Question

In rails, I am trying to get a URL from a model into my javascript in the view as a string. This is what I do currently.

#in the model
has_attached_file :avatar, styles: { thumb: "60x60>"}, :default_url => "/system/users/avatars/thumb/missing.png"
#using paperclip gem.
....
def someMethod
   return [neares.map{|u| u.avatar.url(:thumb)}.compact]
end

Later in the view I do the following:

anArray = <%=aModelInstace.someMethod().to_json%>;

This is what I get in my rendered javascript:

//swap all the $ with &
anArray = [[$quot;/system/users/avatars/thumb/missing.png$quot;],[/* many similar to the previous */]];

This does not compile and causes an error, “unexpected token &”. So how can I get this to return an actual string in javascript, and not just with the wrapped quot signs?

I have tried u.avatar.url(:thumb).to_s and "#{u.avatar.url(:thumb)}". No luck. Also, hours of googling got me nowhere 🙁

As apneadiving and Benjamin Tan said:

Use:

anArray = <%=raw aModelInstace.someMethod().to_json%>;

This solved the problem.
