Answer 1

在分貝/ seeds.rb試試這個執行原始的SQL與耙分貝：種子

connection = ActiveRecord::Base.connection() 
connection.execute("*_YOUR_SQL_HERE_*") 

Answer 2

對於多個SQL聲明，我最終分別重複了每條語句：

# db/seeds.rb 

connection = ActiveRecord::Base.connection() 

sql = <<-EOL 
    INSERT INTO users values ('Admin'); 
    INSERT INTO categories values ('Supervisors'); 
EOL 

sql.split(';').each do |s| 
    connection.execute(s.strip) unless s.strip.empty? 
end 

Answer 3

在弗雷德裏克博斯特倫的答案的變化，可以從文件加載：

# db/seeds.rb 

def execute_sql_file(path, connection = ActiveRecord::Base.connection) 
    require 'active_support/core_ext/object/blank.rb' 
    IO.read(path).split(';').reject(&:blank?).each do |statement| 
    connection.execute(statement) 
    end 
end 

execute_sql_file('my.sql')
