How do I properly handle prefix and delete items
I have a formset in django, Some forms have been deleted and some have not, plus I have a ForeignKey link into the model I am using models.py: class Client(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) group = models.CharField(max_length=50) class Meta: # make sure we can have unique phone number to each client unique_together = ('phone_number', 'group',) class ExtraPhoneData(models.Model): client = models.ForeignKey(Client, on_delete=models.DO_NOTHING) group = models.CharField(max_length=50) phone_number = PhoneNumberField(blank=False) class Meta: # make sure we can have unique phone number to each client unique_together = ('phone_number', 'group',) forms.py: class AddClientPhonetData(AjaxFormMixin, forms.ModelForm): template_name = 'client/phone_form.html' class Meta: model = ExtraPhoneData fields = ('phone_number',) widgets = { 'phone_number': forms.TextInput(attrs={'class':'form-control', 'placeholder': 'Extra Phone Number'}), } FormsetAddExtraPhoneData = inlineformset_factory(Client, ExtraPhoneData,form=AddClientPhonetData, extra=1, fields=('phone_number',), can_delete=True) views: def CreateClient(request, template='client/new_client.html'): if request.method == 'POST': updated_request = UpdateGroupAndCreator(request, uuid) forms = {} forms["extra_phone"]= FormsetAddExtraPhoneData(updated_request,prefix="extraPhone") forms["client_form"] = AddClientForm(updated_request, prefix="basicData") if forms["extra_phone"].is_valid() and forms["client_form"].is_valid(): # save client obj client = forms["client_form"].save() # save formsets formset_almost_commit = forms["extra_phone"].save(commit=False) # delete objects of flaged as deleted for obj in forms["extra_phone"].deleted_objects: obj.delete() # add ForeignKey to the rest and save them for commits in formset_almost_commit: commits.client = client_obj commits.save() # -> yield error relation "client_extraphonedata" does not exist LINE 1: INSERT INTO "client_extraphonedata" … -
Is there a way to automatically include text fields in a Django form?
I am creating a form in Django. There are some static fields included but I also want to include some fields based on a csv file.

Implement inline grid editing as global function

How to redirect with middleware in Django
I wrote this program so that the user would be moved to my target page if it had certain conditions. This is my custom Django middleware: def check_userprofile_middleware(get_response): def middleware(request): response = get_response(request) if request.user.is_authenticated: # Profile conditions goes here. if profile_condition: return redirect(reverse('base:edit_user_profile')) return response return middleware if I use return in if statement: Redirect to 'base:edit_user_profile' url, But after that I see this error on browser: This page isn’t working 127.0.0.1 redirected you too many times. Try clearing your cookies. ERR_TOO_MANY_REDIRECTS If I don't use "return in "if" statement: Everything goes correct,except redirection! What is worng with this? -
Singleton object behaviour in Django
Consider I want to create a singleton object for each user accessing a particular feature in the website. This object is not a Model. class NavApi: __instance = None @staticmethod def get_instance(): """ Static access method. """ if NavApi.__instance is None: Client() return NavApi.__instance In views file @csrf_exempt def get_folder_tree(request): if request.method == "POST": nav_api = NavAPI.get_instance() folders = nav_api.listing_folders(request.POST.get('id')) return render(request, "folder_tree.html", {'folders': folders, 'page1': False}) @csrf_exempt def get_prev_folder_tree(request): if request.method == "POST": nav_api = NavAPI.get_instance() page1,folders = nav_api.listing_prev_folder_tree() return render(request, "folder_tree.html", {'folders': folders,'page1':page1}) The reason for using Singleton is that the class object has few members which defines the state of the folder/contents/current folder_id etc. And it should not be created for every view. It needed to be reused But when I tried to run it as public, using ngrok and shared the linked to my friend, and testing the navigation features, We ended up using the same singleton object. When I was browsing contents of Folder A, and he was browsing contents of Folder B, we ended up recieving contents of the same folder(either A or B). How to overcome this? -

