Example:
You know the site about.com ?
They have a whole subset of url's such as: pottery.about.com
My question: How to get the "pottery" in front of the URL?
Anybody have some nifty mod_rewrite to do this?
Thanks!
David
Those are considered sub domains, you can set them up most of the time through any hosting company. Usually they dont charge you for them, but some do. They are very easy to setup and can be done quickly versus regular domain names.

I would like create web app like shopify.com.
User can pickup subdomain(or domain), theme and have own store.
How can I do this?
Create main application, deploy it automatically like new standalone version and update it via git?
I'm using Rails 3.
Thanks for your advice.
Based on replies:
When I choose to use only one application (without multiple instances) and give user his subdomain, it will looks like their own website. But everything will be in one database (It's good idea?). And how can I have multiple themes in Rails app?
Take a look at LocomotiveCMS, specifically the routing system. Locomotive actually hosts multiple sites inside a single rails application. It does this by inspecting the request URL when it comes in and setting the current_site variable with the site which is set up to handle the domain. Then the current_site is actually just an object which contains all the pages, contents, settings, etc. for the specific site being served up.
So to answer your question, I think a good solution is to give your rails app the ability to serve up multiple sites based on the domain. It's not that hard, and it seems less fragile to me than trying to automatically deploy new instances of an app.
So far I have understood, you want to let your users have their own subdomain, different theme but the functionality would be same right. Users just need to have a feel of something of their own.
Well definitely, you need to have a single application that supports multiple subdomains.
A quick googling gave me [ http://37signals.com/svn/posts/1512-how-to-do-basecamp-style-subdomains-in-rails ]. May be you can get some insights from here.
For example if your service is http://www.myfi.com, a brief idea can be:
When a customer is registering, you should let him choose his subdomain. And the newly created account will be associated with this subdomain with a url. Say, http://customer1.myfi.com.
You should register for domain *.myfi.com so that anyone in the world hit with anysubdomain.myfi.com, it comes in your application.
Then from the url part, you should identify the subdomain (customer1) that is being used, and need to set that in session.
Now when someone will try to login, you must verify the account in the context of that subdomain's account.
In fact, all following actions need to be handled in the context of the subdomain's account.
Just tried the gather a glimpse of the implementation here. If you have confusion about something specific, share that also.
Edit:
Whenever you are thinking about multiple theme, you must have simple design which is completely driven by css and js. The app/view files should contain only content and HTML nodes with class names or ids.
Generally a UI designer can put more helpful ideas about how to make such theming mechanism. But all I can feel is, based on the chosen theme by customer, you have to load different css and js.
Actually the strategies can be indefinitely sophisticated and scalable, but its always wise to start with something easy. Then ideas will automatically evolve into better ones.
I'm creating a rails app where users will be able to create and manage multiple blogs from their accounts. The app will be hosted on www.mydomain.com but i want users to specify a domain they own and be able to point it to any of the blogs they've created so that they can have www.usersite.com point to www.mydomain.com/user/:user_id/blog/:blog_id
that way it looks like is being hosted on their site even though is not
i've been reading some post and maybe CNAME is the way to go for this, but i'm pretty new to creating rails apps and if anyone can help me or point me in the right direction i would appriciate it.
If you need me to clarify anything please let me know
Thanks in advace

As far as I understood your question is more about DNS rather than Rails.
I could suggest you Bandcamp as a live example.
There's some tips:
Using CNAME (and I pretty much sure there's no other options) You should provide every user with his own unique subdomain i.e. user.mydomain.com in your case. Quick googling and we find out that there's a solution for Rails 3 — http://bcardarella.com/post/716951242/custom-subdomains-in-rails-3
You should provide them with step-by-step manual how exactly they can modify their domain DNS entries and add CNAME record. It's up to them. You or Your app can't do it. Again, Bandcamp is a great example — http://bandcamp.com/faq_custom_domains
And then you win.
I am looking at implementing URLMapping for a personal project. I am already aware that solutions exist so please do not answer suggesting I should use one.
What I want is to harvest the opinions of fellow developers and web users on URL mapping implementations. Specially I would like you to answer:
Which is your favourite implementation?
What do you like about your favourite implementation?
What do you not like about your favourite implementation?
How would you improve it?
I would like you to answer from two points of view:
As a developer
As a user
I would be grateful for any opinions on this matter, thanks!
I've only worked with django's URLConf mechanism. I think the way it relies on the urlpatterns variable is a bit flimsy, but I like its expressiveness in specifying patterns and dispatching to other url configurations. I think probably the best thing is to figure out your URL scheme first, and then try out a couple of solutions to see what matches best. If you're going hard-core REST using the full complement of GET/POST/PUT/DELETE, and checking the user agent's Accept headers, and all that, django will, by default, have you splitting your logic between URL config files and view files, so it might not be the cleanest solution.
However, since it's all Python, you might be able to do some more complex processing before you assign to urlpatterns.
Really, you want a system that does what you need. Your URL scheme is your API, so don't compromise on it based on the tools you use. Figure out your API, then find the tools that will let you do that and get out of your way.
