Hello all. I''m new to RoR. I am having trouble trying to get a simple
edit/update going. Everytime I hit submit, I get the following error:
+++++++++++++++++++++
Couldn''t find Content without an ID
Request
Parameters:
{"format"=>"#<content:0x4d3daac>",
"commit"=>"Update",
"_method"=>"put",
"authenticity_token"=>"axBSuIWVTMRB2CKcmMO59tqtOlMtXRSXQQ7xeHEMd78=",
"content"=>{"title"=>"About Us",
"verbiage"=>"The company was formed in 2008 by seven
healthcare
professionals involved in the areas of acute care hospital,
rehab hospital,
skilled nursing and rehab,
out-patient clinics,
and Home Health Care. Update"}}
+++++++++++++++++++++++++++++
I have a form called edit.html.erb:
<h2>Edit content</h2>
<% form_for @content do |f| %>
<p>
<%= f.label :title %><br/>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :verbiage %><br/>
<%= f.text_area :verbiage %><br/>
</p>
<%= f.submit "Update"%>
<% end %>
+++++++++++++++++++++++++++++++++++++
Here''s my controller code:
class ContentsController < ApplicationController
layout ''subpages''
def new
@content = Content.new
end
def create
@content = Content.new(params[:content])
@content.save
end
def edit
@content = Content.find(params[:id])
end
def update
@content = Content.find(params[:id])
@content.update_attributes(params[:content])
redirect_to :action => "edit", :id => @content.id
end
end
++++++++++++++++++++++++++++++++++++
i''ve been trying to figure this out for 3 days but no luck. The
solutions on the web and books seem to explain that I need to have id
passed to the controller, but I thought form_for @content should
already take care of that. I would appreciate all the help i can get.
Thanks.

If you did not use a generator to make your scaffolding, then you may not have your routes set up correctly. new might be calling edit so there is not parameter.

Thanks for your replies. I didn''t use / or generate scaffolding for this project.

Uggh! I can''t believe it''s that missing ''s'' that was causing me heartache. I also changed ''content'' to ''contents'' and it''s working fine after the update.

Thanks. Well, I work on my project a few hours a day after work so it''s not exactly 3 straight days. But you''re right, sometimes Googling just isn''t enough. I''m glad to have found this group. I''m pretty sure I''ll have a few more questions later. Any other books you can recommend for Ruby on Rails? I''m starting to love this new framework after just a few days of experimenting and would like to continue going deeper.

The best book in my opinion is Agile Web Development with Rails (then The Rails Way when you get a bit more advanced).
