If the underlying struct contains a non-nil value for the given field, then the function will generate a new random string and puts it into the changeset.

The charset argument should be generated through the HypeLib.Utils.String.Generator.charsets/1 or HypeLib.Utils.String.Generator.charsets!/1 functions.

2.3.2

Added the charset argument. This gives developers more control over the used characters which should be used when generating the random string.

Validates if the given field / list of fields are not nil.

When the changeset contains a field whose value is nil, then the field will be removed from the changeset and an field specific error will be appended to the changeset.
