Hey there list-
I am having problems with some @params. I have a route thats
setup like this:
map.connect ''page/display/:storyid'',
:controller => ''page'',
:action => ''display''
So when I hit an url like this:
http://localhost:3000/page/display/299057304776318
I get this in my development log:
Processing PageController#display (for 127.0.0.1 at Wed Jun 15
15:34:09 PDT 2005)
Parameters: {"action"=>"display",
"controller"=>"page",
"storyid"=>"299057304776318"}
Rendering page/display within layouts/page
Rendering layouts/page (200 OK)
Completed in 0.85494 (1 reqs/sec) | Rendering: 0.85179 (99%)
But I try to assign the storyid that should be in the @params like this:
class PageController < ApplicationController
def display
@test = @params[:storyid]
end
end
and then in my display.rhtml
<%= debug(@test) %>
Shows up on the page empty like there is nothing in the @params
[:storyid]. I am using the :storyid to do a net/http fetch of some
content from another webserver and I am having major trouble getting
this to work. It looks like it should be fine. You can see
the :storyid is assigned the correct number in the dev log butr I
can''t seem to access it or I am missing something obvious. Can anyone
shed some light? Is there some other way to access the :storyid from
the @params hash in my controller that I am missing?
Thanks-

There seems to be confusion as to where symbols vs strings should be used. I was bitten by that myself several times. Hope that helps, François

I was bitten by that myself several times.There should be no biting, since with the @params hash (which is actually a HashWithIndifferentAccess) evaluates symbols and strings to the same key, if I''m not mistaken. Likewise, since params is attr''d, you can drop the @, too.
I''m still trying to wrap my head around symbols versus strings. Is there any documentation as to which should be used and where? And how does it work under the hood? - Ben On Jun 16, 2005, at 2:42 PM, Michael Campbell wrote:> On 6/16/05, François Beausoleil <fbeausoleil-IQIa899fVSs@public.gmane.org> wrote: >> >> Ezra Zygmuntowicz said the following on 2005-06-15 18:41: >>> But I try to assign the storyid that should be in the @params like >>> this: >>> >>> class PageController < ApplicationController >>> def display >>> @test = @params[:storyid] >>> end >>> end >> >> Might want to try @params[''storyid''] ? >> >> There seems to be confusion as to where symbols vs strings should be >> used.

Hi, Look in the archives for the "Symbols Help" thread. There the concepts of the symbols are explained. Flurin Ben Jackson wrote:> I''m still trying to wrap my head around symbols versus strings.

Check if it indeed IS in the params first. Second, mind the following - Rails uses the path way (/app/controller/show/4) when you use :id for your parameter name and a query (/app/controller/show?item=5&foo=8) if you use other parameters. Most likely @params[:storyid] will never get set unless you just POSTed to the page with this parameter or sent a query that contains ? blabla&storyid=4. The last component of the path (/show/4) will always be @params[:id] on the controller side. -- Julian "Julik" Tarkhanov
