[linebreaks][1]

Replaces line breaks in plain text with appropriate HTML; a single newline becomes an HTML line break (`&lt;br /&gt;`) and a new line followed by a blank line becomes a paragraph break (`&lt;/p&gt;`).

For example:

&lt;pre&gt;{{ value|linebreaks }}&lt;/pre&gt;

If value is `Joel\nis a slug`, the output will be `&lt;p&gt;Joel&lt;br /&gt;is a slug&lt;/p&gt;.`

Don&#39;t use `{% autoescape off %}` ! Otherwise user controlled input may not get escaped, which is a security risk. As mentioned use [linebreaks or linebreaksbr][1].

I had a text area for user minimal custom input in the template and I wanted to keep whatever formatted text the user inserted to stay the same.
The solution, I simply changed the Model variable to a TextField type. It even shows the user formatted text in the admin. :)

ex.
    
    class Uadds(models.Model):
    	title		= models.CharField(max_length = 50)
    	description	= models.TextField(max_length = 1000)

title will not show line breaks, however, description will show them.
I haven’t tested this with a Rich Text Editor...
Hope this helped.

Use `{% autoescape off %} {{ your_variable }} {% endautoescape %}`.


I have this code:

    $.ajax({
            url : url,
            data : {ids : JSON.stringify(jsonids), hotel_id: hotel_id},
            success : function(response)
            {
                $(&#39;#be-images ul&#39;).prepend(response).fadeIn(&#39;slow&#39;);
            },
            dataType: &#39;html&#39;
        });

but the fade In does not work...I want the content to be prepended and faded in...how will I do this?

Thanks in advance!

Does anyone know of a good guide for creating a project with the new 2.0 release of GWT using maven and eclipse? I am running into a lot of problems getting them to play nicely together. 

For what it&#39;s worth, I can create a gwt project using the maven eclipse plugin which works fine, but porting it to maven doesn&#39;t work (so a guide for this would be great). 

Likewise, I can use the maven plugin (gwt-maven-plugin), but when I import it to eclipse (import -&gt; materialize maven projects), it does not get recognised as a GWT project...

Thanks

How do I allow line breaking in textarea input in django to later show this input on page?

Django: allow line break from textarea input

Is there a CSS-only way to style a `&lt;select&gt;` dropdown?

I need to style a `&lt;select&gt;` form as much as humanly possible, without any JavaScript. What are the properties I can use to do so in CSS?

This code needs to be compatible with all major browsers:

- Internet Explorer 6, 7, and 8
- Firefox
- Safari

I know I can make it with JavaScript: [Example][1].

And I&#39;m not talking about simple styling. I want to know, what the best we can do with CSS only.

I found [similar questions][2] on Stack&amp;nbsp;Overflow.

And [this one][3] on Doctype.com.

As the question indicates, if I have some text that I want to add in the HTML then when should I use `&lt;p&gt;` and when should I use `&lt;span&gt;`?

When to use &lt;span&gt; instead &lt;p&gt;?

Is it possible to stack up multiple DIVs like:

    &lt;div&gt;
    &lt;div&gt;&lt;/div&gt;
    &lt;div&gt;&lt;/div&gt;
    &lt;div&gt;&lt;/div&gt;
    &lt;div&gt;&lt;/div&gt;
    &lt;/div&gt;

So that all those inner DIVs have the same X and Y position? By default they all go below each other increasing the Y position by the height of the last previous DIV.

I have a feeling some sort of float or display or other trick could bite?

EDIT: The parent DIV has position relative, so, using position absolute does not seem to work.

Stacking DIVs on top of each other?

I have a text input. A value is populated into it when the page loads. If the user changes anything in text box, then I want to get the changed value (the new value) and old value. But calling `ELEMENT.value` it only returns the changed/new value.

How do I get the old value?

Here is my code:

```html
      &lt;head&gt;
        &lt;script type=&quot;text/javascript&quot;&gt;
          function onChangeTest(changeVal) {
            alert(&quot;Value is &quot; + changeVal.value);
          }
        &lt;/script&gt;
      &lt;/head&gt;
      &lt;body&gt;
        &lt;form&gt;
          &lt;div&gt;
              &lt;input type=&quot;text&quot; id=&quot;test&quot; value =&quot;ABS&quot; onchange=&quot;onChangeTest(this)&quot;&gt;  
          &lt;/div&gt;
        &lt;/form&gt;
      &lt;/body&gt;
```

How to get old Value with onchange() event in text box

I have some JavaScript code that communicates with an XML-RPC backend.
The XML-RPC returns strings of the form:

    &lt;img src=&#39;myimage.jpg&#39;&gt;

However, when I use the JavaScript to insert the strings into HTML, they render literally. I don&#39;t see an image, I literally see the string:

    &lt;img src=&#39;myimage.jpg&#39;&gt;

My guess is that the HTML is being escaped over the XML-RPC channel.

