Creating Cron and Server Action in Odoo 11

For creation the Cron in odoo11, you will have also have to set model_id fields also as now in odoo11 ir.cron  have the delegate based relationship with ir.actions.server in which the  model_id is set to required.

Below code is explaining the delegate based relation between ir.cron and ir.actions.server.

class ir_cron(models.Model):
	_name = "ir.cron"
	_order = 'cron_name'

	ir_actions_server_id = fields.Many2one(
		comodel_name = 'ir.actions.server', 
		string = 'Server action',
		delegate = True,
		ondelete = 'restrict', 
		required = True
	)
	....
	....

class IrActionsServer(models.Model):
	_name = 'ir.actions.server'
	_table = 'ir_act_server'
	_inherit = 'ir.actions.actions'

	model_id = fields.Many2one(
		comodel_name = 'ir.model', 
		string = 'Model', 
		required = True, 
		ondelete = 'cascade',
		help = "Model on which the server action runs."
	)
	....
	....

For explaining the example I am creating a new a model (my.task) and registering  @api.model decorated method  cron_do_task.

class MyTask(models.Model):

	_name = "my.task"

	@api.model
	def cron_do_task(self):pass	
		....
		....

Now create data XML file for ir.cron  which should look like:

<record id="cron_do_task" forcecreate='True' model="ir.cron">
      <field name="name">Do -Task</field>
      <field eval="False" name="active"/>
      <field name="user_id" ref="base.user_root"/>
      <field name="interval_number">15</field>
      <field name="interval_type">minutes</field>
      <field name="numbercall">-1</field>
      <field name="model_id" ref="model_my_task"/>
      <field name="state">code</field>
      <field name="code">model.cron_do_task()</field>
</record>

Here the model_id is the model in which you want to execute the code section (for now @api.model decorated method cron_do_task ).

For creation the Server Action in odoo11 follow the below example:

Update your python code and add @api.multi decorated method ( server_do_action ):

class MyTask(models.Model):

	_name = "my.task"
	
	@api.model
	def cron_do_task(self):pass	
	
	@api.multi
	def server_do_action(self):pass	
		....
		....

and create data XML file for  ir.actions.server  as below:

    <record id="do_task_server" model="ir.actions.server">
          <field name="name">Do Action</field>
          <field name="type">ir.actions.server</field>
          <field name="model_id" ref="model_my_task"/>
          <field name="state">code</field>
          <field name="code">
              if records:
                  action = records.server_do_action()
          </field>
          <field name="binding_model_id" ref="model_my_task"/>
      </record>

Here model_id  is the model on which this action will show and  binding_model_id is the model which code section (records.server_do_action()) will execute on the click of server action.

That’s all for today. I hope this blog will help you. I’d be very grateful if you’d write your opinions, comments, and suggestions to keep the page updated and interesting.
