Hi,

If your report is linked directly with a record, like for example sale order print, you can access it as follows:

http://your_domain_or_ip/report/pdf/sale.report_saleorder/38  where 38 is the ID of the sale.order

Reports are web pages

Reports are dynamically generated by the report module and can be accessed directly via URL:

For example, you can access a Sale Order report in html mode by going to http://your_domain_or_ip/report/html/sale.report_saleorder/38

Or you can access the pdf version at http:///report/pdf/sale.report_saleorder/38

Thanks

Hi,
Refer to this code

pdf = request.env.ref('account.account_invoices').sudo().render_qweb_pdf([res.id])[0]
base_url = request.env['ir.config_parameter'].sudo().get_param('web.base.url')
attachment = request.env['ir.attachment'].sudo().create({
'name': res.name + ".pdf",
'type': 'binary',
'res_id': res.id,
'res_model': 'account.move',
'datas': base64.b64encode(pdf),
'mimetype': 'application/x-pdf'
})
url = '%s/web/invoice.pdf?model=ir.attachment&id=%s&name=inv.pdf&field=datas' % (
base_url, attachment.id
)

class BinaryAttachment(http.Controller):
""" taking url of attachment from ir.attachment"""

if status in [301, 304] or (status != 200 and download):
return request.env['ir.http']._response_by_status(status, headers,

response.status_code = status
return response

Hope it helps
