How to send emails from Gmail without turning off "allow less secure apps" setting?
Is there any way to send an email in a Django project without turning on the "allow less secure apps" feature? Is using OAuth2 a must or can I send it using Google's API? So far, I just use: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = '587' EMAIL_HOST_USER = 'myemailaddress' EMAIL_HOST_PASSWORD = 'password' EMAIL_USE_TLS = True EMAIL_USE_SSL = False But this gives me an SMTPAuthenticationError, which only works when I turn on "allow less secure apps" in Google. Is there any way to circumvent this without using OAuth2 and allow multiple users to login to that account easily? -

Accurate progress bars to load tweets from twitter
I'm trying to load tweets from the user timeline in twitter and display a progress bar while doing so. In order to use the progress bar, you have to know that amount of 'work' that needs to be done to complete the task. The problem is, the count that you specify in GetUserTimeline is not necessarily the number of tweets that is returned to the call(on account of deleted tweets and so forth the amount of tweets returned maybe less). This means that you can't calculate the number of calls that have to be made to the Twitter API to achieve your target number of retrieved tweets, without loading the tweets beforehand. Can anyone think of a solution?? -

Reload table data in Django automatically
I am trying to solve an issue regarding reloading table data in Django without refreshing the page. I was experimenting with this example but I am having a difficult time to modify it to my needs.

django-rest-auth redirects settings not working as expected
I am using django-rest-auth and django-allauth to handle user authentication in my rest api. The issue is the redirects are not working as expected.

Django Add Choices Directly From Admin Not Working
When I try to add a subject from admin into the Subject model's name field, I am getting an error when I try to save the entry (see admin image below). I'm using the latest Django 3 and Python 3. This code used to work with Django 2 but since the upgrade, it does not populate anything into a blank SUBJECT_CHOICES() from admin. What I want to do is directly add subjects from admin into the database so that these subjects will populate the subjects dropdown menu in my forms.py. In other words, I want my dropdown menu from forms.py for the subjects to populate all of the subjects that I add directly from admin (see image below for an example dropdown menu with all the subjects entered). I see two different ways of solving this but I am unsure how to code them. Either just use a ForeignKey with SubjectName model, or a simple CharField without choice and customize the input widget into a dropdown. I might still need something custom for the form if I were to have dropdown-select and also type-in new choice from admin.

Counting 2 Querysets Deep within Django Template
Is there a way to count within a Django template on a 2nd deep queryset connected via FK's/M2M's? For instance, Model A is FK'd to Model B, and Model B is M2M'd to Model C {% for C in Cs %} {% for B in C %) {% if B.A.all.count >= 2 %} B Has multiple A's! {% else %} B only has 1 A! {% endif %} {% endfor %} {% endfor %} Basically, I want to count the number of A's within B, and if it's 2 or more, just display "Multiple," as actually listing them out is disrupting my template. But I can't seem to get it to work. At the same time, the below DOES work for me: {% for C in Cs %} {% if C.B.all.count >= 2 %} C has multiple B's! {% else %} C only has 1 B! {% endif %} {% endfor %} I just can't get it to go one queryset deeper. Any help? Do I have to do this within the views?
