Django: Question regarding queries over a junction table/intermediary model
my question concerns the many-to-many section of the django models docs: It is mentioned there that by using an intermediary model it is possible to query on the intermediary model's attributes like so: Person.objects.filter( group__name='The Beatles', membership__date_joined__gt=date(1961,1,1)) However for the other many-to-many model (Group) a similar query results in a FieldError: # which groups have a person name containing 'Paul'? Group.objects.filter(person__name__contains="Paul") Queries that reference the junction table explicity do work: Person.objects.filter(membership__group__name__contains="The Beatles") Group.objects.filter(membership__person__name__contains="Paul") Shouldn't Group therefore have access to Person via the junction model? -

django rest framework nested categories
it is written in nested categories to categorize products. When we were working with Django itself, to display the nested categories in the navbar section, we used to display both the main and nested categories with the four loop twice. My question is that now that I want to write the code in django rest framework to display the nested categories, in addition to the code below, do I have to do anything else? In fact, the issue that is bothering me is how the nested category is called and displayed by the front-end programmer? my model : class Category(models.Model): name = models.CharField(max_length=200, null=True, blank=True) sub_category = models.ForeignKey('self', on_delete=models.CASCADE, related_name='sub') sub_cat = models.BooleanField(default=False) slug = models.SlugField(allow_unicode=True, unique=True, null=True, blank=True) class Product(models.Model): name = models.CharField(max_length=200, null=True, blank=True) category = models.ManyToManyField(Category, blank=True, related_name='cat_product') unit_price = models.IntegerField() my url : path('category/', views.CategoryListApi.as_view()), path('category/<slug:slug>/', views.CategoryProductsApi.as_view()), my view: class CategoryListApi(generics.ListAPIView): queryset = Category.objects.all() serializer_class = CategorySerializer class CategoryProductsApi(generics.ListAPIView): serializer_class = ProductSerializer def get_queryset(self): products = Product.objects.filter(category__slug=self.kwargs['slug']) return products my serializer: class ProductSerializer(serializers.ModelSerializer): category = serializers.SerializerMethodField() class Meta: model = Product fields = '__all__' def get_category(self, obj): return [cat.name for cat in obj.category.all()] class CategorySerializer(serializers.ModelSerializer): sub_category = serializers.SlugRelatedField(read_only=True, slug_field='name') class Meta: model = Category fields = … -
Trying to make a search/filter dropdown with select2 and ajax. my self defined is_ajax(request) function not working?
I am making a django project where there is a search/filter dropdown for a form. I am using select2 and ajax. It isn't working, and when I try to debug with print statements, it seems that the is_ajax(request) function is not returning true. I know the is_ajax() function was deprecated in JQuery, which is why I defined it myself. However, mine doesn't seem to work either. Here is the portion my view that filters objects: @login_required def job_application_create(request): form = JobApplicationForm() if is_ajax(request): print('TESTING TESTING TESTING TESTING TESTING TESTING TESTING TESTING ') term = request.GET.get('term') companies = Company.objects.filter(name__icontains=term) response_content = list(companies.values()) return JsonResponse(response_content, safe=False) and here is the is_ajax(request) definition: def is_ajax(request): return request.headers.get('x-requested-with') == 'XMLHttpRequest' Here is the JS in the page that has my form: <script> $(document).ready(function () { $('#id_company').select2({ ajax: { url: "{% url 'homepage' %}", dataType: 'json', processResults: function (data) { return { results: $.map(data, function (item) { return {id: item.id, text: item.name}; }) }; } }, minimumInputLength: 1 }); }); </script> -
Django Login Access with token
I am developing a Django project, I have created an API in the same project since other tools should be able to use functions from this project. This method is not working and I need someone who has done a similar thing to assist with a more refined and secured method or point out where am doing wrong. When a user is registered, I create an access token ( md5 has ) for this user and store it in a model, each token has a user foreign key. class AuthToken(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) token = models.TextField() created_date = models.DateField(auto_now_add=True) created_time = models.TimeField(auto_now=True) status = models.IntegerField(default=0) in the API, I have added a function to authenticate the user with the token. When the view to authenticate the user is invoked, what I do is. Check if the token exists. Get the user ( AuthToken.user.username ) Get user password ( AuthToken.user.password) Authenticate these details with Django authenticate I understand this will definitely fail since the password fetched from AuthToken.user.password with be an encrypted one, and passing the encrypted password to Django for authentication will encrypt that and compare again. Below is my API authentication view if module == 'auth': # authentication … -
Postgresql ignoring default value on bulk import
I have a postgres DB running in a docker container. I am trying to bulk import a csv full of postcodes. This is a Django project. As they all refer to the same state - "NSW". That column doesn't exist in the CSV. My Model (This is django) has the following definition for the State column: state = models.CharField(max_length=200, default="NSW", null=False, blank=False) But when I try and execute I get the following error: postgres=# \COPY datacollector_localities(name, postcode) FROM '/postcodes-nsw.csv' DELIMITER ',' CSV HEADER; ERROR: null value in column "state" of relation "datacollector_localities" violates not-null constraint DETAIL: Failing row contains (5, Condobolin, 2877, null). CONTEXT: COPY datacollector_localities, line 2: "Condobolin,2877" I assumed the leaving state out of the column_names list would make postgres use the default. What am I doing wrong? -
Is it possible to add a subquery table to a django queryset?
I am working on a query similar to the one below; I want to create this as a Django queryset for further filtering. select distinct on (id) id, title, weight from (select *, 3 + ts_rank_cd(to_tsvector(title), to_tsquery('sales'), 32) as weight from courses where to_tsvector(title) @@ to_tsquery('sales') union all select *, 2 + similarity(title, 'sales') as weight from courses where title % 'sales') as union_table order by id, weight desc I tried creating it as raw method, but that doesn't allow chaining additional filters and the extra method with the tables argument doesn't allow subqueries. Is there any solution other than using the raw SQL? -

