Question

我需要在草稿状态下阻止报告，在草稿状态下，如果用户单击打印按钮生成pdf，则应该发出警告消息。

提前致谢

一般案例Qweb报告可以双向打印

HTML
PDF

每次根据报告类型调用报告时，都会听到不同的报告方法正在调用。

如果您将报告称为 PDF ，则会调用 get_pdf（）方法，或者如果您将报告类型称为 HTML ，则<报告模块调用strong> get_html（）方法。

所以在我们的例子中你必须在我们的模块中覆盖上面两个方法然后添加这样的东西。

覆盖报告模块的get_pdf（）方法：

class Report(osv.Model):
    _inherit = "report"
    _description = "Report"

@api.v7
def get_pdf(self, cr, uid, ids, report_name, html=None, data=None, context=None):
    """This method generates and returns pdf version of a report.
    """
    order_pool=self.pool.get('sale.order')
    for order in order_pool.browse(cr, uid, ids, context=None):
        if order.state:
            if order.state == 'draft':
                raise osv.except_osv(_("Warning!"), _("Your Printed Report is in Draft State ...!! "))

    if context is None:
        context = {}

    if html is None:
        html = self.get_html(cr, uid, ids, report_name, data=data, context=context)

    html = html.decode('utf-8')  # Ensure the current document is utf-8 encoded.

    # Get the ir.actions.report.xml record we are working on.

    report = self._get_report_from_name(cr, uid, report_name)
    # Check if we have to save the report or if we have to get one from the db.
    save_in_attachment = self._check_attachment_use(cr, uid, ids, report)
    # Get the paperformat associated to the report, otherwise fallback on the company one.
    if not report.paperformat_id:
        user = self.pool['res.users'].browse(cr, uid, uid)
        paperformat = user.company_id.paperformat_id
    else:
        paperformat = report.paperformat_id

    # Preparing the minimal html pages
    css = ''  # Will contain local css
    headerhtml = []
    contenthtml = []
    footerhtml = []
    irconfig_obj = self.pool['ir.config_parameter']
    base_url = irconfig_obj.get_param(cr, SUPERUSER_ID, 'report.url') or irconfig_obj.get_param(cr, SUPERUSER_ID, 'web.base.url')

    # Minimal page renderer
    view_obj = self.pool['ir.ui.view']
    render_minimal = partial(view_obj.render, cr, uid, 'report.minimal_layout', context=context)

    # The received html report must be simplified. We convert it in a xml tree
    # in order to extract headers, bodies and footers.
    try:
        root = lxml.html.fromstring(html)
        match_klass = "//div[contains(concat(' ', normalize-space(@class), ' '), ' {} ')]"

        for node in root.xpath("//html/head/style"):
            css += node.text

        for node in root.xpath(match_klass.format('header')):
            body = lxml.html.tostring(node)
            header = render_minimal(dict(css=css, subst=True, body=body, base_url=base_url))
            headerhtml.append(header)

        for node in root.xpath(match_klass.format('footer')):
            body = lxml.html.tostring(node)
            footer = render_minimal(dict(css=css, subst=True, body=body, base_url=base_url))
            footerhtml.append(footer)

        for node in root.xpath(match_klass.format('page')):
            # Previously, we marked some reports to be saved in attachment via their ids, so we
            # must set a relation between report ids and report's content. We use the QWeb
            # branding in order to do so: searching after a node having a data-oe-model
            # attribute with the value of the current report model and read its oe-id attribute
            if ids and len(ids) == 1:
                reportid = ids[0]
            else:
                oemodelnode = node.find(".//*[@data-oe-model='%s']" % report.model)
                if oemodelnode is not None:
                    reportid = oemodelnode.get('data-oe-id')
                    if reportid:
                        reportid = int(reportid)
                else:
                    reportid = False

            # Extract the body
            body = lxml.html.tostring(node)
            reportcontent = render_minimal(dict(css=css, subst=False, body=body, base_url=base_url))

            contenthtml.append(tuple([reportid, reportcontent]))

    except lxml.etree.XMLSyntaxError:
        contenthtml = []
        contenthtml.append(html)
        save_in_attachment = {}  # Don't save this potentially malformed document

    # Get paperformat arguments set in the root html tag. They are prioritized over
    # paperformat-record arguments.
    specific_paperformat_args = {}
    for attribute in root.items():
        if attribute[0].startswith('data-report-'):
            specific_paperformat_args[attribute[0]] = attribute[1]

    # Run wkhtmltopdf process
    return self._run_wkhtmltopdf(
        cr, uid, headerhtml, footerhtml, contenthtml, context.get('landscape'),
        paperformat, specific_paperformat_args, save_in_attachment
    )

与方法相同，您可以在模块中覆盖为get_html（）并进行检查

听到代码将检查销售订单报告操作。

以上代码可以从我这边成功测试。

我希望这对你有用..：）
