i am saving a form with a filefield, and saying upload_to to a user_path from the userprofile. I do not know how to write the view for the form
models.py
def nice_user_folder_upload(instance, filename):
extension = filename.split(".")[-1]
return (
f"{instance.UserProfile.Assigned_Group}/{filename}"
)
class Metadataform(models.Model):
id = models.AutoField(primary_key=True)
Authors_Name = models.CharField(max_length=500, blank=True, null=True)
Document = models.FileField(upload_to=nice_user_folder_upload)
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
Assigned_Group= models.CharField(max_length=500, choices=Group_choices, default='Please Select')
def __str__(self):
return self.user.username
views.py
def Metadata_submission(request):
Authors_Name = request.POST["Authors_Name"]
if request.method == 'POST':
form = Fileuploadform(request.POST, request.FILES)
if form.is_valid():
form.save()
return render(request, "home.html")
else:
form = Fileuploadform()
# forms.py
class Fileuploadform(forms.ModelForm):
class Meta:
model = Metadataform
fields = ['Authors_Name','Affliations','Dataset_Creation_Date','Publication_Ref','Embargo_Time','DataGeneration_Type','Methods','Instruments','Software','Models','Device','Configuration','Precursor','Data_Type','Variables','Error_Estimation','Document']
class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ('Assigned_Group',)
i am getting an AttributeError at /Metadata_submission/
'Metadataform' object has no attribute 'UserProfile'
The problem here I think is you have so many fields here that might not be associated with your Metadataform model (Maybe you haven't posted it in full). I think you should consider reading doc. By the look of it, you are trying to add UserProfile somewhere on your form, which is causing the error.

I'm trying to display a form (ModelForm) with a select field filtered by currently logged in user. The select field in this case contains a list of categories. I want to display only the categories which "belong" to the currently logged in user. The category field is a foreign key to the IngredienceCategory model.
Here is what I've come up with so far but it's giving me an error (unexpected keyword queryset). Any ideas what I'm doing wrong?
# models.py
class IngredienceCategory(models.Model):
name = models.CharField(max_length=30)
user = models.ForeignKey(User, null=True, blank=True)
class Meta:
verbose_name_plural = "Ingredience Categories"
def __unicode__(self):
return self.name
class Ingredience(models.Model):
name = models.CharField(max_length=30)
user = models.ForeignKey(User, null=True, blank=True)
category = models.ForeignKey(IngredienceCategory, null=True, blank=True)
class Meta:
verbose_name_plural = "Ingredients"
def __unicode__(self):
return self.name
class IngredienceForm(ModelForm):
class Meta:
model = Ingredience
fields = ('name', 'category')
# views.py
def home(request):
if request.user.is_authenticated():
username = request.user.username
email = request.user.email
foods = Food.objects.filter(user=request.user).order_by('name')
ingredients = Ingredience.objects.filter(user=request.user).order_by('name')
ingrcat = IngredienceCategory.objects.filter(user=request.user)
if request.method == 'POST':
form = IngredienceForm(request.POST)
if form.is_valid():
# Create an instance of Ingredience without saving to the database
ingredience = form.save(commit=False)
ingredience.user = request.user
ingredience.save()
else:
# How to display form with 'category' select list filtered by current user?
form = IngredienceForm(queryset=IngredienceCategory.objects.filter(user=request.user))
context = {}
for i in ingredients:
context[i.category.name.lower()] = context.get(i.category.name.lower(), []) + [i]
context2 = {'username': username, 'email': email, 'foods': foods, 'ingrcat': ingrcat, 'form': form,}
context = dict(context.items() + context2.items())
else:
context = {}
return render_to_response('home.html', context, context_instance=RequestContext(request))
That's happening because ModelForm does not take a queryset keyword.
You can probably achieve this by setting the queryset on the view:
form = IngredienceForm()
form.fields["category"].queryset =
IngredienceCategory.objects.filter(user=request.user)
See related question here.
Here i have another suggestion to solve the problem. You can pass request object in your form object inside view.
In view.py just pass the request object.
form = IngredienceForm(request)
In your forms.py __init__ function also add request object
from models import IngredienceCategory as IC
class IngredienceForm(ModelForm):
class Meta:
model = Ingredience
fields = ('name', 'category')
def __init__(self, request, *args, **kwargs):
super(IngredienceForm, self).__init__(*args, **kwargs)
self.fields['name'].queryset = IC.objects.filter(user=request.user)
This filter always will be applied whenever you initialize your form .
I'm new in Django and I'm trying to pre fill one of the fields of my form with a slug.
I'm getting the slug from another model. I'm not using ForeignKey because that shows me a list with my objects and I want to save in the form the same slug that I'm using in the url.
Maybe I'm not thinking this right. What should I do?
Thank you!
This are my models:
from django.db import models
class Thing(models.Model):
name = models.CharField(max_length=255,)
rut = models.CharField(max_length=12, blank= True)
cel = models.CharField(max_length=12, blank= True)
slug = models.SlugField(unique=True)
class Control(models.Model):
id_p = models.SlugField()
pa = models.CharField(max_length=3,)
My forms
from django.forms import ModelForm
from collection.models import Thing, Control, Medicamento
class ThingForm(ModelForm):
class Meta:
model = Thing
fields = ('name', 'rut','cel','pet',)
class ControlForm(ModelForm):
class Meta:
model = Control
exclude = ['id_p']
This is what I'm doing in the views
def add_control(request, slug):
thing = Thing.objects.get(slug=slug)
form_class = ControlForm
form_class(initial={'id_p':thing})
if request.method == 'POST':
form = form_class(request.POST)
if form.is_valid():
form.save()
return redirect('thing_detail', slug=thing.slug)
else: form = form_class()
return render(request, 'things/control.html', {
'thing': thing,
'form': form,
})
So, I figure it out!
In views.py, after " if form.is_valid():"
I put this:
prev = form.save(commit=False)
prev.id_p = thing.slug
prev.save()
In that way I put the data in the excluded field before I commit the form.

