rails passenger deployment - Could not find table 'users' - ruby-on-rails

Question

I made the passengers's offical tutorial with no error. I pull my code from git and used this commands
bundle install --deployment --without development test
bundle exec rake assets:precompile db:migrate
my database.yml
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: db/test.sqlite3
production:
adapter: sqlite3
database: db/production.sqlite3
log/production.log:

You should be able to solve this by simply running the following:
RAILS_ENV=production bundle exec rake db:migrate
However, I don't advise you use SQLite in production, as this type of database is best for testing and development purposes. You might want to look into using PostgreSQL. The following should work for you:
in your Gemfile, add:
gem 'pg', :group => :production
Run bundle install.
Then in database.yml use:
default: &default
adapter: postgresql
encoding: unicode
pool: 10
timeout: 5000
login: &login
username: <%= ENV['DATABASE_USER'] %>
password: <%= ENV['DATABASE_PASS'] %>
production:
<<: *default
<<: *login
database: your_database_name
For security reasons, it's best not to write your database username and password in plaintext within files in your Rails app. Far better to set them as environment variables. To do this, edit the ~/.bash_profile file on your Droplet and add the following:
export DATABASE_USER=your_username
export DATABASE_PASS=your_password
Exit that file and run source ~/.bash_profile from the command line to load these new settings into memory.
You will then need to create the PostgreSQL database, for which there are plenty of guides online.
Once that's done you will want to run the same command that works for SQLite when running migrations in production:
RAILS_ENV=production bundle exec rake db:migrate
Hope this helps!
