AbstractDataContext
- class great_expectations.data_context.AbstractDataContext(runtime_environment: Optional[dict] = 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:

add_data_docs_site(site_name: str, site_config: DataDocsSiteConfigTypedDict) None#
Add a new Data Docs Site to the DataContext.
New in version 0.17.2.
Example site config dicts can be found in our “Host and share Data Docs” guides.
- Parameters
site_name – New site name to add.
site_config – Config dict for the new site.
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, str]#
Build Data Docs for your project.
- Relevant Documentation Links
- Parameters
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
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
ClassInstantiationError – Site config in your Data Context config is not valid.
