I'm trying to figure out the best way to hide certain fields in user profile based on user's preference. So far I'm using a boolean field and an if, then statement. <% if @user.show_email == 'true' -%> <%=h @user.email %> <% else -%> hidden <% end -%> I was wondering if I could use declarative_authorization or some other better me...

I have a Mongrel cluster behind nginx and am trying to get nginx to serve up the static contents of my site with the following rule (RESTful URLs): location / { if (-f $request_filename) { break; } if (!-f $request_filename) { proxy_pass http://mycluster$request_uri; br...
At the moment I store each option in its own class attribute but this leads to hard to read code when I need to access the passed options from instance methods. For example if I pass a column name as an option I have to use self.send(self.class.path_finder_column) to get the column value from an instance method. Notice I have prefixed ...
Well, not really reinventing, however, we have a large content-based website which handles load (after we fixed the SQL pooling issue) to a certain point, then we just run out of steam. A lot of this is due to bad code we are trying to fix up, but a lot is just due to the level of requests etc. We were considering page caching, because ...
On my login form I want to display one simple error message like "Sorry, email or password is invalid" whenever user enters invalid email and / or password; instead of standard fancy message with heading and unordered list. ...

I have a Rails 2.3 web application that uses the collection_select helper with :multiple => true to handle a habtm relationship. This is working fine to set one or multiple values, however I have not figured out how to allow to REMOVE all selections. Code: <%= f.collection_select :category_ids, Category.find(:all), :id, :name, { :...
I have a rails controller which must return a .csv file and I'd like this page to use cache. The cache works fine when I use a .xml format (it returns 304 http status), but when the format is csv, it always returns 200 http status. here is my controller code: def index @machines = Machine.all respond_to do |wants| want...
For example, I need to convert time from UTC to local. And I use Time.zone to do this. 1.Time.zone = local_zone_name 2.Time.zone.utc_to_local(utc_time_var) But I'd like to avoid the usage of the first line since I believe this approach modifies the class variable. Any suggestions? Thx in advance! ...

Is there anyway to setup simple task scheduling inside of a rails app? There are pieces of code that I want to run every hour, or every day or every week. I don't want to break them out into separate scripts that I then have to schedule via cron jobs. If I did that, then I'd have to remember to backup the scripts, and if I rebuild a serv...
I saw this on a blog today, and I thought, finally! Rails will have something like HQL or Linq. Um, or not. I couldn't find anything about this. What I really want to know: will I be able to forget what the tables are called and use the object names only? Can I finally forget join syntax? I'd like to do that before I start forgetting ev...
I'm using ActiveResource to consume a REST service. The xml from the service looks like: <Person> <FirstName>Kevin</FirstName> <LastName>Berridge</LastName> </Person> ActiveResource parses this just fine, but it uses the names verbatim. So the model class will look like: p = Person.find(1) p.FirstName p.LastName I would much ...

Is there a standardized command to determine the version number of a plugin, similar to ruby script/about? For example, I need to figure out which version of exception_notification I'm running.

When you get a new badge on stackoverflow.com, a bar appears at the top of the screen informing you of your achievement. It sticks around until the user closes it. I rather like that system of informing the user about new news related to the site or their account. It's fairly unintrusive, but still clearly communicates the information...
