Linking profile model to user
I created a separate profile form from what users enter when they sign up and I am trying to attach information inputted in this form to its relevant user. I have tried creating a foreign key in my profile model that refrences the user model however, I could not get that to work. models.py class Profile(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) bio = models.CharField(max_length=2000) instrument = models.CharField(max_length=255, choices=instrument_list, blank=True) level = models.CharField(max_length=255, choices=level_list, blank=True) preferred_language = models.CharField(max_length=255, choices=language_list, blank=True) time_zone = models.CharField(max_length=255, choices=time_list, blank=True) def create_profile(self, bio, instrument, email, level, preferred_language, time_zone): profile_obj = self.model(bio=bio, instrument=instrument, level=level, preferred_language=preferred_language, time_zone=time_zone) # add arguments full_name=full_name profile_obj.save(using=self._db) return profile_obj views.py def profile_page_edit(request): if request.method == 'POST': form = ProfileForm(request.POST) if form.is_valid(): bio = request.POST.get('bio', '') instrument = request.POST.get('instrument', '') level = request.POST.get('level', '') preferred_language = request.POST.get('preferred_language', '') time_zone = request.POST.get('time_zone', '') #profile = request.user #form.save() profile_obj = Profile(bio = bio, instrument = instrument, level = level, preferred_language = preferred_language, time_zone = time_zone) profile_obj.save() return redirect('/student/profile-page') else: form = ProfileForm() form = ProfileForm() context = {'form': form } return render(request, 'student/profile_page_edit.html', context) def profile_page(request): form = ProfileForm profiles = request.user.profile.objects.all() args = {'form' : form, 'profiles' : profiles} return render(request, 'student/profile_page.html', args) I am trying … -
Zappa Django project "DisallowedHost at /" even though ALLOWED_HOSTS are correct
I am deploying my django app on AWS Lambda and RDS using zappa serverlessly I am using a Postgres database as my RDS instance. When I run my commands I am not getting any errors Your updated Zappa deployment is live!: https://56ks43234234fhkshdfk48.execute-api.us-east-1.amazonaws.com/production However when I click that link I get DisallowedHost at / Invalid HTTP_HOST header: '56ks43234234fhkshdfk48.execute-api.us-east-1.amazonaws.com'. You may need to add '56ks43234234fhkshdfk48.execute-api.us-east-1.amazonaws.com' to ALLOWED_HOSTS.

Is it possible to use/test a value of Django's BooleanField without a model?
I'm trying to make a workflow where the user enters data on one page, then has to check the data and tick a tickbox to accept the T&C's. So the code has to check that the checkbox is checked before going on, but doesn't care until the second step. It's not a bound field and I think that's the problem - I don't need a model just to handle a workflow, and I don't want to have to store, in a database, a simple ephemeral field in a form! I'm running Django 2.1.5. I've tried every possible combination of: test_form.fields['tickbox'].value - doesn't exist, which is ridiculous test_form.fields['tickbox'] == False - value doesn't change at all request.POST['tickbox'] seems to go missing? views.py from django.http import HttpResponse from django.template import loader from django.forms import Form, CharField, BooleanField class test_form(Form): name = CharField() tickbox = BooleanField(required=False, initial=False) def testview(request): if request.method == 'POST': testform = test_form(request.POST) if testform.fields['tickbox'] == True: do_things() else: dont_do_things() else: testform = test_form() template = loader.get_template('testform.html') context = { 'testform : userform, } return HttpResponse(template.render(context, request)) I should be able to test the value of the field and get a changing response depending on if the user has ticked … -

