Issues with rails resourceful routes

Rails
1

I’m not sure where my issue is - if it’s in my routes file (maybe I need
to be more specific) or if it’s the format of the URL.

I am working on a screen scraping project just for fun. It is designed
where the URL of the page you are on is passed into the Rails app, so if
you are on
Rails Routing from the Outside In — Ruby on Rails Guides
and click the button for my app, it routes to
http://localhost:3000/pages/http%3A%2F%2Fguides.rubyonrails.org%2Frouting.html

My routes file has this:

resources :pages

The problem I face is it works for part of the URL. So if I do:

http://localhost:3000/pages/http%3A%2F%2F or
http://localhost:3000/pages/http%3A%2F%2Fguides or
http://localhost:3000/pages/http%3A%2F%2Fguides.rubyonrails

it works. But as soon as I add in the second ‘.’, I start getting
errors.

http://localhost:3000/pages/http%3A%2F%2Fguides.rubyonrails.org

gives me:

Routing Error
No route matches [GET] “/pages/http%3A%2F%2Fguides.rubyonrails.org”

Any ideas?

Maybe I’m just not getting this, but why wouldn’t you pass the URL as
a query string?

Fairly new to rails so that is a good question :slight_smile:

How would I do that?

/pages?url=http://…

/pages/url=http://…

Would I need to change the routes any?

get “/pages/:page” => “controller#page”, value: /./
Notice the "value: /./".

Jordan’s answer notwithstanding,

/pages?url=http://…

This is the format that will give you a query string.

/pages/url=http://…

This form would need to be handled in routes in a manner similar to
the answer Jordan gave.

I tried that and it didn’t work. I understand what it’s trying to do so
I’ll keep playing with it to get it working. I did use the url param
method you have below and that is working.

On a side note - is either one considered to be a better way to do it?
Or just two different ways of solving the same problem? Is there a
length limit to URL params that I might run into?
