How to apply multiple filters to a group by query

[vikramsinghchandel]

How can i apply multiple filters to a group by query following does not work
filters = (pydruid.utils.filters.Dimension("unit")=='000721') & (pydruid.utils.filters.Dimension("val") > 0)
query1 = query.groupby(
datasource=dataSource,
granularity='minute',
#intervals='2016-08-01/p12w',
#intervals='2016-08-01/pt24h',
intervals='2016-08-11/2016-08-15',
dimensions=["GPN"],
filter=filters,
aggregations={"val_sum": ag.doublesum("val"),"val_count": ag.count("val")},
post_aggregations={"Avg": (pag.Field("val_sum") / pag.Field("val_count"))},
context={"timeout": 600000}#,
# limit_spec={
#"type": "default",
# "limit": 50,
# "columns" : ["sensor_val_sum","sensor_val_count"]
# }
)

Gives following error
Traceback (most recent call last):

Import the Filter class

from pydruid.utils.filters import Filter
filter_unit_obj = Filter(dimension='unit', value='000721')

val > 0, these kind work can be handled by make use of javascript functionality

filter_val_obj = Filter(
                    type= 'javascript',
                    dimension= 'val',
                    function= "function(x){ return x > 0}"
                )

Now join them like which can be substitue to the query.groupby function.

query_filter_obj = Filter(
                     type= 'and',
                     fields= [ filter_unit_obj, filter_val_obj]
                    )

Hope they can add this into filter documentation. Really helpful
