Ecto.Changeset.validate_confirmation
You're seeing just the function
validate_confirmation
, go back to Ecto.Changeset module for more information.
Specs
Validates that the given parameter matches its confirmation.
By calling validate_confirmation(changeset, :email)
, this
validation will check if both "email" and "email_confirmation"
in the parameter map matches. Note this validation only looks
at the parameters themselves, never the fields in the schema.
As such as, the "email_confirmation" field does not need to be
added as a virtual field in your schema.
Note that if the confirmation field is nil or missing, this does not add a validation error. You can specify that the confirmation parameter is required in the options (see below).
Options
:message
- the message on failure, defaults to "does not match confirmation":required
- boolean, sets whether existence of confirmation parameter is required for addition of error. Defaults to false
Examples
validate_confirmation(changeset, :email)
validate_confirmation(changeset, :password, message: "does not match password")
cast(data, params, [:password])
|> validate_confirmation(:password, message: "does not match password")
