classmethod _create(project_root_dir: Optional[PathStr] = None, runtime_environment: Optional[dict] = None) SerializableDataContext#

Data Context

Parameters
  • project_root_dir – path to the root directory in which to create a new great_expectations directory

  • usage_statistics_enabled – boolean directive specifying whether or not to gather usage statistics

  • runtime_environment – a dictionary of config variables that override both those set in config_variables.yml and the environment

Returns

DataContext

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.
