Setting up gitlab CI with simple django project
I have a very simple django project with a few unit tests on it and I would like to set up Gitlab to run those tests evry time I make a new commit. I use sqlite3 for my database (I plan to change later, but for now I want to keep it simple) and I stored some of my settings variable in a .env file. Here is my .gitlab-ci.yml file (I used the default file proposed by gitlab and removed what I thought I didn't need) : image: python:latest variables: SECRET_KEY: "this-is-my-secret-key" DEBUG: "True" ALLOWED_HOSTS: "['*']" DB_ENGINE: "django.db.backends.sqlite3" DB_NAME: "test_database.sqlite3" STATIC_URL: "/static/" cache: paths: - ~/.cache/pip/ before_script: - python -V - pip install -r requirements.txt test: script: - cd backend - python manage.py test but when I commit, I get this error $ python manage.py test /usr/local/lib/python3.9/site-packages/environ/environ.py:628: UserWarning: /builds/romainros/ynoverflow/backend/ynoverflow/.env doesn't exist - if you're not configuring your environment separately, create one. warnings.warn( Creating test database for alias 'default'...

translate rna to protein
I am currently working on a rna to protein translator. To do that, I've created a class that does two things. Firstly, you input a dna chain and it gets translated into rna (this part works perfectly) Secondly, you get the rna chain translated into a protein (this part doesn't work). Here's the code for the class: class TranslatorView(View): template_name = 'main/translated.html' rna_mapper = { "a": "u", "t": "a", "c": "g", "g": "c" } amino_mapper={ "aat": "Asparagine", "aac": "Asparagine", "aaa": "Lysine", "aag": "Lysine", "act": "Threonine", "acc": "Threonine", "aca": "Threonine", "acg": "Threonine", "agt": "Serine", "agc": "Serine", "aga": "Arginine", "agg": "Arginine", "att": "Isoleucine", "atc": "Isoleucine", "ata": "Isoleucine", "atg": "Methionine", "cat": "Histidine", "cac": "Histidine", "caa": "Glutamine", "cag": "Glutamine", "cct": "Proline", "ccc": "Proline", "cca": "Proline", "ccg": "Proline", "cgt": "Arginine", "cgc": "Arginine", "cga": "Arginine", "cgg": "Arginine", "ctt": "Leucine", "ctc": "Leucine", "cta": "Leucine", "ctg": "Leucine", "gat": "Aspartic", "gac": "Aspartic", "gaa": "Glutamic", "gag": "Glutamic", "gct": "Alanine", "gcc": "Alanine", "gca": "Alanine", "gcg": "Alanine", "ggt": "Glycine", "ggc": "Glycine", "gga": "Glycine", "ggg": "Glycine", "gtt": "Valine", "gtc": "Valine", "gta": "Valine", "gtg": "Valine", "tat": "Tyrosine", "tac": "Tyrosine", "taa": "Stop", "tag": "Stop", "tct": "Serine", "tcc": "Serine", "tca": "Serine", "tcg": "Serine", "tgt": "Cysteine", "tgc": "Cysteine", "tga": "Stop", "tgg": "Tryptophan", "ttt": "Phenylalanine", "ttc": "Phenylalanine", "tta": … -

