminal window is below. I think it is clear that the User_ID is not flowing through correctly but I can't figure out how to fix this. Any ideas would be greatly appreciated.

Thanks, Lisa

No problem, wish I could have been of more help. Sometimes it just helps to talk it out (even with yourself) :)

Agreed! :) Thxs again!
