Boolean Question

[VannSystems]

I have several boolean types and I would like them to show up saying 'yes' or 'no' in view mode instead of 'true' or 'false'

Does anyone know how to do this?

Thanks,
Matt

You could do it a number of ways. Simple, straightforward way is to just do some variant of an if/else:

<% if your_boolean_value %>
  Yes.
<% else %>
  No.
<% end %>

Albeit it's a bit lengthy and can muddle up your views. In any language I'm a fan of the ternary:

<%= your_boolean_value ? "Yes" : "No" %>

You could also do it a number of other ways- via some conditionals in your SQL to return yes/no, via virtual attributes in your model file so you could write something like Model.boolean_word_display or something similar, or so on. Plenty of options to explore.

you can use a helper

def boolean_to_meaning(value)
    case value
      when true : "yes"
      when false : "no"
    end
  end

So every time you need to convert boolean to yes/no you have just to call it

Or like this:

class TrueClass
  def in_english
    "yes"
  end
end
 
class FalseClass
  def in_english
    "no"
  end
end

Thanks... I will give these a try

Or like this:

class TrueClass
  def in_english
    "yes"
  end
end
 
class FalseClass
  def in_english
    "no"
  end
end

I have to say, I don't really like this at all. Surely True in english is just "True"?

I'd go with the helper method posted earlier. Don't get into the habit of reopening core classes just to provide view transformations.

Thanks, I was actually planning on using the helper because that solution confused me a bit
