Need to build a Django queryset based on more models
So what I say might seem complicated, but I think the answer is easy. I just can't figure it out. I have a form for a Lecture model, which a logged in teacher can use to post a lecture for his specific courses only. Thing is that in my database I have a TeacherData model which contains a teacher_ID field used for verification, so a teacher cannot create his account on the other Teacher model, if teacher_ID entered doesn't match. But when a course is created in database, the teacher used is the one from TeacherData. So to create my query I have to filter the courses based on TeacherData and then using teacher_ID, to link to Teacher model. I just don't know how to build this queryset but I replicated the wanted behaviour in the template: {% if user.is_authenticated and user.is_teacher %} <ul> {% for data in teacher_data %} {% if data.teacher_ID == user.teacher.teacher_ID %} {% for course in courses %} {% if course.teacher1 == data or course.teacher2 == data %} <li> <a href="{% url 'courses:courses' slug=course.slug %}">{{ course.name }}</a> </li> {% endif %} {% endfor %} {% endif %} {% endfor %} </ul> {% endif %} class Teacher(models.Model): … -
No connection with dockerized nginx gunicorn

How to multiply a floating point number and a decimal in Django?
I am using django 2.0 and Python 3.6.4 I have a field in my model called total which is a decimal field. total = models.DecimalField(default=0.00, max_digits=100, decimal_places=2) I want to calculate the value after multiplying it with 1.15 in a function. def calculate_tax(self): tax_total = instance.total * Decimal(1.15) It's giving me errors: unsupported operand type(s) for *: 'float' and 'Decimal' -
How to update only the queried objects in django
I have a table ActivityLog to which new data is added in every second. I am querying this table every 5 seconds using an Api in the following way. logs = ActivityLog.objects.prefetch_related('activity').filter(login=login_obj,read_status=0) Now let's say when I queried this table at time 13:20:05 I've got 5 objects in logs and after my querying 5 more rows were added to the table at 13:20:06. When I try to update only the queried logsdataset using logs.update(read_status=1) it also updates the newly added data in the table. That is instead of updating 5 objects it updates 10 objects. How can I update only the 5 objects that I've queried without looping through it. -

Django ReST Framework - Extended User model not accepting "null=true"
I have checked a lot of similar questions but no one has encountered such an issue in django shell : I am using Django 2 and DRF 3.7.7 with Python 3.6 and PostgreSQL 10.1 on Ubuntu 16.04 LTS. I am writing a booking application and trying to extend Django user model with OneToOneField (Using the guide here without using Signals' methods). I have had some experiences coding in Python 2.7 for some time, but this is my first experience with Django.

Recommendation for full text search option for Django web
I have a website with monthly pageviews around half a million. I am planning to implement a search functionality on site. I am stuck with different options available. I want to go with a package which is easy to use and can search from multiple models (basically its a CMS website with multiple Models.) What you think of django-watson? What about django inbuilt postgres full text search? Does it support searching from multiple models and ranking contents from multiple models? -

Django, compare list of dates in form field to check if exist for user
I have this problem, I have a system of reservations that needs to limit reservations made in Friday, for the user, to be only one per month, Friday is the last day the users can make a reservation. I made a range of dates that correspond to Friday in the month using a library called pandas, this gets me a list of dates. import calendar import pandas as pd from datetime import date fecha = date.today() _, dias = calendar.monthrange(fecha.year, fecha.month) primer_dia_mes = date(fecha.year, fecha.month, 1) ultimo_dia_mes = date(fecha.year, fecha.month, dias) dias_viernes = pd.date_range(start=primer_dia_mes, end=ultimo_dia_mes, freq='W-FRI').strftime('%Y-%m-%d').tolist() Ok, now Im trying to make a way to validate this list of dates with the date that the user put in the date field in the form. def post(self, request): form = ReservacionForm(request.POST) reservaciones = Reservaciones.objects.exclude(usuario=request.user) reservaciones_usuario = Reservaciones.objects.filter(usuario=request.user) reservaciones_fechas = Reservaciones.objects.filter(usuario=request.user, envio=timezone.localdate()).count() fecha = date.today() _, dias = calendar.monthrange(fecha.year, fecha.month) primer_dia_mes = date(fecha.year, fecha.month, 1) ultimo_dia_mes = date(fecha.year, fecha.month, dias) dias_viernes = pd.date_range(start=primer_dia_mes, end=ultimo_dia_mes, freq='W-FRI').strftime('%Y-%m-%d').tolist() for f, u in zip(dias_viernes, reservaciones_usuario): if str(u.fechas) == str(f): fin_semana_mes = True else: fin_semana_mes = False if form.is_valid() and fin_semana_mes == False: if reservaciones_fechas < MAX_RESERVATION_POST: nucleo = form.cleaned_data['nucleo'] cabaña = form.cleaned_data['cabaña'] fechas = form.cleaned_data['fechas'] post … -
Explanation of Django Table Relations and How they are Being Called
I'm fairly new to Django and am currently trying to go through and modify a preexisting website. I'm trying to understand the syntax involved with creating a chart based on certain parameters. Currently the site takes account types as an argument and spits out a plot of account values vs. years. As shown in the first picture: Picture of Plot The part of the code I'm confused about is here: tag_ids = [56, 123, 15, 21, 82] if categories_1: tag_ids = categories_1.split(',') tags = [] funding_announced_min = minyear+'-01-01' funding_announced_max = maxyear+'-12-31' business_list = [] for d in tag_ids: tag1 = Tag_objs.objects.get(pk=int(d)) tags.append(tag1) business_1 = tag1.buisiness.filter( company__founded_date__gte=funding_announced_min, company__founded_date__lte=funding_announced_max, entity_type=0, ) business_list.append(business1) tag is a table of account types, and my confusion comes from the business_1 = tag1.business.filter section. What exactly is this doing? I have a model called biz that looks like this: class biz(Ent): founded_date = models.DateField(blank=True, null=True) employee_amount = models.IntegerField('Number of Employees',blank=True, null=True) employee_amount_range = models.CharField(max_length=64, blank=True, null=True) biz_status = models.CharField(choices=BIZ_STATUS_CHOICES, max_length=32, default='operating', blank=True, null=True) zipcode = models.CharField(max_length=64, blank=True, null=True) address = models.CharField(max_length=255, blank=True, null=True) funding_rounds = models.IntegerField(default=0, blank=True, null=True) funding_total_usd = models.BigIntegerField(default=0, blank=True, null=True) first_funding_on = models.DateField(blank=True, null=True) last_funding_on = models.DateField(blank=True, null=True) closed_on = models.DateField(blank=True, null=True) employee_count_min = … -

