Python and Django Source Code Navigation in Emacs
I am wondering if there is a way to to navigate Python(Django) code in Emacs similar to how one can M-. for Common Lisp code when using SLIME. I have installed ELPY and a mode called python-django. However, they do not seem to provide this functionality. I am particularly interested in doing this why developing using Django. However, even navigation for standalone Python projects would be nice. -

Getting an error when doing get_or_create in MYSQL db?
I have a Django app, using an AWS RDS MYSQL instance. Below is from my settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'mydb', 'USER': 'username', 'PASSWORD': 'somepass', 'HOST': 'mydb.XXXXXXXX.us-east-2.rds.amazonaws.com', 'PORT': '3306', 'OPTIONS': {'init_command': "SET sql_mode='STRICT_TRANS_TABLES'; \ SET SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED",}, } } Below is the code that causes the issue for i in data: poll, created = Poll.objects.get_or_create(topic=i['topic'], question=i['question']) I am not sure what the error is, but this is offending line. Commenting it out causes the app to run. The error in get_or_create is resulting in a 500 error in the backend call that contains this code. I have rebooted the RDS instance since changing OPTIONS in DATABASES, and that did not help. -
Continuing Django-haystack filters on pagination
I'm trying to set up pagination within my Django project but I can't find a way to make the filters (ptags in my case) follow to the next pages.

Django: Update method creates a new image instead or replacing the actual image

TemplateDoesNotExist error after deleting folder
I originally created a login page at myproject/templates/registration/login.html. I'm very new to Django, I thought I could create multiple folders within the template file, but I ran into issues trying to do so. So, I deleted the registration folder and put ALL of the templates in myproject/templates. However, now, no matter what I do, when I try to go to login.html, I get the TemplateDoesNotExist area because Django is still trying to go to registration/login.html. How do I get it to stop doing this? I do not want to add the registration folder back unless I can do multiple folders in templates. I tried having all the templates in myproject/templates to no avail. I tried myproject/myapp/templates/login.html and that doesn't work either. I tried deleting and recreating the file as well.

Copying Django Templates from an App to Main Project
I am currently building a site in which I will use several 3rd party apps among which is the aldryn_forms. To make it work successfully, I need to edit some templates. It appears that to do so, I better copy the app's templates into the main project's /templates/ directory. This way, it will override the new templates whenever I move the code to the server and re-install the apps using pip install -r requirements.txt. Is my thinking here correct? Is this a good practice that in-line with best practice for Django development? Are there some examples where this may not be a good idea? -

sending email from Django view
I have a web app for ordering parts and I want to include an email when the user orders a part. I am having trouble adding the email function to my function based view. I have an existing function for saving the order form data and I wanted to simply add the email function to the same view. When I try to add it directly I keep getting error messages about inconsistent white space. So I created a new email function just below the new order view but I don't know how to pass some parameters from one function to the other. This is close but when I call the New_Order function it throws an error for order_instance not defined. Views.py @login_required def New_Order(request): if request.user.userprofile.shipment_access: if request.method == 'POST': form = OrderForm(request.POST) if form.is_valid(): order_instance = form.save(commit=True) order_instance.save() return Order_Email() else: form = OrderForm() return render(request, 'app/New_Order.html', {'form': form}) else: raise PermissionDenied def Order_Email(): subject = "Part Order" + order_instance.id orderNum = order_instance.id from_email = settings.EMAIL_HOST_USER to_email = ['dummyemail@gmail.com'] message = order_instance send_mail(subject=subject, from_email=from_email, recipient_list=to_email, message=message, fail_silently=False) return HttpResponseRedirect('/Orders') I'm ok with either one combined function or with two functions and passing the parameters from one to the next. … -

Placeholder in Django for login AuthenticationForm doesn't show up

How to keep a document available for x time in a website?
I am trying to show a report for 1 hour for everyone to view it. After that I want to show the next document available for 1 hour again. The problem is 2 employees can upload the reports at the same time. which means i have to create a queue? If I show the first one after an hour it should go to the other one. But I can see the problem of 2 reports at the same timestamp. meaning that when I return the reports that has a timestamp within the last hour reports with the same timestamp will not appear. -

Cookies when using separate Dyno for react frontend and Django backend
I am building a simple web app using React.js for the frontend and Django for the server side. Thus frontend.herokuapp.com and backend.herokuapp.com. When I attempt to make calls to my API through the react app the cookie that was received from the API is not sent with the requests. I had expected that I would be able to support this configuration without having to do anything special since all server-side requests would (I thought) be made by the JS client app directly to the backend process with their authentication cookies attached. In an attempt to find a solution that I thought would work I attempted to set SESSION_COOKIE_DOMAIN = "herokuapp.com" Which while less than ideal (as herokuapp.com is a vast domain) in Production would seem to be quite safe as they would then be on api.myapp.com and www.myapp.com. However, with this value set in settings.py I get an AuthStateMissing when hitting my /oauth/complete/linkedin-oauth2/ endpoint. Searching google for AuthStateMissing SESSION_COOKIE_DOMAIN yields one solitary result which implies that the issue was reported as a bug in Django social auth and has since been closed without further commentary. Any light anyone could throw would be very much appreciated.
