I'm just starting to use django and have run into a problem I have not
been able to solve.
I have a model Item which stores, among other things, user_id.
Then I have a ModelForm. I want user_id to be a hidden field. After
searching around the web, I found out how to create a hidden field.
The template is rendered as I like it.
user_id is a hidden field with a value of 1. The problem is when I
submit the form, I get IntegrityError. "Column 'user_id' cannot be
null".
but from the debug message I get back I can see that POST has all 3
things I need. So maybe when a new form is created there is problem.
views.py
@login_required
def newItem(request):
if not request.POST:
form = ItemForm()
return render_to_response('manager/newItem.html',{'form':form})
newForm = ItemForm(request.POST)
if newForm.is_valid():
newForm.save() #problem here?
return HttpResponsePermanentRedirect('.')
models.py
class Item(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=32)
description = models.CharField(max_length=128)
creation_date = models.DateField(auto_now=True)
forms.py
class ItemForm(ModelForm):
user_id_wid = forms.HiddenInput(attrs={'value': 1})
user_id = forms.IntegerField(widget=user_id_wid,required=False)
class Meta:
model = Item
fields = ['name', 'description']
and my template has:
<form action="newItem" method="POST">
<fieldset>
<legend>Create Item</legend>
{% for field in form %}
{% if field.is_hidden %}
{{field}}
{% else %}
<div class="fieldWrapper">
{{ field.errors }}
{{ field.label_tag }}: {{ field }}
</div>
{% endif %}
{% endfor %}
<p><input type="submit" value="create"></p>
</fieldset>
</form>
The hidden field is not being bound to the form? is that it? If so how
can I go about it?
NOTE: I can insert a new object if i manually create a form myself,
and just get the values from request.POST and do Item.objects.create()
with the POST values I get. I am just learning so I want to make sure
how to do this with ModelForms. That way i won't have to write as many
forms html either.
Thanks!
