I created a model like this
class FoundCheque(models.TransientModel):
_name = "found.cheque"
date_Found = fields.Date(string='Found Date', default=fields.Date.context_today, required=True, translate=True)
and its view
<?xml version="1.0" encoding="UTF-8"?>
<odoo>
<data>
<record model="ir.ui.view" id="wizard_found_cheque">
<field name="name">found.cheque.wizard</field>
<field name="model">found.cheque</field>
<field name="arch" type="xml">
<form string="found Cheque">
<group>
<field name="date_found" style="width:40%%"/>
</group>
<footer>
<button name="found_cheque" string="Post" type="object" class="oe_highlight"/>
or <button string="Cancel" class="oe_link" special="cancel"/>
</footer>
</form>
</field>
</record>
</data>
</odoo>
but when I try to update the module after restarting the service it just says:
Field `date_found` does not exist
Error context:
View `found.cheque.wizard`
[view_id: 4100, xml_id: n/a, model: found.cheque, parent_id: n/a]
None" while parsing /opt/odoo/odoo11-custom-addons/cheque_management/views/found_cheque.xml:4, near
<record model="ir.ui.view" id="wizard_found_cheque">
<field name="name">found.cheque.wizard</field>
<field name="model">found.cheque</field>
<field name="arch" type="xml">
<form string="found Cheque">

or <button string="Cancel" class="oe_link" special="cancel"/>
</footer>
</form>
</field>
</record>and just to add I restarted the service several times
more information will be added on request
Your field name in python file is date_Found and date_found in xml. Both are different. so change field name in xml file
