URLConnection hits server twice when downloading file?
After reading HttpURLConnection request being hit twice to the server for downloading file it was very similar and helped, but I still see my server gets two requests for a single download. This is my AsyncTask that I use to download a file from a Django web server. @Override protected String doInBackground(String... sUrl) { String path = "/sdcard/YourApp.apk"; try { URL url = new URL(sUrl[0]); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.addRequestProperty("Authorization", "Token " + authToken); urlConnection.connect(); int fileLength = urlConnection.getContentLength(); // download the file InputStream input = new BufferedInputStream(urlConnection.getInputStream());//url.openStream()); OutputStream output = new FileOutputStream(path); byte data[] = new byte[1024]; long total = 0; int count; while ((count = input.read(data)) != -1) { total += count; //publishProgress((int) (total * 100 / fileLength)); output.write(data, 0, count); } output.flush(); output.close(); input.close(); urlConnection.disconnect(); } catch (Exception e) { Log.e("SVC0", e.getMessage()); } return path; } Then I look at the Django logs and I can see that two requests are present: [09/Oct/2019 02:30:29] "GET /update HTTP/1.1" 301 0 [09/Oct/2019 02:30:35] "GET /update/ HTTP/1.1" 200 19451876 I have tried commenting out many parts but I just can't figure out why it's causing the 301 error. Any help tracking this 'bug' down would be very appreciated. -
How to send dictionary data with redirect function in Django
I'm trying to send a dictionary by the redirect method. But not getting it in the redirected template. I tried to pass the dictionary like it used to pass in the render function but I don't think I am doing this in the right way. I also tried HttpResponseRedirect but that doesn't work too. views.py def index(request): if request.method == "POST": url = request.POST.get('url', '') r = requests.get(url) soup = BeautifulSoup(r.content, features="lxml") p_name = soup.find_all("h2",attrs={"class": "a-size-mini"}) p_price = soup.find_all("span",attrs={"class": "a-price-whole"}) p_image = soup.findAll('img', {'class':'s-image','src':re.compile('.jpg')}) response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename="product_file.csv"' for name,price,image in zip(p_name,p_price,p_image): writer = csv.writer(response) row = writer.writerow([image['src'],name.text, price.text,]) name_data = [data.text for data in p_name] price_data = [data.text for data in p_price] image_data = [data['src'] for data in p_image] dec = {'name':name_data, 'price':price_data, 'image':image_data, 'url':url} return redirect('data', dec) return render(request, 'index.html') -
Noob Django question: When do I make an app vs coding something for the whole website?
I want to implement things like user logins for the entire website and not within a specific app. Can someone point me in the right direction/some reference I can look up? I've looked at tutorials for the login, and they all refer to building logins within an app, not the main website. Should I build a "Welcome" or "Registration" app, and then import it into every other app? -
API response time is too slow using DRF
Activity is tourist information and tag (Preference) is tag information (such as Instagram hash tag). Function of Activity ListPreference api: For every activity, check that each activity contains tags from the request list. Only the activities that contain the tags are serialized. But it's too slow. It takes about 1 minute. The api, which returns all activities, only takes 2 seconds. What's the problem? class ActivityListByPreference(APIView): permission_classes = (permissions.AllowAny,) def get(self, request): request_tag = [6, 7, 8] activity_list = [] activity_items = Activity.objects.filter() activity_nums=activity_items.values_list('num', flat=True) b=1 for activity_num in activity_nums: print(activity_num) activity_preference_items = Activity_Preference.objects.filter(activity_num_id=activity_num) activity_tag = [] preference_nums= activity_preference_items.values_list('preference_num_id',flat=True) activity_tag=list(preference_nums) intersection = set([]) intersection = set(request_tag).intersection(set(activity_tag)) inter_list = list(intersection) inter_list.sort() if (request_tag == inter_list): print('ν¬ν¨ν©λλ€.') activity_list.append(activity_num) activity_preference_items = Activity_Preference.objects.all() for activity_preference_item in activity_preference_items: activity_tag.append(activity_preference_item.preference_num_id) print('λ') data = Activity.objects.filter(pk__in=activity_list) serializer = ActivitySerializer(data, many=True) print(data) return Response({"ActivityListByPreference" : serializer.data}) -

