Thank you so much. Here, whenever I try to select a product from add line that I made previously, another short page pop up. But I want to select products inside line just like order_line . What I need to do here?
here my code:
.py:
from odoo import models, fields, api

class CrmLead(models.Model):
_inherit = 'crm.lead'

product_ids = fields.Many2many('product.product', string='Products', edit="inline")
combined_info = fields.Char(string='Product Info', compute='_compute_combined_info')
def _compute_combined_info(self):
for product in self:
product.combined_info = f"{product.default_code} - {product.name}"
from odoo import models, fields, api

class ProductImage(models.Model):
_inherit = 'product.product'
_description = 'Product Image'

product_image = fields.Binary(string='Design')
combined_info = fields.Char(string='Product Info', compute='_compute_combined_info')

def _compute_combined_info(self):
for product in self:
product.combined_info = f"{product.default_code} - {product.name}"

.xml:
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<record id="wise_crm_lead_view_form_inherit" model="ir.ui.view">
<field name="name">techtrioz.crm.lead.form.inherit</field>
<field name="model">crm.lead</field>
<field name="inherit_id" ref="crm.crm_lead_view_form"/>
<field name="arch" type="xml">
<xpath expr="//page[@name='internal_notes']" position='after'>
<page string="Product Info" name="product_info">
<tree position="inside" editable="bottom">
<field name="product_ids" widget="one2many_list">
<tree>
<!-- <field name="default_code" string="Products"/> -->
<field name="combined_info" string="Product Info"/>
<field name="product_image" widget="image" options='{"size": [80, 80]}'/>
</tree>
</field>
</tree>
</page>
</xpath>
</field>
</record>
</odoo>

It worked. Thank you
