Public bug reported:
When I use datatable in a tabletab, I use filter_type = "server" and
filter_choices = (('hostname', _("host name"), True),). Then I can't get the
data from table. However, it is just OK in datatable directly in view.
I read about source code and write my filter function as below:
def get_filters(self, filters):
filter_action = self._tables.items()[0][1]._meta._filter_action
if filter_action:
filter_field = self._tables.items()[0][1].get_filter_field()
if filter_action.is_api_filter(filter_field):
filter_string = self._tables.items()[0][1].get_filter_string()
if filter_field and filter_string:
filters[filter_field] = filter_string
return filters
I print the self._tables.items()[0][1] and it is the table instance I need. I
print self._tables.items()[0][1].get_filter_field() but it is null. Then I read
the source code and find the function is like this:
def get_filter_field(self):
"""Get the filter field value used for 'server' type filters. This
is the value from the filter action's list of filter choices.
"""
filter_action = self._meta._filter_action
param_name = '%s_field' % filter_action.get_param_name()
filter_field = self.request.session.get(param_name, '')
return filter_field
I print param_name and it is the field from the website. Then I know
filter_field is get from the session according to the code note. I print the
session(with __dict__) but it doesn't have a field called '*__q_field'(* is
short for my table name), so I wonder if the parameters are stored in session
as the code note said.
Can anyone give me any advice?