How to execute custom SQL query when deleting a model item in Django?
I want to execute an SQL query, when an item gets deleted in the admin interface. In models.py I do this: from django.db import connection class LList(models.Model): item = models.ForeignKey(Item, models.DO_NOTHING) def delete(self, *args, **kwargs): cursor = connection.cursor() cursor.execute('DELETE FROM some_table where item = %d', [self.item.id]) When I turn debugging on I see all the queries executed. It seems the DELETE FROM query is not executed, I only see (0.000) DELETE FROM `llist` WHERE `llist`.`id` IN (27); args=(27,) Why is the other DELETE FROM query not executed? How can I fix that? -

Rename Django User fields
I'm using the default Django User class and authentication for a simple user LogIn. This User model has two important fields: "username" and "password". I want them to be "user" instead of "username", and "pass" instead of "password". I know I can make a RenameField, but that will only change the column name in the database, it won't change how Django asks for the username and password in the body of the POST request. I need to change the keys in the JSON given in the request. from: { "username": "user123", "password": "pass123" } to: { "user": "user123", "pass": "pass123" } And I think I can create a file called serializer and do something there but I'm not sure how, and I didn't found anything in the documentation.

Django + django-rest-framework-simplejwt protect view
I just installed django-rest-framework-simplejwt in a Django project and if I send an invalid Authentication Bearer <<token>> header, it blocks my request with 401 code. Which is the expected behavior. The problem is that if I remove the Authentication header, I can access my view, so it's unprotected. How can I protect the view to return 401 if there is no Authentication header? Here's the view code: class AuthTestView(views.APIView): http_method_names = ['get'] def get(self, request): response_data = { 'result': 'Restricted access test ok.', } return Response(data=response_data, status=status.HTTP_200_OK) -

Extracting array with indices from GET parameters in Django
My Django project has a page that features a table powered by DataTables. In this case, the table uses server-side processing using a Django view and the GET http method. The Django view unpacks the query string into a QueryDict object, and my task is to unpack the DataTables parameters for each column of the table from this QueryDict. Note that I must use GET, not POST, because I want to use the POST method for other things that actually change data on the server. DataTables submits data for each column in the table relating to search strings and sorting for each column. This data is submitted as per their documentation here; the main point is that columnar params are sent up in the query string like this: ...&column[5][search][value]=searchme&column[6][search][value]=more&... I would like this to be unpacked in such a way that the resultant data structure looks something like this: column = [ { 'search': { 'value': 'searchme' } }, ... ] ...With the elements of the array submitted in the query string in the order specified by their indices. Is there a standard way of accomplishing this with Django's QueryDict? -

HTML : <form id="modify" class="form-horizontal" action="{% url 'modify' customer.customerid %}" method="POST"> {% csrf_token %} <fieldset class="scheduler-border"> <legend class="scheduler-border">{{ customer.customername }}</legend> <div class="form-group"> <span class="col-md-1 col-md-offset-2 text-center"><i class="fa fa-building bigicon"></i><label for="txtCustomerName">Customer Name</label></span> <div class="col-md-11"> <input type="text" name="txtCustomerName" id ="txtCustomerName" class="form-control" placeholder="Customer Name" value="{{ customer.customername }}" disabled="True"> </div> </div> <div class="form-group"> <span class="col-md-1 col-md-offset-2 text-center"><i class="fa fa-building bigicon"></i><label for="txtCustShortName">Customer Short Name</label></span> <div class="col-md-11"> <input type="text" name="txtCustShortName" id="txtCustShortName" class="form-control" placeholder="Customer Short Name" value="{{ customer.customershortname }}" disabled="True"> </div> </div> <div class="form-row"> <div class="form-group col-md-5 col-md-offset-2 text-left"> <span class="col-md-1"><i class="fa fa-user bigicon"></i><label for="txtContactFirstName">Contact Person First Name</label></span> <div class="col-md-12"> <input type="text" name="txtContactFirstName" id="txtContactFirstName" placeholder="Contact Person First Name" class="form-control" value="{{ contact.firstname }}" disabled="True"> </div> </div> <div class="form-group col-md-1 text-left"> </div> <div class="form-group col-md-5 col-md-offset-2 text-left"> <span class="col-md-1"><i class="fa fa-user bigicon"></i><label for="txtContactLastName">Contact Person Last Name</label></span> <div class="col-md-12"> <input type="text" name="txtContactLastName" id="txtContactLastName" placeholder="Contact Person Last Name" class="form-control" value="{{ contact.lastname }}" disabled="True"> </div> β¦ -
Taking a form response, making an api call then displaying the api call in Django
I'm trying to have a Django form capture data from a user's input, take the input to make an API call to Aylien API and display the raw json result on the same page. I'm able to take the form input and successfully make an API call & get the JSON to print on the console, but am having a hard time displaying the call's result on the page.
