using censusdata.variable_info.censustable with full subject tables #32

Closed josephholler closed 3 years ago

josephholler commented 3 years ago

I am attempting to search for variable information on an ACS 5-year subject table with this code:

censusdata.variable_info.censustable('acs5',2018,'S1810')

which I thought should work, since you can use the census API to query this group in full: https://api.census.gov/data/2018/acs/acs5/subject?get=group(S1810)&for=county:*

I found that adding sub-table information will work, e.g.

censusdata.variable_info.censustable('acs5',2018,'S1810_C01')

Meanwhile, a similar API Query does not work: https://api.census.gov/data/2018/acs/acs5/subject?get=group(S1810_C01)&for=county:*

I wonder if a new feature could use the first query to find all the S1810 variables?

Hiya - my simple PR should address this.

Just for some background, the censusdata.variable_info.censustable() function does not make a Census API call, but instead looks through this package's variables/*.json files. I'm under the impression that these are mirrored copies of the API output to reduce API calls.

That is correct, censustable() does not rely on an API call. The requested feature is added in version 1.15. Thank you for the suggestion.
