Public Instance Methods
to_param()

Returns a String
, which Action Pack uses for constructing a URL to this object. The default implementation returns this record's id as a String
, or nil
if this record's unsaved.
For example, suppose that you have a User model, and that you have a resources :users
route. Normally, user_path
will construct a path with the user object's 'id' in it:
user = User.find_by(name: 'Phusion') user_path(user) # => "/users/1"
You can override to_param
in your model to make user_path
construct a path using the user's name instead of the user's id:
class User < ActiveEntity::Base def to_param # overridden name end end user = User.find_by(name: 'Phusion') user_path(user) # => "/users/Phusion"
# File lib/active_entity/integration.rb, line 31 def to_param # We can't use alias_method here, because method 'id' optimizes itself on the fly. id&.to_s # Be sure to stringify the id for routes end
