Checking cookies

Rails
1

Hi,
may be a fairly redundant question, as i realize this is not much of a
problem as it is lack of knowledge and capability to find some useful
information on the net;

setting a cookie is easy enough, as i did:

cookies[“survey_#{@survey.id}”] = {:value => ‘abc’}

which works fine, as i checked my browser, and it saved it perfectly.
i was wondering how i check if the user has that cookie or not.
say, in the rhtml i want to block some code if the user has this cookie,
namely:

<% if cookie[“survey_#{@survey.id}”] -%>
…you can’t reach this, you already did the survey…
<% else -%>
…blockofcode
<% end -%>

but unfortunately the cookie[…] doesn’t work. how do i check if a user
has a cookie set in his browser or not?
many thanks for an answer or a lead;

thx,

That should be

cookies[…]

Note the ‘s’.

Actually, that’s not the main problem. The main problem is that the
‘cookies’ method isn’t accessible from views. You can only access it
from your controller.

So in your controller, write something like:

@completed = cookies[“survey_#{@survey.id}”]

And then in your view you can do

<% if @completed -%>
