CSVSchema

✓ from pycsvschema import CSVSchema

✗ from pycsvschema import CSVSchema

Load a schema from YAML, create a CSVSchema instance, and validate a CSV file.

import yaml from pycsvschema import CSVSchema schema_yaml = """ fields: - name: id type: integer constraints: required: true - name: name type: string """ schema = yaml.safe_load(schema_yaml) validator = CSVSchema(schema) with open('data.csv', 'r') as f: errors = validator.validate(f) for error in errors: print(error)

csvschema --version

Debug

Known issues

gotchaPyCSVSchema expects the schema in Python dict form (parsed from YAML/JSON), not a raw string. Passing a schema string directly will raise a TypeError.

fix

Parse the schema using yaml.safe_load() or json.loads() before passing to CSVSchema.

affects: all

breakingIn v0.0.6, the library switched from CSVValidator class to CSVSchema. Importing CSVValidator from pycsvschema no longer works.

fix

Use CSVSchema instead of CSVValidator. Change imports and constructor calls.

affects: >=0.0.6

deprecatedUsing 'validate()' with a file path string is deprecated; always pass a file object (opened via open()).

fix

Use with open('file.csv') as f: validator.validate(f) instead of validator.validate('file.csv').

affects: >=0.0.5
