Another +1 for Pry -- absolutely an essential tool.

Another very good option is to learn to use a debugger (that can help you a
lot until you learn Ruby / Rails better, but it can be useful then as
well), is to have a look at Pry
https://github.com/deivid-rodriguez/pry-byebug or for ruby 1.9.3
https://github.com/nixme/pry-debugger.

You will need maybe 1-2 hours to set it up and learn to use it, but after
that you will get answer to questions like the above in a few seconds or
minutes depending on the problem.

Cheers

As I believe I have suggested to you before, first level simple
debugging can be done using logger.info, so in this case if you insert
before the last line something like

logger.info "Show date: #{@showmonth}, #{@showday}, #{@showyear}"

then you will see in the terminal what values those variables have.

[Rails] no method for nill class

2017-04-20 Thread fugee ohu 
In the snippet below,the last line causes the error; :showdate is 
whitelisted, it's components appear just in the params list returned by the 
browser The error's at the plus sign but not sure which of them

@showday = params["showdate(3i)"]
showmonth_string = params["showdate(2i)"]
@showmonth = Date::MONTHNAMES[showmonth_string.to_i]
@showyear = params["showdate(1i)"]
@showdate = @showmonth + " " + @showday + ", " + @showyear
