• How can I employ "if exists" for creating or dropping an index in MySQL?

  - by Paul

  I was wondering if there's a way to check if an index exists before creating it or destroying it on MySQL. It appears that there was a feature request for this a few years back, but I can't find any documentation for a solution. This needs to be done in a PHP app using MDB2.

• Why does OpenID look so hard to implement?

  - by user198729

  I read through this post: http://stackoverflow.com/questions/741345/how-do-i-implement-direct-identity-based-openid-authentication-with-zend-openid Why does it look so complicated to implement? IMO, it's just to send request to a remote site and retrieve the response. What's the problem those OpenID libraries are dealing with?

• Is is faster to filter and get data or filter then get data ?

  - by remi bourgarel

  Hi I have this kind of request : SELECT myTable.ID, myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE EXISTS(SELECT * FROM myLink WHERE myLink.FID = myTable.ID and myLink.FID2 = 666) myLink has a lot of rows.

• Start timer on web application start

  - by brainimus

  I would like to start a System.Threading.Timer in my application when it launches (maybe deploy is the correct word). I have seen that you can use Application_Start() but this is only fired once the first request comes to the application. I need the timer to start as soon as the application is running so that it can check for work to process even if a user is not interacting with the site. How can I get the application to start the timer once it is up and running?

• Django ModelAdmin.save_model() -vs- ModelAdmin.save_formset()

  - by anonymous coward

  I want to ensure that a user editing a particular model is saved in that models updated_by (FK User) field. I'm using mostly ModelForms (not necessarily the built in Admin), and wondering: In what cases would I need to override ModelAdmin.save_model() or ModelAdmin.save_formset()? Or, is that doing it wrong? If it's just the models' save() method that needs to be overridden, is there a proper way to access the request object there?
