Odoo Custom Report - External ID not found

Question

I am creating a custom report in Inventory (stock) module for which I have created a pop up view (window) for selection then after clicking a submit button, a python function is called. The problem is I am getting an internal server error stating

Value Error: External ID not found in the system: stock.customer_detail_report

Here is stock_report_views.xml file:

<odoo>
<data>
<report
            string="Customer Report"
            id="action_customer_detail_report"
            model="customer.detail"
            name="stock.customer_detail_report"
            file="stock.customer_detail_report"
            report_type="qweb-pdf"
            print_report_name="Customer_Detail"
        />
    </data>
</odoo>

Here is the model customer_detail.py

class CustomerDetail(models.TransientModel):
    _name = 'customer.detail'
    _description = 'Customer Detail'    

    customer_vendor = fields.Many2one('res.partner', 
                        string="Customer/Vendor", help="List of Customer and Vendors")
    PO = fields.Integer('purchase.order', related="id")
    
    def open_table(self):
        self.ensure_one()
        return self.env.ref('action_customer_detail_report').report_action(self)

Here is the pop up view (window) customer_detail.xml:

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record id="view_customer_detail" model="ir.ui.view">
        <field name="name">Customer Details</field>
        <field name="model">customer.detail</field>
        <field name="arch" type="xml">
            <form string="Choose your date">
                <group>
                    <group>
                        <field name="customer_vendor" />
                    </group>
                </group>
                <footer>
                    <button name="open_table" string="Retrieve the Customer Details" type="object" class="btn-primary"/>
                    <button string="Cancel" class="btn-secondary" special="cancel" />
                </footer>
            </form>
        </field>
    </record>
    <record id="action_customer_detail" model="ir.actions.act_window">
        <field name="name">Customer Detail</field>
        <field name="res_model">customer.detail</field>
        <field name="view_type">form</field>
        <field name="view_mode">form</field>
        <field name="view_id" ref="view_customer_detail"/>
        <field name="target">new</field>
    </record>
    <menuitem id="menu_customer_detail" name="Customer Detail" parent="stock.menu_warehouse_report" sequence="100" action="action_customer_detail_report"/>
</odoo>

And here is the final view customer_detail_report.xml:

<?xml version="1.0" encoding="utf-8" ?>
<odoo>
    <template id="action_customer_detail_report">

            <t t-call="web.basic_layout">
              <div class="page" style="padding-top:-10%;">
                   <div class="col-xs-4" style="padding:1;">
                      <h1>This is a test</h1>
                   </div>
              </div>
            </t>
    </template>
</odoo>

Any idea why am I not able to link the report and not getting the popup window and final report view?

Answer 1

Looks like you are directly adding customization in stock module. I suggest you to make a custom module for proper implementation.

However, listing error I found in above code

1. customer_detail_report.xml Not defined in manifest file.

2. Template id in customer_detail_report.xml is wrong.

       <template id="customer_detail_report">
           <t t-call="web.basic_layout">
                 <div class="page" style="padding-top:-10%;">
                      <div class="col-xs-4" style="padding:1;">
                         <h1>This is a test</h1>
                      </div>
                 </div>
               </t>
       </template>
