Handling Exceptions in Python Django Crispy Forms

Django admin list_display of different data types with null
I know I explained the title poorly, look I have a simple chat app where users can send text/audio/video/image and for me to render those messages I have a method that checks the type of the message and renders it accordingly if it was text then i will set safe to False in my template, else I will display what the function will give me which is an HTML code What I really want is: Admin panel giving me message text[:50] if it was text, if it was audio then i can have an audio preview for it, if it was image or video or file then it will give me the url.

Write BaseSerializer to prevent Stored XSS in Djano
How can we prevent stored xss in Django API's, basically every Text/Char Field should be cleaned. Can we write a Base Serializer using DRF to prevent the attack. Does Django really need to use XSS safe mechanism or it does not effect anything as Django uses ORM for queries? We can use validate_<field_name> method in serializer but that is not a generic solution. Other than bleach can we have a built-in solution -
Can I dynamically place items in two-column template in Django?
The title might not be so clear, so let me elaborate more. I have a two-column template, and want to load some number of items in them. It would look like this: {{item1}} | {{item2}} {{item3}} | {{item4}} {{item5}} | {{item6}} {{item7}} | {{item8}} ... And this is the farthest I've got in my template : {% for a in answers %} <div class="row justify-content-center"> <div class="col-6 text-center"> <div class="row justify-content-center"> <div class="col"> <div class="answers">{{a.title}}</div> </div> </div> </div> <div class="col-6 text-center"> <div class="row justify-content-center"> <div class="col"> <div class="answers">{{a.title}}</div> </div> </div> </div> </div> {% endfor %} Apparently, it doesn't load item as I want to. How do I make this possible? Any help is very much appreciated! :) +Some other codes for further info: views.py def qandaSquare(request, pk): answers = Answer.objects.filter(authuser=request.user.id, question_number=pk) context = { 'answers' : answers, } return render(request, 'main/square.html', context) -
Overriding Django model's id
I have a user model and multiple user types that are related to the user model with a one to one relationship, a goer and a host. Whenever someone creates a goer or a host, an underlying user model is created and saved in the postgresql table. Currently, the goers' and the hosts' id are auto incrementing to the number of goers and hosts. Is there anyway I can override the goers' and hosts' id such that it matches the id of the underlying user that is created? -
Django: Dynamic Annotation and Filtering
I think this should not be complicated but i can't get it right. How can i conditionally count the number of brands in a specific category within a queryset? views.py def get_brands(request): all_brands = brand.objects.values('brand_name','brand_category').\ annotate(brand_proportion=Count('brand_name')/Count('brand_name', filter=Q(brand_category="brand_category"))#I'm stuck here return JsonResponse(list(all_brands), safe=False) I am not sure to filter the brand category and count the number of brands in that category. For example: brand_category 'A' might have: Brand 1,Brand 1 ,Brand 1,Brand 2,Brand 2 Here, the proportion of Brand 1 in category A would be 3/5 = 0.6 or 60% I can calculate the 3 using Count('brand_name') within the queryset, but how can i calculate the 5? brand_category 'B' might have: Brand 1,Brand 2,Brand 3,Brand 4,Brand 5 Here, the proportion of Brand 1 in category B would be 1/5 = 0.2 or 20% Please help.Thanks. -

Query for Intermediate table in Django
Hello how are you? I want to ask you a query on intermediate tables, with a problem that I cannot solve and that I thought was not that difficult. I have a "many to many" relationship between two tables (Sample, Test) using the classes: class Sample (models.Model): tests = ChainedManyToManyField ( 'Test', horizontal = True, chained_field = 'matrix', chained_model_field = 'matrix', through = 'SampleTests' ) class Test (models.Model): test = models.CharField (max_length = 255, blank = True, null = True) class SampleTests (models.Model): test = models.ForeignKey ('Test', models.DO_NOTHING) sample = models.ForeignKey ('Sample', models.DO_NOTHING) class Meta: verbose_name = "Result" verbose_name_plural = "Results" In the Class SampleTests, I put the "verbose_name_plural =" Results "" because I plan to put one more field to put the result of each test in it. As I want to work everything in the Django admin, I configured the admin.py adding: admin.site.register (SampleTest), so in this way I can enter from the menu to this area of "Results" (SampleTest class). But when I click, it throws me this error: "django.core.management.base.SystemCheckError: SystemCheckError: System check identified some issues: ERRORS: <class 'applications.lab.admin.SampleAdmin'>: (admin.E013) The value of 'fields' cannot include the ManyToManyField 'tests', because that field manually specifies a relationship model. … -

