I have a problem with dynamic added field to the form. The following
code creates one input field and two submit buttons. I would like to
add more (up to 4) input fields after pressing "more" button. It does
not work and I have no idea how to solve it.
import re
from WebKit.Page import Page
from FormKit import Form, Fields, Validators
from FormKit.FormKitMixIn import FormKitMixIn
class DynamicProblem(FormKitMixIn, Page):
def __init__(self):
Page.__init__(self)
notEmpty = Validators.NotEmpty()
f = self.form = Form.Form()
self.addForm(f)
f.addField(Fields.TextField('msg', validators=[notEmpty]))
f.addField(Fields.WebKitSubmitButton('more'))
f.addField(Fields.WebKitSubmitButton('send'))
def sleep(self, trans):
self.resetForms()
Page.sleep(self, trans)
def writeHTML(self):
self.write(self.form.dump())
def extendForm(self):
notEmpty = Validators.NotEmpty()
f = self.form
nr = len(filter(lambda x:re.match(r'^msg',x),
self.form.values().keys()))
if nr < 4:
f.addField(Fields.TextField('msg%d' % nr,
validators=[notEmpty]))
def actions(self):
return ['more', 'send']
def more(self):
if self.form.isSuccessful():
self.extendForm()
def send(self):
if self.form.isSuccessful():
pass
