Django Query set is empty on chosen.js multiselect... Why?
I'm going to simplify my problem by focusing on one example I have the following javascript that determines which chosen multiselect option will be shown based on another select option. Everything is working correctly with the JS. For my problem i'm only going to show the group option selected. $(document).ready(function () { $('#accesslevelid').change(function () { $this = $(this) $('.content_box').each(function () { $select = $('select', this); if ($select.data('id') == $this.val()) { $(this).show(); $select.show().chosen(); } else { $(this).hide(); $('select', this).hide(); } }); }); }); Inside my form I have the following: {% block extra_js %} {{ block.super }} {{ form.media }} <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.js" type="text/javascript"></script> <script src= "{% static '/accounts/chosen.jquery.js' %}" type="text/javascript"></script> <link rel="stylesheet" href="{% static '/accounts/chosen.css' %}"> <div id = "div_groupdimselect" class="content_box"> <select data-placeholder="Choose a group..." data-id="4" class="chosen-select" multiple tabindex="4" id = "id_groupdimselect" value = "{{facility.blevel}}" style="width: 1110px"> {% for facility in facilitydim %} <option value="{{facility.group_name}}">{{facility.group_name}}</option> {% endfor %} </select> </div> With my view I'm attempting to access the users chosen selection with the following, the datareducecode works when i filter on the users coid, but when i try datareducecode1 it returns and empty set: grouplist = request.POST.getlist('blevel') if request.method == 'POST' and selectedaccesslevel == '4': datareducecode = OrgLevel.objects.filter(coid__exact = owner.coid).values_list('blevel', flat … -

Django data leak between 2 separated tests
In my whole tests base, I experience a weird behaviour with two tests. They are completely isolated. However, I can find data from the first test in the second one. Here are the tests: file1 (services.tests) class ServiceTestCase(TestCase): @patch('categories.models.ArticlesByCategory.objects.has_dish_type') def test_build_dishtype_conflicts(self, mock_has_dish_type): # WARN: create interference in tests restaurant = RestaurantFactory() dt_1 = DishTypeFactory(restaurant=restaurant) cat_1 = CategoryFactory(restaurant=restaurant) art_1 = ArticleFactory(name='fooA1', restaurant=restaurant) art_2 = ArticleFactory(name='fooA2', restaurant=restaurant) abc_1 = ArticlesByCategory.objects.create(category=cat_1, article=art_1, is_permanent=True, dish_type=dt_1) abc_2 = ArticlesByCategory.objects.create(category=cat_1, article=art_2, is_permanent=True, dish_type=dt_1) mock_has_dish_type.return_value = [abc_1, abc_2] abcs_to_check = ArticlesByCategory.objects.filter(pk__in=[abc_1.pk, abc_2.pk]) conflicts = ServiceFactory()._build_dishtype_conflicts(abcs_to_check) self.assertDictEqual(conflicts, {dt_1.pk: 2}) file2 (products.tests) class ArticleQuerySetTestCase(TestCase): def test_queryset_usable_for_category(self): restaurant = RestaurantFactory() category_1 = CategoryFactory(name='fooB1', restaurant=restaurant) category_2 = CategoryFactory(name='fooB2', restaurant=restaurant) article_1 = ArticleFactory(restaurant=restaurant) article_2 = ArticleFactory(restaurant=restaurant) ArticlesByCategory.objects.create(article=article_1, category=category_1, is_permanent=True) queryset_1 = Article.objects.usable_for_category(category_1) # This line is used for debug for art in Article.objects.all(): print(art.name) When running test_build_dishtype_conflicts THEN test_queryset_usable_for_category in the same command, here are the results of the print in the second test: fooA1 fooA2 fooB1 fooB2 I suspect I did something wrong but can't find what. -
Django widget tweaks' render_field not working
I have this form rendering template in django, and render_field is not working inside if-else: {% load widget_tweaks %} {% for field in form %} <div class="form-group"> {{ field.label_tag }} {% if form.is_bound %} {% if field.errors %} {% render_field field class="form-control is-invalid" %} {% for error in field.errors %} <div class="invalid-feedback"> {{error}} </div> {% endfor %} {% else %} {% render_field field class="form-control is-valid" %} {% endif %} {% else %} {% render_field field class="form-control" %} {% endif %} {% if field.help_text %} <small class="form-text text-muted"> {{ field.help_text }} </small> {% endif %} </div> {% endfor %} And it renders this: But when I try a smaller version of the above code like following, then also it still doesn't work: {% load widget_tweaks %} {% for field in form %} <div class="form-group"> {% if field.errors %} {% render_field field class="form-control is-invalid" %} {% else %} {% render_field field class="form-control is-valid" %} {% endif %} {% if field.help_text %} <small class="form-text text-muted"> {{ field.help_text }} </small> {% endif %} </div> {% endfor %} And renders this: But when I remove all if-else's: {% load widget_tweaks %} {% for field in form %} <div class="form-group"> {{ field.label_tag }} {% render_field field … -
Build system for aws
I was using a free tier aws account in which I had one ec2 machine (Linux). I have a simple website with backend server running on django at 8000 port and front end server written in angular and running on http (80) port. I used nginx for https and redirection of calls to backend and frontend server. Now for backend build system, I did these 3 main steps (which I automated by running jenkins on the same machine). 1) git pull (Pull the latest code from repo). 2) Do migrations (Updating my db with any new table). 3) Restarting the django server. (I was using gunicorn). Now, I split my front end and backend server into 2 different machines using auto scaling groups and I am now using ELB (Aws Elastic Load balancer) to route the requests. I am done with the setup. But now I am having problem in continuous deployment. The main thing is that ELB uses auto scaling groups which in turn uses AMI. Now, since AMI's are created once, my first question is how to automate this process and deploy my latest code in already running aws servers. Second, if I want to run few steps … -
how to apply multiple query on multiple queryset in django
I wrote a query which is fetching some details toll_obj = Toll.objects.filter(driver__profile__invoice_number=(invoice_number)) Here toll_obj can be multiple queryset, one field is common for all objects in qs(toll_obj) that is form_date. So I want to apply one more condition here which is form_date<=today . So what can be the best way to achieve this. Any help would be appreciated. -
Django app not working on mobile only (desktop is fine)?
