Django. General design philosophy question: best way to implement "toggleable" separate features in a website
Let's say I want to create a blueprint of an online store that I can sell to potential clients. However, the idea is to make it so that the client chooses features that they want their store to have (from a pre-designated list) and pay only for those features, that way avoiding paying for something they don't need. So for example, one client wants to have and online store with a Cart, Purchase History, Graphs, Reports. Another one only wants simple registration and cart (but maybe in future they will want me to "enable" other features as well). My question is: what, in your opinion, is the best way to tackle this problem from a Django developer perspective? My thoughts: Create every feature as a separate app and deploy the whole thing commenting out the features that client did not pay for. And when a client wants additional features, I simply go to settings.py and uncomment the app they requested. Can I even make changes on the settings.py file on a live website without restarting it? Create an admin panel for myself (the superuser) that will have an ability to turn features on or off. So when the client pays … -
How to handle create/update on multiple nested serializers?
I've been able to make creating/updating happen on nested serializers, but I can't seem to get it to work when there are multiple many to many nest serializers. Models: class Brand(models.Model): name = models.CharField(max_length=500) class Incentive(models.Model): name = models.CharField(max_length=500) brands = models.ManyToManyField(Brand, related_name='incentives_brand') start_dt = models.DateTimeField(auto_now_add=False, blank=True, null=True) end_dt = models.DateTimeField(auto_now_add=False, blank=True, null=True) class Version(models.Model): name = models.CharField(max_length=1000) incentives = models.ManyToManyField(Incentive, related_name='versions_incentive', blank=True) brands = models.ManyToManyField(Brand, related_name='versions_brand') Serializers: class BrandSerializer(serializers.ModelSerializer): class Meta: model = Brand depth = 1 fields = ['id', 'name'] class IncentiveSerializer(serializers.ModelSerializer): brands = BrandSerializer(many=True) class Meta: model = Incentive # depth = 1 fields = ['id', 'name', 'brands', 'start_dt', 'end_dt'] class VersionSerializer(serializers.ModelSerializer): incentives = IncentiveSerializer(many=True) brands = BrandSerializer(many=True) class Meta: model = Version fields = ['id', 'name', 'incentives', 'brands'] def create(self, validated_data): brands = validated_data.pop('brands', []) incentives = validated_data.pop('incentives', []) instance = Version.objects.create(**validated_data) for brand_data in brands: brand = Brand.objects.get(**brand_data) instance.brands.add(brand) for incentive_data in incentives: incentive = Incentive.objects.get(**incentive_data) instance.incentives.add(incentive) return instance def update(self, instance, validated_data): brands = validated_data.pop('brands', []) incentives = validated_data.pop('incentives', []) instance = super().update(instance, validated_data) brand_objs = [] incentive_objs = [] for brand_data in brands: brand = Brand.objects.get(**brand_data) brand_objs.append(brand) instance.brands.set(brand_objs) for incentive_data in incentives: incentive = Incentive.objects.get(**incentive_data) incentive_objs.append(incentive) instance.incentives.set(incentive_objs) return instance I tried using the … -
How to filter queryset based on boolean value, then count in template
I want to count how many jobs are open vs closed. I don't understand why this isn't working, I have added {{ap.id}} and {{open.line_num_id }} after the forloop just to see what was rendered. I would think that if they match, then it's added to the count. This is not the case, all jobs are counted regardless of the "if" statement. Totally lost as to what is happening and why. Any help would be very appreciated . I have two models: class Airplane(models.Model): line_num = models.CharField(max_length=10, unique=True) vh_num = models.CharField(max_length=4, unique=True) vz_num = models.CharField(max_length=4, unique=True) stall = models.CharField(max_length=30, choices=stall_picker) status = models.CharField(max_length=30, choices=status_picker) owner = models.ForeignKey(User, on_delete=models.CASCADE) is_completed = models.BooleanField(default=False) pm = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.line_num class Job(models.Model): line_num = models.ForeignKey( Airplane, on_delete=models.CASCADE, related_name="ap_jobs") job_num = models.CharField(max_length=10, unique=True) description = models.CharField(max_length=200) status = models.CharField(max_length=30, choices=status_picker) category = models.CharField(max_length=30, choices=categories_picker) is_completed = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class meta: ordering = ["category", "status"] def __str__(self): return (f"{self.job_num}: {self.description} : {self.is_completed}") My View: def Ap_linup(request): context = { 'ap_list': Airplane.objects.all().filter(is_completed=False), 'open_jobs': Job.objects.all().filter(is_completed=False), 'closed_jobs': Job.objects.all().filter(is_completed=True) } return render(request, 'airplane/airplane_list.html', context) Template: {% extends 'base.html' %} {% block title %} Airplane List {% endblock %} … -
Where does this (Django) CustomUser field come from?
My searches only turned up tips on how to add fields or add_fieldsets in admin.py when using Django's CustomUser. I need to find out where a field named admin comes from when the model form is rendered in the class-based CreateView. There is no error with the code, but the template automatically adds an admin choice field on top of the page-the drop-down choices are users (all 3 types) already created. But I want to create a new staff user. So how do I tell Django to leave the admin field out (at least until a user is saved)? # models.py class CustomUser(AbstractUser): user_type_data = ((1, "HOD"), (2, "Staff"), (3, "Student")) user_type = models.CharField(default=1, choices=user_type_data, max_length=10) class Staff(models.Model): id = models.AutoField(primary_key=True) admin = models.OneToOneField(CustomUser, on_delete=models.CASCADE) email = models.EmailField() objects = models.Manager() # forms.py class StaffForm(forms.ModelForm): model = Staff first_name = forms.CharField(required=True) last_name = forms.CharField(required=True) class Meta: model = Staff fields = '__all__' # views.py class StaffCreateView(CreateView): model = Staff form_class = StaffForm context_object_name = 'staff' success_url = reverse_lazy('staff_list') # staff_form.html <form method="post"> {{ form.as_p }} <input type="submit" value="Save"> </form> -

