Turning URL varables into URLs

rubyonrails-talk
1

OK, so I have a homepage and want the user to be able to select a link that goes back to it with a varable set. Example here is the listings site lists all events regardless of price and I want users to be able to list events under £5. So I have a link https://eventpuddle.com?price=cheap. This is fine but for SEO reasons I want to have the URL something like https://eventpuddle.com/cheapevents. Obviesly I could create another view but there are all sorts of things I will ultimatly want ot do this for. https://eventpuddle.com/jazz, https://eventpuddle.com/pucn, https://eventpuddle.com/art… i would end up with LOTS of views and have to do code changes for eatch (see below). I came across something years ago (I think in PHP) where URLs got unpacked into varables in the background. So https://eventpuddle.com/**price**/**cheapevents** was mapped in the background and created a varable price with a value cheapevents.

This will also be usefull for listing events for a certain venue, whitch I have lots. Dont want to create a view for eatch venue as there are lots and I dont want to have to code stuff if I add venues, I simply add a row in the database for the new venue. The kind of URLs I would be looking for is https://eventpuddle.com/venue/old-market-assembly or https://eventpuddle.com/venue/canteen.

Wondering if there is a way of doing this in rails or another way of handeling the same type of thing.

Great, thanks, almost there. Mine is slightly different as its not based on CRUD, its a ruby view based on a SQL view. So

get ``'/patients/:id'``, to: ``'patients#show'

Is not quite what I need. If I have this view as root view (http://domain.tld) and want to pass cost as a variable (http://domain.tld?cost=cheapevents = http://domain.tld/cheapevents). Its the site root

currently I have

root 'upcoming_events#index'
**get** 'upcoming_events/index'



I tried


**get** 'upcoming_events/index:cost', to: 'upcoming_events#index'


And it works for root but if I try **http://domain.tld/cheapevents** I get

No route matches [GET] “/cheapevents”

PS I also tried

get 'upcoming_events/cost', to: 'upcoming_events#index'

Aslo http://localhost:3000/upcoming_events/cost works but not http://localhost:3000/upcoming_events/cost/cheapevents.

Irrelevant. You can use any parameter and controller method names you choose.

You can use something like this

get ‘venue/:name:’, to: ‘venues#show’

class VenueController

def show

render the view by checking params[:name]

end

end

Check the above linked routing guide for more details

You can try something like this if the requirements match:

  match "/*path", to: redirect { |params, request|

I don’t know why you’re still trying /cheapevents when you haven’t defined it at all.

Not best practices really, but try something like:

get ‘events/:cost’, to: ‘upcoming_events#index’

and then in your controller, respond based on things like:

if params[:cost] == “cheap”

@events = Events.where(“price < 5”)

end

So you can then navigate to url.name/events/cheap
