Odoo 9 how to append custom view template into existing views?

Question

I'd like to append a template in between KanbanView.buttons and KanbanView.Group to show description field in "project.project" model when I view "project.task" kanban view.

I guess there should be somewhere to append those templates into kanban view but unfortunately, I cannot find it.

What I did is

I created a custom template layouts.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <templates>
            <t t-name="eric-kanban-view">
                <div>This is Eric's kanban view</div>
            </t>
        </templates>
    </data>
</openerp>

and I'd like to add the template to "project.view_task_kanban" to locate above kanban view project.xml

<record id="project_task_custom_kanban" model="ir.ui.view">
    <field name="inherit_id" ref="project.view_task_kanban"/>
    <field name="model">project.task</field>
    <field name="arch" type="xml">
        <xpath expr="//templates" position="before">
            <t t-call="eric-kanban-view"/>
        </xpath>
    </field>
</record>

    'version' : '1.1',
    'author' : "Eric Lee",
    'description': 'eric\'s Project customized module',
    'installable' : True,
    'data' : [
        'project.xml',
    ],
    'depends' : [
        'project',
    ],
    'qweb': [
        'static/src/xml/layouts.xml',
        'static/src/xml/project.xml',
    ],
}

But nothing happened.

Below is the layout I want

Answer 1

You need to create a widget by extending kanbanView.

Here is the example:

Here is the sample code.

static/src/xml/template.xml

<template id="template" xml:space="preserve">

 <t t-name="kanban.sample_header">
   <div class="sample_header" style="width:100%;height:50px;background-color:#fff;">
     <h2>Sample header</h2>
  </div>
</t>
</template>

static/src/js/sample.js

odoo.define('kanban.sample_dashboard', function (require) {
"use strict";


var core = require('web.core');
var formats = require('web.formats');
var Model = require('web.Model');
var session = require('web.session');
var KanbanView = require('web_kanban.KanbanView');

var QWeb = core.qweb;

var _t = core._t;
var _lt = core._lt;

var sampleHeader = KanbanView.extend({
  display_name: _lt('Dashboard'),
  icon: 'fa-dashboard',
  fetch_data: function() {
      // Overwrite this function with useful data
      return $.when();
  },
  render: function() {
      var super_render = this._super;
      var self = this;

      return this.fetch_data().then(function(result){
          self.show_demo = result && result.nb_opportunities === 0;

          var sales_dashboard = QWeb.render('kanban.sample_header', {
              widget: self,
              show_demo: self.show_demo,
              values: result,
          });
          super_render.call(self);
          $(sales_dashboard).prependTo(self.$el);
      });
  },

});
core.view_registry.add('sample_header', sampleHeader);

return sampleHeader;

})

view.xml

<odoo>
 <data>


<template id="assets_backend" name="sample_header" inherit_id="web.assets_backend">
    <xpath expr="." position="inside">
        <script type="text/javascript" src="/kanban/static/src/js/sample_js.js"></script>
    </xpath>
</template>


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

      <xpath expr="//kanban" position="attributes">
        <attribute name='js_class'>sample_header</attribute>

      </xpath>
    </field>
</record>
 </data>
 </odoo>

Hope this will help you.