How can I unescape the string in JavaScript? I tried the techniques on this page, unsuccessfully: http://paulschreiber.com/blog/2008/09/20/javascript-how-to-unescape-html-entities/

What are other ways to diagnose the issue?


Unescape HTML entities in JavaScript?

The django books gives the local trick in order to avoid to type a long list of parameters as context dictionnary

http://www.djangobook.com/en/2.0/chapter04/


Example:

```
def current_datetime(request):
    dt_now = datetime.datetime.now()
    return render_to_response(&#39;current.html&#39;, {&#39;dt_now&#39;: dt_now})
```

becomes:

```
def current_datetime(request):
    dt_now = datetime.datetime.now()
    return render_to_response(&#39;current.html&#39;, locals())
```

It recommends this to lazy programmers but points out some overhead which may have an impact on performance.

I would like to know if some of you are using the locals trick on real applications. Do you recommend it or is it a bad practice?

Django template and the locals trick

I have a couple of functions that I wrote that I need to use in my django app. Where would I put the file with them and how would I make them callable within my views?

Django: Where to put helper functions?

My `views.py` has become too big and it&#39;s hard to find the right view.

How do I split it in several files and then import it? Does it involve any speed loss?

Can I do the same with `models.py`?

Split views.py in several files

My local machine is running Python 2.5 and Nginx on Ubuntu 8.10, with Django builded from latest development trunk.

For every URL I request, it throws:

&gt; TemplateDoesNotExist at /appname/path appname/template_name.html
&gt; 
&gt; Django tried loading these templates, in this order:
&gt; * Using loader django.template.loaders.filesystem.function:
&gt; * Using loader django.template.loaders.app_directories.function: 
&gt; 
&gt; TEMPLATE_DIRS 
&gt; 	(&#39;/usr/lib/python2.5/site-packages/projectname/templates&#39;,)

Is it looking for **/usr/lib/python2.5/site-packages/projectname/templates/appname/template_name.html** in this case? The weird thing is this file does existed on disk. Why can&#39;t Django locate it?

I run the same application on a remote server with Python 2.6 on Ubuntu 9.04 without such problem. Other settings are the same.

Is there anything misconfigured on my local machine, or what could possibly have caused such errors that I should look into?

In my **settings.py**, I have specified:

    SETTINGS_PATH = os.path.normpath(os.path.dirname(__file__))
    # Find templates in the same folder as settings.py.
    TEMPLATE_DIRS = (
        os.path.join(SETTINGS_PATH, &#39;templates&#39;),
    )

It should be looking for the following files:

 - /usr/lib/python2.5/site-packages/projectname/templates/appname1/template1.html
 - /usr/lib/python2.5/site-packages/projectname/templates/appname1/template2.html
 - /usr/lib/python2.5/site-packages/projectname/templates/appname2/template3.html
 - ...

All the above files exist on disk.

**Solved**

It works now after I tried:

    chown -R www-data:www-data /usr/lib/python2.5/site-packages/projectname/*

It&#39;s strange. I don&#39;t need to do this on the remote server to make it work.

Django TemplateDoesNotExist?

When researching Google App Engine (GAE), it&#39;s clear that using Django is wildly popular for developing in Python on GAE.  I&#39;ve been scouring the web to find information on the costs and benefits of using Django, to find out *why* it&#39;s so popular.  While I&#39;ve been able to find a wide variety of sources on *how* to run Django on GAE and the various methods of doing so, I haven&#39;t found any comparative analysis on *why* Django is preferable to using the webapp framework provided by Google.

To be clear, it&#39;s immediately apparent why using Django on GAE is useful for developers with an existing skillset in Django (a majority of Python web developers, no doubt) or existing code in Django (where using GAE is more of a porting exercise).  My team, however, is evaluating GAE for use on an all-new project and our existing experience is with TurboGears, not Django.

It&#39;s been quite difficult to determine why Django is beneficial to a development team when the BigTable libraries have replaced Django&#39;s ORM, sessions and authentication are necessarily changed, and Django&#39;s templating (if desirable) is available without using the entire Django stack.

Finally, it&#39;s clear that using Django does have the advantage of providing an &quot;exit strategy&quot; if we later wanted to move away from GAE and need a platform to target for the exodus.

I&#39;d be extremely appreciative for help in pointing out *why* using Django is better than using webapp on GAE.  I&#39;m also completely inexperienced with Django, so elaboration on smaller features and/or conveniences that work on GAE are also valuable to me.
