Re: django/Data Base Advice
Chris, I think was somehow in the same stage not so long ago... Here is how I went about it: 1. I watched a db-class video from time to time (teaches you what joins are etcetera). Using the ORM without db knowledge is ok if efficiency is not your main concern. Sooner or later you have to make database design choices and only relying on the community is going to slow you down. Good advice is expensive (time or effort). 2. Having read the docs on djangoproject.com (which are huge), I read djangobook.com, then I started building my own apps following some of the tutorials from https://code.djangoproject.com/wiki/Tutorials. I made myself a todo-app, for instance. There are about three or four tutorials for that and each of them adds some knowledge (the nettuts one is for true beginners). If you work on you app a bit you'll gain knowledge in testing, migrating, implementing design and much more. I always asked myself 'does my program solve a problem'. If it does not, you will get lost pretty quickly. 3. ? Not sure what the next step would be? Deploy a small website? Use third party OS code? Any suggestions?

Re: Using ForeignKey with dJango and PyAMF
According to this bug report, select_related is supposed to return the data, but it doesn't. Also, if I can't get the foreign key, is there a way around this? All I really need is the id of the foreignKey object. Any help would be much appreciated. I am a newbie to this architecture. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Using ForeignKey with dJango and PyAMF
By the way, all I really need is the parentBlock_id.

Using ForeignKey with dJango and PyAMF
Hi Everyone,
I have a ForeignKey field that is always null on the Flex client. I
have tried using select_related(), but it's still null. Any idea what
I am doing wrong? In the following sample code, parentBlock is always
null on the Flex client:
File: BlockVO.py
from django.db import models
class Block(models.Model):
blockName = models.CharField(max_length=200)
blockLabel = models.CharField(max_length=200)
blockColor = models.PositiveIntegerField()
xBlockPos = models.IntegerField()
yBlockPos = models.IntegerField()
parentConnectionType = models.CharField(max_length=200,
blank=True, null=True)
parentBlock = models.ForeignKey('self', blank=True, null=True)
def __unicode__(self):
return self.blockLabel
File gateway.py
# To get all Blocks
def getBlocks():
return Block.objects.all().select_related()
File page.as
private function onResult_blocks(data:Object):void {
var answer : Array = ArrayUtil.toArray(data);
trace("Server returned " + answer.length.toString() + "
block(s)");
for each (var item:BlockVO in answer) {
if(null == item.parentBlock) {
trace("for bloc id=" + item.id +
"parentBlock is null");
} else {
trace("for bloc id=" + item.id +
"parentBlock_id=" +
item.parentBlock.id);
}
var newBlock : Block = new Block(workspace, false,
item.blockLabel, 0x66FF66, BlockSpec.REPORTER, null, item);
blocks.push(newBlock);
addChild(newBlock);
}
}