This is probably a fairly simple question, but I can't seem to figure it out from the Django Docs. I'm trying to save a two ModelForms at once with one being a ForeignKey of another. I'm not sure how to write the logic in the views to ensure these go together properly.
models.py
class Address(models.Model):
address = models.CharField(max_length=100)
city = models.CharField(max_length=50)
zipcode = models.PositiveIntegerField()
class Store(models.Model):
name = models.CharField(max_length=100)
description = models.CharField(max_length=140, blank=True)
address = models.ForeignKey(Address, null=True)
forms.py
class CreateStore1Form(forms.ModelForm):
class Meta:
model = Store
exclude = ('address',)
class CreateStore2Form(forms.ModelForm):
class Meta:
model = Address
views.py
#login_required
def create(request):
if request.method == "POST":
form1 = CreateStore1Form(request.POST)
form2 = CreateStore2Form(request.POST)
if form1.is_valid() and form2.is_valid():
store = form1.save(address)
new_address = form2.save(commit=False)
new_address.store = store
mew_address.save()
else:
form1 = CreateStore1Form()
form2 = CreateStore2Form()
return render(request, 'create.html', locals())
Any help would be appreciated. Thanks!
Django provides inline formsets for this use case:
Inline formsets is a small abstraction layer on top of model formsets.
These simplify the case of working with related objects via a foreign
key.
forms.py
class AddressForm(forms.ModelForm):
class Meta:
model = Address
class StoreForm(forms.ModelForm):
class Meta:
model = Store
exclude = ('address',)
views.py
from django.forms.models import inlineformset_factory
#login_required
def create(request):
AddressInlineFormSet = inlineformset_factory(Address, Store, form=AddressForm)
if request.method == 'POST':
storeForm = StoreForm(request.POST)
if storeForm.is_valid():
new_store = storeForm.save()
addressInlineFormSet = AddressInlineFormSet(request.POST, request.FILES, instance=new_store)
if addressInlineFormSet.is_valid():
addressInlineFormSet.save()
return HttpResponseRedirect(reverse('some_happy_customer_url'))
else:
classificationformset = ClassificationInlineFormSet(request.POST, request.FILES, instance=new_store)
else:
addressInlineFormSet = AddressInlineFormSet()
storeForm = StoreForm()
return render(request, 'create.html', locals())

I have a form from my model that needs to be validated and saved making use of ManyToMany Fields.
Everytime I try and save it, I get thrown back to the page, just saying this field is required
My models.py
class HuntingReport(models.Model):
user = models.ForeignKey(User, related_name='User')
outfitter = models.ForeignKey(User, related_name='Outfitter', null=True, blank=True)
date_travel_started = models.DateField(blank=True, null=True)
date_travel_ended = models.DateField(null=True, blank=True)
title = models.CharField(max_length=50)
report = models.TextField()
wish_list = models.ManyToManyField(Specie)
bag_list = models.ManyToManyField(Trophies)
def __unicode__(self):
return self.title
My forms.py looks as follows
class HuntingReportForm(ModelForm):
date_travel_started = forms.DateField(widget=extras.SelectDateWidget(years=range(1970,2010)))
date_travel_ended = forms.DateField(widget=extras.SelectDateWidget(years=range(1970,2010)))
wish_list = forms.ModelMultipleChoiceField(queryset=Specie.objects.all(), widget=FilteredSelectMultiple("verbose name", is_stacked=False))
bag_list = forms.ModelMultipleChoiceField(queryset=Trophies.objects.all(), widget=FilteredSelectMultiple("verbose name", is_stacked=False))
class Meta:
model = HuntingReport
exclude = ['user']
def __init__(self, user, *args, **kwargs):
super(HuntingReportForm, self).__init__(*args, **kwargs)
users = User.objects.filter(userprofile__outfitter=True)
self.fields['outfitter'].choices = [('', '')] + [(user.pk, user.get_full_name()) for user in users]
my views.py
def create(request, template_name='reports/new.html'):
if request.method == 'POST':
form = HuntingReportForm(request.POST, request.FILES)
if form.is_valid():
newform = form.save(commit=False)
newform.user = request.user
newform.save_m2m()
return HttpResponseRedirect('/hunting-reports/')
else:
form = HuntingReportForm(request.user)
context = { 'form':form, }
return render_to_response(template_name, context,
context_instance=RequestContext(request))
Did you try passing blank=True for model field's constructor, or required=False for the ModelMultipleChoiceField's constructor?
I know that blank=True solves the problem for the form in the admin panel, but I don't know how it gets mapped to the ModelForm's fields. I'm assuming that it gets mapped to required property.
