ActiveRecordHelper
The ActiveRecordHelper
class seems intent on providing the fastest possible path from an
ActiveRecord object to an HTML representation. These methods may be
useful for putting together very quick demonstrations or for debugging
purposes, but they arenât likely to be your best choice for
application-building. (In general, FormHelper
and FormTagHelper
are better choices for
building forms.)
error_message_on
Returns a
div
containing the error message for a given object and method. You can add text before or after the message.error_messages_for
Returns a
div
containing all the error messages for a given object. (The documentation suggests that you look at the code and make your own method if you need something more specific.)form
Creates a POST-based form based on the ActiveRecord object, all in one call. You can add extra pieces to the form through a block, but mostly this is good for quick-and-dirty instant forms.
input
Creates an input element based on the type of the object and method itâs passed. Itâs kind of like a field-by-field version of form.