Reason given for failure: CSRF token from POST incorrect.?
Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: CSRF token from POST incorrect. In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. The view function passes a request to the template’s render method. In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL. If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data. The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login. You’re seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed. You can customize this page using the CSRF_FAILURE_VIEW setting. please solve this? Reason given for … -

Python Django: getting data from modal gives <built-in function id> error
I'm trying to get a value from a modal, that gets the value using jQuery from a list. Let's explain. I have a list of objects in an HTML page using a for loop, and in each row, there is a delete button. This delete button launches a confirmation Modal. To get the id of the row and use it in the Modal, I use jQuery: {% for a in objects %} [...] <td><button type="button" class="delete-button" data-name="{{ a.id }}" data-bs-toggle="modal" data-bs-target="#deleteModal">Delete</button></td> [...] {% endfor %} [...] <div class="modal fade" id="deleteModal"> [...] <form action="{% url 'delete_object' %}" method="post"> {% csrf_token %} <input type="hidden" name="object_id" name="object_field" /> <button type="submit">Delete</button> [...] <script> $('.delete-button').click(function() { $('#object_id').html($(this).data('name')) }) </script> Without explaining the urls.py part, let's get straight to the view, which is quite simple: def cancel_request(request): _id = request.POST.get("object_id") obj = Object.objects.get(id=id) obj.status = "Annulé" obj.save() return redirect("home") When I run the modal, I make sure I can see the id value getting in the modal, but when I try to put it in an input, I cannot see it anymore. If I put it in an h5 tag for example: <h5 class="modal-title" id="request_id" name="requestid_kw"></h5>, it shows on the modal, but still does not get … -

I also have checked out OpenWisp, but it does not fit my requirements (too complex). So is there any guide on integrating a django project with FreeRadius and Coovachilli? -

Django redirect /D/<anything> to /d/<anything>
I'm looking for a way to redirect any url that start with /D/ to the same URL with lowercased /d/. /D/<anything_including_url_params> to /d/<anything_including_url_params> I literally only want to redirect urls that start with /D/ - not /DABC/ etc... The suffix can also be empty, eg. /D/ > /d/ Is there a way to do that in Django? It is for a third-party app with urls included in projects urls. The alternative is to use re_path and change: path("d/", include(...)) to re_path(r"^[dD]/$", include(...)) but I'd rather do a redirect instead of this. -

Django images not showing up in template
I've spent the whole day trying to find a solution for showing the images in the template but I couldn't find any solution to my case. This is my settings STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'DataCallGuide/static') ] My model class TroubleshootingSteps(models.Model): box_header = models.CharField(blank=True, null=True, max_length=250) box_content = models.CharField(blank=True, null=True, max_length=250) box_botton = models.CharField(blank=True, null=True, max_length=250) header = models.TextField(blank=True, null=True) sub_header = models.TextField(blank=True, null=True) text1 = models.TextField(blank=True, null=True) image1 = models.ImageField(blank=True, null=True, upload_to="images/") and the template {% extends 'base.html' %} {% load static %} {% block content %} <div class="container overflow-hidden"> <div class="text-center"> <h4 class="mt-5 mb-5">{{data.header}}</h4> </div> <h3 dir="rtl" class="rtlss">{{data.sub_header}}</h3> <img src="{{ data.image1.url }}"> </div> {% endblock%} Also when I click on the image link in admin pages it doesn't show the image and display page not found error with the below link http://127.0.0.1:8000/media/images/IMG-20220901-WA0009.jpg What is wrong please? -
Django IO bound performance drop with gunicorn + gevent
I have been working on an IO bound (only simple queries to database for getting info or updating it) application written in Django. As application is mostly db and redis queries, I decided to use gunicorn with async gevent worker class, but the weird part is that eventhough I'm running gunicorn with gevent (also monkey patched db for that purpose), I'm not seeing any performance gain by it, in fact, both requests/s and response time has dropped. Steps taken To do so, I have done the following: Installed greenlet, gevent & psycogreen as instructed in official docs. Patched postgres with psycogreen.gevent.patch_psycopg (tried wsgi.py, settings.py and post_fork in gunicorn) but to no avail. Tried running gevent's monkey.patch_all manually, also no use. This is my gunicorn.config.py: import gunicorn gunicorn.SERVER_SOFTWARE = "" gunicorn.SERVER = "" bind = "0.0.0.0:8000" worker_class = 'gevent' worker_connections = 1000 # Tested with different values keepalive = 2 # Tested with different values workers = 10 # Tested with different values loglevel = 'info' access_log_format = 'sport %(h)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(f)s" "%(a)s"' def post_fork(server, worker): # also tried pre_fork and on_starting from psycogreen.gevent import patch_psycopg patch_psycopg() Result But the app only got slower, also note …
