This is for an assignment, we need to store the images in the static directory and display them on a template. The images are stored through the item model ImageField and uploaded to the static/images directory. Here is the template code: {% load static %} <p><a href='..'>Home</a></p> {% block content %} <table> <tr> <th>Item Name</th> <th>Manufacturer</th> <th>Cost</th> <th>Weight</th> <th>Image</th> </tr> {% for i in name %} {% if i.name == params %} <tr> <td>{{i.name}}</td> <td>{{i.manufacturer}}</td> <td>{{i.cost}}</td> <td>{{i.weight}}</td> <td><img src="{% static i.image.url %}" alt="{{i.image.url}}"></img></td> </tr> {% endif %} {% endfor %} </table> {% endblock %} I have the following model code: from django.db import models class item(models.Model): name = models.CharField(max_length=40) manufacturer = models.CharField(max_length=255) cost = models.DecimalField(max_digits=10, decimal_places=2) weight = models.DecimalField(max_digits=10, decimal_places=2) image = models.ImageField(upload_to='static/images/') Here are the current settings import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

How do I make a custom form errors section in my Django template?
In my Django template I can show errors using this syntax {{ form.errors }}. But that evaluates to this html syntax in my template: <ul class="errorlist"> <li>password <ul class="errorlist"> <li>Ensure this value has at least 10 characters (it has 2).</li> </ul> </li> <li>confirm_password <ul class="errorlist"> <li>Ensure this value has at least 10 characters (it has 2).</li> </ul> </li> <li>first_name <ul class="errorlist"> <li>Ensure this value has at least 2 characters (it has 1).</li> </ul> </li> <li>last_name <ul class="errorlist"> <li>Ensure this value has at least 2 characters (it has 1).</li> </ul> </li> </ul> This is not the html syntax I want. I actually want to wrap them in my own elements. For example {%if form.errors %} <section class="errors-container"> {% for err in form.errors %} <p>{{err.field_name}}</p> <div> {{err.actual_error_for_field_name}} </div> {% endfor %} </section> {%endif%} That is the layout I want. I even tried passing an errors variable to the context dictionary in my view. def user_register(request): errors = {} if request.method == 'POST': form = PersonRegisterForm(request.POST) if form.is_valid(): if form.cleaned_data['password'] == form.cleaned_data['confirm_password']: cd = form.cleaned_data new_user = Person.objects.create_user(username=cd['username'], email=cd['email'], password=cd['password'], first_name=cd['first_name'], last_name=cd['last_name']) messages.success(request, f'You are successfully registered as {new_user.username}!') return redirect("profile", new_user.id) for i in form.errors: errors[i] = form.errors[i] print(errors) else: form = … -
Django change value before save in ModelViewSet
I am new to Django (and the REST framework) but I am struggling to update a value before save. Right now I am using a simple ModelViewSet to update a record. Everything works, but the value doesnt get updated if I create an item in de admin site. Code of the view is as follows: class OauthProviderViewSet(viewsets.ModelViewSet): queryset = OauthProvider.objects.all() serializer_class = OauthProviderSerializer authentication_classes = [SessionAuthentication, BasicAuthentication] permission_classes = [IsAdminUser] def perform_create(self, serializer): changed_credentials = "test" + self.request.credentials serializer.save(credentials=changed_credentials) I just want to pre-pend the word test to the credentials field. -
Django REST Framework: Creating Object and Connecting Foreign Key with Serializers
Currently, my TaskList objects are connected to my TaskItem objects by a foreign key (with the TaskItems being in a list called task_items). I am able to add items in the shell to the list fine, but when it comes to the serializer I haven't been able to figure out how to connect these two entities. The request.data object and the serializer.data object are not compatible to work with the DB API commands. Is this possible to do? If so, what would be the best way to go about this? models.py class TaskItem(models.Model): task_name = models.CharField(max_length=200) difficulty_level = models.IntegerField(default=1) def __str__(self): return self.task_name class TaskList(models.Model): list_name = models.CharField(max_length=200) user = models.ForeignKey(User, on_delete=models.CASCADE) task_items = models.ManyToManyField(TaskItem) def __str__(self): return self.list_name serializers.py class TaskSerializer(serializers.ModelSerializer): class Meta: model = TaskItem fields = '__all__' class TaskListSerializer(serializers.ModelSerializer): TaskItem = TaskSerializer() class Meta: model = TaskList fields = '__all__' # list_name, user, task_items views.py @api_view(['POST']) def addTask(request, pk): user = User.objects.get(id=pk) taskList = TaskList.objects.select_related().filter(user=user).first() taskListSerializer = TaskListSerializer(taskList) serializer = TaskSerializer(data=request.data) if serializer.is_valid() and taskListSerializer.is_valid(): serializer.save() return Response(serializer.data) -
How to make nested jsonb model with django / postgres?

