I watched this video few months ago and It was so difficult to understand but I'm happy I comprehend it now. Thank you, Anthony, for what you do for the Flask community.

Thank you so much for your videos! Hours of reading documentations, but you can answer my questions in a few minutes. 🥰

[@shraddhapatil4070]

Can you please make a video on uselist parameter and share it across. Thanks in advance

[@tasoulman]

Great video as always. keep up the good work. I have two questions 1) When using 'joined' lets say in your example and I want to print these fields in a template, do I still have to write a double for loop to access Pet's fields ? 2) I have DebugToolbar installed and I have noticed that too many queries are executed. I think that you showed how to we can fix this but I cannot find the video.

[@prettyprinted]

Yeah, if you're starting from an arbitrary person and you want to get their pets, then you'll need two loops. For too many queries being executed, it depends completely on which queries are being executed and why. It's solved more by moving the queries around or removing them completely.

[@tasoulman]

Ok, two loops it is. I mean that I see the same query executing as many times as the results

[@tasoulman]

Any answer to my last question ?

[@prettyprinted]

Hey, sorry for the delay. I answer comments in bulk every few days. Could you send me an example so I could take a look? [e-mail]

[@tasoulman]

Any clue ? anyone ? I think you made a video about this but I can't find it

[@mustaphab32]

A question please : whene using lazy dynamic : an appenderquery isnt the same as a base query , why dont they make a pagination for AppenderQuery to use it as we can use it for BaseQuery , that will be good is there any way to use pagination on a relation when lazy=dyanmic ? thank you for your amazing help

[@ReallyHighoncarbs]

Hey ! I see that you are using wsl , do you figure out a way to use venv setup in wsl on windows ? So that sublime text can work with that venv

[@prettyprinted]

I haven't look into combining the two yet.

[@ReallyHighoncarbs]

Pretty Printed if you find a solution do post a video about it

[@cheetosthrash]

hey man, first off, thank you for your video, it's very informative. but i wonder if you can help me with something, what if i wanted to fetch a pet, with it's owner, how can it be done?
