Django Template Language

Quick reference

• 00:04 All right, in this video I want to start to talk about
• 00:04 the Django template language.
• 00:05 And we've already kind of looked at these a couple of videos here.
• 00:09 Now this is opening and closing tags.
• 00:11 And, I've showed you a couple of things that we can do.
• 00:15 We created these links using those.
• 00:18 We created this block content that allowed us to do our base.html stuff.
• 00:22 But I haven't really talked about what in the world these things are.
• 00:26 So when you have web frameworks like Django, like Ruby on Rails, like node,
• 00:30 most of the time those frameworks have an underlying programming language.
• 00:34 So for Django for instance, the underlying programming language is Python.
• 00:39 For Ruby on Rails, the underlying language is Ruby.
• 00:43 For node, the underlying language is JavaScript.
• 00:46 So, all of these things usually have template languages that allow you
• 00:51 to sort of use the programming language with the framework.
• 00:55 So for instance here, the Django template language sort of allows
• 01:00 us to use Python on our web-pages and that's really, really cool.
• 01:04 So we're seeing just little snippets of this here and
• 01:07 we're going to get into much more detail in the next few videos
• 01:10 of all the cool things we can do with the Django template language.
• 01:14 So, I want to show you just really quickly, head over to your web browser and
• 01:19 let's just type in Django template language.
• 01:22 And the first thing that pops up is going to be the the Django documentation.
• 01:26 And I haven't mentioned it before, but you can check out docs.djangoproject com/.
• 01:32 These are the Django documentation,
• 01:33 there's all kinds of cool stuff in here you can read.
• 01:36 But right now we just want to quickly kind of look at this page,
• 01:39 this Django template language and here's the URL for that.
• 01:42 You can see there's things we've already done, extends base and block things.
• 01:46 And here's a title thing, we'll talk about that in a bit.
• 01:49 What I want to really show you down here is variables.
• 01:51 One of the main things that programming language does is work with variables.
• 01:56 And think of variables as boxes, you can put stuff in them, right?
• 01:59 So to be able to use Python variables on a Django web page is pretty huge and
• 02:04 you can do that.
• 02:05 You'll notice these tags are just a little bit different.
• 02:08 Our original tags, we've been using in the last few videos have these curly brackets,
• 02:14 open and close, and these percentage signs open and close.
• 02:17 But when you use variables, you don't use those percentage signs,
• 02:21 you just do double curly brackets.
• 02:23 I'll show you this going forward.
• 02:25 You can see down here, we're doing a four loop, this is a Python thing.
• 02:29 There's all kinds of stuff, you can use filters, different tags,
• 02:33 comments if you wanted to.
• 02:35 All kinds of stuff and you can see this is a pretty big web-page,
• 02:39 there's a lot of stuff here.
• 02:41 And we're going to get into all of this in greater detail in the coming videos here.
• 02:47 But for this video, I just want to kind of point it out, show you this resource if
• 02:50 you're interested in really learning this stuff in much greater detail.
• 02:53 Like I said, I'm going to talk about a lot of this stuff in the next few videos,
• 02:57 the most important parts that you really want to focus on and learn.
• 03:01 But if you want to dive deeper, you can always come here and check this out.
• 03:04 So in the next video, we'll dive in here a little bit deeper.
• 03:07 We'll start to learn about block titles, why they're important and
• 03:10 some of the cool things you can do with it.
• 03:12 And that will be in the next video.
