HAML error using ternary operator in a mailer response

[Matt Martini]

I'm getting a HAML error when I try to use the ternary operator in a mailer response.

I have a mailer notifier that returns a form submission via email.  I want to pretty up the output so that 

the response of the radio_button :erected (which returns true or false) would be 'yes' or 'no,' respectively.

Using: 

    = ( #{@qmessage.erected} == true ) ? 'Yes' : 'No'

produces the error below.  I also tried it with "-" instead of "=".

I suspect this might be a bug as I don't have any semi-colons in my haml and yet the error message complains about an unexpected one.

Please let me know if my syntax is wrong or this is a bug.

I think this should be:

= @qmessage.erected == true ? 'Yes' : 'No'

I'm not sure why you're using the string interpolation #{} here.

Anoop,

= @qmessage.erected == true ? 'Yes' : 'No'

doesn't throw an error, but it does not return the correct response.

Yes is checked on the submitted form:

HAML:

      .field

        #{@qmessage.erected}

        %br

        @qmessage.erected

        %br

        = #{@qmessage.erected} == true ? 'Yes' : 'No'

        %br

        = @qmessage.erected == true ? 'Yes' : 'No'

Returned in email:

true 
@qmessage.erected 

No

So if I don't use string interpolation, I get back "@qmessage.erected". 

= #{@qmessage.erected} == true ? 'Yes' : 'No'

returns nothing

= (#{@qmessage.erected} == true) ? 'Yes' : 'No'

returns the error below.

I still think this might be a bug as why should adding parens throw an error?
