I have a view defined like this. I'm getting error in making the user object extended to UserProfile and cannot user the user.id
Is the request.user authenticated? is it an AnonymousUser?
UserProfile.objects.get() method is not for creating an object but to get it from the database.
if it doesn't exist an exception will be raised.
use UserProfile.objects.create(..) with the initial data you may need for it.
hope this helps!
== edit ==
also, note that you are referring count_form in the RequestContext even when it wasn't initialized in case that the request.method was not "POST" (i.e. "GET")

I just wanna get profile with full form or empty form.
def local_cabinet(request):
user_id = request.user.id
caruser = Checkout.objects.filter(user=request.user)
# form = CheckoutForms()
orders = request.user.orderitem_set.all()
total_orders = orders.count()
ready_order = request.user.order_set.all()
customer = Customer.objects.filter(user=request.user)
customer_form = CustomerForm()
Maybe here's problem I don't know:
if request.method == 'POST':
if customer.exists():
form = CustomerForm(request.POST, request.FILES, instance=customer)
else:
form = CustomerForm(request.POST)
if form.is_valid():
form.save()
context = {
'caruser': caruser,
'orders': orders,
'total_orders': total_orders,
'ready_order': ready_order,
'cat_selected': 0,
'customer_form': customer_form,
'customer': customer,
}
return render(request, 'localcabinet.html', context=context)
I don't know why I get this, maybe because I'm not right at saving the form.
You are missing User instance in form, that you probably need to pass it after form creation and before saving it.
You didn't provide model nor forms, but I guess it will look like this:
if request.method == 'POST':
...
else:
form = CustomerForm(request.POST)
form.user = request.user
if form.is_valid():
form.save()
...
Another thing is that you assign queryset instead of single object with filter method:
customer = Customer.objects.filter(user=request.user) # gives queryset with probably one object
customer = Customer.objects.get(user=request.user) # gives an object - but gives Error if there is None or more than one
Probably the best approach to get single object is with try and except:
try:
customer = Customer.objects.get(user=request.user)
except Customer.DoesNotExists:
customer = None
then later instead of if customer.exists() you can use simple if customer.
This is the code I have, and when I run it on Django, I am met with this error: 'Title' object has no attribute cleaned_data
def new(request):
form = Title(request.POST)
if request.method == "POST":
if form.is_valid:
title = form.cleaned_data["title"]
text = form.cleaned_data["text"]
util.save_entry(title, text)
else:
return render(request, "encyclopedia/error.html",{
"form":NewForm()
})
return redirect(reverse('page', args = [title]))
return render(request, "encyclopedia/newpage.html",{
"form1":Title(),
"form": NewForm()
})
You are probably getting the exception thrown in your return statement where you are instantiating a new Title object. This object only gets the cleaned_data attribute when is_valid method has been called upon. Hence you haven't called this on the new Title object and that is the reason why you are getting the error.
you use form = Title(request.POST), but the line after you check whether the request.method equals POST or not. i think yo should move that line inside the if statement
is_valid() it's a function
def new(request):
form = Title(request.POST)
if request.method == "POST":
if form.is_valid():
title = form.cleaned_data["title"]
text = form.cleaned_data["text"]
util.save_entry(title, text)
else:
return render(request, "encyclopedia/error.html",{
"form":NewForm()
})
return redirect(reverse('page', args = [title]))
return render(request, "encyclopedia/newpage.html",{
"form1":Title(),
"form": NewForm()
})
I currently have a model form that submits an entered domain to the db.
The problem I'm encountering is, I need to save the currently logged in user's ID (PK from the django.auth table) when a domain is submitted to satisfy a PK-FK relationship on the db end.
I currently have:
class SubmitDomain(ModelForm):
domainNm = forms.CharField(initial=u'Enter your domain', label='')
FKtoClient = User.<something>
class Meta:
model = Tld #Create form based off Model for Tld
fields = ['domainNm']
def clean_domainNm(self):
cleanedDomainName = self.cleaned_data.get('domainNm')
if Tld.objects.filter(domainNm=cleanedDomainName).exists():
errorMsg = u"Sorry that domain is not available."
raise ValidationError(errorMsg)
else:
return cleanedDomainName
and views.py
def AccountHome(request):
if request.user.is_anonymous():
return HttpResponseRedirect('/Login/')
form = SubmitDomain(request.POST or None) # A form bound to the POST data
if request.method == 'POST': # If the form has been submitted...
if form.is_valid(): # If form input passes initial validation...
domainNmCleaned = form.cleaned_data['domainNm'] ## clean data in dictionary
clientFKId = request.user.id
form.save() #save cleaned data to the db from dictionary`
try:
return HttpResponseRedirect('/Processscan/?domainNm=' + domainNmCleaned)
except:
raise ValidationError(('Invalid request'), code='300') ## [ TODO ]: add a custom error page here.
else:
form = SubmitDomain()
tld_set = request.user.tld_set.all()
return render(request, 'VA/account/accounthome.html', {
'tld_set':tld_set, 'form' : form
})
The problem is it gives me an error of: (1048, "Column 'FKtoClient_id' cannot be null"), very odd thing happening, for the column FKtoClient, its trying to submit: 7L instead of 7(the PK of this user's record). Any ideas?
