Full Stack Flask, React, and Postgres, pt. 1

[@sergiocanas383]

Finally found a course that talks about all three and not just React and flask. Thank you

[@tejasgopal6101]

Great video man! You're video was done smartly and concisely, I really appreciate it!

[@djthedev]

This is the best tutorial I've found on this topic. Thanks so much Chris!

[@timothyatanda1188]

Please help me, have you tried the code steps on your own?🤦‍♂🙏

[@cryswerton-silva]

Thanks for the video and please keep up with the good work!

[@jackpeterson541]

why you didn't use json dump(dumps) instead define format_event function?

[@iFunktion]

I really don't understand how you are doing this without getting errors, I am now getting :RuntimeError: Working outside of application context. How do you get round all of this?

[@giantqtipz6577]

subscribed. I went to fullstack javascript bootcamp, and used sequelize for database. But just got a job that uses JS, Python, and SQL. This is the course I need to get up to speed. Saving this to follow along later. Thanks!

[@iFunktion]

Hi, I'm getting and error: RuntimeError: Either 'SQLALCHEMY_DATABASE_URI' or 'SQLALCHEMY_BINDS' must be set. How do you get past this?

[@bigmack13]

Did you ever sort this out

[@sagharsahebi5236]

Did you figure it out?@@bigmack13

[@jhunelpenaflorida1768]

There had an error, but was able to solve by using postgresql:// instead of postgres://. Thank you.

[@Pedro-zj3fs]

Good video, but i think that middleware and backend is together, is a good option to pull apart the backend from middlware, for microservices, for example :)

[@speedbump164]

yeah, this was a great video and a huge help. you earned a like and a sub my friend

[@iFunktion]

How did anyone get this to work, tables won't create, error messages everywhere, this is a nightmare for a beginner tutorial

[@ChrisDeSilva]

Sounds frustrating. Hard to tell from the error messages alone without any other context. If you're just starting out, it's a great opportunity to lean on documentation. Check the Flask docs, search Stack Overflow for similar error messages, etc. It usually ends up being a small detail that got missed somewhere along the way. Super easy to do when following along with tutorials.

[@lbb2rfarangkiinok]

Super cute project idea :)

[@lbb2rfarangkiinok]

Also, it worked! I ended up using it for a database of my daughter's stuffed animals with images of each, and it's fantastic. All that's left is some bootstrapping and the manual labor of matching the photos.

[@uykerrykaberga]

great video

[@SophieWillson-qu3gu]

This is great, I'm having an issue with my model where the 'id' and 'created_at' default value are returning "null" - when I print "event" from the formatter method it just logs my description

[@deivide5374]

can you show us how to deploy into AWS, Azure, DigitalOcean... or where ever? been having a hard time... getting front to talk to back correctly... even after building for production. Thank you

[@PilotLu]

Great set of videos Chris...thanks! What theme are you using in vscode?

[@ChrisDeSilva]

Synthwave '84

[@sebastientroszczynski5371]

Hi Chris, Thanks for your video, so cool. In your point of view, what is the best way to pass more than one value from the front to the back end . Like I would like to filter a table on multiple values. Thank you

[@jonathanpinto2399]

just use q object in flask

[@manasahr430]

could you please make a video on flask backend ,react frontend ,microsoft sql server database (stored procedure data )

[@vijeandran]

HI, Instead of printing all the columns in GET request, How could I get only specific columns from the postgres table?

[@ChrisDeSilva]

You'd just do SELECT {COLUMN_NAME_1}, {COLUMN_NAME_2} from TABLE instead of SELECT * from TABLE

[@wtf1379]

I'm sorry maybe I'm not understanding something but what is the purpose of having both sqlalchemy and psycopg2? Sqlalchemy by itself is perfectly able to handle a postgress db.

[@ChrisDeSilva]

This SO thread might help clear things up a bit: stackoverflow.com/questions/8588126/sqlalchemy-or-psycopg2

[@aldelta19]

When you start working with these tools, the other stuff seems silly... Unless you're working for an enterprise, I guess.

[@MattVibes]

So you’re keeping the baby in the parent directory? 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@shikhxr24]

While giving the db.create_all() for creating the 'event' table, I'm getting "Runtime error: Working outside of application context" The way to resolve this is using 'application context' . I went through the documentation but couldn't figure out how the code would look like for this. Please let me know if you could.

[@ChrisDeSilva]

Without seeing the code you've got set up, this looks like it might point you in the right direction based on that error: flask.palletsprojects.com/en/2.3.x/appcontext/

[@agreen254]

You have to nest the db.create_all() inside a context block: with app.app_context(): db.create_all() Also make sure you declare the Event class before running create_all or it won't register in the database. I have no idea why it worked for him in the python shell without adding the context block. Probably something to do with the deprecation warnings, considering the video is almost 2 years old now. Still a good tutorial that helped me with ORMS!

[@theclueless11212]

When I run POST and GET requests at localhost:5000/events, I get a 401 Unauthorized error. any ideas why?

[@ChrisDeSilva]

Tricky to diagnose without a bit more detail but are you seeing any other error messages in the console. First thing that comes to mind is that you may have a CORS issue and may have simply missed that part of the setup. Happy to try to help troubleshoot further if you have more details/questions.

[@timothyatanda1188]

This is a great tutorial i must be sincere, but many of found it hard to setup Python with VS code powershell, you shouls have started from how you create your folders😭

[@joeniati7903]

what commands should i runto start the project

[@joeniati7903]

does this use any kind of JWT token?

[@joeniati7903]

or any kind of tokens?

[@joeniati7903]

This project will not start for me properly

[@techany671]

Githhub link?