show aggragated data in admin changelist_view
I have an app where I am tracking user searches. The table currently looks like this: What I want to change is the view. I'd dlike to group/aggregate/annotate the view based on Search Term column and keep the latest date of each search term. The column User searches is being updated when user puts the same term in the search bar so there is no need for me to keep all records. I just need the latest one. I tried to update queryset using distinct() and annotate() in admin model but with no success. In other words I want to have 1 unique term in the table with the latest date (Searched on column). Below is my code: models.py class SearchQueryTracker(models.Model): id = models.AutoField(primary_key=True) author = models.ForeignKey(User, blank=True, null=True, on_delete=models.SET_NULL, unique=False) total_results = models.IntegerField('Search results', default=0) total_searches = models.IntegerField('User searches', default=0) search_term = models.CharField(max_length=1000, blank=True, null=True) searched_on = models.DateTimeField('searched on', default=timezone.now) views.py @login_required def SearchViewFBV(request): query = request.GET.get('q') query_list = request.GET.get('q', None).split() query_list_count = len(query_list) user = User.objects.get(email=request.user.email) find_duplicate_results = SearchQueryTracker.objects.filter(search_term=query).update(total_searches=F('total_searches') + 1) .... search_tracker = SearchQueryTracker() search_tracker.total_searches = find_duplicate_results search_tracker.author = user search_tracker.search_term = query search_tracker.save() admin.py class SearchQueryTrackerAdmin(ImportExportModelAdmin): list_display = ('search_term', 'author', 'total_results', 'total_searches', 'searched_on') readonly_fields = list_display … -

Django Redirect by Name - No Reverse Match Error
My django project name is 'exercises' and the app name is 'practice'. This basic application allows a user can navigate to different pages with a button click. The reference to each page uses the following href: {% url 'practice:redirector' project.pk %} Where practice:redirector points to my app (practice) url path named redirector. It is parameterized with the primary key of the page which I am trying to redirect to. See below from django.urls import path from practice import views app_name = "practice" urlpatterns = [ path('', views.all_sites, name="all_sites"), path('<int:pk>', views.redirector, name='redirector'), path('clickToAddItems', views.clickToAddItems, name='clickToAddItems'), path('displayEvens', views.displayEvens, name='displayEvens'), path('displayMousePosition', views.displayMousePosition, name='displayMousePosition'), path('luckySevens', views.luckySevens, name='luckySevens'), ] This url points to the views within practice. There, I have a view set up for each page that corresponds to the name that the page will display. I also have a re director view that uses the pk passed in the url to pull the relevant page from my database and use the name as the argument in the redirect() shortcut: from django.shortcuts import render, redirect from practice.models import Project app_name = "practice" # Create your views here. # Main list of javascript sites def all_sites(request): # query my project model to return all site … -
How to properly update a many to many nested serializer?
I have been able to replicate the create method to add the correct nested serializers in a POST request. However, I'm still having issues updating in a PUT or PATCH. When using a PUT or PATCH request and I pass the entire object data or the "brands" data, it will only update in the position it is passed. So if I have an object with 3 values: "brands": [ { "id": 1, "name": "Brand 1 Test" }, { "id": 2, "name": "Brand 2 Test" }, { "id": 3, "name": "Brand 3 Test" } } If I pass: "brands": [ { "id": 1, "name": "Brand 1 Test" }, { "id": 2, "name": "Brand 2 Test" } It will give me the same list of 3 brands. But if I do that in reverse order it will update and add the 3rd brand. I'm not sure what's causing it. Here's the code I have: Models class Brand(models.Model): name = models.CharField(max_length=500) class Incentive(models.Model): name = models.CharField(max_length=500) brands = models.ManyToManyField(Brand, related_name='incentives_brand') start_dt = models.DateTimeField(auto_now_add=False, blank=True, null=True) end_dt = models.DateTimeField(auto_now_add=False, blank=True, null=True) Serializers class BrandSerializer(serializers.ModelSerializer): class Meta: model = Brand depth = 1 fields = ['id', 'name'] class IncentiveSerializer(serializers.ModelSerializer): brands = BrandSerializer(many=True) class Meta: model … -

Custom field - got multiple values for keyword argument 'related_name'
I'm working on a custom field that is just a shortcut to ForeignKey that points to addresses.Country model. When I run makemigrations it returns this error with I'm not sure: TypeError: Couldn't reconstruct field rsft_country on properties.Property: django.db.models.fields.related.ForeignKey.__init__() got multiple values for keyword argument 'to' I understand that there are two to arguments passed but I don't understand why.

How do I leverage react components from python email templates?
We have a django/react app that has a lot of work put into creating some react components that we want to reuse in some templated emails. Most of the components are in their own package outside of the actual react app. How should we incorporate these components into emails without having to rewrite them all? I'm assuming this will involve making a smaller react app hat only renders the content for the email then use that from some service to generate the python email template? I feel like this could be a large opened ended question but please add comments about how I could make it more specific and I will be happy to make changes. Also I feel like this has to be a common problem and wouldn't mind being pointed in the direction of some preexisting questions or articles as my googling must be lacking today. -
