Django/Plotly - Click events with JS
I'm able to simply display my plot (3D scatter) using Plotly. I'm trying to implement a click event feature. Once I click at any of the plot point I'd like to change its color. According to official Plotly documentation it's not that hard: Plotly - click event All I can see is that the points I click are being clicked (console logs). Does anyone got some clue why I'm not able to the change the color in a real time ? Thanks in advance. Here's my snippets: Template: {% extends 'base.html' %} {% load static %} {% block css %} <script src="{% static 'js/plotly-latest.min.js' %}"></script> {% endblock %} {% block content %} <div id="single_plot"> {{ plot_as_div|safe }} </div> {% endblock %} {% block js %} <script src="{% static 'js/plot_select_markers.js' %}"></script> {% endblock %} plot_select_markers.js $(document).ready(function () { var plot_div_id = $('#single_plot').children().attr('id'); var plotly_scatter_div = document.getElementById(plot_div_id); var color_select = '#7b3294'; plotly_scatter_div.on('plotly_click', function (data) { var pn = '', tn = '', colors = []; for (var i = 0; i < data.points.length; i++) { pn = data.points[i].pointNumber; tn = data.points[i].curveNumber; colors = data.points[i].data.marker.color; } colors[pn] = color_select; var update = { 'marker': { color: colors, size: 7 } }; Plotly.restyle(plotly_scatter_div, update, … -
explanation for in loop Python/Django [duplicate]
This question already has an answer here: Python for-in loop preceded by a variable 4 answers I'm following the official tutorial on Django and i came across this lines def index(request): latest_question_list = Question.objects.order_by('-pub_date')[:5] output = ', '.join([q.question_text for q in latest_question_list]) return HttpResponse(output) It's everything clear except for the for in loop and i can't find anywhere where to understand how it is written. Why q.question_text is BEFORE the for in loop? I already looked at the other question questioning this line of code, but i cannot fine anywhere some python documentation that explain me how the syntax of this loop works, even though i can understand what it does. Also i'm new to python and i am clearly miss something... -
Django Disable/Exclude Field in CreateView but enable/include it in UpdateView
I would like to exclude/disable a Charfield (with options and a default value) when creating a new object, but when editing this object, I would like to enable / include the Charfield for the user to change it. So far I tried this answer I found here on Stackoverflow, but it wasn't the full solution for me. The Charfield did get disabled but when I tried to create my object, Django would always tell me that the field is required (even though it has a Default Value). My code: class OfferCreateForm(forms.ModelForm): class Meta: model = Offer exclude = ['date', 'number'] def __init__(self, *args, **kwargs): request = kwargs.pop("request", None) super(OfferCreateForm, self).__init__(*args, **kwargs) instance = getattr(self, 'instance', None) if instance and instance.pk: self.fields['status'].widget.attrs['disabled'] = False else: self.fields['status'].widget.attrs['disabled'] = True self.helper = FormHelper() self.helper.form_tag = False self.helper.help_text_inline = True self.helper.add_layout(Layout( Fieldset('Angebot', Row( Div( Field('name'), css_class='col-sm-12' ), Div( Field('category'), css_class='col-sm-6' ), Div( Field('status'), css_class='col-sm-6' ), )), Fieldset('Kunde', Row( Div( Field('customer', css_class='selectize'), css_class='col-sm-6' ), Div( Field('receiver', css_class='selectize'), css_class='col-sm-6' ), )), Fieldset('Kundeninformation', Row( Div( Field('introduction'), css_class='col-sm-12' ), ), ), Fieldset('Zusätzliche Informationen', Row( Div( Field('footer'), css_class='col-sm-12', ), ), ), )) def clean_status(self): instance = getattr(self, 'instance', None) if instance and instance.pk: return instance.status else: return self.cleaned_data['status'] The … -

Django & Celery: Do I need transaction.atomic/locking in order to avoid race-conditions?
Users in my app can import data fetched from an API into my Django database. The API uses paging if there are > 100 results to fetch. I obviously don't want the users to wait to for a possibly big number of items to import. So I'm doing the first call to the API in the request, and then delegating the rest to Celery. > User requests an API item with 250 items > Fetch 100 and return > Fetch 150 more in a celery task I'm worried database corruption. I'm running my app on Heroku with the following configuration in the Procfile: web: daphne app.asgi:channel_layer --port $PORT --bind 0.0.0.0 -v2 worker: python manage.py migrate --noinput && python manage.py runworker -v2 celerybeat: celery -A app beat -l info celeryworker: celery -A app worker -l info And I call the task like so: if rginitial_count >= 100: continue_doing_imports.delay(artist_mbid=self.mbid, artist_name=self.name, offset=100) How can I insure consistent behavior? for example, user A is importing data for Artist X, and at the same time user B attempts to subscribe to that same artist, therefore needing to write to his relationships? that's one scenario I can think of. -
Disabling Django Silk for specific URLs
I have an API endpoint on which I can upload a photo using a multipart request. When Silk is trying to parse the request, I get a decoding error. I now want to disable Silk for certain URL endpoints.

