Question

我想在这些行中仅在RSpec测试期间创建一个DataMapper模型。但是如何在RSpec测试中创建底层的temp_models表？

require 'spec_helper'

class TempModel
  include DataMapper::Resource
  property :id, Serial
  property :foo, String
end

describe "MyTests" do
  before(:all) do
    # what goes here to create the table and finalize the model?
  end
  after(:all) do
    # what goes here to drop the table?
  end
  before(:each) do
    TempModel.destroy!
  end

  it 'creates a TempModel' do
    expect { TempModel.create(:foo => "yowza")}.to_not raise_error
  end
end

所以，就像代码所说的那样，我在before(:all)块中放置什么来在db中创建表并创建DataMapper模型？并在after(:all)块中删除表格？

或者，如何创建“本地迁移”并对其进行上下移动？

我挖掘了各种来源，并尝试提出这个解决方案。如果有人对此有所改进，请告诉我：

require 'spec_helper'

class TempModel
  include DataMapper::Resource
  property :id, Serial
  property :foo, String
end

describe "MyTests" do
  before(:all) do
    DataMapper.auto_upgrade!
    TempModel.finalize
  end
  after(:all) do
    adapter = DataMapper.repository(:default).adapter
    adapter.execute("DROP TABLE #{TempModel.storage_name}")
  end
  before(:each) do
    TempModel.destroy!
  end

  it 'creates a TempModel' do
    expect { TempModel.create(:foo => "yowza")}.to_not raise_error
  end
end

如何为RSpec测试创建临时DataMapper模型？
