You did a clear explanation in one video while firebase guys in their channel are trying to do the same in many many episodes. Well done. Thank You.

[@tristangrobler4950]

Great tutorial, I really needed the "Making rules for a specific location" section. Works like a charm now in my database !!!!!

[@dennisgonzales9521]

Finally! I was having a hard time figuring out what rules ahould i use for my database! Thanks 😘

[@brightli2745]

Thank you so much. This really helped, espiaclly the wild card explanation. I found some docs on how to use the rules, but without pictures of the database, it was hard to understand. Keep up the good work

[@cesarc5930]

Hi Nico! It was the best tutorial I´ve found on the Internet. I really apreciate! Thanks for your dedication and keep doing this great job!

[@SaptadeepDutta_Ex-Xerox]

[@5445jedi]

I'm reposting my comment because somehow it got deleted. Thanks for these super helpful videos, Nico. Your advice is very helpful and detailed. One thing you may want to consider is turning off the background music because it can be distracting during the lessons. Other than that, these videos are awesome.

[@patrickojeh]

Bro, you just saved a life. Thank you!

[@anthonyrunstedler]

It would be very helpful to show the rules, paired with example data to show the nesting and how rules are applied. An example of reading / writing to a database with some lockdown in place would be helpful as well.

[@rameeshariz7070]

i want go give some user Special permission to write to a folder like (Sp_Adim) if they have a custom UID . to give permission all custom UID saved in a folder in real time data base how can i check this "Newdata.child('S_uid').val === root.child(\"$folder\")" i tried its not working even the folder are inside there Cust_uid/sdsd get denied root.child('Cust_uid').child(\"$custom_id\").exists() === 'sdsd' What am I doing wrong?

[@uNicoDev]

Sorry for the late reply. If I understand what you wrote correctly, in the first case you are comparing a value (.val) to a data location (so that might be why it always returns false). In the second case, you are comparing a boolean (from the exists() method) to a string
