Problems referencing model in function based view
As the title states, I'm having trouble referencing my account model in my cmsUserDetailEdit view. The site itself doesn't break, but it seems like its just not able to find the model, as all the placed where the model is referenced is empty. I've tried placing the account in the context. E.g: 'account': account, but without luck. views.py def cmsUserDetailEdit(request, pk): account = Account.objects.all() accounts = Account.objects.get(pk=pk) if request.method == 'POST': u_form = UserEditPersonalForm(request.POST, instance=accounts.user) a_form = AccountEditPersonalForm(request.POST, instance=accounts) if u_form.is_valid() and a_form.is_valid(): u_form.save() a_form.save() messages.success(request, f'Account updated') return redirect('/cms/test/') else: u_form = UserEditPersonalForm(instance=accounts.user) a_form = AccountEditPersonalForm(instance=accounts) context = { 'u_form': u_form, 'a_form': a_form, } return render(request, 'cms/users/cms-users-user-edit.html', context) cms-users-user-edit.html <div class="note-card-content"> <div class="content"> {{ account.note }} <!-- This part is empty --> </div> </div> -
Django Rest Framework ViewSets is returning selected records rather than all records in list view
I have a django application. I have one part of my app that is not working as I was expecting. As of now I am using the django rest framework view sets. What I want is two basically have 2 different list views in the same viewset. 1 that returns all of the accounts in the accountviewset and another list view that returns all of the accounts associated with a user based on the user foreignkey in the account model. The code below returns all the acccounts associated with a specific person, but I am not able to have a list view that returns all of the accounts in the database. class AccountViewSet(viewsets.ModelViewSet): serializer_class = AccountSerializer queryset = Account.objects.all() lookup_field = 'user__username' def list(self, request): queryset = Account.objects.all() serializer_class = AccountSerializer def get_object(self): return self.queryset.get(user__username=self.kwargs.get('username')) -
Django: Get queryset of nested objects in Retrieve API View
I'm creating a Django application with django-rest-framework and using djongo to connect to MongoDB. I have a nested model as such: class Group(models.Model): group_code = models.CharField( max_length=15, blank=False, unique=True ) users = models.ArrayModelField( model_container=User ) class User(models.Model): name = models.CharField( max_length=100 ) user_code = models.CharField( max_length=32, default=hex_uuid, editable=False ) class Meta: abstract = True I'm attempting to set up a view to retrieve a User at the following URL: urlpatterns = { url(r'^user/(?P<group_code>[\w]+)/(?P<user_code>[\w]+)/$', UserDetail.as_view(), name='user-detail') } Essentially, I want the view to display just the User's information instead of the Group's information. This didn't work, but is what I attempted: class UserDetail(generics.RetrieveUpdateDestroyAPIView): serializer_class = UserFullSerializer def get_queryset(self, *args, **kwargs): return Group.objects.get(team_code=self.kwargs['group_code']).users lookup_field = 'user_code' lookup_url_kwarg = 'user_code' However, users in this case is a normal list instead of a QuerySet. Therefore, the lookup_field attribute is not working correctly. Any thoughts on how to access the nested list users of type User as a QuerySet so that this view can work properly? -

How do I run my python command as a cron while loading my environment vars?
I'm using Python 3.7 with Django. I want to set up a cron job ("crontab -e") where I run davea$ /bin/bash -l -c 'cd /Users/davea/Documents/workspace/mainpage_project; ./venv/bin/activate; python manage.py runstats' However, upon running that, I get the error File "manage.py", line 14 ) from exc If I run cd /Users/davea/Documents/workspace/mainpage_project; ./venv/bin/activate; python manage.py runstats everything runs fine, but I want to load environment variables which is why I was trying the former command.

