Sending emails via gmail is too slow - Django
I'm using the below to connect to gmail server to send emails. EMAIL_USE_TLS = True EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 EMAIL_HOST_USER = 'myemail@gmail.com' EMAIL_HOST_PASSWORD = 'password' The email is working perfectly fine, but it takes around 20 - 30 secs for the process to complete. I know many are facing this issue, but I didn't find a proper answer for this. -

Django - Unable to remain in the view assigned to LOGIN_REDIRECT_URL after redirecting to back page. I'm using custom AUTH_USER_MODEL
I'm trying to get a custom user model named (UserAccount) working for logging in and logging out My custom user account inherits these two classes UserAccount(AbstractBaseUser, PermissionsMixin) Used django.contrib.auth.views - LoginView and LogoutView in accounts app's urls.py file: from django.urls import path from django.contrib.auth import views as auth_views from . import views urlpatterns = [ path('login/', auth_views.LoginView.as_view(template_name="accounts/login.html"), name='login'), path('logout/', auth_views.LogoutView.as_view(template_name="accounts/logout.html"), name='logout'), path('signup/', views.signup, name='signup'), ] When I login, as per the setting LOGIN_REDIRECT_URL, I'm able to get redirected to the landing_page. AUTH_USER_MODEL = 'accounts.UserAccount' LOGIN_URL = 'login' LOGIN_REDIRECT_URL = 'landing_page' LOGIN_REQUIRED_IGNORE_VIEW_NAMES = [ 'login', 'logout', 'signup', ] I've used the django-login-required-middleware and also included these two in my settings file: INSTALLED_APPS = [ 'login_required', # along with others ] MIDDLEWARE = [ 'login_required.middleware.LoginRequiredMiddleware', # along with others ] But whenever I hit back button on the browser, it is again taking me back to login page, even after logging in. Can someone please help resolve this authentication issue? -
How to auto-fill and display data in Django from fields of User model to another model from a different app?
I'm new in Django and right now I'm working to a payment application project for registered users and for non-registered users. My User model has some required fields from the paper invoice like below: #users/models.py class User(AbstractBaseUser): email = models.EmailField(max_length=255, unique=True) name = models.CharField(max_length=100, blank=False, null=False) phone = models.CharField(max_length=11, blank=False, null=False) clientid = models.IntegerField(blank=True, null=False, unique=True) Notice that the authentication process is based on e-mail address and the required field from the invoice payment is "clientid, phone, name". The other app called payments has 1 model class for non-registered users and for authenticated users like below: #payments/models.py class Payment(models.Model): invoiceid = models.IntegerField(blank=False, null=False) name = models.CharField(max_length=50, blank=False, null=False) amount = models.DecimalField(decimal_places=2, max_digits=20) email = models.EmailField(max_length=255, blank=False, null=False) phone = models.CharField(max_length=11, blank=False, null=False) clientid = models.IntegerField(blank=True, null=False, unique=False) For both models I'm using crispy forms, for non-registered users is quite easy to make the payment if they fill all the fields. (different templates are used for this actions). What I want to achieve is when the user is registered and wants to make a payment, the fields like "name, phone and clientid should be filled automatically and displayed to the user in read mode only based on the registration user table. … -
admin site list vs tuple django
when customizing admin site we can use list or tuple like @admin.register(Model_name) class Model_nameAdmin(admin.ModelAdmin): list_display = ['a', 'b', 'c'] # using list # lets say a, b, c are fields of model(Model_name) or list_display = ('a', 'b', 'c') # using tuple I'm curious Is there any difference using a list over tuple or vice-versa like performance while retrieving the admin site or something like that. I know tuples are better than lists for performance but we aren't looping here. I've looked at whats-the-difference-between-lists-and-tuples, why-does-django-use-tuples-for-settings-and-not-lists, why-djangos-modeladmin-uses-lists-over-tuples-and-vice-versa, but didn't get my answer. Is it better to use tuple all the time? I'm asking specifically for the admin site. -

