Create Human Readable URIs for Ruby on Rails Models

Update Model

Overwrite the inherited to_param method with the code snippet to return custom parameters for the model.

Parameterizing the 'title' attribute will remove any non-valid URI characters while keeping it human readable. Alternatively use URI.escape(<attribute>) to keep all characters but have them escaped for URIs.

Adding the unique model id in front of the title will ensure that URIs do not clash.


  • Assumes the model has a human-readable attribute named 'title', can be replaced with any other string attribute.
  • Tested in Ruby on Rails v5.2 and v6
