Custom code: Can clicking on a Task with Subtasks (in Kanban View) open another Kanban with the Subtasks?

Hi,

I have a question about how to manage a project requirement:

A client uses the projects module in Odoo 16 with tasks and subtasks. They asked me as a requirement that, in the task kanban, when clicking on a task that has subtasks, instead of opening the form with the task data, a Kanban with the subtasks of the parent task should reopen.

I understand that this requirement must be implemented with Owl, but I can't get it to work. In fact, I can't inherit the Kanban view from the tasks and change the on-click behavior to change the functionality. Do you have any examples of how to inherit a Kanban and change the on-click using Owl?

Thank you

Best regards.

Hello Santiago Carbonell Forment,

You cannot inherit the KanbanRecord template directly because it is an OWL template.

This means you cannot inherit it using a regular: <odoo><template inherit_id="..."></template></odoo> since that only works for backend QWeb views.

✅ Instead, you can either directly replace the template or patch the existing onClick function.

I’ve attached the code which directly opens the Kanban view of Subtasks, you just have change the module name.

```import { patch } from '@web/core/utils/patch';

import { KanbanRecord } from '@web/views/kanban/kanban_record';

export const CANCEL_GLOBAL_CLICK = ["a", ".dropdown", ".oe_kanban_action", "[data-bs-toggle]"].join(

","

);

patch(KanbanRecord.prototype, 'my_module.KanbanRecord', {

onGlobalClick(ev) {

const { archInfo, forceGlobalClick, openRecord, record } = this.props;

console.log("Called", record.data)

if (record.data.child_text != false) {

this.env.services.action.doAction({

type: 'ir.actions.act_window',

name: 'Subtasks',

res_model: 'project.task',

domain: [['parent_id', '=', record.resId]],

view_mode: 'kanban',

views: [[false, 'kanban']],

target: 'current',

});

}

else {

if (ev.target.closest(CANCEL_GLOBAL_CLICK)) {

return;

}

if (!forceGlobalClick && archInfo.openAction) {

this.action.doActionButton({

name: archInfo.openAction.action,

type: archInfo.openAction.type,

resModel: record.resModel,

resId: record.resId,

resIds: record.resIds,

context: record.context,

onClose: async () => {

await record.model.root.load();

record.model.notify();

});

} else if (forceGlobalClick || this.allowGlobalClick) {

openRecord(record);

}

}); ```

⚠️ Please note: this code is only for reference purposes.

If you patch the onClick method, it will change the behavior across all kanban views in Odoo, so you need to handle it carefully and test every case where a kanban view is used.

❓ If you implement this then how user will open the parent task?

Hello Sufiyan Muzaffar Shaikh

I haven't written to you before because I had to take a rushed Owl course in Odoo because understanding this whole new environment is complicated, and I wanted to understand what you sent me.

Congratulations! This is by far the best answer I've received, and now I think I understand. In fact, the problem isn't the projects module, but rather that the onclick is actually in the base web module, and it's from there that you have to inherit. Also, you have to change that onGlobalClick method, which I've been looking for, and not just onclick. It's huge and indeed complicated to update because it actually affects many modules such as CRM, Project, HR, Employee, etc.

I don't know if there's a simple way with parent or super to have the onGlobalClick inherit everything from the parent module, and I just add my code, although I don't think it would work well.

Thinking about it, it might be simpler to use doubleClick or rightClick instead of onGlobalClick, which I don't think are used, and detect the model using, for example, record.data.tag_ids.parentRecord.resModel, where I can see if it's a project or a task and decide based on that.

I'm a little new to Owl. Do you know if I can add a rightClick event to do this?

Thank you very much.

Here,

Create a JS File : project_task_kanban_patch.js

/** @odoo -module **/

import { patch } from  "@web/core/utils/patch" ;
 import { KanbanRecord } from  "@web/views/kanban/kanban_record/kanban_record" ;
 import { useService } from  "@web/core/utils/hooks" ;

patch ( KanbanRecord . prototype , {
     setup ( ) {
         super . setup ();
         this . action = useService ( "action" );
    },

    async  onRecordClick ( ev ) {
         const record = this . props . record . data ;

        // If task has subtasks, open them in Kanban 
        if ( this . props . record . model === "project.task" && record. child_ids . length > 0 ) {
            house. preventDefault ();
             await  this . action . doAction ({
                 type : "ir.actions.act_window" ,
                 name : `Subtasks of ${record.name} `,
                 res_model : "project.task" ,
                 view_mode : "kanban,form" ,
                 domain : [[ "id" , "in" , record. child_ids ]],
                 context : { default_parent_id : record. id },
                 target : "current" ,
            });
            return ;
        }

        // Otherwise, use default behavior 
        await  super . onRecordClick (home);
    },
});

Include in Manifest

In your __manifest__.py :

"assets" : {
     "web.assets_backend" : [
         "your_module/static/src/js/project_task_kanban_patch.js" ,
    ],
},

Ensure child_ids is in the Kanban view

Add this in XML:

<record id = "project.task.kanban.view.inherit"  model="ir.ui.view">
     <field  name = "model" >project.task </field>
     <field  name = "inherit_id"  ref ="project.view_task_kanban"/>
     <field  name = "arch"  type = "xml">
         <field name = "name"  position = "before">
             <field name = "child_ids"/>
         </field>
     </field>
 </record>

i hope it is usefull
