Rendering ForeignKey objects in template with Django
I'm having trouble rendering related objects in a template. I have a Page model, that has a ForeignKey relationship to itself to define parent-child relationships. class Page(BaseModel): title = models.CharField( max_length=280, blank=False, null=False, ) description = models.CharField( max_length=280, blank=False, null=False, ) slug = models.SlugField( blank=False, null=False, ) is_home = models.BooleanField( default=False, ) is_parent = models.BooleanField( default=False, ) parent = models.ForeignKey( 'self', on_delete=models.PROTECT, default='Home', blank=True, null=True, related_name='children', ) content = RichTextField( blank=False, null=False, ) def __str__(self): return self.title def get_absolute_url(self): return reverse('page_detail', args=[str(self.slug)]) My views.py filters out non-parent pages: class PageListView(ListView): queryset = Page.objects.filter(is_parent=True, is_home=False) template_name = 'pages/page_list.html' context_object_name = 'page' But when it comes to rendering 'child' objects in my template, I'm stuck. I've figured that I need a loop within a loop (first for parent pages, second for child pages per parent page), but can't get the second loop to work. Here was my latest attempt, which got me a "'Page' object is not iterable" error. {% extends '_base.html' %} {% block content %} <div class="container"> {% for page in page %} <p>{{ page.title }}</p> {% for children in page %} <p>{{ page.title }}</p> {% endfor %} {% endfor %} </div> {% endblock content %} -
Passing html code from django and also from Javascript. How can I improve this?
I am making a twitter like social web page por homework. In one single page I have a form to write a tweet and enough space down there to show the tweets. To dynamicaly show them I`m using javascript fetch api to intercept the form and show them asynchronously: document.querySelector('form').onsubmit = (event) => { event.preventDefault(); fetch("", { method: 'POST', body: JSON.stringify({ body: document.querySelector('#new_message').value }), headers: { "Content-type": "application/json; charset=UTF-8", "X-CSRFToken": getCookie('csrftoken') } }) .then(response => response.json()) .then(result => { document.querySelector('#new_message').value = "" let div = document.createElement('div') div.innerHTML = ("<p>" + result.creation_date + "</p>" + "<a href='#'>" + result.username + "</a>" + ' said:' + '<br><br>' +"<div class='container'>" + "<p>" + result.body + "</p>" + "</div>"); div.style.cssText = "box-shadow: 0px 0px 2px; ; background-color:#F5F5F5; border-radius:10px; padding: 10px; margin: 5px;"; document.querySelector('#posts').append(div); }); } This dinamically shows the tweet when it`s written withouth reloading the page. But the problem comes when I want to display them when a user actually reloads the page, i mean, via a get method: if request.method == "GET": if request.user.is_authenticated: posts = Posts.objects.all().order_by('-creation_date') return render(request, "network/index.html", { "posts":posts }) else: return render(request, "network/login.html") This makes me handle the tweet html from the javascript code and also with django … -
Django site cycling between two views using schedule function
I created a site in Django that's supposed to cycle display a different song and album each day from Rolling Stone's top 500. However, if you refresh the site a few times, it eventually displays a different song and album than it originally did. What's more, it eventually goes back to the original song and album choices after a few more refreshes. Even stranger, it only switches between the same two song and album combinations, it never spontaneously picks a new song/album or adds a new set of songs and albums to the rotation. I've attached my views.py code responsible for displaying my home screen and loading a new song/album, let me know if you see the issue. entry = {"status": None} # Define song and Album of the day def reload(): # Change status of old song/album to used, and save the date that it was used if entry["status"] == "filled": currentSong = Songs.objects.get(entry["songEnt"].name) currentAlbum = Albums.objects.get(entry["albumEnt"].name) currentSong.dateUsed = datetime.now().date() - timedelta(days=1) currentAlbum.dateUsed = datetime.now().date() - timedelta(days=1) currentSong.used = True currentAlbum.used = True currentSong.save() currentAlbum.save() # If there is no old song, skip above step and begin adding new songs else: entry["status"] = "filled" song = Song.objects.filter(used = False).order_by("?").first() … -
Heroku Internal Server Error when Debug is False and collectstatic dosen't work - Django
I deployed an app to Heroku, which uses Postgres. Anytime I set Debug to True, it works fine. When I set it back to False, it gives an Error 500, Internal Server Error. I don't know why it does that. Does it have to do with staticfiles? I am using whitenoise for serving static files. Anytime I run heroku run python manage.py collectstatic, it gives me Running python manage.py collectstatic on djangotestapp... up, run.9614 (Free) 300 static files copied to '/app/staticfiles', 758 post-processed. When I then run heroku run bash, I find out that there is no staticfiles folder. Where exactly does it copy the static files to? Is this what is causing the Error 500?

