Django: Setting attr on choices in CheckboxSelectMultiple widget
I have a field that I am trying to add data to each choice within my Form class. Form Class: class SubmissionAcceptForm(forms.Form): """ Form for individually accepting submissions. """ submissions = forms.ModelMultipleChoiceField( queryset=Submission.objects.all(), required=False, widget=forms.CheckboxSelectMultiple) def __init__(self, *args, **kwargs): submission_choices = kwargs.pop("submission_choices") super().__init__(*args, **kwargs) self.fields["submissions"].queryset = submission_choices self.fields["submissions"].initial = [ submission.pk for submission in submission_choices.filter(status='accepted')] self.fields["submissions"].widget.attrs['avg_score'] = [submission.avg_score for submission in submission_choices] self.helper = FormHelper() self.helper.layout = Layout( 'submissions', HTML("""<hr>"""), ButtonHolder( Submit('submit', 'Submit', css_class='btn btn-primary') ) ) Problem self.fields["submissions"].widget.attrs['avg_score'] = [submission.avg_score for submission in submission_choices] That line loops over the the submission scores, and renders all of the scores as an avg_score attr on every choice with all of the scores. <input avg-score="[Decimal('5.00'), Decimal('4.67'), Decimal('4.33'), Decimal('4.00'))]"> Example: if there are 4 choices, then all 4 scores are set as an avg_score attr on each choice.

django field select and text entry problem
I want to allow the user to expand (add additonal text in the same field) on the selected option for a django model field. I have a working select option field on the form but it does not allow addition or exapnsion of the selected item. This is as expected. In the real world i want to add some information to the option selected. Can this be done? class MedicalForm(forms.ModelForm): OPTIONS = ( ("COLD", "Common cold"), ("FLU", "Flu strain"), ("VIRUS", "Unknown virus"), ) illness = forms.CharField(max_length=60, label='What is wrong?', widget=forms.(choices=OPTIONS)) I would like the user to describe the symptoms for example after selecting the option. I allow 60 chars for the illness field. -

grid lines with for loop
so I want to have three grid lines, such that <div class="col-6 col-md-4"> each grid line has a content of course. so the code will probably tell what I'm trying to achieve <div class="row"> <div class="col-6 col-md-4"> {% for all_episode in episode %} <div class="card"> <a href="{% url 'episode_detail' slug=all_episode.slug %}"><img class="card-img-top" src='{{all_episode.image.url}}'></a> <div class="card-body"> <h5 class="card-title"> <a href="{% url 'episode_detail' slug=all_episode.slug %}">{{ all_episode.title }}</a> </h5> <p class="card-text">{{ all_episode.story |slice:":100" }}...</p> </div> <div class="card-footer"> <small class="text-muted"> <span class="h5"> <a href="{% url 'series_detail' slug=all_episode.series.slug %}">{{ all_episode.series }}</a> </span> / <span class="h6"><a href="{% url 'season_detail' slug=all_episode.season.slug %}">{{ all_episode.season }}</a></span></small> </div> {% endfor %} </div> </div> </div> but with the above code i get the cards in align vertically. so one card takes the whole line while there should be three cards. -
Sum of related objects across 2 FK to the same table, with conditions
I have two models: class User(Model): ... class Message(Model): sender = ForeignKey(User, CASCADE, 'sent_msgs') receiver = ForeignKey(User, CASCADE, 'rcvd_msgs') ignored = BooleanField() I'm trying to annotate a queryset of Users with a sum total of their related messages, i.e. sum of both sent_msgs and rcvd_msgs. Additionally, any Message with ignored=True should be ignored. I can do this with RawSQL fairly simply, using a subquery: SELECT COUNT("messages_message"."id") FROM "messages_message" WHERE "messages_message"."ignored" = FALSE AND ( "messages_message"."sender_id" = "users_user"."id" OR "messages_message"."receiver_id" = "users_user"."id" ) queryset = queryset.annotate(msgs_count=RawSQL(that_query_above)) Is there a way to do this without using RawSQL? -

