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

I'm trying to retrieve data from user. The form where i want to show the user information is also the same that i use to update this information.
Update3
After some updates I make this work and this is my code. If somenone have a better way to do this can share it :)
models.py
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class informacionFacturacion(models.Model):
usuario = models.ForeignKey(User, on_delete=models.CASCADE)
apellidos = models.CharField(max_length=100)
nombres = models.CharField(max_length=100)
[More fields...]
def __str__(self):
self.apellidos
forms.py
from .models import informacionFacturacion
#Create your forms here.
class informacionFacturacionForm(ModelForm):
class Meta:
model = informacionFacturacion
fields = [
"usuario",
"apellidos",
"nombres",
[More fields...]
]
views.py
#login_required
def datosPersonales(request):
#Filter query by user ID
query = informacionFacturacion.objects.filter(usuario=request.user)
form = informacionFacturacionForm()
#If query has content, edit record, else, create a new record
if query:
if request.method == "POST":
form = informacionFacturacionForm(request.POST or None, instance=query[0])
if form.is_valid():
edit_content = form.save()
edit_content.save()
else:
if request.method == "POST":
form = informacionFacturacionForm(request.POST)
if form.is_valid():
create_content = form.save(commit=False)
create_content.save()
return HttpResponseRedirect(reverse('datosPersonales'))
context = {
"titulo": "Datos personales | Co.",
"body_class": "class= sidebar_main_open sidebar_main_swipe",
"form": form,
"infoFacturacion": query,
}
template = "micuenta/datosPersonales.html"
return render(request, template, context)
Thanks for the support.
At first glance, it seems that the informacionFacturacion table is not being populated. Have you checked that the instance.save() is reached? (in other words, that the form is valid)
Second, in the template you want to use the informacionFacturacion object as the form elements, and you are handling them separately. Do:
if request.POST:
form = informacionFacturacionForm(request.POST)
if form.is_valid():
instance = form.save(commit=False)
instance.save()
else:
# handle here the form error's, maybe report it in the template
else:
query = informacionFacturacion.objects.filter(usuario=request.user)
form = informacionFacturacionForm(instance=query[0])
and render the form parameter insead of infoFacturacion:
{{ form.as_p }}
finally, make sure that your template form id's matches the form element names, otherwise the form won't be filled.
UPDATE
Based on your edit, now the error is in this line:
form = informacionFacturacionForm(request.POST, instance=query_id)
query_id is an int, and it is expecting a model. Change the following line:
query_id = informacionFacturacion.objects.get(usuario=request.user).id
to
query = informacionFacturacion.objects.get(usuario=request.user)
and the faulty line to:
form = informacionFacturacionForm(request.POST, instance=query)
that should work for now, although code can be simplified a lot.
EDIT 2
Here is what I assume you want:
#login_required
def datosPersonales(request):
query = informacionFacturacion.objects.filter(usuario=request.user)
if request.method == "POST": # This will handle the template form's POST
form = informacionFacturacionForm(request.POST)
if form.is_valid():
asd = form.save(commit=False)
asd.save()
# Here you may want to redirect to somewhere else
# Im not sure here, I guess that you want to handle the GET method if
# there is no form in the request. Post your template form to see what
# is happening.
else:
form = informacionFacturacionForm(instance=query)
# you dont need to save it, it is already in DB
context = {
"titulo": "Datos personales | Co.",
"body_class": "class= sidebar_main_open sidebar_main_swipe",
# I think here is your main issue, you are handling a form object
# AND a infoFacturacion object. You need to use just the
# form object in the template and render it accordingly.
"form": form,
"infoFacturacion": query,
}
template = "micuenta/datosPersonales.html"
return render(request, template, context)
Well, I was with the same problem on my sytem, so I made this solution, maybe it works to you! =D
I'm changing the value of the submit button and using the same form:
<button type="submit" id="submitButton" name="button" value="">Save</button>
If is a new task, I change the value of the button with JQuery:
$('#submitButton').val('new');
And if is an edition, I change the value again:
$('#submitButton').val('edit');
On my views.py, I check if is an edit or a new save by the value of the button:
def index(request):
tasks = Task.object.filter()
context = {
'tasks': tasks
}
if request.method == 'POST':
form = NewTask(request.POST or None)
if request.POST['button'] == 'new':
if form.is_valid():
context['is_valid'] = True
form.save()
form = NewTask()
else:
context['is_valid'] = False
if request.POST['button'] == 'edit':
instance = Task.object.filter(pk=request.POST['id']).first()
form = NewTask(request.POST, instance=instance)
if form.is_valid():
context['is_valid'] = True
form.save()
else:
context['is_valid'] = False
else:
form = NewTask()
context['form'] = form
return render(request, 'index.html', context)
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 am a real beginner in web development. The following code is failing at the is_valid() check. But I do not understand why: The form should get its data filled from the POST-data or not?
