Django How to make use of the creation method for a custom user with permissions?
So I have this method: def create_editor(self, email, dob, password): user = self.create_user( email, dob, accepted_tos=True, password=password ) try: editors = Group.objects.get(name__iexact="Editors") except Group.DoesNotExist: editors = Group.objects.create(name="Editors") editors.permissions.add(Permission.objects.get(codename="can_give_discount")) # add can_give_discount permission user.groups.add(editors) user.save() return user To create a normal user and then add the user to the editor group I want to be able to create a manager from the normal django admin.

How to create a custom widget using django for use on external sites
I hava a new site that I am working on. The site will have prior agreement with eCommerce sites to include add-ons on their website. Consider the following example: My website, ABC.com is targeting ecommerce sites. For every ecommerce site that sells product X, I want them to include an add-on that gives buyers the option to purchase service Z if they so desire. ABC.com will be communicating with the ecommerce sites through a REST API. My challenge is how to integrate my service as an add-on into the external ecommerce sites. This I assume will be in the form of a widget, HTML code, or a bit of javascript. Something similar to the attached image from Amazon.com. I'm aiming to make a simple integration with the external sites to avoid having them do too much on their end. Is there a best practice on how to handle this? See an example from Amazon: -

Django why is a permissions code name different from checking if it has a permission?
When adding a permission to a group I use: managers.permissions.add( Permission.objects.get(codename='add_user') ) Using the codename add_user Now when checking if a user has a particular permission, I use users.add_user ie. the app_name prepended self.assertTrue(self.user.has_perm('users.add_user')) Why is that. Is it possible to get the permission with users.add_user. When I try it I get: django.contrib.auth.models.DoesNotExist: Permission matching query does not exist. -
What happen if `queryset` and `get_queryset` are both defined on a Django ViewSet that inherits from GenericViewSet
I've inherited some Django code and I am struggling to work out what the previous developers have intended with their code. There is a ViewSet which is configured, which inherits from GenericViewSet. In the class it defines a queryset variable but also defines a get_queryset method. I'm struggling to work out from the docs and tutorials what this even means? What's more interesting is that the get_queryset method returns a queryset of one type, but the queryset variable defines a different type. What I'm hoping for is for both querysets to be combined (which is the desired behaviour, and which appears to be happening on one server, but not another, so some additional investigation will be needed to work out why) Code below: class FeedbackFieldViewSet(NestedViewSetMixin, customer_mixins.CustomerProviderMixin, mixins.ListModelMixin, viewsets.GenericViewSet): ## # Instantiates and returns the list of permissions required by this viewset. # # @return The list of permissions. # def get_permissions(self): # Maps action names to tuples of permission classes. permissionDict = { "list": self.listPermissionClasses, } if self.action in permissionDict: return [permission() for permission in permissionDict[self.action]] if self.request.method == "OPTIONS": # Anyone can submit an options request return [] raise ProgrammingException("A request with an unknown permission model was received.") listPermissionClasses … -
Change queryset before passing to template Django
I have a many-to-many relationship between two models Foo and Bar. class Foo(models.Model): ... class Bar(models.Model): ... foo = models.ManyToManyField(Foo) I do the following database queries in order to get all of the entries for Foo that are null for a certain field. I am then able to get all the entries in Bar that match the many-to-many relationship. bar = Bar.objects.filter(field__isnull=True) foo_bar_pks = bar.values('foo') foo = Foo.objects.filter(pk__in=foo_bar_pks) I want to replace the value stored at Bar.foo to the corresponding value in foo. Because when I pass to the template I want to use a for loop to go through bar and be able to display the correct foo value. -
Modify required flag of field in Django Class Based View
I have following model used in my Django CBV CreateView: class Agreement(BaseModel): offer = models.ForeignKey(Offer, null=True, blank=True) owner_name = models.CharField(), max_length=15, null=True, blank=False) has_second_owner = models.BooleanField(default=False) second_owner_name = models.CharField(max_length=15, null=True, blank=True) And form: class AgreementForm(BootstrapFormMixin, forms.ModelForm): class Meta: model = Agreement fields = ('owner_name', 'has_second_owner', 'second_owner_name') def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper() self.helper.form_class = 'form-horizontal' self.helper.label_class = 'col-sm-5' self.helper.field_class = 'col-sm-7' self.helper.field_template = 'bootstrap3/layout/inline_field.html' self.helper.form_id = self.__class__.__name__.lower() self.helper.layout = Layout( Field('owner_name'), Field('has_second_owner'), Field('second_owner_name'), ) I am using CreateView to crate instances of Agreement model. By default, second_owner_name isn't required (because has_second_owner is False). In case user change has_second_owner field I have to modify second_owner_name field to be required in the view. How should I do this? What is a proper method to modify fields depending on POST data? Thank you -
Django InlineFormset : Customize inputs and widget
I’m using inlineformsets for an Image Model in combination with a Product Model. For the Image Model (using javascript): 1) a remove/delete button will be available to remove an image; the image can be remove not only on edit, but also on creation(the use upload the image, but before saving doesn’t like the image and removes it) 2) An add button, when the user clicks a new input and corresponding fields are added By default the inlineformset code is like this: <tr><th><label for="id_product_images-0-document">Document:</label></th><td><input type="file" name="product_documents-0-document" id="id_product_images-0-document" /></td></tr> <tr><th><label for="id_product_images-0-file_type">File type:</label></th><td><input type="text" name="product_documents-0-file_type" maxlength="255" id="id_product_images-0-file_type" /></td></tr> <tr><th><label for="id_product_images-0-DELETE">Delete:</label></th><td><input type="checkbox" name="product_documents-0-DELETE" id="id_product_images-0-DELETE" /><input type="hidden" name="product_documents-0-id" id="id_product_images-0-id" /><input type="hidden" name="product_documents-0-product" id="id_product_images-0-product" /></td></tr> Using inputs I can do it with javascript, but things get a little more complicated for what I want to do: The user should click on an image button a modal window will appear with the option to crop. Now the Upload button is in the modal window. The user is cropping, I select and save the coordinates with javascript, also show a cropped image (simulated using css). How do I transfer all this mechanism to Django inputs so formsets can understand what I want to do ? -

