Google Analytics not filtering internal traffic
I know there have been similar questions in the past but I have tried many solutions given online to no avail. I am just not able to hide internal traffic for Google Analytics on my Django site. I am setting the filter from Admin->View->Filters. Have tried Predefined and Custom both with fixed IP as well as a regex pattern. (Yes, I have double checked my IP from whatismyip.com and I am using the right one) I read somewhere that it takes time for the filters to come into effect, so even waited for 24 hours but I still see a lot of internal traffic. Google Tag Assistant is also tracking the pages when I access them from internal IP (not sure if its supposed to know about the filters) Not sure where could I be going wrong. -

Django: use sudo to run server in virtual environment
I got Django set up on my server. I have activated my virtual environment and I'm able to run server successfully on port 8000: python manage.py runserver I would like to use port 80 so I'm able to access (test) my app from outside so I use: sudo python manage.py runserver But this gives me an error: Traceback (most recent call last): File "manage.py", line 17, in <module> "Couldn't import Django.

Django unexpectedly splitting queryset objects on spaces
I'm having a problem where Django, or a form, is splitting object list items on spaces. If the object_list is something like: ["picture"='image1.jpg "dir_as_title"='UnknownArtist', "picture"='image2.jpg' "dir_as_title"='Unknown Artist'] and I run it through the following: <div> {% for obj in object_list %} <div class="col-md-6" style="background:url({{obj.picture}}); background-size: 100% 100%; min-height: 260px; max-width: 480px;" > <form id="form" method="POST"> {% csrf_token %} <input type="submit" value={{ obj.dir_as_title }} name={{ obj.dir_as_title }} class="btn btn-primary btn-lg btn-block"/> </form> </div> {% endfor %} </div> The first item will be fine, displaying 'UnknownArtist' in the button, and passing 'UnknownArtist' as its input. The second item will display the button as 'Unknown', and appears to pass no value, resubmitting its current state. -
Django TransactionTestCase / Pending operation error (SQL Server)
I'm upgrading my Django project from: Django 1.5 / Python 2.7 → Django 1.11 / Python 3.5. The database used is MS SQL server, coupled with pyodbc + MS ODBC Driver 13. After upgrading, I am encountered a baffling error causing unit tests to fail that I just can't seem to find a solution for. The error encountered in tests using TransactionTestCase is: pyodbc.Error: ('4', '[42000] [Microsoft][ODBC Driver 13 for SQL Server][SQL Server] This operation conflicts with another pending operation on this transaction. The operation failed. (3970) (SQLExecDirectW)') My suspicion is that something to do with TransactionTestCase has changed between Django 1.5 and 1.11. However, despite by best efforts to look at the release notes and test various documented changes I cannot get my tests to pass on 1.11 as they were on Django 1.5. Nothing particularly significant, apart from the Django version, has changed. Any direction or help at all would be especially appreciated. -

sessionid cookie being removed after authentication
I've got a super weird issue regarding authentication with Django. Currently I have a multi-tenant site up and running at site.com and staging.site.com. When attempting to login on site.com, it all works correctly, the session is created in the database, and the cookie is set. When attempting to login on tenant.site.com, the session is created in the database, the cookie is set, but on subsequent page loads the cookie for sessionid is removed, therefore automatically logging the user out. Response headers are the same for both sites: content-encoding:gzip content-type:application/json date:Fri, 04 Aug 2017 00:15:07 GMT server:nginx/1.6.2 set-cookie:csrftoken=5VN5QvrQFUv6M8SN6MZTlqqQA8Tvjlki; expires=Fri, 03-Aug-2018 00:15:07 GMT; Max-Age=31449600; Path=/ set-cookie:sessionid=3f8t6p60u7fgoks0vw7sgay5j66xfuos; expires=Fri, 18-Aug-2017 00:15:07 GMT; httponly; Max-Age=1209600; Path=/ status:200 vary:Accept-Encoding vary:Cookie x-frame-options:SAMEORIGIN I've also got staging running at staging.site.com and tenant.staging.site.com, both of these work correctly. The same instance serves both site.com and tenant.site.com, there are no different configurations, the database it automatically selected via django-tenant-schemas. -

jQuery - changing colours based on numeric value and iterating through each item individually
Trying to replace the stroke colour of a percentage circle for each item rendered in django project. So far, I have only managed to change the colour to red. I suspect this is because it is changing them all based on the first/last record(percentage) retrieved. Is there a way to iterate through each item in jQuery so that the stroke colour will change per item? current code: $(function() { var score = ($("#percentage").text()); if (score <=40) { $("path").css("color", "red") } else if (score >=40) { $("path").css("color", "green") } }); -

how to change behaviour in admin interface?
This is my models.py class Club(models.Model): date = models.DateField() class Party(models.Model): title = models.CharField(max_length=100) club = models.ForeignKey(Club, null=True) date = models.DateField() I want to be able to add data through the admin interface, and I implemented it successfully. Now, The problem is that I have 2 types of parties: parties that are related to a club, and parties that are not. So, in the admin's interface, when adding the data, I would like the party's date field to be automatically filled with the club's date if I choose a club from the dropdown list. Otherwise If no club is chosen, then the party's date field should be populated manually. How can I achieve this? -

Why do values lists retain filters in Django?
Given the Model class below: from django.db import models class Users(models.Model): friends = models.ManyToManyField('self', symmetrical=False, blank=True) If I have a QuerySet of n Users, at least one of which has two friends, why is it that when I retrieve the User by filtering that QuerySet by a friends id and perform a .values_list() call on that QuerySet, like this: users = User.objects.all() user = User.objects.filter(friends=2) user.values_list('friends', flat=True) Results in output like so: >>> [2] But if I perform that same .values_list call on the object's friends field itself, like this: user.first().friends.values_list('id', flat=True) Results in an output of: >>> [2, 3] If these calls are being made on the same object, why is the output different? For reference, this is achieve using Django 1.10 and Python 3.5.2 -

How to normalize email field value in Django REST Serializer?
I am new to Django in general so please do not judge me harshly. I have a custom User model and I use DRF for user profile creation. I normalize the email in the create_user (method of the BaseUserManager). I cannot find the way how to also normalize the value of an email field in the API Serializer. Basically, if I pass an email that already exists in the database, but just with capital letters in the domain, it will go through the Serializer's validation, however it will hit an Integrity Error after: duplicate key value violates unique constraint "accounts_user_email_key" DETAIL: Key (email)=(email@example.com) already exists. Here is a shortened version of my UserManager method: class UserManager(BaseUserManager): def create_user(self, email, first_name, last_name, password): #some validation logic #... user = self.model( email=self.normalize_email(email), first_name=first_name, last_name=last_name ) user.set_password(password) user.save() return user #other stuff... Here is a Serializer itself: class UserSerializer(serializers.ModelSerializer): class Meta: model = models.User fields = ('email', 'first_name', 'last_name', 'password') extra_kwargs = {k: {'write_only': True} for k in fields} #some password validation... def create(self, validated_data): user = models.User.objects.create_user( email=validated_data['email'], first_name=validated_data['first_name'], last_name=validated_data['last_name'], password=validated_data['password'] ) return user Here is the view: class UserCreate(generics.CreateAPIView): serializer_class = serializers.UserSerializer -

Django - window.open inside template not working
