Combine django mptt TreeNodeChoiceField with django-autocomplete-light ModelSelect2 widget
A django-mptt TreeNodeChoiceField gives indented select options, whereas I can filter my results using django-autocomplete-light. However, the ModelSelect2 widget overwrites the rendered html, which removes the indentation. I would like to combine the two. Any idea how I could achieve this? models.py: class Foo(MPTTModel): name = models.CharField(max_length=50) parent = TreeForeignKey('self', null=True, blank=True, related_name='children', db_index=True) class MPTTMeta: order_insertion_by = ['name'] forms.py: class FooForm(forms.ModelForm): parent = TreeNodeChoiceField(queryset=Foo.objects.all(), widget=autocomplete.ModelSelect2(url='foo-autocomplete')) class Meta: model = Foo fields = ('name', 'parent', ) -
Python: Model.objects.all() - how to iterate through it using POST checkboxes
I have been building a CSV export using Python/Django. While sending all items listed in the change list everything works like a charm. Now, I've been trying to use Action dropdown and export only those items selected via the checkboxes, but I cannot make it work. My current code, the one that works even with the Action dropdown yet exporting ALL items, regardless of what was checked: def export_this_list(self, request, queryset): """Generates participants list in Excel sheet.""" csv_elements = Enrolment.objects.all().order_by('-training__date') for elem in csv_elements: When csv_elements is swapped with request.POST.getlist obviously nothing works. def export_this_list(self, request, queryset): """Generates participants list in Excel sheet.""" csv_elements = request.POST.getlist('_selected_action') or csv_elements = [] for o in request.POST.getlist('_selected_action'): Question: what is the syntax to combine my Model with the POST action? -
IntegrityError with DateField - when creating objects with get_or_create
I'm having an issue with Django's get_or_create, when ever I create same objects with same dates integrity error pops up. I have field in my model as follows. class Cart(models.Model): created = models.DateTimeField( pgettext_lazy('Cart field', 'created'), auto_now_add=True) last_status_change = models.DateTimeField( pgettext_lazy('Cart field', 'last status change'), auto_now_add=True) user = models.ForeignKey( settings.AUTH_USER_MODEL, blank=True, null=True, related_name='carts', verbose_name=pgettext_lazy('Cart field', 'user')) email = models.EmailField( pgettext_lazy('Cart field', 'email'), blank=True, null=True) def add(self,hoarding, date_from, date_until): cart_line, created = self.lines.get_or_create( hoarding=hoarding,date_from=date_from,date_until=date_until) class CartLine(models.Model): cart = models.ForeignKey( Cart, related_name='lines', verbose_name=pgettext_lazy('Cart line field', 'cart')) hoarding = models.ForeignKey( Hoarding, related_name='+',blank=True, null=True, verbose_name=pgettext_lazy('Cart line field', 'hoarding')) date_from = models.DateField(blank=True, null=True, verbose_name=pgettext_lazy('Cart line field', 'from')) date_until = models.DateField(blank=True, null=True, verbose_name=pgettext_lazy('Cart line field', 'until')) error arises when i try to add same objects to cart with same from-date and until-date: IntegrityError at /hoardings/hoardings-demo-2-5/add/ UNIQUE constraint failed: cart_cartline.cart_id, cart_cartline.date_from, cart_cartline.date_until get_or_create will return an IntegrityError when creating objects with same dates.I added unique features in datefield but got the same error. I use Django 1.11 and Python 2.7 I reset database few times but it doesn`t help, db is Postgres/sqlite. -
Validate count() constraint in many to many relation before saving an instance in django
I would like to prevent a save in a django model when a certain constraint is not met and give a validation error so that a django staff user knows what went wrong. The constraint is the count() from an intermediate table specified using the through parameter. models.py: class Goal(models.Model): name = models.CharField(max_length=128) class UserProfile(models.Model): goals = models.ManyToManyField(Goal, through=UserProfileGoals, blank=True) class UserProfileGoal(models.Model): goal = models.ForeignKey(Goals) user_profile = models.ForeignKey(UserProfile) class UserGoalConstraint(models.Model): user_profile = models.OneToOneField(UserProfile) max_goals = models.PositiveIntegerField() So the UserGoalConstraint.max_goals gives me the number of the maximum definable UserProfile.goal which are stored in the UserProfileGoal model (same UserGoal can be stored more often to the UserProfile) I have read and tried solutions from several posts, which are using ModelForm's clean(), Model's clean() and pre_save signal events, but the actual problem I have is, how do I know if it is just an update or a new database entry, because class UserProfileGoal(models.Model): goal = models.ForeignKey(Goals) user_profile = models.ForeignKey(UserProfile) def clean(self): goal_counter = self.user_profile.goals.count() + 1 try: qs = UserGoalConstraint.objects.get(user_profile=self.user_profile) except UserGoalConstraint.DoesNotExist: raise ObjectDoesNotExist('Goal Constraint does not exist') if goal_counter > qs.max_goals: raise ValidationError('There are more goals than allowed goals') does not really work, as clean() can also be an update and the … -

