How to create a rails 3.1 application using mysql. The following command used to create the project with sqlite database.
rails new depot
I'd like to use mysql then sqlite. So can anyone tell me how to create a project with mysql.
Thanks
See help for rails new command
rails new --help
-d, [--database=DATABASE]
Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
# Default: sqlite3
You should use:
rails new depot -d mysql

I am trying to install an existing Ruby on Rails project locally on my dev server where I run everything on mysql... the project however was built with Postgresql in mind. I am trying to change all parameters and to run "gem install" and yarn and then setup the db with "rails db:prepare" but I got stuck as there's a gem "activeRecord-postgres_enum" which obviously I commented out... but then the db creation fails:
undefined method `create_enum' for ....
How do I resolve this? Do I need to alter the actual ruby code or is there a gem that does the equivalent for ENUMs in mysql space that the above mentioned does for Postgresql?
Can I use MySQL Workbench to create the tables and add data then import / connect that into my Rails app? My Rails app is already connected to MySQL. I am just wondering if I create tables in MySQL Workbench through the app_development schema if that will sync over to my Rails project or not and if there's a way to check to see if it worked?
You can use
rake db:schema:dump
to generate schema.rb from an existing database.
Having schema.rb, you can generate an empty initial migration and put create_table and other statements from generated schema there. Doing this will allow you to use all the relevant rake tasks just as if you developed your database "the Rails way" — via a series of migrations.
I am working on a project for Magento. I am recently using MYSQL database. I want to migrate it to MongoDB database.

So, I know that it is certainly possible to connect an already-existing MySQL database to a completely new Rails application through rake db:schema:dump and by configuring the database.yml file, as shown in a couple of Stack Overflow questions and through this blog: Ruby on Rails Tutorial: Creating a Rails Instance from an Existing MySQL DB.
However, is it possible to link an already existing scaffold in Rails 4.1 - one that is generated through say,
rails g scaffold person \
firstname:string lastname:string gender:string age:integer
(and this scaffold is generated with the default SQLite setting), and say you have a MySQL database on AWS named people with columns firstname:string lastname:string age:integer.
Is there some way to link up the rails app to this existing database in such a case?
