I tried to apply process_template() to iframe viz.
I'm trying to call another chart with parameters in json data in url, for
example
%22select_country%22%3A%22{{url_param('cartina',default='Toscana_province_2020')}}%22
in place of original
%22select_country%22%3A%22Toscana_province_2020%22
I tried to edit get_data() in this way:
class IFrameViz(BaseViz):
"""You can squeeze just about anything in this iFrame component"""
viz_type = "iframe"
verbose_name = _("iFrame")
credits = 'a <a href="https://github.com/airbnb/superset";>Superset</a>
original'
is_timeseries = False
def query_obj(self):
return None
def get_df(self, query_obj: Optional[Dict[str, Any]] = None) ->
pd.DataFrame:
return pd.DataFrame()
def get_data(self, df: pd.DataFrame) -> VizData:
template_processor = get_template_processor(self.datasource.database)
self.form_data['url']=template_processor.process_template(self.form_data['url'])
return {"iframe": True }
If I look at json I see "url" field with parameters replaced by correct
values, but url called by browser in order to fill page has parameters replaced
by anything.
example: in iframe URL I put ....&height={{url_param('altezza',default=300)}}
in json of chart I see ...&height=300
but page has been called with ...&height=
Can anyone help me ?
