AbstractDataContext

Signature

class great_expectations.data_context.AbstractDataContext(
runtime_environment: Optional[dict] = None,
user_agent_str: Optional[str] = None
)

Base class for all Data Contexts that contains shared functionality.

The class encapsulates most store / core components and convenience methods used to access them, meaning the majority of Data Context functionality lives here.

One of the primary responsibilities of the DataContext is managing CRUD operations for core GX objects:

Signature

add_data_docs_site(
site_name: str,
site_config: DataDocsSiteConfigTypedDict
)None

Add a new Data Docs Site to the DataContext.

Example site config dicts can be found in our "Host and share Data Docs" guides.

Parameters

NameDescription

site_name

New site name to add.

Config dict for the new site.

build_data_docs

Signature

build_data_docs(
site_names: list[str] | None = None,
resource_identifiers: list[great_expectations.data_context.types.resource_identifiers.ExpectationSuiteIdentifier] | list[great_expectations.data_context.types.resource_identifiers.ValidationResultIdentifier] | None = None,
dry_run: bool = False,
build_index: bool = True
)dict[str,

Build Data Docs for your project.

Relevant Documentation Links

Parameters

NameDescription

site_names

if specified, build data docs only for these sites, otherwise, build all the sites specified in the context's config

resource_identifiers

a list of resource identifiers (ExpectationSuiteIdentifier, ValidationResultIdentifier). If specified, rebuild HTML (or other views the data docs sites are rendering) only for the resources in this list. This supports incremental build of data docs sites (e.g., when a new validation result is created) and avoids full rebuild.

dry_run

a flag, if True, the method returns a structure containing the URLs of the sites that would be built, but it does not build these sites.

build_index

a flag if False, skips building the index page

Returns

TypeDescription

dict[str, str]

A dictionary with the names of the updated data documentation sites as keys and the location info of their index.html files as values

Raises

TypeDescription

ClassInstantiationError

Site config in your Data Context config is not valid.
