I'm building a site in which a catalog (of products) is shown and when clicked a Adobe Livecycle generated pdf will be opened. There are a few form fields and when the submit button is pressed, the fields will be submitted to the url http://localhost:3000/pdf-parser.

I have used PHP for awhile now and have used it well with CodeIgniter, which is a great framework. I am starting on a new personal project and last time I was considering what to use (PHP vs ROR) I used PHP because of the scalability problems I heard ROR had, especially after reading what the Twitter devs had to say about it. Is scalabil...

I am concerned whether Rails can handle the types of complex aggregations that are needed for a financial application and particularly whether the ORM can handle these effectively. In a financial application that I am thinking of using this for, there is a need to do lots of reporting of detailed financial data, aggregated in various way...
Hello. I've inherited a Ruby on Rails application that has a problem. I'm half way through some books on Rails, but haven't seen the answer to some questions yet. What is the best way to backup the application? Can I just tar -cvzf app.tgz app? I don't know yet if the app has a sqlite3 database or connects to a db server. What's the b...
I know that I can do this in Rails: <%="hello" %> but is there any way to do this <% echo "hello" %> and get it to show up in the response? I have tried response.write which almost worked, but did not... Edit: print or puts do not do it, because I do not want to write to the console. I want to write to the browser/HTTP client. Ed...

I was just reading up on ROR (haven't dived into it yet), and I hear that it isn't thread safe. Obviously, this doesn't mean that more than one person can't access your site at one time, so what exactly does it mean? Where do threads come into play in ROR? Do they just mean the request handling? ...
Also, I'm wondering what effect upgrading to Ruby 1.9 would have on legacy code from version 1.86. Is the new version backwards compatible? ...
I have a form that makes an Ajax POST request to insert a widget into my database. In the form, I have a select box where you can select from the widgets. After the db insert is made, I must update the select box. I actually just replace the entire form for now. Because the select box has the widgets, I must have a copy of the obje...

I love working with Rails but I keep tripping up against my own inefficiency: I'll spend time implementing some "useful" function only to discover subsequently that it was already in the framework, had I but known it! Particular areas of wheel reinvention for me are helpers and built-in class extensions recently-released features that...
Any recommendations of a recent tutorial, or guide, on uploading Rails applications to a (gs) rails container? I've followed a couple tutorials already, both of which haven't worked. ...
My employer, a small office supply company, is switching suppliers and I am looking through their electronic content to come up with a robust database schema; our previous schema was pretty much just thrown together without any thought at all, and it's pretty much led to an unbearable data model with corrupt, inconsistent information. T...
I have a case where I need to use pluralize to properly spell something. However, I need to render the html like so: <span>1</span> thing or, <span>3</span> things I could write a helper method, but I'm just making sure there isn't something in the box to do this. ...
Sending an email is usually called after an action on a model, but the email itself is a view operation. I'm looking for how you think about what question(s) to ask yourself to determine where to put the action mailer method call.

I have a Rails application that unfortunately after a request to a controller, has to do some crunching that takes awhile. What are the best practices in Rails for providing feedback or progress on a long running task or request? These controller methods usually last 60+ seconds. I'm not concerned with the client side... I was plann...

I've been using ZenTest to run all the tests in my Rails project for years and it's always been quite nippy. However, on my Mac it has suddenly started taking 3 times as long to run all the tests. We have 1219 tests and for the past year it would run all the tests in around 300 seconds on average. Now though, it's taking almost 900 se...
