How to get users spent time on a task with Djanog?
I have Django project and several views. In one view i want to track users spent time. How can i do that? Maybe some libraries or django built in methods? Little bit more about view: when user open view he can see many photoes, and then he need to choose similar and save. Then page reloads with new photoes and task is similar, find similar photoes and submit. I need to track and store that time what each user spent on this task. If i check users time when he open view i don't know when she close it, and also user can just open view and chill, without doing something. How or with i can realize it? -
How do I include a Django project's README.md in a template?
I want to add the text of the readme to a custom index template in admin. So I have the following relevant paths in the project: ./README.md ./impact_api/templates/admin/index.html And in the project settings I have TEMPLATES = [ { 'DIRS': [BASE_DIR / 'templates'], ...}] So in the index.html file I want to do something like this: {% include "../../README.md" %} But that raises an error: TemplateSyntaxError at /admin/ The relative path '"../../README.md"' points outside the file hierarchy that template 'admin/index.html' is in. The only things I can think of are a) to move the README into the body, which I'm not sure I can do without losing the display on Github and seems like a bad idea even if I can, or to change the templates lookup path to the entire project, which also seems like a terrible idea. Is there a more sensible option? -

Django Bootstrap 5 - Custom styling
I am using django-bootstrap5 in a Django project. According to the docs, for customization, I can add the following to settings.py: BOOTSTRAP5 = { "css_url": {}, # I could add a custom URL here "theme_url": "..." # Or I could override the theme here } Which seems overkill for only a few customizations. How can I customize something like the primary colour of Bootstrap? Do I have to use Sass/Scss, and if so, how does one do this in Django? -

How to deploy Django Based Server and Laravel Project Simultaneously on a Single Droplet
I am new to Digital Ocean and was wondering on how to deploy Django and Laravel code side-by-side. The code works fine locally but I don't know how to deploy the both sources over Digital Ocean droplet. We bought cloudways server but it doesn't offer anything other than PHP which was the limitation. So, we don't have any experience with deployment on Digital Ocean. Is there anyone who can help me with this? Thank you! -

Django Unknown column in field list error

Django Detail View on Boostrap Modal?
Am in the process of building an Ecomerce app with django and although am comming along just fine, I can't seem to be able to render the details of a specific object on a bootstrap modal.

Django UUID Field does not autocreate with new entry
I just added a new model where I want to use a UUID for the first time. I run django 3.1.3 on python 3.8.10. Found some questions about this and I am quite certain I did it according to those suggestions. However, when I add an entry to that model (in phpmyadmin web-surface) the UUID is not being added, it just stays empty. However when I create an other one I get the error, that the UUID Field is not allowed to be the same as somewhere else (both empty) wich means at least the unique=True does work. Another thing to mention is, when I create the field using VSCode, normally those fieldnames are being auto-completed, however it is not the case with this one. Thought this might give you a hint what is going on. My model looks like this: from django.db import models import uuid class MQTTTable(models.Model): uuid = models.UUIDField(primary_key = True, default = uuid.uuid4, editable = False, unique = True) description = models.CharField(max_length= 100, default = None) clientID = models.CharField(max_length = 50, default = None) mastertopic = models.CharField(max_length = 200, default = None) -

How to query User model by 'custom' fields? (django.db.models.fields.related_descriptors.ReverseOneToOneDescriptor)
I extended the User model using my account app. Model Account app: from django.db import models from django.contrib.auth.models import User from departments.models import Department class Account(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) profile_pic = models.ImageField(upload_to='profile_pics', blank=True) department = models.ForeignKey( Department, on_delete=models.SET_NULL, null=True, related_name='department') def __str__(self): return self.user.username Now I need to send the count of users from the same department to my template... View: from django.contrib.auth.models import User @login_required def home(request): context = { 'title': 'Dashboard', 'department_members': 'department_members': User.objects.filter(department=request.user.account.department).count(), } return render(request, 'app/dashboard.html', context)\ department_members is always 1 even though I have more users on the same department. I figure that the problem is that User don't have department field by default, so I can't say User.account.objects.filter(department=request.user.account.department) I've tried a lot of queries and looked into django docs but I could't find the proper manner on how to retrieve this info. Anyone have the same problem? Any tips on how I can debug/create my query in a better way? Thanks to all in advance! -

Django convert model objects to dictionary in large volumes results in server timeout
I have been having a problem where a Django server takes forever to return a response. When running with gunicorn in Heroku I get a timeout, so can't receive the response. If I run locally, it takes a while, but after some time it correctly shows the site. Basically I have two models: class Entry(models.Model): #Some stuff charFields, foreignKey, TextField and ManyToMany fields #Eg of m2m field: tags = models.ManyToManyField(Tag, blank=True) def getTags(self): ret = [] for tag in self.tags.all(): ret.append(getattr(tag, "name")) return ret def convertToDict(self): #for the many to many field I run the getter return {'id': self.id, 'tags' : self.getTags(), ... all the other fields ... } class EntryState(models.Model): entry = models.ForeignKey(Entry, on_delete=models.CASCADE) def convertToDict(self): temp = self.entry.convertToDict() temp['field1'] = self.field1 temp['field2'] = self.field1 + self.field3 return temp Then I have a view: def myView(request): entries = list(EntryState.objects.filter(field1 < 10)) dictData = {'entries' : []} for entry in entries: dictData['entries'].append(entry.convertToDict()) context = {'dictData': dictData} return render(request, 'my_template.html', context) The way it was done, the dictData contains the information for all the entries that must be shown in the site.

django: Query regarding radio buttons
The requirement is that I have a set of questions, and I want the responses to be provided by selecting a value which is rendered using radio buttons. The issue here is, say, we have: Question 1: o option 1 x option 2 o option 3 Question 2: o option 1 o option 2 o option 3 where 'o' represents un-selected options and 'x' - represents an option that has been selected. Now, when trying to check option3 under question 2 it unselects the response to the previous question i.e., Question1. Question 1: o option 1 o option 2 o option 3 Question 2: o option 1 o option 2 x option 3 How do we decouple the radio button responses for each field?? Any help would be appreciated. Thanks!! -
How to force insert custom value in datetimefield(auto_now_add=True) while object creation in Django?
I have a model Test in service A class Test(models.Model): some_field = models.IntegerField() created_at = models.DateTimeField(auto_now_add=True) I am migrating data from a different service B's model to this model (using APIs). Exposed an API in service A which reads from POST data sent from the B, and saves the data in this Test model. Sample data coming from service B data = { 'some_field': 5, 'created_at': '2013-06-26 00:14:27.260524', } Now when I save this data in the db using: obj = Test( some_field=request.POST.get('some_field'), created_at=request.POST.get('created_at'), ) obj.save() The created_at values of saved object is the current time. Not the created_at coming from the API. How to bypass this current time saving in this scenario and save the timestamp coming from the API while creating the object?
