Question

在使用参数运行rake任务时，我遇到了这个问题。

C:\projects\Test1>rake test_rake_task csv_header csv_column
(in C:/projects/CyncErp)
** Invoke annotate_models (first_time)
** Execute annotate_models
krunal get_model_names
model_name = csv_header
model_name = csv_column
rake aborted!
Don't know how to build task 'csv_header'
c:/ruby/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:1728:in `[]'

c:/ruby/lib/ruby/gems/1.8/gems/rake-0.8.7/bin/rake:31
c:/ruby/bin/rake:19:in `load'
c:/ruby/bin/rake:19

任何解决方案？

Answer 1

rake任务参数必须格式为name=value，并尝试将单个单词用作任务名称。

Answer 2

我发现了问题..

C：\ projects \ Test1＆gt; rake test_rake_task csv_header csv_column

这是试图找出我没有的其他rake任务csv_header。

它正在尝试构建csv_header，以便返回错误。

耙子流产了！不知道如何构建任务'csv_header'

这不是使用Rake任务传递参数的正确方法..

如果我们想传递多个参数，我们可以这样传递它。

C：\ projects \ Test1＆gt; rake test_rake_task MODEL_NAMES = csv_header，csv_column
