形式2:弹出对话框效果

说明:打开estate.customer.wizard默认form视图

形式3:实现类似浏览器刷新当前页面效果

return {

为列表视图添加自定义上传数据文件按钮

odoo14\custom\estate\static\src\js\estate_customer_tree_upload.js

                if (record.id) {
                    filtered.push(record.id);
                }
                return filtered;
            }, []);
            // 请求模型方法

                model: 'estate.customer',  //模型名称
                method: 'create_customer_from_attachment', // 模型方法
                args: ["", attachent_ids],
                context: this.initialState.context,
            }).then(function(result) { // result为一个字典
                if (result.action_type == 'reload') {
                    self.trigger_up('reload'); // 实现在不刷新页面的情况下,刷新列表视图// 此处换成 self.reload(); 发现效果也是一样的
                } else if (result.action_type == 'do_action') {
                    self.do_action(result.action); // 执行action动作
                } else { // 啥也不做
                }
                // 重置 file input, 如果需要,可以再次选择相同的文件,如果不添加以下这行代码,不刷新当前页面的情况下,无法重复导入相同的文件

             }).catch(function () {                
                self.$('.o_estate_customer_upload .o_input_file').val('');
            });
        },
        _onUpload: function (event) {
            var self = this;
            // 如果隐藏的上传表单不存在则创建
            var $formContainer = this.$('.o_content').find('.o_estate_customer_upload');
            if (!$formContainer.length) {
                // estate.CustomerHiddenUploadForm定义在对应的QWeb模版中
                $formContainer = $(qweb.render('estate.CustomerHiddenUploadForm', {widget: this}));
                $formContainer.appendTo(this.$('.o_content'));
            }
            // 触发input选取文件
            this.$('.o_estate_customer_upload .o_input_file').click();
        },
    }
    return UploadAttachmentMixin;
});
odoo.define('estate.customer.tree', function (require) {
"use strict";
    var core = require('web.core');
    var ListController = require('web.ListController');
    var ListView = require('web.ListView');
    var UploadAttachmentMixin = require('estate.upload.customer.mixin');
    var viewRegistry = require('web.view_registry');
    var CustomListController = ListController.extend(UploadAttachmentMixin, {
        buttons_template: 'EstateCustomerListView.buttons',
        events: _.extend({}, ListController.prototype.events, {
            'click .o_button_upload_estate_customer': '_onUpload',
            'change .o_estate_customer_upload .o_form_binary_form': '_onAddAttachment',
        }),
    });
    var CustomListView = ListView.extend({
        config: _.extend({}, ListView.prototype.config, {
            Controller: CustomListController,
        }),
    });
    viewRegistry.add('estate_customer_tree', CustomListView);
});

说明:如果其它模块的列表视图也需要实现类似功能,想复用上述js,需要替换js中以下内容:

加载js脚本xml文件定义

odoo14\custom\estate\views\webclient_templates.xml

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <template id="assets_common" inherit_id="web.assets_common" name="Backend Assets (used in backend interface)">

        </xpath>
    </template>
</odoo>

按钮视图模板定义

odoo14\custom\estate\static\src\xml\estate_customer_tree_view_buttons.xml

<?xml version="1.0" encoding="UTF-8"?>
<templates>
    <t t-name="estate.CustomerHiddenUploadForm">
        <div class="d-none o_estate_customer_upload">
            <t t-call="HiddenInputFile">
                <t t-set="multi_upload" t-value="true"/>
                <t t-set="fileupload_id" t-value="widget.fileUploadID"/>
                <t t-set="fileupload_action" t-translation="off">/web/binary/upload_attachment</t>
                <input type="hidden" name="model" value=""/>
                <input type="hidden" name="id" value="0"/>
            </t>
        </div>
    </t>
    <t t-name="EstateCustomerListView.buttons" t-extend="ListView.buttons">
        <t t-jquery="button.o_list_button_add" t-operation="after">
            <!--btn表示按钮类
              按钮颜色:btn-primary--主要按钮,btn-secondary次要按钮
              按钮大小:btn-sm小按钮,btn-lg大按钮
              默认按钮:btn-default-->
            <button type="button" class="btn btn-primary o_button_upload_estate_customer">Upload</button>
        </t>
    </t>
</templates>

说明:

t-name:定义模版名称

t-extend:定义需要继承的模板。

t-jquery:接收一个CSS 选择器,用于查找上下文中,同CSS选择器匹配的元素节点(为了方便描述,暂且称之为上下文节点)

t-operation:设置需要对上下文节点执行的操作(为了方便描述,暂且将t-operation属性所在元素称为模板元素),可选值如下:

注意:参考官方文档,t-extend这种继承方式为旧的继承方式,已废弃,笔者实践了最新继承方式,如下

<?xml version="1.0" encoding="UTF-8"?>
<templates>
    <t t-name="DataImportTestingListView.buttons" t-inherit="ListView.buttons" t-inherit-mode="primary">
        <xpath expr="//button[@calss='btn btn-primary o_list_button_add']" position="after">
            <button type="button" class="btn btn-primary o_button_upload_estate_customer">Upload</button>
        </xpath>
    </t>
</templates>

发现会报错:

ValueError: Module ListView not loaded or inexistent, or templates of addon being loaded (estate) are misordered

模型访问权限配置

最终效果

odoo 给列表视图添加按钮实现数据文件导入
