JsonObject.read_from_file error?

karthikraman commented 5 years ago

Perhaps because of some wrong version?

I'm basically trying to read a pre-written json file and dump it with floating_point_precision=4:

TEST_DATA_PATH = os.path.join(os.path.dirname(__file__), 'spatio_temporal/data')
ORIG_DATA_PATH = os.path.expanduser('~/Documents')
for fname in sys.argv[1:]:
    panchangam_actual = JsonObject.read_from_file(filename=os.path.join(ORIG_DATA_PATH, fname))
    panchangam_actual.dump_to_file(filename=os.path.join(TEST_DATA_PATH, fname), floating_point_precision=4)

How did you generate this file you're reading? Can you attach it here? A generally safe way to create a file is to dump a python object.

karthikraman commented 5 years ago

The file was generated using get_panchangam Chennai-2019.json.gz

annual.py
1551:                 panchangam.dump_to_file(filename=fname)

This should have worked, right?

vvasuki commented 5 years ago

I think I got it.

The line 1525 in panchAngam should run in order for the reading to work.

common.update_json_class_index(sys.modules[__name__])

Which is why the reading happens properly in test_annual.py (which I updated and ran with your file) - it does:

from jyotisha.panchangam.spatio_temporal import City, annual

which runs the aforementioned line. .

jyotisham / jyotisha