How to fix Python MySQL connection issue, Python 2.7, MySQL 5.7
I'm working with an Ubuntu (Linode) 16.04 LTS / nginx / uwsgi / Python-2.7 / Django / MySQL 5.7 application. A little more than a month ago the box was dist upgraded from 14.04 LTS, and at that time or soon after that MySQL was upgraded from 5.5 to 5.7. We had to recreate the Python virtual environment, and then things worked fine. Up until today when Linode Fremont experienced issues, and the box was restarted. Since that restart we are experiencing undeterministic MySQL restarts. One suspicion is a possible file system corruption in case the restart was preceded by a "pull the plug out" type power down (the report contains the keyword power failure). I restarted again the box forcing fsck, and I still won't rule that out completely, but I rather seek for software issues. The MySQL logs don't contain any suspicious. The uwsgi logs however show: ...The work of process 27651 is done. Seeya! worker 1 killed successfully (pid: 27651) Respawned uWSGI worker 1 (new pid: 27686) Fri Feb 23 18:33:38 2018 - SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) !!!

How can I combine CreateView and Bootstrap modal inside current url
Let me crearify the question: I want to create a post through a Bootstrap modal which is hosted in my blog home where there are already a ListView of all posts rendered.

Uploading Files in Django - How to avoid the increase of files in the upload directory
I've been working on uploading a file on Django. I have the following code to run things. def handle_uploaded_file(file, filename): if not os.path.exists('upload/'): os.mkdir('upload/') with open('upload/' + filename, 'wb+') as destination: for chunk in file.chunks(): destination.write(chunk) def upload_csv(request): # Get the context from the request. context = RequestContext(request) if request.is_ajax(): if "POST" == request.method: csv_file = request.FILES['file'] my_df = pd.read_csv(csv_file, header=0) handle_uploaded_file(csv_file, str(csv_file)) ............................. ............................. As you can see above, I have been uploading files to the upload directory. However, my concern is that this type of method might not be that much efficient because each file is kept and stored in that folder. What if hundreds or thousands of files are uploaded each week? See this: What would be the other way to efficiently and effectively upload files? -

How to modify Django's DateTimeInput widget to select times at 15-minute increments instead of 30?
I have a form with a default DateTimeField which includes a drop-down menu for the time of day in 30-minute increments: I'd like to change this so that times are selectable at 15-minute increments instead of 30-minute ones. Looking into Django's source code (https://github.com/django/django/blob/master/django/forms/widgets.py) for the DateTimeInput widget (which is the default widget for DateTimeField), it is not immediately clear to me how I would customize it to adjust the interval spacing: class DateTimeInput(DateTimeBaseInput): format_key = 'DATETIME_INPUT_FORMATS' template_name = 'django/forms/widgets/datetime.html' Any ideas how I might go about this customization?

Edit base.css file from S3 Bucket
I'm using AWS S3 to serve my static files - however I've just found out you can't edit them directly from S3, which kind of makes it pointless as I will be continuously changing things on my website. So - is the conventional way to make the changes then re-upload the file? Or do most developers store their base.css file in their repository so it's easier to change? Because I'm using Django for my project so there is only supposed to be one static path (for me that's my S3 bucket) - or is there another content delivery network where I can directly edit the contents of the file on the go which would be better? -
Django Inline ManyToOne with Foreign key through third model
I am currently implementing a website some external packages. One of these (https://github.com/dj-stripe/dj-stripe) adds Customer and Cards to the Models. The Foreign keys are User <- Customer <- Card Customer has Customer.subscriber which is a foreign key to User and Card has Card.customer wich is a foreign key to Customer. I would like to Inline the Card to the UserAdmin, but the throughkeyword is only working for Many-To-Many Foreign Keys. I tried to do so by manipulating the get_queryset of the TabularInline Subclass, but this leads to check errors, because the desired fields are not part of the provided Model. class CustomerInline(admin.TabularInline): extra = 0 model = Customer readonly_fields = ('customer_id', 'stripe_id', 'last4') def get_queryset(self, request): customer_set = super(CustomerInline, self).get_queryset(request) qs = Card.objects.none() for customer in customer_set: qs = Card.objects.filter(customer=customer) return qs More general: How to inline a model admin with indirect foreign key connection?
