Allowing current_user to email #user from users#show/ - ruby-on-rails

Question

I've set up Rails 4 ActionMailer to send me (as site admin) an email whenever a new user signs up (registrations#create - I'm using Devise).
Now I would like for current_user to be able to email the user whose profile they are currently viewing. So in users#show I'd like to have a form that simply generates an email :to #user.email, :from current_user.email (optionally override-able via text input), and possibly a body to the message.
A record of the message is not important. For this implementation I'm letting the users' inboxes handle all of the history. In fact I'd rather not store that data if it's possible to just pass it through the model/controller. If the addition of body text necessitates the use of a MessagesController then I would rather leave that out.
Many thanks.

Answer 1

<%= form_for(Message.new) do |f| %>
<div class="form-inputs">
<%= f.text)area :message %>
</div>
<%= f.hidden_field :sender_email, value: current_user.email %>
<%= f.hidden_field :receiver_email, value: #user.email %>
<div class="form-actions">
<button type="submit">Email</button>
</div>
<% end %>
Your message model will look like this
class Message
include ActiveModel::Model
def initialize(attributes = {})
attributes.each do |name, value|
send("#{name}=", value)
end
end
def persisted?
false
end
end
Message controller
class MessagesController < ApplicationController
def create
#message = Message.new(params.require(:message).permit(:sender_email, :receiver_email, :message))
if #message.valid?
MessageMailer.send_message(#message).deliver
redirect_to profile_url, notice: "Message sent"
else
render :new
end
end
end
class MessageMailer < ActionMailer::Base
def send_message(message)
#body = message.message
#from = message.sender_email
#to = message.receiver_email
mail to: #to, :subject => "new mail", :from => #from
end
end
The above code is not tested hope it works for your need
