[google-appengine] Re: Python GAE version of Rails' validates_uniqueness_of
Thanks Nick. Always appreciate the help!
Regarding the prefix you put in the key_name, on hunch it looks to
have other benefits. I suspect memcache. Do you have any other
pearls you can toss out about it, and ways that known key_name
prefixes can be leveraged?

[google-appengine] Python GAE version of Rails' validates_uniqueness_of
I discovered that my 'Account' model happily created multiple instances of user 't...@example.com' without complaint during testing. (I know, fix my code). Short question: What's the lightest way of ensuring value uniqueness between entity values? I've read up on the Property class constructor argument "validator" and got to wondering if there is a RoR-like library of prefab validators. It would be great if I could do something like this: from google.appengine.ext import validation class Account(db.Model): user = db.UserProperty(required=True, validator=validation.unique(db.UserProperty) ) ... related resources: http://code.google.com/appengine/docs/python/datastore/propertyclass.html http://googleappengine.blogspot.com/2009/07/writing-custom-property-classes.html --Daniel Rhoden --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: YUI widgets and GAE
If its not too far committed, you might entertain using jQuery instead of YUI. There is a plugin for just about everything. Here is a blog entry I found regarding a guy who evaluated YUI and then ended up with jQuery. http://henritersteeg.wordpress.com/2009/03/11/user-interface-widgets-from-yui-to-jquery-ui/ In my limited use of jQuery I've found it incredibly easy to use. I love how many options there are for any one widget. The variety gives me a better chance of using the thing right out of the box.

[google-appengine] Re: Registered app not showing
Dag-nabit. I just discovered that I never registered the account cleanslateso...@gmail.com . I did some Googling and found out that account was used at one point by a similar entity (what are the odds??) So sorry for the confusion. I hope this doesn't mess anything up by activating that gmail account for the app. On Jul 29, 2009, at 11:39 AM, Nick Johnson (Google) wrote: > Hi Daniel, > > Signing up with an additional account is fine, as long as you don't > use it to create apps that attempt to evade the free quota limits by > distributing your traffic across multiple apps.

Thanks so much! I DO have that account. If I sign up with that account as well, wouldn't I be in violation of having more than one App Engine Account? Is that ok now?

[google-appengine] Anything better than naked domains?
At any of the paid levels or free, is there any better support of private domains than just naked domains, mapping to http:// .yourdomain.com ? For example, lets say I have domain 'mydomain.com' and I registered 'mydomain' on App Engine. It would be pretty silly having people go to 'http://mydomain.mydomain.com/' So I'm wanting to know, is there a way I can have 'mydomain.com' BE my domain for my app? Thanks. Also, will there be any DNS offerings? --Daniel Rhoden Guntersville, Alabama --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

A String can go a long way as well. Hopefully your property table has some sane restrictions as to what can go in it.
