sequence in odoo 14

 

Add sequence to odoo object

 

we can add sequence in odoo 14 by following the example bellow 

 

now let us say that we have objects by the name "shilal.object" and we want to 

create sequence field for this objects as "S_O000001" , so to do that 

1/ add char field in this model as 

 

sequence  = fields.Char(string="Sequence")

 

 

2/add the function that will generate the value for this field as bellow

 

@api.model
    def create(self, vals):
       if vals.get('sequence', 'New') == 'New':
           vals['sequence'] = self.env['ir.sequence'].next_by_code(
               'shilal.object') or 'New'
       result = super(ShilalObject, self).create(vals)
       return result

3/ create the xml code for this sequence as bellow

<record id="shilal_object_sequence" model="ir.sequence"> // define sequence record
          <field name="name">Shilal Object Sequence</field> // define sequence name
          <field name="prefix">s_O </field>
          <field name="padding">6</field>
          <field name="code">input.fields</field>

</record>
