Local Settings in Django 2
I'm using Django 2 with Python 3.7 I want to import some settings from a file local_settings.py so I can include that file in a .gitignore so I don't share my secret keys on github. I have the folder tree set up like this: settings.py has this at the end: try: from local_settings import * except ImportError: pass ORDERS = '@catsinuniform.myshopify.com/admin/orders.json' PRODUCTS = '@catsinuniform.myshopify.com/admin/products.json' SHOPIFY_SECRET_KEY = '' SHOPIFY_PWORD = '' ORDERS_URL = f"https://{SHOPIFY_SECRET_KEY}:{SHOPIFY_PWORD}{ORDERS}" PRODUCTS_URL = f"https://{SHOPIFY_SECRET_KEY}:{SHOPIFY_PWORD}{PRODUCTS}" I would also like to put my SECRET_KEY in local_settings.py This isn't working and I can't find why not? Is it my Python version or Django? -

Django-filter: Choicefilter with checkbox widget doesn't work
So I'm using Django-filter and trying to render choicefilter as checkboxes in Html (so user can press a checkbox to select his choice rather then selecting from a list. I managed to render it correctly in the html which also seem to send the url correctly, however the the filtering action won't take effect by Django-Filter. Filter.py: import django_filters from festival_list.models import Festival from django.db import models from django import forms class FestivalFilter(django_filters.FilterSet): audience_style = django_filters.ChoiceFilter(choices=Festival.audience_style_choices,widget=forms.CheckboxSelectMultiple,) name = django_filters.CharFilter(lookup_expr='iexact') class Meta: model = Festival fields = ('name','audience_style') Template: <form action="" method="get"> <div class="row filters-row text-center"> {% for audienceStyle in filter.form.audience_style %} <div class="col col-pad"> {{ audienceStyle.tag }} <label for="{{ audienceStyle.id_for_label }}"><span class=""></span>{{ audienceStyle.choice_label }}</label> </div> {% endfor %} </div> <input type="submit" value="Submit" /> </form> When tried to add the auto form by Django-filter using it return an auto error that might give a clue: Select a valid choice. ['Rockers'] is not one of the available choices. (Rockers is one of the model field choices) Thanks =] -
overwrite form for django CreateView
Perhaps just another stupid beginner question: I am having trouble overwriting a django model form which is currently using the following code in views.py. The code below works well ! class PostCreateView(LoginRequiredMixin, CreateView): model = Post fields = ['title', 'content'] ### want this instead of line 1 and 2 above --> form_class = PostCreateForm() view_args = collections.namedtuple('view_args', ['page_title']) view_args = view_args(page_title="Create Post") def get_context_data(self, *args, **kwargs): self.tgt_url_args = MyHelper.parse_tgt_url(self) context = super(PostCreateView, self).get_context_data(*args, **kwargs) context.update(MyHelper.get_context_metadata(self, self.tgt_url_args, PostCreateView.view_args)) return context def form_valid(self, form): form.instance.author = self.request.user tgt_url_args = MyHelper.parse_tgt_url(self) blog_article = Article.objects.get(pk=tgt_url_args.get('Article', '0')) form.instance.article_field = blog_article return super().form_valid(form) However, I would like to overwrite the form in order to add placeholder to the fields. So I replace line 1 and 2 by: form_class = PostCreateForm() I also added the follwing in forms.py: from django import forms from . models import Post class PostCreateForm(forms.ModelForm): class Meta: model = Post fields = ['title', 'content'] print('imported PostCreateForm') When I import and run this however, I get the following error: 'PostCreateForm' object is not callable What am I doing wrong here? -
Django: How to randomize choices field of every existing model
I have 100 instances of a Model, but now I've added a new choices Field with a default value. It is working and every instance share the same field, but I want it to be randomize between the X values of the choices. This is a modified version of my model class MyModel(models.Model): A = 'a' B = 'b' C = 'c' CATEGORIES_CHOICES = ( (A, 'Ant'), (B, 'Buffalo'), (C, 'Cat'), ) category = models.CharField(max_length=1, choices=CATEGORIES_CHOICES, default=A) With that I can go to the shell and type the following: mymodel = MyModel.objects.get(id=1) mymodel.category = random.choices(MyModel.CATEGORIES_CHOICES)[0][0] mymodel.save() And it works, but can I automatize it to do it in all 100 instances? -
Does whitenoise really require collectstatic?
I'm exploring using whitenoise to serve static files in a Django application that's packaged in a Docker container. In the documentation it says: As part of deploying your application you’ll need to run ./manage.py collectstatic to put all your static files into STATIC_ROOT. (If you’re running on Heroku then this is done automatically for you.) Is that really needed? I'm not running ./manage.py collectstatic and static files are still served. If it's not needed, is it an optimization? I'm trying to avoid having needless steps in my deployment process. -