How do I select information in other table based on the ID provided using a loop
Super new to django, working on my 1st test project. I have an app that's called customers. Inside of that, I have a few models. The 2 main, once I am trying to get to work right now, are Customer_Info, and Company_Info. On the template side I want to pull information in the for loop from both templates. Companies could have multiple customers (contacts). So inside of the customer info table, I am storing the company uuid they might belong to. Some customers would not have that ID as they are individuals and do not have a company association. Here are the 2 models. class Customer_Info(models.Model): #Name of the table id = models.AutoField(primary_key=True) cust_uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) first_name = models.CharField(max_length=32, blank=False) middle_name = models.CharField(max_length=32, blank=True) last_name = models.CharField(max_length=32, blank=False) phone = models.CharField(max_length=10, blank=False) email = models.CharField(max_length=64, blank=False) address_1 = models.CharField(max_length=64, blank=True, null=True) address_2 = models.CharField(max_length=64, blank=True, null=True) city = models.CharField(max_length=16, blank=True, null=True) state = models.CharField(max_length=2, blank=True, null=True) zipcode = models.IntegerField(blank=True, null=True) country = models.CharField(max_length=16, blank=True, null=True) company_uuid = models.ForeignKey('company_info', to_field='company_uuid', db_column='company_uuid', on_delete=models.PROTECT, blank=True, null=True) # miht need a nullable defaul https://docs.djangoproject.com/en/2.1/ref/models/fields/#foreignkey user_id = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, blank=False) # miht need a something else https://docs.djangoproject.com/en/2.1/ref/models/fields/#foreignkey date_added = models.DateTimeField(auto_now=True) def __str__(self): return … -
replace() method not working in custom template filter (Django 2.1)
I am writing a custom template filter that highlights the keyword put into the search engine in the search results page, just like in Google search results. Search engine code in view.py: def query_search(request): articles = cross_currents.objects.all() search_term = '' if 'keyword' in request.GET: search_term = request.GET['keyword'] articles = articles.annotate(similarity=Greatest(TrigramSimilarity('Title', search_term), TrigramSimilarity('Content', search_term))).filter(similarity__gte=0.03).order_by('-similarity') context = {'articles': articles, 'search_term': search_term} return render(request, 'query_search.html', context) Custom template filter code: @register.filter @stringfilter def highlight(value, search_term): return mark_safe(value.replace(search_term, "<span class='highlight'>%s</span>" % search_term)) HTML template code with the filter highlight applied to article.Content: <ul> {% for article in articles %} <li><a href="{% url 'search:article_detail' article.ArticleID %}">{{ article }}</a></li> <p> {{ article.Content|highlight:search_term }} </p> {% endfor %} </ul> CSS code for <span class='highlight'>: .highlight {color:red;} I get no error message but I don't see the highlighted effects. I tried doing other things with value.replace() here but I don't see the effects either. I think the replace() method is not working here. Maybe search_term is not recognized. Any idea what's the issue? -

Struggling to use two forms with same function based view, connecting it to specific profiles
First off, I have a model named Account which ties into Django's native User model thorough a one to one field. I'm building an admin panel, where the goal is to be able to edit registered accounts (users) information through forms on their backend profile page. I have managed to create a view using two forms (form for changing the user model and a form for changing the account model), but since the instance is request.user, I'm only able to edit my own information on the different profiles. I'm not sure how to tie the pk for account into the code. The ultimate goal is for example: http://path/to/user/profile/1 - Able to edit account 1's information http://path/to/user/profile/2 - Able to edit account 2's information I have tried to add pk to the definition of test, but without luck. urls.py urlpatterns = [ path("test/<int:pk>", views.test, name="test"), ] views.py def test(request, pk): if request.method == 'POST': u_form = UserEditPersonalForm(request.POST, instance=request.user) a_form = AccountEditPersonalForm(request.POST, instance=request.user.account) if u_form.is_valid() and a_form.is_valid(): u_form.save() a_form.save() messages.success(request, f'Account updated') return redirect('/cms/test/') else: u_form = UserEditPersonalForm(instance=request.user) a_form = AccountEditPersonalForm(instance=request.user.account) context = { 'u_form': u_form, 'a_form': a_form } return render(request, 'cms/test.html', context) -

Django CreateView - created_by, modified_by mixin not working

what is the best way/architecture to trigger celery calcualtion with many account?
I have my django/celery/sqs service ready for a set of calculations with one account. I would like to trigger calculations for many accounts. Currently, I am thinking two ways to do implement this: 1. upload accounts through a csv file, process these accounts and trigger the calculations one by one through rest api. 2. again, upload accounts through a csv file, but directly implement the service inside application, this might be a repeating work since I have the calculation for a single account already. Thanks for any suggestion. -
DRF Serializer sets provided field to None

optimizing Django REST Viewset with 1k+ queries for a single object
I have a ViewSet with nested serializers which is making over 1000 SQL queries and taking over 15 seconds to load a single object. I feel I must be doing something catastrophically wrong to get such horrendous performance, but I'm having trouble pinning it down. Similar posts recommend select_related() and prefetch_related(), but their use has brought my SQL query count from 1066 to 1062 -- not even a start.

How to instantiate a class one time and access it in views
I have a class that runs once, which I had in myapp/__init__.py, but each time django starts it would run twice. It also runs when I migrate models, when I don't need it to. I've read about the ready function https://docs.djangoproject.com/en/dev/ref/applications/#django.apps.AppConfig.ready, but cannot access the instantiated class outside of apps.py Here is my current workflow: in init.py: from .my_module import ResourceHeavyClass resource_heavy_instance = ResourceHeavyClass() in my views.py from . import resource_heavy_instance This currently works, but I only want to load the module when the server starts, not when I make migrations. Appreciate any tips/advice.
