Getting Server Error (500) on django herokuapp while sending email from gmail SMTP
I have created a Django app and deployed on to Heroku. I have a view which sends invitation to a new person. Everything is working fine on the local machine.

Python strptime not parsing data from imported CSV
I am attempting to import a CSV with lines that include a "created_at" date. I am getting circular errors. The date string I am currently attempting to import is '2020-05-14 16:10:21.360520+00:00' which is on line[2] in my csv file. Here is the code that I am attempting to use: for line in import_csv: if line: import_data = BlogLink() created_at = line[2].split('.') import_data.created_at = datetime.datetime.strptime(created_at[0], "YYYY-MM-DD HH:MM:SS") this gives me the error: time data '2020-05-14 16:10:21' does not match format 'YYYY-MM-DD HH:MM:SS' My alternate for this code is this: for line in import_csv: if line: import_data = BlogLink() created_at = line[2].split('.') import_data.created_at = datetime.datetime.strptime(created_at[0], "%Y-%m-%d %H:%M:%S") This gives me the error: time data '' does not match format '%Y-%m-%d %H:%M:%S' (ie it does not even attempt to include the time data). What am I doing wrong here? -
django-leaflet + leaflet-rastercoord (macOS 10.13.6 + homebrew)
I am working on a postgres based django project to create floor plans. I have experience in python3 but js is new to me. I need this to be running in very basic functionality in the next 6 days. So yes: My sweat turned acid. The goal is pretty damn simple: Floor plan with updating overlays (e.g. blue rectangle marks free storage etc). What I need: Floor plan as base-map rectangular (updating) overlays markers Django-leaflet works fine, but rastercoord is killing me. I simply tried to implement the demo code into my template html and it seems like it just silently fails to execute. Django-leaflet itself works like a charm, markers are displayed and so on. I modified the original example code to use my tiled milkyway image from wikipedia, which works just fine. /* * @copyright 2015 commenthol * @license MIT */ /* global L */ ;(function (window) { function init (mapid) { var minZoom = 0 var maxZoom = 5 var img = [ 6000, // original width of image `karta.jpg` 3000 // original height of image ] // create the map var map = L.map(mapid, { minZoom: minZoom, maxZoom: maxZoom }) // assign map and image dimensions … -

Django login with Allauth and an extended customer user model doesn’t seem to allow for email and password login
Hey guys so basically I’m implementing a custom user model extending from AbstractUser. I am also using Allauth. In previous practice projects I have built I am able to configure Allauth so that I can register new users and login in with only an email and password. This however is implemented without actually extending my user model(I just created the class and the passed). When I do then add custom fields for my users with my current project, and after reading the docs for Allauth about custom user models, I loose that functionality. I have to login with a username. What I would like is to have my login how it works when you don’t extend the user model. Meaning that you can register and login in with you email and password. I have tried all the combinations I can think of using the settings in Allauth docs. I just cant seem to figure it out. Has anyone had a similar experience or just know perhaps what im doing wrong? -

Linking two models in django automatically
I have a problem with trying to link two models together in a Django project. I have two models, Songs and Albums where the Song must be linked to an album using a Foreign-Key-Field. Adding an album works perfectly and each album has a different primary key, the way a user of my website adds a song is by going onto the album page (called detail.html) where there is a button saying 'add song' that takes the user to a forum to add the song. Currently if I add in a Foreign Key Field into the song model it allows the user to choose any album to add the song into which I do not want, I would like the song to be automatically linked to the album with the primary key of the album on the detail. Please help if you can and if anything does not make sense or you need some of the code pease reply and let me know. Thank You. -

