Ruby/Sinatra - Variable inside erb calls

[Scott Elwood]

Hi there,

I have a question regarding variables inside of erb arguments. This is
what I would like to achieve:




require 'sinatra'

get '/' do
style = 'default'
erb :'templates/'+style+'/layout'
end




Running that will give you errors, saying there can't be a plus sign for
the concatenation.

Is there a way to work around this?

(drop ':' operator, it is not necessary).

According to the Sinatra docs, it must be a symbol.

So I would just use string interpolation:

erb :"templates/#{style}/layout"

Thank you both for the help, it works perfectly and I now understand why
it wasn't working before
