I created a new IAM user following this tutorial https://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html and attach this politics: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "ses:*" ], "Resource": "*" } ] } I´m using this lib https://pypi.org/project/django-ses/, but got this erro message "An error occurred (SignatureDoesNotMatch) when calling the GetSendQuota operation: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details." Someone can help to send an email? -

Save Django forms from 2 different models into third model
I new-ish to Django and need some help with Django Forms. I'm building a poll like app to learn, but I would like to have the poll questions come from one model, while the answer choices from other model. However I have issues getting that data back to the CBV using forms. class RiderModel(models.Model): full_name = models.CharField(max_length=500) number = models.IntegerField() def __str__(self): return self.full_name class QuestionModel(models.Model): category = models.ForeignKey(CategoryModel, on_delete=models.CASCADE, default=1) question_text = models.TextField() def __str__(self): return self.question_text class UserVoteModel(models.Model): user = models.OneToOneField(get_user_model(), on_delete=models.CASCADE) event = models.ForeignKey(GameModel, on_delete=models.CASCADE) question = models.ForeignKey(QuestionModel, on_delete=models.CASCADE) answer = models.ForeignKey(RiderModel, on_delete=models.CASCADE) In the CBV I have this function to get the data to template, but not sure how to get this data back into the UserVoteModel def get_queryset(self): event = self.kwargs['short_name'] category = GameModel.objects.filter(short_name__iexact=event)[0].question_category return {'questions': QuestionModel.objects.filter(category=category), 'riders': RiderModel.objects.all()} Thank you in advance for your help. -
{"message":["This field is required."],"status_code":400} error when posting requests in python to a Django rest framework
Hi I have a code to post json data to a url but I am getting {"message":["This field is required."],"status_code":400} this as response. Even though i have no message fields in my code or data. import requests import json from urllib3.exceptions import InsecureRequestWarning refreshurl = "/api/login" refreshheader = { "accept": "application/json", "content-type": "application/json", } refreshfields = { "username": " ", "password": " " } #api call for refresh token access_token_response = requests.post(refreshurl, headers=refreshheader, json=refreshfields, verify=False) myaccesstoken = access_token_response.json()["access"] #api call for accesstoken url2 = "https://google.com/upload_data" #dummy url header2 = { "accept": "application/json", "content-type": "application/json", "Authorization": "Bearer {}".format(myaccesstoken)", } fields = { { "name":"alia","id":"GSHBA678","status":"active","zipcode":56839}, } #api call to upload data requests.packages.urllib3.disable.warnings(category=InsecureRequestWarning) response = requests.post(url2, headers=header2, json=fields, verify=False) print(response.text) print(response.status_code) Instead of Bearer if i put token in JWT it is giving me {"message":["Authentication credentials were not provided"],"status_code":401}.

How can I optimize the function given below so that number of hits to the database are reduced?
I have this function def get_lesson_posts(self): learning_units = self.get_learning_units() comments = [] for unit in learning_units: if unit.lesson is not None: lesson_ct = ContentType.objects.get_for_model(unit.lesson) title = unit.lesson.name try: post = Post.objects.get( target_ct=lesson_ct, target_id=unit.lesson.id, active=True, title=title ) except Post.DoesNotExist: post = None if post is not None: comments.append(post) return comments There is a for loop iterating on each unit and creating a content type object (lesson_ct) which is then used to get a post from the Post table. Now I think on each iteration a database query is executed by the Post model to get a post object. The problem is I am not able to think of a better method to get the Post object without making queries on each iteration. I need help in writing the function properly so that I can reduce the number of queries being executed. For reference I am posting the Post model and Lesson Model below. class Post(ForumBase): title = models.CharField(max_length=200) target_ct = models.ForeignKey(ContentType, blank=True, null=True, related_name='target_obj', on_delete=models.CASCADE) target_id = models.PositiveIntegerField(null=True, blank=True, db_index=True) target = GenericForeignKey('target_ct', 'target_id') class Lesson(models.Model): # Lesson name name = models.CharField(max_length=255) # Markdown text of lesson content description = models.TextField() Please tell me if more information is required.

Including Modified Django Package in Project
I am trying to figure out how to include a modified package into a Django 2.2 project. The package has been modified. A few skins have been added to the editor. That is, it is no longer the same package that is installed when one does pip install <package>. My understanding is that it now needs to be added to source control and probably added to the project directory, instead of being located within a virtual environment's directory. The question is what is the way go about this situation most efficiently. Should I add the package to the project's directory or is there a way to somehow manage this through pip and requirements.txt? -

Django - Sitemap - Manually set absolute urls
I'm generating a sitemap but the website that this sitemap is for has a different URL routing and a different domain. I thought that overriding location method will work but the problem is that Django automatically adds Site url before each url. http://example.comhttps://thewebsite.com... <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url><loc>http://example.comhttps://thewebsite.com/article/123/slug</loc><lastmod>2021-05-10</lastmod> <changefreq>hourly</changefreq><priority>0.5</priority> </url> </urlset> class WebsiteSitemap(Sitemap): changefreq = "hourly" priority = 0.5 def items(self) -> typing.List: items = [] items.extend(Article.objects.home()) return items def location(self, obj: typing.Union[Article]): return obj.website_full_url def lastmod(self, obj: typing.Union[Article]) -> datetime: return obj.modified Is there a way to tell Django not to build the URL automatically? -

Django FastApi 2 servers
Please help me. I have a project on Django, in which some of the processes go through celery. But now I want to transfer all the complex data processing to another server. I plan to use FastApi. But the question arose - how to properly organize the work with the client files that will be processed . Do I need to receive files from the client and save them on the second server, or do I need to save them on the first server and send them over tcp? Perhaps there are other options ? How do I do this ? -

Django ORM more than one row returned by a subquery used as an expression

DRF spectacular swagger ui problem when extending a new TokenAuthentication for DRF
when extending a new Token Authentication class from rest_framework_simplejwt.authentication.JWTAuthentication drf-spectacular swagger-ui authorize button disappears and there is no way to add token bearer, I guess when you subclass it goes wrong. steps to reproduce: first, create a Django project with rest framework and drf-spectacular and simple jwt installed and configured with documentation guidance. got to /swagger-ui/ and it works fine. then create a subclass of JWTAuthentication like below: from rest_framework_simplejwt.authentication import JWTAuthentication as JWTA class JWTAuthentication(JWTA): pass and in your settings: REST_FRAMEWORK = { 'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema', 'DEFAULT_AUTHENTICATION_CLASSES': ( 'path_to_your_module.JWTAuthentication', ), } and now if you go to /swagger-ui/ there is no authorize button!!! how can I fix this? and I even tried to create an AuthenticationExtension like: from drf_spectacular.contrib.rest_framework_simplejwt import SimpleJWTScheme class SimpleJWTTokenUserScheme(SimpleJWTScheme): target_class = 'spec.test.JWTAuthentication' but there is no way to register it anywhere nor on the internet nor in the documentation!! how can I fix authorize button when overriding an Authentication class?? -
