Filter and get values using OR and AND conditions in Django
I am querying a set of objects with a condition like this: for filter_for_dates_report in filters_for_dates_report: filter_dict.update({filter_for_dates_report: { filter_for_dates_report + "__range" : [start_date, end_date] }}) list_of_Q = [Q(**{key: val}) for key, val in filter_dict.items()] if list_of_Q: model_details = Model.objects.filter(reduce(operator.or_, list_of_Q)) .values(*values_list_for_dates_report) Now I want to exclude the objects which have null values for filter_for_dates_report attributes. A direct query would be Model.objects.filter( Q(filter_for_dates_report__range=[start_date, end_date] & filter_for_dates_report__isnull=False)) .values(*values_list_for_dates_report) But how can I do this for multiple values wherein I want only the values within that range and also which are not null for multiple filter_for_dates_report attributes. Something like: Model.objects.filter( Q(filter_for_dates_report__range=[start_date, end_date] & filter_for_dates_report__isnull=False) | Q(filter_for_dates_report__range=[start_date, end_date] & filter_for_dates_report__isnull=False) | Q(filter_for_dates_report__range=[start_date, end_date] & filter_for_dates_report__isnull=False) .values(*values_list_for_dates_report) -

What is the most efficient way to compare a string to Enums?
I have the following Enum class: class LabelEnum(str, Enum): ENUM_ONE = "Enum One" ENUM_TWO = "Enum Two" ENUM_THREE = "Enum Three" FOUR = "FOUR" FIVE = "FIVE" SIX = "SIX" I want to compare a string with all of the members of this enum and see if the string exists in the enum class or not. I can do this by following snippet: if string in LabelEnum.__members__: pass But I want to compare the lower case of the string (string.lower()) with the lower case of the enum members. I can't do this in the above way I think. Another way is to loop through the members but that will slow the execution and I don't want that. Is there any way I can compare the lowercase of these in a single line and more efficiently than looping? -

Django: Unexpected keyword error when trying to create with correct parameters
I'm just starting out in Django and following along with a tutorial. I've copied exactly what they did, but I'm still getting this unexplained error. For this particular app, my very simple models.py file looks like this: from django.db import models # Create your models here. class Product(models.Model): title = models.TextField description = models.TextField price = models.TextField summary = models.TextField(default='This is cool!') I can't see anything wrong with the code, but when I use the Python shell and write Product.objects.create(title="test", description = "test2", price = "test3", summary = "test4"), it throws the error TypeError: Product() got an unexpected keyword argument 'title'. What am I missing? Is there a deeper problem here? -

Sending an email from python django app with azure logic apps
I followed this tutorial to deploy a basic python django app to azure app service. The full code for the app can be found here. This works fine, its a basic polling app where I can add questions and visitors can answer the poll questions and I can monitor the results. I then tried to follow this tutorial to create a logic app that will send an email when a poll question is answered. The logic app seems to have been created successfully. At the end of this tutorial there is a short section on integrating this logic app with my django app by adding an HTTP post into the code. However, the section of code it tells me to put it in is in a non python file that doesn't exist in the provided repo. It seems to be some sort of mistake. So basically I'm not sure where to put the HTTP post in my django app. I've been reading through the django docs to try to better understand what the example app code is doing exactly but I feel like I'm in a bit over my head at this point. The azure tutorials were pretty explicit about … -
Django admin not being updated by custom method
I have a meta-model that stores website information. Model Code class MetaModel(models.Model): name = models.CharField(max_length=4) students = models.IntegerField(default=0) instructors = models.IntegerField(default=0) courses = models.IntegerField(default=0) transactions = models.IntegerField(default=0) cashins = models.IntegerField(default=0) cashouts = models.IntegerField(default=0) balance = models.IntegerField(default=0) There are some other models like Students, Instructors, Transactions etc. So I am using a custom method that will update meta info automatically def update_meta(self): self.students = StudentModel.objects.count() self.instructors = InstructorModel.objects.count() self.courses = CourseModel.objects.count() self.transactions = CourseModel.objects.count() self.cashins = CashinModel.objects.count() self.cashouts = CashoutModel.objects.count() The index view looks somewhat like this def index(request): f = MetaModel.objects.first() f.update_meta() return render(request, "app/index.html", {'meta':f}) The index page gets updated everytime and shows me the info correctly. But when I go to the django admin page, the data are not updated. Image attached for clarity How do I fix this? -