How to stop Django from removing stop words in auto-generated slugs from prepopulated_fields?
I am developing a dictionary application using Django. I would like the URL to contain the dictionary headword currently being examined, and I would like this to happen automatically. Using Django prepopulated_fields, however, when I insert headword "this is my headword", I get the slug "my-headword". How can I tell Django to generate the slug "this-is-my-headword" instead? In other words, how do I stop it from removing stop words from auto-generated slugs? Here is my Headword class in models.py: class Headword(models.Model): headword = models.CharField(max_length=64, unique=True) slug = models.SlugField(max_length=32, unique=True) def __str__(self): return f"{self.headword}" And here is my HeadwordAdmin class in admin.py: class HeadwordAdmin(admin.ModelAdmin): fieldsets = [ (None, {"fields": ["headword"]}), ("URL", {"fields": ["slug"]}), ] inlines = [DefinitionInline] list_display = ("headword",) search_fields = ["headword"] prepopulated_fields = {"slug": ("headword",)} -

How to change this code to make sure the User can only send a follow request once and not multiple times?
Hey guys I have a model and a function to send follow request to other users and they will be accepting the request if the sender has to follow them. problem is I need to make sure that when the sender first sends a request, the button shouldn't show follow again, instead should show cancel option to delete that request. As of now the user can send requests again and again. These are the codes. def send_follow_request(request, username): user_from = request.user user_to = Account.objects.get(username=username) # is_requested = False send_request = notify.send(user_from, recipient=user_to, verb='has sent you a follow request', target=user_to) # is_requested = True return redirect('posts:userprofile', user_to.username) models.py class Contact(models.Model): user_from = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='rel_from_set', on_delete=models.CASCADE) user_to = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='rel_to_set', on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True, db_index=True) follow_status = models.CharField(choices=FOLLOW_STATUS, max_length=10) #USER_FROM IS THE ONE WHO IS FOLLOWING AND USER_TO IS ONE BEING FOLLOWED class Meta: ordering = ('-created',) def __str__(self): return f'{self.user_from} follows {self.user_to}' following = models.ManyToManyField('self', through=Contact, related_name='followers', symmetrical=False) #adding the above field to User Model class user_model = get_user_model() user_model.add_to_class('following', models.ManyToManyField('self', through=Contact, related_name='followers', symmetrical=False)) Thank you -
Django - 'QuerySet' object has no attribute 'künstler_set'
I have a relation between an artist and images. I want to show a single artist and his related images. I created two models for artist and image. Inside the image class I made a ForeignKey to artist: class Artist(models.Model): profilepic = models.ImageField( blank=True) surname = models.CharField(max_length=120) class Image(models.Model): image = models.ImageField() relArtist = models.ForeignKey(Artist, null=True, on_delete=models.SET_NULL) inside my views.py I tried to get the artist by ID (primaryKey) which is working perfectly but it didn't work with the images. def artistSingle(request, pk): artist = Artist.objects.filter(id=pk) images = artist.relArtist_set.all() return render(request, 'artists/artistSingle.html', { 'artist': artist, 'images': images, }) If I run the code it throws an error: 'QuerySet' object has no attribute 'relArtist_set' I dont know how to get the images which rely to the artist.

How to compare dictionary key and queryset value in Django Template
I'm trying to compare a dictionary key with query set variable in a Django Template. Both output correctly on their own, however, together I cannot compare the values. Django template {% for object in query_set %} {% for key, value in dictionary.items %} var key = {{ key }}; {% if key == query_set.name %} <h5> You get this value: {{ value }}</h5> {% endif %} {% endfor %} {% endfor %} What ends up happening is that key gets all the variable values instead of a singular value and it cannot properly compare. Output of key key var = output 1; key var = output 2; key var = output 3; I think I'm just missing a syntax error or maybe I need to write a custom html tag to do this? -

How to translate field name in Django?
I am writing a web app backend that need to reuse an existing REST API. The API has a list of configuration field in JSON looks like this: feature1.export.car.functionA feature1.export.car.functionB feature2.a.b.c Whereas it is a dot notation string and the value can be anything. I was planning to have several Django models that represent those fields base on the feature and each configuration field will be represented by each model field. I am planning to use verbose_name in the Field object to represent the actual Django model field so that I can do the mapping between the input field from the API and the Django model field: class Feature1(models.Model): export_car = models.CharField(verbose_name="feature1.export.car.functionA") class Feature2(models.Model): a_field = models.CharField(verbose_name="feature2.a.b.c") But I am not sure how to do the 1 to 1 mapping when I receive the request from the View class. Is there an easy way to do that in Django? -
