Constructor Details

- (Route) initialize(path_spec, resource, bindings = {})

Creates a new Route that will associate a pattern to a Resource.

Parameters:

  • path_spec (Array<String|Symbol>) —

    a list of path segments (String) and identifiers (Sybmol) to bind. Strings will be simply matched for equality. Symbols in the path spec will be extracted into Request#path_info for use inside your Resource. The special segment MATCH_ALL will match all remaining segments.

  • resource (Class) —

    the Resource to dispatch to

  • bindings (Hash) (defaults to: {}) —

    additional information to add to Request#path_info when this route matches

Raises:

  • (ArgumentError)
