Link to this function construct_message(field, error_tuple) View Source

Generate a single Kronky.ValidationMessage struct from a changeset.

This method is designed to be used with Ecto.Changeset.traverse_errors to generate a map of structs.

## Examples

```
error_map = Changeset.traverse_errors(fn(changeset, field, error) ->
  Kronky.ChangesetParser.construct_message(field, error)
end)
error_list = Enum.flat_map(error_map, fn({_, messages}) -> messages end)

```
Link to this function extract_messages(changeset) View Source

Generate a list of Kronky.ValidationMessage structs from changeset errors

For examples, please see the test cases in the github repo.

Link to this function interpolate_message(arg) View Source

Inserts message variables into message.

Examples 

iex> interpolate_message({"length should be between %{one} and %{two}", [one: "1", two: "2", three: "3"]})
"length should be between 1 and 2"
Link to this function messages_as_map(changeset) View Source

Extract a nested map of raw errors from a changeset

For examples, please see the test cases in the github repo.

Link to this function to_code(arg) View Source

Generate unique code for each validation type.

Expects an array of validation options such as those supplied by Ecto.Changeset.traverse_errors/2, with the addition of a message key containing the message string. Messages are required for several validation types to be identified.
