Confusion regarding Django and SECRET_KEY
Recently finished my app and I am ready to deploy it but I don't understand how to set the application's SECRET_KEY. I'm trying to change my database from sqlite to postgresql, but I get the following error: raise KeyError(key) from None KeyError: 'SECRET_KEY' development.py from nurs_course.settings.common import * ALLOWED_HOSTS = ['0.0.0.0', 'localhost'] SECRET_KEY = '9t*re^fdqd%-o_&zsu25(!@kcbk*k=6vebh(d*9r)+j8w%7ci1' DEBUG = True production.py from nurs_course.settings.common import * DEBUG = False SECRET_KEY = os.environ['SECRET_KEY'] # SECURITY WARNING: update this when you have the production host ALLOWED_HOSTS = ['0.0.0.0', 'localhost'] common.py has all the other settings required.

How can I convert this SQL query to Postgresql in Django?
I have this query that I want to write in Postgres in Django. I can phrase the query using SQL command as DELETE FROM NOTIFICATION_MESSAGES.JSONFIELD["notifications"] WHERE POST_ID=POST_ID AND ACTIVITY="LIKE"; My jsonfield looks something like this: user_id : { notifications : { post_id: post_id, activity:[like, comment...] } } } Please let me know if you need any more information. Thanks in advance! EDIT: Till Now I have tried this: notification_messages = NotificationMessages.objects.get(user__id=user) notification_messages.doc["notifications"].pop(post_id) notification_messages.doc["notifications"].pop("activity") -

Django - save under determined condition
I want a FeedstockFormula model (it has a ratio and a name field) to save if and only if the ratio value is something different than 0 or null or blank.

Django update InMemoryUploadedFile with Piexif
I am trying to strip out exif data on an uploaded image before continuing to do some other processing to it before saving to the server. I am using piexif as in this answer to strip out the exif metadata. However, piexif.insert() documentation requires the path to the image being modified. Can piexif be used to write to a file in memory? An InMemoryUploadedFile has a name attribute which seems to provide the path to the file, however it is not working as expected. def modifyAndSaveImage(): # Get the uploaded image as an InMemoryUploadedFile i = form.cleaned_data['image'] # Use piexif to generate an empty exif byte dump exif_bytes = piexif.dump({}) piexif.insert(exif_bytes, i._name) # What should the second parameter be? # continue using i... -

How to get html from page in Django

Cannot Filter ChoiceField in Django with Multiple Keys and One Value
I am trying to filter a choicefield in Django by attempting to display one value with multiple keys. I understand choicefields are normally one key per value, but I have some values (names) which are the same with different id's in my database. I do not want to display the names more than once in the choicefield, so I wrote code to display items of a dictionary as a tuple with several id's and one value. I would like to filter these objects (animals) by "species" and "gender," so I created two modelchoicefields in my form. I am able to filter singular names by "species" and "gender" but not the duplicate names. The only error messages I get are Not Found: /filter_species/(1, 4)/ and "GET /filter_gender/(1,%204)/ HTTP/1.1" 404 4306. The "1" and "4" are respectively id's 1 and 4 for two animals with the same name. I have included my code from my forms, views, URLs, and animals template. Any help would be much appreciated as I am fairly new to Django and am still learning. Note: I am wondering if my URLs may be an issue with not showing regex for the parenthesis (tuple)? If so, I've been researching … -

Django collectsatic keeps collecting old files
When I run my localserver I noticed that Django is loading a background image I changed a while ago. I checked the folder where my static files are and my new background image was there. Both images had the same name. I changed the name and did collectstatic again and in my STATIC_ROOT the old image appeared. Later I tried python manage.py collectstatic --clear, I also cleared my cache, restarted my server. I tried deleting the file and changing the name and the path and Django keeps collecting old static.

How to solve problem with Django & Mongo on azure appservice
I managed to develop django app with vs code but I couldnt publish it. I think I couldnt set up virtual env properly. But then I made it with normal visual studio and that created me virtual environment which azure accepted well. It was working well but with sqlite. I needed mongoDB. I found instructions for dns and djongo and settings.py, so on terminal: 'python manage.py runserver' (locally, but with atlas mongo) it works well. But now, azure isn´t accepting my app. It says only SQL this and that XXXX are accepted... Could someone help me? Heres all the code: https://github.com/Point-SimoSiren/django-suppliers It is now again with sqlite but setting.py: DATABASES mongo stuff I used are on comments right below that.

Django HttpResponse returning object instead of stated string
I am using Django and React. I need to send a string from Django to React. I have tried using both HttpResponse and JsonResponse but both seem to be returning a response object that does not include the data.

I've looked on StackOverflow and around the web and haven't found a solution. I am also not sure whether this is a problem with Django or React but it seems like a Django problem.

Django DRF (De-)Serializer not working for me?
I'm stumled upon a case I don't understand. I have two related models: class Course(models.Model): code = models.CharField(max_length=10, default='') semester = models.CharField(max_length=10, default='') class Meta: unique_together = [['code', 'semester']] and: class StudentWork(models.Model): code = models.CharField(max_length=10, default='') course = models.ForeignKey(Course,on_delete=models.CASCADE, related_name='student_works') deadline = models.DateTimeField(blank=True) In the StudentWorkSerializer I'd like to expand a course field into [code, semester]: class CourseNaturalSerializer(serializers.ModelSerializer): class Meta: model = Course fields = ['code', 'semester'] class StudentWorkWithCourseSerializer(serializers.ModelSerializer): course = CourseNaturalSerializer(read_only=True) class Meta: model = StudentWork fields = ['code', 'course', 'deadline'] This works nicely for GET, e.g. I receive this: {'code': 'HW1', 'course': {'code': 'T101', 'semester': 'S20'}, 'deadline': '2020-09-04T23:59:00+03:00'} but this does not work for POST: POST /studentworks json=dict(code='HW2', course={"code": "T101", "semester": "S20"}, deadline="2020-09-04T23:59") says in the stacktrace: django.db.utils.IntegrityError: NOT NULL constraint failed: botdb_studentwork.course_id So this looks to me that {"code": "T101", "semester": "S20"} does not de-serialize into Course object and it's id is not passed to StudentWork's create? What should I do? Thanks in advance! -
Django form not submitting in POST
Been having an issue where I am unable to upload files into my form. From what I can gather on my own, it's because I'm not submitting in POST (since uploaded files aren't saved unless you're in POST) but I don't know why that's the case.

Django Extended Group's Permissions not applied to users
So I have extended Django's Group model to add an extra field like so: class MyModel(Group): extra_field = models.TextField(null=True, blank=True) On doing this, each instance of MyModel created, creates a Group instance as well. If I add a user to the resulting group with user.groups.add(group), the group is added as expected. However, the permissions from the MyModel group do not seem to have trickled down to the user i.e Doing user.get_all_permissions(), get_group_permissions() or even testing a user.has_permission(mygroup_permission) returns nothing. Only permissions from pure Group instances(created before extending the model) are shown. Is there anything I need to do for permissions on customised groups to be visible on the users? TIA -