How to handle a join of a variable number of incoming?
Is there a way to handle "partial Joins" in viewflow? For example: an order is received, and after checking and booking-in then each line item is manufactured in parallel (Split). Normally these would all join before the customer required-by date, and then the order will be dispatched with everything in one shipment. But sometimes there is an unexpected hold on one or more items because of a manufacturing issue that could not be known at the time the order is accepted. Is there a way to describe a "join" of the items that are ready for shipment to be joined into a partial shipment, and leaving the other manufacturing tasks to complete in however long it takes and be joined into another shipment later? Or is this too complex for viewflow, and should I be looking at several separate business processes? One process to book in an order which starts N manufacturing processes, and then code run by Celery to pick out completed manufacturing which needs to be dispatched, either because everything for that order is ready, or because the order requires partial shipment. I'm still teaching myself viewflow and working through the cookbook examples (and also Celery) so apologies … -
How to build a Serializer for a Normalized DataBase
Maybe my question has already been answered, but I could not find anything. Lets say that Im building a stock inventory system using Django + Django REST for the backend. To supply this I have this two models: class Shoe(models.Model): _id = models.AutoField(primary_key=True) description = models.CharField(null=False, blank = False) provider = models.CharField(null=False, blank=False) category = models.CharField(choices=CATEGORIES, null=False, blank=False) class Sizes(models.Model): shoe_id = models.ForeignKey(Shoe, on_delete=models.CASCADE) size = models.IntegerField(choices=SIZE_LIST, null=False, blank=False) amount = models.IntegerField(null=False,default=0) My doubt is, how can I (using ModelViewSet, cause based on my experience with DRF is the easiest way) serve JSON files like this: [ { "_id": "1", "description": "Air Max Black", "provider": "NIKE", "category": "Casual", "available_sizes": {36: 400, 37: 250}, #size: amount "amount": "650" #total amount }, ] Based on what I understand of DRF to "join" the two models in a JSON I should write a custom serializer right? Usually my serializers are like class FooSerializer(serializers.ModelSerializer): class Meta: model = Foo fields = ['some_stuff_here'] Please help me or recomend me reading material for do that, I have read the DRF docs about Serializers but cant understand how to do stuff like this. -

How to give read/write permissions to dynamic sub-directory?
I have a FileNotFoundError after deployment when I run one of my python processes on the web server.

With Django, how can I ensure manage commands use a different logging configuration?
Scenario I want to ensure (guarantee) that all manage command invocations generate logs to a custom location, based on the name; e.g. the command appends to a file named for the command: $ bin/django changepassword ... $ ls /var/log/django/changepassword.log $ bin/django shell $ ls /var/log/django/shell.log Options I have a custom logging configuration which I'm registering in settings.py, but that's not the place I'd expect to get such custom behavior. Monkey patch something? But what, and where? -

Action decorators kwargs not passed on when retrieving the view with "as_view" method on a ViewSet
In one app, I have the following ViewSet: class MyViewSet(MyGenericViewSet, ListModelMixin): queryset = MyModel.objects.all() serializer_class = MyModelSerializer @action(detail=False, methods=["post"], accepted_renderers=(MyJsonRenderer,)) def custom_action(request, *args, **kwargs): # Do some stuff here MyViewSet is routed with a DefaultRouter. I need to specify MyJsonRenderer because it comes second in my DEFAULT_RENDERERS setting (I have an HTML renderer first) and this particular action is not meant to be used with a web browser. It works fine when I hit the routed URL with a POST request, and always returns JSON content. However I also need to adapt my site to an old AJAX API, so in another adapter app, I have the following function-based view: @csrf_exempt def ajax(request, *args, **kwargs): custom_action_view = MyViewSet.as_view({"post": "custom_action"}) return custom_action_view(request, *args, **kwargs) If my request does not specify that it is expecting JSON content in its header or params, content negotiation fails because the default HTML renderer is used (500 Internal Server Error). The action is performed on the server but the response is not rendered. How can I make the view obtained with as_view to use the proper renderer class ? -

