Question

I’m using acts-as-messageable, a rails gem, in an app i have.

However in my messages_controller i have

def new 
  @message = ActsAsMessageable::Message.new
end 

and in my view i have

<%= form_for(@message) do |f| %>

which throws the following error

undefined method `acts_as_messageable_messages_path’

I’m not really sure why this is happening with the gem.

Answer 1

Try explicitly stating what path you want the form to point towards (which should be the messages#create action):

<%= form_for(@message) :url => messages_path, :method => :post do |f| %> 
  <div class="field">
    <%= f.label :to %><br />
    <%= f.email_field :to %>
  </div>
  <div class="field">
    <%= f.label :topic %><br />
    <%= f.text_field :topic %>
  </div>
  <div class="field">
    <%= f.label :body %><br />
    <%= f.text_area :body %>
  </div>

  <button type="submit" class="btn primary">Send</button>
  <button type="reset" class="btn">Cancel</button>
<% end %>

This assumes that you have this in your routes.rb file:

resources :messages

Also, make sure you are passing in the required fields to ActsAsMessageable: https://github.com/LTe/acts-as-messageable/wiki/Example-controller
