Django - how to fix - request.POST.get returns None?
I'm learning django and trying to get the user's vote from a detailview. The user chooses from radio buttons and clicks on a submit button. The detailview's template's form's action is set to a formview url. Inside the urls I have require_POST on the formview. Inside the template and a for loop: <input type="radio" name="choice" value="{{one.name}}"> <label for="{{one.name}}">{{one.name}}</label><br> Inside a form view: def form_valid(self, form): request = HttpRequest() vote = request.POST.get('choice') return HttpResponse(vote) When I submit the form I can see the choice param in firefox network under post method but the view returns None. What am I doing wrong? -
pinax notifications urls - NoReverseMatch
I am attempting to implement pinax-notifications. The actual implementation is fine and I have created my notifications.

Model not user specific
I have a model called Post. The data in Post is displayed to every user while I want this to be user specific. I'm new to Django. This app is created following the Django for Girls tutorial.

Django - Check if form submit button was clicked?
How can I specifically check if the submit button of my form was clicked? The if form.is_valid() validation does that check but also returns True without clicking the button (When the clean() method was executed). How can I set a variable to True when the submit button was clicked. I try to confirm a upload and when the user clicks the submit button it should execute a Database Query.

Trying to create nested view of django model classes using relations
I am trying to follow this documentation to create nested serializer and api view. https://www.django-rest-framework.org/api-guide/relations/#nested-relationships However, I am not able to understand what did I miss as my results are not expected. I have followed this example to my case and checked various other guides regarding same. Tried different views and different serializer formats. Code for model is this:- class Seats(models.Model): stack = models.IntegerField(null=False, default=0) player = models.ForeignKey(Participant, on_delete=models.CASCADE) state = models.IntegerField(choices=STATE) class Round(models.Model): player_num = models.IntegerField(null=False, default=1) code for Serializers is this:- class SeatsSerializer(serializers.ModelSerializer): class Meta: model = Seats fields = ('stack','state') class RoundSerializer(serializers.ModelSerializer): seats = SeatsSerializer(many = True, read_only=True) class Meta: model = Round fields = ('player_num','seats') I want output like this: { 'player_num': 3, 'seats': [ {'stack': 100, 'state': 'participating', 'name': 'p1', 'uuid': 'ftwdqkystzsqwjrzvludgi'}, {'stack': 100, 'state': 'participating', 'name': 'p2', 'uuid': 'bbiuvgalrglojvmgggydyt'}, ] } However, output I get is: { 'player_num': 3, } -
Django unable to delete/clear data on form
i have a edit_profile view at my django application that also checks if the pgp key the users saves to his profile is in RSA format, Anyways if i add a profile avatar for the very first time it works like a charm, if i want to clear or delete it, im always jumping onto the execpt block and the user avatar remains unchanged.

How to fix code when changing from django 1.0 to 2.0
I need help in changing the url.py code in django 1.0 to django 2.0 I am a beginner in Django and I am following the book called "The Definitive Guide to Django".

Relational database in django in a popup form
I have two tables in a django database which are as follows: Manufacturer and Transporter Both of these tables are filled by their respective forms.

