/**
* Implementation of hook_view().
*/
function course_view($node, $teaser = FALSE, $page = FALSE) {
$node = node_prepare($node, $teaser);
$node->content['course'] = array(
'#value' => theme('course_info', $node),
'#weight' => 1,
);
return $node;
}

I have written a simple code from drupal.api to show the node data created by user. The problem I am facing is that the data is inserting inside the database but hook view is not implementing the data showing capability.

Can any one suggest how to implement the hook view() .What precautions we have to take to implement the hook_view(). Sorry for my wrong english.