how to test inline formset
There is an inline formset that works perfectly well. It fails only in testing. there is a model that connects two types of participants: senders and receivers. models.py: class SendReceive(models.Model): receiver =jmodels.ForeignKey(Player, related_name='receiver') sender = models.ForeignKey(Player, related_name='sender') amount_requested = models.IntegerField() amount_sent = models.IntegerField(blank=True) An inline formset is shown to senders, who choose how much to send to receivers: forms.py: class SRForm(forms.ModelForm): class Meta: model = SendReceive fields = ['amount_sent'] SRFormSet = inlineformset_factory(Player, SendReceive, fk_name='sender', can_delete=False, extra=0, form=SRForm, ) and views.py (CBV): def post(self): context = super().get_context_data() formset = SRFormSet(self.request.POST, instance=self.player) context['formset'] = formset if not formset.is_valid(): return self.render_to_response(context) formset.save() return super().post() so, when I try to test it, the line formset.save() brings in error: django.db.utils.IntegrityError: NOT NULL constraint failed: riskpooling_sendreceive.receiver_id as the receiver id was not set. Although, if I look at the content of the formset.forms which is returned, everything is in there. Again, in the real life everything is ok, and is properly saved. So only testing results in error.

Trouble updating BooleanField with Django ModelForm
Using Django 1.11 and Python 3.4 I have a model: class ToDo(models.Model): completed = models.BooleanField(default=False) I want users to be able to update this field for the model by clicking a checkbox, so I made a ModelForm as follows: class CompletedForm(ModelForm): class Meta: model = ToDo fields = ['completed'] The problem I am having is understanding how I can get the database to update whenever the user clicks the checkbox, so that the completed field will toggle between True or False. In views.py: if request.method == 'POST': for x in range(0, all_todos.count()): a = all_todos[x] completedform = CompletedForm(request.POST, instance=a) else: for x in range(0, all_todos.count()): a = all_todos[x] print(a) completedform = CompletedForm(instance=a) I've rendered the checkboxes in the event of either GET or POST method, and linked each box to a particular instance. I assume that most of the logic will take place in the POST method since this is making a change to the database. Thank you -
