有没有办法从现有的一组模型生成 Rails 夹具？

我有一个没有测试的 Rails 2.x 应用程序。我可以手动编写测试，但是有没有办法自动生成装置？如果不必手动输入所有内容，那就太好了。

我可以为所有模型再次运行脚本/生成，但一切都已经存在，如果我正确理解生成器，我仍然需要输入所有属性。

我考虑过运行 Rails 控制台并执行以下操作...

>> y VendorUser.all.rand

这会给我一些包含所有属性的 YAML，但它们会乱序，而且仍然非常耗时。

谁能建议一个更有效的选择？

原文

I have a Rails 2.x app with no tests. I can write out the tests manually, but is there a way to generate fixtures automatically? It would be nice to not have to type all that out by hand.

I could run script/generate again for all the models, but everything already exists and if I understand generators correctly, I'd still have to type in all the attributes.

I thought about running the Rails console and doing for example...

>> y VendorUser.all.rand

That would give me some YAML with all the attributes, but they'd be out of order and it's still pretty time-consuming.

Can anyone suggest a more efficient option?

这是一个生成灯具的 rake 任务。

desc "extracting data for fixtures"
task :extract_fixtures => :environment do
  sql  = "SELECT * FROM %s"
  skip_tables = ["schema_info","schema_migrations"]
  ActiveRecord::Base.establish_connection
  (ActiveRecord::Base.connection.tables - skip_tables).each do |table_name|
    i = "000"
    File.open("#{RAILS_ROOT}/test/fixtures/#{table_name}.yml", 'w' ) do |file|
      data = ActiveRecord::Base.connection.select_all(sql % table_name)
      file.write data.inject({}) { |hash, record|
        hash["#{table_name}_#{i.succ!}"] = record
        hash
      }.to_yaml
    end
  end
end

Here is a rake task to generate fixtures.

desc "extracting data for fixtures"
task :extract_fixtures => :environment do
  sql  = "SELECT * FROM %s"
  skip_tables = ["schema_info","schema_migrations"]
  ActiveRecord::Base.establish_connection
  (ActiveRecord::Base.connection.tables - skip_tables).each do |table_name|
    i = "000"
    File.open("#{RAILS_ROOT}/test/fixtures/#{table_name}.yml", 'w' ) do |file|
      data = ActiveRecord::Base.connection.select_all(sql % table_name)
      file.write data.inject({}) { |hash, record|
        hash["#{table_name}_#{i.succ!}"] = record
        hash
      }.to_yaml
    end
  end
end
