ruby-on-rails-3.1

New to rails and I'm following the Depot project found in the Agile web development with rails 3.1. Everything was fine until I got lost when the book used the "build" method. @cart = current_cart product = Product.find(params[:product_id]) @line_item = @cart.line_items.build(product: product) My google searches led me to understand that the .build method is just a cleaner way to create a row in the table (with association between tables). But on the code above, I was expecting the code would look like something like this: @line_item = @cart.line_items.build(product_id => params[:product_id])

Just installed rails 3.1 rc1 and am trying to grok the best way to manage javascript with the new asset pipeline By default all coffeescript is compiled into a single application.js file, this is a good thing. Each seperate coffee script file is appended to the js file and wrapped in an anonymous function which is executed via the call method A common scenario would be to use some jquery to turn various forms into ajax forms, update UI, etc... Many of these scripts will be specific to a controller or action, I am trying to grok the 'conventional' way to handle this, since everything is wrapped

When I add the 'Required' attribute to html input fields, Rails pre-pends an asterisk (*) before the label. Does anyone know how to prevent this? For some reason Rails transforms this: <%= f.input :Company, :input_html => {:value => "", :id => "company_name"}, :label => "company name" %> into this: <div class="input string required"> <label for="company_name" class="string required"> <abbr title="required">*</abbr> company name</label> <input type="text" value="" size="50" required="required" name="lead[Company]" id="company_name" class="string required"> </div> I don't like that it wraps

I see that in development environment in rails 3.1 the css are loaded in alphabetic order and not in the order I want. I want a particular css file to be at the end so it over-writes any styles given to the class before. How can we achieve that? It is better to specify the order of each and every files manually: /* * This is a manifest file that'll automatically include all the stylesheets available in this directory * and any sub-directories. You're free to add application-wide styles to this file and they'll appear at * the top of the compiled file, but it's generally better to create a new

Using Rails 3.2.1 I created a simple controller called Home using the command: rails g controller Home index And it created a new controller and view for me: Notice how there are two stylesheets, one "Application" and one "Home". I can't find any documentation to support this assumption but I'm guessing you put styles that will only be applied to the "Home" views, in the Home.css.scss file, correct? So as a test, I added in some global styles to Application.css.scss.erb and ran the application. The styles applied as expected. Next, I added in some rules to the Home.css.scss file and I visited

How can I create an after confirmation redirect in devise? Before I added the confirmation module the custom after_sign_up_path worked fine for the first time login/signup but now when I click the confirmation link in the email it redirects to the path i set for the after login path (user profile). My goal here is to create a form wizard and "getting started" page to collect additional information. The obvious caveat being that this redirect will only happen 1 time, upon confirmation. I have tried some other solutions that have been posted on stack but none of them seem to work any longer..

I just installed Passenger 3.0.11 and nginx and got this error: Starting nginx: /opt/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory The message means what it says. The nginx executable was compiled to expect the PCRE (Perl-compatible Regular Expression) shared library to be available somewhere on LD_LIBRARY_PATH or specified in /etc/ld.so.conf or whatever equivalent library-locating mechanisms apply to your operating system, and it cannot find the library. You will need to install PCRE - or configure your
