6. Document help

1) fastri: Are you still using ri to query documents? Then you will surely complain that ri is too slow. It doesn't matter. Open the command window:
Gem install fastri
Follow the quick ri gem package, and then
Fastri-server-B
Create an index and then use qri to query documents. Is the speed n times faster?

2) view this website in a dictionary of rails documents:

7. Debugger

Although ruby is a dynamic language, the debugger function is not inferior to Java. Open the command window:
Gem install ruby-debug-ide-y

Then open your netbeans, open the debugger, and start the rails project in debug mode. Haha, as powerful as Eclipse, you can track stacks, watch variables, and perform one-step operations at breakpoints:

8. Test Coverage Rate

Do you want to know the test coverage rate of the project? Open the command window:
Gem install rcov
Configure rake tasks and run the task to obtain the test coverage rate of the entire project?
