Most users nowadays familiar with AJAX, well they don’t really know the term.
What users familiar is the experience, such as of submitting form without reloading the page.

So when you build new website or your web application, don’t forget to include this experience. But you also have to remember, there are some people who turn off their javascript or maybe the javascript failed to load. That is why, you should consider to use progressive enhancement.

How Django template work

In Django template you can’t mix programming logic into template, and this is by the design, because basically template is meant to express presentation. But of course, Django template provide something called tags which function similarly to some programming constructs. Now let’s go through some real example how Django template work.

In Django template we use {{ variable }} to express variable.

6

<html>
    <head><title>{{ page.title }}</title></head>
    <body>
        {{ page.body }}
    </body>
</html>

To loop over array or list we use for tag

9

<html>
    <head><title>{{ page.title }}</title></head>
    <body>
    {% for news in news_list %}
    <h2>{{ news.title }}</h2>
    <p>{{ news.content }}</p>
    {% endfor %} 
    </body>
</html>

And to simulate selection, Django template provide if tag

<html>
    <head><title>{{ page.title }}</title></head>
    <body>
    {% if message %}
    {{ message }}
    {% endif %}
    </body>
</html>

Me : Hmm, well so far I just play with GD only for creating thumbnail or crop an image. What exactly do you mean by that?

My friend : I need to crop an image and need the result in ellipse, so there will be an ellipse showing part of the image, and outside that ellipse should be transparent.

Me : What do you need that for?

My friend : Hmm, well just for some project I’m currently handle.

Me : I promise you nothing, but I’ll give it a shoot. Continue reading »
