[IMP] web_timeline - support multiple group-by levels and allow to group by m2m field

[cuongnmtm]

Allowing to add multiple group-by levels

Test cases:

• group by one field (group by m2o, selection, integer, m2m, date, ...)
• group by multiple fields
• group by 0 field: back to default group by
• create a new record
• drag and drop record to update
• click on the group by to view the group by record detail
• when group by m2m field, record is displayed multiple times if linked to multiple m2m records
• when drag and drop, the value of the m2m field should not be updated as there is no best way to handle this
• when creating a new record, set the default value for all grouped fields
• handle group by non-relation fields: click on the group of selection or char field do not popup record form view to avoid error.
• dependency_arrow

Hi @tarteo,
some modules you are maintaining are being modified, check this out!

[pedrobaeza]

Can you please put an screenshot of the feature?

[cuongnmtm]

@pedrobaeza I have included a screenshot of the feature in the PR description.

[pedrobaeza]

Great improvement!

[tarteo]

Awesome!
I get an error when I quickly add and remove a group (by double clicking). However if I click normally I don't get an error. There's probably a race condition somewhere

Error (I have assets debugging enabled):
UncaughtPromiseError > TypeError Uncaught Promise > Cannot read properties of undefined (reading 'relation') TypeError: Cannot read properties of undefined (reading 'relation') at Class.split_groups (http://localhost:8069/web/assets/debug/web.assets_backend.js:190546:71) (/web_timeline/static/src/js/timeline_renderer.js:509)

@tarteo I cannot reproduce your issue, but I found another related defect and fixed it (error when clicking on the group when group by non-relation field). Could you please help to check again? Thanks.

And other things had been done (inthe description).

For non-technical who wish to test this feature, you can use the XML view arch below to create a timeline view for the project model and modify the project window action to include the timeline view mode for testing.

<timeline date_start="date_start" date_stop="date" string="Projects" default_group_by="user_id,partner_id,privacy_visibility" mode="week" event_open_popup="true" stack="true">
    <field name="user_id"/>
    <field name="privacy_visibility"/>
    <field name="tag_ids"/>
    <field name="name"/>
    <templates>
        <t t-name="timeline-item">
            <div t-att-title="record.name">
                <small>
                    <div>
                      <span>
                          <t t-esc="record.name"/>
                      </span>
                    </div>
                    <div>
                      PM:
                      <span>
                          <t t-esc="record.user_id[1]"/>
                      </span>
                    </div>
                  
                </small>
            </div>
        </t>
    </templates>
</timeline>

We added on the scheduled actions the timeline view as demo data for demonstration purposes without requiring extra modules. Maybe you can modify that demo view to showcase this feature.

I missed that. Thanks.

Awesome @cuongnmtm. It would be great to update the version of the addon.

No, that's done on merge by the bot, when we issue the command.
