Django ' One To Many ' Relationship (Comment on a joke)
thought I'd make a website, where people can upload jokes and comment on different ones, basic functions so far. The only issue I am facing is once I create a comment, I cannot automatically assign it to a joke, I have to select the joke manually that I want to comment on, how do I do that using the current many to one relationship that I have now. Current thoughts... Use this from the jokes model that I'm passing around in the urls to select the joke and assign to the comment this way (Not sure how to do this) Here are my models: from django.db import models from django.utils import timezone from django.urls import reverse class JokeListItem(models.Model): title = models.CharField(max_length=100, null=True) content = models.TextField(null=True) date_posted = models.DateTimeField(null=True, default=timezone.now) comment = models.CharField(max_length=100,null=True) def __str__(self): return self.title def get_absolute_url(self): return reverse('joke-home') class Comment(models.Model): content = models.CharField(max_length=100,null=True, blank=True) joke = models.ForeignKey(JokeListItem, blank=True, null=True, on_delete=models.CASCADE,related_name='comments') def __str__(self): return self.content def get_absolute_url(self): return reverse('joke-home') Here are my views: from django.shortcuts import render from .models import JokeListItem, Comment from django.views.generic import CreateView, DeleteView, DetailView, UpdateView from django.shortcuts import get_object_or_404 # Create your views here. def home(request): all_joke_items = JokeListItem.objects.all() return render(request, 'website/home.html', {'jokes': all_joke_items}) class … -
Handling html special chracter in django url
This is my django rest framework view: class NewsArticleViewSet(viewsets.ReadOnlyModelViewSet): queryset = [] serializer_class = NewsArticleSerializer pagination_class = None def get_queryset(self): slug = self.request.query_params.get('news', None) if slug: news = News.objects.filter(slug=slug) return news return [] which is working perfectly except when I pass html special chracter in url like this one: ?news=example/2020/4/4/&apos;53-lorem-ipsum&apos; its returning nothing; because self.request.query_params.get('news', None) parsing as example/2020/4/4/ not full string example/2020/4/4/&apos;53-lorem-ipsum&apos; Here is value of self.request.query_params for debugging: <QueryDict: {'news': ['example/2020/4/4/'], 'apos': ['', ''], '53-lorem-ipsum': ['']}> How to fix this problem ? -
How to run a Django Query to filter from a list of values?
I have a list that looks like this - Let's call this list "links" ['https://crucible05.cerner.com/viewer/cru/CCS-28483', 'https://crucible05.cerner.com/viewer/cru/CCS-28520', 'https://crucible05.cerner.com/viewer/cru/CCS-28779'] My Python model, reviewComments looks like this - class reviewComments(models.Model): reviewID = models.CharField(max_length=20, blank=True) commentID = models.CharField(max_length=20, primary_key=True) solution = models.CharField(max_length=50) comment = models.TextField() dateCreated = models.DateField() type = models.CharField(max_length=20, blank=True) crucibleLink = models.URLField(blank=True) authorID = models.CharField(max_length=20) reviewerID = models.CharField(max_length=20) def __str__(self): # pragma: no cover return self.commentID In reviewComments, the field crucibleLink field contains several elements in the database like this - ['https://crucible05.cerner.com/viewer/cru/CCS-24654#CFR-2484153', https://crucible05.cerner.com/viewer/cru/CCS-26041#CFR-2549576 ] Notice the extra #CFR part in each of these.. I need to run a Django query to filter out the "links" elements from the ones present in the database. I tried doing this - crucible_db = reviewComments.objects.values_list('crucibleLink', flat=True) for link in links: crucible_db = crucible_db.filter(crucibleLink__icontains = link) print(crucible_db) But this returns only one queryset and then several empty querysets like this - How do I go about doing this? Thanks -

How can I display images with the same height with CSS?
I have a dating website and I display lists of users with profile pictures. If the user doesn't have a profile picture, I display a specific image. Here is the code: @register.inclusion_tag(filename='accounts/profile_picture.html', takes_context=True) def profile_picture(context, user, geometry, with_link=True, html_class=''): context = copy.copy(context) geometry_splitted = geometry.split('x') width = geometry_splitted[0] if (len(geometry_splitted) == 2): height = geometry_splitted[1] else: height = geometry_splitted[0] context.update({ 'user': user, 'geometry': geometry, 'width': width, 'height': height, 'with_link': with_link, 'html_class': html_class, }) return context profile_picture.html: {% thumbnail user.photo.file geometry crop='center 20%' as image %} <img src="{{ image.url }}" alt="{{ user.name }}" width="{{ image.width }}" height="{{ image.height }}" class="img-fluid {{ html_class }}" /> {% empty %} <img src="{% static 'speedy-core/images/user.svg' %}" alt="" width="{{ width }}" height="{{ height }}" class="img-fluid {{ html_class }}" /> {% endthumbnail %} CSS: .img-fluid { max-width: 100%; height: auto; } But the problem is, because of this height: auto; thing, users without a profile picture have profile pictures higher than users with profile pictures. I want to display all users with the same height, and if necessary, display a smaller width for users without a profile picture (which displays speedy-core/images/user.svg as their profile picture). If possible, without changing the file user.svg itself. How do I do … -

