cakephp bootstrap ui validation error messages not showing

I needed my CakePHP 3 application to automatically show the validation errors next to the coresponding FriendsOfCake/bootstrap-ui inputs. Here's what was the key point: you have to pass the corresponding model table instance, that contains those errors, into the $this->Form->create() call.

For example:

// in your controller
$user = $this->Users->newEntity();
if ($this->request->is('post')) {
    $user->set(array(
        // ... set you data to save
    ));
    $this->Users->save($user);
    debug($user->errors); // to confirm
}
$this->set('user', $user);

// in your .ctp file
$this->Form->create($user);

Bootstrap's tooltips on iOS require a double tap to activate

There's a problem with Bootstrap's tooltip plugin: when used on a smartphone, it requires a double tap to trigger an element it is attached to. For example, I had a tooltip added to a button. The first tap would show the tooltip, but to actually trigger the button I had to tap it one more time, and that wasn't obvious.

I searched for a solution online, and found a bug report closed by maintainers claiming that it wasn't an issue, and the solution was to not use the tooltips (?!).

Here's a workaround I ended up using:

jQuery(document).ready(function(){
jQuery("label[data-toggle=tooltip]").on('show.bs.tooltip', function (e) {
    if ('ontouchstart' in document.documentElement) {
        e.preventDefault();
    }
});
