如何使用 Rails 在一次调用中保存这个数组?
tax_rates = [{
:income_from => 0
:income_to => 18200
:start => "01-07-2013"
:finish => "30-06-2014"
:rate => nil
:premium => nil
},{
:income_from => 18201
:income_to => 37000
:start => "01-07-2013"
:finish => "30-06-2014"
:rate => 0.19
:premium => nil
},{
:income_from => 18201
:income_to => 37000
:start => "01-07-2013"
:finish => "30-06-2014"
:rate => 0.19
:premium => nil
}]
我可以打电话Rails.create(tax_rates)
吗?
另外,有没有办法删除重复的符号,让它们看起来更整洁?
