no function clause matching in Plug controller

My function does not match in the controller My router:

scope "/api", AtmAppWeb do pipe_through :api
    get "/index", UserAtmController, :index
    get "/show", UserAtmController, :show
    get "/get_founds", UserAtmController, :get_founds
    post "/create", UserAtmController, :create
    put "/update", UserAtmController, :update
    delete "/delete", UserAtmController, :delete
end

My controller function:

def get_founds(conn, %{"id" => id}) do
    user_atm = User.get_user_atm!(id)
    json put_status(conn, :ok), %{"message" => user_atm }
end

and this is my petition:

GET /api/get_founds HTTP/1.1

Content-Type: application/json

Host: localhost:4000

Content-Length: 13

{

"id": "2"

}

I don't know where is the error:

Phoenix.ActionClauseError at GET /api/get_founds no function clause matching in AtmAppWeb.UserAtmController.get_founds/2

i expectted that my function response a message with the atm_user

Solution

  • According to docs, Phoenix.Router.get/4 does not expect a payload as JSON, but rather it expects id to be a part of path.

    That said, GET /api/get_founds/2 would work as expected assuming the route would be get "/get_founds/:id", UserAtmController, :get_founds.
