Answer 1

You're using the Model::read() method method which takes as the second argument the id of the row in your Model's table that you want to access. It's better to use find in this case. You don't need to build a new method in your model or your controller, you can just edit the current view method.
# in newsses_controller.php:
function view($title = null) {
$this->set('title_for_layout', __('News & Event', true));
if (!$id) {
$this->Session->setFlash(__('Invalid News.', true), 'default', array('class' => 'error'));
$this->redirect(array('action'=>'index'));
}
$this->set('newsse', $this->Newsse->find('first', array(
'conditions' => array('Newsse.title' => $title)
));
$this->set('newsses', $this->Newsse->find('all'));
}
Or, you can make a more hybrid form in which viewing by id is still possible when a numerical title is given (this assumes you never have news items which have a title consisting of only numeric characters, e.g. '12345').
# in newsses_controller.php:
function view($title = null) {
$this->set('title_for_layout', __('News & Event', true));
if (!$id) {
$this->Session->setFlash(__('Invalid News.', true), 'default', array('class' => 'error'));
$this->redirect(array('action'=>'index'));
} else if (is_numeric($title)) {
$this->set('newsse', $this->Newsse->read(NULL, $title));
} else {
$this->set('newsse', $this->Newsse->find('first', array(
'conditions' => array('Newsse.title' => $title)
));
}
$this->set('newsses', $this->Newsse->find('all'));
}
Finally, you can also replace the find method in my example with a (shorter) custom findBy method (see the documentation for more info about this).
$this->Newsse->findByTitle($title);

Answer 2

For this you need to create a new method in your model Which will display result by news title. At this time your using $this->Newsse->read(NULL,$title)). You are using $title in read method while this read method search against news id in model. So you just need to create a new method in model class like readByTitle($title){ write query here to fetch news by title }. And use this method in your controller. $this->Newsse->readByTitle(NULL,$title))
