Static files won't load
I`ve created a new Django project and ran into a problem with static images. So, apparently when i was connecting my css and javascript files with static it worked well, but when i tried to connect images they won't load. here is my settings.py # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/4.2/howto/static-files/ STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_DIRS = ['static'] # Default primary key field type # https://docs.djangoproject.com/en/4.2/ref/settings/#default-auto-field DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' LOGIN_REDIRECT_URL = '/' urls.py from django.contrib import admin from django.urls import path, include from store import settings urlpatterns = [ path('admin/', admin.site.urls), path('', include('mstore.urls')), ] if settings.DEBUG: from django.conf.urls.static import static urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) here is example of how i display it in template <a href="#" class="item__image"> <picture><source srcset="img/collections/featured/02.webp" type="image/webp"><img src="{% static 'mstore/img/collections/featured/02.png' %}" alt="Lore Walnut"></picture></a> Please, before answering note that i checked the src of the image in browser, and it worked. src of image in browser i copied this link and pasted in browser and got this enter image description here Besides, css and js works great, so i think the problem is in images I tried to run python manage.py collectstatic and it worked perfectly. -

SQL query to find exact words in any order
I have a postgres table Article which has three columns - title, description, categories. All the three columns contain plain text. I have 2 search words - say word1, word2 I want to find the records where title+description+categories contains all the exact search words, in any order. need exact case-insensitive matches. Ex. man shouldn't match against woman. The search words can appear in any order Ex. If we search for "pollution global warming" - it should match against "... global abc warming adds to toxic mix of pollution..." Need help in implementing a procedure(if not possible by query) where we can pass in the list of search words and it should return the list of records. Any pointer will be a great help. On a side note, I intend to consume this in django. If this requirement can be better achieved using django ORM, that should also suffice. -
Why doesn't my javascript work in django?

My html code in Django is as follow: <!DOCTYPE html> <html> <head> {% load static %} <title>Vue.js and Django Integration</title> <script src="{% static 'js/vue.min.js' %}"></script> </head> <body> <div id="app"> <h1>{{ message }}</h1> <input v-model="inputText" type="text"> <p>You typed: {{ inputText }}</p> </div> <script> new Vue({ el: '#app', data: { message: 'Hello from Vue.js!', inputText: '' } }); </script> </body> </html> How can I fix this issue? -

Removing 'Add' link in Django admin sidebar
The Django admin index page lists models in a left side sidebar, each with an 'Add' link to instantiate a new object. I want to remove that 'Add' link for just one of the models (Appointments) in the side bar, while retaining it within inline views. First try: set add_url to false. # admin.py class AppointmentAdmin(admin.ModelAdmin): add_url = False This did not work. The 'Add' link still appears. The docs say add_url is an AdminSite method, but I don't want to apply it site-wide. Second try: override the app_list.html template. This works, but seems like the brute force way. There must be something more elegant? I've looked at defining-a-custom-app-list-in-django-admin-index-page, much more complex, not directly applicable, and uses AdminSite (I'm assuming I need to be working local to this app, i.e. admin.ModelAdmin). {% if app_list %} {% for app in app_list %} <div class="app-{{ app.app_label }} module{% if app.app_url in request.path|urlencode %} current-app{% endif %}"> <table> <caption> <a href="{{ app.app_url }}" class="section" title="{% blocktranslate with name=app.name %}Models in the {{ name }} application{% endblocktranslate %}">{{ app.name }}</a> </caption> {% for model in app.models %} <tr class="model-{{ model.object_name|lower }}{% if model.admin_url in request.path|urlencode %} current-model{% endif %}"> {% if model.admin_url %} <th … -
Cancel create when data is wrong

However, even data is not good, it makes the row in model Drawing. I would like to cancel the creating row too. Is there any way to do this? -
Beget "doesn't see" DEBUG=False
I am hosting my test site on Beget and installed Django on it using CMS. I set the DEBUG=False in settings.py, but I think it "doensn't know" about it, because it's still showing me the Django introduction page, despite the fact that I've changed urls.py too and it must return my template. Also it keeps throwing this error "The Cross-Origin-Opener-Policy header has been ignored, because the URL's origin was untrustworthy. It was defined either in the final response or a redirect. Please deliver the response using the HTTPS protocol. You can also use the 'localhost' origin instead". Now it's trying to fetch 'http://domain/favicon.ico' and it throws 404. I don't know why is it like that. Can someone help me? EDITED: The last 404 error disappeared, lol -

