Error when using orm with useService in Odoo 17 about owl HOT 8 CLOSED

Hello, the issue is that you're not starting the services so useService cannot possibly work. Try following this guide which I recently wrote: https://www.odoo.com/documentation/master/developer/howtos/standalone_owl_application.html

I'm going to close this issue as it is not related to Owl itself but how to use Owl within Odoo. If it is a bug or feature request it should be an issue on the Odoo repo, if it's an issue with using using the code or the tutorial it should be an issue on the documentation repo

@sdegueldre You were right, I used mountComponent instead of mount to start the servers and the problem was solved.

thanks for your reply

Good luck

Hi @sdegueldre , thanks for your tips.
I'm using your proposal with mountComponent yet as I follow you tuto on Odoo doc it looks like mountComponent should be part of @web/env
AFAICS, there is no such method in @web/env , only in owl ...
Ah my bad, available in 17.0 not in v16.

Maybe using startWebClient in @web/start could be a good choice ?

Could you share your solution ?

hum, looks like it works for a owl applicaton.
What is the process to hook a component into a portal website page for example.
I've succeed in mouting the component but wahrerver the method, impossible to have services. UseService failed either with the v16 or v17 flavor with mountComponent.
Is it necessary to use OwlCompatibility because website still designed in old framework ?

If you want to be able to use useService your app's environment needs to contain the started services. In 17.0+ you can use mountComponent which does that for you automatically, but in lower versions you'll have to create your env yourself and start the services in that environment. You'll also need to make sure that the code for the services that you want to use and their dependencies are loaded in the correct assets bundle (assets_frontend for portal). I wouldn't recommend using startWebClient directly, as it does a few things that are specific to the actual webclient, but your starting code should do most of what startWebClient does.

In the website and portal, we already start the services and they can only be started once, so you'll have to reuse that env. I've replied to you on another issue about how to achieve this.

hi @HamidAbdalla123 , this issue is closed.
Moreover you didn't provides enough details so we can't identify if its an owl or Odoo issue.
Please open a proper issue.
