i want to save data in two table mysql, that was nice, but now i change a field form Interget to FK.. the problem is that now i cant send the data to the field FK....
im new with Django, but im working in this way:
#login_required
def agregar_diligencia(request):
if request.method =='POST':
form = DiligenciaForm(request.POST)
#trac = Tracking()
tracknum = 'ABCD458LK'
if form.is_valid():
from django.contrib.auth.models import User
User = User.objects.get(pk=request.user.id)
obj = form.save(commit=False)
obj.socio = User
obj.status = 0
obj.secuencia = 1
obj.save()
t = Tracking()
t.track = tracknum
t.diligencia = obj.id
t.save()
return HttpResponseRedirect('/accounts/diligencias/activas')
else:
form = DiligenciaForm()
return render_to_response('account/agregar_diligencia_form.html',
{ 'formulario':form },context_instance = RequestContext(request))
Where t.diligencia = obj.id (t.diligencia) is my FK and obj.id is the data that i want to save in the FK
Sorry with my English and thanks.
You haven't at all stated what the problem is.
However one thing that I can see is that you're overwriting User in this line:
User = User.objects.get(pk=request.user.id)
You should be assigning to user with a lower-case u - but I doubt that's the source of your problem, whatever it is.
just do
obj.socio = request.user

this is my first post here and I am very new to Django but I just can't seem to find a solution for this problem... I've searched stackoverflow and google but nothing seems to work for me...
I have a wine-app and want to be able to add and remove wines from the user's stock. In the list of wines the user can choose a wine to add and the ID of this wine is passed in the POST data. Since the data is getting lost after the first time the view is rendered I saved the ID in a cookie, which is working, but the problem is when I work with ModelForm de user has to select the foreign key for the user and for the wine, which is bad, so I tried to make it hidden and set the Fk_user and Fk_wine after the user choose the number of bottles to be added but before validation. Here's the problem after google everyone suggested I should use the "initial" and pass that to the form, but this is clearly not working because if I make the fields visible in the form I can see that it is not preselected...
viewy.py:
def addStockView(request):
wineId = request.POST.get('addStock')
if 'addStock' in request.POST:
wine = get_object_or_404(Wine, idwine=int(wineId))
userId = request.user.id
user = get_object_or_404(AuthUser, id=userId)
if request.method == 'POST':
#wineIdNew = request.COOKIES.get('wineIdToAdd')
#wineNew = get_object_or_404(Wine, idwine=wineIdNew)
form = StockForm(request.POST, initial={'fk_wine': wineNew.idwine, 'fk_auth_user': user.id})
if form.is_valid():
form.save()
return redirect('home')
else:
form = StockForm(initial={'fk_wine': wine.id,
'fk_auth_user': user.id})
response = render(request, 'addToStock.html', {'form': form})
response.set_cookie('wineIdToAdd', wineId)
return response
forms.py:
class StockForm(forms.ModelForm):
#fk_wine = ModelChoiceField(queryset=Wine.objects.all(),
# widget=HiddenInput())
#fk_auth_user = ModelChoiceField(queryset=AuthUser.objects.all(),
# widget=HiddenInput())
class Meta:
model = UserWineStock
fields = ['fk_auth_user', 'fk_wine', 'number']
can anyone help me with this..?
Yes, initial data is ignored when a form is bound to submitted data.
Instead of using initial here, you should exclude those two fields from the form and set them on the created object:
form = StockForm(request.POST)
if form.is_valid():
item = form.save(commit=False)
item.fk_wine = wine
item.fk_auth_user = request.user
item.save()
return redirect('home')
(Also, please don't call your fields things like fk_auth_user. Just call it user.)
with django 1.5.1 I try to use the django form for one of my models.
I dont want to add the "user" field (Foreignkey) somewhere in the code instead of letting the user deceide whoes new character it is.
