How to upadate a text for H2 tag from views.py in django
I have the buttons defined in html file. When I click on the button iam sending the name of the button using post request using Ajax and getting it to the views.py , saving it in 'catogory_type'. When iam printing it in the terminal, it is getting printed. But when iam rendering the page, that H2 tag is showing empty without any text. How can I print that value in the page when I clicked on the button. Asper my understanding, after clicking the button in the page, it is not getting reloaded. Iam not sure how to refresh the page to re-render it with updated data again. Please suggest me on this. Thanks:) Need to get the the page refresh with updated data in django. -
python django factory set random locale and then create model based on this locale
I would like to create test models of people of different nationalities. During creation, factory would randomly select nationality from a list of "locale" attributes. It would then determine personal attributes based on the previously drawn nationality. Here is my code, which does not work. It mixes attributes of different nationalities class PersonModelFactory(factory.django.DjangoModelFactory): locale = factory.fuzzy.FuzzyChoice(["cs_CZ", "da_DK", "de_DE", "en_GB", "es_ES", "fr_FR", "hr_HR", "hu_HU", "it_IT", "nl_NL", "no_NO", "pt_BR", "pt_PT", "ro_RO", "sk_SK", "fr_CH", "pl_PL", "de_AT", "es_AR"]) class Meta: model = Person exclude = ("locale",) first_name = factory.Faker("first_name_male", locale=locale) last_name = factory.Faker("last_name_male", locale=locale) nationality = factory.Faker("current_country", locale=locale) ...and so on... In addition, it would be best if half of the people could be British, another half as other mixed nationalities. I tried this code to do so: locale = factory.fuzzy.FuzzyChoice(["en_GB", None]) if locale is None: locale = factory.fuzzy.FuzzyChoice([...]) Unfortunately, only the first line of code is is read and the program only chooses between en_GB and None (which is en_US by default). If statement is ignored. -

Errno 13 Permission denied: 'images' on Production environment
I'm facing an issue with file permissions when trying to access an AWS S3 bucket in my Django application. Everything works perfectly in my local development environment. However, when I deploy the application to my production environment, I encounter a "Permission Denied" error when trying to read/write from the 'images' directory in the S3 bucket. Locally, I see successful GET and POST requests in my logs, and the S3 URLs are generated as expected. In production, I get an error message saying "Exception in generate_diamond_painting_preview: [Errno 13] Permission denied: 'images'." I've checked my IAM policies and S3 bucket policies, and they seem to allow for the necessary actions. I'm at a loss for what could be causing this discrepancy between my local and production environments. Local Environment Testing: Verified that the S3 bucket interaction works as expected in my local development environment. Files are read and written without any issues. AWS IAM Policy: Reviewed the IAM policy attached to the role/user used by the Django application. The policy allows for full S3 access to the specific bucket and its contents (s3:*). Server Logs: Checked the logs in the production environment to pinpoint the error, which led me to the "Permission … -
Django forms Choicefield parameter session key
I am working on a project which bases operations on the session_key parameter. I would like to fetch data from the database and add the variables into a choicefield in forms. Using the ModelChoiceField(queryset=..., empty_label="(Nothing)") could be an option, but i still cant take in the session_key as a parameter to filter the queryset. so my question, how can i fetch the session_key from the request in views and pass it to the queryset in the forms class? Thx! -
Django Admin: IntegrityError When Adding New or Modifying Existing Models From Django Admin Panel in Browser
I'm encountering a peculiar issue when attempting to add or update existing models through the Django Admin panel. It results in the following error: IntegrityError at /admin/main/user/2/change/ FOREIGN KEY constraint failed Here are the details: Django Version: 4.2.4 Exception Type: IntegrityError Exception Value: FOREIGN KEY constraint failed Exception Location: C:\Users\Administrator\Desktop\oracle\Site #041\site\env\Lib\site-packages\django\db\backends\base\base.py, line 313, in _commit Occurred during: django.contrib.admin.options.change_view Python Version: 3.12.0 Python Executable: C:\Users\Administrator\Desktop\oracle\Site #041\site\env\Scripts\python.exe This error happens when I try to update or add data to an existing model. However, it's worth noting that when I update or add new data using my custom admin interface, everything works as expected. I'm seeking assistance in understanding the root cause of this issue and how to resolve it. Any guidance would be greatly appreciated. -

How to generate server code from an OpenAPI Specification (OAS) in Django Rest Framework?
I'm working on a Django Rest Framework project, and I have an OpenAPI Specification (OAS) file that I'd like to use for code generation. My goal is to automatically generate API endpoints, serializers, and views from this OAS file. I'm seeking guidance on how to generate Django Rest Framework code (serializers, views, URLs) based on the OAS file. I'd like to know which tools or libraries are commonly used for this purpose and any steps or configurations I need to follow. Additionally, any tips or best practices for integrating OAS with Django Rest Framework would be greatly appreciated. I've read through the documentation for Django Rest Framework and searched for relevant resources online, but I haven't found a clear path for integrating OAS with Django Rest Framework. Thank you for any guidance or suggestions you can provide! https://spec.openapis.org/oas/v3.1.0 -

