Difference between usage of Django celery and Django cron-jobs?
I am sorry if its basics but I did not find any answers on the Internet comparing these two technologies. How should I decide when to use which as both can be used to schedule and process periodic tasks. This is what an article says: Django-celery : Jobs are essential part of any application that does some processing for you in the background. If your job is real time Django application celery can be used. Django-cronjobs : django-cronjobs can be used to schedule periodic_task which is a valid job. django-cronjobs is a simple Django app that runs registered cron jobs via a management command. can anyone explain me the difference between when should I choose which one and Why? Also I need to know why celery is used when the computing is distributed and why not cron jobs -
Access files in production-mode of django project
For my Django project I have to open an xsl-file that is permanently located on the server to perform some actions on other files that the users can upload. In development mode I just used a relative path in the python script to point to that xsl-file and it worked fine: xslFile = open('./transform.xsl') However, as I am now in the stage of deploying the project to the server, I am having troubles with changing that line of code so that the file can still be found in production mode. I already tried setting an absolute path like xslFile = open('/srv/www/htdocs/djangoProject/mysite/transform.xsl') which threw errors. Furthermore I tried moving the file to the static directory which I state in my settings.py: STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static/') and tried then to open the file like this: from django.conf import settings xslFile = open(os.path.join(settings.STATIC_ROOT, 'transform.xsl')) However, both of these tries produce error messages of this kind: FileNotFoundError at /mysite/add/ [Errno 2] No such file or directory: 'transform.xsl' Request Method: POST Request URL: xx.xx.xx.xxx/mysite/add/ Django Version: 2.2.7 Exception Type: FileNotFoundError Exception Value: [Errno 2] No such file or directory: 'transform.xsl' Exception Location: /srv/www/htdocs/djangoProject/mysite/createDatabase.py in handleInputFiles, line 84 Python Executable: /usr/bin/python3 Python Version: … -
Can't add comment form in Django web application
I have a trouble adding form-group (I believe it's bootstrap class). The form-group doesn't do anything at all, or maybe it's a problem with form.author and form-body variables!? More simply, I need UI comment section (now only I can add and edit comments from django admin page). Some code: post_details.html <article class="media content-section"> <form action="/post/{{ post.slug }}/" method="post"> {% csrf_token %} <div class="form-group"> {{ form.author }} </div> <div class="form-group"> {{ form.body }} </div> <button type="submit" class="btn btn-primary">Submit</button> </form> <ul> {% for comment in post.comments.all %} <p> <b>@{{ comment.author }}</b> <small>{{ comment.created_date }} </small> </p> <p> {{ comment.text }}</p> <hr> {% if comment.replies.all %} <ul> {% for reply in comment.replies.all %} <p>{{ reply.text }}</p> <hr> {% endfor %} </ul> {% endif %} {% endfor %} <ul> </article> forms.py from django import forms class CommentForm(forms.Form): author = forms.CharField( max_length=60, widget=forms.TextInput( attrs={"class": "form-control", "placeholder": "Your Name"} ), ) body = forms.CharField( widget=forms.Textarea( attrs={"class": "form-control", "placeholder": "Leave a comment!"} ) ) views.py def comment(request): form = CommentForm() if request.method == "POST": form = CommentForm(request.POST) if form.is_valid(): comment = Comment( author=form.cleaned_data["author"], body=form.cleaned_data["body"], post=post, ) comment.save() context = {"post": post, "comments": comments, "form": form} if request.method == 'POST': form = CommentForm(request.POST) if form.is_valid(): comment = Comment( … -
Struggling to pass request.user.id to SQL function in python/django
hoping someone can help as I'm new django (and coding) and I'm stuck with trying to pass the current user's ID number to an SQL function. I've spent days searching for a solution but nothing I've tried has worked. I know the SQL function works as I can pass through a number without any issue, but when trying to use request.user it just comes up blank. views.py: def my_custom_sql(request): current_user = User.objects.get(request.user) with connection.cursor() as cursor: cursor.execute("SELECT first_name FROM customuser WHERE id = %s",[current_user]) row = cursor.fetchone() return row def dashboard(request): return render(request, 'dashboard.html', {'my_custom_sql': my_custom_sql}) models.py: class CustomUser(AbstractUser): pass # add additional fields in here employee_dob = models.DateField(blank=True, null=True) is_executive = models.IntegerField(blank=True, null=True) def __str__(self): return self.username dashboard.html: <a href="{% url 'home' %}">Home</a> <br> {% if user.is_authenticated %} <p>Is this the your first name?: {{my_custom_sql}}</p> {% else %} <p>You are not logged in, please do so.</p> {% endif %} I've read everything I can find around the issue but haven't found anything yet that has helped. I'm not sure if it has something to do with sessions or django hashing the info? But I'm not sure how to get around this safely. Anyone got any idea how to resolve … -
How to plug in a specific validator for all cases of a built-in type?
I recently noticed that some of my entries in a database coming from users contain incorrectly encoded strings, such as ó when ó was clearly meant. It's coming from copy-pasting of other websites that aren't properly encoded, which is beyond my control. I discovered that I can add this validator to catch such cases and raise an exception - here's an example with an attached model: from django.db import models from django.utils.translation import gettext_lazy as _ from django.core.exceptions import ValidationError import ftfy def validate_ftfy(value): value_ftfy = ftfy.ftfy(value) if value_ftfy != value: raise ValidationError( _('Potential UTF-8 encoding error: %(value)r' ' decoded to %(value_ftfy)r.'), params={'value': value, 'value_ftfy': value_ftfy} ) class Message(models.Model): content = models.CharField(max_length=1000, validators=[validate_ftfy]) def save(self, *args, **kwargs): self.full_clean() return super(Message, self).save(*args, **kwargs) The problem is that now that I discovered it, I see no point skipping it in any of my instances of CharField, TextField and the like. Is there a way to plug in this validator to all data types, so that if anything non-binary has invalid UTF-8, I can count on it not making it to the database? -
How to transfer data from a callback to another view in Django?
I have a function that makes a request to Erlang. Next, the Erlang sends a response to the url callback. I need this data in the original function to verify the success of the operation. Accordingly, the original function must wait until an answer arrives.