Specify __str__() Representation in Django Admin list_display

Django: Uploading a CSV file to AWS S3
We have a Django application that needs to create a csv file on user demand and upload it to AWS S3. We have a function that creates an HttpResponse object response with content_type="text/csv" We have tried a number of things: boto3: s3 = boto3.client("s3") s3.put_object(Body=response.content, Bucket="my-bucket", Key="file_path_and_name.csv") This worked in my local machine, but when deployed to Google App Environment, we got an error that said boto3 could not find credentials. The AWS credentials are in our app settings file. (How would it work on my local machine if we didn't?) django-storages: We have successfully used storages to allow users to download files from this same s3 bucket, within the same app (both locally and deployed). So I thought I would give it a try: storage = S3Boto3Storage() storage.save("file_path_and_name.csv", response.content) This produced the error: AttributeError: 'bytes' object has no attribute 'seek' This is because the save method in S3Boto3Storage calls content.seek(0, os.SEEK_SET) So... Does that mean S3Boto3Storage cannot take a bytestring input file, like boto3 does? (I thought the S3Boto3Storage backend was built right on top of boto3?) I tried io.StringIO(response.content.decode("utf-8")) but I got another error that said the string needed to be encoded before it was hashed. At that … -

Ajax Call <script > $(document).on('click', '#click-btn-post-comment-{{ post.id }}', function(event) { var csrf_token = "{{ csrf_token() }}"; event.preventDefault(); $.ajax({ url: "{{ url_for('create.createcommentquick', postid=post.id) }}", type: "POST", contentType: 'application/json;charset=UTF-8', data: $('subpostcommentform-{{ post.id }}').serialize() , headers: { "X-CSRFToken": csrf_token, }, success: function(data) { if (data.result == 'success') { $('div#success_post_' + data.thepostid).append(data.commentbody); return data; } else { console.log(data) } }, error: function() { }, }); event.preventDefault(); }); </script> My Form - Please note its in a loop! {% if subpostcommentform %} {% include 'common/js/post/quick_post.html' %} <div class="col-12 p-0 m-0 border-top border-dark pt-1"> <form class="p-0 m-0" method="POST" id="selectDevice" action="{{ url_for('create.createcommentquick',postid=post.id) }}" id="subpostcommentform-{{ post.id }}"> {{ subpostcommentform.csrf_token }} <div class="form-group row w-100 p-0 m-0 "> <div class="col-1 p-0 m-0"> {% if current_user.profileimage %} {% if current_user.profileimage == '' %} <img src="{{ url_for('static', filename='images/noprofile.png') }}" style="width:30px;height: 30px" > {% else %} <a href="{{ url_for('profile.main', user_name=current_user.user_name) }}"> <img alt="{{ url_for('static', filename='images/noprofile.png') }}" class="img-responsive" src="{{ url_for('common.profile_image', filename=current_user.profileimage) }}" style="width:30px;height: 30px"> </a> {% endif %} {% endif %} </div> <div class="col-9 … -
Why do I get an IntegrityError when calling Django's create_user helper function?
The current Django doc on Creating users says that the following helper function can be used to create a user: >>> from django.contrib.auth.models import User >>> user = User.objects.create_user('john', 'lennon@thebeatles.com', 'johnpassword') But when I run this code in the Python shell I get this error: django.db.utils.IntegrityError: null value in column "last_login" violates no-null constraint DETAIL: Failing row contains (7, <hashed password>, null, f, john, ... Is the documentation incorrect? I understand that the User object contains a required last_login field but the documentation seems to imply that this helper function will take care of populating it.
