Redirecting old URLs to new permalinked URLs

rubyonrails-talk
1

Im currently in the process of adding permalinking to my site; at the moment I am simply testing it out in development mode.

The problem is that at the moment I have all of these URLs that lead to the same content:

http://127.0.0.1:3000/categories/1-css/tutorials/12-test9 http://127.0.0.1:3000/tutorials/12-test9 http://127.0.0.1:3000/categories/1/tutorials/12 http://127.0.0.1:3000/tutorials/12

What I'm trying to acheive is to get all of these URLs to redirect to the top one so that google won't think I've got duplicate content.

Please Help,

If you need any more information feel free to ask,

Thanks In Advance,

-Joe

Bump?! Can anyone help with this?

Try gem rack-rewrite, that can solve your problem.

I see code like this used in examples:

config.gem 'rack-rewrite', '~> 1.0.0'   require 'rack/rewrite'   config.middleware.insert_before(Rack::Lock, Rack::Rewrite) do     rewrite '/wiki/John_Trupiano', '/john'     r301 '/wiki/Yair_Flicker', '/yair'     r302 '/wiki/Greg_Jastrab', '/greg'     r301 %r{/wiki/(\w+)_\w+}, '/$1'   end

Where does this code go?

How can I make this apply to a whole group? For example instead of only making tutorials/61 go to the proper URL, making anything that is just "/tutorials/SOMETHING" go to the proper URL?

Please Help,

Thanks In Advance,

Hi Joe,

Firstly, this code goes in config/application.rb. Secondly, you can write regular expression like the example did to redirect your URLs.

More problems..

Firstly I don't have an application.rb file to add this into.

Secondly, where does my example use a regular expression? and how can I do something similar with my RoR application?

Bump?! Please help.

Where does this code go?

Look at your app and see where you find 'config.gem' entries. Or read about using Rack middleware. It should be pretty obvious :slight_smile:

How can I make this apply to a whole group?

And you've already gotten that answer -- use a regular expression. If you don't recognize that your own example includes one, you're probably in deep bandini already :slight_smile:

Good luck,

The environment files?

I think thats where it would go. As for regular expressions, I don't have a clue where it is in the example, Im really not amazingly good in RoR and I would very much appreciate some help with figuring it out..

So try it and see :slight_smile:

What programming language *do* you know? Because if this line:

    r301 %r{/wiki/(\w+)_\w+}, '/$1'

:: doesn't jump out at you as a regular expression -- certainly when contrasted with the other example lines -- then I suspect you need to just plain read up on RegEx in general...

I program in many languages, and that does not stand out to me. I know C++, Java, CSS, HTML, Lua, and Visual Basic; and that doesn't stand out to me. I assume that this is from a whole different category of programming/scripting languages; of which I don't know.

Could you please explain to me how it works, and how I can use it in my personal scenario?

Thanks In Advance,

Joe

CSS and HTML aren't programming languages. C++ and Java don't have much regex support. I don't know Lua or VB, so can't comment.

To some extent.

That would be a bit of a waste of time until you go read the Pickaxe Book's explanation of regular expressions. You've asked a huge number of elementary questions here that could have been answered by reading the docs.

Thanks In Advance,

Joe

Best,

15

I think you need to just learn something about regular expressions.

   /wiki/(\w+)_\w+

"\w A word character: [a-zA-Z_0-9]"

The above definition is taken from the API doc for `java.util.regex` :slight_smile: which also uses the same '+' quantifier and '( )' capture group syntax.

So there's nothing out of the ordinary here that a little regex study shouldn't serve to enlighten...

16

Hmm. Ok. Ill look into it.

So I guess ill want something like this: r301 %r{/tutorials/(\w+)}, '/ $1' But instead of using the first unknown word variable (as "/$1" would refer to (as far as I know)); I want it to go to my permalinked URL (http://127.0.0.1:3000/categories/1-css/tutorials/12-test9 ).

Please Help (Meanwhile ill look up some regex),

Thanks In Advance,

Joe

17

Why guess? That's what docs are for --

<http://github.com/jtrupiano/rack-rewrite/blob/master/README.rdoc&gt;

There's this thing called 'Der Google', see... :slight_smile:

18

I've already read this, and still don't understand.

Would I need something like this?

rewrite %r{/tutorials/(\w+)categories/(\w+)}, '/categories/ CategoryPermalinkHere/tutorials/TutorialPermalinkHere' rewrite %r{/tutorials/(\w+)}, '/categories/CategoryPermalinkHere/ tutorials/TutorialPermalinkHere'

Please Help,

I've looked everywhere but just can't figure it out.

Thanks In Advance,

As I said, it's using regular expressions, and *you* need to figure out how they work. Find a regex tutorial, open up irb and play around.

Then, or even before, use the examples in the Rack::Rewrite docs to experiment. It'll take less time to *just try it* than to compose an email. And at least you'll be able to say "here's what I want, here's what I've tried, here are the results".

FWIW,

I've tried, but I can't figure out how to replace $1 with a permalink variable thats in ruby on rails. Im pretty sure regex cannot help me with this, I need to take the permalink value, and use that in the redirect.

PLEASE JUST TELL ME AND ILL LEARN, I DONT JUST TAKE THE ANSWER AND BE DONE WITH IT, I LEARN FROM IT.

Please Help,

Thanks In Advnce,
