Issue sending keys, values to django Q()
I am trying to filter some IDs using a django query and trying to do it efficiently, I want to get the same result I got from a less efficient function I created before, but I am getting an issue with the dictionary key using Q from tmd import models from django.db.models import Q category = { "utility": models.Account.UTILITY, "system": models.Account.SYSTEM } country = { "Guatemala": models.Country.objects.get(name='USA'), "Honduras": models.Country.objects.get(name='CA'), } def get_a(stage=None, **kwargs): base_args =[] base_args.append(Q(stage__in=stage)) for key, value in kwargs.items(): base_args.append(Q(key= value)) a_ids = models.Account.objects.filter(*base_args).values_list('id', flat=True) print("Number of a_ids: {}".format(a_ids.count())) return a_ids input: a_ids = get_a(country=country["USA"], category=category["utility"]) The issue is located exactly in this line: base_args.append(Q(key= value)) If I can make an input that changes the key for every iteration, this will be solved -
Automatically increasing the value of a variable in generate_series
I ran into the need to automatically increment the value of a variable in generate_series. By the condition of the business logic, the field identifier in the model does not increase automatically. I decided to try to find the maximum id value in advance and, within the of the generation, try to simply increase it by 1. But I don't understand how to do this correct. max_id = Companies.objects.aggregate(Max('id')) # {'id__max': 1529367} value = max_id['id__max'] cursor.execute(f''' INSERT INTO test.companies( id, name, city_id, revenue, labors ) SELECT {value} = {value}+1, # This is what I want, but I don't know how to do it ( SELECT x[1 + ((random() * 25)::INT) % 3] FROM ( SELECT '{{Google,Yandex,Amazon}}'::text[] ) AS z2(x) WHERE SEQ = SEQ ), (random() * 3000)::INT, (random() * 3000)::INT, (random() * 3000)::INT FROM generate_series(1,10) SEQ; ''') All this I do as part of my work for Python Django. -

django - disable Invitation object creation if User object with the email exists
I'd like to make sure that nobody can't create an Invitation object with an email that is already in a database either as Invitation.email or as User.email. To disallow creating Invitation with existing Invitation.email is easy: class Invitation(..): email = ...unique=True) Is it also possible to check for the email in User table? I want to do this on a database or model level instead of checking it in serializer, forms etc.. I was thinking about UniqueConstraint but I don't know how to make the User.objects.filter(email=email).exists() lookup there. -

I was developing a social-media/eCommerce web app with Django. I want to add a payment gateway for purchasing products on the website for that I am using 'Razorpay'. I integrated it which worked fine with my app. But I wanted to store the transaction-related details in a model called 'TransactionDetails'.

Need help writing tests - Django framework
I am relatively new to Python with Django, and very new to writing tests. The app I'm working with allows a teacher to assign multiple assignments to a student. On the student dashboard, an assignment should only be available if the start date <= today's date. The student should only see the first assignment in the list. I need to compose tests to cover the following: create a few new assignments with different start dates and assign them to the currently logged in student use the same query that is used for the student dashboard to make sure that the only assignments returned are the ones with a start date <= today's date make sure that the only assignment the student sees on the dashboard is the one with the earliest start date Below I have posted the assignment code from models.py, as well as views.py code that shows what displays on the student dashboard. Please let me know if additional code is needed to help me get started with this. I would like to only use the built in django.test features to write my tests for now, if possible. Thanks very much for any help you can offer! models.py … -

How to add values for checked rows using javascript
I've uploaded a similar question in a previous post, but I'm re-posting because what I'm trying to achieve is a little clearer. We are outputting the list of students as a table. If we check the checkbox and click the Add Teacher button, we want the name of the currently logged in teacher to be added to the teacher field of the selected row. You can get the name of the currently logged in account with {{request.user.name}} .

Optimal way of calling model method while iterating a large queryset in Django
I have an example model as follows: class MyModel(models.Model): #model fields def my_model_method_1(self, *args): #logic for the method. This involves reverse lookup, fk fetching and calculations def my_model_method_2(self, *args): #logic for the method. This involves reverse lookup, fk fetching and calculations Now I am generating an excel file that has the data of the above model. I am querying the model using filter and values. my_model_filter = MyModel.objects.filter(fk_field_1__in=list_of_fk_1_field_ids) my_model_data = my_model_filter.values(all_fields_here) my_args = {"start_date": some_start_date, "end_date": some_end_date} for my_model in my_model_data: model_id = my_model["id"] my_model_object = my_model_filter.get(id=my_model_id) val_1 = my_model_object.my_model_method_1(**my_args) val_2 = my_model_object.my_model_method_2(**my_args) # other logic # the above methods are called again for other calculations. Then the whole data is then converted to excel file. The problem is that calling and getting these methods is taking time. Infact for about 10k instances it is taking about 30 mins to generate the report. I have identified that more time is taking when these methods are called. So is there anyway where i can speed up calling these methods? One way that I reduced the time for my_model in my_model_data: model_id = my_model["id"] my_model_object = my_model_filter.get(id=my_model_id) val_1 = my_model_object.my_model_method_1(**my_args) val_2 = my_model_object.my_model_method_2(**my_args) my_model["val_1"] = val_1 my_model["val_2"] = val_2 for my_model in … -
How to set Debug=False and Allowed_hosts in Django without Http error 500
I would like to publish my website made in Django with Debug=False setting. However, this gives me error 500. I did my best but it still doesn't work.
