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...

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 --------------

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

Hi, I just wrote an article on how to easily create a REST API for Ruby on Rails applications: http://www.xml.com/pub/a/2006/04/19/rest-on-rails.html It describes how to create everything from the ground up and includes information on testing your API too. -- Thanks, Dan Kubb

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 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??

I''ve noticed in the source code that Mongrel handles the IF_UNMODIFIED_SINCE header. I thought this rather odd, since IF_UNMODIFIED_SINCE is generally only useful with PUT. Even more odd is that there is no mention of IF_MODIFIED_SINCE in Mongrel which is useful with GET (although not as useful as IF_NONE_MATCH of course). Is this a bug in Mongrel? -Tim

Does anyone have an example of using REST and submitting data through a POST operation and then possibly loading that data with activerecord. Also, if you have client code written in another language (java,.net, C), would you have that code as well? Berlin Brown

I''ve run into an issue with my rails application being unable to properly set cookies on Mongrel 0.3.18. If I run the simplified code below in Mongrel 3.14.4, both cookies are properly sent to and saved by the browser. With the same code in 0.3.18, only the auth_token cookie is created (if I switch them, only the userid as it will only properly create the first cookie in the list.)

So, I''m working on adding iCal support to my app. Since I want to restrict users to their own calendars, form-based authentication isn''t going to work, so I''m using the Basic HTTP Authorization from this page - http://blogs.23.nu/c0re/stories/7409/ Everything works fine in my dev machine, but on the server (Site5), I get the login prompt ad infinitum. Has anyone run

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

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

Folks: I''ve posted a really basic e-mail address verifier to http://wiki.rubygarden.org/Ruby/page/show/VerifyEmailAddress I''d appreciate folks who understand DNS and SMTP having a look at it to see if it looks reasonable. You could comment here or, possibly more usefully, comment on the wiki page itself. Thanks Dave

I''m still relatively new to ROR, but I like what I see with the database-neutral approach of Schemas. In the spirit of keeping it simple and minimizing the number of files and location of information, does ActiveState currently allow me to go ahead and place other low level model information such as validation requirements and associations inside the schema rather than putting it in

Hello all After being told of a funky date validator I will ask again for another validator :) Does anyone know of a plugin that validates that a field is the correct syntax for an IP Address? Thanks Jeff -- Posted via http://www.ruby-forum.com/.

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...

Hi. I''m using Apache2.2 built from source + mod-proxy + ssl + svn. Everything works fine but I''m sure you I could disable a ton of modules during the build process and in httpd.conf to speed things up and run a tighter memory footprint. Has anyone bothered building Apache2.2 from source disabling all the unneeded modules. I am planning on going through the Apache docs but I

Greetings all, This is the first release of the SuperImage plugin. The idea is you upload images to the database, and then pull them out at any size you want. Combine this with caching and it will stay light and fast.

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

What is the proper syntax to apply a css class to a link created using link_to? I''ve tried <%= link_to("details", :class => "details", :action => "edit", :id => event) %> but that creates a link which looks like /admin/events/edit/3?class=details which is not what I''m looking for. Kyle Heon
