Stuck at the start lerning Django
Sorry for mistakes, this text transleted by Google Translate Hi all! My story is short: I'm 21, I studied computer science, Python and algorithmization, basic sql, a little Git for 3 months. I am a 3rd grade university student. I started learning django and got stuck. The library turned out to be a stone wall that I pick with a wooden stick. knowledge does not fit in the head. I went through 5 of the 7 steps of the documentation tutorial. They say, start writing small programs, or catch up with tons of theory, or buy a course) But what to write when, at the start of writing, there is a fog in my head. I have of course ideas for pet-projects but they are hard to realize for me) I have been standing still for 2 months and it seems that I have already lost the knowledge gained in the tutorial I thought of copy-pasting a project on tutorials from YouTube, but some people told me that you won’t remember anything, that is why this idea died at the start) advice me something! -

In my app I use auth0 to do authentication. Everything works great, I can see new users being created in admin panel etc, but there is one issue. when I go to my endpoint that displays data I have an empty list.

How to send to print an ajax response in django
I'm trying to print (the action of sending to printer) a png image I get as a response from my ajax call. The reply from ajax is successful, meaning the image is properly sent. I can even open it in another window. However, I want to send that image automatically to print. I can do window.print() but that just prints the current page, not the response (obviously). Does anyone know how to process the response in order to print it? function traer_1234(){ $.ajax({ dataType: "html", contentType: "application/json", type: 'GET', data: {"nanda": 1}, url: "{% url 'View_test' %}", success: function (response) { alert("1234") window.print() }, error: function (response) { alert("Error") } }) } Thanks in advance to anyone who can supply any info. -

How multiply and sum two columns in different tables in django
I have an application for calculating diets based on the nutrients of each meal. In admin of this application I want to price of each meal to the Meal table, which I have managed to do by calculating the price when displaying it in admin: # admin.py class AdminMeal(admin.ModelAdmin): list_display = ['name', 'meal_type_names', 'price'] @admin.display(description='Price') def price(self, obj): unit_prices = np.asarray(obj.mealingredient_set.order_by('id').values_list('ingredient__unit_price')) amounts = np.asarray(obj.mealingredient_set.order_by('id').values_list('amount')) to_return = float(np.matmul(np.transpose(unit_prices), amounts) / 1000) return mark_safe(to_return) Now my main question: I need to allow ordering of Meal table based on Price which I don't know how. based on my search it seems I should use annotate instead of my current way of calculating the price to be able to sort my table, I found a solution in here # admin.py class AdminMeal(admin.ModelAdmin): list_display = ['name', 'meal_type_names', 'price'] def get_queryset(self, request): queryset = super().get_queryset(request) queryset = queryset.annotate(_price=Sum('mealingredient__amount * mealingredient__ingredient__unit_price')) But sadly it throws this error (I think it's because i'm trying to SUM over different tables): Unsupported lookup 'amount * mealingredient' for AutoField or join on the field not permitted. Any help is appreciated, forgive me if I have missed something obvious, I'm a beginner in django. Some of the relevant Models for Meal table: … -

How to add new field to a table in django that have "managed=False" because it was generated using inspectdb tool
I'm using an existing mysql database in a new django project, so I generated the models using inspectdb tool.
