migrate
You can try this..
Check your config/database.yml file.
your config/database.yml must look like and username, password should be change your mysql's username, password..
default: &default
adapter: mysql2
encoding: utf8
pool: 5
username: username
password: password
socket: /var/run/mysqld/mysqld.sock
development:
<<: *default
database: uBuild-rails_development
test:
<<: *default
database: uBuild-rails_test
production:
<<: *default
database: uBuild-rails_development
username: username
password: password
Also check you Gemfile
gem 'mysql2', '< 0.3' # as stated above
I had the same problem, what I did was to create the project again using this command:
rails new my_project -d=mysql
This way the configuration in database.yml and gemfile is created automatically avoiding problems. You only need to edit database.yml mysql password after this you can use
rails g scaffold Examples attrib1:string attrib2:string
to create views etc
rake db:create
to create the database and then
rake db:migrate
hope this helps...
Database file is in config/database.yml and configuration be
default: &default
adapter: mysql2 #if use postgres the add postgresql
pool: 5
timeout: 5000
username : username #mysql username
password : password #mysql password
development:
<<: *default
database: application_name
test:
<<: *default
database: application_name
production:
<<: *default
database: application_name
Run following command to setup database:
run rake db:create
run rake db:migrate
I'm trying to start an application on ruby on rails with postgresql but I'm fairly new and unfamiliar with the process. I'm running into a password error when I try to launch the rail server on localhost:3000. Here is the error I'm getting.
fe_sendauth: no password supplied
# connected server's characteristics.
def connect
#connection = PGconn.connect(#connection_parameters) <!-- This line says there's an issue -->
configure_connection
rescue ::PG::Error => error
if error.message.include?("does not exist")
Anyone know how I can set up the username and password on windows or what I need to do to get around this error?
config/database.yml
development:
adapter: postgresql
encoding: utf8
pool: 5
username: postgres
password: postgres_password
database: development_db
production:
adapter: postgresql
encoding: utf8
pool: 5
username: postgres
password: postgres_password
database: production_db
When I try to run bundle exec rake db:setup ,It gives me this error
and when I change the adapter to my username I got the same error
PG::InsufficientPrivilege: ERROR: permission denied to create database

I can't put the whole error here
and here is the database.yml code

production:
<<: *default
database: freelance_camp_documents_production
username: freelance_camp_documents
password: <%= ENV['FREELANCE_CAMP_DOCUMENTS_DATABASE_PASSWORD'] %>
PG::InsufficientPrivilege: ERROR: permission denied to create database
The problem here is you don't have sufficient privileges to user freelance_camp_documents on Postgres.
I will suggest to change permissions for user freelance_camp_documents from postgres or just change username to postgres
production:
<<: *default
database: freelance_camp_documents_production
username: postgres
password: <%= ENV['FREELANCE_CAMP_DOCUMENTS_DATABASE_PASSWORD'] %>
postgres user has permissions by default so you don't need to change anything
I got some problems with my rails_admin gem in the production when I trying make first user admin in Rails console.
In the development all works fine. Look at the error and code.
Error terminal:

To run rails console in the production environment you should use bundle exec rails console production or bundle exec rails console RAILS_ENV=production, the command bundle exec rails console run console in the development env by default.
Create the database table and do
rake db:migrate RAILS_ENV=production
rails console RAILS_ENV=production
I used this command to create an app rails new guestbook
then i used :-
rails generate scaffold Person name:string
and in routes.rb i unhashed the root :to => 'people#index'
then I wrote in the address bar localhost:3000/people and I got the following error :-
ActiveRecord::ConnectionNotEstablished
ActiveRecord::ConnectionNotEstablished
Rails.root: /home/rudraksha/rbtest/gbook
please answer ASAP
Anyways, the problem is that, connection is unable to establish with database.
Have you configured you database.yml as per you database? If not you have to configure it first.
If you are using mysql, you have to install mysql gem by adding it to your gemfile and running bundle install and configure database.yml accordingly.
Example of database.yml with mysql:
development:
adapter: mysql
encoding: utf8
reconnect: false
database: <db_name>
pool: 5
username: <your_mysql_username>
password: <your_mysql_password>
host: localhost
production:
adapter: mysql
encoding: utf8
reconnect: false
database: <db_name>
pool: 5
username: <your_mysql_username>
password: <your_mysql_password>
host: localhost
