How to determine if I am currently inside a Redis Task Worker
if i have a function def I_TAKE_A_LONG_TIME(): if I_AM_RUNNING_IN_A_REDIS_WORKER: # do something special # do some stuff that takes a while from rq.job import Job @Job('default') def worker(): return I_TAKE_A_LONG_TIME() sometimes this is called directly, I_TAKE_A_LONG_TIME() other times it is called via worker.delay() (redis task stuff) is there a builtin redis way to tell if I_TAKE_A_LONG_TIME is being run in a task worker vs being run directly? get_current_job() I think returns any the current running job (not necessarily this running job) -

Klaviyo Form shows twice on homepage
I embedded a klaviyo form on shopify and it showed twice on the homepage of the shop I'm working on.

Adding a Sold Out option to price field in Django
at present I have a basic shop with a price model defined as a decimal field. price = models.DecimalField(max_digits=10, decimal_places=2) I'd like to be able to keep products visible but add a sold out option. Is there a way to allow this field to include a blank price or a Sold Out option? I had also tried adding another model field that would be tested for truth and displaying sold out otherwise, but this didn't end up showing in template. Here, my idea was: soldout = models.BooleanField(defualt = False) and in the template: {% if product.soldout %} <button type="button" class="btn btn-danger">SOLD OUT!</button> Thanks! -

How to fix reverse-matching URL error in Django?
I'm making a blog app using Django. The error appears when I click on save button on a new post and the 'Post-Detail' page is not just showing up.

How do I get a background color to fill the entire page and fade into a picture with an svg on top?
I created a grey color background so I could overlay it on top of a picture I currently have. The picture is in a urls.py file and is passed as the background. I want the grey to fade into a picture but the grey background isn't covering up the entire screen just some of it. I know it has to do with the padding and margins probably but I am pretty new to html and css. I also have an animation I made with an svg I want to be on top of the grey background. It is doing the fading part but after 10 seconds the grey color comes back and doesn't disappear. I am also using my django server as my backend to run the website. I have tried making the margins and padding 0 which didn't work and also varying the numbers on the margins and padding which doesn't make it fill the whole website.

I've stuck on this for days now gunicorn is using the old virtual environment even after unistalling it and deleting the directory?
I deployed a Django project on an ubuntu server using gunicorn and Nginx but I had to delete the project and use a new Github repo and set a new virtual env so I deleted the virtual env and deleted gunicorn.config and removed and installed Nginx and tried deploying the app it started giving weird errors and finally no when I ran sudo journalctl -u gunicorn i found that it still refers to the old env and gives a file not found error. How can I reset it correctly? -
Django null value in column "project_id" violates not-null constraint
So I can see why this is happening, the page is not linking to the project I am trying to update, but I don't know how this is done, I thought that was what "get_object" method was for, but I'm clearly not using it properly. I can get this working if I uncomment "project" in the form which lets me choose which project I am attempting to update from a dropdown, however, I would like to do away with that field and have the update dynamically linked to the project.

Child class post method to return different template and context
I want to be able to take the same form input and use it to do calculations (using different urls) for different products and send product results to a product template I tried having a base class with get and post methods from which child classes(different product urls) will inherit especially the post method to remain DRY from .models import InputForm class InputView(TemplateView): template_name = 'input.html' def get(self, request, *args, **kwargs): form = InputForm() return render(request, self.template_name, {'form': form}) def post(self, request, *args, **kwargs): form = InputForm(request.POST) if form.is_valid(): self.cleaned_data = form.cleaned_data a =cleaned_data['mbr_l'] b =cleaned_data['es_l'] c =cleaned_data['wic_l'] d =cleaned_data['br2_l'] length = a + b + c + d qty = 0.8*length return render(request, 'result.html', {'qty': qty}) else: return render(request, self.template_name, {'form': form}) class B(InputView): def post(self, request, *args, **kwargs): qty2 = super().post(self, request, *args, **kwargs) return super().render(request, 'result2.html', {'qty2': qty2}) I expect the url B in url conf to do calculation and send context(qty2) to results2.html but it always renders results.html with qty which is correct because B is inheriting InputView and all methods. -
ManyToOneRel field for Following functionality?
I read this question thread ( Difference between ManyToOneRel and ForeignKey? ) and I'm not understanding it completely. I need a many to one relationship so I can add in following functionality. Tried with a many to many and that makes two users follow each other even when one didn't want to (if one user clicks 'follow' then it acts as though the other did the same.) Question is, will I need to use a ManyToOneRel field for the followers (who follows the logged in user) and the same for who the user is following? Forgive me, I'm teaching myself everything and some stuff can be difficult to grasp at times. -

Django login() doesn't persist after HttpResponseRedirect
I have custom Django login forms that, since upgrading from Django 1.8 to 2.2, no longer keep user logged in after HttpResponseRedirect. Here's is a generalized sample of the code: @render_with('users/login.html') def login_view(request, campaign_id=None): if request.method == 'POST': form = LoginForm(request.POST) if form.is_valid(): email = form.cleaned_data['email'] password = form.cleaned_data['password'] # Login user user = authenticate(request, email=email, password=password) if user: if user.is_active: login(request, user) return HttpResponseRedirect('/redirect-user/') I know that login() is working properly because if I use render instead of HttpResponseRedirect, the user is logged in. However, I want to redirect the user to a different view after login. What is the best way to do this? -
From views, how do I pass both context and registration form to my registration template?
I'm fairly new to Django and I'm trying to pass both the context and my registration form. I know how to pass either the context, or the form, but not both.

I have no experience in web app development, but I want to make a project like the following: My school dorm requires you to make a leave request online on Monday in order to leave the dorm on the weekends. My friends and I always forget to do this. I want to make a web app that basically if the user inputs their information, it would automatically make a leave request every Monday for that user. I have a leave request script written, and I'm sure I can figure out how to make a website and store user data in the database. My question is, is it possible in a Django web app to schedule a script to run once every week? I'm planning on deploying to Heroku, would I have to schedule it in Heroku or Django? If this isn't possible in Django, what would I use in order to go about implementing it? I'm sorry for such a vague question, I'm just not sure where to start and I'm very new to web app development. Any help is appreciated!
