also I try to figure it out what the meaning link_path
in this code
def create(conn, %{"link" => link_params}) do
case create_link(link_params) do
{:ok, link} ->
conn
|> put_flash(:info, "Link created successfully.")
|> redirect(to: Routes.link_path(conn, :show, link))
{:error, changeset} ->
render(conn, "new.html", changeset: changeset)
end
end
