How To Migrate IntegerField To ForeignKey
I have a legacy database I am migrating towards Django. I have model like this: class MyModel(models.Model): other_id = models.IntegerField() This is an existing table filled with valid data. I want to migrate to class MyModel(models.Model): newbie = models.ForeignKey( OtherModel, on_delete=models.CASCADE, db_constraint=False, db_column="other_id", ) However, the generated migration keeps insisting on adding the already existing field and than dropping it: python manage.py sqlmigrate app 0069 BEGIN; -- -- Add field -- ALTER TABLE `mymodel` ADD COLUMN `other_id` integer DEFAULT 1 NOT NULL; ALTER TABLE `mymodel` ALTER COLUMN `other_id` DROP DEFAULT; -- -- Remove field -- ALTER TABLE `mymodel` DROP COLUMN `other_id`; Is there a way to convince Django to treat the field as ForeignKey without this exercise? I'd like to avoid a need to --fake the migration. -

Django: How do I get referenced objects in a symmetric ManyToMany relationship?
I've created a Many-to-Many relationship for the model UserProfile, to enable users to grant access to a particular feature to one another.

Decoding (and equating) special characters with the Django REST framework SearchFilter?
I have implemented a Django Rest Framework SearchFilter in my backend, which for the most part works correctly. This is the code structure in views.py: class JobsViewSet(viewsets.ModelViewSet): queryset = Jobs.objects.all() serializer_class = JobSerializer filter_backends = [filters.SearchFilter] search_fields = ['^name', '^job_type'] The only remaining problem is that when sending get requests with a special character, for example the Swedish letter å, Django doesn't recognize that å is the same letter as Å only in lower case (as it does with for example a and A). In the GET calls from the front end, å gets converted to %C3%A5 for lowercase and %C3%85 for uppercase. This results in the search box not finding the jobs beginning with the letters åäö if the job title begins in uppercase (as in Återvinning). Does anyone know of a solution that makes the filter understand and equate uppercase and lowercase letters of special characters? Something along the lines of UTF-8 decoding? I have looked for answers both in the REST framework documentation and here on Stack Overflow, without any luck. New to Stack Overflow btw, I hope I'm doing the formatting correctly! -
not able to POST required data in django templates
I want to POST a form from my html to views.py in django, but I am not able do it. This is my html. This form should post the url of the downloaded image to the views.py function. {% for x in photo %} <a class="down" href="{{x.image.url}}" onclick="myfunc()" download="none">get</a> <form action="/image_info/" method="POST" id='dform'> {% csrf_token %} <input name='d_button' type="hidden" value="{{x.image.url}}"> </form> {% endfor %} This is my javascript function to submit form whenever the get link is pressed <script type="text/javascript"> function myfunc() { document.getElementById("dform").submit(); console.log('hello'); } </script> this is my views.py. This should take the image url from the form and display it in the new page. def show_image(): image_url = request.POST.get('d_button', None) return render(request, 'show_image.html', {'image': image_url) but my problem is that the form is not returning the url of the image that is clicked instead it is returning the url of first link. for example link1 link2 link3 link4 if I click on link3, it is downloading the image in link3 but POSTING the url of link1 This is a bit tricky to explain but this is the best I can.

Django many to many field, but display just the highest value

I've setup my django rest framework server in which I want to upload some news alongside their images. Actually I'm able to upload news and images because I retrieve them on my server filesystem, but when I request for a list of news I get an image url which, when pasted in my browser, shows me "The requested resource was not found on this server". Following is reported some code. models.py class News(models.Model): author = models.CharField(max_length=50) title = models.CharField(max_length=150) content = models.CharField(max_length=10000) image = models.ImageField(upload_to='news', blank=True, null=True) created = models.DateField(auto_now_add=True) def __str__(self): return "{}".format(self.title) serializers.py class NewsSerializer(serializers.ModelSerializer): class Meta: model = News fields = '__all__' settings.py MEDIA_URL = "/media/" MEDIA_ROOT = os.path.join(BASE_DIR, 'media') views.py class GetNews(generics.ListAPIView): queryset = News.objects.all() serializer_class = NewsSerializer def post(self, request): author = request.data['author'] title = request.data['title'] content = request.data['content'] try: image = request.data['image'] except KeyError: raise ParseError('Request has no resource file attached') news = News.objects.create(image=image, author=author, title=title, content=content) return Response("News successfully uploaded.", status=status.HTTP_200_OK) def delete(self, request): token = request.META.get('HTTP_AUTHORIZATION') if not check_token(token): return JsonResponse({'message': 'Unauthorized!'}, status=status.HTTP_401_UNAUTHORIZED) news = News.objects.get(id=request.data['id']) news.delete() return JsonResponse({'message': 'News was deleted successfully!'}, status=status.HTTP_204_NO_CONTENT) urls.py urlpatterns = [ ... path('news', views.GetNews.as_view()) ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) -
Django Bootstrap will not let me center this container
I have been trying to center this div container after my navbar so that there is an equal space on both sides of the page. But, it is not working for some reason. Can you guys help please? The post_job.html is the issue. The portion where i display the text is being rendered on the left side with a bit of text going down Here is my code snippet: post_job.html {% load static %} {% include 'recruiter_navigation.html' %} {% block content %} <div class="row"> <div class="col-lg-2 col-md-2 col-sm-12 col-xs-12 hidden-xs hidden-sm full_width"> <h2 style="color: darkblue;" class="text-center">Post an Internship</h2> </div> </div> {% endblock content %} recruiter_navigation.html <div class="container"> {% block content %} {% endblock content %} </div>
