Migrate base odoo12

Question

I want to migrate the database from one computer to another. I downloaded the backup and transferred all installed modules to this computer. But when I enter the database, I get an error:

raise QWebException("Error to render compiling AST", e, path, node and etree.tostring(node[0], encoding='unicode'), name) odoo.addons.base.models.qweb.QWebException: 'res.users' object has no attribute 'sidebar_type' Traceback (most recent call last): File "c:\program files (x86)\odoo 12.0\server\odoo\addons\base\models\qweb.py", line 346, in compiled_fn return compiled(self, append, new, options, log) File "", line 1, in template_178_234 File "", line 2, in body_call_content_233 AttributeError: 'res.users' object has no attribute 'sidebar_type' Error to render compiling AST AttributeError: 'res.users' object has no attribute 'sidebar_type' Template: 178 Path: /templates/t/t/t[4] Node:< t t-set="body_classname" t-value="'o_web_client mk_sidebar_type' + request.env.user.sidebar_type or 'large'"/> - - -

I looked at this place. This muk_web_theme module:

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    
    <template id="webclient_bootstrap" name="Web Client" inherit_id="web.webclient_bootstrap">
        <xpath expr="//t[@t-set='body_classname']" position="after">
            <t t-set="body_classname" t-value="'o_web_client mk_sidebar_type_' + request.env.user.sidebar_type or 'large'"/>
        </xpath>
        <xpath expr="//*[hasclass('o_main')]" position="attributes">
            <attribute name="t-attf-class">o_main mk_chatter_position_#{request.env.user.chatter_position or 'normal'}</attribute>
        </xpath>
    </template>
    
</odoo>

        init_res = super(ResUsers, self).__init__(pool, cr)
        type(self).SELF_WRITEABLE_FIELDS = list(self.SELF_WRITEABLE_FIELDS)
        type(self).SELF_WRITEABLE_FIELDS.extend(['sidebar_type'])
        type(self).SELF_WRITEABLE_FIELDS.extend(['chatter_position'])
        type(self).SELF_READABLE_FIELDS = list(self.SELF_READABLE_FIELDS)
        type(self).SELF_READABLE_FIELDS.extend(['sidebar_type'])
        type(self).SELF_READABLE_FIELDS.extend(['chatter_position'])
        return init_res

What could be the problem?

Check if modules are visible to odoo. Module versions should stay the same when you are migrating.

Try with empty base and see if there are any errors after initializing your database.

Try to install your modules to empty base.
