Caching Django Rest Framework function-based view causes permission classes to be ignored
I'm having a strange issue where my function-based view caching seems to be conflicting with the permission classes applied to it. The decorators for the view are as follows: @cache_page(3600) @api_view(['GET']) @permission_classes((APIKeyPermission,)) def function_based_view(request): # function-based view code here... The problem is: When I try to access the view via HTTP GET, if it is not yet cached, it will require the APIKeyPermission to be satisfied and give me a 403 error. This is correct behavior. Once the view has been successfully cached, any HTTP GET request can successfully access the view without providing any required permissions. It is important to note that once the view is cached, the @permission_classes decorator seems to do nothing and the view does not even fall back to the DEFAULT_PERMISSION_CLASSES as specified in settings.py (which in this case are even more strict than the single permission class specified in the @permission_classes method decorator.) In short: Once the view is cached, it can be accessed without any of the permission classes being applied to it. How do I fix this so that the permission classes are properly applied to cached views? -
request.FILES.get is returning None
I was developing my website, just when I realized that the update_supplier view stopped working correctly. In this view I update the name and the image. For some reason it is only getting the name and not the image from the request. When I try to print request.FILES it returns a empty multidictionary. <MultiValueDict: {}> This is my form: {% for supplier in all_suppliers %} <div class="modal fade" id="staticSupplierUpdate{{ supplier.id }}" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h1 class="modal-title fs-5" id="staticBackdropLabel">Editar Fornecedor</h1> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> <form id="update_supplier_form" method="post" action="{% url 'update-supplier' supplier.id %}" enctype="multipart/form-data"> {% csrf_token %} <div class="form-group"> <label class="label_form_create_project d-flex text-left" for="update_supplier_name{{ supplier.id }}">Nome:</label> <input type="text" id="update_supplier_name{{ supplier.id }}" name="update_supplier_name" value="{{ supplier.name_supplier }}" required> </div> <div class="form-group"> <label class="label_form_create_project d-flex text-left" for="update_supplier_image{{ supplier.pk }}">Imagem do fornecedor:</label> <div class="custom-file"> <input type="file" id="update_supplier_image{{ supplier.pk }}" class="custom-file-input" name="update_supplier_image" accept=".png, .jpg, .jpeg" onchange="previewImageSupplierUpdate(this, '{{ supplier.pk }}')"> <label class="custom-file-label custom-file-label-update-supplier" for="update_supplier_image{{ supplier.pk }}">Escolha uma imagem</label> </div> <img id="imagePreview{{ supplier.pk }}" src="{{ supplier.image_supplier.url }}" alt="Image Preview" style="max-width: 200px; max-height: 200px; margin-top: 10px; "> </div> <button type="submit" class="btn btn-primary save_project">Salvar</button> </form> <form id="deleteSupplierForm" action="{% url 'delete-supplier' 0 %}" method="post" style="display: inline;"> {% csrf_token %} <input … -

GeoDjango automatically transforming my coordinates
I have an API using GeoDjango and PostGIS. Every time I try to add a post with a point it gets saved as another point around 10,000 times less than the values I entered for both latitude and longitude.

When needing to count likes, views, etc per post whats the better approach?
I’m making an app using django where users can make posts. To add likes and views which can be counted and sent to be displayed on frontend i’m thinking of two approaches. is to use a reverse foreign-key relation between post’s model and likes model to dynamically count the instances of the likes model each each time. So create/delete instances of like model to represent like/unlike is to use a integer field model to store the counts in the database. use many-to-many field where number if likes for a post is determined my NO. Of user instances associated with post.likes Which approach does instagram use? Which approach would be the ultimate choice? Considering keeping costs low while maintaining scalability possibilities. Thanks -
Is it OK use multiple empty routes in Django URL patterns?
One of my project's app's url.py includes url files from other apps. Is there any issue I'm overlooking by including them with empty routes? e.g.: In appA urls.py: urlpatterns = [ path('hub/', views.hub, name='hub'), path('dashboard/', views.dashboard, name='dashboard'), path('', views.hub_redirect), # Redirects / to /hub/ path('', include('appB.urls')), path('', include('appC.urls')), ] Where appB.urls and appC.urls all contain paths each with a defined unique route (i.e., not ''). It works! But now wondering if it should... I've not seen any documentation saying that non-empty routes are required, but concerned now about best practice. I'm also concerned that I'm not understanding the function of apps. When I use django-admin createapp the urls.py is not automatically generated, so it makes me wonder if I should keep urls all on appA and point them to the views of appB and appC, but my current way makes sense to me (as it would be easier to refactor a URL within the app of the related functionality without having to make changes ouside, i.e. in appA). -

How can I make a drop-down field to display a record in a database in Django. e.g. If I select a Last Name it displays the associated record
I am trying to display a record of a database after a user has selected the record from a dropdown list of one of the fields of the table (in Django). So far I have only seen examples of selecting data from other tables. I have a model:class Customer(models.Model): created_at = models.DateTimeField(auto_now_add=True) customer_number = models.AutoField(primary_key=True) business_name = models.CharField(max_length=75, null=True, blank=True) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) email = models.CharField(max_length=100, null=True, blank=True) and a view: def customer_record(request): customers = Customer.objects.all() return render(request, 'customer_record.html', {'customers':customers}) and a form class Meta: model = Customer fields = ('customer_number', 'business_name', 'first_name', 'last_name', 'email') labels = {'business_name':'', 'first_name':'', 'last_name':'', 'email':'',} and the html: <select class="form-select" aria-label="Default select example"> <option selected>Open this select menu</option> {% if customers %} {% for customer in customers %} <option value={{ customer.last_name }} ></option> {% endfor %} {% endif %} </select> Trying the above, I get the dropdown that says: "Open the select menu", and then blank spaces in the dropdown corresponding, I believe, to the number of records I have. I expected to see the last names appear in the dropdown. Once selected, I would like to then display the record. -
Getting nested models fields. Serializer error. Object of type QuerySet is not JSON serializable

