Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I want to retrieve the current configuration of a module that uses the class config.settings to store the configuration. But how can we retrieve the current state of the configuration ? From what I saw, each time the configuration is updated, a new line is inserted in the database. So doing something like
self.pool.get('sale.config.settings').browse(cr,uid,ids)[0]
won't work because I need to fetch the current state, not the first configuration stored. What is the correct way of doing it ?
In fact I realized that the class res.config.settings is of type osv_memory meaning that lines in the database are not kept ! The correct way of using this class is to name fields 'default_xxx'. The execute method will store the default value in the ir_values table so that we can retrieve them by calling the default_get method on the model object. Here is an example :
class mysql_config(osv.osv_memory):
_inherit = 'res.config.settings'
_name = 'mysql.config.settings'
_columns = {
'default_mysql_host' : fields.char('MySQL Host', default_model='mysql.config.settings')
}
Here is a good tutorial on how doing this: http://ludwiktrammer.github.io/odoo/custom-settings-odoo.html
Emanuel,
While doing the search, try to use the order id desc.
IDS = self.pool.get('sale.config.settings').search(cr, uid, [], order='id desc', limit=1)
result_obj = self.pool.get('sale.config.settings').browse(cr,uid,IDS[0])
Thanks.

Your solution works, thanks. However when the settings were not changed (default settings), there is no row in the table. Then, how do we read the default configuration ?
