Models not showing

I created a new module on tryton similar to health_lab. I manage to activate the module with no issue. The module menu show up but the models can’t be found. Can i know what’s the issue?

Probably the problem is that your xml record is not registered on tryton.cfg so not loaded on the database.

i don’t think it is the xml file the problem because i can see all the menus i added in the xml file.
Just that the models link to the menu can’t be found.
I checked in the administration and the models are you presents

We can not help if you do not share your code, not what you did in your module.

Did you register the class with Pool.register in the register method of the module?
