URLs

Quick reference

• 00:04 Okay, so we've got our views, we've got our templates.
• 00:06 Now, we need a URL.
• 00:08 And if you look in our resume directory, there's no urls.py file and
• 00:13 that's kind of a problem.
• 00:14 So let's head over to our Django web directory.
• 00:17 If you look in here, there is a urls.py file.
• 00:20 So let's open that.
• 00:21 Now, I'm going to get rid of all of these comments, we don't need them.
• 00:26 Go ahead and save it.
• 00:27 Now, this is the main urls.py file for our project and
• 00:32 we need a separate urls.py file for our specific resume app, all right?
• 00:38 So that's what we're going to work on now.
• 00:41 So first things first, we need to tell our main project that our resume app exists.
• 00:48 So to do that, we go to our settings.py file and
• 00:50 scroll down till you see INSTALLED_APPS.
• 00:53 Remember, we created an app, we called it resume.
• 00:56 So we need to designate that right here.
• 00:57 So just come down here, hit Enter to go to the next line, put single quotation marks,
• 01:02 and then just type in resume, and then put a comma at the end.
• 01:06 Now, Ctrl+S to save this file or come up here to File, Save.
• 01:10 All right, so now our main Django website project knows
• 01:15 that a resume site or resume app exists.
• 01:18 So that's step one.
• 01:19 Next, we need to come down to our resume directory and right click and
• 01:24 create a new file.
• 01:26 When it pops up, let's go to File, Save As, and let's save this as urls.py.
• 01:33 So you can see, boom, it pops up right there.
• 01:35 So now, we need to tell our original urls.py file that's inside
• 01:41 the Django website directory that this new urls.py file exists.
• 01:46 And it seems a little complicated, but it's not too bad, and
• 01:50 we'll only have to do this once.
• 01:51 So what we do is, let's go ahead and
• 01:54 close all of these because this can be confusing.
• 01:59 So we want to come to our Django website urls.py file and
• 02:02 the first thing we want to do is add the include module.
• 02:06 So we type include up here.
• 02:08 So we want to import path and we want to import include.
• 02:12 And include allows us to include other files and that's exactly what
• 02:17 we want to do, we want to include this new urls.py file in our old urls.py file.
• 02:23 So we add include.
• 02:25 So now, we want to come down here to our urlpatterns and
• 02:29 hit Enter, and then tab over, hit the Tab key on your keyboard,
• 02:34 and we want to create a new path.
• 02:37 So we type in path and then parentheses and
• 02:41 single quotation marks and then the colon.
• 02:46 And now, the single quotation marks means our home page, which is localhost:8000.
• 02:53 It doesn't have a slash, anything after it.
• 02:56 Remember when we looked at the admin section, it had a slash admin next to it.
• 03:00 In fact, here's the URL for that right there.
• 03:02 We just want the home page to redirect to this new urls.py file.
• 03:08 So we put single quotation marks and then a comma and
• 03:13 then we want to include quotation marks,
• 03:18 single quotation marks, resume.urls, all right?
• 03:23 And that's what this file is here.
• 03:24 It's in resume.urls, all right?
• 03:30 So then, we want to put a comma after here and we're good to go.
• 03:35 So now, let's save this file, Ctrl+S, we come up to File, Save.
• 03:40 And next, we want to copy all of this stuff, just Ctrl+C or
• 03:44 you can right click and copy.
• 03:45 And we want to close this file and then head over to our new urls.py file that's
• 03:50 empty and you can right click and click Paste.
• 03:53 Now, we can get rid of this and we don't need to do include.
• 04:00 Now, let's come through here and get rid of those.
• 04:03 Okay, so this is our new urls.py file, go ahead and save this.
• 04:07 And from now, on every time we create a new URL for a new webpage in our app,
• 04:12 we'll do it here in this urls.py file.
• 04:15 To create a path for any webpage, we just come down here,
• 04:18 make sure you're tabbed over, do not space over.
• 04:21 You want to tab over, very important, and then just type in path.
• 04:26 And then, we want this to be the home page, so it's just empty, and then comma.
• 04:32 Now, point this to our views file.
• 04:35 So we type in views.home,
• 04:39 and then give it a name.
• 04:44 Name=, let's just call it home.
• 04:46 So now at the end, we want to put a comma.
• 04:49 So go ahead and save this.
• 04:50 Now, this views.home, this is referencing our views.py file and
• 04:55 our home function that we created a couple of videos ago, right?
• 05:00 So essentially, we're just pointing our home page or
• 05:03 home URL, which is nothing, to views.home and we've named it home.
• 05:08 Now, why do we have to name these things?
• 05:10 We'll talk about it later on when we look at links.
• 05:12 But for now, just realize every time you create a URL,
• 05:15 you just have to give it a name.
• 05:17 And it really doesn't matter what the name is, but we're creating a home page,
• 05:21 so we're going to call it home.
• 05:23 And it's going to point to our views.home,
• 05:26 which is views.home, which itself points to home.html.
• 05:32 So it's a three step process.
• 05:33 It's all kind of circular, it all references itself.
• 05:36 Now, we have to do one more thing to our urls.py file and
• 05:40 we have to import our views because right here, we're referencing views.
• 05:44 We haven't actually imported that.
• 05:45 So up here at the top, we just type in
• 05:49 from.import views and go ahead and save that.
• 05:54 Now, the period means from this directory.
• 05:56 So we're in our resume directory, we're saying from inside of this directory,
• 06:01 import views, which is just our views.py file.
• 06:05 So we go ahead and save it.
• 06:06 Now, if we come back to our app and hit Reload,
• 06:11 we see this is my home page Woohoo,
• 06:14 which if we come back here and look in our templates file and
• 06:19 our home page, is this exact thing right here.
• 06:24 So if you see this congratulations, we've created our first webpage and yeah,
• 06:28 that's really, really cool.
• 06:30 I know it's a little bit convoluted the three step process, the view,
• 06:34 the template, and the URL, but
• 06:36 you really only have to kind of wrap your brain around at once.
• 06:40 And after that,
• 06:40 it becomes very easy a as you'll see going forward when we add new pages.
• 06:44 So that's all for this video.
• 06:46 In the next video, we'll look at extending a base file.
• 06:48 I'll tell you what that's all about and that will be in the next video.
