Subject: Re: [Rubyonrails-ug] controller problem !
Dein Formular ist verkehrt. Mach aus dem :books ein :book
und benenne die restlichen books in f um.
in etwa so:
<% form_for :book , :url => { :action => 'index' } do |f| %>
<p>
<label> :source </label><br>
<%= f.text_field :source %>
</p>
<p>
<label>:depth </label><br>
<%= f.text_field :depth %>
</p>
<p>
<label>:destination </label><br>
<%= f.text_field :destination %>
</p>
<p>
<label>:dest_space </label><br>
<%= f.text_field :dest_space %>
</p>
<p>
<label>:parentId </label><br><br>
<%= f.text_field :parentId %>
</p>
<p>
<%= f.submit_tag "Create" %>
Gruss,