If someone can please help, I would really appreciate it
Firstly, remove FKtoClient from your form. You need to set the user in your view where you can yes the request object. It's not possible to set an attribute on the form that automatically sets the current user.
When instantiating your form, you can pass a tld instance which already has the user set.
def AccountHome(request):
# I recommend using the login required decorator instead but this is ok
if request.user.is_anonymous():
return HttpResponseRedirect('/Login/')
# create a tld instance for the form, with the user set
tld = Tld(FKtoClient=request.user)
form = SubmitDomain(data=request.POST or None, instance=tld) # A form bound to the POST data, using the tld instance
if request.method == 'POST': # If the form has been submitted...
if form.is_valid(): # If form input passes initial validation...
domainNm = form.cleaned_data['domainNm']
form.save() #save cleaned data to the db from dictionary
# don't use a try..except block here, it shouldn't raise an exception
return HttpResponseRedirect('/Processscan/?domainNm=%s' % domainNm)
# No need to create another form here, because you are using the request.POST or None trick
# else:
# form = SubmitDomain()
tld_set = request.user.tld_set.all()
return render(request, 'VA/account/accounthome.html', {
'tld_set':tld_set, 'form' : form
})
This has an advantage over #dm03514's answer, which is that you can access the user within form methods as self.instance.user if required.
If you want to Require that a user be logged in to submit a form, you could do something like:
#login_required # if a user iS REQUIRED to be logged in to save a form
def your_view(request):
form = SubmitDomain(request.POST)
if form.is_valid():
new_submit = form.save(commit=False)
new_submit.your_user_field = request.user
new_submit.save()
You can get the logged in user from the request object:
current_user = request.user
I want to create something similar as django admin changelist view with list_editable items...
I succeeded in creating the view. But when I post it dies on validation errors.
if request.POST:
formset_class = modelformset_factory(Job)
formset =formset_class(request.POST, request.FILES)
if formset.is_valid():
formset.save()
The problem is that I have only a couple of attributes editable. Therefore some of them are not part of POST and model complains about them being mandatory.
But I want to UPDATE objects not create them. Basically I really want the same thing admin does when having set list_editable but in my own view
I wanted a functionality just like admin using list_editable, so I went for it and pretty much copied the code from options.py of django source. I retrieved admin for my object and then saved original values (function fix_old_job_admin sets them back)
This code solved my problem
job_admin = admin.site._registry[Job]
# save old values so that you can go back to them later
old_list_display = job_admin.list_display
old_list_filter = job_admin.list_filter
old_ordering = job_admin.model._meta.ordering
job_admin.list_editable = ("time", "what", "approved")
cl = ChangeList(request, job_admin.model, job_admin.list_display, job_admin.list_display_links, job_admin.list_filter, job_admin.date_hierarchy, job_admin.search_fields, job_admin.list_select_related, job_admin.list_per_page, job_admin.list_editable,job_admin.admin_site, job_admin)
# options.py from django framework lines 1181-1208 (v. 1.4)
if request.POST:
FormSet = job_admin.get_changelist_formset(request)
formset =FormSet(request.POST, request.FILES, queryset=cl.result_list)
if formset.is_valid():
changecount = 0
for form in formset.forms:
if form.has_changed():
obj = job_admin.save_form(request, form, change=True)
job_admin.save_model(request, obj, form, change=True)
job_admin.save_related(request, form, formsets=[], change=True)
change_msg = job_admin.construct_change_message(request, form, None)
job_admin.log_change(request, obj, change_msg)
changecount += 1
if changecount:
if changecount == 1:
name = force_unicode(job_admin.model._meta.verbose_name)
else:
name = force_unicode(job_admin.model._meta.verbose_name_plural)
msg = ungettext("%(count)s %(name)s was changed successfully.",
"%(count)s %(name)s were changed successfully.",
changecount) % {'count': changecount,
'name': name,
'obj': force_unicode(obj)}
job_admin.message_user(request, msg)
# call function that sets admin with original values
fix_old_job_admin(job_admin, old_list_display, old_ordering, old_list_filter)
return HttpResponseRedirect(request.get_full_path())

please help me
That error means that 'book_name' isn't in your POST data.
If you want to handle that case, you can use book_name = request.POST.get('book_name'), which will default book_name to None if it isn't in the POST data.
If not, you need to make sure the form has an input called 'book_name'.
