Runy-on-rails – the command output in the Rails console: No description of the output?

Model.find(:all ).each do |x| p x.name end

Model.find(:all).map{ |x| x.name }< /pre> 
Or prevent the output and return something like nil:
 
 
Model.find(:all).each{ |x| p x.name }; nil 

I am using rails console and some models. I am running something:

Model. find(:all).each do |x| p x.name end

This is fine, it allows me to see all the values ​​of a specific column, but after printing out these lines, it prints Out the entire model.

Why do you do this? How can I stop it?

The console always prints the return value of the command. And the return value of .each is the initial array.

So you either Return the value you need:

Model.find(:all).map{ |x| x.name }

Or prevent the output, return something like nil stuff:

Model.find(:all).each{ |x| p x.name }; nil
