this is probably strange question but I wanted to make rails app that would function as regular desktop app.
I'm making regular web app, but I will have admin function where I manage clients. I'm not very confident with security of my app and I will be only one who uses it so I thought maybe I can use this part of code only on my windows machine.
I figured it out because I don't have SSL certificate and I wouldn't want to put something on web if i will be only one who uses it.
I also know that Rails is webframework, but is is only framework i know how to work with.

I've inherited a Rails 3.2 production environment which is 'humming' away nicely.
The client now wants another major piece of work doing but I want to do it in Rails 5. The web address would be the same for both the old site and the new project. The new project would be additional functionality which would be accessed via the old site.
Any one know of a way of keeping the old site running whilst I develop and deliver the new work via Rails 5? Eventually if this all works then I get the opportunity to migrate the old site to Rails 5. However for the moment I need to serve up both Rails 3.2 and Rails 5 from the same site.
It's possible to do what you describe with a reverse proxy, e.g. nginx, configured to serve from different web servers based on different paths on the same host. This answer has some details on how to do that. We would need to know how your website is hosted in order to give more details on exactly how to do that.
However, there are other concerns that come up when you start separating your apps which you may not have considered. For example, if your website allows users to log in, do you want them to still be logged in when they visit the new site? To do so transparently will require sharing the session cookie, which this post describes a bit (you'll need to use the same secret key for both apps, or use a remote session store like Memcached). I'm not sure if it'll work properly when shared between Rails 3.2 and 5, though.
As a final note, breaking up your monolithic app into a distributed system is never a decision to take lightly. It would likely end up being less work, and less overall architectural overhead, to simply invest the time in upgrading from 3.2 -> 4.0 -> 4.2 -> 5.0.
Personally I wouldn't touch that old app and its server, especially if the client is happy. Deploying the new app to a new server or a container service like heroku is something you should consider.
I'm planning an app for work and venturing into potential features which I've not used before.
Essentially I need to be able to access files on a network share, read, write and delete files as well as amend the file names. As a pretty closed platform I'm not sure whether iOS is capable of such a thing and if it is, what features should I look for to begin researching?
My Google-Fu hasn't come up with anything thus far so hopefully looking for someone to point me in the right direction.
Thanks.
I know this isn't very secure, but I'd personally create an ASP.NET app on your target Windows Server, or a different Server on the domain. Create web services exposed, and make an iOS app with UIWebView. You can do RPC calls from the web service that do WMI/ADSI/File System manipulation. You can prompt for domain credentials, and do remote calls essentially is the gist.
You could expose the web app so that your app can access it from local network, or URL. If you were to access it from outside I'd suggest using some secure credentials in Windows/IIS.
Some years ago I created a "mobile-friendly" web app that allowed me to manage servers, perform RPC, and do basic Active Directory queries. Also allowed file listing and deletion/moving/copying with some creative scripting. It was essentially a ASP.NET/C# web app that loaded in a iPhone app. UIWebView in iOS was a able to load it, used AJAX and some other client side scripting that looked decent. You'd essentially have to make sure that your web app renders properly in Safari/UIWebView (which is bastardized safari).
Here's a link to a demo of what I created:
https://www.youtube.com/watch?v=czXmubijHwQ&t=12s
I ran it in a browser, but it'd run from my PSP, Android test devices, iPod Touch, Blackberry, etc.
I was recently building an internal business database web app using Ruby on Rails 4 and Postgres. The plan was to make the app available to all our employees using Devise for authentication and hosting on Heroku.
Toward the end of development, a request was made to include some highly sensitive information in the app including social security numbers, etc. Thus, instead of heavily worrying about online security we are planning to make this app only run locally on one Mac and not have it available online. The app will only be used about 5 times a month by one person. Instead of requiring that person to launch a postgres server and a webserver via terminal (such as "rails server"), is there a way to package the entire Rails web app and database in to an application so it could be run similar to other OSX apps?
If anyone knows a PC solution instead, that is also a (less preferred) option.
At this point, we realize we should have developed a xcode app, but now that the development is mostly complete with some tricky UI, we would rather not have to recreate the functionality in xcode.
Though I haven't used it myself, what your describing sounds pretty close to what Rubymotion offers
In the process of building a SPA, we opted for a combination of Rails API and Ember-cli.
From what we understand, the architecture of the app will be the following:
Rails API will run the back-end of the app, as an API
Ember-cli will run the front-end of the app, as a front-end MV* framework
Data will be served by Rails API to Ember-cli with JSON
What does not seem really clear though, is what should be the development workflow?
In other words, should we:
Build the back-end (rails models, etc), then build the front-end and finally connect both?
Build everything at the same time, but one feature at a time?
Go with another option?
I would recommend building both at the same time, in separate apps (that way you can test your API as an actual API rather than just a backend), but in close proximity to one another. This way you can make sure both play nicely with each other and you're getting the results you actually need, plus if something that you do on one causes an error on the other the bug will become immediately apparent.
Let me know if this answers your question enough, I can clarify/ give additional examples from here if you'd like.
I have built two rails apps that need to communicate and send files between each other. For example one rails app would send a request to view a table in the other apps' database. The other app would then render json of that table and send it back. I would also like one app to send a text file stored in its public directory to the other app's public directory.
I have never done anything like this so I don't even know where to begin. Any help would be appreciated. Thanks!
You requirement is common for almost all the web apps irrespective of rails, Communicating with each other is required by most modern web apps. But there is a small understanding that you need to get hold on,
Web sites should not directly access each others internal data (such as tables), (even if they are build by the same language (in this case Rails) by the same developer),
That is where the web-services comes in to play, So you should expose your data through web services so that not only rails application can consume that, but also any app that knows how to consume a web service will get benefit.
Coming back to your question with Rails, rails supports REST web services out of the box, So do some googling about web services, REST web services with rails
HTH
As a starting point, look at ActiveResource.
Railscast
docs
Message queuing systems such as RabbitMQ may be used to communicate things internally between different apps such as a "mailer" app and a main "hub" application.
Alternatively, you can use a shared connection to something like redis stick things onto a "queue" in one app and read them for processing from the other.
In recent Rails versions, it is rather easy to develop API only applications. In the Rails core master, there was even a special application type for these apps briefly (until it got yanked again). But it is still available as a plugin and probably one day becomes actually part of Rails core again. See http://blog.wyeworks.com/2012/4/20/rails-for-api-applications-rails-api-released for more information.
To actually develop and maintain the API of the backend service and make sure both backend and frontend have the same understanding of the resources, you can use ROAR which is great way to build great APIs.
Generally, you should fully define your backend application with an API. Trying to be clever and to skip some of the design steps will only bring you headaches in the long run...
