How to override the javascript default editable bootstap values
I am stuck at overriding the default editable bootstrap values in Django framework javascript html page In my webpage, it coded as below $.fn.editable.defaults.url = "{% url 'page1' model.PATH %}"; Now my requirement is, When I click on a button, it check the views.py(page1, which is default URL) and pass the context through 'return HttpResponse' to html page that "True" or "False" based the value, if fasle, it should go page2, it never goes to page2 url,its entered to the function conflict_warn() but not inside and eventually it failed with the "Uncaught TypeError:e.getAttribute is not a function", I tried number of way, but all are vain. $(this).editable({ value: "", display: false, success:function(response, newValue){ if (response.hasOwnProperty("State"))){ conflict_warn(response, newValue)//if State value True,should go to other func } else{ window.location.href = "{% url 'path1' 'path2'%}" + response; } }, error:function(response, newValue){$(this).editable("destroy");} }); $(this).editable("submit"); function conflict_warn(response, newValue){ $(this).editable({ value:"" display: false success: function(response.newvalue){ window.location.href = "{% url 'path1' 'path2'%}" + response; } }); $(this).editable("setValue","{% url:'page1' model.PATH %}"); $(this).editable("submit"); } -
'User' Object has no attribute 'method'
I am just playing around with the Django login and logout phase. I have a login page, if the user gets it with 'GET', he gets the form, if he submits the form, it gets submitted to the same view.login function. The problem is that when i try to use ' if request.method=='POST'. I get an error that 'User has not attribute method', i don't understand, why does the 'User' object gets passed instead of the request object? Here's the code of views.py: from django.shortcuts import render from django.http import HttpResponse, Http404, HttpResponseRedirect from .models import Flight,Passenger from django.urls import reverse from django.contrib.auth import authenticate,login, logout from django.contrib.auth.models import User def index(request): if not request.user.is_authenticated: return render(request,"login.html") context={ "flights":Flight.objects.all() } return render(request,"index.html",context) def flight(request,flight_id): flight= Flight.objects.get(pk=flight_id) passengers = flight.passengers.all() non_passengers = Passenger.objects.exclude(flight=flight).all() context={ "flight":flight, "passengers":passengers, "non_passengers":non_passengers } return render(request,"flight.html",context) def book(request,flight_id): passenger_id = int(request.POST["passenger"]) flight = Flight.objects.get(pk=flight_id) passenger = Passenger.objects.get(pk=passenger_id) passenger.flight.add(flight) return HttpResponseRedirect(reverse("flight",args=(flight_id,))) def login(request): print("\n In LOGIN \n") if request.method=='POST': print("\n In POST Request \n") username = request.POST["name"] password = request.POST["password"] user = authenticate(request,username=username,password=password) if user is not None: login(user) return HttpResponseRedirect(reverse("index")) else: return render(request,"login.html") Here's the login page: <html> <head> <meta charset="utf-8"> </head> <body> <form action="{% url 'login' … -

Deploying Django + Angular to EB without using django templates in production
I've been reading a million answers in this subject but I can't find a solution that works. I have a Django DRF backend that is used for all the API calls and a separate Angular(5) front-end project. The Django backend is deployed to Elastic Beanstalk and is working properly. All I want to do is to deploy the angular frontend without needing to add template tags to the htmls. Better yet I don't want to change anything in the built dist Angular folder. I see there are several approaches - As far as I can understand the best one would be to serve the index.html through a regular Django url and then expose all the dist folder (the static files). I achieved the first part using: urlpatterns += [ url(r'^$', TemplateView.as_view(template_name='index.html')), url(r'^(?P<path>.*)/$', TemplateView.as_view(template_name='index.html')), ] and defining the dist folder as a template folder in settings.py: ANGULAR_APP_DIR = os.path.join(BASE_DIR, 'client/dist') TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ANGULAR_APP_DIR], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.template.context_processors.i18n', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] Currently, I define an s3 bucket to hold all static files and 'collectstatic' works and puts all the static files in the right location, including the files in … -
Updating a value in serialzier after accessing .data in Django Rest Framework
I have a serializer for my Post class which has a image and a link attribute. media is an FileField and link is a URLField which is a url to somewhere else I share my post (in another website.) I want to: Submit my post data (text, and the image) Accessing the url of submitted file to use in sharing it in another place. Updating the link value after I found it. This is what I tried: post = PostCreateSerializer(data=request.data, context={'request': request}) post.is_valid(raise_excpetions=True) post.save() media_url = post.data.get('media') link = find_link_value() post.link = link post.save() This raises an exception. says: You cannot call `.save()` after accessing `serializer.data`.If you need to access data before committing to the database then inspect 'serializer.validated_data' instead. The problem is when I use post.validated_data.get('media') instead of .data, it doesn't give me the url. It gives me an InMemoryUploadedFile object, that of course, doesn't have any path and url. I thought I could use name attribute of InMemoryUploadedFile object to create the url (the file is actually saved in disk and I wonder why this is InMemory!) but when the name is duplicate, the real name of file in disk and url differs from it's original name (for … -