Problem in a customized permission in django rest framework
I tried to make a customized permission class which ensures that the user is authenticated and the authenticated user trying to access the endpoint is accessing information related to him not another user. This is the customized class: from rest_framework.permissions import BasePermission class IsAuthenticatedAndSameUser(BasePermission): def has_object_permission(self, request, view, obj): if request.method == "GET" or request.method == 'DELETE': print(request.user) if request.user.is_authenticated and (request.user == obj.user): return True else: return False I gave the Viewset the new customized class in permission classes. class AccountViewset(viewsets.ModelViewSet): queryset = Account.objects.all() serializer_class = AccountSerializer authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticatedAndSameUser,) @action(detail=True, methods=['get'], permission_classes=(IsAuthenticatedAndSameUser, )) def orders(self, request, pk, *args, **kwargs): The permission class works fine when I try to access endpoints related to the Account model directly like: http://127.0.0.1:8000/api/accounts/2/ But it doesn't work as expected on the action decorator. When I use the endpoint related to the action decorator: http://127.0.0.1:8000/api/accounts/2/orders/. The class uses the has_permission function instead of has_object_permission function in IsAuthenticatedAndSameUser class. I want it to use the has_object_permission function.

They'll choose an option, and upon submission, the selected value will update multiple rows. Currently, I've managed to create this functionality, but I'm encountering an issue. When the form submits and redirects back to the admin interface, the selected value isn't present in the request's POST data. model.py: class Intervencao(models.Model): .... responsavel = models.ForeignKey(Responsavel, blank=True, null=True, on_delete=models.CASCADE,verbose_name="Responsavel") ..... class Responsavel(models.Model): nome = models.CharField("Responsável", max_length=200) admin.py: class IntervencaoAdmin(admin.ModelAdmin): .... def assign_all_view(self, request, queryset): form = AssignResponsavelForm(request.POST or None) print("POST data:", request.POST) # Debug: Print the entire POST data print("new_responsavel_id:", request.POST.get('new_responsavel')) # Debug: Print the new_responsavel_id if request.method == 'POST': if form.is_valid(): new_responsavel = form.cleaned_data['new_responsavel'] selected_items = form.cleaned_data['selected_items'] # Debug print statements print("New Responsável ID:", new_responsavel.id) print("Selected Items:", selected_items) Intervencao.objects.filter(pk__in=selected_items).update(responsavel=new_responsavel) # Debug message print("Responsável updated successfully") context = { 'form': form, 'queryset': queryset, } return render(request, 'admin/assign_all_view.html', context) actions = [assign_all_view] form.py class AssignResponsavelForm(forms.Form): new_responsavel = forms.ModelChoiceField(queryset=Responsavel.objects.all(), label="Novo Responsável") selected_items = forms.ModelMultipleChoiceField(queryset=Responsavel.objects.all(), widget=forms.MultipleHiddenInput()) assign_all_view.html {% load static %} {% block content %} <div class="module"> <h2>Trocar de Responsável</h2> <form method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" value="Trocar Responsável" class="default" … -

Django db not updating using Docker on production
Using Django and Postgres for my project, I can't update my database on the production environment. I also tried running migration commands manually on the server, but it doesn't seem to work, as it always says the migrations are already applied and no changes are detected. When I check the migrations folder, I can see my new changes are specifically written, but the migrations aren't applied because I get a db error when I open the django admin panel; so I have no choice but to run docker compose down -v to delete the db and start fresh. (which is terrible cause I loose all my db records) I believe it might be a cause of ignoring my migrations files, so the only things pushed to the server are regular files and migrations/__init__.py, so django can detect the app and apply the migrations. Note that pushing all my migrations files to the server is not an option, because it's not efficient to go through all the changes I had in my local environment. Is there any way I can solve this problem?
