An error I can't find

ruby-talk

Hello, there's certainly a monstrous error I don't see in :
<% for i in @news %>
  <% if dern_cat != i.categorie %>
   <% case i.categorie %>
   <% end %>
  <% end %>
<% end %>

I've removed all the code I could and don't understand why the case i.categorie produce a syntax error, unexpected tIDENTIFIER, expecting kWHEN

What is that syntax error ?

Thank you

This is just what I found, maybe it'll help:
   
  http://www.ruby-doc.org/docs/UsersGuide/rg/control.html
   
  l- ooking at their example it seems the syntax should be:
  case
    when
  end
   
  I guess that's why it's saying it's expecting "when".

The correct Syntax would be something like this (not tested):
<% for i in @news %>
  <% if dern_cat != i.categorie %>
   <% case i.categorie %>
     <% when bar then foo %>
   <% end %>
  <% end %>
<% end %>

I removed the 'when' statements just to have the shortest source code...
with

when 'foo'
   doit()
when 'bar'
   dont()

the error is the same

that's the correct synthax, working with me without problems:

for i in @news do
  if dern_cat != i.categorie then

   case i.categorie
    when bar :foo
   end

  end
end

If you still have problems post your whole code and the exact and whole errormessage you are getting!

Dear Zouplaz,

it seems you opened a case-end statement and incorporated
when-end statements into it.
But the when part doesn't end in 'end', but in the next when
statement:

  case condition

    when 1

      puts "First thing."

    when 2

      puts "Second thing."

  else

      puts 'you didn\'t satisfy the condition!!!!'
  end

Best regards,

Axel