Model:
class Statement(models.Model):
text = models.CharField(max_length=255)
user = models.ForeignKey(User)
time = models.DateField()
views = models.IntegerField()
ModelForm:
class StatementForm(ModelForm):
class Meta:
model = Statement
widgets = {
'time':forms.HiddenInput(),
'user':forms.HiddenInput(),
'views':forms.HiddenInput(),
}
View function:
def new(request):
if request.method == 'POST': # If the form has been submitted...
form = StatementForm(request.POST) # A form bound to the POST data
if form.is_valid():
stmt = form.save()
path = 'stmt/' + stmt.id
return render_to_response(path, {'stmt': stmt})
else:
c = {}
c.update(csrf(request))
loggedin_user = request.user
d = datetime.now()
form = StatementForm(request.POST, initial={'time': d.strftime("%Y-%m-%d %H:%M:%S"), 'user':loggedin_user, 'views':0})
return render_to_response('new_stmt.html', {'form': form, },context_instance=RequestContext(request))
I found similar topics and tried a lot. This is how i think it should work. I really need advice.
All fields of your model are required. So, form.is_valid() will be True, if all fields are filled with correct values and are not blanked.
You have declared fields time, user, views as hidden fields. Are you sure, that you have filled them in your template form?
Also, you may want to auto stamp field time = models.DateField(). Modify your model field like
time = models.DateField(auto_now=True)`.
After this you don't have to fill it by yourself in template form.
Your view must return HttpResponse object in all cases. If your form is not valid, i.e. if form.is_valid() will return False, then no HttpResponse object will be returned by your view. This can be the source of your fail. Add else statement for if form.is_valid():
from django.http import Http404
def new(request):
if request.method == 'POST': # If the form has been submitted...
form = StatementForm(request.POST) # A form bound to the POST data
if form.is_valid():
stmt = form.save()
path = 'stmt/' + stmt.id
return render_to_response(path, {'stmt': stmt})
else:
# Do something in case if form is not valid
raise Http404
else:
# Your code without changes
Change this line:
form = StatementForm(request.POST, initial={'time': d.strftime("%Y-%m-%d %H:%M:%S"), 'user':loggedin_user, 'views':0})
For this:
form = StatementForm(initial={'time': d.strftime("%Y-%m-%d %H:%M:%S"), 'user':loggedin_user, 'views':0})
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
I'm trying to update an object, but I'm getting: "primary key must be unique"... The model for Entry:
class Entry(models.Model):
title = models.CharField(max_length=250)
author = models.ForeignKey(User, editable=False)
status = models.IntegerField(choices=data_types.STATUS_CHOICES,
default = data_types.STATUS_DRAFT)
And the view:
#login_required
def edit_entry(request, entry_id='0'):
message = ""
entry = get_object_or_404(Entry.objects, pk=entry_id)
if request.method == 'GET':
form = EntryForm(instance=entry)
else :
if request.method == 'POST':
if request.POST['submit'] == 'Edit':
print "entry id: %s" % entry.id
form = EntryForm(request.POST, instance=entry)
if form.is_valid():
secondEntry = form.save(False)
print "second entry id: %s" % secondEntry.id
form.save()
message = "entry updated"
else:
message = 'There were errors'
return render_to_response(
'myadmin/edit_entry.html',
{ 'entryForm':form,'message': message},
context_instance=RequestContext(request))
So I print both IDs and they are the same: 1. That should make form.save() update the object, but instead, it tries to insert it... any idea?
Well maybe in the line
form = EntryForm(request.POST, instance=entry)
you dont specify an intance parameter, because this is for update an existing model....
Your first form.save(False) produces an Entry object filled with the data from the form, so you should save that Entry object instead of the form again.
secondEntry = form.save(commit=False)
secondEntry.save()
Why do you have form.save() twice? Perhaps that is the problem.
form.save(force_update=True)
