Django: Remove packages that are no longer needed from requirements.txt
I just finished my first Django project and wanted to add a requirements.txt. When I type pip freeze I get all the packages in the venv, even the ones I didn't include in my last git commit. How do I get only the packages I used for my last commit? -
How can I unit test Sentry's before_send callback?
I want to write a strip_sensitive_data function and pass it into Sentry's before_send callback, as in the example from their own docs https://docs.sentry.io/error-reporting/configuration/filtering/?platform=python import sentry_sdk def strip_sensitive_data(event, hint): # modify event here return event sentry_sdk.init( before_send=strip_sensitive_data ) I'm working on a Django app and want to find a way to patch or mock this callback using Django TestCase. Is there a simple way to do this? -

Why do I get "The 'img' attribute has no file associated with it." error in Django?
So I have this simple Django application where users can post diary as well as images. Here, uploading image is optional, so I have left the field as not required. The problem is when I leave the ImageField empty. Saving the post w/o image works fine, but when I try to GET the post, I run into the error. First let me show you the code. models.py class Diary(models.Model): objects = models.Manager() # some other stuff here img = models.ImageField(null=True, blank=True, upload_to="everyday_img") forms.py class DiaryInputForm(forms.ModelForm): # some other stuff here. img = forms.ImageField(required=False) views.py def InputDiary(request): form = DiaryInputForm(initial={'authuser':request.user}) if request.method == 'POST': form = DiaryInputForm(request.POST) if form.is_valid(): instance = form.save(commit=False) instance.authuser = request.user # some other stuff here user_img = request.FILES.get('img', None) instance.save() return redirect('/diary/diarymain') return render(request,'diary/diaryinput.html', {'form':form}) def ViewDiary(request, authuser_id, slug): today = Diary.objects.get(slug=slug) return render(request, 'diary/diaryview.html', {'today' : today}) diaryview.html ... <div class="row justify-content-center"> <div class="col col-12"> <div class="detail-contents"> <img src="{{today.img.url}}" class="user-img"><br> {{today.what|safe}} </div> </div> </div> ... So when diaryview.html is loaded, the error occurs. I know it's obviously because the img column has no data, but I have no idea on how I should deal with it. Thank you very much in advance. :) -

How can I directly put a model data into another form's input in Django?
I made a register page and a checkout page(named thankyou in my code) and then i integrated a payment gateway API with my checkout page's form.

Django, prefetch related raises key error

Django Image File handling
Suppose I have a model Person, something like that: class Person(models.Model): first_name = Models.CharField(....) last_name = Models.CharField(....) Now, I want to add a user profile image. I have thought about adding the ImageField directly or 'wrapping' it in my own custom model and adding a FK to the Person model, with the wrapper looking like that: class MyImageField(models.Model): image = models.ImageField() uploaded_at = models.DateTimeField(...) description = models.CharText(...) owner = models.ForeignKey(Person) #... other fields for meta data as needed class Person(models.Model): ... profile_picture = models.ForeignKey(MyImageField) Would this approach be beneficial? I think, using a custom model has a few benefits: More flexibility in terms of storing associated meta data Expandable Could be kept generic for all usecases where images are needed (User profile, gallery, etc.) Single point for encoding filenames, as creating a hash as filename seems better than storing the file under the original name for avoiding duplicate names (as django normally does, as I understand it) Possibility of adding an owner property, to allow for easier access control (Check if accessing user is owner, or in the same group or whatever) Regarding the last part, since images (and files) are stored on the servers file system and not in … -
Bootstrap selectors not making much sense
I'm brand new to using Bootstrap and I'm having a tough time understanding the basic logic of it. I understand the idea behind some of it, but other things completely perplex me and I can't find too many resources that explain it without referring to other concepts I'm totally unaware of. I'm wondering if someone can give me a hand with working through what different selectors are for. Here's some example code copied straight from Python Crash Course (from a project where Django is used to build a web app and Bootstrap 4 is used to style it): <body> <nav class="navbar navbar-expand-md navbar-light bg-light mb-4 border"> <a class="navbar-brand" href="{% url 'learning_logs:index' %}"> Learning Log</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span></button> <div class ="collapse navbar-collapse" id="navbarCollapse"> <ul class="navbar-nav mr-auto"> <li class="nav-item"> <a class="nav-link" href="{% url 'learning_logs:topics' %}"> Topics</a></li> </ul> What I (think) I know: From what I've been able to understand from the documentation & experimenting, assigning a class to an HTML element pulls premade style rules from somewhere in the background and applies them to my project, so <nav class="navbar navbar-expand-md navbar-light bg-light mb-4 border"> would tell Bootstrap that this is a navbar (from navbar), … -

Django Rest Framework: Accessing validated_data outside of def create() method
so I know my question is horribly written but I'm not sure the best way to phrase this. Let me explain. I'm trying to get my serializer class to process multiple value types for a specific field. For example, I need to Post the JSON values of items called "Temp (C)", "Humidity(%)", etc all under a specific field called "value" in my serializer class. I also of course have a model in models.py called "value".

Django-guardian get all obects user can view including anonymousUser?
I'm starting to play around with django guardian and I'm trying to understand how folks use this to display both restricted and unrestricted objects to a user. Based on my understanding of the docs, anything that should be "world viewable" should have the view_model attribute assigned to the AnonymousUser account for each object. This makes sense, but I am curious how to efficiently display objects to an authenticated user where the user has view permissions and AnonymousUser has view permission. If there is no user currently authenticated the objects assigned to AnonymousUser are all displayed, but what is the best way to display all objects to an authenticated user, which include objects only that user can view and anything assigned to the AnonymousUser? Right now this is my solution: def myView(request, template_name = "app/template.html"): MyStuff = get_objects_for_user(request.user, 'app.view_mymodel') AnonymousUser = User.objects.get(username='AnonymousUser') AnonStuff = get_objects_for_user(AnonymousUser, 'app.view_mymodel') MyStuff = MyStuff.union(AnonStuff) return render(request, template_name, {'MyStuff': MyStuff}) Is there a more straight forward way to return all objects a user can view and the anonymous user can view? Or is there a different way to make an object viewable by everyone that doesn't involve the anonymousUser account when using guardian so that it is … -
How to add dynamic meta tags to react app based on Django API
I have a React front-end and a Django (DRF) API. The React front-end has a route like /content/:id where a different page with a different image is rendered depending on the :id. I'd like to change the index.html meta tags based off the content from that request which comes from Django. There are many tutorials on how to do this with express and React: http://www.kapwing.com/blog/how-to-add-dynamic-meta-tags-server-side-with-create-react-app/ but how can I do it with a Django back-end?

class Question(models.Model): ... posted_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) # following fields are for sorting by popularity popular_param = models.BigIntegerField(default=0) class Answer(models.Model): question = models.ForeignKey(Question, related_name='answers', on_delete=models.CASCADE) ... posted_by = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) What I want to achieve: Whenever an Answer is created, popular_param of the Question model should be incremented by 10. I have tried the following, by overriding perform_create in the viewset. class PostAnswerViewSet(viewsets.ModelViewSet): """ this is where you post answers """ queryset = Answer.objects.all() serializer_class = PostAnswerSerializer def perform_create(self, serializer): answer = self.get_object() answer.question.popular_param = F('popular_param') + 10 answer.question.save() serializer.save() OR def perform_create(self, serializer): Answer.question.popular_param = F('popular_param') + 10 Answer.question.save() serializer.save() I seem to be missing some syntax but can't figure out what. None of the other questions on SO have helped so far.
