我正在扩展 Horizon 以包含一个自定义应用程序。在那个应用程序中,我有一个 DataTable:
class WorkloadsTable(tables.DataTable):
name = tables.Column("name", verbose_name=_("Name"))
description = tables.Column("description", verbose_name=_("Description"))
image = tables.Column("image", verbose_name=_("Image"))
flavor = tables.Column("flavor", verbose_name=_("Flavor"))
class Meta:
name = "workloads_table"
verbose_name = _("Workloads Table")
table_actions = (CreateNewWorkload, DeleteWorkload)
row_actions = (UpdateWorkload, DeleteWorkload)
它有一个 LinkAction:
class UpdateWorkload(tables.LinkAction):
name = "update"
verbose_name = _("Edit Workload")
url = "horizon:mydashboard:workloads_panel:update"
classes = ("ajax-modal",)
icon = "pencil"
def get_link_url(self, datum):
base_url = super(UpdateWorkload, self).get_link_url(datum)
workload_id = self.table.get_object_id(datum)
reversed = urlresolvers.reverse(self.url, args=[workload_id])
print reversed
return urlresolvers.reverse(self.url, args=[workload_id])
这个 LinkAction 指向我的 urls.py 中的一个路径:
WORKLOADS = r'(?P<workload_id>[^/]+)/%s$'
urlpatterns = patterns('',
url(r'^create/$', views.CreateView.as_view(), name='create'),
url(WORKLOADS % 'update', views.UpdateView.as_view(), name='update'),
url(r'^$', views.IndexView.as_view(), name='index'),
)
问题是:当我输入以下网址时:
http://localhost:9000/mydashboard/workloads_panel/3/update
I get: NoReverseMatch: Reverse for 'update' with arguments '()' and keyword arguments '{}' not found. 1 pattern(s) tried: [u'mydashboard/workloads_panel/(?P<workload_id>[^/]+)/update$']
我哪里错了?
