Search Django logic
I have written the following code on my web app for searching the form. Now, I want to show error if the searched object if not found. I added the else statement at the last but it shows error. def search(request): qs = Post.objects.all() location_query= request.GET.get('location') details_query= request.GET.get('details') user_query= request.GET.get('user') days_query= request.GET.get('days') people_query= request.GET.get('people') date_query= request.GET.get('date') gender_query= request.GET.get('gender') if location_query !='' and location_query is not None: qs=qs.filter(location__icontains=location_query) elif details_query !='' and details_query is not None: qs=qs.filter(detail__icontains=details_query) elif user_query !='' and user_query is not None: qs=qs.filter(author__icontains=user_query) elif days_query !='' and days_query is not None: qs=qs.filter(no_days__icontains=days_query) elif people_query !='' and people_query is not None: qs=qs.filter(no_people__icontains=people_query) elif date_query !='' and date_query is not None: qs=qs.filter(tour_date__icontains=date_query) elif gender_query !='' and gender_query is not None: qs=qs.filter(Gender_prefer__icontains=gender_query) context = { 'qs':qs, } return render(request, 'posts/search.html',context) I am trying to add this at the end: return render(request, 'posts/search.html', {'error':'The keyword you entered not found!}) -
how do i generate Django site-map without model
i have searched google a lot and read many articles and docs. but all shows how to create sitemap in django useing from django.contrib.sitemaps.views import sitemap but the problem is they all generate sitemaps on top of model(table). i have a database of images( 20,000 images ) they all have different pages and their link generated manually like... path('image/<str:name>/<str:size>/', views.image, name="image"), also my site have many static pages like about us and contact us. also many image gallery pages. so the site have thousands of urls. the image database changes frequently so url changes too how do i generate xml sitemap for this situation. or maybe there is a way around with 3rd party plug in? -

On submit a Django ChoiceField form only returns the first dictionary in the formset
I have defined a formset that has 3 forms in the following order. Type Number (Student ID) Type Text (Course Name) View.py for form in formset: if form.has_changed(): print(form.cleaned_data) When a post request is submitted the formset.cleaned_data returns [{'student_id': 1, 'course_name': 'English'}, {'student_id': 2, 'course_name': 'Math'}, {'student_id': 3, 'course_name': 'PE'}] I have also added a check if a form.has_changed(), so if I submit 'History' instead of 'English' where id is equal to 1 my form.cleaned_data returns the expected dictionary. {'student_id': 1, 'course_name': 'History'} My issue: When I had a type text form for 'course_name' everything was working as intended. I only faced an issue when I changed the text form to be single-select instead, so the formset is as follows: Type Number (Student ID) Type ChoiceField (Course Name) The formset.cleaned_data returns the same list of dictionaries. [{'student_id': 1, 'course_name': 'English'}, {'student_id': 2, 'course_name': 'Math'}, {'student_id': 3, 'course_name': 'PE'}] However, if I submit 'History' to change the 'PE' course where id is equal to 3 the form.cleaned_data always returns the first dictionary in the list. {'student_id': 1, 'course_name': 'English'} Why is this happening? Is there any issue with using ChoiceField in the formset? -

Serve a django specific url on a different domain on GKE
I have a django application deployed on GKE. I use drf-spectacular to generate an open api documentation. The documentation is available under a specific path and I would like to serve this documentation to a specific domain. To be more specific, my app is under api.my-domain.io, I reserved another domain as docs.my-domain.io, what I want is docs.my-domain.io to 'redirect' to api.my-domain.io/my-open-api-doc.

time data '2021-06-10T18:39:41 10:00' does not match format '%Y-%m-%dT%H:%M:%S %z'

Reactjs frontend with PasswordResetView
I am currently working on a reset password feature (sends email) for a project that's written in Django backend, Reactjs frontend. I am using Django's own PasswordResetView to implement this feature and it works as intended. However I want a page on my frontend sending a POST request to "reset_password/", but I'm getting a "POST http://localhost:8000/user/reset_password/ 403 (Forbidden)" error message. I don't want to use a template to implement this feature, but a Form (component) written in Reactjs running on localhost:3000. How can I do this? Or should I try another approach to the reset password feature? This is the function that tries to post to backend: async resetPassword(email) { const resetPasswordResponse = await client.post("reset_password/", { email: email, }); return resetPasswordResponse;} -

Ajax, refresh table rows on new additions
I'm working on a Django project that runs a background task every time a form is submitted. It takes roughly 2sec to complete each task, when completed, the results are saved, ajax is supposed to perform page refresh but not the whole page, and what I have so far is: $.ajax({ success: function(){ setInterval('location.reload()', 10000); } }) It works as intended, but it's wrong. I have rather limited experience with js. However, I'd like to refresh only the newly added row(s) in the table. I came across jquery .load() but I've been staring for a while now, please any help? -
