Question

I am using Odoo 10-e. I came from .net what i want to do is that i need to create my custom setting configuration file in Odoo like we have AppSettings file in asp.net where we set some static key values to use them in project. How to create that kind of file and how can i access that file in python code or xml files ?

Answer 1

Create a class that inherits from res.config.settings (so you can edit the record):
class farmacia_pedido_config_settings(models.TransientModel):
_inherit = 'res.config.settings'
_name = 'farmacia.config.settings'
lista_precios_defecto = fields.Many2one(
'product.pricelist',
string='Lista de precios por defecto')
Associate with the view:
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<record id="view_farmacia_configuration" model="ir.ui.view">
<field name="name">farmacia config settings</field>
<field name="model">farmacia.config.settings</field>
<field name="arch" type="xml">
<form string="Farmacia" class="oe_form_configuration">
<header>
<button string="Aplicar" type="object" name="execute" class="oe_highlight"/>
<button string="Cancelar" type="object" name="cancel" class="oe_link"/>
</header>
<field name="lista_precios_defecto" class="oe_inline"/>
</group>
</form>
</field>
</record>
<record id="action_farmacia_configuration" model="ir.actions.act_window">
<field name="name">Farmacia</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">farmacia.config.settings</field>
<field name="view_mode">form</field>
<field name="target">inline</field>
</record>
<menuitem id="menu_farmacia_config" name="Farmacia" parent="base.menu_config"
sequence="3" action="action_farmacia_configuration"/>
</data>
</openerp>
Save in a file accessing via python (this is uglier)
config = ConfigParser()
your_file = os.getenv("HOME")+os.path.sep+"your_file.conf"
if os.path.isfile(your_file):
config.read(your_file)
else:
raise models.except_orm(
'Error',
"File not found " + os.getcwd())
