Why would autocommit in django 1.4 slow down unit tests?
Django 1.4 operates by default with the database-level autocommit setting off. I have recently tried turning this setting on and it has slowed down my test suite considerably. DATABASES['default']['OPTIONS'].update({'autocommit': True}) My understanding is that now every call to create, save etc. by default opens a transaction and issues a commit statement. Would the cost of all these additional transactions be enough to explain the slow-down of the unit tests? How does the django TestCase transaction behaviour come in to play with this (operating each test within a transaction and rolling back once completed)? Should we expect the performance reduction in the unit tests to be reflective of performance of the views in production? -
Why does Microsoft SQL Server respond with malformed packets to Django web server?
I have a web based Django application that communicates with a Microsoft SQL Server Database that is setup on a different server. Recently, the users of the app have complained that the app is responding very slow (30s to 2m delay on every request), so I ran some Wireshark tests to see where the delay comes from. I noticed that the Django app sends the requests to the DB in less that 1 sec, so the problem seems unrelated to the app itself. On the other hand, the DB responds with malformed TDS packets and it takes about 30s until it successfully sends the response. Unfortunately, the app is installed on a customer's server that had very sensitive data, so I was not able to get any exports of the Wireshark logs. If it's any help, the Django app is hosted a Windows Server VM and the database is hosted on a physical server. What I need to know is what could cause the malformed packets from the SQL Server response. Thanks! -
How can I pass a parameter to a Bootstrap modal?
While developing a website, I've encountered this problem: I've a list of panels movies, created using a for loop, and each one of them has a "Delete" button. Each delete button has an unique id (movie id in my database). I need to send that id to the backend, developed in Django, using AJAX. How can I achieve this? Here is my HTML code for creating the movie panel list: <ul> {% if film_list %} {% for film in film_list %} <li class="list-group-item"> <div class="row"> <div class="col-md-3 col-xs-3 col-sm-3 col-xl-3 name"> <img width="50" height="50" src= {{ film.poster }} alt= {{ film.title }}> <strong> {{ film.title }} </strong> </div> <div class="col-md-9 col-xs-9 col-sm-9 col-xl-9"> <div class= "col-md-4 col-xs-4 col-sm-4 col-xl-4"> <button id = "{{ film.id }}" class="btn boton-delete" data-toggle="modal" data-target=".modal-delete"> <span class=" glyphicon glyphicon-trash delete"></span> Borrar película </button> </div> </div> </div> </li> {% endfor %} {% endif %} </ul> And here is the HTML code of the modal: <div class="modal fade modal-delete" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true"> <div class="modal-dialog modal-md"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button> <h4 class="modal-title">¿Está seguro de que quiere borrar esta película?</h4> </div> <div class="modal-footer"> {% csrf_token %} <button type="submit" class="btn btn-success modal-btn-si">Si</button> <button type="submit" … -
Django database connection library issue
I faced an illogical issue. When I use connection created from cx_Oracle, It is working as assumed. But when I use Django DB connections, It is giving result but not as expected. import cx_Oracle from django.db import connections import pandas as pd dsn_tns = cx_Oracle.makedsn('10.253.1.201', '51621', 'DMSMTREC') cx_Oracle_conn = cx_Oracle.connect('MTRECDB', 'MTRECDB', dsn_tns) django_conn = connections["DB2"] # In django settings, I have a created "DB2" and passed the same parameters. query = ''' SELECT (T1.ACCEPTED- T2.CANCELLED) AS "NET" FROM ( SELECT ID, COUNT(1) AS ACCEPTED FROM ACCEPTED_TABLE GROUP BY ID ) T1 LEFT JOIN (SELECT ID, COUNT(1) AS CANCELLED FROM CANCELLED_TABLE GROUP BY ID) T2 ON T1.ID=T2.ID ''' df1 = pd.read_sql(query, cx_Oracle_conn) # Gives right result df2 = pd.read_sql(query, django_conn) # Gives only count of T1.ACCEPTED(T2.CANCELLED having 0 count) Questions: What is the reason for this? How a connection can effect the execution of query? Is it a bug of Django? Or Do I need to use django connections in other way? Versions: Django == 2.1.2 Python == 3.6.7 'ENGINE': 'django.db.backends.oracle' # As mentioned in django document in DB connections -
Django rest API formatting data
I am new in Django rest API. I create an API for my project where user can get data from the system via API.

