[tryton] Write access to field where the model is read only?

[Steven Lightfoot]

I have a module that displays some calculations based on a selection field. It’s a reference module only, I don’t want a user to add or delete data. I have preloaded the table with data.

If I make the model read only, I can’t change the selection to do the calculations but if I allow write access to the model then the option to save is available.

Is there a way of disabling the save, create but still allowing a user access to the selection field?

No, access rights are layers that appends on each other, so you must
have the right on each layers that have effectively the right.

Thanks for the clarification
