Read-only model, but be able to write through a wizard

I have a wizard that imports stock movements from suppliers, and the idea is that the user can only import them from the wizard and visualize them. If in model.access I leave only read I can not use the wizard, if in the view I put creatable=“false” it does not work because it is not a field of a one2many. The only alternative I can think of is that in the form all the fields are read only, but it is not the most elegant solution. I wanted to know if there is a more elegant way to do it.

Thanks in advance!

I think you will have all the pain to try to implement that because we designed Tryton to not have such workflow. We do not want users to create records through wizard but through standard forms.

Thanks for the reply!