How to manage django model relations properly?
Here I am making some tour package system.A package will have gallery.And of course gallery will have multiple images so I decided to use ManyToOne relation here.But I also thought of using OneToOne relation between these two models because we can upload multiple images at once through django forms. So what relation would be best here ? class TourPackage(models.Model): name = models.CharField(max_length=255) package_start_date = models.DateTimeField() price = models.FloatField(default=0.0) facilities = models.TextField() class PackageGallery(models.Model): package = models.ForeignKey(TourPackage,on_delete=models.CASCADE) images = models.ImageField(upload_to='gallery') -
Create default related objects when instantiating model
Given two abstract models A and B: class A(models.Model): title = models.Field(...) ... And: class B(models.Model): a = models.ForeignKey(A, ...) ... How to create a set of related objects of model B every time new record of model A is created? At the moment the most straight-forward approach seems to be using: @receiver(models.signals.post_save, sender=A) def create_default_b_objects(sender, instance, created, **kwargs): if created: #create related instances of model B ... But maybe there's more elegant way by using data migrations or fixtures described in django documentation? -
Deserialization to specific object based on field value in djnago
Right now I have an object model: class Report(models.Model): TYPE1 = 'type1' TYPE2 = 'type2' TYPES_CHOICES = [ (TYPE1, 'type1'), (TYPE2, 'type2'), ] name = models.CharField(max_length=255) type = models.CharField(max_length=20, choices=TYPES_CHOICES) and ModelSerializer which corresponds to this model: class ReportSerializer(serializers.ModelSerializer): class Meta: model = Report depth = 1 fields = ('name', 'type') Basing on type value I would like to create Type1Report or Type2Report (they will implement some methods in another way). But both Type1Report and Type2Report should be saved in the same database table. Is there a way to do it with the use of the DRF serializer and without walkarounds? If there is no such a way what is the best practice to do so? -

How can I ignore unknown arguments passed as inputs to a mutation?

I'm also using syslog, so the settings.LOGGING dictionary is something like this: LOGGING = { "version": 1, "disable_existing_loggers": False, "handlers": { "console": { "level": "DEBUG", "class": "logging.StreamHandler", "formatter": "default", }, "syslog": { "level": "DEBUG", "class": "logging.handlers.SysLogHandler", "formatter": "default", "facility": SysLogHandler.LOG_LOCAL2, "address": syslog_address, }, }, "loggers": { "django": {"handlers": ["console", "syslog"], "propagate": True}, "apps": {"handlers": ["console", "syslog"], "level": "DEBUG"}, "utils": {"handlers": ["console", "syslog"], "level": "DEBUG"}, "gunicorn.access": {"handlers": ["console", "syslog"], "level": "INFO"}, "gunicorn.error": {"handlers": ["console", "syslog"], "level": "INFO"}, }, } Note that I explicitly added the gunicorn.access logger for use with syslog (see: https://github.com/benoitc/gunicorn/issues/2016). -

Update after a delete with Vue.JS, Django REST
I am testing the functioning of VueJS and Django REST. For the moment I can display the data stored in REST and modify them. I can also delete them but I have to reload the page to see the deletion. I would like the line in the table that is deleted to be done without reloading the page. Can you help me? <script> export default { data () { return { users: [], } }, mounted () { this.$user = this.$resource('"APIaddress"/prescripteur{/id}/') this.$user.query().then((response) => { this.users = response.data },(response) => { console.log('erreur', response) }) }, methods: { create (user) { }, save (user) { this.$user.update({id: user.id}, { nom: user.nom, prenom: user.prenom, adresse1: user.adresse1, cp: user.cp, ville: user.ville, specialite: user.specialite, civilite: user.civilite }).then((response) => { }, (response) => { console.log('erreur', response) }) }, destroy (user) { this.$user.remove({id: user.id}).then((response) => { }, (response) => { console.log('erreur', response) }) } } } </script> I tried to add that: updated () { this.$user = this.$resource('"APIaddress"/prescripteur{/id}/') this.$user.query().then((response) => { this.users = response.data },(response) => { console.log('erreur', response) }) }, But the recharging is done continuously and I can no longer modify the fields but the deletion is done.
