Adding Firebase data, dots and forward slashes

Question

I try to use firebase db, I found very important restrictions, which are not described in firebase help or FAQ.

First problem is that symbol: dot \'.\' prohibited in

Answer 1

Personally, I found a simple and easy hack for this same problem I encountered

I took the dateTime string and convert it using replace('/','|')

the result will be something like this 2017|07|24 02:39:37 instead of 2017/07/24 02:39:37.
