Google App Engine + Form Validation
- by Iwona
Hi,
I would like to do google app engine form validation but I dont know how to do it?
I tried like this:
from google.appengine.ext.db import djangoforms
from django import newforms as forms
class SurveyForm(forms.Form):
occupations_choices = (
('1', ""),
('2', "Undergraduate student"),
('3', "Postgraduate student (MSc)"),
('4', "Postgraduate student (PhD)"),
('5', "Lab assistant"),
('6', "Technician"),
('7', "Lecturer"),
('8', "Other" )
)
howreach_choices = (
('1', ""),
('2', "Typed the URL directly"),
('3', "Site is bookmarked"),
('4', "A search engine"),
('5', "A link from another site"),
('6', "From a book"),
('7', "Other")
)
boxes_choices = (
("des", "Website Design"),
("svr", "Web Server Administration"),
("com", "Electronic Commerce"),
("mkt", "Web Marketing/Advertising"),
("edu", "Web-Related Education")
)
name = forms.CharField(label='Name', max_length=100, required=True)
email = forms.EmailField(label='Your Email Address:')
occupations = forms.ChoiceField(choices=occupations_choices, label='What is your occupation?')
howreach = forms.ChoiceField(choices=howreach_choices, label='How did you reach this site?')
# radio buttons 1-5
rating = forms.ChoiceField(choices=range(1,6), label='What is your occupation?', widget=forms.RadioSelect)
boxes = forms.ChoiceField(choices=boxes_choices, label='Are you involved in any of the following? (check all that apply):', widget=forms.CheckboxInput)
comment = forms.CharField(widget=forms.Textarea, required=False)
And I wanted to display it like this:
template_values = {
'url' : url,
'url_linktext' : url_linktext,
'userName' : userName,
'item1' : SurveyForm()
}
And I have this error message:
Traceback (most recent call last):

self.choice_value = smart_unicode(choice[0])
TypeError: 'int' object is unsubscriptable
Do You have any idea how I can do this validation in different case?
I have tried to do it using this kind of:
class ItemUserAnswer(djangoforms.ModelForm):
class Meta:
model = UserAnswer
But I dont know how to add extra labels to this form and it is displayed in one line.
Do You have any suggestions?
Thanks a lot as it making me crazy why it is still not working:/
