Integrate Django blog project in HTML website
I have a regular website where HTML5, CSS3, JQUERY and static images have been used. I also have a Blog written in Django and I would like to integrate it in the website. I am really new to Django so I was wondering which is the best approach to use. Should I integrate the website code as part of the Django project or there are some other solutions? thanks! -

Django loaddata ignore existing objects
I have a fixture with list of entries. eg: [ { "fields": { "currency": 1, "price": "99.99", "product_variant": 1 }, "model": "products.productprice", "pk": 1 }, { "fields": { "currency": 2, "price": "139.99", "product_variant": 1 }, "model": "products.productprice", "pk": 2 } ] This is only initial data for each entry (The price might change). I would like to be able to add another entry to that fixture and load it with loaddata but without updating entries that already exist in the database. Is there any way to do that? Something like --ignorenonexistent but for existing entries. -
Serialize model fields related through another model
I have three models linked like so: class A: some fields class B: ForeignKey('A') class C: ForeignKey('B') Now, when I serialize C, I want to serialize model fields from A. Of course, this can be done using nested serializers like so: class ASerializer: class Meta: model = A fields = ('id', some fields) class BSerializer: a_s = ASerializer(read_only=True) class Meta: model = B fields('id', 'a_s') class CSerializer: b_s = BSerializer(read_only=True) class Meta: model = C fields('id', 'b_s') However, I want to only display the fields of related A objects when serializing C (without using BSerializer). How do I do this? -

custom email authentication backend not working in django 2.1.4
I am having trouble in integrating custom authentication backend in django 2.1.4 . Following is my code : my FMS.authBackend module : from django.contrib.auth import get_user_model from django.contrib.auth.backends import ModelBackend class authEmailBackend(ModelBackend): def authenticate(self, username=None, password=None, **kwargs): print("aaaaaaa") UserModel = get_user_model() try: user = UserModel.objects.get(email=username) except UserModel.DoesNotExist: return None else: if user.check_password(password): return user return None my settings.py : AUTHENTICATION_BACKENDS = ( 'FMS.authBackend.authEmailBackend', 'django.contrib.auth.backends.ModelBackend', ) my urls.py : from django.contrib.auth import views as auth_views urlpatterns = [ path('login', my_decos.logout_required(auth_views.LoginView.as_view(template_name = 'register/login.html')),name = 'login') ] The above code is not working in my case. Function authenticate in authEmailBackend is never called as nothing printed in console but I print statement in authenticate function. although the same code was working for django 2.0.8, the only difference then was that the urls.py was : from django.contrib.auth import views as auth_views urlpatterns = [ path('login', my_decos.logout_required(auth_views.login(template_name = 'register/login.html')),name = 'login') ] but in the newer django the django.contrib.auth.views.login doesn't support any more and we need to use django.contrib.auth.views.LoginView. I read somewhere that to use custom AUTHENTICATION_BACKEND our url must point to django.contrib.auth.views.login but which is not possible here. So can you please help me to overcome the problem. -

what does get_expiry_age() return in Django
Instead of returning actual seconds left for expiry, request.session.get_expiry_age() returns fixed value=10 set in request.session.set_expiry(10). But when I manually set request.session['var1']=1 in homepage and then try to print this var1 in another view, I get KeyError after 10 seconds, saying 'var1' doesnt exist. So this session does expire after 10 seconds. So ideally if i wait on homapge for 5 seconds and then move to another view, request.session.get_expiry_age() should return 5 seconds instead of 10 seconds. Django doc contradict this observation. Is there any other inbuilt function that can show actual seconds left for session expiry. Thanks -

Dynamically create serializer based on model field value
I have a model like so: class A: name = models.CharField() group = models.ForeignKey('SomeModel', null=True, blank=True) When I serialize this, I would like the serielizer to have different formats based on whether the 'group' field is blank or not. Of course this can be achieved by having different serializers for different formats and calling them as required in the View layer: class TypeASerializer(serializers.ModelSerializer) class Meta: model = A fields = ('id', 'name') class TypeBSerializer(serializers.ModelSerializer) class Meta: model = A fields = ('id', 'name', 'group') But I wanted to handle it in the serializer layer itself and have a single serializer for this. Is that possible? -