Sorting records by calculated field computed in the model
So I need to ve able to sort the records by a calculated field which is calculated in the model side . So my model is something like: class User(models.Model): data = models.DateTimeField(null=True, blank=False,) average = None # Average avg field has a value # when get_deviation is being added in list_display def get_deviation(self): return abs(self.average- self.data) get_deviation.short_description = 'deviation' get_deviation.allow_tags = True And in my admin Model: class UserAdmin(admin.ModelAdmin): list_display = ('data') def changelist_view(self, request, extra_context=None): # other code #average value is calculated and seted in user model list_display = ('data','get_deviation') return super(UserAdmin, self).changelist_view(request, extra_context) So I need to be able to sort by the new field in the record list . any advice? -
Django Logging all the GET requests
I'm trying to put all the GET requests that appear in console into the database from django. For example: console log: [23/May/2019 13:58:44] "GET /testapp/ HTTP/1.1" 200 409 [23/May/2019 13:58:45] "GET /testapp/page2/ HTTP/1.1" 200 172 I'm trying to get the timestamp, page URL and user name from it and put in the database, so the entries looks something like this in the database: id user pageURL timeStamp 96 naeem /testapp/ 2019-05-23 09:37:12.640613 97 naeem /testapp/page2/ 2019-05-23 09:37:13.317271 This is the code I have written for the middleware: from TestApp.models import ActivityLog class AccessLogs(object): # One-time config def __init__(self, get_response): self.get_response = get_response def __call__(self, request): response = self.get_response(request) # Add the user and page info into DB try: ActivityLog(user=request.user, pageURL=request.path).save() except Exception as e: print(e) return response The problem is that it gives me the desired result, but it does not get the results if I click on a downloadable file, or an image. Like I have a static image on the website which is downloaded on click, like: <a href="{% static 'TestApp/media/cat.jpg' %}" download>Click here to open image</a> So if I click on that, it shows in the console that the image was downloaded, but it doesn't put that … -
How to select data from a queryset and group by counts for a specific date
When I query my database I get the same entry three times with three different counts. In the result list I would like to get just one entry showing the sum of these counts. What I would like to display is the total for a specific period. In my query I enter the dates (from - until), a metric_type, a data_type and a year of publication. For instance I on the website when I enter from 201903 until 201905 I retrieve three titles that have been accessed in this period as well as how many times they have been accessed. Title, [...], Counts Title A 3 Title A 5 Title A 3 What I would need is something like Title, [...], Total for that period Title A 11 In views.py I have the following code: q_report = Q() var0 = self.request.GET.get("period1", "") var1 = self.request.GET.get("period2", "") var2 = self.request.GET.get("metric_type", "") var3 = self.request.GET.get("data_type", "") var4 = self.request.GET.get("YOP", "") if var0: q_report = q_report & (Q(month__gte=var0) & Q(month__lte=var1) ) #q_report_count = q_report_count & (Count(month__gte=var0) & Count(month__lte=var1) ) if var2: q_report = q_report & (Q(metric_type=var2)) #q_report_count = q_report_count & (Q(metric_type=var2)) if var3: q_report = q_report & (Q(data_type=var3)) if var4: q_report = q_report … -
Django-polymorphic - how to set ordering?
I use django-polymorphic for multiple product types. class Product(PolymorphicModel): order = models.PositiveSmallIntegerField(default=999, verbose_name='Poradie') class WoodProduct(Product): .... class IronProduct(Product): .... class PlasticProduct(Product): .... I want to set default ordering (or explicitly specify when filtering QuerySet) based on 1. model type 2. order attribute The closest I got is to set ordering = ['polymorphic_ctype_id'] in the class Meta of Product model. So now I have grouped products by model type but I can't set, which type will be the first,second etc... How can I ensure that Product.objects.all() will return QuerySet with ordering - WoodProducts , PlasticProducts, IronProducts ? -