Need help in Django Templates(using forloops)
I have 3 models namely Uses, Customer and Services.I have a query whose result is stored in the variable count. This is the query counts = Services.objects.filter(uses__customer=customer).annotate(times_used=Count('uses')) Each count[x] has a variable,x ranges from 0 to infinity. I have used a for loop in my html to get all the Services which I have passed through context in views. Now I need to get unique value of count for each service. How can I do this. Here is my html code <table class='table table-bordered' id='dataTable' width='100%' cellspacing='0'> <thead class='bg-primary'> <tr class='text-white'> <th>Service-Id</th> <th>Service-name</th> <th>Count</th> <th>Price</th> </tr> </thead> <tbody class="text-dark"> <tr>{% for service in services %} <td>{{ service.id }}</td> <td>{{ service.service_name }}</td> <td>#code for printing code# </td> <td>{{ service.price }}</td> </tr>{% endfor %} </tbody> </table> -
Django: How to pass a variable from view to forms?
I have view document and I would like to pass the my_number variable to DocumentForm in order to define what the form should look like. **views.py** def document(request, my_number): form = DocumentForm(request.POST or None) if form.is_valid(): form.save() return redirect(f'/index/') return render(request, 'document.html', {'form': form}) I think I have to pass the my_number for example in such a way: form = DocumentForm(request.POST or None, number=my_number) And in forms.py i have: **forms.py** class DocumentForm(ModelForm): class Meta: model = Document fields = [] person = Person.objects.get(id=number) choices = person.elements for choice in choices: if choice == '1': fields.append('choice_1') if choice == '2': fields.append('choice_2') But I don't know how to call number in: class Meta and in person = Person.objects.get(id=number). I will be very grateful for any suggestions. -
Django Bootstrap Accordion needs double click to expand
When I click the accordion the first time nothing happens. When I click it a second time, it opens and then closes immediately! It's like the second click sends both. Here's my template: {% for category in challenges_by_category_list %} {% if category %} <h2>{{ category.title }}</h2> <div class="accordion" id="accordion{{category.title}}"> {% for challenge in category.challenge_set.all %} <div class="card"> <div class="card-header" id="heading{{challenge.id}}"> <h2 class="mb-0"> <button class="btn btn-link btn-block text-left" type="button" data-toggle="collapse" data-target="#collapse{{challenge.id}}" aria-expanded="true" aria-controls="collapse{{challenge.id}}"> {{ challenge.question_text }} </button> </h2> </div> <div id="collapse{{challenge.id}}" class="collapse in" aria-labelledby="heading{{challenge.id}}" data-parent="#accordion{{category.title}}"> <div class="card-body"> Anim pariatur cliche reprehenderit, enim eiusmod high </div> </div> {% endfor %} </div> {% endif %} {% endfor %} I wondered whether it's something to do with including bootstrap twice?

How to retrieve necessary fields from ModelForms and pass them to views.py properly?
Short background of whole idea: I'm trying to create landing page and for backend I use Python/Django3 framework. I need to create form with such fields as name, surname, email, mobile number and address of customer. I've decided to save all the information that the user enters in the database, and also send it to my email. In order to connect database to forms I use ModelForms in forms.py section (all the required code will be shown below). In order to connect my email to form I use send_mail function from django.core.mail. So when a user fills out his form, he is redirected to the 'thank you' page and all the information from the form is saved in the database and sent to my email. But when I finally wrote the code and started to test functionality, I found out that when I hit 'submit' form button, error <type object 'ClientInfoForm' has no attribute 'cleaned_data'> is raised. I suppose, that method cleaned_data is wrong in my case and I have to replace it with something else but I don't know with what exactly. All the code will be placed below and any help will be helpful. Thank you! Models.py file … -

DRF ManytoMany filtering on related model, in subquery?
There are two models, a Page model and a Banner model, which are manyToMany related. The parameters API is twitched, which returns a list of pages and banners for each page. The Banner model has a field is_show by which you need to additionally filter the list of banners, i.e. in the admin panel, the banner can be selected for the model, but if is_show = False, then you do not need to return it to the API. views class PagesListView(generics.ListAPIView, viewsets.GenericViewSet): queryset = Page.objects.all() serializer_class = PageSerializer models class Banner(models.Model): title = models.CharField(verbose_name='Заголовок', max_length=255, null=True, blank=True) is_show = models.BooleanField(verbose_name='Управление отображением', null=False) pages = models.ManyToManyField( Page, blank=True, related_name='banners') class Page(models.Model): name = models.CharField(max_length=255, null=True, blank=True) serializers class BannerSerializer(serializers.ModelSerializer): class Meta: model = Banner fields = '__all__' class PageSerializer(serializers.ModelSerializer): banners = BannerSerializer(read_only=True, many=True) class Meta: model = Page fields = '__all__' The question is how to filter Banner by is_show field? If you just override the queryset for the view like this: queryset = Page.objects.filters(banners__is_show=True) then this is not the desired behavior. In this way, I am filtering the Page list, and I need to "wedge" into filtering the Banner list. -
ForeignKey to specific queryset django
Is there a way to refer to specific object of Model? Suppose I have some models like below: # models.py class VehicleCategoryCode(models.Model): category = models.CharField(max_length=5) name = models.CharField(max_length=20) class Code(models.Model): category = models.ForeignKey(VehicleCategoryCode, on_delete=models.CASCADE) index = models.CharField(max_length=4, blank=True) label = models.CharField(max_length=50) order = models.CharField(max_length=20, blank=True) is_active = models.BooleanField(default=True) # pay attention to the Model class Vehicle(models.Model): label = models.CharField(max_length=80) model = models.CharField(max_length=30) Currently Vehicle is not linked to any model. Now Code model is ForeignKey to VehicleCategoryCode, which has two objects. In the VehicleCategoryCode the first object label (for convenience sake) will be referenced by Vehicle.label, and the second object model (once again for convenience) will be referenced by Vehicle.model. So each field in Vehicle can refer to the same model, but different objects. So basically I'm wondering if something like the pseudo code below can be achieved anyhow. class Vehicle(models.Model): label = models.ForeignKey(VehicleCategoryCode__name='label', on_delete=models.CASCADE) model = models.ForeignKey(VehicleCategoryCOde__name='model', on_delete=models.CASCADE) Any suggestion or advice would be appreciated. Thank you. -
I want to make a payment system
I am trying to make a payment system.In my site I have a virtual coin called C Coin. So whenever customer will try to make payment with c coin the product can be bought with c coin just like other payment process. For example a product price is 2000 $ and a customer has 2000 c coin in his account when he will try to buy with c coin the logic will be like this (using my imagination) if customer has enough balance to buy he can purchase, his balance will be like this (total price of product - balance). i have this method in my head but cant transform this method to reality. Here is my views.py class Index(View): def get(self, request): cart = request.session.get('cart') if not cart: request.session['cart'] = {} #products = None products = Product.get_all_products() cats = Category.get_categories() brands = Brand.get_brands() sliders = Slider.objects.all() offers = Offer.objects.all() categoryID = request.GET.get('category') brandID = request.GET.get('brand') if categoryID: products = products.filter(category__id=categoryID) if brandID: products = products.filter(brand__id=brandID) args = { 'products': products, 'cats': cats, 'brands': brands, 'sliders': sliders, 'offers': offers } return render(request, 'Home/index.html', args) def post(self, request): product = request.POST.get('product') cart = request.session.get('cart') remove = request.POST.get('remove') if cart: quantity = … -

