Instance Method Details

#translate(namespace, attribute, postfix: nil, default: '') ⇒ Object

Lookup translations for the given namespace using I18n, based on model name, and attribute name.

Lookup priority with nested attributes:

form.{namespace}.{model}/{attribute.first}.{attribute.last}
form.{namespace}.{attribute.first}.{attribute.last}
form.{namespace}.{model}.{attribute.last}
form.{namespace}.defaults.{attribute.last}
{default}

Lookup priority without nested attributes:

form.{namespace}.{model}.{attribute}
form.{namespace}.defaults.{attribute}
{default}

Namespace is used for :labels and :hints.

Model is the actual object name, for a @user object you’ll have :user. Attribute is the attribute itself, :name for example, or [:user, :name] if nested.

If :postfix is given, it will be appended to the end of each lookup entry. So with a :postfix of ‘stuff’, ‘_stuff’ will be appended:

form.{namespace}.{model}.{attribute}_{postfix}
