I'm looking for a way to override some openerp web js core functions such as "on_logout".
The docs lack of instructions (as you can see in my post) and the helloworld module tells you that you can do it like
openerp.web_hello = function(openerp) {
openerp.web.SearchView = openerp.web.SearchView.extend({
init:function() {
this._super.apply(this,arguments);
this.on_search.add(function(){console.log('hello');});
}
});
// here you may tweak globals object, if any, and play with on_* or do_* callbacks on them
openerp.web.Login = openerp.web.Login.extend({
start: function() {
console.log('Hello there');
this._super.apply(this,arguments);
}
});
};
In my module I'm doing this:
openerp.mytest = function(openerp){
openerp.web.WebClient = openerp.web.WebClient.extend({
on_logout: function() {
alert('mine');
[...]
},
});
}
I know js is loaded since putting an alert outside this definition works.
What's wrong here?
That's a bit of a special issue since you want to alter the prototype (the class, if you will) of an object which is already instantiated (a WebClient instance is the root of the system, so it's probably already there by the time your code is loaded, therefore creating a new WebClient "class" won't alter the existing instance).
In that case, you can't replace the class with a subclass, you have to re-open the class (in a manner similar to Ruby), for that there is an include
method on class objects, which should work:
openerp.mytest = function(openerp) {
openerp.web.WebClient.include({
on_logout: function() {
alert('mine');
this._super.apply(this, arguments);
}
});
}
(as in Ruby, this._super
is bound to the method you're replacing, if any, for in-place class alterations)
If you check the view_list_editable.js implementation file, it provides examples of that since it needs to reopen and alter the listview's code in order to add editability.
