How do I extend and Add extra views and urls, in the default Django Oscar restful API?
Django oscar does not provide a user registration API, so I am trying to add an API, for it. so that I can access the register API, from API root the same way I am accessing other APIs provided by oscar. Django 2.2.10 django-oscar 2.0.2 django-oscar-api 2.0.2 What I tried: urls.py(root) #OSCAR DEFAULT RESTful JSON API path("api/", include("oscarapi.urls")), apps.py class OscarAPIConfig(AppConfig): name = 'oscarapi' def ready(self): super().ready() def get_urls(self): urls = super().get_urls() urls += [ url(r'^register/$', views.UserCreateAPIView.as_view()), ] return self.post_process_urls(urls) views.py class UserCreateAPIView(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = RegistrationSerializer permission_classes = (AllowAny,) urls.py router = routers.DefaultRouter() router.register('users', views.UserCreateAPIView) urlpatterns = [ # url(r'^register/$', UserCreateAPIView.as_view()), path(r'^', include(router.urls)), ] -
Django i18n translations not working in production (Heroku)
My translations are working locally, but in production at Heroku, my site remains in its default language (English) after changing the language. These are in my settings.py file: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) USE_I18N = True USE_L10N = True LOCALE_PATHS = [os.path.join(BASE_DIR, 'locale')] This is my structure: myproject βββ Procfile βββ locale β βββ fr β βββ LC_MESSAGES β βββ django.mo β βββ django.po βββ myproject β βββ __init__.py β βββ settings.py I thought it was a path issue so I SSH'd into my Heroku app and printed LOCALE_PATHS: >>> from myproject.settings import LOCALE_PATHS >>> print(LOCALE_PATHS) ['/app/locale'] And pwd in locale/ returns pwd /app/locale. What did I do wrong? -
Django when clicked show another model attribute
I'm trying to make window where some text will be shown in one language, when clicked second language will appear. I've created one model which consists every information about post. model.py from django.db import models from datetime import datetime from django.contrib.auth.models import User def get_default_user(): return User.objects.get(id=1) class EveryPost(models.Model): title_pl = models.CharField(max_length=100, blank=True) title_ru = models.CharField(max_length=100, blank=True) text_pl = models.TextField(blank=True) text_ru = models.TextField(blank=True) date = models.DateTimeField(default=datetime.now, blank=True) User = models.ForeignKey(User, on_delete=models.CASCADE, default=get_default_user) def __str__(self): return self.title_pl html {% for obj in EveryPost %} <div class="card text-center"> <div class="card-header"> <ul class="nav nav-tabs card-header-tabs"> <li class="nav-item"> <a class="nav-link nav-main" href="{% url 'rupl' obj.pk %}">PL</a> </li> <li class="nav-item"> <a class="nav-link nav-main" href="{% url 'plru' obj.pk %}">RU</a> </li> </ul> </div> <div class="card-body"> <h5 class="card-title"><a href="{% url 'detailpost' obj.pk %}">{{ obj.title_pl }}</a></h5> <p class="card-text">{{ obj.text_pl|truncatechars:350 }}</p> <a href="{% url 'detailpost' obj.pk %}" class="btn btn-dark float-right">Zobacz </a> </div> <div class="card-footer text-muted"> <span class="float-left">{{ obj.date|date:"d M y" }}</span> <span class="float-right">PrzesΕane przez: {{ obj.User }}</span> </div> </div> {% endfor %} I've tried to make switch between text_pl and text_ru but it wasn't a good idea(lost data) views.py def plru(request, pk): post = EveryPost.objects.get(pk=pk) post.text_pl = post.text_ru post.title_pl = post.title_ru post.save() return redirect('index') def rupl(request, pk): post = EveryPost.objects.get(pk=pk) β¦ -
Implementing Json schema in my django restframework
I'm new in DJango and I'm trying to Implement a log collector system, which gets logs in Json format from different systems. My first challenge is that these systems generate different fields and I don't know how to define dynamic fields in my model for storing logs in my database which is PostGre. I mean that my json files define various fields in each request, so I can't use a single model for this purpose. The second challenge is that before arrival of Json log, a scheme will be sent to system to define my Json files properties as follows. My question is that, how I can implement such a system to get these data and help me with storing Json files when they arrive?: { namespace: βstringβ, schema: { field_1: type1, field_2: type2, β¦ } } "namespace" defines a specific structure in my system cause my system's clients can send multiple log types to my log collector.

