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?
I am trying to run a simple html file using VUE framework: <!DOCTYPE html> <html> <head> <title>Vue.js Example</title> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.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> It works perfectly fine but when I put the same html into a Django framework, the h1 tag and the inputText area does not show at all. 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? -
Update user profile in Django
I wanted to make an update profile function where users can update their data by filling out a form. My website is running well without any errors, but whenever I fill up the form & hit submit the profile doesn't update itself & also new data is not saved. Here is the code: views.py: def updateProfile(request): if request.method == 'POST': profile_form = updateProfile(request.POST, instance=request.user.profile) if profile_form.is_valid(): profile_form.save() return redirect('profile') else: profile_form = UserProfile(instance=request.user.profile) return render(request, 'profile.html', {'profile_form': profile_form}) Please check out my function. -
Join Query in Django ORM to Create Report
I have the following models structure: class Student(models.Model): full_name = models.CharField(max_length=100) std_class = models.CharField(max_length=50) class Teacher(models.Model): full_name = models.CharField(max_length=100, unique=True) class Attendance(models.Model): att_date = models.DateField(default=date.today) teacher = models.ManyToManyField(Teacher) subject_name = models.CharField(max_length=50) std_class = models.CharField(max_length=50) total_students = models.IntegerField(default=0) class Entry(models.Model): attendance = models.ForeignKey(Attendance, on_delete=models.CASCADE) student = models.ForeignKey(Student, on_delete=models.CASCADE) I want to build a report like below for all students in the given class: Student Name Attendance Date 1,Teachers Name Attendance Date 2,Teachers Name ... Student 1 P A ... Student 2 A P ... Student 3 P P ... ... ... ... ... Student N A A ... The P (Present) should be marked if Entry has a row that contained attendance for a given student otherwise A (Absent). I've built the code and it working correctly, but it is very inefficient. report_dict = {} all_students = Student.objects.filter(std_class=class_full_name) for name in all_students: report_dict[name.full_name] = [] attendance_list = Attendance.objects.filter(Q(std_class=class_full_name) & Q(att_date__month=curr_month)).order_by('att_date') for rec in attendance_list: # Make absent all student initially for key in report_dict: report_dict[key].append("A") # Get all attendance for current attendance id entries = Entry.objects.filter(attendance=rec) # Mark present to the selected student for e in entries: if report_dict[str(e.student)] != None: report_dict[str(e.student)][-1] = "P" Is there a better approach to solving … -
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
I have this class view which is connected to Model class DrawingViewSet(viewsets.ModelViewSet): queryset = m.Drawing.objects.all() serializer_class = s.DrawingSerializer def create(self, request, *args, **kwargs): request.data._mutable = True request.data['update_user'] = request.user.id request.data['create_user'] = request.user.id try: isDataGood(request.data) except: logger.error("data is not good") return Response(data={'error': 'This file is not pdf'}, status=406) In create method, I check the data in isDataGood and then return error when data is not good. 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.

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?