This is the model so far class Menu(models.Model): burgers = ArrayField( ArrayField( models.CharField(max_length=10, blank=True), size=8, ), size=8, default=None ) beverages = ArrayField( ArrayField( models.CharField(max_length=10, blank=True), size=8, ), size=8, default=None ) extras = ArrayField( ArrayField( models.CharField(max_length=10, blank=True), size=8, ), size=8, default=None ) fries = ArrayField( ArrayField( models.CharField(max_length=10, blank=True), size=8, ), size=8, default=None ) I want to make each item inside the Array to have its own fields for the name and price. { "burgers": [ 0:{ "name":"Plain patty", "price":4 }, 1:{ "name":"Cheese buns", "price":8 } ] } How can I make it with jsonb? -
How can i check if the function based view was called from another redirect function or directly from the url?
I have an online store where users pay at domain.com/pay and receive their product after paying at domain.com/done However, when I was testing it I found out that users can go to the URL and type domain.com/pay manually and all a sudden, they get their product without paying! I want someway to check whether the user accessed it manually or from a redirection, if manually then raise http403 if from redirect then the function will happen normally Here is my process_pay view def payment_process(request, trade_id): trade = get_object_or_404(Trade, id=trade_id) host = request.get_host() paypal_dict = { 'business': trade.seller.email, 'amount': Decimal(trade.price), 'item_name': trade.filename, 'invoice': str(trade.id), 'currency_code': 'USD', 'notify_url': 'http://{}{}'.format(host, reverse('paypal-ipn')), 'return_url': 'http://{}{}/{}'.format(host, *reverse('payment_done', kwargs={'trade_id': trade.id})), 'cancel_return': 'http://{}{}'.format(host, reverse('home')), } form = PayPalPaymentsForm(initial=paypal_dict) return render(request, 'payment/payment_process.html', {'trade': trade, 'form': form}) my done_process view @csrf_exempt def payment_done(request, trade_id): # if user entered from a redirection: # Give product to user # elif user entered manually: raise http403 # else: messages.error(request, 'something went wrong') return redirect('home') return redirect('trade:inbox') -
Filter api view from another view result Django (REST)
I have 2 API returned in Django like this. List of apps: {"count":3,"next":null,"previous":null,"results":[ {"id":1,"user":"x","name":"app1","title":"title1","active_user":"user1"}, {"id":2,"user":"x","name":"app2","title":"title2","active_user":"user1"}, {"id":3,"user":"x","name":"app3","title":"title3","active_user":"user1"}]} This API have X ids or name (only 3 here for the example), imagine 100 or more. They must match with the second API (field id or name of list_apps). And the second has already been filtered for just the active user. User data: {"count":1,"next":null,"previous":null,"results":[ {"user":"user","email":"none","list_apps":{ "1":{"id":"1","hgt":"1","pos":"1","wth":"1","name":"hello","color":"default","visible":"true"}, "2":{"id":"2","hgt":"1","pos":"2","wth":"1","name":"dash","color":"default","visible":"true"}, So, in this case, I expected to return only the 2 first app in the first API (list of app), because the user have only access to 1 and 2. (list_apps are from a PostGre JSON field). Answer expected: {"count":3,"next":null,"previous":null,"results":[ {"id":1,"user":"x","name":"app1","title":"title1","active_user":"user1"}, {"id":2,"user":"x","name":"app2","title":"title2","active_user":"user1"}]}, Here's the view.py @permission_classes([IsAuthenticated]) class DashListCreate(generics.ListCreateAPIView): renderer_classes = [JSONRenderer] serializer_class = DashSerializer def get_queryset(self): return Dash.objects.filter(id__in=["1","2","3"]) @permission_classes([IsAuthenticated]) class UserDashListCreate(generics.ListCreateAPIView): renderer_classes = [JSONRenderer] serializer_class = UsersDashSerializer def get_queryset(self): print(UsersDash.objects.only('list_apps').values()) return UsersDash.objects.filter(user=self.request.user) The answer is maybe replace the field ["1","2","3"] in the filter by the list of "id" in the other api : list_app.api.all() but i don't know 2 things : How to call an API from Another Just select the values I need, I tried only('list_apps').values() but it does not work (no filter). Is it a good practice to filter in the view or there … -
Django - Is this solution DRY or is there a better way to model these profile classes and subclasses?
