TypeError: instance.web.core is undefined - odoo

Question

I can not add new action in Odoo9
openerp.pr_finance = function(instance, local) {
var _t = instance.web._t, _lt = instance.web._lt;
var QWeb = instance.web.qweb;
var Widget = instance.web.Widget;
var core = instance.web.core;
var data = instance.web.data;
var session = instance.web.session;
var utils = instance.web.utils;
var Model = instance.web.Model;
var ControlPanelMixin = instance.web.ControlPanelMixin;
instance.web.ListView.include({
init: function() {
//console.log('JS loaded');
this._super.apply(this, arguments);
},
render_buttons: function(data) {
console.log('JS loaded load_list');
console.log(data);
this._super(data);
if (this.$buttons) {
this.$buttons.find('.oe_my_button').click(this.proxy('do_import_file_csv_ya_tz')) ;
}
},
do_import_file_csv_ya_tz: function () {
console.log('123123123123123123 ooops....');
this.do_action(
{
name: _t("IMPORT MY FILE"),
type: "ir.actions.client",
tag: 'import_csv',
params: {}
}
);
}
});
var import_csv_yandex = Widget.extend({
template: 'ImportViewYaTC',
start: function () {
console.log("ImportViewYandexTC page loaded");
},
});
var DataImport = Widget.extend(ControlPanelMixin, {
template: 'ImportView',
init: function(parent, action) {
console.log("init ImportView");
this._super.apply(this, arguments);
action.display_name = _t('Import a File');
},
start: function () {
console.log("ImportView page loaded");
},
});
console.log("core.action_registry.add");
try {
instance.web.core.action_registry.add('import_csv', DataImport);
} catch (err) {
console.log(err);
}
console.log("core.action_registry.add - OK!");
}
I received error here:
instance.web.core.action_registry.add('import_csv', DataImport);
Error:

Why this variable is undefined?

Answer 1

You need to use require to get the variables of the env: ie.
odoo.define('yourmodulename.pr_finance', function (require) {
"use strict";
var core = require('web.core');
});
a good place to look at to understand inheritance in odoo is the github.com/oca/web repo.
