Getting user phone number and sending a message in ruby on rails - ruby-on-rails

Question

I am working on a messaging app in ruby and i am currently encountering a blocker which i can not fix. I have been using tutorials for this and i think part of the reason i cannot find the solution is because of that. My app allows the users to log in and sign up,they can then add,view and edit contact. Finally the can send a message to different recipients. The problem is, i cannot get the recipients in the contacts and send them a message. I am only able to select my name as a user(which is not what its intended to do). I have attached the controllers used here:
contacts_controller
class ContactsController < ApplicationController
def index
#contacts = Contact.all
end
def new
#contact = Contact.new
end
def create
#contact = Contact.new(contact_params)
if #contact.save
flash[:success]= "new contact successfully added!"
redirect_to contacts_path
else
render 'new'
end
end
def edit
#contact = Contact.find(params[:id])
end
def update
#contact = Contact.find(params[:id])
permitted_columns = params.require(:contact).permit(:name, :company, :email, :phone)
#contact.update_attributes(permitted_columns)
redirect_to contacts_path
end
def destroy
#contact = Contact.find(params[:id])
#contact.destroy
redirect_to contacts_path
end
private
def contact_params
params.require(:contact).permit(:name, :company, :email, :phone)
end
end
messages_controller
class MessagesController < ApplicationController
def index
#messages = Recipient.where(:user_id => current_user.id).order('created_at DESC')
end
def new
#message = Message.new
#recipients = Contact.all
end
def create
#message = current_user.messages.build(message_params)
if #message.save
flash[:success]= "Message sent!"
redirect_to contacts_path
else
flash[:alert]= "sorry!message unsent"
render :new
end
end
private
def message_params
params.require(:message).permit(:body, :sender_id, user_tokens:[])
end
end
users_controller
class UsersController < ApplicationController
def index
end
def create
user = User.new(user_params)
if user.save
session[:user_id] = user.id
redirect_to '/contact'
else
flash[:register_errors] = user.errors.full_messages
redirect_to '/'
end
end
private
def user_params
params.require(:user).permit(:fname, :lname, :email, :password, :password_confirmation)
end
end
sessions_controller
class SessionsController < ApplicationController
def create
user = User.find_by(email:login_params[:email])
if user && user.authenticate(login_params[:password])
session[:user_id] = user.id
redirect_to '/contact'
else
flash[:login_errors] = ['invalid username or password']
redirect_to '/'
end
end
def destroy
session[:user_id] = nil
redirect_to '/', notice: 'Successfully logged out!'
end
private
def login_params
params.require(:login).permit(:email,:password)
end
end
The _recipient.html.erb is rendered by the new.html.erb. Here is the code:
<div class="container vertical-center">
<div id ="stream">
<%= form_for :message, url:messages_path do |f| %>
<%= f.text_area :body, id: "url", placeholder: "Message", class: "message_body" %>
<div id="stream-list" class="follow-list">
<ul>
<% #recipients.each do |contact| %>
<label for="user<%=contact.id%>" >
<li id="stream_item">
<span class="list-group-item"><%= contact.name %></span><%= check_box_tag "message[user_tokens][]",user.id, #message.users.include?(user), id: "user#{user.id}" %>
</li>
</label>
<br>
<% end %>
</ul>
</div>
<div class="stream-footer">
<%= f.button :submit, class: "btn btn-success" %>
<% end %>
</div>
</div>
</div>
Here is the error when i try to write a message

It's not very clear why you use local variable user in your view template. I think it's just an error and contact variable is supposed to be used instead:
<span class="list-group-item"><%= contact.name %></span><%= check_box_tag "message[user_tokens][]", contact.id, #message.users.include?(contact), id: "user#{contact.id}" %>
Also, a small HTML error: ul tag should contain li tags; other tags are not allowed as direct descendants. So I would also rewrite that list as:
<ul>
<% #recipients.each do |contact| %>
<li id="stream_item">
<label for="user<%=contact.id%>" >
<span class="list-group-item"><%= contact.name %></span><%= check_box_tag "message[user_tokens][]", contact.id, #message.users.include?(contact), id: "user#{contact.id}" %>
</label>
</li>
<br>
<% end %>
</ul>
