<%=f.text_area :content, :class => 'grow'
I want the class to be conditional to be either "grow" or "nogrow"
I tried
<%=f.text_area :content, :class => grow ? "comment_content grow" : "nogrow"
but that errors. any ideas?
It's all about String Interpolation. Try This...
<%=f.text_area :content, :class => "#{grow ? 'comment_content grow' : 'nogrow'}" %>
:class => grow ? "comment_content grow" : "nogrow"
:class => grow ? "comment_content grow" : "nogrow"
works just fine for me, you just need to end the line with %>
. I suppose you could add some brackets - :class => (grow ? "comment_content grow" : "nogrow")
, better for readability anyway.
