I got my Rails 4 app running on my local machine and on heroku at the moment. Now I tried to set up an ubutunu 14 server. For deployment I am using capistrano and the connection between my local machine and the server is already set. Currently I am trying to do the initial deploy with this command:
cap production deploy:initial
I get following error at a certain point:

production:
adapter: postgresql
database: deploy
pool: 5
timeout: 5000
username: USER
password: PASSWORD
So as far as I can see it, the gemfile and database.yml should be fine. Can anyone find the mistake(s) I made? I found a few other threads that worked this topic but they didn't help in my case.
Ok, I found the solution.
Since I was using windows on my local machine, rails used this version of pg:
//Gemlock.lock
pg (0.18.4-x86-mingw32)
Changing it to
//Gemlock.lock
pg (0.18.4)
and pushing it to the git solved my problem.

I was able to reproduce your error in a dummy Rails 4.2.6 app with your Gemfile and database.yml. I couldn't even push the app to Heroku without raising LoadError: cannot load such file -- mysql2.
I fixed the problem by removing the mysql2 gem from the development and test groups and adding it to the default group. My guess is that running bundle install locally adds it as a dependency to Gemfile.lock which is checked into git and pushed to Heroku. Heroku doesn't install the gem and when the app tries to require it a LoadError is raised.
group :test do
gem 'byebug'
end
group :development do
gem 'web-console', '~> 2.0'
end
gem 'mysql2', '>= 0.3.13', '< 0.5'
A couple notes: if you want to add one gem to two or more specific groups, do not specify them separately. This just means there are two places where you're going to have to remember to change your version dependencies. So instead of this
group :test do
gem 'byebug'
gem 'another_gem'
end
group :development do
gem 'web-console', '~> 2.0'
gem 'another_gem'
end
do this
group :test do
gem 'byebug'
end
group :development do
gem 'web-console', '~> 2.0'
end
group :development, :test do
gem 'another_gem'
end
Also, you shouldn't use MySQL locally and PostgreSQL in production, just use Postgres for both. They are not fully compatible, so you are bound to run into confusing issues down the road. Your best solution to this problem would be to remove mysql2 altogether and configure your dev and test databases for Postgres.
i can push to heroku just fine.. however when I run a rake i get this error:
PG::ConnectionBad: could not connect to server
I can run locally ok so not really sure why I am having trouble pushing to heroku - any help would be great
I suspect this is related to my database.yml file:
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#
default: &default
adapter: postgresql
pool: 5

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.

You should not commit database.yml into heroku:
When Rails applications are deployed to Heroku a database.yml file is
automatically generated for your application that configures
ActiveRecord to use a PostgreSQL connection and to connect to the
database located at DATABASE_URL. This behavior is only needed up to
Rails 4.1. Any later version contains direct support for specifying a
connection URL and configuration in the database.yml so we do not have
to overwrite it.
Read heroku documentation about this.
I am trying to deploy my first rails application on digital ocean in Ubuntu, I am unsure if I am doing this right. I initially had my production database in postgres and test and production in sqllite. In frustration, I changed all my databases to postgres my changing the database.yml. I am unsure if I did that correctly But I had this error: ActiveRecord::StatementInvalid (SQLite3::ReadOnlyException: . When I was in sqllite. I was not sure if I had to tell the server to switch to production mode or if it was configured to use sqllite.
What I want to do is use postgres instead of sqllite. I am using nginx and Unicorn. MY database is blank so I dont need to transfer anything. I have made the postgres database within postgres, I just need to point my app to that database. (I am unaware if I need to do something else
I have used this database.yml

Run rake db:drop db:create db:drop to drop your old database(s) and recreate the new ones in Postgres.
I'm trying to teach myself ruby on rails and I'm trying to create a simple application to start with. I'm following the tutorial at http://guides.rubyonrails.org/getting_started.html#creating-a-new-rails-project but am having difficulty starting the server. When I try start up the server and go to the localhost,
Could not load 'active_record/connection_adapters/sqlite3_adapter'. Make sure that the adapter in
config/database.yml is valid. If you use an adapter other than 'mysql', 'mysql2', 'postgresql' or
'sqlite3' add the necessary adapter gem to the Gemfile.
I'm tried to look up a solution/reason why this happens on other questions but to no avail.

I'm using
Ruby 2.1.3
and when I type
gem list
I find I'm running
rails 4.1.6
sqlite3 (1.3.9 x86-mingw32)
Can anyone point me in the right direction?
Make sure your config/database.yml has an appropriate database driver set for current environment:
development:
adapter: sqlite3 # check if you have sqlite3 here
encoding: ...
database: ...
pool: ...
username: ...
password: ...
Also don't forget to set it for all other environments you want to use sqlite3 in.
I've never used sqlite but from the error I'm guessing you have a line in database.yml that says:
adapter: sqlite3_adapter
that should instead be:
adapter: sqlite3
Edit: ninja'd
You can put your sqlite3 gem to development in Gemfile
group :development do
gem 'sqlite3'
//*Your other gem to only development
end
wrong adapter in your database.yml file.
use this:
adapter: sqlite3
I just started a Rails 4 app from scratch with the intention to use Postgres. I went and changed the database.yml file to the following:
development:
adapter: postgresql
encoding: unicode
database: personalapi_dev
pool: 5
username: nickoneill
password:
host: localhost
# 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: &test
adapter: postgresql
encoding: unicode
database: personalapi_test
pool: 5
username: nickoneill
password:
host: localhost
Yet when I run rake db:create it gives me the following error:
uninitialized constant ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::PG

I've tried everything from upgrading the Postgres gem, making sure Postgres is running, etc, yet not sure why it's not working. I have other rails apps (including Rails 4) on my computer that run just fine yet this new one won't work. Any ideas?
