no module named parsing when importing django models to python script
Hi there Im having issues importing my models into my application called parsing project structure looks like: manage.py enumproject/ db.sqlite3 parsing/ with enumproject/settings.py I have it in INSTALLED_APPS: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', #'parsing', 'parsing.apps.ParsingConfig', ] models.py under parsing/models.py has: from enumproject import models # Create your models here. class tbl(models.Model): nm=models.CharField(max_length=20, unique=True) dtAdded=models.DateTimeField() #etc... im attempting to run parse.py from parsing/parse.py from parsing.models import * #python code here when I run this file, I get: Traceback (most recent call last): File "parse.py", line 8, in <module> from parsing.models import * ModuleNotFoundError: No module named 'parsing' thoughts? -
Question about parsing a URL generated during a button click event in HTML
I built a form in HTML5 to take input from users. I'm using the GET method. I want to assign the data the user put into the form and assign it to variables in a python script, which will do some logic then render another page at the end of the script which will present the data to the user. I have been researching the past day or so about different methods by which this can happen. I'm running on Django right now. I was going to use CGI, because the syntax seemed pretty straightforward: import cgi form = cgi.FieldStorage() py_var = form.getvalue('name-in-html-tag') But from what I've read is that this method is only suitable for cgi scripts. When I print() py_var I continually get a value of None. So I started reading about using the urllib package to parse GET method urls. But the examples I keep finding online show the URL hardcoded into the scripts, which isn't much help in my situation. Is there a way that I can get the URL generated from the GET method so that I can parse it and use the data in a python script? Everyone seems to have their own way … -
Django save() method executed twice

unable to render the context value in django template on ubuntu server
I have this piece of code that is working fine on my PC environment (virtual environment) but causing problems in a ubuntu, Nginx server. It is a digital ocean droplet actually. I am not very much familiar with ubuntu that's why I am unable to understand the cause of the problem. Now the problem is, that the 'checkout.html' template doesn't render the value of 'fire'. I have tried to troubleshoot manually and in the 'inspect' window I only see an empty label. Why is this happening, is it because of the django=2.2.3 version or ubuntu or Nginx or am I missing anything here? Note: I am updating the files through Filezilla. Kindly help, please. Views.py def checkout(request): return render(request, 'checkout.html', {'fire':"fire"}) checkout.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <label>{{fire}}</label> </body> </html> urls.py from .views import * path('checkout-page', checkout, name="checkout"), -

Django i18n - how to translate included templates
I have a django project using i18n for translations. When I type : python3 manage.py makemessages -a All my project templates and views are processed to build the django.po file except the templates that are included within another template. Example the high-level template has: {% include 'journey/journeysTable.html' %} With journey/journeysTable.html looking like: {% load i18n %} {% load static %} <table class="table table-striped caption-top tableRowIsLink"> <thead> <tr> <th scope="col">{% trans "Code" %}</th> <th scope="col">{% trans "Name" %}</th> {%if hide_user is None %} <th scope="col">{% trans "Artist" %}</th> {% endif %} <th scope="col"></th> <th scope="col"></th> </tr> </thead> <tbody id="journeysTableBody"> ... </body> </table> The {% trans %} tags do not produce any error, but associated text is not in the django.po file. journey is an app and the included template is in journey/templates/journey/ folder. Other templates in the same folder are translated. Is it a normal behaviour? I understand that both templates are rendered separately but they should both be translated. -

Advance django filters
I am working on a management system. Where I have models: class FeeType(models.Model): name = models.CharField("fee Type", max_length=200) duedate = models.DateField("due date") class Meta: verbose_name_plural = "Fee Type" def __str__(self): return self.name class CollectFee(models.Model): boarder = models.ForeignKey(Boarder, on_delete=models.CASCADE) feetype = models.ForeignKey(FeeType, on_delete=models.CASCADE) amountpaid = models.PositiveIntegerField("amount Paid") class Meta: verbose_name_plural = "Collect Fee" def __str__(self): return self.boarder.name Now in a template I want to show the list of all the boarders/students, who have not been assigned the last fee. e.g if "July Fee" is the last object in the FeeType model then show all those boarders who have not been assigned the JulyFee. I have tried a view for this: def feedue(request): last_fee_type = FeeType.objects.last() boarders = CollectFee.objects.exclude(boarder__collectfee__feetype=last_fee_type) context = {'boarders':boarders} return render(request, 'fee-due.html', context) It does not show the boarders who have been assigned the last feetype, that's correct. But if the boarder is not assigned the last feetype then it shows the boarder name as many times as he have been assigned the previous feetypes. Hope you understand. Help please. -

Django rest framework - Limiting get request access to only authorized user

Django - Google Analytics not tracking properly

Resolve Django/DRF ImageField URL from F() function
I have a use case where I'm attempting to override an Image URL if it exists in our database. Here is the section of the queryset that is grabbing the ImageField from via an F() query. preferred_profile_photo=Case( When( # agent not exists Q(agent__id__isnull=False), then=F("agent__profile__profile_photo"), ), default=Value(None, output_field=ImageField()), ) The Case-When is resolving correctly, but the issue is the value returns from F("agent__profile__profile_photo") is not the URL than can be used by the UI. Instead it is something like: "agentphoto/09bd7dc0-62f6-49ab-blah-6c57b23029d7/profile/1665342685--77e51d9c5asdf345364f774d0b2def48.jpeg" Typically, I'd retrieve the URL via agent.profile.profile_photo.url, but I receive the following when attempting to perform preferred_profile_photo.url: AttributeError: 'str' object has no attribute 'url'. I've tried wrapping in Value(..., output_field=ImageField()) with no luck. The crux here is retrieving the url from the ImageField after resolving from F() For reference, I'm using storages.backends.s3boto3.S3Boto3Storage. Appreciate any help! -
