You need to replace the function and then call _super(). Include your method in the class which implements this function. A similar question is posted HERE with a specific implementation which has been tested. My below example has not been tested fully. Remember to install your addon and update it to see your changes.

var core = require('web.core');
var QWeb = core.qweb;
var thread = require('mail.ChatThread');
var ORDER = {
DESC: -1,
ASC: 1,
}
thread.include({
render: function (messages, options) {
console.log("TEST");
var msgs = _.map(messages, this._preprocess_message.bind(this));
if (this.options.display_order === ORDER.DESC) {
msgs.reverse();
}
options = _.extend({}, this.options, options);
// Hide avatar and info of a message if that message and the previous
// one are both comments wrote by the same author at the same minute
var prev_msg;
_.each(msgs, function (msg) {
if (!prev_msg || (Math.abs(msg.date.diff(prev_msg.date)) > 60000) || prev_msg.message_type !== 'comment' || msg.message_type !== 'comment' || (prev_msg.author_id[0] !== msg.author_id[0])) {
msg.display_author = true;
} else {
msg.display_author = !options.squash_close_messages;
}
prev_msg = msg;
});
this.$el.html(QWeb.render('mail.ChatThread', {
messages: msgs,
options: options,
ORDER: ORDER,
}));
},
});
});
Ensure you include the file declaring your js in your __openerp__.py file.
