Hello
I am new to django and try to use the ModelForm paradigma, but can't get the
point ;-((
My example:
models.py:
class Project(models.Model):
id = models.AutoField(primary_key=True)
deletetime = models.DateTimeField()
name = models.CharField(max_length=50)
beginDate = models.DateField()
endDate = models.DateField()
memo = models.TextField()
Doing:
project = Project()
project.save()
works fine (autofield increased, other fields empty)
forms.py:
class ProjectForm(ModelForm):
class Meta:
model = models.Project
- first try for empty record, expecting an empty Project-object to be created
from the form automatically:
projectForm = forms.ProjectForm()
projectForm.save()
=> result: 'ProjectForm' object has no attribute 'cleaned_data'
- second try for empty record by providing an empty Project-instance:
project = Project()
projectForm = forms.ProjectForm(instance=project)
projectForm.save()
=> result: 'ProjectForm' object has no attribute 'cleaned_data'
The _errors and errors attribute are present, but empty: {}
- first try to save an existing unmodified record:
project = Project.objects.get(id=1)
projectForm = forms.ProjectForm(instance=project)
project = projectForm.save()
=> result: 'ProjectForm' object has no attribute 'cleaned_data'
- second try to save an existing record with data from request.POST:
project = Project.objects.get(id=1)
projectForm = forms.ProjectForm(request.POST, instance=project)
project = projectForm.save()
The content of request.POST:
<QueryDict: {u'endDate': [u''], u'name': [u'Maissau'], u'memo': [u'aaa'], u'id':
[u'1'], u'savebutton': [u'savebutton'], u'beginDate': [u'2009-10-11']}>
=> result: The Project could not be changed because the data didn't validate.
Can anybody point me the right direction?
Thanks in advance
