How to commit ManyToManyField with ModelForm

2010-07-09 Thread yugori 
Hi, I'm beginner of Django
Now I try to make Product Management Tool with Django.
So I wrote some code.

models.py
//---
from django import forms
from django.db import models

# ex('ie8','InternetExplorer8')
class Browser(models.Model):
  id=model.CharField('id',primary_key=True)
  name=model.CharField('name')

  def __unicode__(self):
return self.name

# ex('iphone3','iPhoneOS3')
class Device(models.Model):
  id=model.CharField('id',primary_key=True)
  name=model.CharField('name')

  def __unicode__(self):
return self.name

# ex('site01','MySite','browser[]','device[]')
class Product(models.Model):
  id = models.CharField('id', primary_key=True)
  name = models.CharField('name')
  support_browser = models.ManyToManyField(Browser)
  support_device = models.ManyToManyField(Device)

  def __unicode__(self):
return self.name

class ProductForm(forms.ModelForm):
  class Meta:
model = Product
---//


view.py
//---
def create(request):
if request.method == 'POST':
form = ProductForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/product/detail/'+form.id
+'/')
else:
print form.errors
errors = form.errors
return render_to_response('Product/create.html',{'errors':
errors,'form':form})

else:
form = ProductForm()

return render_to_response('Product/create.html',{'form':form})
---//


create.html
//---

create


{{ form.errors }}

  ID{{form.id}}


  NAME{{form.name}}


  Support Browser
  {{form.support_browser}}


  Support Device
  {{form.support_device}}

  




---//



1.Access to /product/create/ - it works good!
2.Complete form and submit - it works good!
3.Watch table 'product' - it works good? There's no column
'support_browser' and 'support_device'.
4.Watch intermidieval table 'product_browser'(autogenerated) - it has
no rows...

What's wrong?
Please tell me..

Re: models.py import from other models.py

2010-07-08 Thread yugori 
This problem is resolved.

What I did is
1.comment out "models.ManyToManyField" line and execute "manage.py
syncDB".
2.Back to code "models.ManyToManyField" line and execute "manage.py
evolve --hint --execute"
Then appli_master table was auto-generated.

I don't know why this way goes right.

But, now I have another problem.

I use ModelForm to deal the table, I try to submit and form.save()
then the data column is added Appli table successfully, but
appli_master table has no updated data.

orz..

models.py import from other models.py

2010-07-07 Thread yugori 
Hi, I'm beginner.

I tried to execute 'manage.py syncDB' command,
but it's not work.

My package is like ..

MyProjectMaster---models.py
|  Appli-models.py


MyProject/Appli/models.py is ..
//-
from Master.models import WebBrowser

class Appli(models.Model):
# id
id = models.CharField(u'id', max_length=20, blank=False,
primary_key=True)
# support_browser
support_browser = models.ManyToManyField(WebBrowser,blank=True)

def __unicode__(self):
return self.name
//

I tried that with comment out import from above code,it's work.

Is this bad design?

I wish to anyone help me.