Edit: Also do a google search for "URL scheme design." I found this without much effort: http://www.gaffneyware.com/urldesign.htm. Not comprehensive, but some good advice gotten from looking at what flickr does.
Well, I should have noticed the url-routing tag shouldn't I? :-) Sorry about that.
jcd's experience mimics mine - Django is what I use too.
I like the fact that the routes for an app reside within the app (in urls.py) and can just be included into any projects that might make use of that app. I am comfortable with regular expressions, so having the routes be specified in regex doesn't phase me (but I've seen other programmers scratch their heads at some more uncommon expressions).
Being able to reverse a route via some identifier (in Django's case by route's name) is a must. Hardcoding urls in templates or controllers (view in Django) is a big no-no. Django has a template tag that uses the reverse() method
The one thing I wish I could do is have the concept of default routes in django (like Rails does or even Pylons). In Django every route has to map to a view method, there is no concept of trying to call a certain view based on the URL itself. The benefit is that there are no surprises - your urls.py is the Table of Contents for your project or app. The disadvantage is that urls.py tend to be longer.
This is rather difficult to explain so please bear with me.
We will be hosting 4 websites on our server and the plan is to have each site sit under its own domain:
site-a.com
site-b.com
sub1.site-b.com
sub2.site-b.com
Notice the two sub domains!
However, our client has asked if we can implement the following url structure instead of using subdomains:
sub1.site-b.com BECOMES site-b.com/sub1/
sub2.site-b.com BECOMES site-b.com/sub2/
Does this make sense so far??? So we are using forward slash as opposed to sub domains.
Can you advise on the best way to achieve this please?
Thanks for any help!
Dave.
Use Apache to remap the domains. It's probably your webserver, so it's probably the answer.
The docs are here:
http://httpd.apache.org/docs/1.3/mod/mod_alias.html#redirect
Match your subdomain and redirect to the appropriate folder, copying and carrying over the query string as appropriate.
JQuery probably won't help you.
This will depend on your hosting situation.
In IIS you can setup virtual directories for this type of behaviour.
You could also use JavaScript or server side redirects in sub1, sub2 etc folders.
I'm a student of web development (and college), so my apologies if this comes off sounding naive and offensive, I certainly don't mean it that way. My experience has been with PHP and with a smallish project on the horizon (a glorified shift calendar) I hoped to learn one of the higher level frameworks to ease the code burden. So far, I looked at CakePHP Symfony Django and Rails.
With PHP, the URLs mapped very simply to the files, and it "just worked". It was quick for the server, and intuitive. But with all of these frameworks, there is this inclination to "pretty up" the URLs by making them map to different functions and route the parameters to different variables in different files.
"The Rails Way" book that I'm reading admits that this is dog slow and is the cause of most performance pains on largish projects. My question is "why have it in the first place?"? Is there a specific point in the url-maps-to-a-file paradigm (or mod_rewrite to a single file) that necessitates regexes and complicated routing schemes? Am I missing out on something by not using them?
Thanks in advance!
URLs should be easy to remember and say. And the user should know what to expect when she see that URL. Mapping URL directly to file doesn't always allow that.
You might want to use diffrent URLs for the same, or at least similar, information displayed. If your server forces you to use 1 url <-> 1 file mapping, you need to create additional files with all their function being to redirect to other file. Or you use stuff like mod_rewrite which isn't easier then Rails' url mappings.
In one of my applications I use URL that looks like http://www.example.com/username/some additional stuff/. This can be also made with mod_rewrite, but at least for me it's easier to configure urls in django project then in every apache instance I run application at.
just my 2 cents...
Most of it has already been covered, but nobody has mentioned SEO yet. Google puts alot of weight on the URL itself, if that url is widgets.com/browse.php?17, that is not very SEO friendly. If your URL is widgets.com/products/buttons/ that will have a positive impact on your page rank for buttons
Storing application code in the document tree of the web server is a security concern.
a misconfiguration might accidentally reveal source code to visitors
files injected through a security vulnerability are immediately executable by HTTP requests
backup files (created e.g. by text editors) may reveal code or be executable in case of misconfiguration
old files which the administrator has failed to delete can reveal unintended functionality
requests to library files must be explicitly denied
URLs reveal implementation details (which language/framework was used)
Note that all of the above are not a problem as long as other things don't go wrong (and some of these mistakes would be serious even alone). But something always goes wrong, and extra lines of defense are good to have.
Django URLs are also very customizable. With PHP frameworks like Code Igniter (I'm not sure about Rails) your forced into the /class/method/extra/ URL structure. While this may be good for small projects and apps, as soon as you try and make it larger/more dynamic you run into problems and have to rewrite some of the framework code to handle it.
Also, routers are like mod_rewrite, but much more flexible. They are not regular expression-bound, and thus, have more options for different types of routes.
Depends on how big your application is. We've got a fairly large app (50+ models) and it isn't causing us any problems. When it does, we'll worry about it then.
