How to read env vars from settings in django unittest?
I am new to unittesting. I want to read some env vars in django unittests, but I am having some troubles when trying to read the env var from django.conf.settings, but I can read the env var using os.environ.get(). How can I access the current env var from django.conf.settings? The test code looks like the following: from unittest.mock import patch def test_functionality_in_non_production_environments(self): with patch.dict('os.environ', { 'ENVIRONMENT': 'local', 'ENV_VALUE': 'test_env_value', }): from django.conf import settings print(settings.ENV_VALUE) # --> DOES NOT PRINT 'test_env_value' print(os.environ.get('ENV_VALUE')) # --> PRINTS 'test_env_value' I am trying to test the correct behaviour of the code depending on the env var. In some parts of the code there is some logic like: if settings.ENV_VALUE and setting.ENVIRONMENT == 'local': # do some stuff -

Single data from the relation m2m field - Django

Django - Return multiple columns in subquery
I have objects that are made up of multiple other objects - specifically an event, that can have multiple dates, and multiple appointments on those dates. Any changes to any event, date or appointment are logged using Django Auditlog. I need to make a query that shows all events and the first and last edit on the event or any children objects related to it. I can create the query that will go through the auditlogs but I wondered if it was possible to return both the first and last edit timestamp in a single subquery? It looks like it is only possible to return one. Otherwise I suppose I could call the query once (which seems clunky) or to drop into raw sql but that was something that I wanted to avoid. -

How to make search in combinations of fields available in Django Haystack
Suppose I have a Search index like this for a model of a Chapter within a book. class ChapterIndex(indexes.ModelSearchIndex, indexes.Indexable): # Normal document field - most often searched text = indexes.EdgeNgramField(document=True, use_template=True) # Other fields Id like to be searchable title = indexes.EdgeNgramField() author = indexes.EdgeNgramField() Now suppose a user selects a search within title and author fields and enters the following text: "titlepart author_lastname", which is not an unlikely search. I build my searchquerys like this: SQ(title=AutoQuery(query)) | SQ(author=AutoQuery(query)) The problem is, that the full text is now in neither of the fields author (misses the titlepart) and title (misses the authors last name). Therefore a correct chapter (where the author field contains the last name and the titlepart is in the title) is not selected by django-haystack. I am using the whoosh backend for this, but I guess it is independent of that. Here is the different solutions I have tried. Splitting up search terms. Splitting up the terms and searching for everything by itself yields a too generous search behavior. For example, the search for "foo" yields 10 results. Too general, specify more and enter "foo bar". The search still yields 10 results, as the word "foo" … -
Django - Group by two columns to create a stacked column chart with Highcharts
I have a Student model for my Django app, like this: from django.db import models class Student(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) major = models.CharField(max_length=100) year = models.IntegerField() And I'm trying to create a stacked column chart, using Highcharts. So the output is like this: The idea is that I want to show the number of students that we have in each year, stacked with majors. This is all the data for this example, excluding the names: [{'major': 'Computer Science', 'year': 1394}, {'major': 'Electrical Engineering', 'year': 1394}, {'major': 'Computer Science', 'year': 1394}, {'major': 'Chemistry Engineering', 'year': 1395}, {'major': 'Computer Science', 'year': 1396}, {'major': 'Computer Science', 'year': 1394}, {'major': 'English Literature', 'year': 1395}, {'major': 'English Literature', 'year': 1394}, {'major': 'Computer Science', 'year': 1395}, {'major': 'Chemistry Engineering', 'year': 1397}, {'major': 'Art', 'year': 1397}, {'major': 'Electrical Engineering', 'year': 1398}, {'major': 'Electrical Engineering', 'year': 1399}, {'major': 'English Literature', 'year': 1399}, {'major': 'Computer Science', 'year': 1400}, {'major': 'Chemistry Engineering', 'year': 1397}, {'major': 'English Literature', 'year': 1397}, {'major': 'Physics', 'year': 1393}, {'major': 'Physics', 'year': 1393}, {'major': 'Chemistry Engineering', 'year': 1392}, {'major': 'Persian Literature', 'year': 1392}, {'major': 'Computer Science', 'year': 1392}] I grouped the two major and year columns, grouped = (Student.objects .values("major", "year") .annotate(count=Count("id")) .order_by("major", … -

django automatic creation of the form from the model

Trying to create an object in Django's database with React using User as foreign key (rest-framework)

Custom lookup in Django (filter parameter different type than field type)
I have a simple model in Django. class Books(models.Model): title = models.CharField(max_length=255) page_size = models.IntegerField(null=True) An example instance of this model may look like this: ("Alice's Adventures in Wonderland", 70). I would like to create a lookup which would allow users to filter the books by page sizes in the following form if the user types (inside the filter box) >n Django filter would return only books which have more pages than n, if the user types <n Django filter would return only books with less pages than n. To sum up I would need a lookup __cmp which would be capable of joining the queryset before executing it. So I would like to have an if-else block implemented somewhere inside. filter_param, value = filter_param, filter_value = list(user_filter) if filter_param == ">": qr = Books.objects.filter(page_size__gt=n) else: qr = Books.objects.filter(page_size__lt=n) Is it possible to create a custom lookup which would implement such logic? -