How to let Django see files under dist/static generated by Vue.js compilation?
I'd like to know how to specify static directory for Django in the following case. I don't use Django template at all (I don't use {% static ... %} in html file). vue-cli generates outputs under dist/, which is not in the scope of Django project, and I don't like to change this.

Python Django: Filter within for loops
Context I currently have 'Building' and 'Room' objects stored in my database - linked by a Foreign Key. I'm trying to generate a Room query set for each Building using for loops and objects.filter() Problem See the code posted below - I can't seem to solve a seemingly simple problem. 'BuildingList' returns two objects, but for some reason my for loop only queries and appends a 'RoomList' for one of two buildings. (The second one) I don't understand why, but RoomList = Room_Data.objects.filter(Room_Building=b) seems to disrupt the logic and flow of my basic for loop. Python Script: # # # 1.) GET DATA FOR RELEVANT SET OF BUILDINGS FusionBuildingName = "Renal Dialysis Unit x6" BuildingRoomLists = [] # GET DATA FOR ALL BUILDINGS MATCHING 'FusionBuildingName' BuildingList = Building_Data.objects.filter(Building_Name=FusionBuildingName) print(len(BuildingList)) print(BuildingList) # GENERATE BUILDING ROOM LISTS for b in BuildingList: print(b) print("Building Author: " + b.Building_Author) print("Building Room List:") # GET LIST OF ROOM OBJECTS FOR CURRENT BUILDING RoomList = Room_Data.objects.filter(Room_Building=b) print(str(RoomList)) # APPEND LIST OF ROOM OBJECTS TO BUILDING ROOM LIST BuildingRoomLists.append(RoomList) Below is what my Python Shell returns upon running the above code: In [43]: In [44]: ...: ...: ...: ...: ...: ...: ...: Building_Data object (1) 1 Building … -

Looking for expert advice on programming language
I know this question is a bit unorthodox for this type of site, and I will probably hear some feedback to reinforce that - but I also have used this site many (many) time sin the past to solve coding issues so i know there are some high-level experts here who are kind and helpful. With that said - I have been a front-end designer for about 10 years. I primarily use Wordpress and Bootstrap for developing customer websites. Reasons for this are simple - it is a quick, all in one solution that can be customized according to any taste, and can be made secure with enough attention to detail. I learned to be proficient at Adobe AE, PP, PS, AI, etc. I am 43 years old. I have been able to work form home developing small to medium sized client websites, graphics, video production, etc for the last 12 years. Before that I was an auto mechanic. I got in the game late in life. I have noticed the world of webdev has passed me by considerably.

Avoid race condition inside values of JSONField

Django Python how to take data from another sessionid cookie?
So I'm working with django python, and on every new browser I get a new sessionid for my cookie, every sessionid got a unique session database itself. I'm looking for a way to grab data from other sessionid's if possible. Example: Im on my site, in 2 different browsers. Each browser got a unique sessionid cookie, therefore a unique session database. (cookie examples (not real or valid)): Chrome: a7363dc Firefox: a3621bcz In chrome, I got request.session["foo"] Set too "bar" In Firebox, I got request.session["foo"] set too "zoo" Is there a way I can like var = request.session[a3621bcz]['foo'] so it takes the value of session "foo" in firefox? (lets say i perform this in chrome) Or alternatively, is there any way I can make every sessionid cookie the same all the time for everybody? so that everyone has the same access to the request.session["elm"] elements? Like example: wether im on chrome, firefox, or even at starbucks on my chromebook, when I search for the request.session['foo'] it returns "bar" no matter which one im logging in from?
