Apparently one can’t insert two and more ‘<tr>’ elements into a ‘<tbody>’ using PrototypeJS 1.7.0.0 and 1.6.0.3 if there’s also a ‘<br/>’ element involved in the conspiracy so that code simply won’t work at all:

var new_content = 'foo
bar';
$('my-tbody').insert(new_content);

One needs to leave out the poor ‘<br/>’ and I guess that applies to inserting ‘<br/>’ in general, not only in this situation but thankfully right now I only need to dynamically add new table rows not line breaks..

So if you have a piece of YUI Javascript code similar to the one shown below

function foo() {
 
    var on_success = function(o) {
        alert('Yay!');
    };
 
    var on_failure = function(o) {
        alert('Oh ones!')
    }
 
    var callback = {
        success: on_success,
        failure: on_failure,
    };
 
    var url = '/url/to/invoke';
    var transaction = YAHOO.util.Connect.asyncRequest('POST', url, callback);
}

and the URL the AJAX call invokes returns the “CSRF verification failed. Request aborted. CSRF token missing or incorrect.” error, the easiest way to properly handle is to set the custom X-CSRFToken HTTP header to the same value the csrftoken cookie has been set by Django to, just like the Django documentation says it can be done.

In code terms, that will do the trick

function foo() {
 
    var on_success = function(o) {
        alert('Yay!');
    };
 
    var on_failure = function(o) {
        alert('Oh ones!')
    }
 
    var callback = {
        success: on_success,
        failure: on_failure,
    };
 
    var url = '/url/to/invoke';
 
    YAHOO.util.Connect.initHeader('X-CSRFToken', YAHOO.util.Cookie.get('csrftoken'));
    var transaction = YAHOO.util.Connect.asyncRequest('POST', url, callback);
}

Hoping this helps someone some day!
