SimplificatorInfrastructure

This project rocks and uses MIT-LICENSE.

SimplificatorInfrastructure provides re-usable code for Rails Webapps.

Error Pages

Shows neat error pages when exceptions are raised. It is implemented as exception app which is a special rack app which gets called when an error occurs inside the rack middleware chain.

Installation

““

gem 'simplificator_infrastructure'

““

Usage

In order to enable the error page handling do something like this:

““

SimplificatorInfrastructure::ErrorPageHandler.register

# As this will hide useful information for developers
# you might want to do this depending on the environment
if Rails.env.production?
  SimplificatorInfrastructure::ErrorPageHandler.register
end

““

Note: it’s best if you do this in an after_initialize block or in an initializer file (initializers/*.rb) because in order for the error pages to work consider_all_requests_local needs to be false. Some environments set it to true which might override this again because of the order of the calls.

Customize Error pages

You can add an error page per HTTP status code. I.e. a custom 500, 404, … error page. The gem comes with

  • 404 (is shown when a routing error occurs)

  • generic (is shown in all other cases)

If a specific page is present then it is rendered, else the generic one is shown.

To add or customize an error page you can add a view at

app/views/errors/xxx.html.something

where XXX is the status code

Or add

app/views/errors/generic_error.html.erb to replace the generic error view.
