Is there a way to delete all children of an parent in Mongoose, similar to using MySQLs foreign keys?

For example, in MySQL I&#39;d assign a foreign key and set it to cascade on delete. Thus, if I were to delete a client, all applications and associated users would be removed as well.

From a top level:

 1. Delete Client
 2. Delete Sweepstakes
 3. Delete Submissions

Sweepstakes and submissions both have a field for client_id. Submissions has a field for both sweepstakes_id, and client_id.

Right now, I&#39;m using the following code and I feel that there has to be a better way.

    Client.findById(req.params.client_id, function(err, client) {

		if (err)
			return next(new restify.InternalError(err));
		else if (!client)
			return next(new restify.ResourceNotFoundError(&#39;The resource you requested could not be found.&#39;));

		// find and remove all associated sweepstakes
		Sweepstakes.find({client_id: client._id}).remove();

		// find and remove all submissions
		Submission.find({client_id: client._id}).remove();

		client.remove();

		res.send({id: req.params.client_id});

	});

I just started to learn AngularJS and struggle with some concepts of AngularJS. It would be great if somebody could explain me some points...

1. I understand that `ng-click` is technically not the same as `onclick` (see [here][1]), but both are placed in the markup. I thought that would be a &quot;bad practice&quot;? Why is this one of the core concepts of AngularJS, if most people say this is &quot;bad&quot;? I thought it would be better to select the DOM element from JavaScript and not to place logic in the markup.

2. If `ng-click` is the right way to react to click events in AngularJS what should I do with other DOM events? I see that there are several other directives like `ng-mouseover`, but not all DOM events have a AngularJS equivalent. How would I handle a &#39;drop&#39; event in AngularJS (hence in the AngularJS way - not the normal way)? To be clear: I want to [drag a file into my webapp][2].

Thank you very much,
Pipo

I just updated jQuery from 1.8.3 to 1.9, and it started crashing all of a sudden.

This is my template:

    &lt;script type=&quot;text/template&quot; id=&quot;modal_template&quot;&gt;
    	&lt;div&gt;hello&lt;/div&gt;
    &lt;/script&gt;

This is how I read it:

    modal_template_html = $(&quot;#modal_template&quot;).html();

This is how I transform it into jQuery object (I need to use jQuery methods on it):

    template = $(modal_template_html);


... and jQuery crashes!

Error: Syntax error, unrecognized expression: &amp;lt;div&amp;gt;hello&amp;lt;/div&amp;gt;

slice.call( docElem.childNodes, 0 )[0].nodeType;

jquery-1.9.0.js (line 3811)

However, if I declare template as a plain text variable, it starts working again:

    var modal_template_html = &#39;&lt;div&gt;hello&lt;/div&gt;&#39;;

Can anyone help me to figure this out?


**UPDATE**:
Jquery team heard and [changed][1] things back to normal in 1.10:

&gt; The biggest change you’re likely to see is that we’ve loosened up the criteria for HTML processing in $(), allowing leading spaces and newlines as we did before version 1.9

I have some debugger statements in my module under test and want to run mocha with `--debug-brk` set and hit my breakpoint so that I can inspect the state of my module. Unfortunately, whenever I run mocha with this option, I end up with a blank cursor on the next line. I can enter text, but there&#39;s nothing that appears to be processing my commands (it certainly doesn&#39;t look like the node debugger):

    $ mocha --debug-brk tests.js -R spec
    debugger listening on port 5858
    [BLANK CURSOR]

Am I doing something wrong with how I&#39;m launching mocha?

What&#39;s the right way to enable the node debugger with mocha&#39;s --debug-brk switch?

I recently updated jQuery from 1.8 to 2.1. I suddenly discovered that the `.live()` stops working.&lt;br&gt;
I get the error `TypeError: $(...).live is not a function`.

Is there any method I can use in place of `.live()`?

jQuery 1.9 .live() is not a function

What actually the difference between this?

This works fine:

    var obj1 = jQuery.parseJSON(&#39;{&quot;orderedList&quot;: &quot;true&quot;}&#39;);
    document.write(&quot;obj1 &quot;+ obj1.orderedList );
    
but the following does not work:

    var obj2 = jQuery.parseJSON(&quot;{&#39;orderedList&#39;: &#39;true&#39;}&quot;);
    document.write(&quot;obj2 &quot;+ obj2.orderedList );

Why is that?

jQuery.parseJSON single quote vs double quote

I&#39;m a member of a team with more than 20 developers. Each developer works on a separate module (something near 10 modules). In each module we might have at least 50 CRUD forms, which means that we currently have near 500 **add buttons**, **save buttons**, **edit buttons**, etc.

However, because we want to globalized our application, we need to be able to translate texts in our application. For example, everywhere, the word **add** should become **ajouter** for French users.

What we&#39;ve done till now, is that for each view in UI or Presentation Layer, we have a dictionary of key/value pairs of translations. Then while rendering the view, we translate required texts and strings using this dictionary. However, this approach, we&#39;ve come to have something near 500 **add** in 500 dictionaries. This means that we&#39;ve breached DRY principal.

On the other hand, if we centralize common strings, like putting **add** in one place, and ask developers to use it everywhere, we encounter the problem of not being sure if a string is already defined in the centralized dictionary or not.

One other options might be to have no translation dictionary and use online translation services like Google Translate, Bing Translator, etc.

Another problem that we&#39;ve encountered is that some developers under the stress of delivering the project on-time can&#39;t remember the **translation keys**. For example, for the text of the add button, a developer has used **add** while another developer has used **new**, etc.

What is the best practice, or most well-known method for globalization and localization of string resources of an application?
