(Odoo) 如何从网站下载 PDF 报告？

问题描述

如何从网站上的控制器下载 pdf 报告 (odoo v14)？

我尝试使用以下代码解决问题：

@http.route(['/my/projects/invoices/<int:invoice_id>/download'],type='http',auth="user",website=True)
def download_customer_project_report(self,invoice_id):

    invoice = request.env.ref('account.report_invoice_with_payments').sudo()._render_qweb_pdf([invoice_id])[0]
    pdf_http_headers = [('Content-Type','application/pdf'),('Content-Length',len(pdf))]

    return request.make_response(invoice,headers=pdf_http_headers)

但我一直遇到这个错误 AttributeError: 'ir.ui.view' object has no attribute '_render_qweb_pdf'。

谢谢

解决方法

似乎 [0] 在您的代码的第 4 行对我不利。你能不能把它去掉然后再试一次。例如：

@http.route(['/my/projects/invoices/<int:invoice_id>/download'],type='http',auth="user",website=True)
def download_customer_project_report(self,invoice_id):

    invoice = request.env.ref('account.report_invoice_with_payments').sudo()._render_qweb_pdf([invoice_id])
    pdf_http_headers = [('Content-Type','application/pdf'),('Content-Length',len(pdf))]

    return request.make_response(invoice,headers=pdf_http_headers)

,

我设法用以下代码解决了这个问题：

@http.route(['/my/projects/invoices/<int:invoice_id>/download'],website=True)
def download_pdf(self,invoice_id):
    invoice = request.env['account.move'].sudo().search([('id','=',invoice_id)],limit=1)
    if not invoice or invoice.partner_id.id != request.env.user.partner_id.id:
        return None
    pdf,_ = request.env['ir.actions.report']._get_report_from_name(
        'account.report_invoice').sudo()._render_qweb_pdf(
        [int(invoice_id)])
    pdf_http_headers = [('Content-Type',len(pdf)),('Content-Disposition',content_disposition('%s - Invoice.pdf' % (invoice.name)))]
    return request.make_response(pdf,headers=pdf_http_headers)

我没有使用 ref，而是使用了 _get_report_from_name 方法。