Filter based on foreign key
So i was working on this problem for many days already and can't make it work. Basically I have three models class Year(models.Model): year = models.CharField() class Book(models.Model): name = models.CharField( verbose_name = "Library Name", max_length = 255 ) author = models.ForeignKey( Author, on_delete=models.CASCADE ) year = models.ForeignKey( Year, on_delete=models.CASCADE ) class Author(models.Model): name = models.CharField( verbose_name = "Author's Name", max_length = 255 ) num = models.CharField( max_length = 255, default=0 ) For example, If I pass 2018 i want retrieve all the Authors who published book in 2018. I tried different queries like Year.objects.filter(year=2018).filter() and don't know how to filter the rest -

Rest Framework serializer to create parent and one of multiple child types
I have a serializer that creates a parent model, then creates a child model depending upon some information provided to the parent: class InitializeFormSerializer(serializers.Serializer): title = serializers.CharField() category = serializers.ChoiceField(choices=CATEGORY_TYPES) def create(self, validated_data, user): identifier = validated_data.get('title') obj, created = Parent.objects.update_or_create( user=user, ) if created: item_type = validated_data.get('item_type') if item_type == 'FIRST_TYPE': Child1.objects.create(identifier=obj) elif item_type == 'SECOND_TYPE': Child2.objects.create(identifier=obj) return obj This works, but the item_type check feels clumsy. Is there a paradigm within Django or Rest Framework I'm missing that might make this more elegant? -

How to generate thumbnails in MEDIA_DIR from images stored in STATIC_DIR with Django?
I have a number of images stored in my static dir, set as per my django settings. These images are all different sizes and aspect ratios. They display fine in my django application at the moment. I want to generate thumbnails from these images using "smart crop" functionality (which looks for the parts of the image with the most entropy when reducing instead of just centering). I've tried this both with sorl-thumbnail and the easy_thumbnail packages that have the "smart crop" functionality I am after. In both cases, I get an error: SuspiciousFileOperation at /products The joined path (/static/images/products/test1.jpg) is located outside of the base path component (/home/jake/webapps/my_webapp/my_site/media) I understand that media and static dirs are meant to be distinct from each other, with media being for where users upload files and static being files that are part of the site. But, since thumbnail packages need to read images from my static dir and generate them in my media dir, how can I resolve this security conflict? Surely this should be a common configuration for people generating thumbnails, basin them on images in their static dir? Yet I can't find anything on this error coming up in this context before, … -
multiple field search in dajngo app wrong results

Images database schema
I'm trying to store user profile pictures, uploaded images in statuses, etc. on my site. When the user uploads a profile picture, there should be 3 types of the same image (Original image, medium sized, small sized). This is stored in the filesystem. A user can upload a maximum of 2 pictures in their statuses and each of these images follow the same types (original, medium, and small). The reason why I'm making different thumbnails of the same image is to serve those images depending on which screen display the user is accessing the site. That being said, what is the best way to store these image's file paths in my database? What kind of schema makes the best sense, or if there is another better way I can serve these images, what is the best approach? For the profile image table, I was thinking something like this: id user_id size img 1 2 S /img/s/avatars/ex.jpg 2 2 M /img/m/avatars/ex.jpg 3 2 L /img/l/avatars/ex.jpg Does this look like a good approach? -

How to designate a template tag element in custom template filter? (Django 2.1)

Search engine code in view.py: def query_search(request): articles = cross_currents.objects.all() search_term = '' if 'keyword' in request.GET: search_term = request.GET['keyword'] articles = articles.annotate(similarity=Greatest(TrigramSimilarity('Title', search_term), TrigramSimilarity('Content', search_term))).filter(similarity__gte=0.03).order_by('-similarity') context = {'articles': articles, 'search_term': search_term} return render(request, 'query_search.html', context) HTML template for search results: <ul> {% for article in articles %} <li><a href="{% url 'search:article_detail' article.ArticleID %}">{{ article }}</a></li> <p> {{ article.Content|highlight: search_term }} </p> {% endfor %} </ul> Custom filter: @register.filter def highlight(text, search_term): text = article.Content return mark_safe(text.replace(search_term, "<span class='highlight'>%s</span>" % search_term)) I get the error message "highlight requires 2 arguments, 1 provided". I assume this is because I am not designating the template tag element article.Content right. How can I do it properly? -

