Chaching and getting id from url


#1

Hi everybody,

I’ve developed an extension that display a list of
links, taken from a database table, in a page of my site called
links.

By clickking on the title of a link a “singlelink”
page will be opened.

In this page is displayed a description of
the link.

To select the single link I’ ve created a
tag.

This tag pass the “link id” by the URL and another
tag get the id from the URL and select the record from the db
table.

This is the code of my tags:

tag
“links:each:link_to_single” do |tag|
curURL =
request.request_uri
%{#{tag.locals.lnk.site_name}}

end

tag “links:single” do |tag|
content =
‘’
curId =
request.params[‘id’]
lnk = Link.find_by_id
curId
tag.locals.lnk = lnk

content << tag.expand
content

end

With this tags I form url like: /en/singlelink?id=2

It works
very well, but now I’ve got problems with the cache. I’ve read some
documents
about Rails Caching and I’ve learned that I must form url like this:
/en/singlelink/2.

I’ve tryed to add in the file “extension.rb” a
map.connect like this:

map.comnect

‘en/singlelink/:id’
:controller =>
‘links’
:requirements => { :id =>
/\d+/},
:page => nil

and
change the tag in this way:

tag “links:each:link_to_single” do
|tag|
curURL = request.request_uri
%{#{tag.locals.lnk.site_name}}

end

But it doesn’t work.

Is there someone who can explain me how
can I solve my caching problems?<!–

Hi everybody,

I’ve developed an extension that display a list of links taken from a
database table in a page of my site called links.

By clicking on the title of a link a “singlelink” page will be opened.

In this page is displayed a description of the link.
To select the single link I’ve created two tags.

This tag pass the “link id” by the URL and another tag get the id from
the URL and select the record from the db table.

content = ‘’
curId = request.params[‘id’]
lnk = Link.find_by_id curId
tag.locals.lnk = lnk
content << tag.expand
content
end

With these tags I form an url like: /en/singlelink?id=2

It works well, but now I’ve got problems with the cache. I’ve read some

Thanks everybody.
