Integrity error: null value in column violates constraint
I have a ;django view set. I added the create method to my viewset to create new instances and objects to store them. I have 6 fields in the model that include version, path, namespace, value, user_id, and person(ForeignKey) When i open the django rest framework backend page and attempt to create preference, it throws the following error: DETAIL: Failing row contains (20, 1, , , , 1, null). and when i create the object I am adding all of the correct fields so i am not sure why it is throwing null at then end. @permission_classes((IsAuthenticated)) def create(self, request, *args, **kwargs): # switch user_id value with logged in users id queryset = Preference.objects.create() serializer = PreferenceSerializer(queryset, many=True) return Response(serializer.data) I want to be able to create a new preference without an error. -
Exporting data to a tab delimited file from Django
I have exported a .csv file using the csv library of Python and it has a huge amount of columns and data that I want to be able to tab so its more easy to read. Is there some kind of way to deal with this? I'm guessing something like writerow() but for tabs? For example: Tab One: Name and Emails for people with more than 20 years Tab Two: Name and Emails for people with more than 30 years Tab Three: Name and Emails for people with more than 40 years -
AJAX GET Request Being Ignored
I am brand new to AJAX requests and I am still learning Django, but I have a project where the user enters an Elasticsearch query and then we generate a downloadable document (report) for the user. I have an AJAX request to continuously check on the existence of a file in my form.html file and it doesn't seem to be getting picked up at all. I can tell this because it isn't giving me any alerts and it's just automatically timing out on big requests after ~30 seconds. I tried to write a temporary fix in my views.py that is basically attempting to do what the javascript in form.html is doing, but A) I feel like this isn't the best method to use in production, B) it doesn't feel like a good use of time to essentially re-invent the wheel, and C) I want the user to get some sort of alert or indication on their end that the report is in progress, and then when it's ready to download. How can I modify my code to actually perform the AJAX request? Or why does it appear that the AJAX request isn't working? urls.py urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', … -
Fetch request on React with redirect in Django is blocked due to CORS
I am trying to use Spotify authentication in my app. The backend works without any problems on its own, but with React I get an error. In React frontend app, there is a button which makes a successful request to my Django app. For Spotify authentication, I have to create a URL and redirect the request to Spotify API. Spotify has a redirect URI which they use to pass authentication code to the user. I have another endpoint in my Django app to process the authentication code. The first endpoint is /api/v1/login and the redirect endpoint is /api/v1/login_complete on my app. The first endpoint redirects the request to https://accounts.spotify.com/authorize?client_id=*** and Spotify redirects it back to the Login Complete endpoint. The process works without any problems when I try it by directly going to /api/v1/login on my browser. On React, however, I get blocked by the following error: Access to fetch at 'https://accounts.spotify.com/authorize?client_id=CLIENT_ID&response_type=code&redirect_uri=http://127.0.0.1:8000/api/v1/login_complete&state=STATE&scope=user-top-read' (redirected from 'http://127.0.0.1:8000/api/v1/login') from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

How to use "LIKE" on "FROM" clause in sql
I am trying to query a specific table based on a user input, and want to query the table that contains that user input as the search_id in the name. For example, the table names are structured as run_000000_search_000000_lda_000000 and I want to get the table that has the same search_id as the on they put in. I know when "LIKE" is used on the Where clause you can get a column with a specific string or int in the name. However, I have found nothing on using it with the "FROM" clause. Specific hardcoded query for search_id 50 SELECT * FROM `run_000044_search_000050_lda_000366`; In summary, how can I get the table that has the same search_id as the one the user put in. Also trying to use the run and lda to form a full table name does not work because there is no noticeable pattern in between the 3 names. -

How to Save User Input (Django)
I have a dropdown menu which is populated through the combination of two different object values contact.firstName and contact.lastName. How can I submit these two values separately on POST so I can query them at a later time? This issue arose because I need to handle when a first name or last name is more than one word. views.py if form.is_valid(): obj.contact = request.POST.get('select_contacts') template.html <div class="select"> <select name="select_contacts" id="select_contacts" required> <option value="">Contact</option> % for contact in contacts %} <option value="{{ contact.firstName }} {{ contact.lastName }}" name="selected_contact" id="selected_contact">{{ contact.firstName }} {{ contact.lastName }}</option> {% endfor %} </select> </div> -

Is it possible to capture a cache timeout in Django?
I would like to adopt the Django cache system to put an object in cache with let's say a 60 seconds timeout. Every time a cache hit happens such timeout is reset back to 60 seconds. This should work fine but the problem is that I would also like to do something when the timeout occurs. Is that even possibile with cache? -

How should a view function to have a get that post data ? How to process user input and save it ? with view to each input processed/preprocessed?
So I'm working on an app where users can upload images and I can process the images using some libraries combined in a function.The basic outline is a view to show the uploaded images and a view for the processed images when the user enter the url/view of the processed image it should show the processed images of a single image. how can i make that possible ? should i make 2 data models one for the uploaded and the other for the processed ? i made a function for defining a user path for the image so as the user can process the image multiple times how can i make a function to define a new name/path to the processed image ? I saw basic code on gearheart where it looks something like this: #forms.py class UploadFileForm(forms.Form): title = forms.CharField(max_length=50) file = forms.FileField() #views.py def handle_uploaded_file(f): with open('some/file/name.txt', 'wb+') as destination: for chunk in f.chunks(): destination.write(chunk) def upload_file(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): handle_uploaded_file(request.FILES['file']) return HttpResponseRedirect('/success/url/') else: form = UploadFileForm() return render(request, 'upload.html', {'form': form}) so it should look like this but how to save the processed data in a different field/model to be … -

Improve Django database performance by oriding or index?
I'm working on a project in which around 3 million records are saved in a MySQL database. The model is like: class Record(models.Model): rec_type = models.CharField(...) rec_value = models.FloatField(...) rec_prop1 = models.CharField(...) ...other fields... class Meta: ordering = ['rec_value'] A typical query contains a range of target rec_value, a specific rec_type， and sometimes, a specific rec_prop1. The query action is much more frequently used than the adding record action. My query function is written like this: def find_target(value_from,value_to,type=None,prop1=None): search_set = Record.objects.all() if type: #not None search_set = search_set.filter(rec_type=type) if search_set.count == 0: return [] if prop1: #not None search_set = search_set.filter(rec_prop1=type) if search_set.count == 0: return [] search_list = search_list.filter(rec_value__gte=value_from,rec_value__lte=value_to) result_list = [] for rec in search_list.values(...): #only get useful fields result_list.append(some_runtime_calculation_about_rec) return result_list The code works fine but takes around 7s for each query. No indexing is used currently. I want to improve query performance. I have searched the Internet for solutions and learned to use QuerySet.values() and database indexing. The problem is that rec_type field only has 3 possible values(eg. A, B, C), and the most of the records (around 70%) belong to one of them(eg. A). The rec_value field is filtered in every query so I made … -
