你好，odoo12 菜单显示不了，

[mylovetop]

<?xml version="1.0" ?>
<odoo>
    <record id="module_library_category" model="ir.module.category">
        <field name="name">Library</field>
    </record>
    <!-- Library User Group -->
    <record id="library_group_user" model="res.groups">
        <field name="name">User</field>
        <field name="category_id" ref="module_library_category" />
        <field name="implied_ids" eval="[(4, ref('base.group_user'))]" />
    </record>
    <!-- Library Manager Group -->
    <record id="library_group_manager" model="res.groups">
        <field name="name">Manager</field>
        <field name="category_id" ref="module_library_category" />
        <field name="implied_ids" eval="[(4, ref('base.group_user'))]" />
        <field name="users" eval="[
                    (4, ref('base.user_root')),
                    (4, ref('base.user_admin'))
                ]" />
    </record>
    <data noupdate="1">
        <record id="book_user_rule" model="ir.rule">
            <field name="name">Library Book User Access</field>
            <field name="model_id" ref="model_library_book" />
            <field name="domain_force">
                [('active','=',True)]
            </field>
            <field name="groups" eval="[(4,ref('library_group_user'))]" />
        </record>
    </data>
</odoo>

以上代码中，

<record id="library_group_manager" model="res.groups">
        <field name="name">Manager</field>
        <field name="category_id" ref="module_library_category" />
        <field name="implied_ids" eval="[(4, ref('base.group_user'))]" />
        <field name="users" eval="[
                    (4, ref('base.user_root')),
                    (4, ref('base.user_admin'))
                ]" />
    </record>

服务器代码启动一直报错，

raise ValidationError(_('The user cannot have more than one user types.'))
odoo.tools.convert.ParseError: "一个用户不能有多种用户类型
None" while parsing /Users/odoo-12.0/my-modules/library_app/security/library_security.xml:13, near
<record id="library_group_manager" model="res.groups">
        <field name="name">Manager</field>
        <field name="category_id" ref="module_library_category"/>
        <field name="implied_ids" eval="[(4, ref('base.group_user'))]"/>
        <field name="users" eval="[                     (4, ref('base.user_root')),                     (4, ref('base.user_admin'))                 ]"/>
    </record>

把users 代码注释掉， 能正常启动，但是新建的菜单无法显示，请教下 这个怎么解决？ 谢谢
