I can't do heroku push. ruby on rails - ruby-on-rails

I did git push heroku master then I got error below
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.example.com
So I did heroku logs --tail to find out the problems then I got below
enable Logplex by exmaple#mail.com
Release v2 created by example#mail.com
Slug compilation failed: failed to compile Ruby
I don't know how to fix this issue and push heroku well. need your help!

Can you make sure you've added
gem 'rails_12factor', group: :production
To your gem file and run
Bundle install
Followed by git add . and git commit -am "something"
And try to push again.

Having trouble pushing an app to Heroku

I'm in the process of pushing a webapp I designed in Rails to Heroku, but I'm having trouble when pushing the app to heroku. According to the console, when it starts preparing the app for the Rails asset pipeline, the rake aborts. At the end I get this error:
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/connectr-demo.git'
I have heard that this is because of conflicts in the commits, but I have already pulled from github and everything is up to date, or at least the console is reporting so. At the recommendation of a similar question, I tried using "git fetch origin" and "git pull --rebase" but got the exact same results. I still get this error when I try to push to heroku. Can anyone tell me how I can fix this?
Is it a fast-forward merge, or do you need to force push?
Try git push -f heroku master...
Have you tried running heroku run rake db:migrate and then try re-pushing to heroku git push heroku master
The (pre-receive hook declined) means that Heroku didn't recognize the app. Make sure that the rails app is in the root directory of the repo not in a sub directory, make sure you have a Gemfile and make sure that it is named correctly.

Getting Error while pushing into Heroku (Precompiling assets failed.)

Note: I am using Rails 3.2.13 and Ruby "1.9.3", and postgres-0.15.1
I tried to push my Ruby on Rails app in to heroku by following the procedure this website
http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-deploying
, but I got error while try to push into heroku
Connecting to database specified by DATABASE_URL
rake aborted!
could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
! Precompiling assets failed.
! Push rejected, failed to compile Ruby app
To git#heroku.com:pure-hamlet-9148.git
! [remote rejected] master -> master (pre-receive hook declined)
So, I Googled myself and run the below command
heroku labs:disable user-env-compile
heroku labs:enable user-env-compile
Still getting the same error, please some help me to resolve this issue.
Along with Simone's answer,
Follow this website to precompile your assets locally before deploying. https://devcenter.heroku.com/articles/rails-asset-pipeline
RAILS_ENV=production bundle exec rake assets:precompile
git add public/assets -f
git commit -m "vendor compiled assets"
Check this article about Heroku and Rails asset:precompile error. You should set
config.assets.initialize_on_precompile = false
A way to resolve this error:
First of all set DATABASE_URL environment variable & then again tried to push code to Heroku again. And it worked as all rake compilation done at Heroku side so no more connection to local machine making rake compilation # .../tmp/bin..... directory.

Ruby on Rails Precompiling assets failed

I've been following the reInteractive ruby on rails (15 min blog), and in the end of the post (second part), I got an error using heroku to upload my files:
! Precompiling assests failed
!Push rejected, failed to compile Ruby app
To git#heroku.com:peaceful-sea-8032.git
! [remote rejected] master -> master <pre-receive hook declined>
error: failed to push some refs to 'git#heroku.com:peaceful-sea-8032.git'
ps: The app runs fine on localhost, I saw some similar question but I did not have success trying their solutions.
Precompile your assets locally. In your shell cd to your application folder and enter:
RAILS_ENV=production bundle exec rake assets:precompile
This will precompile your assets locally
Then you have to
git add .
git commit -am 'precompiled assets'
git push heroku
(eddited last line)

Heroku push giving me "no Cedar-supported app detected error"

I'm trying to push my RoR to Heroku for the first time (I'm a newbie on this stuff!)
The error that I'm getting is:
-----> Heroku receiving push
! Heroku push rejected, no Cedar-supported app detected
To git#heroku.com:calm-retreat-9405.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git#heroku.com:calm-retreat-9405.git'
Double check if you committed correctly your Gemfile and config.ru
