Question

I am using Intype:

I have a problem with this:

def convert_html_entities(text)
    text = text.gsub(/["]/, '"')   
end 

The Intype colors it all green because there is missing a “

I have tried this solution it removed all the green text and the code appeared normal:

def convert_html_entities(text)
    text = text.gsub(/['"']/, '"') 
end 

But it just gave an error in view:

undefined method `convert_html_entities' for #<XmlController:0x448cef0>

Answer 1

Apparently you did not define convert_html_entities as an instance method of XmlController, so you can’t use it as one.

Another problem with your code is that reassigning a method parameter, doesn’t have any effect on the outside. So text = text.gsub(/['"']/, '"') is the same as text.gsub(/['"']/, '"'). If you want to mutate your argument, you need to use gsub!. That being said: Don’t mutate method arguments. That’s bad style.