Boto3 generating different links locally and on elastic beanstalk with a django application
I am a bit confused right now: I have a Django Application that uploads files to s3 and generates download links in the admin panel, to retrieve the files after uploading. I use boto3 for signing upload and download links. It all works fine locally but as soon as I deploy it to elastic beanstalk the links to download are not working anymore and it seems it generates the links with an old singing version. The upload still works though. I am generating the links like so: def downloadUrl(self): s3Client = boto3.client('s3') bucketName = getattr(settings, "AWS_STORAGE_BUCKET_NAME", None) fileurl = s3Client.generate_presigned_url('get_object', Params={'Bucket': bucketName, 'Key': self.url.split(bucketName + '/')[1]}, ExpiresIn=100) return format_html("<a href='{url}'>{url}</a>", url=fileurl) And the funny thing is it works locally and the generated links are different: Local Link: https://bucketname.s3.amazonaws.com/uploads/something/zips/2019/03/28/App%20Beschreibung.pdf.zip?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAJNND443OXASGOY2Q%2F201330328%2Feu-central-1%2Fs3%2Faws4_request&X-Amz-Date=20190328T101414Z&X-Amz-Expires=100&X-Amz-SignedHeaders=host&X-Amz-Signature=4fe4d31dc1fd1f772217656654025b669513597c3f91f857fb722ff63a6c0194 Link Generated by Elastic Beanstalk Deployment: https://bucketname.s3.amazonaws.com/uploads/something/zips/2019/03/28/App%20Beschreibung.pdf.zip?AWSAccessKeyId=ASIA2K3XQKDHVDBX3GWN&Signature=w%2FWRh6tf%2Ba7k91Odop3ly9gEJDw%3D&x-amz-security-token=AgoJb3JpZ2luX2VjEHIaDGV1LWNlbnRyYWwtMSJIMEYCIQD7hU0fX24bksIM3vlQxZjYeje2sDm%2FQeeFQqUt7MwDpQIhAIozM1i1%2FmGK2Xo0RXmR7UWAB2FRPdkQy3aBOisS3BzuKuADCCsQABoMNzEwNTMwODQ2OTI3IgxfJIvFGgD5WL6TwccqvQO1Bsri%2FTmpvaARkFA%2BOnhLRUv9FFfdFf6H8W4IY38OI6CWzvct%2BgmE14D06GHaCh65wKH%2BhR9ZT3V18sW9U4RM%2FpS64hESmC8SUerzpPv9RmuXgA8hQl%2BwRJaTFLGFRFrHdHFoeJAeLIKjK2B7lDjLzNALtvegnLrBYoBtT0Ga2a7CC7avWMevvQ0jAjuSMiEOS4FjXNwHInkb%2FCrX3EXk2Me9OaufICHGH0ZTN2WNAGtOPsY15YJyLf0WgDl7SxVLuAnA4nUzeMglsdaL9ZbUlsdleJtHTQefNqCXXsm4FIup%2Fe%2FNFkn9g7XDH9%2F9IXW%2FNZyBAtfrRoPmDwvv0KpeYPpRpkVKBa5TxQU1c6ei3AiHnIQZRdO5oEqW47qv9hM8%2Fw9U9VlDqyUy5BKbGnv7GTLCdh4%2FwcYEnlfgr8QdK%2BJzyQYdgpMYqw3hj%2FTDW8mJVI9AD3RpHnD0XwIL3BBH5fUgcNZm2vGLG5nOcav7u2YaeqdFiY95SkdL5C8CLv%2BRLYABXyAbeWPUtFzgTtdUFFlv5epAQO2cPOD%2BM3V%2BjhfTQa4WUSIRCwUpSQg3dahIvV75cbKdsdZ7bL1tRMIqz8uQFOrMBC7isGac1kJ0TqHMbiQ77QauekC9c1gy6wgnKu9enc2x4VvyhClhvTvmEFm5NW3CmU5LIXf9V4Df9ML7Mf3Nf2uhuAhQdTKoAIGPiVWz%2FB3Lh%2F58%2FLbRbIRNgWk6IDg88dzgevitkXSC0OokmpB3qbBj%2BGXjIHttHqdBKnjG22aud3wrMk6YxH8b0CfelmcN5vHykpMYgdfgNHvFKrea417ozh5CLfZ9PYQoug0iqsm9nqoU%3D&Expires=1553768535 as you can see the signing is different but I do not understand why.

Logical constraint in Django - need logics
Now this problem I am facing currently is having constraints. Let me explain what sort of constraints I am talking about, I am working on a survey application that is built on Django 2x, The survey that my project creates are simple questions, but I want to add constraints in a sense that when a question A is asked with options a, b. If the answer for question A is a then I should get question B or if the answer is b then I should get question C. Now the problem is I cannot have if-else-elif conditioning written there for this purpose as the data (questions and options) are coming dynamically, like on runtime!
