rake任务问题

Question

运行带参数的rake任务时出现此问题。

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/bin/rake:19:in `load' 
c:/ruby/bin/rake:19 

任何解决方案？

Answer 1

我发现了问题..

C：\项目\ Test1的>耙test_rake_task csv_header csv_column

这是试图找出我没有它的其他rake任务csv_header。

它试图构建csv_header，所以它返回错误。

rake中止！ 不知道如何建设任务“csv_header”

这是不通过与Rake任务参数的正确方法..

如果我们想要传递我们可以通过这种方式多参数。

C：\项目\ Test1的>耙test_rake_task MODEL_NAMES = csv_header，csv_column

Answer 2

rake任务参数必须格式化为name=value，并且它试图将单个单词用作任务名称。
