Hi, 

I am trying to show odoo 14 rpeort in HTML field. I was using following code for showing report in odoo 10:

 @api.multi

 def generate_preview(self,id):

data = self.id

html = self.env['report'].get_html(self, 'sale_order_form_report.report_form_view',data=data)

self.write({'report': html})

return True

Noe its not working in odoo 14 due to following function:

AttributeError: 'ir.actions.report' object has no attribute 'get_html'

I have used help from the following \this link . But still showing following error

AttributeError: 'ir.actions.report' object has no attribute 'render_qweb_html'

Now what will be the best/optimal way to show a qweb report in html field in odoo 14.
