Multisite application in Rails (like shopify.com) - ruby-on-rails

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.

Mautik hosting best practice

I am new to Mautik and therefore need a guidance on the same.
Where should we setup mautik... on some folder or on sub domain to main site or a separate domain? How does the landing pages and forms gets its URL? Can it be embedded on another site on another domain or is it required to be hosted where mautik is hosted?
Moreover does single installation of mautik can be used for two or more different businesses site... which are not relevant.. and mainly a different customer for a marketing company? Or is it better to install mautik per business?
Can we track interactions from mobile app too using mautik?
First thing, I expect you are talking about Mautic and not Mautik.
You are free to choose whatever type of hosting you want, personally I Like to use independent container(could be lightweight) however I have seen people hosting on shared hosting as well.
If you are hosting on say example.com the landing page url will be example.com/landing-page same goes for all elements of mautic.
Yes forms can be embedded on other websites with a completely different domain. say example-something-else.com, you will need to put your tracking script on other site's head to make it work better. I for example check out this small tutorial https://tutorialsjoint.com/mautic-wordpress-integration/ it shows how you can use it in wordpress.
No it is not required that wherever you want to use mautic form should be on same host or domain.
However I recommend to use subdomain if usually just to save the hassle of buying a new domain and keeping the landing page urls more relevant. https://www.youtube.com/watch?v=K8lWaCabH1w this video shows how tracking works, it'll help you understand little better. Also here's official documentation: https://docs.mautic.org/en/contacts/manage-contacts/contact-monitoring.
You can use use one instance to manage multiple businesses I know people who are doing it but when the number of contacts, segments, campaigns, form, emails, landing pages grow with time it becomes a hassle to keep it clean. You can use category and a specific naming convention to keep them organized. But in a good way i will recommend to keep different instances in long run.
I am not sure about mobile apps but ideally it should be possible using tracking script or tracking pixel, perhaps you will need to turn off CORS restrictions.
I hope it was helpful.
Cheers!
No, you must use a VPS with Devian or Ubuntu, In a shared hosting it can cause problems. If you send many emails.
Landing pages can be made in html and pasted or edited in Mautic.
To use it in more sites you must create a user for each one, with their respective different email.

Possible to skip website web.config in sub application?

In IIS I want to deploy a sub application in a website. I really don't want to bother with having to update the root website's web.config with location tags all over the place.
Is it possible to direct the sub application to just totally ignore the root website's web.config?
Okay, so that's my question. The following is just additional information that could lead someone to offer an alternate solution I haven't thought of but if possible I hope you won't judge my post on the following since, as I mentioned, the above is my question... this is just extra information for the interested:
I am deploying several websites. Each website will have an admin application which will have the same codebase. I want the admin application to be available at site1.com/admin, site2.com/admin, etc.
In the past I did something similar on another project, but instead of having sub apps I did sub domains to another site... so it would have been like site1.admin.com, site2.admin.com, etc. Nice thing about this solution was the ease of just adding additional bindings for any new site (and the application would look at host name to apply proper theming, configuration, security, etc.). I would have preferred this solution again but it just won't work this time because we can't easily secure a proper domain name for that purpose and aside from that we would prefer the user stay on the same domain name anyway just from a marketing perspective.
So ultimately my goals are:
Have the web address be "sitename.com/admin"
Only deploy the admin application to one location
Avoid spending 2 days trying to figure out how to properly configure everything so that configs don't clash and then still end up with a
few errors I spontaneously find over the course of the next week and
eventually find one that requires me to reprogram a large section of
code in order to play nicely with the root website. (If you can't
tell, I may have minor PTSD from trying something like this a couple
years back).
I mean, what would be really super is if I could have admin be its own web application and have bindings like "site1.com/admin" and "site2.com/admin" but obviously that's not possible. But maybe there are some other straightforward solutions I haven't thought of yet?

Rails Authentication via Web Service

So, this may be a kind of dumb question, but I checked the Google and got no hits. We want to host multiple Rails apps in a way that makes them look homogeneous. We want all the apps to have the same look and feel, and all the apps to use the same sign-on database.
Theming I think we could accomplish by just putting the site theme into a gem, and requiring that gem from our github repository in each app. However, auth is trickier.
I know that I can achieve this "for free" by just not making the different portions of the site (store, chat forums, etc.) different apps. If they're all, say, Rails Engines, we can basically drop them into the same application with their own namespaced routes, and have a single plugin that does auth.
However, for various reasons we'd like to keep these separate apps, if that's technically possible. The number one reason is scalability; since this will be a hosted site, we want the flexibility to spin up more instances of, say, the store (perhaps to handle a holiday sale rush), without needing to spin up the chat forums. Also, we want to be able to completely isolate the portions of the code that AREN'T intertwined.
Ideally, the databases would be separate too (keeping us from falling back into the rut of "put everything including the kitchen sink in the db"), but I do know that one "cheap" way to do cross-app auth is just to use the same plugin (say, Devise), and just point to the same DB.
So, I'm thinking that maybe the way to do this is to auth via a web service call. Is this prior art -- does anyone have a gem for this that "just works" so that authentication can be shared across all apps? Or am I just entering into a world of pain by trying to build things this way?
Thanks in advance!
You could do a single sign on approach described at:
http://blog.joshsoftware.com/2010/12/16/multiple-applications-with-devise-omniauth-and-single-sign-on/
The single sign on approach with oauth and devise has some drawbacks. The main problem I had was I was unable to extend the timeout time across multiple apps.

