Could someone verify my approach:
class BasicForm(SitePage, FormServlet):
def __init__(self, forms=None):
SitePage.__init__(self)
if forms is None:
f = FormDefinition(self.name(), [], [], name=self.name())
forms = [f.mutable()]
FormServlet.__init__(self, forms)
def writePageContent(self):
formProcessed, data = self.processForm()
if data == 'invalid':
req = self._erroneousRequest
name = self._erroneousFormName
log.error("error on form %s request %s", self, req)
if not formProcessed:
self.renderForm(None)
else:
self.handleCompletedForm(data)
def handleCompletedForm(self, data):
pass
def renderForm(self, fields):
form = self.formDefinitions()[self.name()]
layout = self.buildForm(form)
rf = self.renderableForm(defaults=fields)
self.write(rf.htFormLayout(layout, spacing=10))
def buildForm(self, form):
# do form.replaceField() to update form definition.
# and then return the layout (used by htFormLayout())
pass
Is it a proper way to deal with dynamic forms? Any gotchas?
Seems like it works OK.
