Problem implementing web_timeline

1 Reply

5472 Views

Hello, I am using Odoo Community edition version 12 and I am currently trying to implement the timeline view from the web_timeline module, available here:

https://odoo-community.org/shop/product/web-timeline-2812?maturity=production%2Fstable

I have installed it, along with the Project timeline module:

https://odoo-community.org/shop/product/project-timeline-2093?search=project+timeline

The project timeline module works correctly, so since it depends on web_timeline, I am assuming that web_timeline was installed correctly.

I tried to add the timeline view to my own module, but this error pops up whenever I try to upgrade it:

Error:

Here is my full views.xml file:

<?xml version="1.0" encoding="utf-8"?>

<odoo>

<field name="name">Orders</field>

<field name="res_model">tms.order</field>

<field name="view_mode">tree,form,timeline</field>

</record>

<field name="name">Order Form</field>

<field name="model">tms.order</field>

<form>

<group>

</group>

<group>

</group>

</form>

</field>

</record>

<field name="name">Orders List</field>

<field name="model">tms.order</field>

<tree>

</tree>

</field>

</record>

<field name="model">tms.order</field>

<field name="type">timeline</field>

<timeline date_start="start_date"

date_stop="end_date"

string="Orders"

default_group_by="driver">

</timeline>

Assigned to:

</div>

</templates>

</field>

</record>

<field name="name">Order Search</field>

<field name="model">tms.order</field>

</search>

</field>

</record>

</odoo>

And the model that I'm trying to set into the timeline:

from odoo import models, fields, api

class Order(models.Model):

_name = 'tms.order'

company_id = fields.Many2one('res.company',string = 'Client')

description = fields.Text()

start_date = fields.Date('Start Date')

end_date = fields.Date('End Date')

start_location = fields.Char()

end_location = fields.Char()

driver = fields.Many2one('hr.employee',string = 'Driver')

vehicle = fields.Many2one('fleet.vehicle')

I noticed that in the error message, there's a <data> tag somehow put in automatically by Odoo, it's right under the "arch" field tag. Can this be the cause of the problem? I can't seem to find the solution. Thank you for your help!

Oops, I forgot to add web_timeline to dependencies in the manifest dependencies. It works now.
