Hey John! I hope you are doing well. Can I please ask for an AWS implementation of the database? Even if its just hooking it up and doing basic things with it. I just really love AWS and use it for other projects and I'd like to be able to follow along with your tutorials and knowing how you do the things on railway, but I do it on AWS? (even if it is just a random side-video completely outside of the series)
Hello I am Abhi from India and I watch your videos because I get to learn a lot from them. You made a video on deploy. I have many projects which are ready for deployment and there are many videos also but I am not able to understand their content.
where are the videos to finish this project ? I have finished video 43 and I thought that there would be more, such as the payment system and launching the site from github.
Even when I delete orders from the Django Admin payment>Orders area, the order numbers do not reset. For example, if I had 10 orders previously, then deleted all of them and created a new order after filling out the form, it assigns the new order number as 'Order - 11' instead of 'Order - 1'. How can I reset this issue?
You don't. That's not how databases work, and that's not how you would want it to work. Otherwise many people could have the same order number, and you don't want that.
hi sir !! heroku free hosting isnt available anymore can you please point me towards something similar which I can use to deploy my project online and just get a website link ??
I am having this stupid eror and ı couln't find any solution yet! So ı write here as well. if anybody knows how to fix this error. please help me out UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xf6 in position 79: invalid start byte I checked any explanation but none works and again thank you for the course sir!!
I have been dealing with this for more than a day now and still persists. I couldn't find more or understand why. So by all means if anybody knows. Reach out!
@@Codemycom I trust your judgement John Elder. To me it matters because I'm more familiar with MySQL even though the process is the same. Postgres here I go
@@TheLummen. Yeah, django abstracts away the database layer anyway so you're not using mysql or postgres syntax...so you're right, it's all the same...

Hello John, I followed along and set up my code as provided by you. But I am encountering an error repeatedly. I looked for answers in the railway community, but in vain.

Please let me know if you are aware of any solutions. Thank You
@@Codemycom Hey John, I was able to migrate. PGHOST always shows error. And in my effort to solve the issue, I encountered that a lot of users have been facing the issue. What worked for me is - Settings section provides the Public Networking option to connect with TCP using a proxied domain and port. Hope I should share.

thank you john and The site is slow before add postegres
that's a matter of your own computer speed since the original database ran on your computer not the cloud where postgres runs...

Hello I am Abhi from India and I watch your videos because I get to learn a lot from them. You made a video on deploy. I have many projects which are ready for deployment and there are many videos also but I am not able to understand their content.
We'll begin deploying the site in the next video
Can I use MySQL instead of Postgres in this course ?
You can use anything you want anytime you want
python decouple can be used instead?
only one way to find out
Sir, do i understand correctly that we're doing this to make the website accessible online to anyone?
yes
where are the videos to finish this project ? I have finished video 43 and I thought that there would be more, such as the payment system and launching the site from github.
This is an ongoing playlist, new videos come out every Wednesday...hence the name Django Wednesdays.
Please make a problem solving playlist!!
I don't know what that is
Even when I delete orders from the Django Admin payment>Orders area, the order numbers do not reset. For example, if I had 10 orders previously, then deleted all of them and created a new order after filling out the form, it assigns the new order number as 'Order - 11' instead of 'Order - 1'.

You don't. That's not how databases work, and that's not how you would want it to work. Otherwise many people could have the same order number, and you don't want that.