Multi domain rails app. How to intelligently use MVC?

Background:
We have app a, b, and plan to add more apps into this same application. The apps are similar enough they could share many views, assets, and actions. Currently a,b live in a single rails app(2.3.10). c will be similar enough that it could also be in this rails app.
The problem:
As we continue to add more apps to this one app, there's going to be too much case logic that the app will soon become a nightmare to maintain. There will also be potential namespace issues. However, the apps are very similar in function and layout, it also makes sense to keep them in one app so that it's one app to maintain(since roughly 50% of site look/functionality will be shared).
What we are trying to do is keep this as clean as possible so it's easy for multiple teams to work on and easy to maintain.
Some things we've thought about/are trying:
Engines. Make each app an engine. This would let us base routes on the domain. It also allows us to pull out controllers, models and views for the specific app. This solution does not seem ideal as we won't be reusing the apps any time soon. And explicitly stating the host in the routes doesn't seem right.
Skinning/themes. The auth logic would be different between the apps. Each user model would be different. So it's not just a skinning problem.
In app/view add folder sitea for sitea views, siteb for siteb views and so on. Do the same for controllers and models. This is still pretty messy and since it didn't follow naming conventions, it did not work with rails so nicely and made much of the code messier.
Making another rails app. We just didn't want to maintain the same controller or view in 2 apps if they are identical.
What we want to do is make the app intelligently use a controller based on the host. So there would be a sessions controller for each app, and perhaps some parent session controller for shared logic(not needed now). In each of these session controllers, it handles authentication for that specific app. So if the domain is a.mysite.com, it would use session controller for app a and know to use app a's views,models,controllers. And if the domain is b.mysite, it would use the session controller for b. And there would be a user model for a and user model for b, which also would be determined by the domain.
Does anyone have any suggestions or experience with this situation? And ideally using rails 2.3.x as updating to rails 3 isn't an option right now.
Devise does exactly this. You would do well to check out its architecture and apply that architecture to your own case.
You will have multiple separate Rails applications. The shared code will be a separate project, perhaps distributed as a gem or at least a separate Git repository. The shared code will include many controller actions and many view templates that are there to be sensible defaults, and which will be overridden in some apps but not in others.
All the custom code for application A will belong in a project solely devoted to containing the custom code for application A. It will be its own fully-functioning Rails application and will depend heavily on the majority of the sensible defaults provided by the shared code in the shared-code project.
I've used the theme support plugin before and dynamically set the theme based on the request uri:
http://mattmccray.com/svn/rails/plugins/theme_support
It will probably need some work to support Rails 2.3.
Update: Looks like there's a rewrite: https://github.com/dasil003/rails-multisite
Sounds like you want to make the 'base' app a plugin and use that in each of your site apps. You can use something like svn-extern so it's automatically updated whenever something changes.

How to turn a single-site app into a mantainable multi-site app without code changes?

It's an application that we use internally at the office that I would like to offer as a hosted service for anyone.
How can I do that without making major code changes?
The first thing that occurs to me is to have the app select which database to connect to based on the domain.
So each instance of the app would have its own database, but all instances would share the same code.
The only changes required to the code would be the database selection.
Is this approach maintainable? I've heard wordpress.com does this and that it offers a couple of advantages. I'm mainly looking to do it this way to avoid have to scope my entire set of database queries to a certain site within the same database.
Thanks!
The simplest way to do this is to clone the application, and create another server instance to handle it. This actually the way I handle multiple wordpress blogs on my server
Pro:
This process can be streamlined into a utility script.
Can be easily maintained if symlinks are used for the common code. IE: Everything but branding and some of the things in the config directory.
Cons:
- If you're using passenger it will require an apache restart for each new instance.
- Same if you're using Apache to route subdomains on different virtual hosts to different mongrel clusters.
However the better way comes from the question: Rails - Separate Database Per Subdomain
The method in the accepted answer is much more robust. It might require more changes than you're looking for, but it has all the benefits without the drawbacks of any other methods. Each new instance requires a new entry in the master database with the table name and other instance specific information. You'll also want custom rake task to build the database for each new instance.
I would suggest switching the database connection and adding a view_path based on the domain, I have posted code in this question.
I hope this helps!
I wouldn't do this with multiple databases as you mentioned. Keeping all your schemas/migrations in sync with all the db's could become painful.
I would look into simply making it a multi-tenant app where you have some sort of "Account" model and then all your existing models are scoped to it ... in other words, if this was a blog app, your Account has_many :posts, etc.
With this approach, you can identify accounts by subdomain ... have people choose their subdomain when they create an account and go from there.
It's pretty straightforward to do. If you need add billing into the mix, you might look at the SaaS Railskit (which handles all the signup and subdomain stuff) or Chargify.
You can also identify accounts Twitter-style ... with http://myapp.com/someuser
