similar to: using sessions to find who is online

Let''s say I have an application and I want to create an admin program that will show me who is currently online using the application. I don''t know the best way to do this. Assuming I am storing my sessions in the default PStore, I don''t suppose there is any method that lists all the active sessions, is there? The only way I can think of to do this is to setup a

Hi Shelby, No prob, You are having trouble b/c you don''t call @festival.valid? before this line: if !(@festival.errors.invalid? :name ) # => true if name is invalid I wasn''t clear about it in my post, but ActiveRecord::Errors#invalid? doesn''t actually do validations. It just looks at the associated errors object (which is empty if validation hasn''t

Using a <%= form_tag ... %>, how do I give a form a name, so that I can reference it with javascript? I sure can''t figure this out from the docs... Thanks, Shelby PS - what I am trying to do is just have the focus in the first form field when the form is loaded. There has to be an easy way to do this, but I can''t figure it out... -------------- next part --------------

How does one do a SELECT MAX query in rails? I''ve searched and searched and tried lots of things with no luck. I want to implement "SELECT MAX(column_name) from table_name and have it return the maximum value from column_name. I just need to get that one value, not the whole object... Thanks for any ideas...

I have a database field called dates in which I am trying to serialize an array of DateTime objects. When I unserialize them, they are coming back in as Time objects. I know this, because I am getting errors that say "comparison between Time and DateTime failed. Why is this happening? Is there a way to prevent it?? Thanks Shelby -------------- next part -------------- An HTML attachment

I''m having an argument with my son :) I have a table with about 1500 objects called entries. I need to do something with about 100 of them (schedule manually) I say I should just mark them with a boolean when I have scheduled them. (manual == true) My son says I should pull them out of the entries table and copy them to new objects (lets call them "manual" objects, and store

I have a rather complex object with a number of attributes. For a variety of reasons, I would like one view to create the object with only a couple of fields completed, then a second and third view to finish all the fields. I would like the model to validate_presence_of all these fields, since eventually I need them all there, and I would like each page to validate its portion of the fields that

I have an application that is used by only a small number of persons. This app stores its sessions in the database. When the user logs out, the session is removed, but of course, there is always the possibility that the user will forget to logout, and the session will go stale. In other webapps, I have used a sweeper ruby script that I run as a cron job to periodically clean these out. But I

Reading the Agile book, I can''t find a single command to save a collection. The save command seems to operate on only individual objects. Lets say I have a collection that I have received from a find_all command. I want to go through and change some attributes in various objects in the collection. Then I want to resave the whole collection back to the database. I don''t think

I''m studying the Agile Development with Rails book. In the chapter that first sets up the depot application (page 68), there is this bit of code from a view: <% for product in @products %> <tr> <% for column in Product.content_columns %> <td><%=h product.send(column.name) %></td> <% end %> etc... I am trying to absorb both Ruby and

I am confused about ruby fast C bindings. Does the command: gem install mysql install these? Is this page: http://www.tmtm.org/en/mysql/ruby/ the home page for these bindings? If so, it gives no instructions about installing them with using gem. Wondering if this is all the same??? Thanks for any help...

I have rewritten a java webapp into rails. The database structure is basically the same except that: 1) in the legacy app, several of the tables did not use ID numbers, but relied on other fields as the primary key 2) in the legacy app, there is a join table that uses email address and category names to do the join, not ID numbers I would like to move or change this database to match my new

I am trying to set up Hunt Groups and I am having some issues. Here is what I am trying to do. All my users actually register with OpenSIPS. Asterisk is using Realtime and I have set up a MySQL View Table so that Asterisk see's all the SIP users info that OpenSIPS has.

I have an ActiveRecord model (called Festival) that contains an array of "FestDate" objects serialized into a sql text column of the Festival object. (like the Agile book first edition describes on p. 205) The FestDate objects themselvs are not ActiveRecord objects. (of course, otherwise they would be in their own table...) When working with a Festival, I would like to use various

I have a bit of code in a controller that looks like this: @current_festival.monitor_preferences.each do |pref| if pref.user_id == @me.id pref.preference = params[:monitor_pref] #pref.save end end @current_festival.save_with_validation(false) the Festival class has_many :monitor_preferences the MonitorPreference class belongs_to :festival In the configuration above, the

I would like to use the collection_select with a simply array as the source of the collection.

Normally, in a rails app, all one would have to do is call set_facebook_session, or the ensure_* filters to get a valid session. I''ve been looking through the sessions code to figure out how to get a valid session for desktop applications (or unit tests)--basically outside of rails controller. As far as I can ascertain, you should just be able to do this: require
