Odoo 9.如何覆盖表单小部件? [英] Odoo 9. How to override form widgets?
问题描述
我使用odoo 9 。在系统中存在 render_value 方法,用于每种类型的字段:
I work with odoo 9. In the system exists render_value method for each type of field:
/odoo/addons/web/static/src/js/views/form_widgets.js
/odoo/addons/web/static/src/js/views/form_relational_widgets.js
如何为所有表单使用我的自定义方法 render_value (例如在 FieldChar 中)?以及如何为一个表单或一个模块使用特定的 render_value ?
How I can use my custom method render_value(for example in FieldChar) for all forms? And how I can use specific render_value for one form or one module?
我在模块中创建了 form_widgets.js
,但我不明白如何正确覆盖Field。
I created form_widgets.js
in my module, but I not understand how properly override Field.
odoo.define('my_module.form_widgets', function (require) {
"use strict";
// what I should do here???
});
你能提供一些小例子吗?提前谢谢。
Can you provide small example? Thank in advance.
推荐答案
我找到了解决方案。
您需要做的第一件事是为前端创建静态。 JS:
The first thing you need to do it is create static for frontend. JS:
// path_to_your_module/static/src/js/form_widgets.js
odoo.define('your_module.form_widgets', function (require) {
"use strict";
var core = require('web.core');
var form_common = require('web.form_common');
var FieldChar = core.form_widget_registry.get('char');
FieldChar.include({
// this is will be work for all FieldChar in the system
template: 'MyChar', // my template for char fields
// we can create here any logic for render
//render_value: function() {
//}
});
// this is widget for unique CharField
var MyModuleFieldChar = FieldChar.extend({
template: 'MyUniqueChar' // my custom template for unique char field
});
// register unique widget, because Odoo does not know anything about it
core.form_widget_registry.add('my_unique_char', MyModuleFieldChar);
});
qWeb的模板:
<?xml version="1.0" encoding="UTF-8"?>
<templates xml:space="preserve">
<!-- path_to_your_module/static/src/xml/form_widgets.xml -->
<t t-name="MyChar">
<!-- for example I just added new <span> to all FieldChar -->
<span>my_val</span>
<!-- this is original content for CharField from path_to_odoo/addons/web/static/src/xml/base.xml -->
<span t-att-class="'oe_form_field '+widget.widget_class" t-att-style="widget.node.attrs.style">
<t t-if="!widget.get('effective_readonly')">
<input t-att-type="widget.password ? 'password' : 'text'"
t-att-barcode_events="widget.options.barcode_events"
t-att-id="widget.id_for_label"
t-att-tabindex="widget.node.attrs.tabindex"
t-att-autofocus="widget.node.attrs.autofocus"
t-att-placeholder="widget.node.attrs.placeholder"
t-att-maxlength="widget.field.size"
/><img class="oe_field_translate oe_input_icon" t-if="widget.field.translate" t-att-src='_s + "/web/static/src/img/icons/terp-translate.png"' width="16" height="16" border="0"/>
</t>
<t t-if="widget.get('effective_readonly')">
<span class="oe_form_char_content"></span>
</t>
</span>
</t>
<!-- This is example template for my unique field -->
<t t-name="MyUniqueChar">
<span>unique_char</span>
</t>
</templates>
第二步 - 包括我们的静态文件。
Second step - include our static files.
创建新视图,添加资产:
<?xml version="1.0" encoding="utf-8"?>
<!-- path_to_your_module/views/assets.xml -->
<openerp>
<data>
<template id="assets_backend" name="mail assets" inherit_id="web.assets_backend">
<xpath expr="." position="inside">
<script type="text/javascript" src="/your_module/static/src/js/form_widgets.js"></script>
</xpath>
</template>
</data>
</openerp>
在模块的 openerp .py 中添加下一部分:
In openerp.py of your module add next sections:
'data': [
'views/assets.xml',
# other files
],
'qweb': [
'static/src/xml/*.xml',
],
此后,我们的FieldChar将对系统中的所有 CHAR 字段起作用。如果我们需要使用 my_unique_char
,我们只需要将属性小部件添加到我们的字段中,就像这样:
After this will be work our FieldChar for all CHAR fields in the system. If we need to use my_unique_char
we need just add attribute widget to field of our from like this:
<field name="name" widget="my_unique_char"/>