Callback url for webhooks with DRF
I am to receive notifications from a remote API in my application through a callback url I provided. If my callback url is https://example.com/api/callback and the remote API sends notifications using a GET to my app this way https://example.com/api/callback?invoice_id=BNSLE3 The problem is all their requests receive a 404, I was expecting that I can receive the data in their response with request.query_params but I obviously can't because the remote API can't reach this endpoint. This is the endpoint I used for the callback @csrf_exempt @list_route(methods=['GET'], permission_classes=[AllowAny]) def callback(self, request): print(request.query_params) print(request.data) return Response(status=status.HTTP_200_OK) How do I make my endpoint reachable to the external API because all I get is a 404 error. Extra info: I am using django viewsets when I make a request to https://example.com/api/callback without any params, I am able to hit that endpoint. -

Testing a Django model with custom save method calling external API

Temporary users in Django
I would like to implement temporary users in my project. The reason is that people should be able to auth in my application via Facebook Oauth or Facebook Account Kit. I've got 2 decisions, but each one is not ideal. 1) Create User and TemporaryUser models. The first one will have all info about regular user + unique db fields. This TemporaryUser will have only phone_number or facebook_id. Temporary user will be created on auth/ endpoint and response will have auth_token to be able perform registration later with all needed fields. The issue is: how will I determine that user is temporary and his auth_token is legit only for registration/ endpoint? 2) Create basic User model with 2 types: regular or temporary. This model will have only general fields. Also there will be different models with OneToOne relation with User. Only Users with type regular will be able to have that instances with OneToOne relation. The issue is: User model should have USERNAME_FIELD , REQUIRED_FIELDS to be able to login by admin panel + users with different types should have different managers. -

Making a Post method that accepts multiple items in a payload
I have a post method that uses the following payload shown below: { "avg_bid_per_unit":20, "sku": "SKU-009", "status": "OPEN", "supplier": null, "bid": [1,2,3,4] } Normally if bid item was not a list in the payload I would simply implement this: bid = Bid.objects.get(id=request.data['bid']) then I add the ID I got to the payload,in our case multiple IDs are being added to the list. I know there is some iteration involved since since we would like to add items in the bid list which is the best approach to add a list of items when posting. Here is my current Viewset implementation: class BidItemViewSet(viewsets.ViewSet,BaseRetrieveUpdateDestroyView): def create(self, request): """Create a bid item instance.""" bid= request.data.pop('bid') status = request.data['status'] avg_bid_per_unit=request.data['avg_bid_per_unit'] supplier =Supplier.objects.get(id=request.data['supplier']) sku = request.data['sku'] for item in bid: Bid.objects.get(id=request.data['bid']) # Calculate average_bid_per_unit, no_of_bids, in get method bid_obj = BidItem.objects.create( name = status, bid=bid, supplier=supplier, sku=sku, avg_bid_per_unit=avg_bid_per_unit, item= item, org_id =get_auth(request) ) serializer = BidDetailSerializer(bid_obj) return Response(data=serializer.data, status=status.HTTP_201_CREATED) Models class Bid(models.Model): STATUS_CHOICES = ( ('OPEN', 'OPEN'), ('CLOSED', 'CLOSED') ) bid_status = models.CharField(choices=STATUS_CHOICES, max_length=10) avg_bid_per_unit = models.IntegerField() item = models.ForeignKey(Item) org_id = models.IntegerField() # Add issue bid view def __str__(self): return str(self.item.name)+" "+str(self.bid_status) class BidItem(models.Model): # Bid Items View bid = models.ManyToManyField(Bid,related_name="bid_items") # multiple bitd … -
