configuration - The parameter app_id is required on Heroku omiAuth facebook Integration -


i getting error "the parameter app_id required" when test facebook login in app. guess has configurations. can please check configuration files , let me know if there error. set app id , secret on heroku 

heroku config:set facebook_app_id=133333333463066                 facebook_secret=a7244e333333333a7a2bf9492a6089a0

here omniauth initializer file : config/initializer/omniauth.rb

omniauth.config.logger = rails.logger rails.application.config.middleware.use omniauth::builder provider :facebook, env["facebook_app_id"], env["facebook_secret"] end

my devise initializer has following line:

config.omniauth :facebook, "facebook_app_id" , "facebook_secret"

what doing wrong ?

on localhost, getting error instead: 

{  "error": {   "message": "missing client_id parameter.",   "type": "oauthexception",   "code": 101  }

}

https://graph.facebook.com/oauth/authorize?  client_id=&redirect_uri=http%3a%2f%2flocalhost%3a3000%2fusers%2fauth%2ffacebook%2fcallback&response_type=code&scope=email&state=223cbab26ab10640a2c1fe62508aecb94ffc2854721703de

as can see, client id empty in url.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
