Method: Mango::Application.not_found

Defined in:
lib/mango/application.rb

.not_found ⇒ Object

Renders a 404 page with a 404 HTTP response code.

First, the application attempts to render a public 404 file stored in settings.public_dir. If a public 404 file is found, the application will:

  • Send the public 404 file with a 404 HTTP response code
  • Halt execution

For example:

`-- themes
    `-- default
        `-- public
            `-- 404.html

GET /page_not_found => 404 themes/default/public/404.html

If no match is found, the application attempts to render a 404 template stored in settings.views. If a 404 template is found, the application will not render it within a layout template, even if an appropriately named layout template exists within settings.views. If a 404 template is found, the application will:

  • Render the 404 template, without a layout template, as HTML
  • Send the rendered 404 template with a 404 HTTP response code
  • Halt execution

For example:

|-- content
|   `-- index.haml
`-- themes
    `-- default
        `-- views
            `-- 404.haml

GET /page_not_found => 404 themes/default/views/404.haml

Finally, if no matches are found, the application sends a basic "Page Not Found" page with a 404 HTTP response code.
