Django - Error during template rendering for crispy forms with dynamic fields : 'int' object has no attribute 'get'
I have been trying to implement dynamic forms with a given number of fields and rendering these with crispy forms. However, the following errors are coming when rendering the page: Template error: In template C:\Users\USER14\Documents\testprep\lib\site-packages\crispy_forms\templates\bootstrap4\errors.html, error at line 1 'int' object has no attribute 'get' 1 : {% if form.non_field_errors %} 2 : <div class="alert alert-block alert-danger"> 3 : {% if form_error_title %}<h4 class="alert-heading">{{ form_error_title }}</h4>{% endif %} 4 : <ul class="m-0"> 5 : {{ form.non_field_errors|unordered_list }} 6 : </ul> 7 : </div> 8 : {% endif %} 9 : Traceback (most recent call last): File "C:\Users\USER14\Documents\testprep\lib\site-packages\django\forms\forms.py", line 304, in non_field_errors return self.errors.get(NON_FIELD_ERRORS, self.error_class(error_class='nonfield')) File "C:\Users\USER14\Documents\testprep\lib\site-packages\django\forms\forms.py", line 170, in errors self.full_clean() File "C:\Users\USER14\Documents\testprep\lib\site-packages\django\forms\forms.py", line 372, in full_clean self._clean_fields() File "C:\Users\USER14\Documents\testprep\lib\site-packages\django\forms\forms.py", line 384, in _clean_fields value = field.widget.value_from_datadict(self.data, self.files, self.add_prefix(name)) File "C:\Users\USER14\Documents\testprep\lib\site-packages\django\forms\widgets.py", line 657, in value_from_datadict getter = data.get Exception Type: AttributeError at /upload/1/SingleCorrect/10/ Exception Value: 'int' object has no attribute 'get' What exactly prompts this error?

Django Modelform ForeignKey Listing Problem
I have a staff list. I have a model for this as follows. models.py: class NumberOfMealsEaten(models.Model): month = models.ForeignKey(Months, on_delete=models.CASCADE) staff = models.ForeignKey(Staffs, on_delete=models.CASCADE) maelseaten = models.IntegerField("Number of meals eaten", validators=[MinValueValidator(0)], default=0) def __str__(self): return str(self.staff) For these employees, the meal fee is calculated every month according to how many meals each staff has eaten. First, at the beginning, I want to choose "the name of the relevant month" only once. Then I want the staff names from Foreignkey to be automatically listed as "text" in the template, not in the form of a drop-down menu. So I just want the "maelseaten" field filled in for the staff. As an example, the list will look like this: enter image description here In other words, this form will add the number of meals for each staff member for the selected month to the database. Thank you in advance for your attention and help. -
Increment number until it matches another number
I am trying to write an algorithm that will increase portion size until the total_cals are as close to the specified argument calories as possible. Here is my model: class Foods(models.Model): name = models.CharField(max_length=100) calories = models.IntegerField() protein = models.FloatField() carbs = models.FloatField() fat = models.FloatField() sugar = models.FloatField(null=True) fiber = models.FloatField(null=True) amount_in_grams = models.IntegerField(default=100) portion_size_in_grams = models.IntegerField() Here is the function I have: def mealPlanMaker(calories): total_cals = 0 meal = [Foods.objects.get(name='Rice'), Foods.objects.get(name='Broccoli'), Foods.objects.get(name='Chicken') while calories > total_cals: for i in meal: portion_size = i.portion_size_in_grams + 1 total_cals += i.calories * portion_size / 100 meal_dict[i.name] = portion_size meals.append(meal_dict) So what I want to do is increase the portion size until the total_cals is as close as possible to calories, say within a range of 50. But my function doesn't work. -
Django access grandchild instances from grandparent