I'm running a Django app on a private intranet which requires either the company wifi to access or, alternatively, a VPN connection in order to open it from a non-company wifi channel. That's working as intended. The issue is that I can access the site from mobile (iPhone, iPad) when I'm on the company wifi. But when I'm connected through public wifi, even if I'm connected via VPN and I can access the intranet, I cannot access the site. For a variety of security reasons I can't disclose precise details or code, so I'm not looking for an explicit solution. Instead, I would be very, very grateful for some general ideas as to what might possibly be causing this, or things that I could start looking into and/or check. I know this isn't your typical stack overflow post, but it is definitely useful for me and I believe helpful to anybody else who runs into a similar issue if we can create a list of possible reasons for this error. -
Using Sass with Django
Im looking for a reasonably simple toolset and workflow for incorporating Sass into my Django projects. Im predominantly backend focused and have just started investigating Sass, so bear with me. My initial idea was to keep things simple by just using node-sass without trying to incorporate Gulp, django-pipeline or anything else initially. My Django apps are usually structured such that I create a static/app/css folder in each app. One option I guess would be to now create an additional folder per app for scss files, ie: static/app/scss. Next, outside of my Django project folders I would create a folder to install node-sass since I wouldn't want to install it globally and I don't want the node-modules folder inside my Django project or inside source control. I guess the node-modules folder can be thought of like using a python virtualenv instead of installing packages globally? Next, inside my Django project somewhere (not sure where?) I would have the package.json file containing a scripts section for every scss file I want compiled to css, eg: "scripts": { "compile:sass": "node-sass app1/static/app1/scss/style.scss app1/static/app1/css/style.css", "compile:sass": "node-sass app2/static/app2/scss/style.scss app2/static/app2/css/style.css", "compile:sass": "node-sass app3/static/app3/scss/style.scss app3/static/app3/css/style.css" } Lastly, I would just run compile:sass with the watch flag to constantly … -
Celery should return a non-zero exit code an exception occurs
I'm experiencing a weird situation with Celery 4.1, Python 2.7.13. When there is an issue with the connection between Python app and Database (MySQL in this case), Celery does not return a non-zero code and keep the worker running which doesn't make any sense. Although I can see the exception in the result of celery -A myapp worker -l INFO -E but the worker doesn't stop. I tried almost all options of celery worker but no luck. Is there any way to force the worker to stop working and exit if the database connection is failing? -
Trigger bootstrap modal after django form submission
How can I trigger the bootstrap modal to popup after my django form was submitted? In my index.html template I have a standard looking modal like this <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> ... </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> below in the same index.html I have a django form {{ form.non_field_errors }} {% csrf_token %} <ul id="robul"> <div class="form-group"> <div class="col-xs-6"> <li id="name" name="{{ form.name.name }}" class="form-control">{{ form.name }}</li> </div> </div> <div class="form-group"> <div class="col-xs-6"> <li id="email" class="form-control">{{ form.email }}</li> </div> </div> <div class="form-group"> <div class="col-xs-6"> <li id="contactmessage" class="form-control">{{ form.contactmessage }}</li> </div> </div> </ul> in my view.py it looks like this: if request.method == 'POST': form = forms.FormName(request.POST) if form.is_valid(): contact_name = request.POST.get( 'name', '') contact_email = request.POST.get( 'email', '') form_content = request.POST.get('contactmessage', '') template = get_template('contact_template.txt') context = {'name': contact_name, 'email': contact_email, 'contactmessage': form_content,} content = template.render(context) mail = EmailMessage("New contact form submission", content, "Some Name" +'', ['somegmail@gmail.com'], headers = {'Reply-To': "noreply@gmail.com" }) mail.send() return render(request, 'index.html', {'form': form}) -
Django (v2.0.1) form Creation and pulling data's from DB
I am learner and started using django framework for a small project. I am struggling to create a form and pulling values from the DB. I have a table "travel" in my DB which has the following fields in it. ID, customer_name, travel_date, billing_status, created_at, updated_at 1, Robin Hood, 2018-01-10, Paid, 2018-01-10 15:29:25, 2018-01-10 15:29:25 Now I wanted to have a form with the above fields which should pull all the records from the database "travelmanager" and table "travel". If someone could, provide me an example with the above details. That could be very very helpful. Thank you in advance. -
