    <p>I want to have a rake task that reads a HAML file and creates a static html file out of it. The reason for this is that I want to dynamically localize my error pages in a manner described here <a href="http://devcorner.mynewsdesk.com/2010/01/13/rails-i18n-and-404500-error-pages/" rel="nofollow noreferrer">http://devcorner.mynewsdesk.com/2010/01/13/rails-i18n-and-404500-error-pages/</a></p> <p>Here is the method for writing the error pages.</p> <pre><code>def write_error_page(status, locale = nil) dest_filename = [status.to_s, locale, "html"].compact.join(".") File.open(File.join(Rails.root, "public", dest_filename), "w") do |file| path = File.join(Rails.root, "app", "views", "errors", "#{status}.haml") file.print Haml::Engine.new(File.read(path)).render end end </code></pre> <p>The problem is that Haml::Engine does not have rails methods available. So when a try to read the haml file, I get an error for every rails method in the file (I want to use methods like image_tag, form_for and obviously I18n.translate).</p> <p>I noticed a similar issue that had been solved here: <a href="https://stackoverflow.com/questions/4097642/rails-haml-engine-rendering">Rails HAML engine rendering</a></p> <p>However, when I try the solution mentioned in the link above, I get the following error: "undefined local variable or method `config' for #".</p> <p>How could I get the rails methods to work in the Haml::Engine so that I could read the HAML file? I also tried switching to ERB, but noticed that it leads to the same problem, which somebody else has at least partially resolved here <a href="https://stackoverflow.com/questions/3922469/render-erb-from-database-into-view-problem-please-help">render erb from database into view problem please help!</a> But this solution didn't help me either.</p> <p>I'm also open to other solutions than using Haml::Engine. I looked into capture_haml helper but don't see how that would help me either.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