Blacklist the token once there is a changes in role or permission in django rest framework simple-jwt
I would like to blacklist the token (and redirect to login page) once there is a changes in role or permission of a specific user. The admin only can change the role. If any point of time, the role and permission changed it should automatically blacklist the token. I mean there will be a function of blacklist token, if any changes detected that function should execute automatically. Note : user does't have any idea about his role change or not. There will be mechanism that will detect automatically the changes and execute the blacklist method to blacklist the token and redirect to login page. Any inputs would be really appreciated. -
Suggestions on implementing search with Django and Python
I've been venturing recently into python and django, and was looking to build a website that displays information retrieved from a dataset, very similar to this website - https://art-explorer.azurewebsites.net/. This is just a project to develop my skills, and will not necessarily be deployed live. The database currently has a thousands of rows that display information about objects, including tags, metadata, and URLs of images. My goal was to implement a search engine that goes through all of the images linked in the dataset and displays them with some kind of metadata information, such as author, year, title, etc. The user should have the option to filter through these images by selecting tags, specific years, authors or just search by keywords. I already have the basic structure of the website implemented in Django, including the HTML and CSS, and was thinking on using SQLite for the database. I'm pretty new to this, so this may not be the best implementation or even feasible. Do you think this is doable with the current structure I'm going for, is there a better way to implement this in a way that it will be more efficient in the backend? Thanks! -

GEOS_ERROR: ParseException: Unknown WKB type 337
I am coding a geo-based application with geodjango and postgis. I wrote the model and filled the first few points by hand from the admin interface. All worked fine, and I can even search by the nearest points. So the model and database are all working fine. Now I am trying to bulk filling the database from a script. Based on the answers I found here I am doing it first filling the longitude and the latitude columns then by executing engine.execute("UPDATE listings_listing SET location = ST_SetSRID(ST_MakePoint(longitude,latitude), 4326)") from a python script. The query executes without exceptions and the database seems filled with proper values. Here few examples longitude, latitude, location -55.7385809,-34.7413717,"0101000020E6100000A279A5D189DE4BC008D79244E55E41C0" -56.1645314,-34.9011127,"0101000020E610000022156B5D0F154CC0504134A9577341C0" -56.4670779,-30.4264621,"0101000020E610000099976835C93B4CC0C57BC49E2C6D3EC0" -55.760207,-34.774156,"0101000020E61000005B9885764EE14BC04700378B176341C0" -56.2553815,-34.7901883,"0101000020E610000070404B57B0204CC04617E5E3246541C0" -55.760336,-34.773944,"0101000020E610000059FCA6B052E14BC0BC77D498106341C0" -57.0544726,-30.7552116,"0101000020E610000098C349F5F8864CC0518F238C55C13EC0" -56.4739006,-30.4097107,"0101000020E610000003475DC6A83C4CC03F52E9CCE2683EC0" Now when I try to make the first search by the nearest points i get GEOS_ERROR: ParseException: Unknown WKB type 337 and from the logs of django Error encountered checking Geometry returned from GEOS C function "GEOSWKBReader_read_r". I googled the error but nothing. I checked possible NULL values in longitude and latitudes, but they are all fine. I suspect that I am missing a step. Someone can point me in the right direction? -
how to generate unique id in factory using faker: Django
I am trying to insert data into my database (sqlLite3) using factory and faker. This is my model: class User(models.Model): id = models.CharField(max_length=9, primary_key=True) real_name = models.CharField(max_length=200) tz = models.CharField(max_length=200) Factory for the model: class UserFactory(factory.django.DjangoModelFactory): class Meta: model = User fake.add_provider(MyProvider) real_name = factory.Faker('name') id = ''.join(fake.random_letters(length=9)).upper() tz = fake.timezone() When I run UserFactory.create() for the first time, User is added but when I run the second time in the same python shell or try to run UserFactory.create_batch(5), it gives me the following error: django.db.utils.IntegrityError: UNIQUE constraint failed: activities_user.id If I run it in a different terminal or exit from shell and run the same command again it runs fine. Seems ''.join(fake.random_letters(length=9)).upper() always returns same value. Even though I have used random_letters I wonder why this is happening. I am new to using factory boy and faker. Please help me out on this. Let me know if I am missing anything. -
Django calling methods of DetailView and RedirectView in template
I'm trying to get into Django and got stuck with DeatailView and RedirectView I made the following template for rendering posts with enabling post detailed view and like button. When I click on either Like or Detail button none of the requests is sent. I tried changing different methods, but that didn't help either.
