I am trying to install a module in odoo 12 that contains a view with ir.cron module type. but it shows me this error:
I do not know how to rectify it. Can anyone help me, please?
odoo.tools.convert.ParseError: "ERREUR: une valeur NULL viole la contrainte NOT NULL de la colonne « model_id »

<record model="ir.cron" id="deactivate_partner_discount_cron">
<field name="name">Annuler la remise mensuelle du client</field>
<field name="interval_number">1</field>
<field name="interval_type">months</field>

<field eval="False" name="doall"/>
<field eval="'res.partner'" name="model"/>
<field eval="'deactivate_partner_discount'" name="function"/>
<field eval="'()'" name="args"/>
</record>
The issue is with the line <field eval="'res.partner'" name="model"/>, the actual field name is model_id. you have to set the field as following
<field name="model_id" ref="model_res_partner"/>
As model_id is a Many2one relation with ir.model you can use ref with model xml id, for res.partner model xml id is model_res_partner.
