Rationale ========= Since v8, the `display_name` field is present on all models. By default, `display_name` uses `name_get` which has pretty much the same purpose (return record name used by the web client). Gradually, many (backend) developers (and the ORM: https://github.com/odoo/odoo/commit/6da1c3ac4c036eac289597602976538e243cb939) started using `display_name` (more convenient than `record.name_get()[0][1]`) but it still had the `name_get` override. It becomes more complex than necessary and poeple start to misunderstand the two (and sometimes override both, leading to inconstiencies between `display_name`/`name_get`). To simplify the ORM and the API, we decided to keep only one of them, the `display_name` field: - It is much more convenient from a backend point of view (`record.name_get()[0][1]` vs `record.display_name`) - It is cached during the same transaction (and invalidated if its dependencies change) - It can be overridden like any other compute field (override `_compute_display_name` with any extra dependencies) - `name_get` is replaced by `read(['display_name'])` (API perceptive), which can actually be more efficient (if `display_name`'s depends are correct, the ORM will only fetch the fields it needs instead of every prefetchable field) Changes ======= - Deprecates `name_get` for the v17 and based the method on `display_name` (the opposite of before) - Converts all usage of `name_get` - Overrides of `name_get` are now overrides of `_compute_display_name` - For `res.partner`, rename the field store `display_name` into `complete_name` because `display_name` context-dependent and it makes no sense to have a compute store that is context-dependent. - Previously, it was possible to return multiple names for the same record with `name_get`, but it was tricky and most of the usage of this `name_get` didn't take this into account. The only example of this is the `name_get` of `product.product` (now use `", ".join(<names>)`). Part-of: odoo/odoo#122085
