Getting 'ERR_TOO_MANY_REDIRECTS' error when using custom Middleware in Django
I am trying to use a custom Middleware to restrict page access when the user is not authenticated.

How to trigger AJAX request without POST request in Django?Rather initiate onClick
So I am new in here , currently working on a Django project. So I was facing an Issue. Let me give a detailed description of the problem: So I have a model called Music: class Music(models.Model): musicid = models.AutoField(primary_key=True) title = models.CharField(max_length=200) # category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='category') audio = models.FileField(upload_to='music/') published_at = models.DateTimeField(default=datetime.now , blank=True) def __str__(self): return str(self.musicid) View File is as follows def index(request): songs = Music.objects.all() context = { 'title':'Home', 'songs':songs, } return render(request , 'index.html',context) So now in my html i render all my music which i am storing in my local DB. They can be easily fetched via the getting the url of audio file.Now I made a common Player for all my songs. Here comes the real ISSUE. Suppose I have 10 songs , and I click any one of them , how do I send an AJAX request with the specific music id so that I can render the audio url for that specific song. <audio id="music" class="current-track" > <source src="{{songs.audio.url}}" type="audio/mpeg"> </audio> here songs is the queryset of the specific song id. I am using AJAX as it's clearly evident I dont want the page to redirect to somewhere else … -

Alternative method of using slug in newer versions of django
I have been following along the Try django 1.10 URL Shortening Playlist (CodingEntrepreneur) and I am fairly new at django. In the 20th video of the series, they used slug regex with URLs, however when I tried the same, it threw an error, and someone has commented that slug doesn't work with "paths". Can someone please help me with finding the alternative to it? -

Elastic-beanstalk build pre-deploy and run command post-deploy
I am new to Elastic-beanstalk. I tried using CLI but got little confused. I have a typescript project which has to build first and then dist folders contents need to be deployed. Currently I manually build and compress dist folder into zip file and then upload. Also, there is a command to run from production enviroment which I currently do by switch all my enviroment and then manually migrate. I know there is some thing called extentions or config file. Please guide me to automate the above process with those extentions. # pre-deploy yarn build # generated file in dist folder # deployed the folder # post-deploy # in production enviroment npm run migrate -
Django CRC Calculator?
Trying to build an endpoint that takes an input string, polynomial and initial value and outputs a CRC value. Everything I've found so far only support existing algorithms and do not take additional inputs. I finally found one that takes all kinds of inputs (pycrc) but it seems to only do so via CLI. How would I go about incorporating pycrc into Django? Thanks! -
How to rewrite this postgres constraint to be more in line with django 2.2?
THis is the raw query that I write for postgres for the check constraint ALTER TABLE rea_asplinkage ADD CONSTRAINT asp_sub_project_positive_integer CHECK ( jsonb_typeof(linkage-> 'root' -> 'in_sub_project') is not distinct from 'number' and (linkage->'root'->>'in_sub_project')::numeric % 1 = 0 and (linkage->'root'->>'in_sub_project')::numeric > 0 ); And the way I create the migration is this way # Generated by Django 2.2.10 on 2020-05-16 12:59 from django.db import connection, migrations class Migration(migrations.Migration): dependencies = [("rea", "0029_asplinkage")] operations = [ migrations.RunSQL( sql=""" ALTER TABLE rea_asplinkage ADD CONSTRAINT asp_sub_project_positive_integer CHECK ( jsonb_typeof(linkage-> 'root' -> 'in_sub_project') is not distinct from 'number' and (linkage->'root'->>'in_sub_project')::numeric % 1 = 0 and (linkage->'root'->>'in_sub_project')::numeric > 0 ); """, reverse_sql=""" ALTER TABLE rea_asplinkage DROP CONSTRAINT "asp_sub_project_positive_integer"; """, ) ] And this works.

