Odoo8 - Need a example of ir.actions.server executing multiple actions one after the other - odoo-8

Question

In a wizzard view I have a button returning pdf report in a 'ir.action.act_url'. It works fine. Problem is that after the pdf appeared I would like the wizzard window to be closed automatically. To do this I can return close_window dict.
Separately this two 'return' work fine.
I would like to execute two actions, one after another. I found that this is possible using ir.action.server with multi attribute.
Unfortunately I couldn't find even one example.
close_window = {'type': 'ir.actions.act_window_close'}
final_report = {
'type': 'ir.actions.act_url',
'url': '/web/binary/saveas?model=ir.attachment&field=datas&
filename_field=name&id=' + str(file.id),
'target': 'self',
}
return final_report

Answer 1

Check the ir_actions tests that ship with Odoo, they might be able to help you in the right direction.
base/tests/test_ir_actions.py
def test_60_multi(self):
cr, uid = self.cr, self.uid
# Data: 2 server actions that will be nested
act1_id = self.ir_actions_server.create(cr, uid, {
'name': 'Subaction1',
'sequence': 1,
'model_id': self.res_partner_model_id,
'state': 'code',
'code': 'action = {"type": "ir.actions.act_window"}',
})
act2_id = self.ir_actions_server.create(cr, uid, {
'name': 'Subaction2',
'sequence': 2,
'model_id': self.res_partner_model_id,
'state': 'object_create',
'use_create': 'copy_current',
})
act3_id = self.ir_actions_server.create(cr, uid, {
'name': 'Subaction3',
'sequence': 3,
'model_id': self.res_partner_model_id,
'state': 'code',
'code': 'action = {"type": "ir.actions.act_url"}',
})
self.ir_actions_server.write(cr, uid, [self.act_id], {
'state': 'multi',
'child_ids': [(6, 0, [act1_id, act2_id, act3_id])],
})
# Do: run the action
res = self.ir_actions_server.run(cr, uid, [self.act_id], context=self.context)
# Test: new partner created
pids = self.res_partner.search(cr, uid, [('name', 'ilike', 'TestingPartner (copy)')]) # currently res_partner overrides default['name'] whatever its value
self.assertEqual(len(pids), 1, 'ir_actions_server: TODO')
# Test: action returned
self.assertEqual(res.get('type'), 'ir.actions.act_url')
# Test loops
with self.assertRaises(except_orm):
self.ir_actions_server.write(cr, uid, [self.act_id], {
'child_ids': [(6, 0, [self.act_id])]
})
Have not done it myself, but it looks like you have to specify that it is a multi action, and specify the child_ids actions to be executed.
Also keep in mind that according to the docs (https://www.odoo.com/documentation/8.0/reference/actions.html):
multi
Executes multiple actions one after the other. Actions to execute are
defined via the child_ids m2m. If sub-actions themselves return
actions, the last one will be returned to the client as the multi's
own next action

According to #dgeorgiev I wrote further code. I managed to create server actions and individually this actions are able to return pdf file or close the window. But I couldn't combine these two return's. See below:
# first server action returning pdf
ir_actions_server = self.env['ir.actions.server']
act1_id = ir_actions_server.create({
'type': 'ir.actions.server',
'name': 'divided_package_labels',
'sequence': 1,
'model_id': self.id,
'state': 'code',
'code': 'action = {"type": "ir.actions.act_url", "url": "/web/binary/saveas?model=ir.attachment&field=datas&filename_field=name&id= %s", "target": "new"}' % str(file.id),
})
# second server action closing window
act2_id = ir_actions_server.create({
'type': 'ir.actions.server',
'name': 'Close_sale.package.wizard',
'sequence': 2,
'model_id': self.id,
'state': 'code',
'code': 'action = {"type": "ir.actions.act_window_close"}'
})
# server action for combining two previously described
act_id = ir_actions_server.create({
'type': 'ir.actions.server',
'name': 'TestAction',
'condition': 'True',
'model_id': self.id,
'state': 'multi',
# 'child_ids': [(6, 0, [act1_id.id])] # return pdf
# 'child_ids': [(6, 0, [act2_id.id])] # close window
'child_ids': [(6, 0, [act1_id.id, act2_id.id])] # close window, no pdf file
})
print act_id, act1_id, act2_id
print "act_id.child_ids", act_id.child_ids
# shows that the relations are properly made
# run
return act_id.run()
Probably there is a small mistake, but I couldn't find it.
