Hi,

I'm very new to Odoo development. Following with the example (https://books.google.ca/books?id=_fKBDwAAQBAJ&pg=PA119&lpg=PA119&dq=odoo+development+library.member&source=bl&ots=0sppGuWsVl&sig=ACfU3U3cQcwvQS8dfmxKTSEIeWx6MV_A-w&hl=en&sa=X&ved=2ahUKEwj54u2n8dnpAhUAj3IEHfKcDU8Q6AEwAHoECAoQAQ#v=onepage&q=odoo development library.member&f=false), I'm trying to create my first App. But after setting up security configuration, I can't access the Library menu from a portal register user(New register user from login page). However, Admin has no problem, I might be confused by Odoo's user group structure. not sure what is the correct way to grant access permission to a normal user. My security configuration is following:

ir.model.access.csv:

    id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

    access_book_user,BookUser,model_library_book,library_group_user,1,0,0,0

    access_book_manager,BookManager,model_library_book,library_group_manager,1,1,1,1

library_security.xml

    <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>

    <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('library_group_user'))]" />

        <field name="users" eval="[

                    (4, ref('base.user_root')),

                    (4, ref('base.user_admin'))

                ]" />

    </record>

I'm hoping the Library application could be open to all users by default. Be appreciated if anyone can explain with me the right approaching to the permission management. 

Thanks.