MAYAN-EDMS reviews and capabilities
I am currently working on a project to convert my organization away from manual file systems. We have a fairly narrow set of requirements for a document management system, and it appears that something open source like Mayan may be suitable for our needs. What I've not been able to discern from the documentation / website is whether the software system is capable of dealing with large numbers of documents and clients on a network. Our document count is in the neighborhood of 100 billions documents, and we have a dedicated scanning department (approx 1000 users) and a client-consumer base of about 6000 users. Some initial questions: Whether the Mayan is capable of dealing with large (100 Bn) numbers of documents. Will Mayan work at an enterprise level with the user and document base I've described? Can Mayan use MS SQL, or is it PostegreSQL / MySQL only? What would a file/data migration to Mayan look like? Is there any articles / documents that could help me jump into the code base? I've been doing quite a bit of Python work lately, and would be very interested in seeing how your system works under-the-hood. Please suggest any other open source … -

How to add minutes to datetime in postgres via django
TL;DR: I want to add minutes to a datetime in postgres and can think of two ways to do it. Consider the following django model: from django.db import models class AppointmentManager(models.Manager): def get_queryset(self): return super().get_queryset().annotate( end=models.ExpressionWrapper( models.F('start') + models.F('duration'), output_field=models.DateTimeField(), ) ) class Appointment(models.Model): start = models.DateTimeField() duration = models.DurationField() objects = AppointmentManager() Note that end is computed dynamically in the database by adding start and duration. This does exactly what I want. However, I want the UI for the duration to be a number input that gives the duration in minutes. My current approach is to use the following form field: import datetime from django import forms class MinutesField(forms.DurationField): widget = forms.NumberInput def prepare_value(self, value): if isinstance(value, datetime.timedelta): return int(value.total_seconds() / 60) return value def to_python(self, value): if value in self.empty_values: return None if isinstance(value, datetime.timedelta): return value if isinstance(value, str): value = int(value, 10) return datetime.timedelta(seconds=value * 60) This looks a little brittle to me. Is it also possible to store the duration as integer and transform it to a duration dynamically? -
Core compute for solid returned an output multiple times

Django - Existing DB Views and Foreign Keys
I have a simple view on the DB which select info from other DB's located on the same MSSQL Server to ultimately serve the info as a dropdown to the user. So far I've added the Model with inspectdb: class AutPricePlanView(models.Model): priceplan_name = models.CharField(db_column='PricePlan', max_length=50, blank=True, unique=True) class Meta: managed = False # Created from a view. Don't remove. db_table = 'AUT_PricePlanView' Also I have a second existing (Django Native) Model where I want to use the values from the view for a Dropdown Field (to keep everything in sync): class PricePlanDownload(models.Model): requesting_user = models.CharField(blank=True, default=None, max_length=50, null=True) requested_at = models.DateTimeField(auto_now_add=True) document = models.FileField(upload_to='documents/price_plan_uploads/%Y/%m/%d', blank=True) priceplan = models.ForeignKey(AutPricePlanView, null=True, on_delete=models.DO_NOTHING)``` Makemigrations works fine but when I try to actually migrate I get the following issue: (shortened it a little bit) *django.db.utils.ProgrammingError: ('42000', "[42000] [FreeTDS][SQL Server]Foreign key references object 'AUT_PricePlanView' which is not a user table.
