This commit implements a new way to monkey-patch ES6
classes (for instance, Owl Components).
Usage
-----
odoo.module('module.BaseClass', function (require) {
const patchMixin = require('web.patchMixin');
// Define your class as usual
class BaseClass {
constructor() {
this.foo = 'foo';
}
bar() {
console.log(this.foo);
}
}
// but export it like this to have a "patchable" version
return patchMixin(BaseClass);
});
odoo.module('module.Patch', function (require) {
// imports the "patchable" version
const BaseClass = require('module.BaseClass');
BaseClass.patch('key', T =>
class extends T {
constructor() {
super();
this.foo = 'patched foo';
}
bar() {
super.bar();
console.log('patched bar()');
}
}
);
});
odoo.module('module.instance', function (require) {
// imports the "patchable" version
const BaseClass = require('module.BaseClass');
const obj = new BaseClass();
obj.bar();
// if module.patch is loaded before this module the patch
// will be apply and calling obj.bar() will log:
// patched foo
// patched bar()
// You can unpatch a patchable class
BaseClass.unpatch('key');
});