My Code:
Model:
class Character(models.Model):
user = models.ForeignKey(User)
creation = models.DateTimeField(auto_now_add=True, verbose_name='Creation Date')
name = models.CharField(max_length=32)
portrait = models.ForeignKey(Portrait)
faction = models.ForeignKey(Faction)
origin = models.ForeignKey(Origin)
The form:
class CreateCharacterForm(forms.ModelForm):
class Meta:
model = Character
fields = ['name', 'portrait', 'faction', 'origin']
The view:
def create_character(request, user_id):
user = User.objects.get(id=user_id)
if request.POST:
new_char_form = CreateCharacterForm(request.POST)
if new_char_form.is_valid():
new_char_form.save()
return HttpResponseRedirect('%s/characters/' % user_id)
else:
return render_to_response('create.html',
{'user': user, 'create_char':new_char_form},
context_instance=RequestContext(request))
else:
create_char = CreateCharacterForm
return render_to_response('create.html',
{'user': user, 'create_char': create_char},
context_instance=RequestContext(request))
I have tried to use a instance to incluse the userid already. i've tried to save the userid to the form before saving it, or changing the save() from my form.
I keep getting the error that character.user cant be null
I have to tell that im pretty new to django and im sure one way or another it should be possible
Can someone please help me out?
Its explained well in document model form selecting fields to use
You have to do something like this in your view
...
if request.POST:
new_char_form = CreateCharacterForm(request.POST)
if new_char_form.is_valid():
#save form with commit=False
new_char_obj = new_char_form.save(commit=False)
#set user and save
new_char_obj.user = user
new_char_obj.save()
return HttpResponseRedirect('%s/characters/' % user_id)
else:
...
This must be a very simple thing however I can not seem to get through it..
I trying to build a form where the user can update a ModelForm. First he inserts a user id and afterwards I want to show him the form pre-populate with the original data so he can change only the fields that he wants.
After some the help of my friend google, stackoverflow and the django documentation, I've come to this:
views.py
user = User.objects.get(user_id=usr)
if request.method == 'POST':
form = TableForm(request.POST)
if form.is_valid():
#do something
else:
form = TableForm(instance=user)
return render_to_response('template.html',{'form':form})
forms.py
class TableForm(forms.ModelForm):
pres_clinic = forms.ModelChoiceField(queryset=PresClinic.objects.all(),
widget=SelectWithPop(), label=ugettext("Clinic presentation"),
required=False)
MAYBECHOICES = (
('', '---------'),
(ugettext('Yes'), ugettext('Yes')),
(ugettext('No'), ugettext('No')))
bcg_scar = forms.ChoiceField(choices=MAYBECHOICES, label=ugettext(
"BCG scar"), required=False)
mantoux_register = forms.ChoiceField(choices=MAYBECHOICES,
label=ugettext("Mantoux register"), required=False)
date_diag = forms.DateField(widget=DateTimeWidget, label=ugettext(
"Diagnosis date"), required=False)
situation = forms.ModelChoiceField(queryset=Situation.objects.all(),
widget=SelectWithPop(), label=ugettext("Patient status"),
required=False)
date_situation = forms.DateField(widget=DateTimeWidget, label=ugettext(
"Date patient status"), required=False)
class Meta:
model = Table
fields = ('pres_clinic', 'bcg_scar', 'mantoux_register',
'date_diag', 'situation', 'date_situation')
def clean(self):
cleaned_data = self.cleaned_data
diag = cleaned_data.get('date_diag')
errors = []
now = datetime.date.today()
if diag is not None and diag != u'':
if diag > now:
errors.append(ugettext('The field "Diagnosis date" should be '
'smaller than the actual date'))
if errors:
raise ValidationError(errors)
return cleaned_data
template:
{{ form }} # presents the empty form and not the data from that user
The version of django is 1.4
Can anyone tell me what is wrong and why I'm not able to see the form populated?
