Question

这是我使用ERB的代码。它不能绑定TestCase对象 ERB是否可以与对象绑定一起使用？ TestReport类中有两种方法。如果您注释Testcase对象绑定，则代码将按预期工作。如果我尝试绑定对象，则会出现以下错误。 TestCase的“在'get_binding'中阻止：未定义的方法ID”。

require "erb"enter code here

# Build template data class.
class TestcaseReport

   def initialize(platform)
   @platform = platform
   @testcases = [ ]
   @features = [ ]
   end

  def add_testcase(testcase)
    @testcases << testcase
  end

   def add_feature(feature)
    @features << feature
  end

    # Support templating of member data.
  def get_binding
    binding
  end
end


class TestCase
  def initialize(id, link, name, testcasetype, time, status )
    @id = id
    @link = link
    @name = name
    @testcasetype = testcasetype
    @time = time
    @status = status
  end
end

Answer 1

发生问题是因为您的TestCase类没有id实例方法。要创建此方法，您只需将attr_reader :id添加到您的类中。

class TestCase
  attr_reader :id

  def initialize(id, link, name, testcasetype, time, status )
    @id = id
    @link = link
    @name = name
    @testcasetype = testcasetype
    @time = time
    @status = status
  end
end

添加此内容后，调用<%= t.id %>时代码不会出错

'get_binding'未定义的方法“ id”
