Please explain the mean of below stattements and state the difference between them. i go through forum posts but not got clear idea from those and doc also not mention those stuffs.
i got below code from sale_security.xml file
<?xml version="1.0" encoding="utf-8"?> <openerp> <data noupdate="0">
The noupdate parameter is used to indicate if the values in the xml file must be re-imported when a module in updated.
For example, if we have a file with demo datas and we use noupdate="1", if we delete a demo record and update the module, the deleted data not will be imported again. With noupdate="0", instead, the record will be reimported again if it doesn't exist in the db.
Francesco, the example you gave is not 100% correct. This behavior is actually driven by 2 things: the noupdate flag on the
data element, and the
forcecreate attribute of each record. The latter defaults to "True" and determines whether a record that has been deleted will be re-created during an update, even if it is in a
noupdate section. So by default
noupdate will prevent synchronizing module data at each update (so you can customize it), but will not prevent the re-creation of deleted data. Set forcecreate="0" on individual records if you want that behavior as well.