Combine two querysets from different models into one queryset
I need to combine two querysets into one queryset (the result can't be a list or other type of object) as when I iterate on the querysets in a template I need to access their relations, which cannot be done from a list or dictionary. I've tried solutions like union however this is unacceptable as I need access to the relations in the template. The loop that I need the data structure for looks like the loop below. The two relations on this object are user and aircraft. {% for key in active %} <tr> <td>{{key.user.name}}</td> <td>{{key.aircraft.tail_number}}</td> <td>{{key.departure_date}}</td> <td>{{key.departure_city|title}}</td> <td>{{key.arrival_city|title}}</td> </tr> {% endfor %} One idea is to somehow do a join between the two tables in a way that a queryset is returned however at this point I've been unable to figure out how to do that. I haven't tried raw SQL yet so maybe that's the route? -
Add a field to a model in the view
I would like to add the field unread to a chat model in the view. The field unread needs to be computed first and depends on another model called chatmessages. Right now unread can only be requested separately from a chat via detail_route: class ChatViewset(ModelViewSet): ... @detail_route(methods=['get'], ) def unread(self, request, pk): chat = self.get_object() assert isinstance(chat, Chat) all_messages = ChatMessage.objects.filter( Q(in_chat__first_participant=request.user, in_chat__blocked_by_first_participant=False) | Q(in_chat__second_participant=request.user, in_chat__blocked_by_second_participant=False), in_chat=chat) all_unread_messages = all_messages.filter( Q(in_chat__first_participant=request.user, sent_by_first_participant=False, read_by_receiver=False) | Q(~Q(in_chat__first_participant=request.user), sent_by_first_participant=True, read_by_receiver=False)) return Response({'unread': all_unread_messages.count()}) def list(self, request, *args, **kwargs): self.serializer_class = ChatSerializer return super(ChatViewset, self).list(request, *args, **kwargs) def retrieve(self, request, *args, **kwargs): self.serializer_class = ChatSerializer return super(ChatViewset, self).retrieve(request, *args, **kwargs) ... How could I integrate unread into the view of chat? -

Redirect the output of custom Django command to the browser
I have created a custom command which takes a positional and a named optional argument. It does many checks, downloads a file, unzips it and populates the database with the unzipped data. To make the things more convenient for the users I created a simple form and created a view: from django.views.generic.edit import FormView from django.core import management from .forms import DownloadForm class DownloadFormView(FormView): template_name = 'frontend/download.html' form_class = DownloadForm success_url = '.' def form_valid(self, form): country = form.cleaned_data['country'][:3] levels = int(form.cleaned_data['country'][-1:]) management.call_command('download_shapefile', country, levels=levels) return super(DownloadView, self).form_valid(form) That works fine and now I want to provide feedback to the user, as the command might run for a while. Is there any possibility to redirect the command output (or make it available) to the template and display it in the browser? In my command I use: self.stdout.write(self.style.SUCCESS('some success message')) self.stdout.write(self.style.WARNING('some warning message')) to output messages and don't print directly with the print method. -

Is it possible to have django apps in their own docker container and manage/interact with them?
Is it possible to have each app in a django project in its own docker container? this way 1- All the dependencies of the app is contained to itself and there wont be any dependency conflicts between two apps. 2- In our project we are discussing a use case where apps should deployed in containers(primary and backup) such that when the primary goes down the backup takes over .. basically implementing High availability(HA) of an app. I know that this may not exactly be a use case that Django was built to solve, but if it is doable in Django then i would like to do it using django as we have already created lot of apps using django and changing the architecture for the sake of HA would be a lot of work. Note: I understand that the whole project can be deployed in a container and HA can be implemented.. but i'm more interested distributing apps in containers. -
Gunicorn queue wait time
My setup is nginx => gunicorn => django. I am using gunicorn with sync workers. Can I find out how long requests take till they find an available gunicorn worker? I will use this measure to find out if I have too little workers and thus increase the count, does that make sense? I have the RAM available, as currently I am only using 50% of it, but if they aren't queued up I will use the RAM for something else. Can I somehow tell nginx or gunicorn master to annotate the wait time in queue?
