No results when i try to create custum dashboard in odoo
I create a new module for custom dashboard in odoo following this tutorial : link
but always i found the same result is false, here is my code :
The result :
** model.py : **
create a dashboard model (kanban.count) and add some filed
class KanbanCount(models.Model)
_name = "kanban.count"
color = fields.Integer(string='Color Index')
name = fields.Char(string="Name")
#api.one
def _get_count(self):
quotations_count = self.env['sale.order'].search(
[('sate', '=', 'draft')])
orders_count = self.env['sale.order'].search(
[('sate', '=', 'sales_order')])
orders_done_count = self.env['sale.order'].search(
[('sate', '=', 'done')])
self.orders_count = len(orders_count)
self.quotations_count = len(quotations_count)
self.orders_done_count = len(orders_done_count)
orders_count = fields.Integer(compute = '_get_count')
quotations_count = fields.Integer(compute= '_get_count')
orders_done_count = fields.Integer(compute= '_get_count')
The Kanban View :
Create a kanban view of this above-created model
<record model="ir.ui.view" id="count_kanban_form_view">
<field name="name">Count form</field>
<field name="model">kanban.count</field>

Answer 1

<record id="kanabn_count_dashbord" model="kanban.count">
<field name="name">Kanban Dashboard</field>
</record>

Answer 2

Remove the "span" tag with a "t" tag.
For example:
<span t-name="kanban-box">
Simply replace above line as(closing tags also):
<t t-name="kanban-box">
try, i hope it's will be work
