Django - annotate on multiple fields and load relevant objects
Let's say I have the following models class Author(models.Model): name = models.CharField(max_length=25) ... class Publisher(models.Model): name = models.CharField(max_length=25) ... class Book(models.Model): author = models.ForeignKey(Author) publisher = models.ForeignKey(Publisher) ... For some reason, I want to query books and group results by the author and publisher, so: books = Book.objects.values('author', 'publisher').annotate('sth'=Avg('sth_else')) with the results looking like: <BookQuerySet [{'author': 2, 'publisher': 1, 'sth': 1.0}]> Is it possible to load the whole Author and Publisher objects and not just their related ids? -

how to display count and sum on your website? postgresql, django
I am making a dashboard with django and postgresql, but I am having trouble with the sum and count select functions from sql. home.html <h5 class="card-title">{{total_monney}}</h5> views.py def home(request): d = Dashboard() total_monney = d.getTotalMonney() return render(request, 'home.html', {'total_monney': total_monney}) app.py class Dashboard: def getTotalMonney(self): sql = "SELECT SUM(product_price) FROM products" sqldata = () c = cursor('dashboard', sql, sqldata) result = c.connect() return result the result is that it displays this on the page, how do i only get the "33200"? [RealDictRow([('sum', 33200)])] Everthing works when i dont use the sum and count and just the select, so i dont know if i have todo something diffrent when i use these functions. I get the same result with count too -
Django pagination resets
I am building an application that lists certain records from a database. The database is quite large and I am building a pagination to show a specific number of rows. Currently I have set a default value for the paginate_by. Here is the class that I am using. class HomePageView(ListView): model = Syslog template_name = 'home.html' context_object_name = 'all_logs'; paginate_by = 10 def get_paginate_by(self, queryset): return self.request.GET.get("paginate_by", self.paginate_by) I have implemented and a feature that allows clients to change the pagination levels like so: <form action="" method="get"> <select name="paginate_by" onchange='this.form.submit()'> <option>1</option> <option>2</option> <option>3</option> <option>4</option> </select> </form> When the home page is loaded with the default value the number of pages show correctly. When a user submit another paginate_by value the number of pages change accordingly. The problem is that when the pagination parameter is changed and a user click on let's say 2nd page the paginate_by resets to the default. Regards, Jordan -
How can I convert the value of a DurationField to its number of microseconds in a QuerySet?
Suppose I have two models: Computer and DailyUsage. DailyUsage has a DurationField named usage_duration. On a QuerySet of Computers, I want to annotate the average daily usage in minutes. Each additional minute the computer has been used on average per day, the computer's "importance" increases. I have seen examples* of people using ExpressionWrapper to convert a DurationField to its BigIntegerField representation, but attempting this: average_in_duration_annotated = Computer.objects.annotate( avg=Avg("daily_usages__usage_duration", filter=Q(daily_usages__date__gte=one_month_ago)) ) average_in_minutes_annotated = average_annotated.annotate( avg_in_minutes=ExpressionWrapper(F("avg"), output_field=BigIntegerField()) / Value(10e6 * 60) ) ... results in: {TypeError}int() argument must be a string, a bytes-like object or a number, not 'datetime.timedelta' when the QuerySet is evaluated. Another example that fails the same way: Computer.objects.annotate( total_usage_minutes_microseconds=Sum("daily_usages__usage_duration", output_field=BigIntegerField()) ) How can I convert the value of a DurationField to its number of microseconds in a QuerySet? * Aggregate in django with duration field -
How to match time range if to_date can be Null in Django?
I have two date, let's say from_date and to_date, and I have column with prices for that range. It looks like this in my models: class PriceList(models.Model): from_date = models.DateField(verbose_name="Start date") to_date = models.DateField(verbose_name="End_date", null=True) product = models.ForeignKey(Models, on_delete=models.CASCADE) price = models.DecimalField(verbose_name="EUR/h", max_digits=10, decimal_places=5) I know how to get record for the correct product in a period if a to_date is available, but I am not sure how to fetch it if it is Null, that means from from_date to forever (until changed). And, obviously, would like to have query that will work in both scenarios - if ther is a to_date and if it Null. -

