Rails mailboxer gem cannot send message

Question

I am using Mailboxer gem for the messaging function, but as I am very new I am not very sure how to use it. Basically I created the following message controller:

class MessagesController < ApplicationController
  before_action :set_message, only: [:new, :create]

  def new
    @message = Message.new
  end

  def create
    current_user.send_message(@recipient, message_params(:body, :subject))
    redirect_to conversations_path
  end

  private

  def set_message
    @recipient = User.find(params[:recipient_id])
  end

  def message_params
    params.require(:message).permit(:body, :subject)
  end
end

Then my view:

<h1>New Message</h1>

<%= simple_form_for(@message, html: {class: "form-horizontal"}) do |f| %>
  <%= f.error_notification %>

  <%= f.input :subject %>
  <%= f.input :body, as: :text, input_html: { rows: "3"} %>

  <div class="form-actions">
    <%= f.button :submit, class: "btn btn-primary" %>
  </div>
<% end %>

But I can't send message... (BTW I can send message is the console, and also replace part of the message controller with "current_user.send_message(@recipient, "test", "test")", but definitely not what I want)

Use form_tag instead of form_for

Instead of using form_for, try using form_tag, as this has worked for me:

<%= form_tag("/messages/send_message", method: "post", url: send_message_path) do  %>
<%= hidden_field_tag :user_id, "#{@user.id}" %>
<%= text_field_tag :subject, nil, :class => 'form-control', :placeholder => "Subject" %>
<%= text_area_tag :message, nil, :class => 'form-control', :placeholder => "Message" %>
<%= submit_tag "Submit", :class => "btn btn-primary" %>
<% end %>

This would have an action you messages controller like this:

def send_message
@user = User.find(params[:user_id])
@message = params[:message]
@subject = params[:subject]
current_user.send_message(@user, "#{@message}", "#{@subject}")
redirect_to root_path
end

And something like this in you routes file:

post '/messages/send_message', :to => "messages#send_message", :as => "send_message"

Really hope this helps!
