How to Create service in odoo10

On Ubuntu 16.04, this is how you create a service for Odoo10:

[Unit]
Description=Odoo
Documentation=http://www.odoo.com/
[Service]
# Ubuntu/Debian convention:
Type=simple
User=odoo
ExecStart=/opt/odoo10/odoo-bin -c /etc/odoo-server.conf
[Install]
WantedBy=default.target

You put this in /etc/systemd/system and I called my file odoo10.service so you can then do:

sudo systemctl start odoo10.service (starts service)
sudo systemctl stop odoo10.service (stops service)
sudo systemctl restart odoo10.service (restarts Service)
sudo systemctl status odoo10.service (status of service)
sudo systemctl enable odoo10.service (starts service at boot)
sudo systemctl disable odoo10.service (disables service at boot)

ValueError Expected singleton in Odoo

Expected Singleton:

Class methods required single invoking object (Single Browsable Record) to invoke the method and suppose it will call by multiple invoking objects (Browsable Recordsets) then method is not able to identify for which object it should process, therefore it will raise an error Expected Singleton.

New API decorator is used to define method calling pattern whether methods allows only single object or multiple objects to invoke this method.


For Example:


if self.location_id:     #face ValueError Expected singleton because self contains multiple recordset.

    ########

Need to change with following:

for warehouse in self:

    if warehouse.location_id:

        ########


@api.one

This decorator loops automatically on Records of RecordSet for you. Self is redefined as current record

Note:

Caution: the returned value is put in a list. This is not always supported by the web client, e.g. on button action
methods. In that case, you should use @api.multi to decorate your method, and probably call self.ensure_one() in
the method definition.

@api.multi

Self will be the current RecordSet without iteration. It is the default behavior (multiple browsable objects). Methods which returns non premitive type data(list, dictionary, function) must be decorated with @api.multi

@api.model

This decorator will convert old API calls to decorated function to new API signature. It allows to be polite when
migrating code. Self does not contain any record/recordset in methods which are decorated by this decorator.

So simply call like this

self.env['model_name'].method_name(arguments)

one2many, many2many, many2one field in openerp

In OpenERP/Odoo, we have one2many and many2many datatype field. For add, update, delete we have some trick to link with record, which are listed below.

1. (0, 0,  { values })    link to a new record that needs to be created with the given values dictionary

2. (1, ID, { values })    update the linked record with id = ID (write *values* on it)

3. (2, ID)                     remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)

4. (3, ID)                     cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)

5. (4, ID)                     link to existing record with id = ID (adds a relationship)

6. (5)                          unlink all (like using (3,ID) for all linked records)

7. (6, 0, [IDs])             replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)
