python之如何更改打印的 qweb 文件名

如何根据源文档字段名更改打印的qweb文件名？ 我在模型 stock.picking 中

因此，当我单击打印 -> 交货单时，将打印 qweb，但文件名将取决于源文档字段。 在这里，我展示了解释我的意思的图片。

EXAMPLE

请您参考如下方法:

您可以使用配置给动态报​​告名称，但它会在您打印一份报告时应用。

下面是在报告中打印自定义名称的例子。在ir.actions.report.xml中创建一个字段，其中用户可以配置报告名称。

from openerp import models, fields 
class IrActionsReportXml(models.Model): 
    _inherit = 'ir.actions.report.xml' 
 
    download_filename = fields.Char( 
        'Download filename') 

现在您需要创建两个文件。

1. 报告控制者

   from openerp import http 
   from openerp.addons.mail.models import mail_template 
   from openerp.addons.report.controllers.main import ReportController 
   from openerp.addons.web.controllers.main import content_disposition 
    
    
   class ReportController(ReportController): 
       @http.route([ 
           '/report/<path:converter>/<reportname>', 
           '/report/<path:converter>/<reportname>/<docids>', 
       ]) 
       def report_routes(self, reportname, docids=None, converter=None, **data): 
           response = super(ReportController, self).report_routes( 
               reportname, docids=docids, converter=converter, **data) 
           if docids: 
               docids = [int(i) for i in docids.split(',')] 
           report_xml = http.request.session.model('ir.actions.report.xml') 
           report_ids = report_xml.search( 
               [('report_name', '=', reportname)]) 
           for report in report_xml.browse(report_ids): 
               if not report.download_filename: 
                   continue 
               objects = http.request.session.model(report.model)\ 
                   .browse(docids or []) 
               generated_filename = mail_template.mako_template_env\ 
                   .from_string(report.download_filename)\ 
                   .render({ 
                       'objects': objects, 
                       'o': objects[:1], 
                       'object': objects[:1], 
                       'ext': report.report_type.replace('qweb-', ''), 
                   }) 
               response.headers['Content-Disposition'] = content_disposition( 
                   generated_filename) 
           return response 
    
       @http.route(['/report/download']) 
       def report_download(self, data, token): 
           response = super(ReportController, self).report_download(data, token) 
           # if we got another content disposition before, ditch the one added 
           # by super() 
           last_index = None 
           for i in range(len(response.headers) - 1, -1, -1): 
               if response.headers[i][0] == 'Content-Disposition': 
                   if last_index: 
                       response.headers.pop(last_index) 
                   last_index = i 
           return response 
   

2.报表.py

    import json 
    from openerp import http 
    from openerp.addons.web.controllers import main 
    from openerp.addons.mail.models import mail_template 
 
 
    class Reports(main.Reports): 
        @http.route('/web/report', type='http', auth="user") 
        @main.serialize_exception 
        def index(self, action, token): 
            result = super(Reports, self).index(action, token) 
            action = json.loads(action) 
            context = dict(http.request.context) 
            context.update(action["context"]) 
            report_xml = http.request.env['ir.actions.report.xml'] 
            reports = report_xml.search([ 
                ('report_name', '=', action['report_name']), 
                ('download_filename', '!=', False)]) 
            for report in reports: 
                objects = http.request.session.model(context['active_model'])\ 
                    .browse(context['active_ids']) 
                generated_filename = mail_template.mako_template_env\ 
                    .from_string(report.download_filename)\ 
                    .render({ 
                        'objects': objects, 
                        'o': objects[0], 
                        'object': objects[0], 
                    }) 
                result.headers['Content-Disposition'] = main.content_disposition( 
                    generated_filename) 
            return result 

Odoo 社区为我们提供了报告自定义名称的默认模块。您可以直接安装此模块并设置报告名称，如:${o.name}

这里的o代表你的记录。