Storing 'formattable' strings in database
I'm working on a project where I need to store certain descriptions in a database. These descriptions need to be strings akin to prepared statements in SQL, where I can later 'inject' my own values wherever necessary. The reason is that the data that goes in the fields needs to be generated by the backend on demand (also the descriptions will potentially be localized later on). Currently I'm simply storing the descriptions in the form of "This is the description for {} and {}" and in the backend I call .format on it to pass the generated values. It's probably worth noting that the user can't interact with this procedure, meaning it shouldn't really be a security hole. However, is there a better way of doing this in Django? Or is my design somehow flawed? Thanks. -
Maintaning isolation between modules in Django monolith
In our company, we have a monolith. Right now is not that big but we are already seeing some problems with the isolation between the modules we have. Our setup is pretty similar to other Django backends: we have a common User model and another UserProfile model where we store additional information about the user. As an additional thing, we also have a company model to group our users by company. These models are shared across all the modules, at least they are coupled as foreign keys in the models of the rest of the modules. They are contained in a companies module, where we have our business rules about how many users a company can have, invariants in their profile, etc. I think this is fine because we usually just do simple and fast join by user ID or filter by it, so we treat this dependency as read-only so we don't skip any business rules/boundaries related to the companies module. My problem comes when, for instance, some moduleA, needs to trigger an application service in moduleB. For instance, let's say moduleB needs to access a resource in moduleA. The code would be something like: # The GetResourceInterface is … -
Django Migrations are not Migrating on production

What is the best approach to handle long tasks in a django app
So I have one function where clients uploads files and does a little parsing and then proceeds to send these results using another API. Now each file takes around 30 seconds to complete and a large deal of that is a POST request im making and awaiting an answer for 25 seconds. My initial solution was that when a client sent a request about this particular function of my app I'd just loop through all those files until the task was completed and then sent back a http response. Of course I noticed that I started getting 504 error because it was taking too long. My second, and current, solution is to respond with a http response immediately containing an empty html page where I then use javascript to use fetch to make calls to this function(a django view) and continually update the page and tell the client that a file has been processed. I also introduced threads to this solution and to my surprise it made it a lot faster, I suppose that is because each thread can get to that point where it waits for the long POST request so going from one to two almost doubled the … -

simplejwt token work for all tenants for django-tenants
I just want to mention about my problem. I have already researched many documents but I could not find any solution. I just try to use django-tenants. Everything seems OK. But If any user gets the token after login, that token works for all tenants. It's a big leak of security. I have been thinking about an idea SIGNING_KEY. If I can change SIGNING_KEY for each tenant, it may be fixed. But It did not. class TenantJWTAuthenticationMiddleware(MiddlewareMixin): def process_request(self, request): tenant = Client.objects.get(schema_name=connection.schema_name) jwt_secret_key = tenant.jwt_secret_key settings.SIMPLE_JWT['SIGNING_KEY'] = jwt_secret_key This is my Middleware to change SIGNING_KEY for each tenant. class Client(TenantMixin): name = models.CharField(max_length=100) paid_until = models.DateField() on_trial = models.BooleanField() created_on = models.DateField(auto_now_add=True) jwt_secret_key = models.CharField(max_length=100, null=True, blank=True) # default true, schema will be automatically created and synced when it is saved auto_create_schema = True class Domain(DomainMixin): pass This is my model. So, I added jwt_secret_key into my model and I got this field in Middleware and tried to set SIGNING_KEY for jwt. But still, jwt after user login can be used for all tenants. Does anyone have any idea about my problem? Any suggestion or amendment to my solution? Thanks. -
how to refresh the page without reloading, using django, ajax, jquerry?
So I am trying to delete products from cart without refreshing the entire page, I can delete an item and then I need to reload the page to delete another item. I am using Django, jQuery and AJAX to attain the desired result after going through questions of similar nature. In another branch I have implemented the auto refresh feature, whereby after deletion the page automatically reloads but it is not a great user experience. Any help will be greatly appreciated. here's my views.py delete item from cart function def delete_item_from_cart(request): cart_total_amt = 0 product_id = str(request.GET['id']) if 'cart_data_obj' in request.session: if product_id in request.session['cart_data_obj']: cart_data = request.session['cart_data_obj'] del request.session['cart_data_obj'][product_id] request.session['cart_data_obj'] = cart_data if 'cart_data_obj' in request.session: for p_id, item in request.session['cart_data_obj'].items(): cart_total_amt += int(item['qty']) * float(item['price']) context = render_to_string("core/async/cart-list.html", {"cart_data":request.session['cart_data_obj'], 'totalCartItems':len(request.session['cart_data_obj']), 'cart_total_amount':cart_total_amt}) return JsonResponse({"data":context, "totalCartItems":len(request.session['cart_data_obj'])}) here's my function.js implementation $(document).ready(function(){ $(".delete-product").on("click", function(){ let product_id = $(this).attr("data-product") let this_val = $(this) console.log(product_id); console.log(this_val); $.ajax({ url:'/delete-from-cart', data:{ 'id':product_id }, dataType: 'json', beforeSend: function(){ console.log("IN before send"); this_val.hide() console.log("IN after send"); }, success: function(response){ console.log("Starting success"); this_val.show() $("#cart-items-count").text(response.totalCartItems) $("#cart-list").html(response.data) console.log("successfully removed"); }, error: function(response){ alert('error'); } }) }) }) To be able to delete the next item in the cart without refreshing … -
Redirect Django TemplateDoesNotExist to 404
When the template does not exist, a 500 error returns to the user. I want Django to redirect to the 404 page for any view that gets a TemplateDoesNotExistError. Is there a way to accomplish this?