Optionally link a model to another model via a foreign key
I have a Django application where registered users can add, through an input form, details of performances of their music ensemble. This application also has a a section for composers, where they add their own composition. I'm using a custom user model, with profiles linked to user accounts: class User(AbstractBaseUser): email = models.EmailField(verbose_name="email", unique=True, max_length=255) first_name = models.CharField(max_length=30, blank=True, null=True) [...] class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) [...] This is my 'composition' model: class Composition(models.Model): title = models.CharField(max_length=120) # max_length = required composer = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE ) [...] And this is my 'performance' model. The performance information links to the piece performed (performed): class Performance(models.Model): performed = models.ManyToManyField(Composition, blank=True) [...] So far, so good. Now, I'd like the performers to be able to add pieces by composers who are not (yet) registered to the website. Let's say that the performer performed a piece by John Lennon and is adding information about that performance. So, the performer will need to be able to add both John Lennon, his composition, and link the two. The most important bit is: if the ghost of John Lennon tomorrow wants to register to the website, the administrator of the website will need to be … -
Pytest Not Deselecting Certain Tests (but should be in pytest.ini)
I've got a test suite setup and have been using pytest (which I find so fantastically helpful for testing Django projects, which this is). I also am using pytest-django on this project. To give some background: I am trying to do some integration testing with a Headless Browser and have pytest ignore certain tests that are used where I am using a standard browser (not-headless); I'd like to deselect those tests using a real, visual browser so that they don't trigger in my CI/CD pipeline. Given the example pytest.ini below if I run: pytest launcher it shows as I would expect that there is 1 test being deselected (the StandardBrowserTestCases class only has 1 test in it). However, if I run: pytest other_app (which also has a StandardBrowserTestCases class) it does not show anything being deselected and StandardBrowserTestCases is ran with the other tests and not deselected. [pytest] addopts = --nomigrations --cov-config=.coveragerc --cov=my_project --cov=other_app --cov=launcher --cov=people ; # Ignore the StandardBrowserTestCases - these are only used for local ; # development / visual debug and contain no real valuable tests --deselect=other_app/tests/test_integrations.py::StandardBrowserTestCases --deselect=launcher/tests/test_integrations.py::StandardBrowserTestCases --deselect=people/tests/test_integrations.py::StandardBrowserTestCases --junitxml=./test-results/junit.xml --cov-report html:./test-results/htmlcov --html=./test-results/test_results.html --self-contained-html DJANGO_SETTINGS_MODULE = my_project.unit-test-settings python_files = tests.py test_*.py *_tests.py Question(s): Am I using … -
Django child model with OneToOne parent does not inherit parent's fields?
I have a parent classs Dish and a child Pizza that inherits from Dish. They have a 1to1 relationship and I wrote them as follows: class Dish(models.Model): PIZZA = 'PIZZA' SUB = 'SUB' PASTASALAD = 'PASTASALAD' PLATTER = 'PLATTER' TYPE_CHOICES = ( (PIZZA, 'Pizza'), (SUB, 'Sub'), (PASTASALAD, 'PastaSalad'), (PLATTER, 'Platter') ) name = models.CharField(max_length=64, blank=True) type = models.CharField(max_length=64, choices=TYPE_CHOICES, blank=True) size = models.CharField(max_length=1, choices=SIZE_CHOICES, default=SMALL, blank=True) price = models.DecimalField(max_digits=6, decimal_places=2, default=None) def __str__(self): return f"{self.name} {self.size} - Price: ${self.price}" class Pizza(Dish): dish = models.OneToOneField(Dish, on_delete=models.CASCADE, related_name="dish_id_pizza", parent_link=True) REGULAR = 'REGULAR' SICILIAN = 'SICILIAN' STYLE_CHOICES = ( (REGULAR, 'Regular'), (SICILIAN, 'Sicilian'),) style = models.CharField(max_length=7, choices=STYLE_CHOICES, default=REGULAR) topping_count = models.IntegerField(default=0, validators=[MaxValueValidator(5), MinValueValidator(0)]) def __str__(self): return f"{self.size} {self.style} pizza with {self.topping_count} toppings: ${self.price}" Now I have a Dish object with ID=17 and a price of 21.95, type=Pizza, size=Small, type=Regular. I now try to create the corresponding Pizza object as follows: >>> parent=Dish.objects.get(pk=17) >>> new_17_pizza = Pizza(dish=parent, topping_count=2, style="Regular") >>> new_17_pizza.save() I would assume that all Dish fields and values are inherited, i.e. I don't have to repeat them, but I get: sqlite3.IntegrityError: NOT NULL constraint failed: orders_dish.price Why is that? I know I am not allowing blank=True for the price in Dish, but … -

