#### Functionality
[url_for](rdoc-ref:ActionDispatch::Routing::UrlFor).
For all of these options, see the documentation for
# => "http://example.com/my_app/blogs/1/posts/1#my_anchor"
polymorphic_url([blog, post], anchor: 'my_anchor', script_name: "/my_app")
# => "http://example.com/blogs/1/posts/1#my_anchor"
polymorphic_url([blog, post], anchor: 'my_anchor')
`:anchor` or `:trailing_slash`. Example usage is given below:
Also includes all the options from `url_for`. These include such things as
* `:routing_type` - Allowed values are `:path` or `:url`. Default is `:url`.
`:edit`. Default is no prefix.
* `:action` - Specifies the action prefix for the named route: `:new` or
#### Options
polymorphic_url(Comment) # => "http://example.com/comments"
polymorphic_url([user, :blog, post]) # => "http://example.com/users/1/blog/posts/1"
polymorphic_url([:admin, blog, post]) # => "http://example.com/admin/blogs/1/posts/1"
polymorphic_url([blog, post]) # => "http://example.com/blogs/1/posts/1"
polymorphic_url(post) # => "http://example.com/posts/1"
# calls post_url(post)
the resulting URL string. For example:
Constructs a call to a named RESTful route for the given record and returns
