Re: [SQLObject] Preparing for 0.4

Hallo,

Does taking out lazy fetching mean, that changed objects now will have
immediatly visible changes even under Webware? 

I still cannot solve my problem, where objects, that are referenced
by other classes, don't have their changes visible. 

A simple example is an editable Tip of the Day app, where a Day can
have multiple tips.

The model is: 

class Tip(SQLObject):
	_columns = [ 
		IntCol("dateID"), foreignKey='Date'), 
		StringCol("text") ]
		
class Date(SQLObject):
	_columns = [ 
		DateTimeCol("start"), 
		DateTimeCol("end") ]
	_joins   = [MultipleJoin("Tip")]


Now my Page has an action to change the Tip of a Day

	def changeT(self):
		req  = self.request()
		id   = req.value('id', None)
		text = req.value('text', None)
		t = Tip(id)
		t.text = text
		self._msg = '''Changed: %s ''' % t.id
		self.writeBody()

It also has a "listTips" area, whose pseudo code looks like this:

for day in Date.select("all"):
	prettyPrint(day)
	for tip in day.tips:
		prettyPrint(tip)

Now this last printing of the tips does not reflect changes done in
"changeT" until the AppServer is restarted. This is really driving me
nuts... 

ciao