Specifying user ID in Django
I have this model where I calculate different values based on certain fields. For example, when I calculate the total, I use the field price and * it with the quantity field. When I want to get the margin, I take the calculated total and deduct it from a field in a different class known as sales. What has been hard to implement for me, is how to automatically get the user id, such that, when the deduct function is called, it deducts from that user and not the previous entry.

Why doesn't the MathJax preview show when using ckeditor and Django?
I'm currently trying to create a simple website using Django, with ckeditor for form fields. I would also like to integrate some Mathematics into my forms, hence why I downloaded the Mathematical Formulas plugin for ckeditor.

Django Custom login using email not working
I am trying to log a user in via email in django, everything is working fine(code wise), no errors and functions execute in a right manner. However, when I perform a check in the template it always return false. Here is my code: authenticate_user.py def authenticate(self, request, email=None, password=None): try: user = User.objects.get(email=email) except User.DoesNotExist: messages.add_message(request, messages.INFO, 'Email or Password is not correct.') print("User not found") return None else: user_password_is_valid = check_password(password, user.password) if user_password_is_valid: print("User found") return user else: messages.add_message(request, messages.INFO, 'Email or Password is not correct.') return None return None And for the handle_login view: def handle_login(request): context= { 'title': 'Login' } if request.method == 'POST': email = request.POST['email'] password = request.POST['password'] user = authenticate(request, email=email, password=password) print('User is', user) # This prints user no problem if user is not None: login(request, user) # No errors up to this point return redirect(reverse('mainapp:homepage')) else: return redirect(reverse('mainapp:homepage')) Now upon checking -> {% user.is_authenticated %} in the template.html it always return false. -
Problem in showing foreign key relation in view
I have a Land model with three relation which one of them is Letter and the model is: class Letter(models.Model): land = models.ForeignKey('Land', on_delete=models.DO_NOTHING) image = models.ImageField(null=True, upload_to=letter_image_file_path) text = models.TextField(null=True, blank=True) def __str__(self): return str(self.id) and its serializer is class LettersSerializer(serializers.ModelSerializer): class Meta: model = Letter fields = ('id', 'text', 'image', 'land',) read_only_fields = ('id',) and Land serializer is: class LandSerializer(serializers.ModelSerializer): utm_points = UTMPointsSerializer(many=True, read_only=True) letters = LettersSerializer(many=True, read_only=True) their views are : class BasicViewSet(viewsets.ModelViewSet): authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticated,) class LandViewSet(BasicViewSet): serializer_class = LandSerializer queryset = Land.objects.all() class UTMPointViewSet(BasicViewSet): serializer_class = UTMPointsSerializer queryset = UTMPoint.objects.all() class LettersViewSet(BasicViewSet): serializer_class = LettersSerializer queryset = Letter.objects.all() but when I send GET request it doesn't show letters field: here is the response: { "id": 1, "utm_points": [] } although utm_points and letters are exactly the same but they have different results. Land model has user relation which I removed it as simplicity. After some trials and errors I have no idea why the result does't have letters field. -
