I've created a custom widget in Odoo, and display it for a form field. My template looks like this:

After spending a day digging in the source code, I've found the solution! It doesn't really involve the template, but I got the idea from the source code of default text field widget, so I think it shouldn't be considered as "hacking".

花了一天时间挖掘源代码后，我找到了解决方案！它并不真正涉及模板，但我从默认文本字段小部件的源代码中得到了这个想法，所以我认为它不应该被视为“黑客”。

Here's my custom widget class:

这是我的自定义窗口小部件类：

openerp.mymodule = function(instance, local) {
    instance.ImageDisplayer = instance.web.form.AbstractField.extend({
        template: "ImageDisplayer",
        init: function (view, code) {
            this._super(view, code);
        },
        // The key part:
        render_value: function() {
            this.$el[0].src = this.get("value");
        }
    });
    instance.web.form.widgets.add('ImageDisplayer', 'instance.ImageDisplayer');
}

My template now does not contain anything special:

我的模板现在不包含任何特殊内容：

<?xml version="1.0" encoding="UTF-8"?>
<templates xml:space="preserve">
    <t t-name="ImageDisplayer">
        <img />
    </t>
</templates>

Works like a charm. It even updates the page whenever I do a change on server-side.

奇迹般有效。每当我在服务器端进行更改时，它甚至会更新页面。

Odoo documentation should really be more talkative!!!

Odoo文档真的应该更健谈！

Update: the answer applies to Odoo 8. It may work slightly differently in Odoo 9, because they've revised the UI framework in the new version.

更新：答案适用于Odoo 8.它在Odoo 9中可能略有不同，因为他们在新版本中修改了UI框架。

We can do like that

我们可以这样做

<img t-att-src="kanban_image('model.name', 'image_small', record.id.value)"/>

Where

哪里

model.name is table name,

model.name是表名，

image_small is a field name which will hold/store binary type of data.

image_small是一个字段名称，用于保存/存储二进制数据类型。

EDIT:

编辑：

To display value of field in template, you may try with this

要在模板中显示字段的值，您可以尝试使用它

<img t-att-src="record.field_name"/>
