OpenHEXA Toolbox DHIS2
The openhexa.toolbox.dhis2 library connects to a DHIS2 instance with metadata caching, queries org units, data elements and indicators, fetches dataValueSets and analytics, and handles ISO periods and pyramid enrichment.
Installation¶
Usage¶
Connect to an instance¶
Credentials are required to initialize a connection to a DHIS2 instance, and must be provided through a Connection object.
In an OpenHEXA workspace (e.g. in an OpenHEXA pipeline or in an OpenHEXA notebook), a Connection object can be created using the OpenHEXA SDK by providing the identifier of the workspace connection.
>>> from openhexa.sdk import workspace
>>> from openhexa.toolbox.dhis2 import DHIS2
>>> # initialize a new connection in an OpenHEXA workspace
>>> con = workspace.dhis2_connection("DHIS2_PLAY")
>>> dhis = DHIS2(con)
Outside an OpenHEXA workspace, a connection can be manually created using the SDK by providing the instance URL, an username and a password.
>>> from openhexa.sdk.workspaces.connection import DHIS2Connection
>>> from openhexa.toolbox.dhis2 import DHIS2
>>> # initialize a new connection outside an OpenHEXA workspace
>>> con = DHIS2Connection(url="https://play.dhis2.org/40.0.1", username="admin", password="district")
>>> dhis = DHIS2(con)
If needed, the OpenHEXA SDK dependency can be bypassed by providing a namedtuple instead of a Connection object.
>>> from collections import namedtuple
>>> from openhexa.toolbox.dhis2 import DHIS2
>>> # initialize a new connection outside an OpenHEXA workspace
>>> Connection = namedtuple("Connection", ["url", "username", "password"])
>>> con = Connection(url="https://play.dhis2.org/40.0.1", username="admin", password="district")
>>> dhis = DHIS2(con)
Caching¶
Caching can be activated by providing a cache directory when initializing a new connection.
>>> from openhexa.sdk import workspace
>>> from openhexa.toolbox.dhis2 import DHIS2
>>> # initialize a new connection in an OpenHEXA workspace
>>> con = workspace.dhis2_connection("DHIS2_PLAY")
>>> dhis = DHIS2(con, cache_dir=".cache")
As of now, the library only caches instance metadata and does not handle data queries.
Read metadata¶
Instance metadata can be accessed through a set of methods under the DHIS2.meta namespace. Metadata are always returned as JSON-like objects that can easily be converted into Pandas or Polars dataframes.
>>> import polars as pl
>>> from openhexa.sdk import workspace
>>> from openhexa.toolbox.dhis2 import DHIS2
>>> # initialize a new connection in an OpenHEXA workspace
>>> con = workspace.dhis2_connection("DHIS2_PLAY")
>>> dhis = DHIS2(con, cache_dir=".cache")
>>> # read organisation units metadata
>>> org_units = dhis.meta.organisation_units()
>>> df = pl.DataFrame(org_units)
>>> print(df)
shape: (1_332, 5)

The following metadata types are supported: * DHIS2.meta.system_info() * DHIS2.meta.organisation_units() * DHIS2.meta.organisation_unit_groups() * DHIS2.meta.organisation_unit_levels() * DHIS2.meta.datasets() * DHIS2.meta.data_elements() * DHIS2.meta.data_element_groups() * DHIS2.meta.indicators() * DHIS2.meta.indicator_groups() * DHIS2.meta.category_option_combos()
Read data¶
Data can be accessed through two distinct endpoints: dataValueSets and analytics. The dataValueSets endpoint allows to query raw data values stored in the DHIS2 database, while analytics can access aggregated data stored in the DHIS2 analytics tables.
Data value sets¶
Raw data values can be read using the DHIS2.data_value_sets.get() method. The method accepts the following arguments:
-
data_elements: list of str, optional
Data element identifiers (requires DHIS2 >= 2.39) -
datasets: list of str, optional
Dataset identifiers -
data_element_groups: *str, optiona*l
Data element groups identifiers -
periods: list of str, optional
Period identifiers in ISO format -
start_date: str, optional
Start date for the time span of the values to export -
end_date: str, optional
End date for the time span of the values to export -
org_units: list of str, optional
Organisation units identifiers -
org_unit_groups: list of str, optional
Organisation unit groups identifiers -
children: bool, optional (default=False)
Whether to include the children in the hierarchy of the organisation units -
attribute_option_combos: list of str, optional
Attribute option combos identifiers -
last_updated: str, optional
Include only data values which are updated since the given time stamp -
last_updated_duration: str, optional
Include only data values which are updated within the given duration. The format is, where the supported time units are "d" (days), "h" (hours), "m" (minutes) and "s" (seconds).
At least 3 arguments must be provided: * One in the data dimension (data_elements, data_element_groups, or datasets) * One in the spatial dimension (org_units or org_unit_groups) * One in the temporal dimension (periods or start_date and end_date)
Data values are returned in a JSON-like list of dictionaries that can be converted into a Pandas or Polars dataframe.
