Use storages.backends.s3boto.S3BotoStorage to add tags to an s3 object
My question is around tagging s3 objects using S3BotoStorage. Through boto3 you can add tags to an s3 object before uploading it to an s3 bucket. this it the documentation for tagging s3 objects I was wondering if there is a way to add tags to an s3 object if the method of uploading is storages.backends.s3boto.S3BotoStorage. Thanks! -
Django: ImportError: cannot import name 'GeoIP2'
I am trying to set up geoip2 for GeoDjango as per the instructions. For some reason the wrapper isn't importing the function. It worked before I downloaded the databases and pointed to them in my settings, but for some reason now I can't load GeoIP2 (even when I comment out the line in settings.py). How should I troubleshoot this? Python 3.6.3 (v3.6.3:2c5fed8, Oct 3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.

Exception Type: MissingSchema / beautifulsoup
I'm exploring beautifulsoup en django and it worked fine until I added a variable as url (from a model textfield with URLValidator) I added an 'https://"+ before the model_url, but this gave also an error. what could be the problem? I googled a lot, but nothing worked.. hopefully it's not a double question.. thanks in advance!

Want to resolve a dictionary whose key is a field in a model
I have {% for competency in domain.competency_set.all %} <td> {{competency.id}} {{scoredict.8}} {% with cid=competency.id %} {{ scoredict.cid }} {% endwith %} </td> so scoredict.8 displays a value but when competency.id is 8, scoredict.cid comes up empty. What am I doing wrong? What's the workaround? I can see why scoredict.competency.id doesn't work, but I don't see how to change the order of evaluation. If I could force order of evaluation with parentheses I'd want something like scoredict.(competency.id) -
Django throws Operational Error with substituted Auth Model
apologies in advance if this is a duplicate question. To the best of my searches, I was not able to find this question. Using Django 2.0, I substituted the built-in django.contrib.auth with my own Users model, extending it with AbstractUser. The Users model is dependent on an existing table in MySQL, which is configured to work with Django. Django does not detect any issues when performing a check; however, I receive the following error: OperationalError at / (1054, "Unknown column 'users.last_login' in 'field list'") I added the column into the table thinking it would be a useful field to have, but was apprehensive because I figured I'd get another error for another missing field. Lo and behold: OperationalError at / (1054, "Unknown column 'users.is_superuser' in 'field list'") The point of substituting the user model is so I can ditch unimportant fields, such as "username". Do I just need to add each column to the table until I get all the auth fields in the table, or am I doing something fundamentally wrong? TL;DR: How do I create a custom authentication method for Django using an existing table? -
Django NoReverseMatch when redirecting to view

how to correctly assign the through attribute in django?
I was just looking the documentation to be able to change the intermediate table: https://docs.djangoproject.com/en/2.0/topics/db/models/#extra-fields-on-many-to-many-relationships but when I implement it, I get into trouble. I am developing an app where students can evaluate their teachers, my models are: class Item(models.Model): name = models.TextField() def __str__(self): return self.name class Category(models.Model): name = models.CharField(max_length=50,null=True) items = models.ManyToManyField(Item, related_name='categories') def __str__(self): return self.name class Professor(models.Model): name = models.CharField(max_length=50,null=True) categories = models.ManyToManyField(Category, related_name='professors') def __str__(self): return self.name class Student(models.Model): name = models.CharField(max_length=50,null=True) professors = models.ManyToManyField(Professor, related_name='students') def __str__(self): return self.name each student has Professor, these Professor in turn have associated categories of questions, and each category of questions has associated questions. what I want is to modify the intermediate table student_professor to add a field in which when the student evaluates a teacher, this is recorded in the database. I tried it with: class Professor(models.Model): name = models.CharField(max_length=50,null=True) categories = models.ManyToManyField(Category, related_name='professors') def __str__(self): return self.name class Student(models.Model): name = models.CharField(max_length=50,null=True) professors = models.ManyToManyField(Professor, related_name='students',through='Studentprofesor' ) def __str__(self): return self.name class Studentprofesor(models.Model): student = models.ForeignKey(Student, on_delete=models.CASCADE) professor = models.ForeignKey(Professor, on_delete=models.CASCADE) tested = models.BooleanField(default=False) the migration works without problems, and in the database I get the intermediate table student_professor with the fields I assigned in … -
Annotate Django queryset with previous Sunday based on row's date field
I have a table with a set of Orders that my customers made (purchased, to say so). The customers can choose the delivery date, and that is stored in each Order in a field called Order.delivery_date. I would like to annotate a queryset that fetches Orders with the previous Sunday for that date class Order(BaseModel): customer = ForeignKey(Customer, on_delete=CASCADE, related_name='orders') delivery_date = DateField(null=True, blank=True) I thought "Oh! I know! I'll get the date index in the week and I'll subtract a datetime.timedelta with the number of days of that week index, and I'll use that to get the Sunday (like Python's .weekday() function)": from server.models import * import datetime from django.db.models import F, DateField, ExpressionWrapper from django.db.models.functions import ExtractWeekDay Order.objects.filter( delivery_date__isnull=False ).annotate( sunday=ExpressionWrapper( F('delivery_date') - datetime.timedelta(days=ExtractWeekDay(F('delivery_date')) + 1), output_field=DateField() ) ).last().sunday But if I do that, I get a TypeError: unsupported type for timedelta days component: CombinedExpression when trying to "construct: the timedelta expression.

How can I stop a django server programatically
I want to perform some checks across a few environments being pointed to on startup of my django server to ensure consistency of the different environment configrations. For example, that they are all in dev configuration, or all in prod configuration. If this is not the case I would like to shut down the server. My question is what is the best way to shut down the server and report the issue? At the moment my plan is to raise a RuntimeError with the appropriate exception message. But I was wondering if there is any problem with this approach, or if there is a more suitable approach which I can not find. Researching the issue has unfortunately not yielded sufficient information. -

Choose which way to calculate the PV and UV in Django?
I'm building a news website using Django and hope this website can handle millions of traffic.Now I'm coding a function that displays 48 hours most viewed articles to readers,so I need calculate the PV. I have searched for a while and asked some people.I know I have some options: 1.using simply click_num=click_num+1,but I know this is the worst way. 2.A better way is using Celery to code a distributed task,but I don't know how to exactly do it. 3.I heard Redis also can used to calculate PV and UV but,have no idea how to do it and not sure the it can satisfy my needs. 4.Another good way is to use google analysis,but I also have no idea how to do it and not sure the it can satisfy my needs. 5.The last way ,I think the easiest way is to use JavaScript, but I'm not sure whether it can satisfy my needs. Any friend can give me some advice? Thank you so much! -

Create an instance of postgre with a "COLLATE" pt_BR (Kubernetes/GCloud)
Good afternoon sirs. I'm having a little difficulty. I have a system created in pytho and django. Previously I used sqlit3 to store the data and recently changed the database to postgre. The "COLLATE" that we use in Brazil is pt_BR, however, when we start an instance in kubernetes do gcloud, it automatically gets en_US. This is causing conflict in my system, because we use characters of the type "to use". How could I solve this problem? Is it possible to create an instance in kubernetes, from postgre, which already comes with the standard collate pt_BR? Is there anything in the django application that I can choose the collate I will use? I need help! -
