You need to extend ListView.buttons QWEB template.
Define a QWEB template under static/src/xml which adds the button:
<?xml version="1.0" encoding="utf-8"?>
<template xml:space="preserve">
<t t-extend="ListView.buttons">
<t t-jquery="button.oe_list_add" t-operation="after">
<button t-if="widget.dataset.model == 'model_name'" class="oe_button oe_my_button oe_highlight" type="button">My Button</button>
</t>
</t>
</template>
Use JavaScript to define the logic of the button ( create a file under static/src/js):
openerp.module_name = function(instance){
instance.web.ListView.include({
load_list: function(data) {
this._super(data);
if (this.$buttons) {
this.$buttons.find('.oe_my_button').off().click(this.proxy('do_the_job')) ;
}
},
do_the_job: function () {
this.do_action({
name: _t("View name"),
type: "ir.actions.act_window",
res_model: "object",
domain : [],
views: [[false, "list"],[false, "tree"]],
target: 'new',
context: {},
view_type : 'list',
view_mode : 'list'
});
}
});
}
Define a new view that will add module assets (module_name_view.xml):
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<template id="assets_backend_module_name" name="module_name assets" inherit_id="web.assets_backend">
<xpath expr="." position="inside">
<script type="text/javascript" src="/module_name/static/src/js/script.js"></script>
</xpath>
</template>
</data>
Edit __openerp__.py and add the following sections:
'data': [
'module_name_view.xml',
...
],
'qweb': ['static/src/xml/*.xml'],
