实时服务器上的未知错误，但该模块在本地主机上运行良好

Question

i am currently working on a project built using python and xml on odoo framework to generate a custom qwebreport with some data. .Its working very well on localhost where the port is being generated very well without any issues. But when the module is run on a live server,it returns an error.The error is as follows:

Error:Odoo Server Error

Answer 1

have you used this:-

<record id="project_task_template" model="ir.actions.report">
        <field name="name">Project Report</field>
        <field name="model">project.task</field>
        <field name="report_type">qweb-pdf</field>
        <field name="report_name">construction_management.task_invoice</field>
        <field name="report_file">construction_management.task_invoice</field>
        <field name="binding_model_id" ref="model_project_task"/>
        <field name="binding_type">report</field>
    </record>

if so then please itrate docs over a for loop in your XML file: after this (t-call="web.basic_layout") like (t-foreach="docs" t-as='o') and use (o.field_name) for example:

<t t-foreach="doc.move_ids_without_package" t-as="line">
    <p t-out="line.product_uom_qty"/>
    <p t-out="line.display_name"/>
    <p t-out="line.product_id.name"/>
    
    <t t-if="website_label_type == 'bsku'">
        <span t-out="line.product_id.bsku"/>
    </t>
    <t t-else="">
        <span t-out="line.product_id.asin"/>
    </t>
</t>
