  • Rails Multiple Models per Form, Optional FK Association

    - by ckarbass
    Given the following pseudo-code: Company has_many :jobs Job belongs_to :company I'm creating a form to post a new job. In the form, I want to have two fields for an optional company. On submission, if a company was entered, I want to either create or update the company and associate it with the new job. I know if the company exists by searching the companies table for the company's url. Is it possible to do this using form_for, fields_for, and accepts_nested_attributes_for given the company may not exist?

  • jQuery selector syntax gives Firefox warning

    - by FreekOne
    The following code stringref = "tab_2"; jQuery('.someclass a:not(.someclass #a_someclass_'+stringref+')').css('color', '#000'); gives me this warning in the FF 3.5.5 error console and I can't figure out why: Warning: Missing closing ')' in negation pseudo-class '#a_someclass_tab_2'. Is my syntax failing me or has FF gone bonkers ?

  • Using Ogg Vorbis in Flash/Flex applications

    - by Aravindan
    I am looking to use ogg vorbis, instead of mp3s to stream audio. It seems that Flash player does not natively support ogg. Is there a codec engine that can be embedded with the app itself that can play .ogg instead of .mp3? In general, what would be a better format than mp3 for streaming audio and that is supported by Flash?

  • SQL Server: Are temp tables or unions better?

    - by Jonathan Allen
    Generally speaking, for combining a lot of data is it better to use a temp table/temp variable as a staging area or should I just stick to "UNION ALL"? Assumptions: No further processing is needed, the results are sent directly to the client. The client waits for the complete recordset, so streaming results isn't necessary.

  • How to formulate a SQL Server indexed view that aggregates distinct values?

    - by Jeremy Lew
    I have a schema that includes tables like the following (pseudo schema): TABLE ItemCollection { ItemCollectionId ...etc... } TABLE Item { ItemId, ItemCollectionId, ContributorId } I need to aggregate the number of distinct contributors per ItemCollectionId. This is possible with a query like: SELECT ItemCollectionId, COUNT(DISTINCT ContributorId) FROM Item GROUP BY ItemCollectionId I further want to pre-calculate this aggregation using an indexed (materialized) view. The DISTINCT prevents an index being placed on this view. Is there any way to reformulate this which will not violate SQL Server's indexed view constraints?
