ruby on rails - using @college.name inside of an image_tag -

i'm using rails 3.2.13.

i have @college.name variable available me in view file. have carousel of pictures (3 per school). names of jpg files in form of university_of_pittsburgh1.jpg, university_of_pittsburgh2.jpg, , university_of_pittsburgh3.jpg. i'd link them doing

<%= image_tag "@college.name1.jpg" %>

but doesn't seem working. how link pictures properly?

<%= image_tag "#{@college.name}1.jpg" %> 

you want use string interpolation wrapping @college.name in set of braces: #{...}

this replace actual college name, while 1.jpg part outside of braces added on. above interpreted as:

<%= image_tag "university_of_pittsburgh1.jpg" %>
