I'm still not very clear on the "recommended" way to create forms in awake(), since the way I'm doing it, by manipulating self._forms, doesn't seem very natural. If this is the right way, I can create an example for your Examples folder. If not, and you find the time before the next release, an example of a form created in awake() would be helpful, I think. :)
Thanks!
Not sure if I am doing it the "correct way" but I have a page where the form is generated on the fly each time.
The form only needs to exist if it needs to be rendered for the user, or if it needs to be validated. I am not using the mixin and doing all the processing explicitly.
So I have base class w/ def initForm(self):
'''Initialize the base form. This should be the same for all classes, there is a hook
to init2 to add controls specific to the report being created.'''
f1 = self.form1 = Form.Form( )
f1._setFormID(self.reportID)
f1.addField( Fields.SelectField('rowsPerPage', label="Records per Page") )
.....
Then if the user send forminfo I do:
def showReport(self)
self.initForm()
fields = self.request().fields()
self.form1.process( fields )
# save the user values
currentValues = {}
for f in self.form1.fields():
currentValues[f.name()] = f.value()
formValid = self.form1.isSuccessful()
if not formValid:
f1 = self.form1
put back the user values
f1.seed(currentValues)
self.writeForm('Error')
else:
self.writeReportHTML()This has the disadvantage of building up the form class each run. You may want to use some instance caching in initForm to save the form between runs, and then call something to .sleep each form in servlet.sleep.
There are some good examples of this type of caching relating to Cheetah templates.
