Cannot render chartit-django chart example
Im trying to build a dashboard in django framework using chartit. But the documentation seems to be for advanced people. Im a beginner trying to learn, so sorry. Im having a problem that i can render the chart in my dashboard. What i really dont understand in the docu was this, <!-- code to include the highcharts and jQuery libraries goes here --> <!-- load_charts filter takes a comma-separated list of id's where --> <!-- the charts need to be rendered to --> {% load chartit %} {{ weatherchart|load_charts:"container" }} i really dont understand those comments. What to put. Where to put it. Im rendering the chart to an extended html so i really dont know where to put it. Sorry im just a beginner im still learning. This is my base html {% load staticfiles %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Dashboard - Dark Admin</title> <link rel="stylesheet" type="text/css" href="{% static 'bootstrap/css/bootstrap.min.css' %}" /> <link rel="stylesheet" type="text/css" href="{% static 'font-awesome/css/font-awesome.min.css' %}" /> <link rel="stylesheet" type="text/css" href="{% static 'css/local.css' %}" /> <script type="text/javascript" src="{% static 'js/jquery-1.10.2.min.js' %}"></script> {% load chartit %} <script type="text/javascript" src="{% static 'bootstrap/js/bootstrap.min.js' %}"></script> <!-- you need to include the shieldui css … -
Django form ImageField
I'm trying to establish CreateView for the model which holds ImageField. I can successfully upload and display images from django admin page. But, when I upload images from my own form, django doesn't upload images to "upload_to" folder. I'm writing my codes below: models.py from django.db import models class Album(models.Model): title = models.CharField(max_length=127) artist = models.CharField(max_length=63) release_date = models.DateField() logo = models.ImageField(blank=True, upload_to='album_logos', default='album_logos/no-image.jpg') def __str__(self): return self.title forms.py from django import forms from .models import Album class AlbumCreateForm(forms.ModelForm): class Meta: model = Album fields = [ 'title', 'artist', 'release_date', 'logo' ] views.py class AlbumCreateView(CreateView): form_class = AlbumCreateForm template_name = 'music/album_create.html' success_url = '/albums/' album_create.html {% extends 'base.html' %} {% block content %} <form method="post">{% csrf_token %} {{ form.as_p }} <button type="submit">Create</button> </form> {% endblock %} When I try to create album using "album_create.html" and upload image with django's default form, logo image isn't uploaded to "album_logos" folder and takes default value. Where am I doing wrong? -
Django: deleting a one-to-one related field in post_delete causes recursion
I have a model, say Model1 that has a OneToOne related field Model2. There is a post_delete signal connected method of Model1 that calls instance.model2.delete(), and very infrequently, this causes a recursive call back to the Model1.post_delete(). I've followed the stack trace, here is the recursion on Django 1.8 (most recent last): File "myapp/models.py", line 645, in post_delete instance.model2.delete() File "django/db/models/base.py", line 896, in delete collector.delete() File "django/db/models/deletion.py", line 314, in delete sender=model, instance=obj, using=self.using File "django/dispatch/dispatcher.py", line 189, in send response = receiver(signal=self, sender=sender, **named) File "myapp/models.py", line 645, in post_delete instance.model2.delete() File "django/db/models/base.py", line 896, in delete collector.delete() File "django/db/models/deletion.py", line 314, in delete sender=model, instance=obj, using=self.using File "django/dispatch/dispatcher.py", line 189, in send response = receiver(signal=self, sender=sender, **named) After following it many times in debug, and testing extensively with automation, I have come to the conclusion that the problem is that File "django/dispatch/dispatcher.py", line 189, in send response = receiver(signal=self, sender=sender, **named) is erroneously being called from File "django/db/models/deletion.py", line 314, in delete sender=model, instance=obj, using=self.using somehow. What could possibly be going on? -
error in template rendering django and bootstrap
I am using a bootstrap index file in the header.html in a django project. Can anyone point out a fix or the easiest method to link the bootstrap file to the static folder. In what places does it need to be done, and how? Also, for use of bootstrap, could I just use the index file rather than header? I can see the error (below) but do not know the syntax to fix it. The route i've tried is using Jinja logic and it is on that line that the first error arises. (line 14) Current error: Error during template rendering In template C:\Users\User\Desktop\pythonsite\mysite\aboutme\templates\aboutme\header.html, error at line 14 Invalid block tag on line 14: 'static'.

