form_for not rendering

[Paulo Carvalho]

Hello

I am developing an application on rails using a couchDB database. I already can connect to the database and view some information.
Now I am trying to create a new object of my model.

My model is named author. My controller is named authors.

The code of my model is the following one:

class Author < CouchRest::Model::Base
  
  timestamps!
  
  property :_id, String
  property :id, Integer
  property :title, String
  property :first_name, String
  property :last_name, String
  
  view_by :id,
          :map => "function(doc) {
            if(doc._id.indexOf('Authors_') == 0) {
              emit(null, doc);
            }
          }"
end

The code of my controller is the following one:

class AuthorsController < ApplicationController
  def list
    @authors = Author.by_id()
  end

  def new
    @author =Author.new    
    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @author }
    end
  end

end

The code of my new.html.erb file is the following one:

<h1>New author form</h1>

<% form_for @author do |f| %>
	<div class="field">
		<p><%= f.label :title %>
		<%= f.text_field :title %></p>
	</div>
	
	<p><%= f.label :first_name %>
  	<%= f.text_field :first_name %></p>
  
  	<p><%= f.label :last_name %>
  	<%= f.text_field :last_name %></p>
  	
  	<div class="action">
  		<p><%= f.submit :create %></p>
  	</div>
  	
<% end %>

<%= link_to 'Back', authors_path %>

The list method is working fine, it shows what I am expecting to.
However, the "new" html page does not shows anything except the title and the "back" link. No error is generated. Everything is ok except that the form is not generated/displayed/rendered.
Does anyone have an idea about the problem/solution of it?
Thank you
Best regards

Hi there,

You didn't say which version of Rails you're using, but I'm going to just assume Rails 3 for a second.

Have you tried changing this:

<% form_for @author do |f| %> 

into

<%= form_for @author do |f| %> 

?

Yes, this was the problem...

Thank you very much.

Best regards.