Thank you very much
You need to define a dictionary to be used for the initial data and change from TableForm(instance=user) to TableForm(initial=dict), for example something like:
user = User.objects.get(user_id=usr)
if request.method == 'POST':
form = TableForm(request.POST)
if form.is_valid():
#do something
else:
data = {'pres_clinic' : 'value', 'bcg_scar' : 'value', 'mantoux_register' : 'value'}
form = TableForm(initial=data)
return render_to_response('template.html',{'form':form})
I would also put the render to response out of the if statement so if the form isn't valid the page should reload and show any errors.
More information on the django docs here
I hope this helps!
You can try 'model_to_dict'
from django.forms.models import model_to_dict
user = User.objects.get(user_id=usr)
if request.method == 'POST':
form = TableForm(request.POST)
if form.is_valid():
#do something
else:
form = TableForm(initial=model_to_dict(user))
return render_to_response('template.html',{'form':form})
I have settings form page. If user filled the form once; it must display those values. But if there is no data [first time] I get query error. I need that query, because the form data must be written as related with current user [logged in].
here is my view part :
#login_required(login_url='/login/')
def profile_page(request,username):
query = Profile.objects.get(owner__username = username) ##error!
if request.method == 'POST':
form = profile_form(request.POST,instance=query)
form.save()
return HttpResponseRedirect('/admin/')
else:
form = profile_form(instance=query)
return render_to_response('profile_save.html',{'form':form},context_instance = RequestContext(request))
I think I need to check the model and if it is empty I should do something different.
I am stuck.
Thank you
You want to make use of the .exists() queryset option
#login_required(login_url='/login/')
def profile_page(request,username):
form = profile_form()
if Profile.objects.get(owner__username = username).exists():
query = Profile.objects.get(owner__username = username)
if request.method == 'POST':
form = profile_form(request.POST,instance=query)
form.save()
return HttpResponseRedirect('/admin/')
else:
form = profile_form(instance=query)
return render_to_response('profile_save.html',{'form':form},context_instance = RequestContext(request))
see QuerytSet API reference for more information
You just need to wrap that get query in try ... except and set instance to none, like this.
from django.core.exceptions import ObjectDoesNotExist
#login_required(login_url='/login/')
def profile_page(request,username):
try:
query = Profile.objects.get(owner__username = username)
#to be more specific you can except ProfileObjectDoesNotExist
except ObjectDoesNotExist:
query = None #Doesn't exist, set to None
if request.method == 'POST':
form = profile_form(request.POST,instance=query)
form.save()
return HttpResponseRedirect('/admin/')
else:
form = profile_form(instance=query)
return render_to_response('profile_save.html',{'form':form},
context_instance = RequestContext(request))
I think i may have use get_or_create for this purpose.
Profile.objects.get_or_create(owner__username = username)
I have an object Task and a form that saves it. I want to automatically asign created_by field to the currently logged in user. So, my view is this:
def new_task(request, task_id=None):
message = None
if task_id is not None:
task = Task.objects.get(pk=task_id)
message = 'TaskOK'
submit = 'Update'
else:
task = Task(created_by = GPUser(user=request.user))
submit = 'Create'
if request.method == 'POST': # If the form has been submitted...
form = TaskForm(request.POST, instance=task)
if form.is_valid():
task = form.save(commit=False);
task.created_by = GPUser(user=request.user)
task.save()
if message == None:
message = 'taskOK'
return tasks(request, message)
else:
form = TaskForm(instance=task)
return custom_render('user/new_task.html',
{'form': form, 'submit': submit, 'task_id':task.id},
request)
The problem is, you guessed, the created_by field doesn't get saved. Any ideas? Thanks
You are creating GPUser, but you don't save it. You must save it first, so it gets pk and only after that it can be assigned to a ForeignKey. Try this:
task.created_by = GPUser.object.create(user=request.user)
or
gpuser = GPUser(user=request.user)
gpuser.save()
task.created_by = gpuser
