Dynamic mapping in controller

Rails
1

Hi,

I have used scaffold to create my rails project and hence I have a
database containing a table called “results” and when i call the “show”
action followed by the ID it brings up a list of the relative record and
its details.

What I want though is for if someone types in say
localhost/results/etab-mobile that it maps dynamically to
localhost/show/1 but keeps localhost/etab-mobile in the address bar. the
“etab-mobile” title is found in the database under “module_name” so can
be pulled out for use.

I know this can be done in the routes.rb folder statically but would
like to do it in the controller so that its not as static.

is this possible?

thanks,

Chris

Hi,

I think its possible only thru routes.rb, cannot be done in controller,
As i see, if you have “link_name” in your database for each page on
site:
like:
http://site.com/homepage → redirects to /site/1
http://site.com/about → /site/3
in table of “menus” its looks
id — link ----------- name — …
1 homepage Welcome to Homepage
3 about Everything about us

“link” field is used to be a “friendly” link and generated thru
routes.rb.
i think is simpliest way.

look at http://eurobdc.com at their links.

that sounds like the way id like to do it but im having trouble getting
my head around how to code it:

at the moment i have

map.connect ‘etab-mobile’,
:controller => ‘results’,
:action => ‘show’,
:id => ‘1’

but id like that :id =>‘1’ to be loaded in from my database rather than
statically as I have other results that id like to show with id =2 and
id=3 and so on…

You cannot display dynamic results under the same route showing in the
address bar, except you use POST instead of GET

Maybe that would work … someone would type :
http://yoursite.com/results/etab-mobile
and the route would be:
map.connect ‘results/:module_name’,
:controller => ‘results’,
:action => ‘show’

then you have params[:module_name] available in your show action and
can pull the correct dataset from the DB
with find(:first, :conditions => [module_name =
?,params[:module_name]])
or sth. similar.
