Using helper methods like html_escape in rails console

Question

I am trying to see what is going wrong with my encoding of variables in my view. So I fire up rails console and try to do

$ rails console
Loading development environment (Rails 3.2.11)
irb(main):001:0> html_escape({:a=>1, :b=>"my str"})
NoMethodError: undefined method `html_escape' for main:Object

How do I use h or html_escape in rails console?

Easy to solve. html_escape is defined in ERB::Util so simply write:

include ERB::Util

in your console prior to the first use of html_escape

any idea what the html_escape helper method does? (noob trying to learn.) – BenKoshy Sep 14 '15 at 21:30

you call it through helper. some methods are private so you may need to use send to call them

helper.send(:html_escape, '123')
helper.pluralize 3, 'user'

> helper.send(:html_escape, '{ a: 1, b: "my str" }')
"{ a: 1, b: &quot;my str&quot; }"

you should check the answers as well, if something is already answered, then you do not need to write the same answer again. – Manoj Monga Mar 01 '13 at 17:59
