Summary

The package contains common ecto helpers:

Changeset validators

• EctoCommons.DateValidator:
  • validate_date(changeset, field, opts): validates an equality (with approximation), before or after a given date.
• EctoCommons.DateTimeValidator
  • validate_datetime(changeset, field, opts): validates an equality (with approximation), before or after a given date time.
• EctoCommons.TimeValidator
  • validate_time(changeset, field, opts): validates an equality (with approximation), before or after a given time.
• EctoCommons.EmailValidator
  • validate_email(changeset, field, opts): validates emails. As there is no perfect validation possible, multiple options are available depending on your requirements. Can also reject temporary/burner emails.
• EctoCommons.URLValidator
  • validate_url(changeset, field, opts): validates if an URL is correct. Here too, there is no perfection possible. Multiple options are available depending on the precision required.
• EctoCommons.StringValidator
  • validate_has_prefix(changeset, field, opts): validates if a string starts with a given prefix. The prefix itself can depend on another field or on a dynamic value.
• EctoCommons.PostalCodeValidator
  • validate_postal_code(changeset, field, opts): validates postal code formatting using regular expressions depending on the country. This only ensures the postal code “looks ok” but doesn’t check it really exists (that will need a complete database of all postal codes worldwide).
• EctoCommons.SocialSecurityValidator
  • validate_social_security(changeset, field, opts): validates social security numbers (SSN) depending on the country. This only validates french SSNs for now.
• EctoCommons.LuhnValidator
  • validate_luhn(changeset, field, opts): validates a string with Luhn’s algorithm such as credit card numbers and other administrative codes.
• EctoCommons.PhoneNumberValidator
  • validate_phone_number(changeset, field, opts): validates a phone number using libphonenumber.

Changeset helpers

• EctoCommons.Helpers
  • validate_many(changeset, field, opts): validates multiple fields with the same validation function as well as the same options.
