Remove wagtail from django app, and wagtail db tables from postgres
How do I go about removing an errant wagtail install from a django project. Actually, I just want to remove the postgres tables. I accidentally was pointing to a wrong secrets file and used a database for another django project, so I have wagtail tables. I can easily drop the wagtail tables, but are there other things I need to drop? I'm thinking my django_migrations table has info I shouldn't have. -

Django/Python unable to find GDAL Library
I have installed GDAL in a virtual environement with the following commands: $ brew install gdal $ pip3 install gdal When trying a python manage.py makemigrations or python manage.py runserver (or whatever) on the website code for which I installed it, I'm running into the following error: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal", "GDAL", "gdal2.4.0", "gdal2.3.0", "gdal2.2.0", "gdal2.1.0", "gdal2.0.0").

I have no experiences with GDAL, at this stage I just need to install it properly to make the website run on my machine and start contributing to the code. Any help would be appreciated. -

DRF Could not resolve URL for hyperlinked relationship using view name on PrimaryKeyRelatedField
I have a frustrating problem with POST requests on a DRF serializer - DRF is, for some reason, going to an incorrect view name, and view_name is not a settable property on PrimaryKeyRelated Field. Models: (the class with the issue) class Section(models.Model): teacher = models.ManyToManyField(Teacher) (a class that works, using the same pattern) class Assessment(models.Model): standards = models.ManyToManyField(Standard) Serializers: (doesn't work) class SectionInfoSerializer(serializers.HyperlinkedModelSerializer): url = serializers.HyperlinkedIdentityField(view_name="gbook:section-detail") teacher = BasicTeacherSerializer(many=True, read_only=True), teachers_id = serializers.PrimaryKeyRelatedField(write_only=True, queryset=Teacher.objects.all(), many=True, source='teacher', allow_empty=False) class Meta: model = Section fields = '__all__' read_only_fields = ['sendEmails', 'teacher', 'course'] (works) class AssessmentSerializer(serializers.HyperlinkedModelSerializer): pk = serializers.PrimaryKeyRelatedField(read_only=True) url = serializers.HyperlinkedIdentityField(view_name="appname:assessments-detail") standards = serializers.PrimaryKeyRelatedField(read_only=True, many=True) standards_id = serializers.PrimaryKeyRelatedField(queryset=Standard.objects.all(), source='standards', write_only=True, many=True, allow_empty=False) class Meta: model = Assessment fields = '__all__' urls: router.register(r'teachers', teacher_views.TeacherViewSet, basename='teacher') router.register(r'sections', course_views.SectionViewSet) router.register(r'standards', gbook.views.standard_views.StandardViewSet, basename='standards') router.register(r'assessments', AssessmentViewSet, basename='assessments') I'm using the _id fields during POST and PUT to send the id's of the related obejcts, then serializing them. This worked great with AssessmentSerializer (and several others), but is failing for a reason that I can't figure out. Certainly, the appname is missing from the view returned in the error, but I don't know why that's happening, and why it didn't happen before.

Updating related objects django rest framework
In my django project, I have 2 relevant models: class User(AbstractUser): email = models.EmailField( verbose_name='e-mailaddress', max_length=255, unique=True) # other props not important class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) #other props not important For both creating and retrieving, it is convenient to have User as a nested object in the serializer: class ProfileSerializer(serializers.ModelSerializer): user = UserSerializer() class Meta: model = Profile fields = '__all__' def create(self, validated_data): user_data = validated_data.pop('user') user = User.objects.create(**user_data) user.save() # because of reasons, an empty profile is created on initial save. This works, trust me d, _ = Profile.objects.update_or_create(user=user, defaults=validated_data) d.save() return d HOWEVER. One action that I want to be possible as well is to update both properties of the Profile and the User at the same time. When doing this with my serializer, serializer.is_valid() fails as the provided email is already present in the database. This also indicates that, even if the validation passes (i.e. because of an updated email address), a new User object will be created and coupled to the Profile. So my question is: How do I update properties of the profile and its related user without creating a new user? -

How can I run different projects for the same domain address?
I know very little about the deployments of projects. I want to run different projects for the same domain address. Maybe these projects can be web, desktop, etc. I use Django and Python technologies for these projects. Examples: www.companyname.com/project1/... www.companyname.com/project2/... www.companyname.com/project3/... How should I go about a problem like this in Python? I have no experience with deploy stages. What structure can be used for such a thing? How can I make this system more effective. Docker and aws are enough for such a problem? How should I go about this challenge? Thank you for replies. -

Django: Adding object using a reverse relation in ManyToMany relationship

Rolling 12 months regardless of year in Django
How would I go about setting up a rolling 12 month period in Django without any year. I am trying to plot the academic year but the problem I am finding mainly due to my lack of knowledge is that I have to set the year in datetime The academic year runs from beginning of April to the End of March the following year, therefore the easiest way for me to calculate this I guess is to provide a rolling 12 months or to set the date regardless of the year. As always, thank you for the help. -

Django - is it possible to include two templates with different styles?
I created a template on my Django app, it uses it's own CSS files and its own style. Now i would like to add on top of this template my own navbar that i'm using on the rest of the app. The problem is that the navbar has its own styles, and the template has its style too, so mixing them messes up both the navbar and the rest of the template. I thought that using include instead of extends would fix my problem, but the i problem is that when i try with template.html {% include 'navbar.html' %} ... the two parts will still collide. Is there any way to import an element in a template without applying all the styles of the element to the rest of the template in Django? Or is mine a CSS problem and i should solve it there? Any kind of advice is appreciated. -

COMPANY</h2> </a> <a class="carousel-item" href="/stone_island"> <img class='carouselitem' src="{% static 'images/stone_island.jpg' %}"> <h2 class="bottom-left">STONE ISLAND</h2> </a> <a class="carousel-item" href="/ma_strum"> <img class='carouselitem' src="{% static 'images/mastrum.jpg' %}"> <h2 class="bottom-left">MA.STRUM</h2> </a> <a class="carousel-item" href="/barbour"> <img class='carouselitem' src="{% static 'images/barbour_lookbook.jpg' %}"> <h2 class="bottom-left">BARBOUR</h2> </a> <a class="carousel-item" href="/lacoste"> <img class='carouselitem' src="{% static 'images/lacoste_banner.jpg' %}"> <h2 class="bottom-left">LACOSTE</h2> </a> <a class="carousel-item" href="/perry"> <img class='carouselitem' src="{% static 'images/perry_banner.jpg' %}"> <h2 class="bottom-left">FRED PERRY</h2> </a> <a class="carousel-item" href="/paul_shark"> <img class='carouselitem' src="{% static 'images/paul_shark_banner.jpg' %}"> <h2 class="bottom-left">PAUL & SHARK</h2> </a> <a class="carousel-item" href="/napa"> <img class='carouselitem' src="{% static 'images/napa_banner.jpg_large' %}"> <h2 class="bottom-left">NAPAPIJRI</h2> </a> <a class="carousel-item" href="/tnf"> <img class='carouselitem' src="{% static 'images/tnf_banner.jpg' %}"> <h2 class="bottom-left">THE NORTH FACE</h2> </a> </div> CSS: img.carouselitem{ height: auto; } Thanks in advance! -
Order of Operations Django Templates
I have a float variable mynumber in Django templates, and I need to round it to the nearest integer without third party filters, so I'm following this logic: int(mynumber - 0.5) + 1 In Django templates I can do this: {{ mynumber|add:"-0.5"|add:"1" }} But the problem, as you can see, is that there is no order of operations, so I get a different number than the expected, how can I solve this?