I am trying to work on a website that needs custom user so I have inherited AbstractUser class to make my own custom user model, I am using Django built in authentication - log in / sign up as well and am able to do this successfully and store it and retrieve back in MySql database. Now my problem - I need to create users that can be tied as a family as this will be for a gym.

Basically what is the best practice - how to create models for this situation? If anyone can point me to right direction please ? -
Cannot insert the value NULL into column 'id', table 'table'; column does not allow nulls. INSERT fails
I created a new table in Django to save some data. When I implemented the save view function, it worked locally. When it was published to the testing enviroment, I got the error Cannot insert the value NULL into column 'id', table 'table'; column does not allow nulls. INSERT fails. From what ive been able to see through the searches ive done, and queries on Azure, the auto-increment feature is not working. I tried this query and got the following results SELECT COLUMN_NAME, COLUMN_DEFAULT, DATA_TYPE, IS_NULLABLE, COLUMNPROPERTY(object_id(TABLE_NAME), COLUMN_NAME, 'IsIdentity') FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'table' AND COLUMN_NAME = 'id'; COLUMN NAME Column B DATA_TYPE IS_NULLABLE id int NO 0 I have tried to manually change the IDENTITY to 1, but it didnt work. I got errors preventing this. Failed to execute query. I am not able to manually add a row in Django Admin, as I get the same error, and there are no entries to the table in the database at all. -

Django not creating a table in the Development Server
I've been trying to fix this problem, but couldn't find a solution, tried a bunch of fixes online. The problem I'm facing. I have a Django project running on Hawuei Cloud, I've made some changes and wanted to test it on the Development server before going to production. The project is running fine, BUT, there's a table that is not being created for some reason, so the parts of the project that uses that table, throws an error. But the thing is the changes I've made weren't on that table. I don't understand why that table isn't being created, I never had this issue. This is a small part of the model class Regime(models.Model): inventario = models.ForeignKey(Inventario, on_delete=models.CASCADE) nome = models.CharField(max_length=50) def __str__(self): return self.nome class Unidade(models.Model): empresa = models.ForeignKey(Empresa, on_delete=models.CASCADE) codigo = models.CharField(max_length=50) descricao = models.CharField(max_length=100) cnpj = models.CharField(max_length=20) def __str__(self): return self.descricao class Conta(models.Model): empresa = models.ForeignKey(Empresa, on_delete=models.CASCADE) codigo = models.CharField(max_length=50) descricao = models.CharField(max_length=100) def __str__(self): return self.descricao class Local(models.Model): empresa = models.ForeignKey(Empresa, on_delete=models.CASCADE) codigo = models.CharField(max_length=50) descricao = models.CharField(max_length=100) def __str__(self): return self.descricao The table Unidade is not being created, the other similar ones like Local and Conta work just fine.

Problem with django translation detection in the templates
Here i generate my template from a http request so i have a custom method to generate my templates : def get_template(template, using=None): engines = _engine_list(using) for engine in engines: return engine.from_string(template) And here i pass the template : def get_template_names(self): print(self.html_template) return get_template(self.html_template, using=self.template_engine) and in my console i get : app-1 | {% load i18n static %} app-1 | app-1 | {%block content %} app-1 | <p>{{ _('Hello from the template')}}</p> app-1 | <p>{% translate 'hello my friends' %}</p> app-1 | app-1 | {%endblock%} Then i generate my .po file insinde a locale dir with django-admin makemessages -l fr So the problem is when the .po file is generated i don't get my strings Hello from the template and hello my friends while we are supposed to get the strings to translate automatically.

This is work well Where is the problem please I don't want to add strings manually anymore ? i try to get my custom strings to translate inside my custom template but i don't get them the .po file is empty -
How to change the attributes of Django login form
My site is RTL so I need to adjust the direction of some fields to LTR (username, email, password, etc). One of them is the Password Change form so this is what I do: forms.py from django.contrib.auth.forms import PasswordChangeForm class CustomPasswordChangeForm(PasswordChangeForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['old_password'].widget.attrs.update({'dir': 'ltr'}) self.fields['new_password1'].widget.attrs.update({'dir': 'ltr'}) self.fields['new_password2'].widget.attrs.update({'dir': 'ltr'}) After creating the required view and URL path, that works perfectly and all 3 fields are LTR. The other one is the Login Form so I do the same thing: forms.py from django.contrib.auth.forms import AuthenticationForm class CustomAuthenticationForm(AuthenticationForm): def __init__(self, request=None, *args, **kwargs): super().__init__(request, *args, **kwargs) self.fields['username'].widget.attrs.update({'dir': 'ltr'}) self.fields['password'].widget.attrs.update({'dir': 'ltr'}) This time, the above code does not have any effect. Both fields are still RTL. So why it works for password change and not for login and what's the solution for login form? -