Count rows of a subquery in Django 1.11
I have a couple models class Order(models.Model): user = models.ForeignKey(User) class Lot(models.Model): order = models.ForeignKey(Order) buyer = models.ForeignKey(User) What I'm trying to do is to annotate Lot objects with a number of buys made by a given user to the same seller. (it's not a mistake, Order.user is really a seller). Like “you’ve bought 4 items from this user recently”. The closest I get was recent_sold_lots = Lot.objects.filter( order__user_id=OuterRef('order__user_id'), status=Lot.STATUS_SOLD, buyer_id=self.user_id, date_sold__gte=now() - timedelta(hours=24), ) qs = Lot.objects.filter( status=Lot.STATUS_READY, date_ready__lte=now() - timedelta(seconds=self.lag) ).annotate(same_user_recent_buys=Count(Subquery(recent_sold_lots.values('id')))) But it fails when recent_sold_lots count is more than one: more than one row returned by a subquery used as an expression. .annotate(same_user_recent_buys=Subquery(recent_sold_lots.aggregate(Count('id'))) doesn't seem to work also: This queryset contains a reference to an outer query and may only be used in a subquery. .annotate(same_user_recent_buys=Subquery(recent_sold_lots.annotate(c=Count('id')).values('c')) is giving me Expression contains mixed types. You must set output_field.. If I add output_field=models.IntegerField() to the subquery call, it throws more than one row returned by a subquery used as an expression. I'm stuck with this one. I feel I'm close to the solution, but what am I missing here? -

How to use multiple settings files with sites framework in django
I am trying to setup multiple sites from a single project in django. I was trying to set this up following sites framework but there is no mention of how to use multiple settings files for all of the instances on the live server, it just said: In order to serve different sites in production, you’d create a separate settings file with each SITE_ID (perhaps importing from a common settings file to avoid duplicating shared settings) and then specify the appropriate DJANGO_SETTINGS_MODULE for each site. my wsgi.py : import os os.environ["DJANGO_SETTINGS_MODULE"] = "ProjectName.settings" #On the live server #os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings") #On the local host from django.core.wsgi import get_wsgi_application application = get_wsgi_application() this is my Settings files : ├── Site1_settings.py └── Site2_settings.py So, how wsgi will use the appropriate settings file for each instance when open it using this line os.environ["DJANGO_SETTINGS_MODULE"] = "ProjectName.settings" What am i missing to run it on the live server? thanks -

Django: how to poll a django application for updates? (noob edition)
I have a simple application in Django which consists of a form and a results page. After the form is submitted there is some processing which can take quite some time. Naturally, it would be nice would be to run the computation asynchronously to get the user to the results page faster provide updates for the user of the progress of their request. So I have tried figuring out how to do this and I can not figure it out. To my understanding I should do the following: install celery make an app in celery with a task to do the computation have that task output the progess either to a log file or update the model (if the model has a status field) use JS and JQuery or angular.js or node.js and socket.io to somehow poll my application for this progress. and from there whatever else I am told or I can find either glosses over how this works, assumes I know how this works and can adapt it to my use case, or if they try to explain it, I just dont understand. I made a demo project. In this demo project we have two views index and … -

Django channels - update active connections
I have setup channels to update connected mobile app users. I have a Group model that owns users and also IoT sensors. If the authenticated user is connected an is in a Group, any sensor update in that group will be sent to those users. If add a user to a group after he has connected to the server, he wont get any updates in the new group until he connects again. Should they reconnect once the groups are updated? Or how should this be done? Then second question - if the user lost connectivity and in that time a message was sent to the group. How could I ensure that the users who connected late does also get the messages? Im thinking I should create a table that keeps a log of users and messages. I would like to follow the best practice for both these questions! Thanks! -

Here is my HTML: <!DOCTYPE html> {% load staticfiles %} <html lang="en-us" ng-app="myApp"> <head> <title>Voting App</title> <meta http-equiv="X-UA-Compatible" content="IE=Edge"> <meta charset="UTF-8"> <!-- load bootstrap and fontawesome via CDN --> <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" /> <link rel="stylesheet" href="{% static "css/styles.css" %}" /> </head> <body> <header> <nav class="navbar navbar-default"> <div class="container"> <div class="navbar-header"> <a class="navbar-brand" href="/">G2 Crowd Team Roster</a> </div> </div> </nav> </header> {% verbatim %} <div class="container"> <div ng-controller="mainController"> <div class="row" ng-cloak ng-repeat="person in data"> <div class="col-xs-12 col-sm-5 col-md-3"> <img ng-src="{{person.image_url}}"/> </div> <div class="col-xs-12 col-sm-7 col-md-9"> <h2>{{ person.name }}</h2> <h3>{{ person.title }}</h3> <p>{{ person.bio }}</p> <h4>Want to work with {{ person.name }}? <a href="" ng-click="add_vote()"><img src="../static/svg/thumbs-up.svg">Yes!</a></h4> <h5><b>{{ vote }}</b> people have said Yes!</h5> </div> </div> </div> </div> {% endverbatim %} <script src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script> <!-- Latest compiled and minified JavaScript --> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script> <!-- Load angular via CDN --> … -

How to send data from multiple blocks to backend in Django?
My current template structure contains 2 blocks, "page_content" and "sidebar". There is an html-form with "POST" method in "page_content" block that sends data to backend, but the problem is that this form is working with mobile-size screen only, and for the desktop there is a second block - "sidebar".
