Django // How do I need to setup user data management?
I'm working on a pwa with django and I almost done all the front/backend and I'm now facing which might be the last part to put in place (I believe and hope so !) : User Data Management I already had a look at Django's documentation regarding user/group management and I think it is quite logical and understandable however I'm really stuck on how should I implement all of this according to my project ? And especially how should I manage user's data ? Today, the development part is already setup with models/data saving/editing. But there's no user dimension for now, everything created and stored in the database is "general" (I'm using SQLite3 mainly because it was easier to deal with for development and testing but I'm clearly not fixed to it and I can easily readapt parts of the code based on the chosen database and how it work, even more if other database are better adapted to what I am looking for). To give you a bit of context the application should allow anyone to create an account to access the app. When he user is logged on, he/she will be able to arrive on an interface with … -
Optimal Way to Add Dynamic Fields or Preload Initial Values for Django Models
So... I'm working on Django Project in which a question form will be presented to the user. The questions are all yes or no so it will be easy to do that on a database. NOT! for me at least. I've been scouring Google, Django Docs, et al. looking for an answer to this however the only answer I can think of is the one I will be presenting below. GOAL: Make a model class named EmployeeMedicalQuestions in which I will store all the responses sent by a user referencing a One-to-One Relationship with EmployeeProfile. PROBLEM: I have realized that to ask the same questions for all the users, I need to reinitialize the questions for each of them because of the One-to-One Relationship. With my novice experience in Django and Python, I really don't have any idea how to do this 'programmatically'. I also don't want to hard-code the questions (because they might change) as model.BooleanField() one-by-one because I'm too lazy to do that and defeats the purpose of 'dynamic' content. And it's boring. OPTIMAL SOLUTION: I have created a way to overcome this, though by programmatically creating multiple model.BooleanField() variables. Take a look at the code below: models.py … -

Django, don't localize datetimes in views
I'm having trouble understanding how timezones in Django works. Let's say I have a third party API that I get data from with a timestamp of: 2020-10-26 05:00:00 now, let's say that in my view I have a query that filters all of the records from Yesterday ( October 26th) if I have a user that looks at that endpoint in the states, he will see data from October 25th (because in his time zone he is still on the 26th) but I want him to see the data as if he was on the time zone of the original request so he can see this time stamp. -
Use nested dictionary as a datasource for Datatables
I'm new to JS and Django. I have a nested dict in python containing some data that I'd like display in Datatables in Django framework. The dict looks like: {'report': {'country': {'country1': {'POP Count': 15.0, 'POP Age': 2.0, 'Issues': 35.0}}, {'country2': {'POP Count': 16.0, 'POP Age': 1.0, 'Issues': 2.0}} {'city': {'city1': {'POP Count': 16.0, 'POP Age': 1.0, 'Issues': 4.06}}, {'city2': {'POP Count': 16.0, 'POP Age': 1.0, 'Issues': 3.099}} }}} The webpage has two datatables - per country and per city and I'm trying to use this dict above as the datasource in the following way: {{ report.country|json_script:"country_json" }} {{ report.city|json_script:"city_json" }} var country_json = JSON.parse(document.getElementById("country_json").textContent); var city_json = JSON.parse(document.getElementById("city_json").textContent); $('#CountryTable').DataTable({ "data": country_json, "column": [ { "data": "POP Count" }, { "data": "POP Age"} ] }) What I'm trying to achieve is for the Country Table to look like this: Country | POP Count | POP Age | Issues -------------------------------------- Country1| 15.0 | 2.0 | 35.0 Country2| 16.0 | 1.0 | 2.0 When I do this, the datatable goes wonky with all my leaf items merged as a string into a single column. I think the nested dictionary isn't being read properly. How do I get my nested dict get read … -
how to modify nested object field inside get_object

Response from Google Cloud Platform to Django app

The app is expected to work like, whenever a post request is received to the corresponding view, the response should be an audio file .

Provide a specific folder in the media folder for the user to download
Consider that there are three models that are related: class User(AbstractUser): # Its fields class Event(models.Model) user = models.ForeignKey('User', on_delete=models.CASCADE) # other fields class Event_file(models.Model): event = models.ForeignKey('Event', on_delete=models.CASCADE) file = models.ImageField(upload_to='{1}/{2}'.format(self.event.user, self.event) So we will have this structure in the media folder: media User 1 event 1 (where there are several photos) event 2 (where there are several photos) event 3 (where there are several photos) User 2 event 1 (where there are several photos) child 2 (where there are several photos) How can I provide a button in the web page for each user to download their own folder (ie user folder)? Although the user folder may need to be zipped for download. Note: Folder contents are not fixed and may change over time. Thank you in advance -

Django Filter show default last 30 days
Right now I have a filter that allows me to show objects from a specific date range. It's gotten to the point though where it does not make sense to show the full date range. One always ends up filtering for at least the month or last month. How can this month be set up by default?
