Django Import Custom Module to Views.py
We have this folder structure: django_app >> views.py django_app >> bot_funcs >> bot.py Both django_app and bot_funcs have blank __init__.py files. We are attempting to import bot.py into views.py. We have tried every combination we can think of, and assumed something like this would work: from .bot_funcs import bot This results in a 500 server error on our website and this traceback in Spyder: Traceback (most recent call last): File "<ipython-input-18-937d4612431c>", line 1, in <module> from .bot_funcs import bot ModuleNotFoundError: No module named '__main__.bot_funcs'; '__main__' is not a package I think this traceback is a red herring, because other imports in views.py (e.g. from .models import Feedback) return the same traceback, but work properly on the website. What is the best way to import from a folder located in the app folder, and why are the usual import methods not working? -
Django Model Fields: Keeping track of list of possible items
I'm creating a Django model, where (as a simplified example) a user group (Users are all assigned to a group) will be able to access files of a certain file type, and which types a group can access will change by group. The list of files can be any of ~10 common file types. This list might change, but that's probably not common. Roughly speaking, I see two ways of doing this. Representing the file types as a list of strings for each user [".jpg", ".txt", ".zip"] or, as a 1:M relationship with some sort of "FileExtension" Object. These are cases in which I imagine the ORM route would be much preferred (Ex: If it's important to keep track of Each file extension's use case as for "image", "text", "audio", etc) But what if there's no other information we really need to consider here but the file extension itself? Is there a reason to create a whole model for just a few strings? In my actual project, I want to avoid the complications of creating and maintaining multiple models and storing those in the DB if I can. Rough Possible Code Examples of each: String/List approach: class UserGroup(models.Model): group_name = … -
My form is not submitting to database in Django

Django how to loop through a model but not inclide the last entry
I'd like to loop through every entry in a django model except the very last item inside of a template. I understand how to do this in python, but unsure of how I might do it inside of a template. Currently my index.html: {% for chat_stream in chat %} <p> <b>bot:</b> <br> {{chat_stream.bot}} <br> <b>{{user}}:</b> <br> {{chat_stream.user}} <br> </p> {% endfor %} The above code loops through entire model how would I not include the last entry (without first processing it in a view.py)? Thank you -
Django's user_passes_test always gets Anonymous User
I'm using the following class-based view and applying the UserPassesTestMixin to it to check some pre-conditions. class SomeTestView(UserPassesTestMixin, APIView): def test_func(self): return check_precondition(self.request.user) def get(self, request): print("inside view") print("user: ", request.user) print("is_authenticated? ", request.user.is_authenticated) return Response({"status": "success"}) Below is my precondition: def check_precondition(user): print("in user_passes_test") print("user: ", user) print("is_authenticated? ", user.is_authenticated) return True Here's the output I am getting: in user_passes_test user: AnonymousUser is_authenticated? False inside view user: John Doe/john@test.domain is_authenticated? True What I'm not able to understand is that why is the request.user anonymous inside the user_passes_test check. I want to run some precondition checks based on the user object.

Django filter __lte __gte strings
I would like to filter models given a user input. For example the user would like to go on a cruise that is 1-5 days long. In the template I have a selector with these values (1-5, 6-9, 10-16, 17+). In the view I create these as kwargs. def create_kwargs(from_date, nights): kwargs = {} got_nights = nights != '-' got_date = False if not from_date else True if got_nights and (not got_date): nights_kwargs(kwargs, nights) if got_nights and got_date: nights_kwargs(kwargs, nights) kwargs['start_months__contains'] = from_date if (not got_nights) and got_date: kwargs['start_months__contains'] = from_date return kwargs def nights_kwargs(kwargs, nights): if '-' in nights: c_min, c_max = nights.split('-') kwargs['cruise_duration__gte'] = c_min kwargs['cruise_duration__lte'] = c_max else: kwargs['cruise_duration__gte'] = '17' Than I feed these kwargs to the filter method: for i, area in enumerate(filter_areas): cruises = GeneralCruise.objects.filter(areas__contains=area, **kwargs) Previously I tried to check equality and it worked: kwargs['cruise_duration'] = '1' My problem is that if I write __lte or __gte it returns all the models even if they are not matching the criteria. I read other questions regarding this and I think this should be working. This is the model: class GeneralCruise(models.Model): company = models.CharField(max_length=255, null=True) ship_name = models.CharField(max_length=255, null=True) ship_img = models.CharField(max_length=255, null=True) cruise_name = … -

Non-pip-installable python modules on Heroku
I am trying to deploy a Django Web-App that, amongst other, implements the IfcOpenShell Python module (http://ifcopenshell.org/python ). Unfortunately, this module is not available through pip install. To use it locally, I just download the files and paste them in my python environment site-packages folder. When I deploy this App on Heroku the IfcOpenShell module is missing of course. Is there a possibility to add it manually to Heroku somehow? -

How to Sum values from different objects in Django?
I want to calculate the workout volume of each user, and then append it so I can use the value in chart.js. This is calculated by multiplying the reps, series, and weight of all exercises in all workouts a user has. I have the following models: class Exercise(models.Model): exercise = models.CharField(max_length=166) series = models.IntegerField(null=True, validators=[RegexValidator(r'^[0-9]*$')]) reps = models.IntegerField(null=True, validators=[RegexValidator(r'^[0-9]*$')]) weight = models.DecimalField(max_digits=5, decimal_places=1, null=True, blank=True) class Workout(models.Model): member = models.ForeignKey(Member, on_delete=models.CASCADE) day = models.CharField(max_length=1, blank=True, null=True, verbose_name="Dias") exercises = models.ManyToManyField(Exercise, blank=True) To try and calculate that workout volume, I used the following in views: data = [] workout = Workout.objects.filter(member=request.user.member) for p in workout: exercise = p.exercises.aggregate(total=Sum(F('reps') * F('series') * F('weight'))).values() for d in exercise: data.append(d) This, in turn, returns the Sum of each single day. So, if a user has 2 workouts, it'll return (example) ["4350.0", "7350.0"] How can I calculate the sum of all days. So, in the case of this example, the final value would be ["11700.0"]. -

How to extract value from Radio Button in views.py in django from request.POST method
I'm trying to get value of a Radio Button from HTML template into views.py file for storing it inside my model. The problem is that it returns "on" always, and I'm using "request.POST['btnradio']" method to get the value/label of my radio button which has name="btnradio" in views.py file. I want it to return that the value/label of that button which is checked. Like if the button with value/label "Foodie" is checked, then it should return "Foodie" so that I can store it in modal. Likewise, if the other one is selected, then it should return "Restaurant".
