在 Odoo 8 中，您可以像下面一样修补 addons/report/controllers/main.py 的 report_download 方法（在 FIX START 和 END 之间）。然后，它将使用报表操作定义中附件属性的代码。由于系统始终会将文件作为附件保存在数据库中，因此您可以进一步更改行为，仅在attachment_use 设置为 True 时才保存在数据库中。这样就不需要添加额外的字段和更改视图。

"""This function is used by 'qwebactionmanager.js' in order to trigger the download of

requestcontent = simplejson.loads(data)
url, type = requestcontent[0], requestcontent[1]

您可以通过以下方式设置报告操作的附件属性：
<?xml version="1.0" encoding="UTF-8"?>
<openerp>
<data>
<!-- rename the file names of the standard rfq report -->
<record id="purchase.report_purchase_quotation" model="ir.actions.report.xml">
<field name="attachment">'RFQ_'+object.name+'.pdf'</field>
</record>
</data>
</openerp>
这是 addons/report/report.py 中 Report 对象的 _check_attachment 的补丁，用于修改 Attachment_use 行为：
@api.v7
def _check_attachment_use(self, cr, uid, ids, report):
""" Check attachment_use field. If set to true and an existing pdf is already saved, load
this one now. Else, mark save it.
"""
save_in_attachment = {}
save_in_attachment['model'] = report.model
save_in_attachment['loaded_documents'] = {}
if report.attachment:
for record_id in ids:
obj = self.pool[report.model].browse(cr, uid, record_id)
filename = eval(report.attachment, {'object': obj, 'time': time})
# If the user has checked 'Reload from Attachment'
if report.attachment_use:
alreadyindb = [('datas_fname', '=', filename),
('res_model', '=', report.model),
('res_id', '=', record_id)]
attach_ids = self.pool['ir.attachment'].search(cr, uid, alreadyindb)
if attach_ids:
# Add the loaded pdf in the loaded_documents list
pdf = self.pool['ir.attachment'].browse(cr, uid, attach_ids[0]).datas
pdf = base64.decodestring(pdf)
save_in_attachment['loaded_documents'][record_id] = pdf
_logger.info('The PDF document %s was loaded from the database' % filename)
continue # Do not save this document as we already ignore it
# FIX START (commenting out below lines and indenting the else clause one level down)
# If the user has checked 'Save as Attachment Prefix'
#~ if filename is False:
#~ # May be false if, for instance, the 'attachment' field contains a condition
#~ # preventing to save the file.
#~ continue
else:
save_in_attachment[record_id] = filename # Mark current document to be saved
# FIX END
return save_in_attachment