Django i18n_patterns default language
I am using i18n_patterns to change the language prefix. It s working fine ones the language cookie was set. The problem is that it's adding /en/ when I trying to access a page without the language code in private window, even though my preferred language is not en (the default one set in settings.LANGUAGE_CODE). I have found how Django discovers language prefference First, it looks for the language prefix in the requested URL.Failing that, it looks for the LANGUAGE_SESSION_KEY key in the current userβs session.Failing that, it looks for a cookie. The name of the cookie used is set by the LANGUAGE_COOKIE_NAME setting. (The default name is django_language.) Failing that, it looks at the Accept-Language HTTP header. This header is sent by your browser and tells the server which language(s) you prefer, in order by priority. Django tries each language in the header until it finds one with available translations. Failing that, it uses the global LANGUAGE_CODE setting. So the reason why I get /en/ prefix in my url, when there is no any cookie set is because of the Accept-Language HTTP header. How can i solve that if somebody visits my site for the first time when there is β¦ -
Django: different access types for different urls
In my Django project, I defined my URLs in urls.py file as below: from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^api/', include('page1.urls')), url(r'^api/', include('page2.urls')), url(r'^remote/', include('registering.urls')), ] with ALLOWED_HOSTS definition in settings.py file, both /remote and /api has the same access from type, so if ALLOWED_HOSTS is ALLOWED_HOSTS = ['*'] So both /api and /remote URLs are remotely accessible. But if ALLOWED_HOSTS is: ALLOWED_HOSTS = ['localhost'] So both /api and /remote URLs are not remotely accessible, and are accessible only from localhost. But what I need is that only /remote URLs are remotely accessible. And /api should be accessible only from localhost and not allowed to access from remote. I there an idea to achieve that? -

I have the following code which copies content from already existing app to another slots keeping in mind that only new data gets added. However, I have optimized the code as I could.

How to make multiple template tags work separately?

Django auto increment model
I design Django Model as shown below : ` class User(models.Model): id-models.AutoField(primary_key=True) username=models.CharField(max_length=25,verbose_name="username") name=models.CharField(max_length=20,default="noName",verbose_name="name") password=models.CharField(max_length=20,verbose_name="password") email=models.EmailField() userCode=models.CharField(default=" ",max_length=100,verbose_name="User Code") def __str__(self): return self.username class Meta: ordering = ['-username']` Then I create an object in view.py. Although id is auto incremented, python want me to define an id. View.py is shown below. def register(request,id): if request.method=='POST': form = RegisterForm(request.POST) if form.is_valid(): username = form.cleaned_data['username'] name=form.cleaned_data["name"] password = form.cleaned_data["password"] email=form.cleaned_data.get("email") newUser = User(1,username,name,password,email) newUser.save() return redirect('mainPage') else: form=RegisterForm() context = { "form" : form, "id":id } return render(request,"SignupLogin.html",context) User(1,username,name,password,email) in that line, 1 is the id number. When I delete it, error which is about missing variable id, is thrown. How can I get rid of 1? -

Django: how to add a product in function based view in restapi
In my company, i suggested to my co-developer to use 'generic-class' based view to add,update product but my senior developer said that to use 'function' based view and also use raw query instead of ORM, fetch data from sql db instead of define the schema in my models. i think this is very lengthy process, i am too much confused about how to start. here is my views to show list of item, but i am confused about how can i add and update item. import MySQLdb from pro.settings import connection cur, conn = connection() class Product_ListAPIView(APIView): def get(self,request,format=None): cur,conn = connection() query = ''' SELECT * FROM product_images ''' with conn.cursor(MySQLdb.cursors.DictCursor) as cursor: cursor.execute(query) result = cursor.fetchall() data = list(result) print(request.data) return Response({"product_data":result},status=status.HTTP_200_OK) # except Exception as e: # return Response({"data":"except block"}) it would be great if anyone suggest me for any helpful tutorial or could give me any helpful information then would be much appreciated. thank you! -

Postgre SQL ignore the filtering condition if the value is null
I have the following three variables passed to the query A,B and C. A, B and C can take any values including null.

How do I ensure that null fields are not inserted in mongodb, from django, using djongo connector?
