I need help for implement a custom django login
I'm trying to develop a custom login in Django instead of using Django inbuilt login system. I don't know weather it's possible of not. If it's possible please help me to do this. I want to capture the value form the login template form. I have tried many ways but it's not working This is my backend code def login(request): if request.method == 'GET': context = '' return render(request, 'mytest/login.html', {'context': context}) elif request.method == 'POST': context = '' username = request.POST.get('username', '') password = request.POST.get('password', '') print(username) print(password) return render(request, 'mytest/login.html', {'context': context}) This is my login template <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post" action="{% url 'login' %}"> {% csrf_token %} <label>Email</label><input type="text" name="username" required><br> <label>Password</label><input type="password" name="password" required> <input type="submit" value="Login"> </form> </body> </html> please help me to get this work -
Django initial value for MultiChoice Field ignored for ModelForm
this is my first post here and I am very new to Django but I just can't seem to find a solution for this problem... I've searched stackoverflow and google but nothing seems to work for me... I have a wine-app and want to be able to add and remove wines from the user's stock. In the list of wines the user can choose a wine to add and the ID of this wine is passed in the POST data. Since the data is getting lost after the first time the view is rendered I saved the ID in a cookie, which is working, but the problem is when I work with ModelForm de user has to select the foreign key for the user and for the wine, which is bad, so I tried to make it hidden and set the Fk_user and Fk_wine after the user choose the number of bottles to be added but before validation. Here's the problem after google everyone suggested I should use the "initial" and pass that to the form, but this is clearly not working because if I make the fields visible in the form I can see that it is not preselected... … -

Django url regex hit end of url: *./something
I am geting 404 on different urls that end with the same string and instead of creating multiple redirects I would like to catch them all on the last string. It always appears at the same position, pattern goes like so: /some-of-my-urls/the-same-string No trailing slash there. I tried something like this: url(r'^[a-zA-Z0-9_]+/the-same-string', redirect_func), url(r'^./the-same-string', redirect_func), But that doesn't work. Probably obvious for somebody with more regex knowledge, I am not very advanced. Anybody ideas? -
Django: Secret Key in Production
What is the right way to keep the SECRET_KEY safe in production. I've seen people suggesting that load it from environment variable, but I have no idea what that is & how to load from it? I tried creating a separate new_settings.py file & stored the secret key in there. Like that, KEY = 'something' And then in original settings.py file, I did this, from new_settings import KEY SECRET_KEY = KEY But it's raising an error that, No module named 'base_settings'. So, what is the right way for setting this up? Thank You . . . -

How to integrate new payment gateways with django-payments?
I want to integrate payments for a personal Django project that I'm working on. Saleor uses django-payments for payment processing. Unfortunately, most of them don't work here in India. Cybersource does work but their transaction fees are a bit higher compared to the payment gateways from India. I'd like to implement something like Razorpay or Instamojo into django-payments such that I don't end up breaking Saleor in any way but I don't have the faintest idea on how to start. I clone the package and then what? I was suggested to use the "dummy" as reference to implement the functionality but I've got no idea on how to test if it even works. How should I go about that? I don't see any contributing guidelines as well. I don't mind contributing back to the repo as well. I just want someone to point me in the right direction and I will take it forward from there. Thank you! -
