I have the following models:
User
Apps
Service
Apis
A User has a list of Services he/she can access.
When creating an App I need to be able to add/remove services to it based on the Services a User can access. The same applies for editing an App.
We are using simple form. The association method is great for displaying Services with a checkbox to add / remove from the App.
The problem we face is that Services have Apis and we need to display information related to the Apis under a Service. A User still needs to be able to select a Service to add/remove from an App, as well as display information about it's Apis below.
It's seems the association method in simple form does not support the functionality we need to display information related to Apis in addition to being able to add/remove an Service from an App based on the User's list of Services he/she can access.
We have spent some time trying to figure out how to solve this problem e.g., nested forms, array parameters, simple form api, etc.
I would think there would be a Rails way to do this.

The question is fairly simple, but I've yet to find an answer to it. Is it possible to use Google+ API in an asp.net-mvc web app that requires multiple tiers of users?
For example, this app basically needs three sets of users and permissions associated with each: Admins, Members, Guests. Mind you, I've never handled user authentication of any type before, so I'm happy to hear suggestions for other frameworks if you think those would be better.
I think its going to be very hard for you to get three sets of user credentials in a single app.
For you to be able to authenticate as user one your going to need user one to authenticate your application then you will have access to that users data. If you need access to user twos data your going to have to have that user authenticate your application. If you need access to both users the same time its going to be very hard for you to get this access unless they are both using the same computer together.
While it is possible to get a refresh token for user one returned which you could store on your server some place and then use that to access user ones data when user two is on their machine. This becomes a gray area as you are responsible of holding user ones data private especially from user two.
as for your different leaves of users thats just part of your system it should just be a matter of strong the users ids associated with their role within the system.
None of this has anything to do with doing this in .net. You could probably work it all out using the .net client library. Web applications (ASP.NET MVC)
In the Simperium documentation/help section there is the following text:
All the data that is created seems like it must be tied to a user - is
that correct? Is it possible to have data that isn't tied to a user -
say a database of locations or beers?
Yes, though this isn't very clear yet. You can create a public user
(i.e., a public namespace) with an access token you share with other
users of your app so anyone can read/write to that namespace.
It's possible to limit this to read-only access as well if you need to
authoritatively publish data from a backend service.
Is there an actual example with this?
The scenario I have is as follows
My app will have a calendar
The primary user can add and remove data from the calendar
They will want to invite other users to add and remove data, my thought is that they can give them a token, the user can use their email address and this token to sign in
Am I on the right track?
You're definitely on the right track, but a little too far ahead on that track. The scenario you described is a great fit for Simperium, but sharing and collaboration features aren't yet released.
The help text you quoted is for authoritatively pushing content, for example from a custom backend to all users of your app. An example of this would be a news stream that updates on all clients as new content is added.
This is quite different than sharing calendar data among a group of users who have different access permissions, which is actually a better use of Simperium's strengths. We have a solution for this that we've tested internally, but we're using what we've learned to build a better version of it that will be more scalable for production use.
There's no timeline for this yet, but you'll see it announced on your dashboard at simperium.com.
I'am figuring out how the build a social network kind of site in Rails. In my site I've a User model. User can add photos, videos, text messages, events etc. Al these kind of updates are stringed together via a polymorphic association to the model Update.
Now for example a certain user follows 10 other users. What is the best way to created an overview of all the updates from the users that this certain user follows.
This post may help. It saves all the activities using the model in a table and then simply draws on them to create the activity stream.

This gem may also be of some use - looks like it largely does the job for you.

I need to develop an application which should help me in getting all the status,messages from different servers like Twitter,facebook etc in my application and also when i post a message it should gets updated in all the services. I am using authlogic for authentication. Can anyone suggest me what gems/plug-ins i can use..
I need API help to get all the tweets/messages to be displayed in my application and also ways to post the messages to the corresponding services by posting it from my application. Can anyone help me from design point.
Walk through what you'd want to do in your head. Imagine the working site, imagine your webapp working before you start. So your user logs in (handled by authlogic) and sees a textbox called "What are you doing right now?". The user fills in a status message and clicks "post". The status message appears at the top of their previously posted messages.
Start with the easy part. Create a class that posts to two services. Use the twitter gem and rfacebook to post to two already defined services. In the future, you'll want to let the user associate services to their account and you would iterate through the associated services and post the message to each. Once you have this working, you can refactor or polish the UI a bit to round out this feature. I personally would do the "add a social media account to my profile" feature towards the end.
Harder is the reading of the data (strangely enough) because you're going to have to figure out how to store it. You could store nothing but I suspect you'd run into API limits just searching all the time (could design around this). I would keep a little cache of posts associated to the user's social media account. In this way, the data model would look like this:
A user has many social media accounts.
A social media account has many posts. (cache)
Of course, now you need to schedule the caching of the posts. This could be done manually, based on an event (like when they login) or time based. So when the update happens, you load up the posts for that social media account and the user will see the posts the next time they hit the page. For real-time push to the client's browser while they stare at the screen, use faye (non-trivial) and ajax to pull the new posts to the top of the social media stream view.
The time based one is tricky because you'd either have to have a cron job run or have rails handle it all with a gem like clockwork. But then you have to leave rails running. I've also solved this by having a class in /lib do all the work and a simple web call kicks off the update. But it wasn't in a multi-user use case. So that might not work. In any case, you'll want to have some nice reusable code for these problems since update requests can come from many different sources.
You'll also have to deal with the API limits. When pulling down content from twitter, you won't get everything. That will just have to be known by the user or you'll have to indicate a "break in time" somehow.
The UI should be pretty easy (functionally anyway), because you know which source the post/content is coming from. It'd be easy to throw a little icon next to the post to display which social media site it's coming from.
Anyway, good luck, sounds like a fun project.
Please consider the following setup:
Multi-tenant webapp.
Tenants create company accounts and company accounts have user accounts under them.
Users have roles, there's a special role "Owner" (the user who created the company account).
I'd like to have users to edit other user accounts (some admin tasks), but two conditions must be met:
Noone may edit owner's data (except for owner, when he's editing his own profile, and own profile editing is the same user editing).
Users may access user data and edit users only within their company account.
The app uses MVC architecture. Currently I check for those two conditions in the web layer and it works for me, but I have some concerns. If I go with some sort of API or some other type of data consumer, I may "forget" to re-inforce these conditions. Also, there will be other objects in the app with similar functionality requirements and which will have similar restrictions on them, so it's better for me to come up with some sort of pattern which will enforce my restrictions on data access level.
Could anyone recommend some approach worth looking into?
Thanks!
I beleive aspects or interceptors should be able to help you. If you work with objects you should be able to intercept requests containing your business data and check wether your user is allowed to work on it. The interceptor could then stop or proceed the execution.
