Rails routing error: No route matches [GET] "/conversations/'id'/reply" - ruby-on-rails

Question

I'm having trouble replying to conversations with the Mailboxer gem in Rails 4. There isn't a whole lot of documentation on this gem, or maybe I'm just not experienced enough, but I've been stuck on this for a while now.
view/conversations/index:
(shows list of all current user's conversations)
<% #conversations.each do |conversation| %>
<%= link_to conversation.subject, reply_conversation_path(conversation.id) %>
<%= conversation.updated_at.strftime("%a, %m/%e/%Y %I:%M %p") %>
<%= link_to "Move to Trash", {:controller => "conversations", :action =>
"trash", :id => conversation.id}, :title=> "Move to Trash", :method=>'post' %>
<% end %>
When I click the first link_to in the above view, I receive the routing error: No route matches [GET] "/conversations/68/reply".
I was hoping to have it render the following view, and have the correct conversation passed to it:
view/messages/_form/
(used to reply to existing conversations)
Reply:
<%= form_for :message, url: [:reply, conversation] do |f| %>
<%= f.text_area :body %>
<%= f.submit "Send Message", class: 'btn btn-primary' %>
<%= submit_tag 'Clear Reply Box', type: :reset, class: 'btn btn-danger' %>
<% end %>
Routes:
resources :users
root to: 'profiles#index'
resources :messages do
member do
post :new
end
end
resources :conversations do
member do
post :reply
post :trash
post :untrash
end

get :trashbin

end

#user = #request.user
end
# POST /message/create

Answer 1

The route is a post route:
resources :conversations do
member do
post :reply
Your form needs to use an HTTP POST request, and because you haven't specified a method, it's defaulting to a GET request.
Replace this...
<%= form_for :message, url: [:reply, conversation] do |f| %>
with this:
<%= form_for :message, url: [:reply, conversation], method: :post do |f| %>

Answer 2

Your rake routes shows reply_conversation POST /conversations/:id/reply(.:format) conversations#reply but your link_to will send a get request. You need to change your route to make it a get request.
