Batch insertion in rails 3

Question

I want to do a batch insert of few thousand records into the database (POSTGRES in my case) from within my Rails App.

What would be the \"Rails way\" of doing it? So

Answer 1

You can create a script in your rails model, write your queries to insert in that script In rails you can run the script using

rails runner MyModelName.my_method_name

Is the best way that i used in my project.

Update:

I use following in my project but it is not proper for sql injection. if you are not using user input in this query it may work for you

user_string = " ('a@ao.in','a'), ('b@ao.in','b')"
User.connection.insert("INSERT INTO users (email, name) VALUES"+user_string)

For Multiple records:

new_records = [
  {:column => 'value', :column2 => 'value'}, 
  {:column => 'value', :column2 => 'value'}
]

MyModel.create(new_records)
