I have just recently started using forms. I was avoiding them because
I thought they were not very DRY, but discovered I need them for added
flexibility such as displaying field lengths for example.
Anyway, I have created a Form for a Survey object that I use. If I go
to my edit page for a Survey, everything works perfectly. If I go to
do a simple add new (like right out of the docs), I always receive an
error "NoneType' object is not callable". So I am assuming I am trying
to use something not in existence yet, but it seems bizarre to me (but
I am a form noob and hoping I am doing something stupid (at least 1
thing)). Here is my model
class Survey(models.Model):
"""Highest level class that defines the attriutes of a survey"""
STATUS_CHOICES = (
('A', 'Active'),
('C', 'Complete'),
('D', 'Development'),
)
TYPE_CHOICES = (
('A', 'Public'),
('B', 'Private'),
)
STATUS_DBS = (
('A', 'MySQL'),
('B', 'MS SQL'),
)
STATUS_OS = (
('A', 'Linux'),
('B', 'OS X'),
('C', 'Unix'),
('D', 'Windows'),
)
STATUS_LANG = (
('A', 'English'),
)
STATUS_ENC = (
('A', 'Autodetect'),
('B', 'Utf8 (UTF-8 unicode)'),
('C', 'ISO Latin 1 (latin1)'),
)
name = models.CharField(max_length=50)
client = models.ForeignKey(User)
gen_source_path = models.CharField(max_length=100)
gen_dest_path = models.CharField(max_length=100)
url = models.CharField(max_length=100, blank=True)
db_type = models.CharField(max_length=1, choices=STATUS_DBS)
db_name = models.CharField(max_length=50)
table_name = models.CharField(max_length=50)
cookie_name = models.CharField(max_length=50)
header_title1 = models.CharField(max_length=50)
header_title2 = models.CharField(max_length=50)
header_title3 = models.CharField(max_length=50)
footer_title1 = models.CharField(max_length=50)
footer_title2 = models.CharField(max_length=50)
status = models.CharField(max_length=1, choices=STATUS_CHOICES)
survey_type = models.CharField(max_length=1, choices=TYPE_CHOICES)
operating_system = models.CharField(max_length=1, choices=STATUS_OS)
language = models.CharField(max_length=1, choices=STATUS_LANG)
encoding = models.CharField(max_length=1, choices=STATUS_ENC)
def __unicode__(self):
return self.name
def client_name(self):
return str(self.client.user)
class Meta:
ordering = ["name"]
and this is the form:
class SurveyForm(forms.ModelForm):
"""Highest level class that defines the attriutes of a survey"""
STATUS_CHOICES = (
('A', 'Active'),
('C', 'Complete'),
('D', 'Development'),
)
TYPE_CHOICES = (
('A', 'Public'),
('B', 'Private'),
)
STATUS_DBS = (
('A', 'MySQL'),
('B', 'MS SQL'),
)
STATUS_OS = (
('A', 'Linux'),
('B', 'OS X'),
('C', 'Unix'),
('D', 'Windows'),
)
STATUS_LANG = (
('A', 'English'),
)
STATUS_ENC = (
('A', 'Autodetect'),
('B', 'Utf8 (UTF-8 unicode)'),
('C', 'ISO Latin 1 (latin1)'),
)
name = forms.CharField(max_length=50, widget=forms.TextInput(attrs=
{'size':'50'}))
client = forms.ModelChoiceField(User.objects.all())
gen_source_path = forms.CharField(max_length=100,
widget=forms.TextInput(attrs={'size':'50'}))
gen_dest_path = forms.CharField(max_length=100 ,widget=forms.TextInput
(attrs={'size':'50'}))
url = forms.CharField(max_length=100, required=False,
widget=forms.TextInput(attrs={'size':'50'}))
db_type = forms.CharField(max_length=1, widget=forms.Select
(choices=STATUS_DBS))
db_name = forms.CharField(max_length=50 ,widget=forms.TextInput(attrs=
{'size':'50'}))
table_name = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
cookie_name = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
header_title1 = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
header_title2 = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
header_title3 = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
footer_title1 = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
footer_title2 = forms.CharField(max_length=50 ,widget=forms.TextInput
(attrs={'size':'50'}))
status = forms.CharField(max_length=1, widget=forms.Select
(choices=STATUS_CHOICES))
survey_type = forms.CharField(max_length=1, widget=forms.Select
(choices=TYPE_CHOICES))
operating_system = forms.CharField(max_length=1, widget=forms.Select
(choices=STATUS_OS))
language = forms.CharField(max_length=1, widget=forms.Select
(choices=STATUS_LANG))
encoding = forms.CharField(max_length=1, widget=forms.Select
(choices=STATUS_ENC))
I tried commenting out the foreign key to the user but that made no
difference. I must be doing something stupid here (obvious hopefully).
Can anyone tell me what the problem is?
Thanks,
Peter
