Protactively checking exists() seems unnecessary, it's likely that the widget would be called on an empty recordset but seems very unlikely that it'll be called on a missing record. The commit which added the exists() call performs significant refactoring/rewrite and doesn't explain why this exists() call would be useful. Since exists is not cached and qweb field converters are not batched, saves a large number of queries when formatting a series of addresses e.g. with 99 hr.job, /jobs goes from ~170 queries and ~100ms spent in SQL to ~70 queries and ~60ms spent in SQL. Though the total performance improvement is very limited as even with odoo/odoo#32985 the endpoint takes ~700ms (with the aforementioned 99 hr.job visible to the current user). closes odoo/odoo#32986 Signed-off-by: Xavier Morel (xmo) <xmo@odoo.com>
