Why does django admin change_form has a sorting by Primary Key query? Isn't it fetching just one object to edit it?
I have a payments_event model that has millions of data, when I click on one of them to edit it, the page takes tooo much time to load, and when I look at the queries, it has this query: SELECT ••• FROM "payments_event" ORDER BY "payments_event"."id" DESC And it's duplicated two times.. -

I am not sure how to request Django rest-framework Social Oauth2

Data not being saved to database with django forms

How to force pip to install last version of django?
There are have many versions of python on my ubuntu. I have set the default version for python command to 3.7 using alias. I have created a virtual env using virtualenvwrapper and want to install django on this virtual. After activating this virtual if I type python command, version 3.7 runs. But if I type 'pip install Django' the old version 1.13 which is related to python 2.7 is installed. I have tried to use 'pip install Django==2.2.6' but no success. It says: DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support How can I force pip to install version related to python 3.7? -
How can I create a python console in VS Code that includes django app settings?

Bootstrap_form inherit the types from the model
I’m new to Django and bootstrap, so apologies if this is a very basic issue. I’ve defined my model, created my (CreateView) view and am using {% bootstrap_form form %}. It displays nicely, but the field are all the same length on screen and don’t size to the definition in the model (I.e, a date field is much longer than defined in the model). How can I get my form to inherit the size/ width defined in the model? -
Django temporary fields only upon creation
Consider two models: Contract class Contract(models.Model): employee = models.OneToOneField(Employee, on_delete=models.CASCADE) contract_type = models.ForeignKey(ContractType, on_delete=models.CASCADE) start_date = models.DateField() end_date = models.DateField() and Employee class Employee(models.Model): first_name = models.CharField(max_length=20) last_name = models.CharField(max_length=20) contract = models.OneToOneField(Contract, on_delete=models.CASCADE, null=True, blank=True) I was wondering if there's a way to add temporary fields in a model form that are only shown upon creation in the Employee model so I can add all those fields while I create a new Employee then when saving, I first create an Employee object, then automatically generate a Contract object and edit the original Employee object and link the now generated Contract object. I really hope this makes sense, and if it does, can someone guide me in the right direction? Thank you, for your time reading this. -
Creating professional user registration with Django rest framework
I am trying to create a good professional user registration and authentication for a personal project I am building, that sends emails to authenticate users’ email.

For some reason, it still hasn’t been able to work out for me. -
Creating unique identifiers for urls
I'm currently trying to develop an application. I am using Django framework for my backend. Now in my app I will show stuff like posts or pictures. Initially I just used the primary key to display inside the urls. I was told that this wasn't so good because it reveals too much information to a potential attacker. Instead I should use uuid. I read into uuid and now realised that they are very handy. Also I read in some posts also here on SO that uuid may not have enough randomness and could be guessable. A solid alternative would be to use the secrets module from python. Since I'm not experienced enough to make a good assessement I'm reaching out to more experienced developers. Would you just stick with uuid and maybe shorten it or go with the secrets module of python. Please note that as of now I won't be using the id for anything else than uniquely identifying an object. Is it okay to use uuids of 32 characters length? The url will get kind of long. -
changing from address on send_mail
I've hooked in Gsuite as my SMTP server. It sends out emails and it works very well. However, when using the send_mail function in django, I want to indicate a from address other than the email address that I have hooked into Gsuite, which is admin@mywebsite.com. subject = 'Order Confirmation' from_email = "jim@gmail.com" to_email = ("james@gmail.com",) txt_message = "some text" html_message = "some other text" send_mail(subject, txt_message, from_email, to_email, html_message=html_message, fail_silently=False, auth_user="admin@mywebsite.com", auth_password="PASSWORD" ) When an email is sent out with this code, when I look at the resulting email email in the email client of james@gmail.com, the "from" address is admin@mywebsite.com rather than jim@gmail.com. Is there a way that I can change this so that the 'from' is jim@gmail.com or at least the 'reply-to' is jim@gmail.com? Thanks for your help! -
How can I create object of the extended model of User on Django

Django: How to use views&forms of an app in main templates?
I'm using edge repo for quick starting a django project. The repo has an app called "accounts" which handles signin up, logging in, etc with crispy forms. However i'd like to allow users to sign up from the home.html which isn't located in accounts/templates. I have tried adding the following code to home.html: {% if not user.is_authenticated %} {% include "signup.html" %} {% include "auth_base.html" %} {% block form %} {% crispy form %} <div class="form-message"> <p> Already signed up? <a href="{% url 'accounts:login' %}">Log in</a>. </p> </div> {% endblock form %} {% endif %} However since the main views.py can't locate views/forms in account app i'm faced with the following error: django.template.base.VariableDoesNotExist: Failed lookup for key [form] in [{'True': True, 'False': False, 'None': None}, {}, {}, {'view': <my_env.views.HomePage object at 0x7f0ed11cec88>}] My project files are the same as here with only "project_name" being different. I expected to be able to use the signup form in home.html. Can anyone point me the right way?