Fullcalendar cannot display event after event has been created (Django and Javascript)
currently I cannot display event after event has been created. In fact, I cannot display event at all from database. Previously, I made something like this and it worked. views.py def calendar(request): all_events = Events.objects.all() context = { "events":all_events, } return render(request,'fullcalendar/calendar.html',context) calendar.html events: [ {% for event in events %} { title: "{{ event.title}}", start: '{{ event.start|date:"Y-m-d" }}', end: '{{ event.end|date:"Y-m-d" }}', id: '{{ event.id }}', }, {% endfor %} ], But right now, I wanted to insert the part which is in the calendar.html to script.js and I tried to use EventSources but I failed to make events display on fullcalendar. Does anyone know how to convert the part which is in calendar.html to script.js? The reason why I decided to use script.js is because if I put everything in HTML, it will get really long. Currently, my EventSources of script.js looks like this. script.js eventSources:[{ url: '/fullcalendar/calendar', method: 'GET', success: function(){ alert("GOT IT!!"); }, failure: function(){ alert("PROBLEM!!!"); }, } ], it seems I have done nothing but trust me I have searched all over the place and tried so many things but I still fail to make the event display on the fullcalendar.

guys is it possible to check continuously if .sh (any script) file is running or not. with portal that monitor .sh services for example sample test backup.sh service running every 15 minute that take backup in cronjob. mkdir "/dev/my backup directory" mv /var/log/*2007* "/dev/my backup directory/" sed -i '/:[0-9][0-5]:/ {d}' "/dev/my backup directory/*" this is simple test script but is it possible that we can check throw portal that show if service is running or not that send alert if it is stop or started in web-application if it is possible in python or another language than where i can find useful information. -
Django: ValueError: Missing staticfiles manifest entry for 'jquery.twbsPaginationAlt.min.js'
Before marking as duplicate, note that I've checked all the similar questions that have been asked and it has not fixed my problem. I've deployed my Django App on Heroku in in one template where I reference a min.js file, it throws this error in question. My basic directory structure is this: myapp mysite dictionary static jquery.twbsPaginationAlt.min.js staticfiles settings.py: STATIC_URL = '/static/' # STATIC_ROOT = [os.path.join(BASE_DIR, 'staticfiles'), os.path.join(BASE_DIR, 'static/fonts')] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') if DEBUG: STATICFILES_DIRS = [os.path.join(BASE_DIR, 'mysite/static'), os.path.join(BASE_DIR, 'static/')] import django_heroku # handles staticfiles, database url, and secret key, can be overwritten as needed django_heroku.settings(locals(), secret_key=False, logging=False) So originally if STATICFILES_DIRS had any value, I would get an error of FileNotFoundError: [Errno 2] No such file or directory: '/tmp/build_6f3eb879/mysite/static' when running collectstatic on heroku. However, if it is not set, than the fonts I have in my dev environment do not load in properly (I also have fonts inside the base level static folder). This is how I reference the js file in my problem template, it works fine on dev: <script src='{% static 'jquery.twbsPaginationAlt.min.js' %}'></script> For convenience, here is what django-heroku does in terms of staticfiles: logger.info('Applying Heroku Staticfiles configuration to Django settings.') config['STATIC_ROOT'] = os.path.join(config['BASE_DIR'], 'staticfiles') … -

How to set the maximum image size to upload image in django-ckeditor?
I am using django-ckeditor for my project to upload image along with text content. I used body = RichTextUploadingField(blank=True, null=True) in model. Now I want to restrict the user to upload large size images in content or larger than predefined maximum height/width. I want the uploaded images in content of particular height/weight and size like less then 1mb. How can I predefine maximum image height and width as well as maximum image size limit? Is there any way to define it from django-ckeditor configuration? Or How to resize the uploaded images from content at backend after user submitted the form?

Optimize Serializer Performance in Django Rest Framework
I'm developing a web app using Django and Django Rest Framework and struggling with slow API responses which appear to be based on fetching data from related tables.

I am not experiencing this issue when I am manually logging out and logging in. Please help if someone else is also experiencing the same issue. Thanks in advance. -
What is the best way to implement a REST API based payment gateway for a Django web app
Should i make the payment requests from views.py or from them templates using javascript. Currently i am sending http requests from views.py to the REST API and the problem is how do i send the product price to the template and when the user confirms payment, how do i fetch the amount to be paid. The rest of the payment details like credit card number i collect from a checkout form.