How to display values of object for which check box is ticked?
In my django project, there is an object named Point. It is defined like this in models.py : class Point(models.Model): name = models.CharField(max_length = 30, unique = True) # name of the point x = models.IntegerField(default = 1) # x coordinate of point y = models.IntegerField(default = 2) # y coordinate of point z = models.IntegerField(default = 3) # z coordinate of point def __str__(self): return self.name+":("+str(self.x)+","+str(self.y)+","+str(self.z)+")" I want to make an interface which shows all the points with check boxes which can used to display and update points information. It looks like this: This is my code in views.py: def update_here(request): """ Used to update any coordinates of any point. """ points_list = Point.objects.all() if request.method == 'POST': x1 = request.POST['x_value'] y1 = request.POST['y_value'] z1 = request.POST['z_value'] point = Point.objects.get(name = "Vizag") point.x = x1 point.y = y1 point.z = z1 point.save() return redirect('update_here') return render(request,'update_here.html',{'points_list_in_html':points_list}) And my html code I've written till now (I am to display the values in boxes when checkbox of a point is ticked) in update_here.html: <html> <head> <title>Update here</title> <script type="text/javascript"> var helper = { numb : function(numberOfBlanks,xx,yy,zz){ var checked=0; var j=0; var k; for(j=0; j<numberOfBlanks.length; j++){ if(numberOfBlanks[i].checked){ break; } } return j; … -
Django aggregation taking a lot of time

What's the most popular web server or architecture?
I heard some companies use Django only and some use Ruby on Rails and some use Django/RubyOnRails + Java backend (the web server forward all the requests to the Java back server to retrieve data and doing business logic). So, which is the preferred way of hosting a web application? And what are the reasons behind this? -

Keep in mind that the Highcharts.Chart constructor and all features of Highcharts are included in Highstock, so if you are running Chart and StockChart in combination, you only need to load the highstock.js file" Thank you -

Custom schema for class-based view in django rest framework for Sagger
I have the following problem. There are a couple of non-model view in my module. So for them I need to write schema explicitly. I came around two solutions fro this problem: Create a special api_schema_generator() with schema description def api_schema_generator(): api_schema = coreapi.Document( title="Market", content = { "User Adresses": { "int_api_get": coreapi.Link( url="/v1/market/calendar/biz_day/", action="get", description="Get the next buisness day", fields=[ coreapi.Field( name = "region_id", required=True, location="path", description="Unique region ID" ), coreapi.Field( name="base_date", required=False, location="path", description="Unique region ID" ), ] ) } } ) But the main disadvantage of this approach is that there are some views that can be generated automatically, cause they have module serializer. Moreover, I think it is better to describe class schema within class-view. So, the second solution is something like that: class BizDay(GenericAPIView): schema = ManualSchema(fields=[ coreapi.Field( name="region_id", required=True, location="path", description="Unique region ID" ), coreapi.Field( name="base_date", required=False, location="path", description="Unique region ID" ), ]) serializer_class = BizDayReq def get(self, request, version): serializer = BizDayReq(data=request.query_params) serializer.is_valid(True) data = serializer.validated_data regions = data['regions'] base_region = regions[0] days_offset = data['days_offset'] cutoff_region = data['cutoff_region'] cutoff_hour = data['cutoff_hour'] calendar = TradingCalendar(*regions) if data.get('base_date'): dt_now = convert.timestamp_to_datetime(data['base_date'], base_region) else: dt_now = convert.get_current_datetime(base_region) cutoff_dt = convert.get_current_datetime(cutoff_region) cutoff_dt = cutoff_dt.replace(hour=cutoff_hour, minute=0, second=0, microsecond=0) … -

Django - Redirect to a subclass admin page
I'm creating a web application with Django. In my models.py I have a class BaseProduct and a class DetailProduct, which extends BaseProduct. In my admin.py I have BaseProductAdmin class and DetailProductAdmin class, which extends BaseProductAdmin. I have another class called Channel, with a many to many relation with BaseProduct.
