Ruby on Rails pass value to another view - ruby-on-rails

Question

I'm using Mailboxer as my messaging gem in my rails app.
So the site's about classifieds. Every classified has a contact seller link , which i have implemented to route to the new_message form and write the message to the recipient fine!
Now i want to add some info about the classified that the contact form is made for!
class MessagesController < ApplicationController
before_action :authenticate_user!
def new
#user = User.find_by(id: params[:recipient_id])
end
def name
first_name
end
def mailboxer_email(object)
email
end
def create
recipients = User.find_by(id: params[:recipient_id])
conversation = current_user.send_message(recipients, params[:message][:body], params[:message][:subject]).conversation
flash[:success] = "Message has been sent!"
redirect_to conversation_path(conversation)
end
end
This is the view where i call new_message_path and then retrieve the user_id to define the recipient.
<div class="center-div">
<div class="col-lg-12" id="image">
<% #classified.photos.each do |p| %>
<h3 class="dark-grey"><%= #classified.title %></h3>
<h5 class="dark-grey">Loved by: <%= #classified.favorited_by.count %> </h5>
<%= image_tag p.image %>
<%end%>
</div>
<%= link_to "", new_message_path(:recipient_id => #classified.user_id), :class => "glyphicon glyphicon-envelope" , :style => "color:#EFCE7B" %>
<%if current_user.favorite_classifieds.collect(&:classified_id).include?(#classified.id) %>
<%= link_to "", favorite_classified_path(#classified, type: "unfavorite") , :class => "glyphicon glyphicon-heart" , :style => "color:#FF0000", method: :put %>
<%else%>
<%= link_to "", favorite_classified_path(#classified, type: "favorite") , :class => "glyphicon glyphicon-heart" , :style => "color:#000000", method: :put %>
<%end%>
<%= link_to "", editlisting_path(#classified) , :class => "glyphicon glyphicon-flag" , :style => "color:#EB573B" %>
<ul>
<h3 class="dark-grey">Model</h3>
<li><%= #classified.model %></li>
<h3 class="dark-grey">Description</h3>
<li><%= #classified.description %></li>
<li><%= link_to "Back", '/' , :class => "link" %></li>
<li><%= link_to #classified.user.first_name, profile_path(#classified.user_id) %></li>
</ul>
</div>
and this is my message_new view where i want to have the data of the classified
<div class="center-div">
<div class="messages-box">
<% page_header "Αποστολή μηνύματος" %>
<%= form_tag messages_path, method: :post do %>
<div class="form-group">
<%= label_tag 'message[subject]', 'Subject' %>
<%= text_field_tag 'message[subject]', nil, class: 'form-control', required: true %>
</div>
<div class="form-group">
<%= label_tag 'message[body]', 'Message' %>
<%= text_area_tag 'message[body]', nil, cols: 3, class: 'form-control', required: true %>
</div>
<div class="form-group">
<%= hidden_field_tag(:recipient_id, "#{#user.id}") %>
</div>
<%= submit_tag 'Send', class: 'btn btn-primary' %>
<% end %>
</div>
</div>
also for any solution a good explanation would help me a lot.
Thank you.

I ended up using nested routes.
resources :classifieds do
put :favorite, on: :member
resources :messages do
end
end
this is my view
<div class="center-div">
<div class="col-lg-12" id="image">
<% #classified.photos.each do |p| %>
<h3 class="dark-grey"><%= #classified.title %></h3>
<h5 class="dark-grey">Loved by: <%= #classified.favorited_by.count %> </h5>
<%= image_tag p.image %>
<%end%>
</div>
<%= link_to "", new_classified_message_path(:recipient_id => #classified.user_id , :classified_id => #classified.id), :class => "glyphicon glyphicon-envelope" , :style => "color:#EFCE7B" %>
<%if current_user.favorite_classifieds.collect(&:classified_id).include?(#classified.id) %>
<%= link_to "", favorite_classified_path(#classified, type: "unfavorite") , :class => "glyphicon glyphicon-heart" , :style => "color:#FF0000", method: :put %>
<%else%>
<%= link_to "", favorite_classified_path(#classified, type: "favorite") , :class => "glyphicon glyphicon-heart" , :style => "color:#000000", method: :put %>
<%end%>
<%= link_to "", editlisting_path(#classified) , :class => "glyphicon glyphicon-flag" , :style => "color:#EB573B" %>
<ul>
<h3 class="dark-grey">Model</h3>
<li><%= #classified.model %></li>
<h3 class="dark-grey">Description</h3>
<li><%= #classified.description %></li>
<li><%= link_to "Back", '/' , :class => "link" %></li>
<li><%= link_to #classified.user.first_name, profile_path(#classified.user_id) %></li>
</ul>
</div>
Got the value from the controller
class MessagesController < ApplicationController
before_action :authenticate_user!
def new
#user = User.find_by(id: params[:recipient_id])
#classified = Classified.find_by(id: params[:classified_id])
end
def name
first_name
end
def mailboxer_email(object)
email
end
def create
classifieds = Classified.find_by(id: params[:classified_id])
recipients = User.find_by(id: params[:recipient_id])
conversation = current_user.send_message(recipients, params[:message][:body], params[:message][:subject]).conversation
flash[:success] = "Message has been sent!"
redirect_to conversation_path(conversation)
end
end
and last rendered it in my messages_new view
<div class="center-div">
<div class="messages-box">
<% page_header "Αποστολή μηνύματος" %>
<%= form_tag messages_path, method: :post do %>
<div class="form-group">
<%= label_tag 'message[subject]', 'Αποστολή μηνύματος για την αγγελία : ' %>
<%= label_tag(:classified_id, "#{#classified.title}") %> <!-- integrate this -->
<%= text_field_tag 'message[subject]', nil, class: 'form-control', required: true %> <!-- integrate here -->
</div>
<div class="form-group">
<%= label_tag 'message[body]', 'Μύνημα στον χρήστη : ' %>
<%= label_tag(:recipient_id, "#{#user.first_name}") %>
<%= text_area_tag 'message[body]', nil,rows: 15, cols: 3, class: 'form-control', required: true %> <!-- integrate here -->
</div>
<div class="form-group">
<%= hidden_field_tag(:recipient_id, "#{#user.id}") %>
</div>
<%= submit_tag 'Send', class: 'btn btn-primary' %>
<% end %>
</div>
</div>
