I have difficulty saving my form into db. Every time I click on save it didn't save in db/admin. Can't seem to figure it out. I hope somebody out there can help me with this.
This project is about collecting information on a new customer for a construction company and if the customer exist in the db then it will view the detail of the particular customer and be able to edit the particular customer when needed and be able to overwrite the data when save. This information gather from a customer model and building model and customerForm and buildingForm and display in customer template.
models.py
class customer(models.Model)
F_NAME = models.CharField(max_length = 50)
L_NAME = models.CharField(max_length = 50)
ADD = models.CharField(max_length = 60, blank =True)
EMAIL = models.EmailField()
def __unicode__(self):
return '%s' % ( self.F_NAME )
class building(models.Model):
CUSTOMER = models.ForeignKey(customer)
B_USE = models.CharField(max_length = 2, blank = True, choices = c.Use)
B_FLOORSPACE = models.IntegerField(default=0)
B_YEAR = models.IntegerField(null = True, blank = True)
B_TYPE = models.CharField(max_length = 2, blank = True, choices = c.Type)
def __unicode__(self):
return '%s' % (self.B_USE)
forms.py
class customerForm(ModelForm):
F_NAME = forms.CharField(widget=forms.TextInput(attrs={'size':'34'}))
L_NAME = forms.CharField(widget=forms.TextInput(attrs={'size':'34'}))
EMAIL = forms.CharField(widget=forms.TextInput(attrs={'size':'19'}))
ADD = forms.CharField(widget=forms.TextInput(attrs={'size':'34'}))
class Meta:
model = customer
class buildingForm(ModelForm):
CUSTOMER = forms.CharField(widget=forms.TextInput(attrs={'size':'20'}))
B_FLOORSPACE = forms.CharField(widget=forms.TextInput(attrs={'size':'4'}))
B_YEAR = forms.CharField(widget=forms.TextInput(attrs={'size':'4'}))
class Meta:
model = building
exclude = ('CUSTOMER',)
widgets = {'B_USE' : RadioSelectNotNull(),
'B_TYPE' : RadioSelectNotNull(),
}

I have try this demo on multiple model entry in single form http://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ and Django: multiple models in one template using forms and How to use two different Django Form at the same template? but can't see where the mistake is. My task is quite simple for now, I just have to save all the information that has been keyed-in and saved in the database.
