Python Django Tutorial: Deploying Your Application (Option #2) - Deploy using Heroku

[@thatsamoore4007]

Corey, I first watched this series a couple months ago because I wanted to learn Django for fun. Well since then, I've ended up with a new IT job and decided to build a relatively simple Django app for some of our purposes. The things I learned from this series were invaluable and I even referenced back to some things during development when I forgot how to do them. I just got everything working enough for production today and showed it to my boss. He absolutely loved it. Thank you so much for this wonderful series. I look forward to learning more from you in the future.

[@coreyms]

Congrats on your new job and your project!

[@dh00mketu]

@Crebs Park you there?

[@mohit4u007]

@Crebs Park from the requirements.txt remove everything after = sign. Means keep the names of the packages but remove the version number. Pip will pick up the latest version package. This will work for this simple app but not if you have developed something with specific verion number in mind.

[@alexradu1921]

@Crebs Park yes that's the best way to learn... also integrate Git in all the stuff you do (it changed my life tbh)

[@Alexander-re8vz]

@@coreyms Hello Corey I have a problem with my Django so when I deployed it to Heroku I made a new field in post and then when I migrated it on the Heroku server and pushed it an error occurred, now I deleted that field but when I pushed it this error occurred: django.db.utils.IntegrityError: column "pinned" of relation "blog_post" contains null values It looks as tho that field is saved now getting deteted

[@juvewan]

Just finished all 17 of the Django series, although the videos were created in 2018-19, they are the best I found to get started with Django. Thanks Corey for explain and demo Django so clearly!

[@AJ-tr4jx]

"django has deployment checklist on their website that you can lookthrough.." 1 minute later: "this actually reminds me that we havent set Debug=False yet" damn this is GOOD.. you really proved your point

[@egae6782]

on 40:00 you can also do same "pip freeze > requirements.txt" on windows. It works exactly the same

[@amartyadas5-yriddmechanica597]

Corey, You are the best. When I pass out of college and get a job I will remember to pay my tribute. Thank you !!

[@danielcallaghan6892]

I fell into a bit of depression during my diploma course at the beginning of December because I was just not getting Django. I'm almost finished with my project for school now and it looks great - I'm happy with it. I never would have gotten it done if it wasn't for this tutorial series. I went through many of the videos 2-3 times - amazing teacher - thanks so much.

[@Piotrus1990]

It is the best heroku turtorial available online.( I checked lots of them but nothing helped me as much as You did ) Everything explained step by step, clear. You doing amazing job with Your turtorials man!!!!

[@leandroleveron9933]

You are by far, the best teacher I've had. I just finished your series and deployed my web app. Thanks for sharing your wisdom.

[@EvuLYT]

God Bless Corey Schafer. I embarked on a Python/Django mission at the start of this month and this tutorial helped me get started with Django. I just spent the last 2 days trying to deploy and it's been hell but after making some corrections and following this video step by step I finally got my project deployed. I learned a ton and am absolutely amazed by the amount of detail you go into with these tutorials. Thank you so much for all that you do in helping novice programmers like myself.

[@LifeofthePRTY]

You are a G.O.A.T./unsung hero. Words cannot describe how invaluable you are to me and the rest of the community. You taught me how to develop my own website using Django from scratch/zero knowledge and now I'm successfully/confidently deploying my own website with Heroku. It is a milestone having completed this video and looking back on my journey starting with your first video on learning Django with Python. Thank you so much, you're an incredible teacher and human being Just thought I should post this

[@ronithNR]

Teachers like you makes the world a better place to live.

[@Drzfinest929]

Corey I just want to say THANK YOU SO MUCH! I've been working on my very first freelance project and decided it would be a good idea to learn Django (never touched python) to create the backend for the project and I struggled so very much during this process but I have to admit you have saved me on many many and I really do mean many errors. I hope you find this comment well and I hope it makes you feel like you made a difference in at least in one beginner programmer. I couldn't have done it without you, thank you so much once again!

I thought this Series were done, I'm just in the third lesson but since this was months ago thats what I thought! Nice to see that you keep updating this series Corey. Please can you go a bit deeper with Django and talk about Redis+Celery? or Maybe Rest? Maybe you already talked about this, but since I'm still in the third lesson I havent notice.

Thanks for the videos! You are my favorite youtube tutorialist :) I did major part of your Django series. I followed along, all went smooth and maybe too smoth. Eventually I quitted because I felt like I am not learning, I am just following what you write. Some weeks ago it came back when applying to a Junior Engineer position and I did a small project in Django. I didn't have to open the documentation even once and I remembered everything from the Django series! Really well done, thanks.

For those who are getting errors related to the collectstatic, I think you should consider looking at your CSS file if you have and avoid referencing images from the URL that is outside of your apps, in the base directory.

This is awesome! I didn’t follow along with your entire course, but I found this video so useful. I was able to host my first mid-sized Django project by following along with this video. Initially, I had issues hosting on Pythonanywhere because of the Cloudinary SDK I was using to host all image uploads, but this worked for me. I’m pretty familiar with Heroku for apps I’ve hosted in other languages but this totally helped since it was my first time hosting a Django project. Thank you, Corey!

Just to clarify something, on 44:20 when I type 'python manage.py createsuperuser' --> 'django.db.utils.OperationalError: no such table: auth_user' (an error poped up like that). So I found out that in 'settings.py', the DATABASES section still using sqlite3: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } So I changed to: DATABASES = { 'default': { 'ENGINE': dj_database_url.config(conn_max_age=600, ssl_require=True) } } --> commit and deploy to heroku again --> re-run 'makemigration', 'migrate', 'createsuperuser' on heroku and then no more errors.

I have benefitted so much from these tutorials...Thank you so much Corey! I have one confusion, since the Heroku repo is our production, shouldn't the DEBUG_VALUE set at 31:26 be changed to False in the end? Anyways, for beginners, I think deploying using Heroku feels much more intuitive than using Linode although it lacks the flexibility that Linode has (plus it's free :) ).

You are right. You have to input "heroku config:set DEBUG_VALUE='False'" into the terminal to disable Debug mode on the live version of the website. gg

Hey Corey, this was the most detailed tutorial on heroku deployment I`ve watched so far on youtube. The best thing about it is the step-by-step errors and warnings solutions.

[@jordanhyatt9490]

Firstly, Absolutely phenomenal series. This is how I cut my teeth in Django. Small comment for this video specifically Env Vars. I find its better to set the env vars somewhere specific to that project rather than the system level.... simply because if i am developing 10 django projects managing all 10 dev env variables at the system level becomes very annoying and impractical....ananconda has a way of setting env vars that are env specific but maybe a video is in order on best way to do it in general??

5:53 There's people who say it doesn't matter. Why would it be best to keep it to the project's specifications? Does it take up too much space? If you have unlimited space, wouldn't it better to just install everything and not have to worry about it later?

[@GPBrachetta]

Dear Corey, your series are great and you are extremely pedagogical and clear! Wonderful! Are you planning to carry on with the series?

Be careful if you have used both pip and pipenv to install packages! In my case, Heroku was deploying using my pip.lock file but I haven't updated it in a long time. So although my requirements.txt file was current, I kept bumping into errors because Heroku says the packages don't exist. Solved this by pipenv installing from my current requirements.txt file generated by the pip freeze > requirements.txt command (Refer to Corey's Pipenv video for a refresher if unfamiliar). Now my app is successfully deployed. A long but worthwhile learning journey for me!
