Rails: routes

A brief breakdown of this route:

match “/pick_gender(/:gender)”, to: “my_controller#pick_gender”, via: “GET”, as: :pick_gender

1. `match` will match a GET (i.e. it will be the same as using `get`) if we use `via: “GET”

You can simplify it to:

get “/pick_gender(/:gender)”, to: “my_controller#pick_gender”, as: :pick_gender

or if you want to use the `=>` syntax to:

get “/pick_gender(/:gender)” => “my_controller#pick_gender”, as: :pick_gender

2. `to:` matches this resource (the GET on the URL) to the `pick_gender` method of the `my_controller` controller

3. finally, using `as:` will create a named route, i.e. you get a `pick_gender_path` and `pick_gender_url` for free as named helpers
