Organization, Department and Employee hierarchy tree view | Odoo

In this article you will learn how to show employee hierarchy like tree data structure for manager and employee. By showing this you can define the role of individual employee within the organization. You can also manage the relationship between employees.

Tree Data Structure for Manager Employee Hierarchy

1. Below are the steps to create hierarchical structure for organization and employee.
2. Create hierarchical tree view
3. Create window action (ir.actions.act_window) or server action (ir.actions.server)
4. Create Menu that will call window or server action

In this article I am going to show you both of two methods (using window and server action). You can use one of them. The purpose of using server action is to get filtered records.

Hierarchical Tree view, Window & Server Action

	<record id="employee_hierarchy_tree_view" model="ir.ui.view">
	<field name="name">hr.employee.hierarchy.tree</field>
	<field name="model">hr.employee</field>
	<field name="field_parent">child_ids</field>
	<field eval="20" name="priority"/>
	<field name="arch" type="xml">
	<tree string="Employees" toolbar="True">
	<field name="name"/>
	<field name="company_id"/>
	<field name="department_id"/>
	<field name="work_phone"/>
	<field name="work_email"/>
	<field name="job_id"/>
	<field name="parent_id" invisible="1"/>
	</tree>
	</field>
	</record>
	<!--By using window action-->
	<record id="window_action_employee_hierarchy_tree" model="ir.actions.act_window">
	<field name="name">Employee Hierarchy Window Action</field>
	<field name="type">ir.actions.act_window</field>
	<field name="res_model">hr.employee</field>
	<field name="domain">[('parent_id','=',False)]</field>
	<field name="view_type">tree</field>
	<field name="view_id" ref="employee_hierarchy_tree_view"/>
	</record>
	<menuitem name="Employee | Organization Hierarchy" id="menu_employee_hierarchy_for_window_action" action="window_action_employee_hierarchy_tree" sequence="1"/>
	<!--By using server action-->
	<record id="server_action_employee_hierarchy_tree" model="ir.actions.server">
	<field name="name">Employee Hierarchy Server Action</field>
	<field name="condition">True</field>
	<field name="type">ir.actions.server</field>
	<field name="model_id" ref="model_hr_employee" />
	<field name="state">code</field>
	<field name="code">action=self.load_employee_hierarchy(cr, uid, context.get('active_ids', []), context=context)</field>
	</record>
	<menuitem name="Employee | Organization Hierarchy" id="menu_employee_hierarchy_for_server_action" action="server_action_employee_hierarchy_tree" sequence="1"/>

Server Action Code

	class HREmployee(models.Model):
	_inherit = 'hr.employee'
	@api.multi
	def load_employee_hierarchy(self):
	domain = []
	if self._context.get('params', False):
	params = self._context.get('params', False)
	if params.get('menu_id', False):
	raise ValidationError(
	"Attention:You are not allowed to access this page due to Security Policy. In case of any query, please contact ERP Admin or Configuration Manager.")
	else:
	return False
	view_id_tree = self.env['ir.ui.view'].search([('name', '=', 'hr.employee.hierarchy.tree')])
	user = self.env['res.users'].browse(self._uid)
	employee_pool = self.env['hr.employee']
	employee = employee_pool.search([('user_id', '=', user.id)])
	employee_ids = []
	if user.has_group('your_module.your_group_name_1'):
	# show all employees
	employee_ids = self.env['hr.employee'].search([]).ids
	if user.has_group('your_module.your_group_name_2'):
	# show user company employee
	employee_ids += self.env['hr.employee'].search([('company_id', '=', user.company_id.id)]).ids
	if user.has_group('base.group_user'):
	# show own record
	employee_ids += employee.ids
	employee_ids = list(set(employee_ids) - set([1]))
	return {
	'type': 'ir.actions.act_window',
	'res_model': 'hr.employee',
	'view_type': 'tree',
	'view_mode': 'tree',
	'view_id': view_id_tree.id,
	'views': [(view_id_tree[0].id, 'tree')],
	'target': 'current',
	'domain': [('parent_id','=',False),('id','in',employee_ids)]
	}