How to retrieve models data having nested relationship using serializers in Django Rest Framework?
i am explaining in detail about a problem that i am facing and seek help from this community. I followed this Django Rest Framework documentation but couldn't get the desired result for multi-level nesting Consider the relationship of models as explained : A user can have multiple Workspaces A workspace can have multiple Projects A Project can have multiple ProjectLists ProjectList can have multiple Tasks Tasks can have multiple updates User | Workspaces (ForeignKey="User") |____Projects (ForeignKey="Workspaces") |____TodoList (ForeignKey="Projects") |____Tasks (ForeignKey="TodoList") |____Updates (ForeignKey="Tasks") So what i want is to get all the data that a User has in a nested json format like this: [ { "workspace_id": "99a961ec-b89e-11e8-96f8-529269fb1459", "workspace_owner": "1", "workspace_title": "Indie Dev Works", "projects": [ { "project_id":"db09cfa0-b89e-11e8-96f8-529269fb1459", "todo_list":[ { "list_id": "9dc64e4c-b89f-11e8-96f8-529269fb1459", "list_name":"Project list -1", "tasks":[ "task_name":"Create HTML docs", "updates":[ { "id":"d5eb660e-b89f-11e8-96f8-529269fb1459", "text":"Creating using PUG" }, { ..... ..... ..... ..... }, ] ] } ] }, { "project_id":".........", .... .... .... .. .. . }, ] } ] So when my User logs in by entering email, i am trying to get all the Workspaces instance and then pass it to the serializers in my views as mentioned below: views.py class InitializeHome(viewsets.ViewSet): def list(self,request): user_email = request.user.email user_instance = utils.getUserInstance(user_email) … -
__month and __year creating query with Between clause from wrong year, with timezone activated
I have a model with createdon datetime field. My env is timezone sensitive. NOw I want to get total/aggregated value by date of current month and year. (ie.g. each date of today's month year totalled) k=model.objects.extra({'created_on':"date(createdon)"}).filter(createdon__month=date.today().month,createdon__year=date.today().year).values('created_on').annotate(total_created=Count('id')).order_by('created_on') I have records but it returns empty result set. And the query that was actually executed looks like this: SELECT (date(createdon)) AS 'created_on', COUNT(app_model.id) AS total_created FROM app_model WHERE app_model.createdon BETWEEN 2017-12-31 22:00:00 AND 2018-12-31 21:59:59 AND EXTRACT(MONTH FROM CONVERT_TZ('app_model.createdon','UTC', Europe/Istanbul)=9 GROUP BY date(createdon)) Timezone is really vital to the app so it won't be turned off. But is there away to fix te query so I get the members who are actually registered in Sep, 2018? -

Here's my Django code: views.py from rest_framework import generics from .models import Item from .serializers import ItemSerializer class ItemList(generics.ListCreateAPIView): queryset = Item.objects.all() serializer_class = ItemSerializer class ItemDetail(generics.RetrieveUpdateDestroyAPIView): queryset = Item.objects.all() serializer_class = ItemSerializer items/urls.py from django.urls import path from .views import ItemList, ItemDetail urlpatterns = [ path('', ItemList.as_view()), path('<int:pk>/', ItemDetail.as_view()), ] project/urls.py from django.contrib import admin from django.urls import include, path from rest_framework_jwt.views import obtain_jwt_token urlpatterns = [ path('items/', include('groceries.urls')), path('admin/', admin.site.urls), path('api-auth/', include('rest_framework.urls')), path('api-token-auth/', obtain_jwt_token), ] settings.py REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', ), } I'm thought the issue would have to be with Django, but I am able to get what I expect with curl -H "Authorization: JWT <token>" http://localhost:8000/items/ If … -
use django-filter with object url_params
I have successfully implemented django-filter on my Django-rest-framework server. I have the following filter_class filters.py class EmploymentFilter(filters.FilterSet): class Meta: model = EmploymentCheck fields = ['instructions',] views.py class EmploymentCheckViewSet(viewsets.ModelViewSet): pagination_class = ContentRangeHeaderPagination serializer_class = EmploymentCheckSerializer queryset = EmploymentCheck.objects.all() filter_class = EmploymentFilter the filter works when i send a get request as /employmentcheck/?instructions=2 However, I have implemented a front end with react-admin. My front-end, sends a request with the url_params as objects /employmentcheck/?filter={"instruction_id":"2"}&range=[0,24]&sort=["id","DESC"]/ Notice how the URL specifies a filter object, in which, it defines the parameters to filter against. My question is, how and where can I filter my model without changing the URL pattern from my client? Any other advise that spans the scope of my question is equally welcomed Models.py class EmploymentCheck(models.Model): instructions = models.ForeignKey(Instruction, on_delete=models.CASCADE, null=True) -

form is not shown despite being nested to company model
The use case of the app I am trying to develop is about registering the company who are interested for franchise. I have taken this concept from franchisebazar for learning purpose. There i saw company info, brand info and business model for registering the company. That is why I created the following model. I want the create and update view now so from the frontend i can hit the api request to create and update. I designed the following serializer and APIView. However, when i try to test in the browser, if the coded way is working or not, i could not see the form for brand and business model despite they are nested in company. Thus, I want to know if i have to extend it more by creating a view for brand and business model separately or i did something wrong in my code. class Company(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE, null=True) name = models.CharField(max_length=150, blank=False, null=False) phone_number = models.CharField(max_length=15, blank=False, null=False) class Brand(models.Model): company = models.ForeignKey(Company, related_name='company_brand', on_delete=models.CASCADE) name = models.CharField(max_length=150, blank=False, null=False) website = models.URLField() description = models.TextField(blank=False) class BusinessModel(models.Model): company = models.ForeignKey(Company, related_name='company_business_model', on_delete=models.CASCADE) industry = models.ForeignKey(Industry, null=True, related_name='industry', on_delete=models.SET_NULL) segments = models.ForeignKey(Segment, on_delete=models.SET_NULL, null=True) total_investment … -
Correct way of using Django update_or_create
this is my model class services(models.Model): Invoice_number = models.CharField(max_length=100) name = models.CharField(max_length=100) contact = models.IntegerField() email = models.EmailField() service = models.CharField(max_length=30) This is the query I am trying to update or create an instance in the above model services.objects.update_or_create(Invoice_number = self.a, name=self.b, contact=self.c, email =self.d, service =self.d ) So if an Invoice_number exists the instance should get updated if not then create a new instance.
