How to access recipient on sent messages page with mailboxer

Question

I am using the mailboxer gem to send messages within my ruby on rails app. The gem is working. I can't for the life of me figure out how to access the recipient on the sent messages page. On the sent messages page, I am trying to loop through sent messages, and access the recipient of the sent messages and display that person to the user.

On the regular inbox page, I used the following:

<% all_mail = current_user.mailbox.inbox %>
<% all_mail.each do |letter| %>
    <tr>
        <td><%= letter.messages.last.sender.email %></td>
        <td><%= letter.messages.last.subject %></td>
   </tr>
<% end %>

I am trying to make a similar look for the sent messages page, but I can't figure out how to do it(specifically access the email of the recipient).

I can't use:

#user wants to retrieve all his conversations
user.mailbox.conversations

#user wants to retrieve his inbox
user.mailbox.inbox

#user wants to retrieve his sent conversations
user.mailbox.sentbox

because there is no way to organize how the messages are displayed using those methods (at least as far as I know). How can I loop through the messages and find the message recipient for each message?

Answer 1

You have the participants in conversations (you call it letters).

Just filter the current user and you'll be good.

conversation = user.mailbox.sentbox.first
filtered_participants = conversation.participants.reject do |u| 
  u.id == current_user.id
end