For reference, I have looked at the examples found in https://github.com/django/django/blob/master/tests/constraints/models.py#L12 I have also looked at Separate Database and State migration via https://realpython.com/create-django-index-without-downtime/#when-django-generates-a-new-migration But I still cannot get it to work So … -
SSL Problem with GAE App Engine w/o custom domain/SSL certificate

In Django what is the right way of adding form field from another form in a formset?
I've got some nested formsets within a formset and I'd like to flatten it but I'm struggling with creating the fields. So far I have the below; class BaseHostFormset(BaseModelFormSet): def add_fields(self, form, index): super(BaseHostFormset, self).add_fields(form, index) form.nested = VLanInlineFormset(instance=form.instance, data=form.data if form.is_bound else None, files=form.files if form.is_bound else None, prefix='Vlan-%s-%s' % ( form.prefix, VLanInlineFormset.get_default_prefix())) for nested_form in form.nested.forms: for field in nested_form: if field.name is not None and nested_form['vlan_name'].value() is not None: field_name = nested_form['vlan_name'].value() + "_" + field.name form.fields[field_name] = nested_form[field.name] but when I iterate over the form I get; AttributeError: 'BoundField' object has no attribute 'get_bound_field' Which makes sense I think as the add_fields method is expecting a forms.CharField object but I want to keep the attirbutes from the other forms fields. What would be the right way to do this? -
Django TestCase not creating/deleting model instances
I'm having a few problems when running some of my tests. For instance say I have a view # view.py class DeleteAccount(DeleteView) model = User ... As expected, when I send a valid post request, the given User object is deleted. However, when I make this request from a test, the User object is not deleted: # tests.py class DeleteAccountTest(TestCase): def test_delete_user(self): email = 'test@email.com' user = User.objects.create_user(email=email) response = self.client.post(reverse('delete_account', args=[email])) self.assertEqual(response.status_code, 302) delete_user = User.objects.filter(email=email) self.assertFalse(delete_user.exists()) This final assertion fails as the deleted user is still in the db. Since this works outside of tests, I am assuming there is something going on behind the scenes that I am not seeing. I am getting the same problem when creating Model objects in views too. An explanation to what I'm doing wrong would be greatly appreciated. Thanks -

Django - Reload model definition runtime - metaclass
I'm writing a model class based on EAV paradigm. The implementation is based on python metaclass that is responsible to "create" the model interface so all django features (admin, forms, class base views,...) can work without any further changes. The model definition (fields list and related type) is done using the admin interface. What I'm not able to do is to reload the model on save event after any changes is made in the admin interface. It's clear that the solution is very useful only if I can do the model changes without the need of restart the engine. Is there a way to force the model reload for a django model without restarting the engine? -

Hosting a django app on a subpath using Nginx
The django app is being run using Gunicorn at 10.0.11.12:8199 My Nginx config is as follows, I'm forced to use location since the app is being hosted on some sort of a shared hosting service (https://www.feralhosting.com/). They give us access to servername.feralhosting.com/myusername where we can install software and access them using servername.feralhosting.com/myusername/softwarename location /softwarename { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_x_host; proxy_set_header X-NginX-Proxy true; rewrite /(.*) /myusername/$1 break; proxy_pass http://10.0.11.12:8199/; proxy_redirect off; } When I visit servername.feralhosting.com/myusername/softwarename or a route like servername.feralhosting.com/myusername/softwarename/admin I get the 404 Django page saying the URL wasn't found. Django itself seems to work fine only the URL mapping seems to be causing issues. An example of a path in my main urls.py file is path('softwarename/admin/', admin.site.urls) all paths are similarly configured. Thanks for any help in advance. -
how to ensure that only one data record is valid at a time - Django Rest Framework

Analyzing log files according to timestamp in django
I'm trying to make an API for analyzing log files. The API will take a list of log files ("logFiles" -> array of strings) and count of parallel file processing ("parallelFileProcessingCount" -> integer) as input and outputs the number of exceptions grouped by time range and exception type. At any moment "parallelFileProcessingCount" files should be processed simultaneously if more than "parallelFileProcessingCount" files are remaining. If processing for any file is finished then the next file should be picked immediately for processing, so that "parallelFileProcessingCount" files are being processed at every moment, if more than "parallelFileProcessingCount" files are remaining. The format of the log file is as follows:- 586763334343 1523718907817 NullPointerException 586763434443 1523718907818 IllegalAgrumentsException where 1st string is the request-id, 2nd string is a timestamp (in UTC) and the 3rd string is the Exception Name. It can be assumed that all the files are for a single day and entries in files are sorted by time (in UTC). The 15 min range will start from the start of the day (00:00), until the end of the day(24:00), so there will be 96-time ranges. Example: Input: { "logFiles": ["https://example.file/log1.txt"], "parallelFileProcessingCount": 1 } Output: 21:15-21:30 IllegalAgrumentsException 1,21:15-21:30 NullPointerException 2, 22:00-22:15 UserNotFoundException 1,22:15-22:30 ....... -
