how to show my post only to my friends in django
I want to show my post only to my friends, How can I filter my post only to my friends? I have tried to filter in html code but as my friends get more, it repeats my post more (I mean repeat one post few times ) My models.py class PostUser(models.Model): posttype = models.CharField(max_length=3000, default='postuser') content = models.TextField(null = True, blank= True) media_image = models.FileField(null = True, blank= True) media_video = models.FileField(null = True, blank= True) per_to = models.CharField(max_length=300, null=True, blank=True, default='everyone') status = models.CharField(max_length=3000, default='active') date = models.DateField(auto_now_add=True) time = models.TimeField(auto_now_add=True) datetime = models.DateTimeField(auto_now_add=True) like = models.IntegerField(null=True, blank=True) comment = models.IntegerField(null=True, blank=True) share = models.IntegerField(null=True, blank=True) user_pk = models.IntegerField() class Friends(models.Model): # Sender friend_one = models.IntegerField() # Reciver friend_two = models.IntegerField() per_to = models.CharField(max_length=300, null=True, blank=True, default='everyone') status = models.CharField(max_length=3000, default='active') datetime = models.DateTimeField(auto_now_add=True) date = models.DateField(auto_now_add=True) time = models.TimeField(auto_now_add=True) and this is my views.py allmyfriends = Friends.objects.filter(Q(friend_one = request.user.pk) | Q(friend_two = request.user.pk)) -
How to auto-update the slug field in Django admin site?
I know how to auto-populate the slug field of my Blog application from post's title, and it works fine. But if I edit the title the slug field is not changing. Is there any way to have it updated automatically? I use Django's admin site. Thanks. -
Django define update_fields when creating objects in model
I am using a SQL Server table with period columns, and my model in Django is defined as class Client(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(unique=True, max_length=40) sys_start_time = models.DateTimeField(db_column="SysStartTime") sys_end_time = models.DateTimeField(db_column="SysEndTime") class Meta: managed = False db_table = "client" where sys_start_time and sys_end_time are period columns. Due to sql server rules, any query defining values for these columns are invalid, which means that the sql query django generated when creating or updating this model won't work. I managed to exclude them in update_fields when performing update so that django will generate queries without period columns, but I can't use the same update_fields parameter when creating an object, otherwise I get an error saying Cannot force both insert and updating in model saving. Is there a way to let django ignore certain fields when creating an object? OR Is there a way to tell Django to send DEFAULT (sql server keyword, not string) as the value for these period columns? -

How do you implement CSRF tokens in django rest framework?
I have noticed that when using django and you make a post request, using a form for example, django asks you to add the csrf token, but when I was fetching data from an api created with django rest framework with react I realized that when I didn't send the csrf token there wasn't any error with the application. In this app I am using token authentication with knox and I have seen some posts about how to use csrf token with session authentication. My question is if token authentication does not need the csrf tokens or are they passed automaticaly by react? Thanks in advance. -
JavaScript cloning an element with a loop inside
I'm new to coding/web development, I'm using JavaScript function to clone an Element which has a loop inside it. But the function is not working. Following is my HTML code: <table> <tr> <td id="add"> <Select class="selectpicker form-control" name="audience"> <option value="all">All</option> <option value="teachers">Teachers</option> <option value="parents">Parents</option> <option value="students">Students</option> {% for i in range(1,14) %} <option>{{i}}</option> {% endfor %} </Select> </td> <td><button type=button onclick="newfield()" class="btn btn-outline-success"> + </button> <button type=button onclick="remove()" class="btn btn-outline-danger"> - </button> </td> </tr> </table> And following is my JavaScript function: function newfield(){ var newselection =document.getElementById("add").firstChild; var newfield = newselection.cloneNode(true); var x = document.getElementById("add") x.insertBefore(newfield, x.firstChild); } function remove(){ var x = document.getElementById("add"); x.removeChild(x.lastChild); } but when I manually insert the numbers from 1 to 13 in attribute. the function works perfectly. As I'm new to coding space I'd like to know whether there's a way to overcome this problem. Thank you. -
Python requests in CRON job getting called twice
I'm not really sure why but each request I make with the Python requests library is getting called twice. I am sure that the CRON job is not called twice as I'm logging a message to a logfile every time it runs. What might be the possible issue for this? Here is a screenshot of the calls: If you take a look at their times, they're very close to each other. -

Django-rest-auth multiple Google Apps
I am writing a Django REST Application that uses Django-all-auth plugin. I want the user to be able to login both via their Mac or Website. So in my Google Console, I have created 2 OAuth2.0 Apps. One for Mac and one for Website, the difference being that the website one has the redirect URI of my website and the Mac one to have redirect URI of https://google.com Under my Social Applications in admin, I have added both Apps with their Client IDs and Secrets. Now, after logging the user in with Google account, I POST the "access_token" returned to Django-all-auth google login url at my REST server. Before I only had the Website app and it used to work fine but now I am getting this error: Does it not allow you to have 2 Google Apps attached at the same time? Is there a setting I am unaware of to allow 2 Google OAuth2.0 apps? I couldn't find anything in the docs for this: https://django-allauth.readthedocs.io/en/latest/overview.html Any suggestions will be highly appreciated. -

pylint django with django-configurations
How to make pylint-django work together with django-configurations ? I've setup a Django project in VS code with pylint and django-pylint as linter. I have a conflict with django-configurations, a package that I use to have different config file depending on environment. I specify django-settings-module in order for django-pylint to understand django project. Settings.json in vscode looks like this : { // ... "python.linting.pylintArgs": [ "--load-plugins", "pylint_django", // Works fine // "--django-settings-module", "project.settings" // Do not work anymore when adding this ], ], // ... } Also I've tried the same config file with another django project that does not use django-configurations and pylint django works well with second line on. -
How to repeat a many-to-many relationship in Django?
I have these models in my Django app from django.db import models from django.contrib.auth import get_user_model User = get_user_model() class Animal(models.Model): name = models.CharField(max_length=100, unique=True) class AnimalList(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) list = models.ManyToManyField(Amimal) I want to add the same pokemon to the same list twice: >>> animal = Animal.objects.create(name='milla') >>> user = User.objects.create(username='user') >>> list = AnimalList.objects.create(user=user) >>> list.list.add(animal) >>> list.list.add(animal) >>> animal.save() The animal is added only once, though: >>> list.list.all() <QuerySet [<Animal: Animal object (3)>]> I expected that, the documentation is explicit that Adding a second time is OK, it will not duplicate the relation: Yet, I do want to repeat the animals. How could I do that? Is it possible by using ManyToManyField? -

Caller Device Detection of a Django-Python Rest API
We are developing a REST API using Python-Django. API is consumed by IOS and Andriod native apps and a browser-based web application. With each user login, we need to detect and store the device users are connecting. Right now I have tried to achieve this using django_user_agents. It detects the device correctly when calls are coming from browsers. But it can't detect the devices of calls from native apps. So I'm just guessing django_user_agents works only for browser-originated calls. I'm kinda new to python and Django world. Any help on how to detect calling devices universally would be really appreciated. Thanks, -
