Push Code To Heroku - Rename URL

Quick reference

• 00:04 Okay, so we've configured our app, and it's ready to be pushed up to heroku.
• 00:07 So now we want to actually push it up to heroku.
• 00:10 So head back over to our terminal.
• 00:12 And let's go ahead and clear the screen.
• 00:14 Now we've made a bunch of changes to our app.
• 00:16 So we need to save this to our Git repository both locally and
• 00:19 probably at GitHub.
• 00:20 Let's go git add.
• 00:21 git commit-am, and
• 00:24 I'll say 'configured for heroku'.
• 00:32 Okay, and then git push, to push all this code up to GitHub.
• 00:39 And now we can close the screen.
• 00:40 Now, in order to push our code from here to heroku we use the command
• 00:45 git push heroku master.
• 00:47 We're pushing the master branch, this branch right here,
• 00:51 you see this master up here.
• 00:52 This is our master git branch, pushing our master git branch to heroku, and
• 00:57 that's it.
• 00:58 So hit Enter.
• 00:59 Now, this can take a minute, it could take three minutes, it could take ten minutes,
• 01:03 it could take 30 seconds, you never rally know.
• 01:06 And this is always sort of a finger crossed type of thing because we just made
• 01:11 some configuration changes.
• 01:13 And maybe we forgot something or maybe we misspelt something.
• 01:16 One time I misspelt in the prok file, I misspelled gunicorn,
• 01:21 I typed it is gunicord, right?
• 01:24 So it threw an error, so, you're never quite sure this is always kind of hold
• 01:27 your breath and hope there's no errors.
• 01:29 And see, you can see it's installing things that psychopg that postgres
• 01:34 database, there's our dj-database-url.
• 01:36 Here's all of our stuff, really running setup.
• 01:42 Now let's see, I failed to push some references, we got an error.
• 01:46 So this is good, I always want to show an error while I'm teaching courses because
• 01:50 you're always going to get them.
• 01:52 So what you want to do when you get an error,
• 01:54 there's a couple of things you can do.
• 01:55 The first thing is just read through this stuff and
• 01:57 it looks like an overwhelming bunch of gobbledygook.
• 02:00 But you could see we're saying a python manage.py collectstatic --noinput.
• 02:04 You need to update the application code to resolve this error, or
• 02:09 you can disable collectstatic for this application by typing in this command.
• 02:15 So this is a weird one, I've seen this before.
• 02:18 Sometimes it does this, sometimes it doesn't.
• 02:20 Heroku is a little finicky that way.
• 02:22 So it's saying you can get around this by just punching in this command.
• 02:26 So let's go ahead and do that I copied it, I'm going to paste it,
• 02:30 heroku config:set, DISABLE_COLLECTSTATIC=1 and hit that, okay?
• 02:35 So now let's get push heroku master, one more time.
• 02:44 And it's going through and doing the things, and installing our dependencies.
• 02:47 And I mentioned there's a couple of things you can do.
• 02:50 You can read through this stuff.
• 02:52 You can also type in the command heroku logs to words and
• 02:56 it's just let's pull this up.
• 02:58 It's just the command heroku logs and what that will do is show your heroku logs.
• 03:03 And a lot of times if there's an error, it'll be seen in the heroku logs.
• 03:07 So that's one way you can sort of check for
• 03:10 errors if you get errors because sometimes you look through all of this stuff.
• 03:14 And you can't really tell what's wrong or there isn't an error at all.
• 03:16 Though if that's the case, you would type in heroku logs and
• 03:20 it'll show you the log file.
• 03:22 And you can see hopefully in there what you need to do.
• 03:25 And a lot of times if you do get an error in the log file or even up here,
• 03:28 you can just copy it and paste it into Google.
• 03:31 And Google will tell you immediately what you have to do to fix it.
• 03:34 So, okay, this time we've got no errors.
• 03:36 Very cool, I'm going to go ahead and clear the screen.
• 03:40 And before I do that, you can see here is our URL from a couple of videos ago when
• 03:44 we created our app, okay?
• 03:46 Clear the screen, and now is the moment of truth.
• 03:49 We can come over, this is our local app.
• 03:51 If we come over here, this is our heroku app.
• 03:54 So now we just want to click Reload and yes it worked.
• 03:58 And I'll just show you really quickly, what I mean by the heroku
• 04:02 logs we come back over here and just type in heroku logs.
• 04:09 You can see there's all this stuff and this looks overwhelming.
• 04:11 But usually, you want to look towards the end.
• 04:13 because if there is an error, it usually is shown at the very end.
• 04:17 So like from here down, I would read, if there was an error,
• 04:20 now we don't have an error, so there's no error here.
• 04:22 But if there was an error, read down here at the bottom,
• 04:25 it'll say something you probably won't understand what it says.
• 04:29 But just copy it, paste it into Google, search for it and
• 04:32 you'll usually find a Stack Overflow article.
• 04:34 Or some other article explaining what the error is, and
• 04:37 showing you exactly how to fix it.
• 04:39 So, okay, very cool.
• 04:40 We've got our, this app is now live, this is on the Internet,
• 04:43 anybody can come to this website.
• 04:45 Now, we're using the free tier of heroku which is not very powerful.
• 04:48 So if like ten people came to the site at the same time,
• 04:52 it would be very slow to load.
• 04:54 You know what I mean?
• 04:55 So if you want more powerful you can go to Heroku and
• 04:58 pay for higher bandwidth and more powerful web hosting if you want.
• 05:02 But just for this purpose of showing you how to do it, this is great works fine and
• 05:06 is very cool.
• 05:07 So we can click around it does all the things, all right?
• 05:12 Very cool, and this website is completely done John Elder tech resume.
• 05:16 So we've got this URL djangoresume2.herokuapp.com,
• 05:21 but chances are you want your own URL.
• 05:25 You want your own domain name like johnelder.com, right or whatever.
• 05:29 So how do you do that?
• 05:31 We will take look at that in the next video.
