Hello Marco Duran,

I understand your question and yes the code is changed in V15.

I tried adding a button on sale order list view and I could achive it using below code.

Js file code:

function ccButton() {
if (this.$buttons) {
var self = this;
this.$buttons.on('click', '.o_button_custom', function () {
self.do_action({
name: 'Generate Leads',
type: 'ir.actions.act_window',
res_model: 'sale.order',
target: 'new',
views: [[false, 'form']],
});
});
}
}


var cListController = ListController.extend({
willStart: function() {
var self = this;
// var ready = self.buttons_template = 'CustListView.buttons';
var ready = this.getSession().user_has_group('sales_team.group_sale_manager')
.then(function (is_sale_manager) {
if (is_sale_manager) {
self.buttons_template = 'CustListView.buttons';
}
});
return Promise.all([this._super.apply(this, arguments), ready]);
},
renderButtons: function () {
this._super.apply(this, arguments);
ccButton.apply(this, arguments);
}
});


var CustListView = ListView.extend({
config: _.extend({}, ListView.prototype.config, {
Controller: cListController,
}),
});

viewRegistry.add('cust_tree', CustListView);

Xml file code :

sale.order.tree
sale.order

primary


cust_tree

Hello Jainesh Shah, thank you for the reply.

Checking your answer, we still could not render the button on the page. We found out that part of the problem with the render is a tag named t-name. With this tag, the button would not render:

t t-extend="ListView.buttons" t-name="HrExportListView.buttons"
    t t-jquery="button.o_list_export_xlsx" t-operation="after"
        button type="button" class="oe_export_ins">INS    /t
/t

But without it, it does:

t t-extend="ListView.buttons"
    t t-jquery="button.o_list_export_xlsx" t-operation="after"
        button type="button" class="oe_export_ins">INS    /t
/t

Although the button is being rendered, there’s no reaction when you click it. The Javascript is instantiated in the DOM but the content does not work properly.

In the Javascript, when we print the ListController and ListView instances, the console print out the following message:

ƒ Class(){
    if(this.constructor!==OdooClass){
        throw new Error("You can only instantiate objects with the 'new' operator");
    }
    this._super=null;
    if(!initializing&&this.init){
        var ret=this.init.apply(this,arguments);
        if(ret){
            return ret;
        }
    }
    return this;
}

We tried checking everything but no success. Anyone know why this happens and where could be the problem with my implementation? The Odoo version we are using is 15.0-20220110 (Community Edition).