Customizing default auth form in Django for html template
I'm trying to use the CSS from an HTML template I downloaded online to work in my default Django login form, and I gather that to imbue {{ form.username }} with any styles, you must create a custom LoginView in forms.py and modify that as if it were any other form using attrs={}. I have already done what was suggested in this question before anyone says this is a duplicate. class UserLoginForm(AuthenticationForm): def __init__(self, *args, **kwargs): super(UserLoginForm, self).__init__(*args, **kwargs) username = forms.CharField(widget=forms.TextInput( attrs={ 'class': 'input100', } )) password = forms.CharField(widget=forms.PasswordInput( attrs={ 'class': 'input100', } )) The name of the CSS style I'm trying to apply to the username (and password) text fields is "input100" but the username and password don't seem to be affected by anything I'm putting in forms.py. In fact, even if I take out the username and password fields in the above file, it still works the same, so clearly changes to forms.py aren't reaching the template (but the template is using UserLoginForm fine as if I take the whole thing out it crashes). change to urls.py: urlpatterns = [ path('', subsmems, name='subsmems'), path('accounts/', include('django.contrib.auth.urls')), path('signup', signup, name='signup'), path( 'login/', views.LoginView.as_view( authentication_form=UserLoginForm, ), name='login' ) ] html … -

Using the attribute value from IntegerField in another object attribute
So I am trying to learn django, and I am trying to enable image resizing from an image uploaded which is then assigned to an object via admin. I am using the django-stdimage lib. The idea is an instance as follows can be summoned: class Website_Post(models.Model): title = models.TextField(default='Enter title') intro = models.TextField(default='Enter post') image_width = models.IntegerField(validators=[MaxValueValidator(1000), MinValueValidator(0)], default=300) image_height = models.IntegerField(validators=[MaxValueValidator(1000), MinValueValidator(0)], default=300) cover = StdImageField(upload_to='images/', variations={'full': {'width': image_width, 'height': image_height}},null=True) def __str__(self): return self.title And then in /admin the image proportions can be defined, with a max value and a min value, which is then applied to the selected image. My reasoning for this is that the StdImageField variations are not easily accessible once the object has been created, so this way they can adjusted, at least from the backend. However when running this code, the object cannot be created, as the following error is given: TypeError: '>' not supported between instances of 'int' and 'IntegerField' with the error at this point: @staticmethod def is_smaller(img, variation): return img.size[0] > variation['width'] \ # <--- error in this line or img.size[1] > variation['height'] which to me indicates that the IntegerField value does not appear as an integer when used in … -

django Multiple newtwork request to api cause unique violation error
So i have an API that takes a keyword and runs some logic, then inserts the data into Keyword table. The keyword model is: class Keyword(BaseModel): text = models.CharField(max_length=500, unique=True) key_id = models.CharField(max_length=20, null=True, blank=True) def __str__(self): return my_unicode(self.text) Now due to some bug in my frontend js code a api request was getting sent two times on a button click(not a major issue). But in the backend during the processing of the keyword following code runs which was creating UniqueViolation error: def get_data_for_keyword(key, region_id, language_id): # key is the keyword text that we need to save into db which is coming from network request # Some code keyword = Keyword.objects.filter(text__iexact=key) if keyword.exists(): keyword = keyword[0] # some code else: keyword = Keyword(text=key) keyword.save() # some code Scenrio: Two request come with the same keyword(due to the js bug). Expected behaviour: Both request check the existence of that keyword in DB, the one that runs first doesn't find it in DB creates it and the other one finds it in DB and further processing happens. But whats happening is somehow both request are getting executed simultaneously and both when filtering are not finding that keyword and both are trying to … -

How does Django knows which template to render when?
I am on 4th chapter the book Django 3 by example and I noticed one thing that we are only creating views from Django's authentication framework but we are not telling those views which template to render when. For example, how does my application would know that it needs to only render the logged_out.html template when we try to access the logout view? If I try to change the name of the file from logged_out.html to loggedout.html then it takes me to the Django's admin logout page. Why? -
