Cannot call QuerySet with a ForeignKey in Django
Version Mac OS : 10.15.6 Django : 3.7.6 What I want to do Get all Want_Items that are had by a specific user Hello, I'm a beginner to Django. I am trying to create an app that each can exchange their items. I created models, User, Parent_Item, Want_Item, Give_Item. And I set relations between them like below. User - Parent_Item => One To Many Parent_Item - Give_Item => One To Many Parent_Item - Want_Item => One To Many I succeeded in getting all parent_item that one user has. However, I cannot get want_item for some reason.

Django-Import-Export: Import Error - AttributeError: 'str' object has no attribute 'year'
I'm trying to use the django-import-export package to import a csv into my django model. the csv is very simple, a header row and the one row of values. there are two fields on the csv that are defined in the model as DateField's #models.py edit_date = models.DateField(verbose_name="Edit Date", blank=True, default="1970-01-01") premiere_date = models.DateField(verbose_name="Premiere Date", null=True, blank=True) there are another set of DateTime.Field's in the model that are not included in the csv file.

I've been through the docs and searched stack overflow, but I can't find a clear explanation of how to handle imports with the import-export package. #admin.py from datetime import … -
Does the django-rest-framework provide an admin site to manage models?
I'm looking to setup a REST API server with django, and googling suggests this is best done using the django-rest-framework. The API will return objects stored in a database, and I would also like to be able to add/modify the objects in the database using the django admin site. However, looking at the django-rest-framework documentaion, I see no reference to the admin site (I did find things about "AdminRenderer", but it looked like this isn't what I want). Simply, does the django admin site exist for a django-rest-framework project? -

I am trying to understand each step of the Pinax-teams models.py file (https://github.com/pinax/pinax-teams/blob/master/pinax/teams/models.py).

Filtering elements from Django database on two conditions
I want to select elements from my Django database on two conditions - whether the boolean value "used" is true and whether or not the "dateUsed" is within the last 20 days. However, my current filter statement is returning an empty QuerySet, even though there should be elements that meet both conditions. Am I filtering the elements correctly? I've attached the code that filters the elements, the definitions of my models, as well as the block of code that changes the value of "used" once the model elements have been displayed on my site. Filter: def pastSongs(request): window = datetime.now().date() - timedelta(days=20) songHistory = Song.objects.filter(used = True).filter(dateUsed__gt = window) ent = {} ent["ent"] = songHistory return render(request, 'rollingStone/songs.html',ent) Models: class Song(models.Model): rank = models.IntegerField() artist = models.CharField(max_length=100) title = models.CharField(max_length=100) cover = models.URLField() writers = models.CharField(max_length=100) producers = models.CharField(max_length=100) releaseInfo = models.CharField(max_length=100) description = models.TextField(max_length=3000) used = models.BooleanField(default=False) dateUsed = models.DateField(auto_now=True) Changing "used" field: 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() -

Is there an elegant way to export a Bootstrap-Studio project to a folder of lovely Django templates?
Dear wise and experienced spirits of StackOverflow, I am turning to thee in deep despair. My teacher gave me the honourable task to design a data-administration interface for our school paramedics. Somehow experienced in Python through machine learning I planned on writing the backend of the website with Django, as I did not have any interest in learning a fully new language / framework in such short time. Because of me being quite a greenhorn when it comes to WebDev, I remembered owning a license for Bootstrap-Studio through GitHub-Edu. As you might guess, I now have a fairly pretty frontend with all those forms I needed, but am unable to convert it into these Django templates that I need even more. I reeeeaaaaally hope that there might be any chance of getting this project done as ASAP as possible (see what I did there, huh?), because I am really running out of mental fuel these days. Yes, I might be a fool, but there are so many deadlines to hit... :( Thank you very much in advance, every tiniest bit of help is higly appreciated. Thus indebted to you for your pains taken for me, I bid you farewell. -
What is the difference in localhost:8000 and http://127.0.0.1:8000?
I am running a Django project with react redux (trying to implement authentication system) and the very weird thing i observed that my site is rendering properly when i use localhost:8000 or http://127.0.0.1:8000. But when i m trying to login/signup (ie trying to send post request) then it working only when i use localhost:8000, and giving some error when using http://127.0.0.1:8000. One of the error when using http://127.0.0.1:8000 is shown below. However i have seen this and found localhost will often resolve to ::1, the IPv6 loopback address. But i am getting is it related to this or not ? And whether localhost:8000 and http://127.0.0.1:8000 is same or not ? Please try to answer in simple words because I have not much knowledge of internet protocol or networking. -
Django Admin StackedInline
I have a stackeinline Django admin. This is used to add multiple products for a shop. However, when I click on 'Save and add another' it sometimes shows 'Entity too large', even when the files are below the allowed size, or sometimes it shows 'DATA_UPLOAD_MAX_NUMBER_FIELDS' error. My question is, does Django stackedinline admin save each and every object each time we click on save? If no, then what could be the reason for this error? -
Creating instances of 2 related models using nested serializer in Django
I am a newbie at Django and I have come across this problem with my code. I have a Custom User Model and an Account model which are related by many-to-many field. During SignUp a user is asked to either create an Account or not ( join other account through a link ). If the User creates an Account then he is the owner of the account and other Users can join the account.(Did not finish the code for ownership) One User can be a part of several accounts at the same time. Creation of Account(or not) and the User takes place in the Signup view. I read up about the nested serializer in the documentation and i think this should create the two models instances. How to create relationships in one view using nested serializers? Other Approaches to solve the issue? Models class Account(models.Model): AccountName = models.TextField(max_length=100, blank=False, null=False) class User(AbstractBaseUser): AccountName = models.ManyToManyField(Account) CreateAccount = models.BooleanField(blank=False, null=False) EmailId = models.EmailField(max_length=128, blank=False, null=False, unique=True) is_admin = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) USERNAME_FIELD = 'EmailId' REQUIRED_FIELDS = ['AccountName', 'CreateAccount',] # Implemented the other req. functions objects = MyAccountManager() Serializers class AccountCreationSerializer(ModelSerializer): class Meta: model = … -
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

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",)} -

When I look at the log files, I see this: "Traceback (most recent call last): File "/env/lib/python3.7/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker worker.init_process() File "/env/lib/python3.7/site-packages/gunicorn/workers/gthread.py", line 92, in init_process super().init_process() File "/env/lib/python3.7/site-packages/gunicorn/workers/base.py", line 119, in init_process self.load_wsgi() File "/env/lib/python3.7/site-packages/gunicorn/workers/base.py", line 144, in load_wsgi self.wsgi = self.app.wsgi() File "/env/lib/python3.7/site-packages/gunicorn/app/base.py", line 67, in wsgi self.callable = self.load() File "/env/lib/python3.7/site-packages/gunicorn/app/wsgiapp.py", line 49, in load return self.load_wsgiapp() File "/env/lib/python3.7/site-packages/gunicorn/app/wsgiapp.py", line 39, in load_wsgiapp return util.import_app(self.app_uri) File "/env/lib/python3.7/site-packages/gunicorn/util.py", line 358, in import_app mod = importlib.import_module(module) File "/opt/python3.7/lib/python3.7/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1006, in _gcd_import File "<frozen importlib._bootstrap>", line 983, in _find_and_load File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 677, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 728, in exec_module File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed File "/srv/main.py", line 1, in <module> from tanuki.wsgi import application File "/srv/tanuki/wsgi.py", line 11, in <module> from django.core.wsgi import get_wsgi_application ModuleNotFoundError: No module named 'django'" I have Django installed on my virtual environment and my sys.path includes the path to the site-packages. Is there something else I am missing? -
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