Too many URL get request sent to server for django ModalForm in jquery
I am trying to open a django modalForm. Since the specific URL to this modalForm is depending on a tablerow I calculate the URL on a mouseenter event and sent the url to the server on a click event. However, on the click event is sends multiple get requests to the server instead of one. $('.dt-edit').on('mouseenter', function(evt){ $this = $(this); adresid = parseInt($this.parents('tr')[0].cells[13].innerHTML); console.log("AdresID: " + adresid) modaltmpurl = "{% url 'adres-update-modal' 0 %}".replace(/0/, adresid) $('.dt-edit').modalForm({ formURL: modaltmpurl }); }); The adresid value behaves as expected. So if my make my mouse enter each .dt-edit once and click each element once, the console log shows: AdresID: 16 AdresID: 17 AdresID: 15 AdresID: 13 AdresID: 14 whereas my server shows: [23/May/2019 11:07:37] "GET /adres/16/updatemodal/ HTTP/1.1" 200 7033 [23/May/2019 11:07:41] "GET /adres/16/updatemodal/ HTTP/1.1" 200 7033 [23/May/2019 11:07:42] "GET /adres/17/updatemodal/ HTTP/1.1" 200 7011 [23/May/2019 11:07:45] "GET /adres/16/updatemodal/ HTTP/1.1" 200 7033 [23/May/2019 11:07:45] "GET /adres/17/updatemodal/ HTTP/1.1" 200 7011 [23/May/2019 11:07:46] "GET /adres/15/updatemodal/ HTTP/1.1" 200 6955 [23/May/2019 11:07:49] "GET /adres/17/updatemodal/ HTTP/1.1" 200 7011 [23/May/2019 11:07:49] "GET /adres/15/updatemodal/ HTTP/1.1" 200 6955 [23/May/2019 11:07:49] "GET /adres/16/updatemodal/ HTTP/1.1" 200 7033 [23/May/2019 11:07:50] "GET /adres/13/updatemodal/ HTTP/1.1" 200 6958 [23/May/2019 11:07:53] "GET /adres/17/updatemodal/ HTTP/1.1" 200 7011 [23/May/2019 11:07:53] "GET /adres/16/updatemodal/ … -

How can I pass one parameters visible in URL and one more not with Django?
I want to pass 2 arguments thought url. The first one is an ID that I want to see in URL. The second is a counter but, this time, i don't want to see it in URL. This arguments come from a function "insert_inventory" and are going to "insert_resort". I don't know how i can do that. I'm trying with kwargs but that's didn't work. I'm using Django 2.2 urls.py path('insert_resort/<int:id_inventory>/', view_resort.insert_resort, kwargs={'id_inventory': 'id_inventory', 'cpt': 'cpt'}, name='insert-resort'), A part of insert_inventory function def insert_inventory(request) #Some code here... kwargs_resort = { 'id_inventory': id_inventory, 'cpt': 1, } return HttpResponseRedirect( reverse( 'insert-resort', kwargs=kwargs_resort, ) ) If someone understands my question and can redirect me on a good practice or a solution, i'll be thankful. -
How to handle reading, extracting & saving extremely large csv or excel data having an Angular client and a Django server
I've implemented a back-end functionality where one can upload a CSV or excel an file and then the server(Django API) will read and save all the data into the database but I feel like it's not the best approach and would like to get advise about this. I don't see the reason why the server is required to read and validate the CSV file while it's possible for the client(Angular app) to do that job. The client can read validate the file and the sends the data to the server. Then the server will do the rest of the job to save the data into the database. But I've come to think of it, suppose the file contains a million entries this means the server endpoint will be adding a million items. This will cause performance issues. What is the best approach to handle this? -
Cannot properly configure Django to run tests with nosetests

You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. I don't know what more to do with this.

Model delete() and deserialized_object.save() calls don't work if called consecutively
I am trying to import json to my django webapp and its almost working fine except one problem. When I delete the objects 1-2 lines before calling deserialized_object.save() it works fine but if I call delete() and then save() consecutively it does not work properly. THIS WORKS FINE def builder_import(request, pk): if request.method == 'POST': file = request.FILES['myfile'] data = file.read() LogrepoIQLMap.objects.filter(logrepo__iql_index_builder__pk=pk).delete() for deserialized_object in serializers.deserialize("json", data): if object_should_be_saved(deserialized_object): deserialized_object.save() return redirect(reverse_lazy('indexbuilderapp:builder-update', kwargs={'pk': pk})) THIS DOES NOT WORK def builder_import(request, pk): if request.method == 'POST': file = request.FILES['myfile'] data = file.read() for deserialized_object in serializers.deserialize("json", data): if object_should_be_saved(deserialized_object): LogrepoIQLMap.objects.filter(logrepo__iql_index_builder__pk=pk).delete() deserialized_object.save() return redirect(reverse_lazy('indexbuilderapp:builder-update', kwargs={'pk': pk})) The first snippet works fine but the second snippet does not. In First case it deletes all entries and then uploads everything correctly in DB. But in second case it deletes and then uploads only one entry for some strange reason. May be it is some Synchronization issue but I thought django DB operations and well synchronized. What could be wrong?
