How to set up a Phoenix route that takes multiple params in the query string

I am looking to generate a route in Phoenix that will accept 2 query params.

get "/items?id=:id&action=:action", ActionController, :index_by

But I get the following error:

(Plug.Router.InvalidSpecError) :identifier in routes must be made of letters, numbers and underscores

I noticed that when I remove the second parameter that it compiles just fine, so I am guessing this has something to do with the delimiter & to separate out the params in the query string.

Is there another way to specify multiple params like that to differentiate the route?

Route definitions are mainly for 'clean urls' since it matches on the request path (without the query string).

With that in mind, you can define your route like this

get("item/:id/:action", ActionController, :index_by)
#Or
get("/items", ActionController, :index_by)

The first route definition will capture id and action from the request path e.g GET /items/1/edit will give you %{"id"=>1, "action"=>"edit"} in your params.

The second will capture id and action from the query string. e.g GET "/items?id=1&action=delete" will give you %{"id"=>1, "action"=>"delete"} in your params

Note that, the second route definition, unlike the first, does not enforce the presence of either id or action in the query string so you are not guaranteed those paramaters will be available in your params.
