i had a problem running bundle install with the json gem, it said:

An error occurred while installing json (1.6.6), and Bundler cannot cont
creating Makefile

make
compiling generator.c
make: gcc-4.2: No such file or directory
make: *** [generator.o] Error 1

I fixed this on my system by running this:

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

I found the solution on stack overflow.

You should probably filter out password_confirmation in the Users#create params. Right now, it creates Users and exposes the password in the password_confirmation field on Users.

I'm trying to add fields to the user which should match a Number col and a Datetime col in the Parse DB, however I can only send strings which raises a 111 invalid key error.

I managed to do a to_i in the controller but no matter the value (ex: 150) it shows as 0 in parse DB
