许多字段的图像缩略图未显示

Question

我有一个多个图像字段，我正在使用多个二进制小部件。当我上传图像时，它不会显示图像缩略图

XML代码：

<record id="variant_image_upload_form" model="ir.ui.view">
        <field name="name">variant.image.upload.form</field>
        <field name="model">variant.image.upload</field>
        <field name="arch" type="xml">
            <form string="Images">
                <group>
                <field name="product_code" readonly="1"></field>
                <field name="color"></field>
                </group>
                <group>
                <field name="images" widget="many2many_binary" string="attach"></field>
                </group>

            </form>
        </field>
    </record>

白痴

images = fields.Many2many('ir.attachment', string="Image")