Basically, I have the following requirements: A user has a personal user profile An organisation can have a staff profile The staff profile can be independent or link to a user The organisation can edit the staff profile without changing the users' personal user profile A user changing their personal user profile wouldn't affect an organisations staff profile of the user A user can be staff at multiple organisations (and hence have multiple staff profiles) A user doesn't have to be staff Currently I have the following classes (Irrelevant fields removed for simplicity) profiles.models.py class Profile(TimeStampMixin): title = models.CharField(max_length=6, choices=Title.choices, blank=True) forename = models.CharField(max_length=50, blank=True) surname = models.CharField(max_length=50, blank=True) class UserProfile(Profile): user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name="profile", on_delete=models.CASCADE) class StaffProfile(Profile): user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, db_index=True, related_name="staff_profiles") organisations.models.py class Organisation(TimeStampMixin): staff = models.ManyToManyField('profiles.StaffProfile', blank=True, related_name="organisations") What I'm wondering is whether this solution is DRY and whether it's the best way of dealing with the requirements? The reason I'm not sure is because I've contemplated having StaffProfile extend UserProfile instead of Profile and changing the OneToOneField in UserProfile to a ForeignKey Field however this seems like it would complicate finding a User's personal profile from their staff profile. Unless I change the related_name … -
Postgres procedure not updating selected row
I'm working on a Django application that uses Stored Procedures on a PostgreSQL database. I'm stuck in a very strange (for me, at least) problem. I have the following SP code: create procedure inbound_550(p_operation_id integer) language plpgsql as $$ declare file_operation record; ... begin select oo.id, oo.file_id, ot.transaction_type_id, ot.code into file_operation from operations_operation oo join operations_type ot on ot.id = oo.type_id where oo.id = p_operation_id; for line in # select some records from other tables using parameter p_operation_id on some FKs loop # business logic here with some calculations and some inserts sum_tax_day = X # some value end loop; operation_avg_year_tax = ((1 + (sum_tax_day / 100)) ^ 252) - 1; update operations_operation set avg_year_tax = operation_avg_year_tax where id = p_operation_id; end $$; The problem is, when I call this procedure from the console it runs fine and the field avg_year_tax gets updated with the operation_avg_year_tax value but, when I call the procedure from my application using Python and psycopg2 the field is not updated, it seems that the update statement is ignored. Here is the Python code used to call the procedure: from django.db import connection class Inbound: def __init__(self, operation): self.operation = operation def main(self): conn = connection … -

I can not access to mount directory from Django when using docker
I run Django in docker and I want to read a file from host. I mount a path in host to container using following command in my docker-compose file: volumes: - /path/on/host/sharedV:/var/www/project/src/sharedV Then I execute mongodump and export a collection into sharedV on host. After that, I inspect web container and go to the sharedV directory in container and I can see the backup file. However, when I run os.listdir(path) in django, the result is empty list. In the other word, I can access to sharedV directory in Django but I can not see its contents! Is there any idea that how can I access to host from a running container? thanks -

Django makemigrations Segmentation fault
I am trying to run a Django rest api in Docker-compose on a raspberry pi 3B with 1gb of RAM. The postgresql database and the nodejs frontend run without any problem. But for the django backend the output of docker-compose up is a segmentation fault: backend | + python3 manage.py makemigrations restapi backend | No changes detected in app 'restapi' backend | scripts/start_server.sh: line 29: 13 Segmentation fault (core dumped) python3 manage.py makemigrations restapi line 29 in start_server.sh refers to: python3 manage.py makemigrations restapi Any ideas where the segfault is coming from or how I could find out what's the problem? Might this be a memory issue? I configured a 8GB swap alongside the 1GB RAM. Would this prevent python to run out of memory? The exact same configuration runs fine on my PC with 8GB RAM so I suppose there isn't a problem with my django models. Edit: if i skip the makemigrations and jump to migrate I also get a segfault: backend | Applying restapi.0001_initial... OK backend | Applying sessions.0001_initial... OK backend | scripts/start_server.sh: line 31: 13 Segmentation fault (core dumped) python3 manage.py migrate
