i as wondering what are the left and right column in the model account_account and if there is an impact somewhere ?
They are used for MPTT: Fields — Tryton server
i already read that written on klyngon would do the same for me ,-)
When i create line by sql… what happens if i do not give values (there will be a reconstruct ? so not a problèm ?
it is explained in the warning of the left attribute:
The MPTT Tree will be rebuild on database update if one record is found having left or right field value equals to the default or NULL.
