100% right! Let me post the latest code I had that worked great for me:
def uri_path(uri, params) do
params = Stringify.call(params) # utility function to stringify this map because Query params will be string only
query =
Plug.Conn.Query.decode(uri.query || "")
|> Map.merge(params)
|> Enum.reject(fn {_k, v} -> v == nil or v == "" end)
|> Map.new()
new_uri = Map.put(uri, :query, Plug.Conn.Query.encode(query))
%{new_uri | scheme: nil, authority: nil, host: nil} |> URI.to_string()
end
I put this in my app_web.ex file so that I could use it everywhere. Maybe that’s bad practice but it was common enough to warrant it.
