  • Convert SQL query to Ruby help

    - by Verloren
    Hey all, I need to query my database table to find which employee has the most support tickets related to them. I can do this just fine using this MySQL query: SELECT employee_id, COUNT(id) AS number_of_tickets FROM tickets GROUP BY employee_id ORDER BY number_of_tickets DESC LIMIT 1; How would write this in Ruby-on-Rails? Thanks very much for your assistance. I use Ruby version 1.8.6, Rails version 2.2.2 and MySQL Server version 5.0.

  • optional local variables in rails partial templates: how do I get out of the (defined? foo) mess?

    - by brahn
    I've been a bad kid and used the following syntax in my partial templates to set default values for local variables if a value wasn't explicitly defined in the :locals hash when rendering the partial -- <% foo = default_value unless (defined? foo) %> This seemed to work fine until recently, when (for no reason I could discern) non-passed variables started behaving as if they had been defined to nil (rather than undefined). As has been pointed by various helpful people on SO, http://api.rubyonrails.org/classes/ActionView/Base.html says not to use defined? foo and instead to use local_assigns.has_key? :foo I'm trying to amend my ways, but that means changing a lot of templates. Can/should I just charge ahead and make this change in all the templates? Is there any trickiness I need to watch for? How diligently do I need to test each one?

  • Is there a way to create a step chart using the Google Charts API?

    - by Nathan
    I'd like to use the google charts API to create a step chart for my Rails application. Preferably using the annotated timeline Google has (since it has a nice wrapper plugin for rails): http://code.google.com/apis/visualization/documentation/gallery/annotatedtimeline.html However, there doesn't seem to be a way to create a step chart using the annotated timeline or any other chart in the Google API. I'm looking to make a plot like this: If there is no way to do this with the google API, is there an alternative graphing library that can handle such a task?

  • Why do i get a circular reference exception when calling to_json on an ActiveRecord::Relation

    - by midas06
    In Rails 3 (beta 3 on 1.8.7), when calling to_json on a relation i get a circular reference exception. Converting that relation to an array first, and THEN calling to_json works. Code That fails: Model.where().to_json (Where model is any model in your Rails 3 app) Code that works: Model.where().to_a.to_json This can be reproed on the console. Has anyone else run in to this? Is this expected?

  • How to let users post links/images to Facebook, Twitter, Buzz etc... from a Rails based website?

    - by wgpubs
    I'd like to offer users the ability to post images / links to articles from my web application to Facebook, Twitter, Buzz and any other social network. A perfect example of the functionality I'm trying to replicate is mashable.com ... where each social network is represented by an icon that a) shows the number of shares AND b) allows users to click on it to post to that specific network. Don't know if it matters ... but the site is built using RoR. Thanks
