How to convert "None" to null in custom permission in DRF?
I'm currently learning Django Rest Framework and currently stuck on a problem which is kind of impossible for me to figure out. I'm providing you an example, just to make the picture clearer. from rest_framework.exceptions import PermissionDenied from rest_framework.permissions import BasePermission class CheckAuthentication(BasePermission): def has_permission(self, request, view): authenticated = request.auth if not authenticated: raise PermissionDenied( { "exception_data": None } ) return True Ok So, in the above example I want to response to be like the following JSON { "exception_data": null } but instead of it, I'm getting { "exception_data": "None" } is there any way I can get the desired JSON ?? -

What is AH00489: resuming operations in apache?
When I restart the apache2 server I find some thing like this in log file: [mpm_event:notice] [pid 19078:tid 139998808778624] AH00489: Apache/2.4.18 (Ubuntu) mod_wsgi/4.3.0 Python/3.5.2 configured -- resuming normal operations Some part of that I understood is that it is resuming the required operatons since we restarted apache server. I'm not clear about: AH00489: Apache/2.4.18 (Ubuntu) mod_wsgi/4.3.0 Python/3.5.2 configured I'm using python3.6 as default and for my venv. I find 3.5.2 in above log. I doubt if this is causing me further issues like wsgi errors. Can some one tell me if I need to congigure it to python 3.6? If so, how should I change the configuration -

Django: a canconical method for a package to offer new template tags?
I'm building a package of Django extensions and one thing I'd like to include in it now are template tags (and filters). The question is, how does a package provide template tags to a Django project? I imagine in a Django app, in the templatetags directory adding a line to two to access them. Something like: from mypackage.template import tags say. Or if need actually running something to register them, possibly as built-in tags a la: https://djangosnippets.org/snippets/342/ from mypackage.template import register_tags register_tags() Before I experiment this to death (given I can't find any docs or example yet) I'm curious if there's a canonical approach to this as there are many Django extension packages. To be honest if I could reliably find one that provides template tags it could serve as an example of course. Any tips in this regard are appreciated. -

Django Admin Panel: Show/Hide Fields If Specific Value Is Selected In A Dropdown

Why is there time delay using asyncio in django
I'm trying to make a system that judges code(python files) in given time with asyncio. This is how it works: In judge.py, it calls processor.py and write the output to a text file. processor.py basically excutes the given python file and track the time the code used. judge.py import asyncio, time async def cmd(): try: proc = await asyncio.create_subprocess_shell( "processor.py > output.txt", shell=True, stdout=asyncio.subprocess.DEVNULL, stderr=asyncio.subprocess.DEVNULL) await proc.communicate() except asyncio.CancelledError: proc.terminate() print("X") PROCESS_TIME_BOUND = 5 acceptable_time = 0.1 async def run(): try: await asyncio.wait_for(cmd(), PROCESS_TIME_BOUND + acceptable_time) print("A") except asyncio.TimeoutError: print("B") loop = asyncio.ProactorEventLoop() asyncio.set_event_loop(loop) loop.run_until_complete(run()) As you can see. There's a line await asyncio.wait_for(cmd(), PROCESS_TIME_BOUND + acceptable_time) because the async function takes time to excute way longer than the time that the python file actually takes. In my computer, while the python file ends in 0.000001 seconds, the async function takes around 3.4 seconds. processor.py: import os, time, sys start = time.time() with open(sys.argv[1],'r') as f: exec(f.read()) end = time.time() print("PROCESS ENDED WITHTIN %.20f SECONDS" % (end-start)) Why and how does this time delay occur? Are there any ways to fix the time delay? Thanks in advance. -

Initial migrations after cloning repo - "related model cannot be resolved"
I'm working with a few people on an app. I'm doing front end. Recently, I've messed up migrations. After trying to fix them for a few hours, I've dropped all tables, and cloned the repo again. Since there are no migrations files, I run manage.py makemigrations (for some reason it does not detect all apps, just one of them, and I have to call makemigrations manually for each of them). Then, I run manage.py migrate. I get the following error: Related model 'User.user' cannot be resolved Since User table has OneToOneField relation to User table. Also, other tables depend on each other as well. My take on this problem would be commening out all the fields that cause the problem, making migrations, uncommenting them, and making migrations again. I guess this is far from optimal though. -
Required field issues when submitting Django formset
I'm having trouble with field validation in a Django formset derived from a model. Here are relevant models in my models.py: class Qualification(Data): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) amount_approved = models.PositiveIntegerField(blank=True, null=True) expiration_date = models.DateField(blank=True, null=True) class QualificationDocument(models.Model): qualification = models.ForeignKey(Qualification, on_delete=models.CASCADE, related_name='documents') file = models.FileField(upload_to='qualification_docs/%Y/%m') name = models.CharField(max_length=128) description = models.CharField(max_length=256, blank=True, null=True) upload_date = models.DateTimeField(auto_now_add=True) My views.py file includes this to present and process the a formset that allows the user to add one or more QualificationDocuments to the database: q = Qualification.objects.get(id=q_id) QualificationDocumentFormSet = forms.inlineformset_factory(Qualification, QualificationDocument, fields=('file', 'name', 'description'), widgets={ 'name': forms.TextInput(attrs={'placeholder': 'Name'}), 'description': forms.TextInput(attrs={'placeholder': 'Description'}) }, extra=1) if request.POST: formset = QualificationDocumentFormSet(request.POST, instance=q) if formset.is_valid(): formset.save() else: formset = QualificationDocumentFormSet(instance=q) # Render formset in Django template here And the template file includes this: <form id='upload-form-{{ q.id }}' method="post" action="{% url 'submit_and_refresh' %}"> {% csrf_token %} {{ formset.management_form }} <div id="form_set"> {% for f in formset.forms %} {{ f.non_field_errors }} {{ f.errors }} <div class="doc-form"> <div class="new-qual-doc-params"> {{ f.id }} {{ f.file }} {{ f.name }} {{ f.description }} </div> <div class="new-qual-doc-delete">{{ f.DELETE }}<small>Delete</small></div> </div> {% endfor %} </div> <button type="submit" class="btn btn-block">Save</button> </form> Two issues. No required fields. This template doesn't produce required tags in inputs like … -
Auto Increment Non-primary Key Field in Django with PostgreSQL
I've got an abstract base class from which many models inherit. It defines a field called order. I've built this into the system because I often need to order my objects in arbitrary ways (for listing in template, for example). However, I often find that the order fields get away from me and I lose track (I'm allowing null=True and blank=True). I'd like to have a way to ensure that whenever an object of model type with order is created, Django looks to other objects of the same type and checks the highest order number and increments accordingly. Is this possible? I've tried making the field order auto increment (with AutoField) but Django complains saying I've got an auto field already, the primary key. I'd use the primary key ID but this is assigned arbitrarily and doesn't maintain the order I want.
