create a button that pulls a table id and user id - ruby-on-rails

Question

I have a page that has a list of referrals on it. I have a button on each of the referrals that is set to reply to the referral. I don't need any pop up or form to show except for a flash message to show the user has successfully replied to the referral and toggling a class on the button when a user replies. Upon replying to the referral, email(is index for the table) is passed, referralid is also passed to the reply table. I have tried many methods, but I'm getting nowhere with the controllers. I created proper associations on the models, but still getting nowhere in the controller logic to create a reply record for every reply. Here are my models:
Referral Model
class Referral < ActiveRecord::Base
attr_accessible :referraltype
belongs_to :user
validates :user_id, presence: true
has_many :replies
def nil_zero?
self.nil? || self == 0
end
end
User Model
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :omniauthable
attr_accessible :name, :email, :password, :password_confirmation, :remember_me, :provider, :uid, :image
has_attached_file :image, styles: { medium: "320x320>", thumb: "50x50" }
has_many :referrals
has_many :replies
end
Replies Controller
class RepliesController < ApplicationController
end
Reply Model
class Reply < ActiveRecord::Base
belongs_to :user
belongs_to :referral
end
Referrals Controller
class ReferralsController < ApplicationController
before_filter :authenticate_user!
def reply_to_referral
#referral = Referral.find(params[:referral_id])
#replier_id = params[:replier_id]
#reply = #referral.replies.create(replier_id: #replier_id)
flash[:success] = "Referral reply sent."
redirect_to root_path
end
# GET /referrals
# GET /referrals.json
def index
#referrals = Referral.order("created_at desc")
#referrals
respond_to do |format|
format.html # index.html.erb
format.json { render json: #referrals }
end
end
# GET /referrals/1
# GET /referrals/1.json
def show
#referral = Referral.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #referral }
end
end
# GET /referrals/new
# GET /referrals/new.json
def new
#referral = current_user.referrals.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: #referral }
end
end
# GET /referrals/1/edit
def edit
#referral = current_user.referrals.find(params[:id])
end
# POST /referrals
# POST /referrals.json
def create
#referral = current_user.referrals.new(params[:referral])
respond_to do |format|
if #referral.save
format.html { redirect_to #referral, notice: 'Referral was successfully created.' }
format.json { render json: #referral, status: :created, location: #referral }
else
format.html { render action: "new" }
format.json { render json: #referral.errors, status: :unprocessable_entity }
end
end
end
# PUT /referrals/1
# PUT /referrals/1.json
def update
#referral = current_user.referrals.find(params[:id])
respond_to do |format|
if #referral.update_attributes(params[:referral])
format.html { redirect_to #referral, notice: 'Referral was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #referral.errors, status: :unprocessable_entity }
end
end
end
# DELETE /referrals/1
# DELETE /referrals/1.json
def destroy
#referral = current_user.referrals.find(params[:id])
#referral.destroy
respond_to do |format|
format.html { redirect_to referrals_url }
format.json { head :no_content }
end
end
end
Routes.rb
GemPort::Application.routes.draw do
resources :referrals do
resources :replies
member do
put "reply_to_referral"
end
end
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
root :to => 'pages#home'
get 'about' => 'pages#about'
end
Migration for the Replies table
class CreateReplies < ActiveRecord::Migration
def change
create_table :replies do |t|
t.references :user
t.references :referral
t.timestamps
end
add_index :replies, :user_id
add_index :replies, :referral_id
end
end
code on the _referral.html.haml partial that is giving the error:
= link_to '<i class="icon-ok icon-large pull-right icon-grey" rel="tooltip" title="Reply"> Reply</i>'.html_safe, reply_to_referral_path(referral_id: referral.id, replier_id: current_user.id)
I know this must be simple to do in the controller, I tried using a helper but got nowhere

Answer 1

Add your routes and controller and we can give you a better answer, but I'm guessing that this isn't working since you're passing an email to the route.
Emails have full stops (.) which can break your route unless you add constraints to the route.
Try changing your route to something like:
resources :referrals do
member do
put "reply_to_referral" # will give you referrals/:id/reply_to_referral
end
end
Now change your link to reply_to_referral_path(id: referral.id, email: current_user.email), this should come out as /referrals/32/reply_to_referral?email=user#email.com
Then in referrals controller:
def reply_to_referral
#referral = Referral.find(params[:id])
#email = params[:email]
# now make sure your referral_replies table has a column called 'email' and
# also one called 'referral_id', then you can do:
#referral_reply = #referral.referral_replies.create(email: #email)
flash[:success] = "Referral reply sent."
redirect_to # wherever required
end
You could do something similar by adding a constraint to the route, or by passing in the user's id instead of email and then querying the database.
To style the button you can then check if the referral has any replies:
<% if referral.referral_replies.any? %>
# add a CSS class
<% end %>