Django show unique together fields in one model in another model's template

I got to the part where I could render Model Form but couldn't figure out the linking part. Will be very grateful for any advice from the experts here. -
django collectstatic with template processor
Is it possible to use templates for static files? I would like django could process the static files with template processor before copying them in the static folder when manage collectstatic is issued. Of course the context would not contain request information but it could be useful to use such information as: urls from url names to be used in javascript code settings to be used to customize css or static html pages What is the simpler way to accomplish this? -
PostgreSQL with Django: transaction is aborted error
I have PostgreSQL and Django 1.8. When I try to create an MyModel object via Django ORM, I get InternalError current transaction is aborted, commands ignored until end of transaction block. My code look like: MyModel.objects.get_or_create(client=client, defaults={ 'email': client.user.email, 'name': client.name, 'phone_number': '77644017513' }) But when I modify MyModel via psql (I tried to delete a record) everything is just fine. When I try to create object from another model (not MyModel) everything is fine too. What is wrong with MyModel? -
POST request not behaving as intended
I've been trying to get my button to send a POST request to the submitted URL, which does a write back to the database. The application looks like the POST request gets sent, but after hitting the button my URL never changes and the print at the submitted URL appears to be an empty set.

Django URLs file error
I have the following urls.py file in a Django project, and I am getting an error which I assume is relating to the latest syntax relating to urls and paths. The code I have in the urls file which is url.py in the mysite (outermost directory) is: from django.urls import path from django.conf.urls import url, include urlpatterns = [ path(r'^$', include('aboutme.urls')), ] The error message is: Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: ^$ The empty path didn't match any of these. In the actual app (website folder) which is called 'aboutme', the urls.py file looks like this: from django.urls import path from django.conf.urls import url, include from .import views #this is the main thing we are going to be doing ....returning views! urlpatterns = [ path(r'^$', views.index,name='index'), ] Can anyone shed any light on the correct syntax or what I am doing wrong? -
Celery tasks are not always getting executed in the right order
I have several periodic tasks that run every few minutes/hours along with many more event-driven tasks. Sometimes an event-driven task will be received by a worker that is already busy executing one of the longer periodic tasks, and then the event-driven task will not run until the longer periodic task is completed. I checked using celery flower, and there ARE available workers, so I don't understand why the busy worker claimed the task. I would like the event-driven task to go to an available worker. I have a machine with 16 workers and celery beat running. I am running Celery 4.1.0 with Django 1.8.16. I am also using Redis as my broker. Here are the commands used to start all the celery workers: celery beat -A proj & celery multi start 16 -A proj -l info -c1 -Ofair -

Avoid concurrent access to same queue element
I'm reviewing/refactoring a queue that's going to be used internally by up to 20 people simultaneously but as of now, multiple people can access the first element ( We tried it locally clicking on the link at the same time. ) The flux is similar to this: views.py [GET] def list_operator(request, id): if request.POST: utilitary = Utilitary(id) pool = ThreadPool(processes=1) async_result = pool.apply_async(utilitary.recover_people, (id, )) return_val = async_result.get() person = People.objects.get(pk=return_val) return redirect('people:people_update', person.pk) utilitary.py This file has the method recover_people which performs around 4-5 queries (where people have flag_allocated=False) across multiple tables and sorts a list, to return the first element. The final step is this one: for person in people: p_address = People_Address.objects.get(person_id=person.id) p_schedule = Schedules.objects.get(schedules_state=p_address.p_state) if datetime.now() > parse_time(p_schedule.schedules_hour): person = People.objects.get(pk=person.id) person.flag_allocated = True person.date_of_allocation = datetime.now() person.save() return person.pk Perhaps something in the Utilitary method's logic is wrong? Or I should be expecting this problem with this amount of people simultaneously calling this method? Could using a cache help? I'm sorry, I'm new to django and mvc. -
