# FastSeeder [](http://travis-ci.org/greyblake/fast_seeder)
By [Sergey Potapov](https://github.com/greyblake)
Speed up seeding database in Rails application using multiple SQL inserts!
## Deprecation
The project is deprecated and no longer supported.
Please consider using [activerecord-import](https://github.com/zdennis/activerecord-import) instead.
## Installation
Add to Gemfile:
```ruby
gem "fast_seeder"
```
## Usage
### Seeding from CSV file
Lets say you have CSV file `db/seeds/cities/ukraine.csv`:
```csv
Kharkov,1654
Lviv,1240
Kiev,600
```
You can populate DB with it using FastSeeder:
```ruby
# Seeding from CSV file:
FastSeeder.seed_csv!(City, "cities/ukraine.csv", :name, :founded_in, :country => "Ukraine")
```
Technically it equals to:
```ruby
City.create(:name => "Kharkov", :founded_in => 1654, :country => "Ukraine")
City.create(:name => "Lviv" , :founded_in => 1240, :country => "Ukraine")
City.create(:name => "Kiev" , :founded_in => 600 , :country => "Ukraine")
```
But does the job faster using only one SQL query instead of three.
As you also noticed it expects you to pass model class, path to CSV file(located in `db/seeds`),
CSV columns, and default values.
### Seeding in place
The next example is equivalent to showed above one, but uses inline data
without CSV file:
```ruby
# Seeding in place:
FastSeeder.seed!(City, :name, :founded_in, :country => "Ukraine") do
record "Kharkov", 1654
record "Lviv" , 1240
record "Kiev" , 600
end
```
## Supported database adapters
* PostgreSQL
* MySQL(mysql, mysql2)
* SQLite3
## Running specs
```
rake spec:all # run specs with all supported adapters
rake spec:mysql # run specs with mysql adapter
rake spec:mysql2 # run specs with mysql2 adapter
rake spec:postgresql # run specs with postgresql adapter
rake spec:sqlite3 # run specs with sqlite3 adapter
```
## Rails 3
Gemfile:
```ruby
gem "fast_seeder", "0.0.2"
```
