can we update the all left data index in counting form? like 1,2,3,4 id I have if I delete id 2 then my left id is 1,3,4 but I want to see these ids in counting form like 1,2,3
Great explanations. One question you might be able to answer : If I use your instructions to delete all rows with a certain condition like this : delete_q = Alert.query.filter_by(instructor=chosen_student).delete() print(delete_q) db.session.commit Then delete_q will return 2, but... when I do a select query on the table, the rows are NOT deleted ?! Any idea why that is ?
Very informative video! You're awesome Anthony! Can you make videos on algorithms and data structures (linked list and stuff) using python? Algorithms are taught mostly using java, c/c++. Thanks! ✌🏼
Great work!!!. I really appreciate it. Your videos are very helpful for me to understand not only Flask and Alchemy but also Python itself.
Thanks for the video! What about bulk insert statements?
Many thanks Antony, a clear explanation of CRUD which I understood on first pass due to your excellent commentary. Cheers
I'm glad i could help. Thanks for watching!
HI, Instead of printing all the columns in GET request, How could I get only specific columns from the postgres table?

How do you pass a subquery in the filter for updates?
Great explanations.

Can you please make a video for multiple filter conditions? By the way this video's are really helpful... Thanks!
Thanks for the tutorial, but what about using variables instead of static values?, Because I'm trying that and can't make it work.
