Fill the db with fake data
def _create_sources(fake, source_number): obj_list = [ Source( name=fake.sentence(nb_words=10, variable_nb_words=True), url=fake.url(), isbn_10=fake.isbn10(), isbn_13=fake.isbn13(), ) for _ in range(source_number) ] counter = 0 for obj in obj_list: Source.objects.bulk_create([obj]) print("{} {}".format(Source._meta.object_name, str(counter))) counter +=1 I fill my database with fake data. It is necessary for both debugging and even for development. By the way, it has nothing to do with tests. Initially I did: Source.objects.bulk_create(ob_list) It worked. But it the computer kept silence for a long time. And I decided to print a notification. My code is clumsy: I bulk_create just one object,having converted it into a list. Could you help me find a more elegant solution? -
Submitting a form in Django
I'm following a tutorial on youtube to create a Netflix clone. When I clicked the create profile button, the form data was cleared, but it didn't redirect me to the ProfileList page. Does it mean that the form is not valid?

Django model filter based on boolean field
I have a user model which has fields like these, is_active = models.BooleanField() date_joined = models.DateTimeField(auto_now_add=True) resigned_date = models.DateTimeField(blank=True, null=True) Where resigned_date will be None if is_active field is True. If is_active field is False then the resigned_date field will have the date. I think I can explain it. What I want is to queryset of users based on some DATE and is_active field. More clearly I want to get the list of employee that (is active and joined_date is less that or equal to the current date) and (is not active and resigned_date is greater that the current date) The query I have written so far: users = user_models.User.objects.filter( Q( is_active=True, date_joined__month__lte=month, date_joined__year__lte=year, ) & Q( is_active=False, resigned_date__month__gt=month, resigned_date__year__gt=year, ) ) But this is not working. It is not returning any users. How can I achive this? Thanks -

What exactly are path converters in Django
I am new to Django and I can't seem to wrap my head around what exactly a path converter does. As I understand, for each app we require a URLConf file, which will map our URL's to our view functions. In this way, when a URL is requested by a user, the corresponding view function will be executed. According to the documentation: Path converters¶ The following path converters are available by default: str - Matches any non-empty string, excluding the path separator, '/'. This is the default if a converter isn’t included in the expression. int - Matches zero or any positive integer. Returns an int. slug - Matches any slug string consisting of ASCII letters or numbers, plus the hyphen and underscore characters. For example, building-your-1st-django-site. uuid - Matches a formatted UUID. To prevent multiple URLs from mapping to the same page, dashes must be included and letters must be lowercase. For example, 075194d3-6885-417e-a8a8-6c931e272f00. Returns a UUID instance. path - Matches any non-empty string, including the path separator, '/'. This allows you to match against a complete URL path rather than a segment of a URL path as with str. So, does this mean, that the path converter acts … -
Migrations reflect not only database but some business logic. Migrations blow up

It will complain like 0002_migration contains user_directory_path, it is absent. This change in the code not mechanical. I can't imagine that it can be done just by refactor / rename in IDE. Then I can't imagine what the new migration should look like. This means that I will not be able to modify migrations file easily. I will have to deploy another project next to this one and another database. Delete all migrations, makemigrations, copy created migration and substitute all occurrances of user_directory_path with what is in my clipboard. Complicated, … -

I have a use case, where I am tracking the changes of a field. My issue is I want to trigger it even if there is no change in that field. E.g., status field changes from Null -> IM -> OK -> OK I have put my logging code based on the change of status field and due to some constraint I had to do the status change from IM to OK. I now want to trigger the tracker for the OK - > OK (the very first occurrence only) This is my post_save signal: @receiver(post_save, sender="iot_app.VehicleNumber") def vehiclenumber_post_save(sender, instance, created, *args, **kwargs): if changed == 'status': if created: continue try: log_ota_events.delay( vehicle_id=instance.id, event=getattr(instance, '_event_type'), source=getattr(instance, '_event_source', None), source_id=getattr(instance, '_event_source_id', None), metadata={ 'immobilize_status': instance.status, 'immobilizer_action': instance.immobilizer_action, 'immobilisation_valid_upto': str(instance.immobilisation_valid_upto), }, comment=getattr(instance, '_event_comment', None), ) except Exception as e: logger.warning(f"Couldn't log the event {e}", exc_info=True)``` -

jquery each function for auto generated html elements with same class
I have an ajax script that should act on some automatically generated html elements from django, to do this I was told to use the each() function in jquery to act on each element with the same class name. The script sort of works without the each() function, but it only changes the first element rather than each individual element. With the each function in place, no values are changed so I'm not sure what to do. javascript $(document).ready(function() { $('.fix-button').each(function() { $(this).on('submit', function(e){ e.preventDefault(); issue_id = $(this) $.ajax({ type: 'POST', url: '{% url "fix_issue" %}', data: { issueid: issue_id.val(), csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(), action: 'post' }, success: function (json) { document.getElementById("fixed_bool").innerHTML = json['result'] console.log(json) }, error: function (xhr, errmsg, err) { } }); }); }); }); my views.py if its necessary def FixView(request): if request.POST.get('action') == 'post': result = '' id = int(request.POST.get('issueid')) issue = get_object_or_404(Issue, id=id) if issue.fixed == False: print(issue) issue.fixed = True result = str(issue.fixed) issue.save() else: issue.fixed = False result = str(issue.fixed) issue.save() return JsonResponse({'result': result, }) -
No module named... in Django proyect
I have a pretty standart Django project and i can't find a way to import /middleware/utils/compare.py from /middleware/utils/request.py This is the proyect tree: |--middleware/ | |--utils/ | | |--compare.py | | |--request.py | |--__init__.py | |--asgi.py | |--settings.py | |--urls.py | |--views.py | |--wsgi.py |--manage.py Where __init__.py, asgi.py, settings.py, urls.py, wsgi.py have no major modifications. (__init__.py is empty) # middleware/views.py from .utils.request import requests # This line works fine # middleware/utils/request.py from compare import compare # ModuleNotFoundError: No module named 'compare' from .compare import compare # Attempted relative import beyond top-level package pylint(relative-beyond-top-level) # ^^^ This line absolutly breaks my code, but it runs from utils.compare import compare # ModuleNotFoundError: No module named 'utils' from .utils.compare import compare # ModuleNotFoundError: No module named 'middleware.utils.utils' Note: compare.py has a function named compare, i also tried renaming it but had the same problems. This might be obvious, but i run the proyect with python manage.py runserver
