Django, environment variables. Error: SMTPRecipientsRefused at /password_reset/
it's my first post here. I'm learning Django, and i'm trying to send an email to reset my password. There is one problem.. When I send an email with my username and password assigned to these constants, everything works well: EMAIL_HOST_USER = 'abc.def@gmail.com' EMAIL_HOST_PASSWORD = 'Abc123' But when i try to use environment variables instead: EMAIL_HOST_USER = os.environ.get('EMAIL_USER') EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_PASS') i got an error SMTPRecipientsRefused at /password_reset/ {'abc.def@gmail.com': (501, b': sender address must contain a domain')} Am I doing something wrong? Maybe I should use environment variables in different ways? In advance, thanks for your help, guys! -

Django graphql JWT authentication gives anonymous user although valid token is given
I'm following this tutorial on authentication with django-graphql-jwt. I'm failing at step Testing the Authentication. I get a valid token via ObtainJSONWebToken but when I insert this token into the HTTP header authorization and perform a query (me) that checks the user status it gives an anonymous user. When I am logged in via django admin page it works without any token. It seems like the middleware is not working properly but that is just a guess. Here my code and what I do: settings.py: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] GRAPHENE = { 'SCHEMA': 'schema.py', 'MIDDLEWARE': [ 'graphql_jwt.middleware.JSONWebTokenMiddleware' ] } schema.py class Query(teamorgaisation_queries.Query, users_queries.Query, graphene.ObjectType): # this class inherits multiple Queries as we add more apps with their own schema pass class Mutation(teamorganisation_mutations.Mutation, users_mutations.Mutation, graphene.ObjectType): token_auth = graphql_jwt.ObtainJSONWebToken.Field() verify_token = graphql_jwt.Verify.Field() refresh_token = graphql_jwt.Refresh.Field() me-query import graphene from django.contrib.auth.models import User from django.core.exceptions import ObjectDoesNotExist from voss_be_django.users.graphql.types import UserType class Query(graphene.ObjectType): me = graphene.Field(UserType) def resolve_me(self, info): user = info.context.user if user.is_anonymous: raise Exception('Not logged in!') return user Postman query without authorization header: mutation tokenAuth($username: String!, $password: String!){ tokenAuth(username: $username, password: $password){ token } } variables: { "username": "testUser", "password": "UserTest#1234" } response (inside … -
Django static url with digitalocean spaces
I have an droplet on digitalocean which for the most part is working great, however i have enabled the cdn option in digitalocean spaces (similar to aws s3 storage) and in trying to load static files using the cdn url, i cannot seem to get the url working correctly so suspect i am missing the obvious? For example when i change the STATIC_URL in settings to the cdn no change is seen in the web page source? If i change the AWS_S3_ENDPOINT_URL and MEDIA_ENDPOINT_URL then the source does change but the files are not found and as one can guess a collectstatic no longer works, So i assume that the AWS_S3_ENDPOINT_URL & MEDIA_ENDPOINT_URL need to remain as is and i merely need to ensure the static_url is used? I did read somewhere that it was not good practice to change the templates from {%static.... to {%static_url so have not done that, is this something i should update or not? Settings: AWS_S3_ENDPOINT_URL = 'https://nyc3.digitaloceanspaces.com' MEDIA_ENDPOINT_URL = 'https://nyc3.digitaloceanspaces.com/media/' AWS_STORAGE_BUCKET_NAME = 'mysitestaging' #STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' # if False it will create unique file names for every uploaded file AWS_S3_FILE_OVERWRITE = False STATICFILES_STORAGE = 'mysite.settings.storage_backends.StaticStorage' DEFAULT_FILE_STORAGE = 'mysite.settings.storage_backends.MediaStorage' AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } … -

Django Authentication - Page redirecting to home even it goes in to exception
I am doing Simple User Registration part of my project, using Django's User table. Which supposed to redirect to home page after successful user registration and its login only, but even though I am filling up duplicate (incorrect)entry for username, its going to home page instead of showing the error on Sign up page.

Change function to class view django
I'm doing a django app and at first I've done methods to my view, but I'd like now to change to class. Here's an exemple of how I tried : def register(response): if response.method == "POST": form = RegisterForm(response.POST) if form.is_valid(): form.save() return redirect("/login") else: form = RegisterForm() return render(response, "register/register.html", {"form":form}) And tried to change like this : class RegisterView(generic.View): def post(self, request): form = RegisterForm(response.POST) if form.is_valid(): form.save() return redirect("/login") else: form = RegisterForm() return render(response, "register/register.html", {"form":form}) But I keep getting a 405 Error Method not allowed, I guess it's because I'm not doing right the changing from method to class. Any idea ? -