Django: update not saving date without raising error
I have a view in my Django app where I want to update a queryset´s DateField. It´s quite simple, the field works fine in other views (not a model problem) and it doesn´t raise any error when running the view. The other elements in the view are stored ok. The view @transaction.atomic @login_required def BocetoArmando(request): operaciones = OperacionK.objects.filter(creador__username='this_user', estatus__id=1) operaciones.update( fecha_conf_comercial=date.today(), fecha_conf_admin=date.today(), confirmador_admin=request.user, estatus=EstatusOperacionK.objects.get(estatus__icontains="Armando")) lista = [x.id for x in operaciones] pedidos = PedidosK.objects.filter(comprobante__in=lista) pedidos.update(fecha_conf_comercial=datetime.datetime.today()) for pedido in pedidos: producto = ProductosBase.objects.get(pk=pedido.producto.id) producto.existencias = producto.existencias - pedido.uds producto.existencias_bloqueada = producto.existencias_bloqueada - pedido.uds producto.save(update_fields={'existencias', 'existencias_bloqueada'}) return DispatchManager(request) I tried both options with the same result: pedidos.update(fecha_conf_comercial=datetime.datetime.today()) pedidos.update(fecha_conf_comercial=date.today()) If I run pedidos.update(fecha_conf_comercial=date.today()) in Django´s shell it´s updated correctly. This is part of a big app that handles this datefield without any problems in the rest of the views. I can´t figure out what is happening here. Any clues welcome. Thanks in advance! -
How to have django-admin recognized in Eclipse/LiClipse?
I've been trying to execute django-admin from within a LiClipse project using: projectName = "someProject" command = 'django-admin startproject ' + projectName process = subprocess.Popen(command.split(), stdout=subprocess.PIPE) and also subprocess.check_call(shlex.split(command)) But each time I get the error: FileNotFoundError: [Errno 2] No such file or directory: 'django-admin' However, when I run the same program from the Linux terminal using python3 main.py, it works fine. So I figured it might be because django-admin's path isn't added to PYTHONPATH. I did a locate "django-admin" to find these paths: /home/nav/.pyenv/shims/django-admin /home/nav/.pyenv/shims/django-admin.py /home/nav/.pyenv/versions/3.8.7/bin/django-admin /home/nav/.pyenv/versions/3.8.7/bin/django-admin.py /home/nav/.pyenv/versions/3.8.7/bin/__pycache__/django-admin.cpython-38.pyc /home/nav/.pyenv/versions/3.8.7/lib/python3.8/site-packages/django/bin/django-admin.py /home/nav/.pyenv/versions/3.8.7/lib/python3.8/site-packages/django/bin/__pycache__/django-admin.cpython-38.pyc and added it to PYTHONPATH... ...but I get the same error when I run the program from within LiClipse. Does anyone know why this problem is happening and how it can be fixed? -

load multuple dummy data dinago for windows
I have this script python manage.py loaddata ./project_apps/*/fixtures/test/*.json It works perfectly on linux. This scrip says 'take all dirs from /project_apps, in every dirs, if there is fixtures folder take it and than search for /test dir, if there is take it and grab all files there which have .json extension'. That is fine, but when i run the same command on windows python manage.py loaddata .\project_apps\*\fixtures\test\*.json it throws me an error: there is no fixtures with that '*' name If i pass the absolute path to the file which a want. It is ok. The windows finds it. So is there an analogous command for windows, to can grab all files i want at once. -

DRF simpleJWT - Is there anyway to fetch user's data from an access-token with no access to the 'request' param?
I'm trying to write a custom authentication middleware for Django channels since I'm using JWT for my app's authentication scheme. I'm using the method that is mentioned in this article which basically gets user's token in the first request that is made to the websockets and then, in the receive method of the consumers.py file, fetches user's data based on that and then pours it in the self.scope['user'] (can't make use of the token_auth.py method because the UI app is separate..). Now since I have NO ACCESS to the request param that is usually being used in the views.py files to get the user's data, is there anyway to get the user's data out of an access token alone?? -
django-simple-history - Filter model as of a date
I'm trying to filter an Employee model based on their business, but to keep statistics accurate I want to be able to also get all of the employees as of a specific date. Using django-simple-history I can do Employee.history.as_of(date) which returns a generator object with the employees as of that date. Is there a way that I can use the as_of() method in conjunction with djangos object filtering? I could loop through the generator and do the check within that, but I imagine that would be inefficient. -