How to integrate the bokeh server INTERACTIVITY with django?
I already know how to display standalone bokeh plots on Django. What I'm looking for now is a high-level explanation on how to connect the interactive bokeh server (the sample I'm using is https://demo.bokeh.org/weather) to my Django project. The key word here to stress is interactive. When I use the dropdowns on my Django page the Bokeh server should respond interactively as it normally does when I run bokeh serve --show app.py for example. As you can see below, I've already thrown most of the tutorial's code into my django view. It all displays perfectly, however there's no interactivity happening - when I select to view Seattle's data, for example, nothing happens - because the bokeh server isn't being activated or something? # all my imports up here... def homepage(request): return render(request, 'pages/landing.html') def alerts_dashboard(request): # !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! # THE FOLLOWING CODE FROM HERE ON DOWN IS PURE COPY-PASTED FROM # THE BOKEH DEMO LINK ABOVE STATISTICS = ['record_min_temp', 'actual_min_temp', 'average_min_temp', 'average_max_temp', 'actual_max_temp', 'record_max_temp'] def get_dataset(src, name, distribution): df = src[src.airport == name].copy() del df['airport'] df['date'] = pd.to_datetime(df.date) # timedelta here instead of pd.DateOffset to avoid pandas bug < 0.18 (Pandas issue #11925) df['left'] = df.date - datetime.timedelta(days=0.5) df['right'] = df.date … -

Попробуйте позже') } }) }) }) </script> urls from django.conf.urls import url from products.views import ( Categories, ProductsOrderStatus, ProductsOrderCancel, Products, ProductsCreate, ProductsDetail, ProductsUpdate, ProductsDelete, ProductsCopy, ProductsReport, JointProducts, JointProductsCreate, JointProductsDetail, JointProductsUpdate, JointProductsDelete, JointProductsCopy, JointProductsReport, add_to_cart_view, orders_week_view, orders_month_view, orders_year_view, bills_week_view, bills_month_view, bills_year_view, basket_view, cart_true_view, remove_cart_view, BillDetail, privat24 ) urlpatterns = [ url(r'^(?P<section_slug>products|joint_products)/$', Categories.as_view(), name='products_categories_list'), url(r'^(?P<section_slug>products|joint_products)/orders/(?P<pk>[\d]+)/status/$', ProductsOrderStatus.as_view(), name='products_order_status'), url(r'^(?P<section_slug>products|joint_products)/orders/(?P<pk>[\d]+)/cancel/$', ProductsOrderCancel.as_view(), name='products_order_cancel'), url(r'^products/add/$', ProductsCreate.as_view(), name='products_create'), url(r'^products/(?P<slug>[-\w]+)/add/$', ProductsCreate.as_view(), name='products_create'), url(r'^products/(?P<slug>[-\w]+)/$', Products.as_view(), name='products_list'), url(r'^products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/$', ProductsDetail.as_view(), name='products_detail'), url(r'^products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/update/$', ProductsUpdate.as_view(), name='products_update'), url(r'^products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/delete/$', ProductsDelete.as_view(), name='products_delete'), url(r'^products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/copy/$', ProductsCopy.as_view(), name='products_copy'), url(r'^products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/report/$', ProductsReport.as_view(), name='products_report'), url(r'^joint_products/(?P<slug>[a-zA-Z0-9-][^_]+)/add/$', JointProductsCreate.as_view(), name='joint_products_create'), url(r'^joint_products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/$', JointProductsDetail.as_view(), name='joint_products_detail'), url(r'^joint_products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/update/$', JointProductsUpdate.as_view(), name='joint_products_update'), url(r'^joint_products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/delete/$', JointProductsDelete.as_view(), name='joint_products_delete'), url(r'^joint_products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/copy/$', JointProductsCopy.as_view(), name='joint_products_copy'), url(r'^joint_products/(?P<pk>[\d]+)/(?P<slug>[-\w]+)/report/$', JointProductsReport.as_view(), name='joint_products_report'), url(r'^joint_products/(?P<slug>[a-zA-Z0-9-][^_]+)/$', JointProducts.as_view(), name='joint_products_list'), url(r'^add_to_cart/$', add_to_cart_view, name='add_to_cart'), url(r'^remove_cart/$', remove_cart_view, name='remove_cart'), url(r'^orders_week/$', orders_week_view, name='orders_week'), url(r'^orders_month/$', orders_month_view, name='orders_month'), url(r'^orders_year/$', orders_year_view, …