Group private messages in Django by users
I have built a private messaging system for registered users in Django, and I have a small issue. I cannot think of a way to group the messages by users. The image below shows the messages between two users. This is the conversation as seen by the user karolann. You can see that it does not group the messages correctly. The sentences "Hello Susan" and "Those two modules are quite challenging" should come after the last sentence - "Text me when you online.". Right now, the messages are grouped by the sender. If I group them by the receiver, it still does not work properly. It would need something that is common for both like a conversation id or something. So my question is: How do I create conversations? I want all the messages between two users to be in the same place. My models.py is as follows: My views.py is as follows: And lastly, my template: -

Django Form Doesn't Save to Table

How can I build a Django template filter that displays text surrounding a certain word? (Django 2.1)
I am building a search engine and want my search results to contain a short text blob that shows the keyword highlighted in its context, just like Google. For example, if the keyword is "Linux", I want my text blob to be something like "Get a Linux computer: no need to remove (and pay for) all the software you can't trust! The following vendors sell machines preinstalled with ..." So far, I've only found a filter mechanism to limit the amount of characters shown in the text blob, but I don't know how to restrict these characters to the characters surrounding the keyword. Any idea? My template: <div id="results-list" class="container"> <ul> {% for article in articles %} <li><a href="{% url 'search:article_detail' article.ArticleID %}">{{ article }}</a></li> <p> {{ article.Content|slice:":255" }} </p> {% endfor %} </ul> </div> My code for the search engine: def query_search(request): articles = cross_currents.objects.all() search_term = '' if 'keyword' in request.GET: search_term = request.GET['keyword'] articles = articles.annotate(similarity=Greatest(TrigramSimilarity('Title', search_term), TrigramSimilarity('Content', search_term))).filter(similarity__gte=0.03).order_by('-similarity') -
Server Error 500 in deploy Django to Heroku
So, I have a problem with a Django project I deployed to Heroku. I have finally been through the whole process of deploying the project resolving loads of errors. Now that the site is correctly deployed i have difficulties with my login app (that works perfectly fine on local host). Whenever I try to Register or login a user (or login in the admin page), i get a Server 500 error (You can try yourself at the link Universalvvfamily.herokuapp.com), but i can't understand why... What should I show you about my code so that you can help me? Thank you very much in advance -
Django send_mail giving NoneType Error with RequestFactory, But Not When Running Code Outside of Views (Test Code Included)
So I am having issues with my website in production and figured it was something with Nginx while in production. But I have boiled it down to another issue, that I am not quite sure how to define. The issue at hand is when using the send_mail function in Django (1.10.x). I can send emails perfectly when I run my function code from the terminal, just by typing it out while in a python shell. But when I try to run it using RequestFactory and running the given function with the request, I get an odd error. This error on my terminal screen is much more clear than the blank 500 server error I receive on my website. I have tried different email setups, even changing the email backend to console in the settings, and nothing is working. Code that works, after opening up my shell ./manage.py shell_plus >>> from django.core.mail import send_mail >>> name = 'Test User' >>> contact_email = 'testing@test.com' >>> contact_phone = '123-456-7890' >>> subject = 'Message from: %s, %s' % (name, contact_phone) >>> message = 'This is a test being sent from the backend console.' >>> to = 'user@test.com' # changed for anonymity >>> send_mail(subject, message, … -
Django: access from different network
I made a django server, which I ran by the command: python3 manage.py runserver 0.0.0.0:8000 When I try to connect to the server from the same computer using the localhost:8000 everything works fine :) However, when I try to connect to the server using server_ip:8000 from another computer, I get the response: ERR_CONNECTION_TIME_OUT. ( The server ip is configured in ALLOWED_HOSTS ) Any ideas how to solve this problem or what might be causing it? :)