How to store many Linear Regression models in django?
I am trying to build a Django app where a user can upload a CSV file and a sklearn linear model will be created and trained to that dataset. So, each time a new CSV file is uploaded a new model will be created. My question is what options do i have for storing these generated models in Django so that users could later choose which model they wanted to use? I have seen some suggestions for pickling them using cpickle and also using Django's cache framework, how would these options affect performance? -
Django cookies and database storage at same time using forms. One of them does not work when the other does
I'm new to django and webdev as a whole, iam trying to submit data into a form and at the same time store it in a cookie and redirect to the next page using action attribute. index.html does not redirect on submit unless and until it uses action='datetime' in form tag and when it does not redirect it Stores the value in sqlite3 DB but when it does redirect it stores the name in cookie but not in the DB. at one point i got an error when the url set in path for datetime.html was path('datetime/', views.dateTime) error:You called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH set. Django can't redirect to the slash URL while maintaining POST data. Change your form to point to 127.0.0.1:8000/datetime/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings. but that was resolved when i set it to path('datetime', views.dateTime) index.html <!DOCTYPE html> {% extends './base.html' %} {% block body_block %} <h1>LoginForm</h1> <form method='post' > {{ form.as_p }} {% csrf_token %} <button type='submit'> Submit</button> {% comment %} <input type="submit" value="submit" /> {% endcomment %} <!--tried using href="datetime/" in button as well both did … -

Django Pagination with Django-Filter
Hello Django community. I am at a complete loss as to why pagination is not working for me, as I am not getting any errors, and only certain aspects of it aren't working. I am using a function based view, and am also filtering my queryset with Django-Filter. I know that the page_obj is being passed through the context, and is a django pagination object, because the conditions which require it in the template are passing. (the links for page1, page2, next page, last page, etc.. populate). What isn't happening, is that it is not actually paginating. The buttons appear, and a pagination object is passed, however the full queryset still appears on page 1, and if I click on page 2, 3, or whatever, it is the same exact queryset. I have tried playing around with what I pass as the object_list to the paginator, as well as removing the django-filter object, and playing around with the object_list again. Really confused as this seems like I'm doing something obviously wrong but I've been stuck on it long enough to resort to asking for help. Thanks in advance. views.py def home(request): reports = Report.objects.all().order_by('-date') # Instantiating the filter myFilter = … -

Execute a Go script from Django webapp safely
How do you launch a Go script in a django app safely? I made a go script which is self contained. I would like to be able to launch a job from a django web app (I use celery to have the job run in the background). What would be the proper/safer way of achieving this? Maybe a way to isolate this process? I feel that running... os.system(f"./goscript -o {option1} -b {optiom2}") ...is quite unsafe. as a bonus, I'd like to be able to get the output to see if the script crashes etc... but that is a bonus question. -
Nginx cannot serve backend's static files
Nginx is set up with both frontend and backend services in Docker - both are working without any issues apart from backend static files which are not being served by nginx (http://api.example.com/static/...). Since frontend is SPA and consists of static files already - they have no issues being served from within nginx container. However, nginx is not serving backend static files. The static files are definitely in the nginx container (/home/app/web/static/) - however nginx is giving the following error when checked in the console - this is probably because the CSS file below would return 404 (which is html page) - hence it cannot apply html to CSS . Nginx log files are clear. Refused to apply style from http://api.example.com/static/admin/css/responsive.css because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. P.S. Backend framework is Django whereas Frontend is Vue. nginx.conf file upstream api { server backend:8000; } server { listen 80; server_name example.com; root /usr/share/nginx/html; index index.html index.htm; # frontend location / { try_files $uri $uri/ /index.html; } location @rewrites { rewrite ^(.+)$ /index.html last; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } } server { … -

How to use default value in Django model once set to null?
I have this model in my django app: class Person(models.Model): name = models.CharField(max_length=50) image = models.ImageField(blank=True, upload_to='images', default='default/static/image/here') def __str__(self): return self.name When making a Person object, if left empty, the "image" is set to a default value, but later, if the user decides to remove his image, his image will no longer be set to default but to NULL instead. How can I make it so that whenever image is NULL again, it automatically brings back the default value?
