djnago celery flower socket error: address already in use
In order to debug hanging workers of celery I installed flower on both my development and production server. On development it is installed correctly and I can access flower dashboard using port 5555. On production after installation when I try to start flower server by doing celery flower error came which says socket.error: [Errno 98] Address already in use. To debug I tried to see what is running on port 5555 in both development and production. On development without celery flower server running, nothing returns. On development with celery flower server running following comes: which seems fine. On production server without celery flower server running following comes: This is quite confusing as even though I haven't run celery flower, its process is already running and I am not able to access the dashboard. -

How to Implement linked zooming, panning in bokeh plots when embedded as Components
I have a django web application where we render multiple bokeh plots (timeseries) for usability it is required that the x-axis of all plots is linked between all plots (time). I had the following solution (pseudocode) that worked with bokeh-1.10.0 plot_1 = figure() plot_1.line([0,1,2],[1,2,3]) plot_2 = figure() plot_2.line([0,1,2],[1,3,9]) plot2.x_range = plot_1.x_range # This line causes the linking script1, div1 = components(plot_1) script2, div2 = components(plot_2) Then the div1, div2 and the scripts were embedded into a django template. Bokeh-js did the magic so when plot_1 is zoomed plot_2 is zoomed simultaneously. Since the x_range objects have the same id. But with bokeh-0.12.1 it seems that bokeh js the second plot is not effected by the zooming events on the first plot and vice versa. How can i achieve linked panning and zooming in a similar embedding setup? -
Change Django Rest Framework serializers output structure?
I have a Django model like this: class Sections(models.Model): section_id = models.CharField(max_length=127, null=True, blank=True) title = models.CharField(max_length=255) description = models.TextField(null=True, blank=True) class Risk(models.Model): title = models.CharField(max_length=256, null=False, blank=False) section = models.ForeignKey(Sections, related_name='risks') class Actions(models.Model): title = models.CharField(max_length=256, null=False, blank=False) section = models.ForeignKey(Sections, related_name='actions') And serializers like that : class RiskSerializer(serializers.ModelSerializer): class Meta: model = Risk fields = ('id', 'title',) class ActionsSerializer(serializers.ModelSerializer): class Meta: model = Actions fields = ('id', 'title',) class RiskActionPerSectionsSerializer(serializers.ModelSerializer): risks = RiskSerializer(many=True, read_only=True) actions = ActionsSerializer(many=True, read_only=True) class Meta: model = Sections fields = ('section_id', 'risks', 'actions') depth = 1 def to_representation(self, instance): response_dict = dict() response_dict[instance.section_id] = { 'actions': HealthCoachingActionsSerializer(instance.actions.all(), many=True).data, 'risks': HealthCoachingRiskSerializer(instance.risks.all(), many=True).data } return response_dict When accessing the RiskActionPerSectionSerializer over a view, I get the following output: [ { "section 1": { "risks": [], "actions": [] } }, { "section 2": { "risks": [], "actions": [] } }, ..... ] It s fine but I would prefer to have that : [ "section 1": { "risks": [], "actions": [] }, "section 2": { "risks": [], "actions": [] } ..... ] Also why is it returning an array by default [] and not an object for example like: { "count": 0, "next": null, "previous": null, … -
The view showname.views.delete didn't return an HttpResponse object. It returned None instead
I have the next code in delete generic class: class delete(DeleteView): def get(self, request, *args, **kwargs): def get_absolute_url(self): return reverse('index') There is the url patttern: url(r'^$', views.indext.as_view(), name='index'), As i understand from the decumentation, if i want to redirect thr user to the index when he tryies to approach the page through the url by himself, i Call "get" which defind what to do when "get" messege sent, and then "get_absolute_url" with "reverse" to do the same method that "url" in html pages does. But it doesnt work. why it returning None as the page sayes? -

How to display modal from bootstrap by checking cookie in javascript

Django Celery Periodic Task ignoring contrab
After an update it appears celery has stopped to work like it should. I have periodic tasks per day and from 6-22. All of the tasks running from 6-22 run every 5 minutes for no reason. I changed the task from running every hour to running from 6-22. The every hour function wasn't working either. I tried: minute=0 hour=6-22, minute=0, hour='*/3,8-17' and completely written like below. The last one i copied from the docs because i thought maybe this would work. @periodic_task( run_every=(crontab(minute=0, hour='6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22')), queue='feed', name="feed_update", ignore_result=True ) def feed_update(): """ checks for feed updates """ feed_update_for_all_users() logger.info("Feed Update complete") According to the Docs these are all valid contrab vars.