Where is Django's own database?
This question asks where the Django installation is. This question is about the table django_migrations. I've looked under the path from the command django in the interactive console, where I find a subdirectory db, along with middleware, etc. But I've no idea where this table django_migrations (i.e. the data in it) is in fact kept. I want to know firstly because I want to know what happens if this data is lost. I'm just learning Django and I don't quite understand how much of a problem this would be. The path to the Django location is under a directory in my home folder where I keep my Python virtual environments, the name of which begins with a ".". I tend to exclude such directories from my backup plans... Having just deleted db.sqlite in my project I see that it gets regenerated when you do migrate, together with a list of (in my present case) some 15 migration operations. I'm quite mystified by some of these: the first 10 or so seem to have occurred before I started doing anything to my models.py file. Are they documented or explained somewhere? -
Managing timer based threads
I'll give some back story for context before the question. I'm currently creating a small Django based web site with some code on the back. This is basically a security scan website, so a Recon module is part of it. A user fills up a form and recon begins. Because many users can access the website at the same time, I handeled the call to recon method with threads, this way more than one user can actually use the website. Something like the following def recon_view(request): if request.method == 'POST': form = ReconForm(request.POST) if form.is_valid(): recon_thread = threading.Thread(name='Recon Process', target=recon.run_recon, args=(form,)) recon_thread.start() The next step is to implement some sort of monitoring mode, from what I have searched, one can use threads this way. threading.Timer(1, foo).start() The recon will run once a week or few days so time is not an issue. Would this be the correct approach? Woulnd't this mean that everytime the user starts a recon, the Thread will continue running basically until the server stops (Meaning possibly hundreds of threads at the same time). The other option I can think of is using a separate script that makes an API call to the website, triggering the recon -
Fetch modal data with Ajax from Django Model
Sorry for repeating this question, and Ajax integration since its very broad subject, but I just can't figure it out. I have a html table with 4k+ rows of data, and each of rows has some basic information like name, address, last name, phone, and a button which triggers a bootstrap modal which contains additional data like phone2, address 2, etc. My problem is, since my modal is located inside a for loop like this - <tbody> {% for opp in optika %} <tr> <td>{{ opp.example }}</td> <td>{{ opp.some_field }}</td> <td> <button id="testbtn" type="button" class="btn btn-success btn-sm btn-detail" data-toggle="modal" data-target="#detalji_modal{{ opp.pk }}" Detalji </button> </td> ... </tr> {% include "opportunity/partials/_detalji_modal.html" %} {% endfor %} </tbody> And this is modal detail - <div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" id="detalji_modal{{ opp.pk }}" aria-labelledby="detalji_modalLabel"> <div class="modal-dialog modal-lg" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="detalji_modalLabel">Detalji</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body" id=""> <div class="container-fluid"> <h5>{{ opp.... }}</h5> <p>{{ opp.....title }}</p> ... </div> </div> <div class="modal-footer"> <p style="margin-right: auto">Zahtev uneo/la : {{ opp.... }}</p> ... ... <button type="button" class="btn btn-outline-primary" data-dismiss="modal"> Close </button> </div> </div> </div> </div> I'll pass the view also : @login_required(login_url='registration/login') def OptikaList(request): user_groups = request.user.groups.all() … -

Django: How to iterate over form fields choices without knowing the fields name?
I have a form whose fields are created in its __init__method: class Form(forms.Form): def __init__(self, modelInstance, *args, **kwargs): super(Form, self).__init__(*args, **kwargs) # create fields based of modelInstance data (because it might change) self.fields[modelInstance.name] = models.ChoiceField(choices=SomeChoices, widget=forms.RadioSelect()) Therefore i can not know in advance how the field may be named. Now how can I iterate over the field choices without knowing its name? What I'd like: {% for field in form %} <p>sometext</p> {% for value, text in field.NAME.choices %} <input type="radio" name="{{ field.name }}" value="{{value}}" id="id_{{ field.name }}_{{forloop.counter0}}"> <label>{{text}}</label> </div> {% endfor %} {% endfor %} I know field.NAME only returns the actual field name and does not give me access to its choices. But how else can I do this? Any help is greatly appreciated! -

django.contrib.gis.geos.error.GEOSException: Could not parse version info string "3.7.1-CAPI-1.11.1 27a5e771"
Background of the problem: I'm working on a legacy project built on python 2 and Django 1.9. So a few days back I have set up this project and then my debian 10 OS got some problem I had to reinstall the OS but my project was saved and I am using the same env which was created before. I had this error before but I had no idea how it got fixed on its own now it's coming up again. So the research and based on the recent workout the only lead I got buy some StackOverflow fellow have is According to old docs for 1.10 (1.9 docs aren't available). Django 1.9 only supported GEOS 3.4 and 3 docs.djangoproject.com/en/1.10/ref/contrib/gis/install/geolibs. You'll have to install the older version of GEOS or upgrade Django Now the link provided has few lib to be installed, I have done that but still getting this error when I run python manage.py migrate I'm still getting this error: Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/home/rehman/projects/comparedjs/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line utility.execute() File "/home/rehman/projects/comparedjs/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 327, in execute django.setup() File "/home/rehman/projects/comparedjs/local/lib/python2.7/site-packages/django/__init__.py", line 18, in setup apps.populate(settings.INSTALLED_APPS) File "/home/rehman/projects/comparedjs/local/lib/python2.7/site-packages/django/apps/registry.py", line 115, in … -
How to get started with DJ-stripe?
For what I can see Dj-stripe seems to be a very active project. However, the documentation is lacking so many details, tutorials, etc., that for me it has been easier to re-create the wheel than using the library. How do I get started? How do I, for example, save credit card details to a customer? How to use Connect? I am sorry I am so not specific. Nevertheless, there are so many open questions is impossible to list them all. -
