Qweb，阻止报告
Qweb, Blocking the report
我需要在草稿状态下阻止报告，如果用户在草稿状态下单击打印按钮生成 pdf，它应该会发出警告消息。

一般情况下Qweb报表可以两种方式打印
- 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。
如果您将报告调用为 PDF，则调用 get_pdf() 方法，或者如果您调用报告输入 HTML 然后 get_html() 方法 被调用报告模块。
因此在我们的例子中，您必须在我们的模块中重写上述两个方法，然后添加类似这样的东西。
覆盖报表模块的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 get_html() 并检查它
听到代码将检查销售订单报告操作。
以上代码我这边可以测试成功。
希望这对您有所帮助..:)
