How do I send all form data from one view to another with sessions in Django
So I already know how to send and receive one value from InputWebView to DisplayWebView but I need to send all values from my form and receive it on the other side to process further.

Correct way to read data for a graph
What i want to do is to show some data in a graph. the data is from a pandas data frame that i generated in my main.py file when crunching some numbers. Now i want to show this in a chartsJS graph in another html. Is the correct way to leave my data frame that i generated in my main.py file and generate the graph by looking at the main.py file an reading the data frame. or is the correct way to generate a django model and have the graph read the data from a django model? The data frame will change everyday, hence the graph will be changing daily. If the latter is correct could someone show me how they would make the model if the data frame is just some text with numbers print(df["my_data"]) pass: 20 fail: 50 n/a: 8 -

Separate two forms' values in django
I'm working on an ecommerce website. Currently, I'm trying to add variations for products. Variations are dynamic. For adding products to the cart I have two forms, one for general details of the product, and the other for the variations. The problem is when I add a product with specific variations I can't separate these two forms' values from each other. The post request's data is like this --> <QueryDict: {'quantity': ['1'], 'override': ['False'], 'Color': ['1'], 'Size': ['3']]}> As I said color and size are dynamic and it could be more variations, and these are variation items so if I could change post request data to be like this --> {'variations': [1, 3]} it could solve the problem. # forms.py class VariationForm(forms.Form): def __init__(self, variation_fields, *args, **kwargs): super(VariationForm, self).__init__(*args, **kwargs) for field in variation_fields: self.fields[field.name] = forms.ModelChoiceField( queryset=field.item_variations.all()) # views.py @require_POST def cart_add(request, product_id): cart = Cart(request) product = get_object_or_404(Product, id=product_id) form = CartAddProductForm(request.POST) # Variation form should come here if form.is_valid(): cd = form.cleaned_data cart.add( product=product, quantity=cd['quantity'], override_quantity=cd['override'], ) return redirect('cart:cart_detail') -

How to use django_crontab with os.environ['SECRET_KEY']?
I'm using a django_crontab library and it worked fine until I decided to export my SECRET_KEY to an environmental variable.

Splitting a monolith file Django
First to set the scene a little. I am working on piece of software that has been worked on by a number of developers over the years, each making improvements, and compromises along the way. We have about 30 apps in the project, but about 60% of all of the code is in one models file. In recent years we have been moving away from this monolithic architecture, but we have not had the time/willingness to actually spilt this file up. It is causing issues just loading and searching the file at the moment. I am looking for any advice or strategies that could help with this. I have been looking into three methods/paths, but I am not sure if they are a good idea, or if there is a better one. Moving Models out 1-by-1. Hard code in the database name, and then overwrite the migration so no data is deleted, and move out each model one by one to their new home. Make the file into a directory. Instead of being one file, split this up into a number of files. This will alleviate the current issues we are having with the file size. And will also spilt … -
