Firebase ~ looping through users and sending letters












0














How this would work. So, I have Firebase. I have a Table called Letters. Letters consist of:



How Database "Letters" Table looks like



So what I'm trying to tell you with this is, how would I check whenever the person sends a letter, the letter checks first if the person receiving has the right age? If the person does not have the right age, It looks for another match in the Friends table until it finds one, with like the given value of they're age.



Later I can also check if the genders match and if the person receiving hasn't already had the same letter or gets the letter twice.



Problem:
How can I loop through a Friends table and check the user_id's age and once the loop found a match for the same age range it locks the matched user_id into the Letters? Basically, if the first match is over the max age limit. It continues looping till it finds an age in between the min-max.
