How to check if a Django arrayfield has data
I have a Django model for articles with an array field that sometimes has ids. id_list = ArrayField(models.CharField(max_length=10000), blank=True, null=True) I want to write a query that finds all the article objects that have data in the id_list. I tried the following, but it did not work. Article.objects.filter(id_list__isnull=False) What is the correct way to write this? Thank you. -
How can I make a button pull a specific piece of data from the database?
I am creating a restaurant web app using Django and Python. I am trying to use buttons to select menu items to be added to the order, and displayed in a text area along with their prices. Thanks! Here is the code for this section: HTML: <div class="row"> {% for Product in show_menu %} <div class="col-sm-5" style= "color:#EAEAEA"> <button type = "submit" class="btn btn-info btn-md" onclick = "input()">{{ Product.name }}: ${{ Product.price }}</button> <br><br><br> </div> {% endfor %} </div> <label for="order"><h2 style= "color:#EAEAEA"><u>Order Details</u></h2></label> <br> <form> <textarea readonly class="fixed-right" id="order" name="order" rows="10" cols="80"> </textarea> </form> Views.py: class HomeView(ListView): model = Product template_name = 'mis446/home.html' context_object_name = 'show_menu' Models.py: class Product(models.Model): name = models.CharField(max_length=100) price = models.IntegerField() def __str__(self): return self.name -
Second image not saving with serializer
I have 2 models that looks like this: class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice = models.CharField(max_length=120) class ChoiceImage(models.Model): choice = models.OneToOneField(Choice, on_delete=models.CASCADE, null=True) img = models.ImageField(upload_to='some-path/') A serializer for the ChoiceImage that looks like this: class ChoiceImageSerializer(serializers.ModelSerializer): img = Base64ImageField() class Meta: model = ChoiceImage fields = ('img',) And a ChoiceSerializer that looks like this: class CreateChoiceSerializer(serializers.ModelSerializer): choiceimage = ChoiceImageSerializer(many=False, required=False) class Meta: model = Choice fields = ('choice', 'choiceimage') def create(self, validated_data): image_uploaded = validated_data.get("choiceimage") if not image_uploaded["img"]: q = validated_data.get("question") if not q.choice_set.exists(): raise APIException("You must upload either an image or a cover.") else: img = q.choice_set.all()[0].choiceimage.img img2 = slice_image(img) validated_data["choiceimage"]["img"] = img2 image_validated_data = validated_data.pop('choiceimage') choice = Choice.objects.create(**validated_data) image_serializer = self.fields['choiceimage'] image_validated_data['choice'] = choice image_serializer.create(image_validated_data) Basically, the intention is this: A user creates 2 choices. If the user provides no image to the choices, then return an error. Else if the user provides only one image, split the image in half. Save one half to the first choice and the second half to the second choice. Lastly, if two images are uploaded then ignore the split image logic. My logic works fine with no image and two images. However, when I submit only one image, the … -

new python/django user here. i'm trying to set up a webpage that takes user input (e.g., an address) into a form, then passes it through a python script (in a separate.py file) before returning an output to the same webpage (e.g., the nearest traffic light). how would i go about making the connection between my views.py file and my script.py file in django? simplified code: views.py file input = form.cleaned_data.get('enter_address') script.py file print(input) -
Traversing a ManyToMany relationship to add to context in a Django DetailView
I asked a similar question recently about a different project. In that case (see Traverse multiple foreign keys in Django DetailView), I was able to follow the flow of Foreign Keys to make the needed connection when defining the view. In this case I need to traverse through a ManyToMany junction table, and I'm stymied. Here's an ER diagram of the relevant portion of my model. ┌────────────┐ ┌────────────┐ ┌───────────────┐ ┌────────────┐ │ │ ╱│ │ ╱│ │╲ │ │ │ Company │─────┼──│ Product │────┼──│ PersonProduct │──┼────│ Person │ │ │ ╲│ │ ╲│ │╱ │ │ └────────────┘ └────────────┘ └───────────────┘ └────────────┘ The purpose of this web site is to connect professional archers with the equipment and companies that sponsor them and display those connections. In this particular case, I have a detail view for a company. I've successful set it up for display all the products that the company sells. Now I want to display a list of all the archers that use one or more products from that company. I can't figure out how to span all the way from the company to the individuals who use those products. Here's the model, view, and template I'm working with. # models.py from … -
Django fetch firebase User UID
I'm using Pyrebase to fetch data from firebase in Django and so far it seems to be able to do everything but for some reason, I can't fetch the User UID from the authentication page in firebase. This is necessary for me to be able to do as all my user database nodes are save under the User UID from here. Here is my current attempt but the idToken doesn't return the User UID token = user['idToken'] print(token) -
Trying to use JQuery to fill out a form
I am working on a django project that shows a list of meals on the home page. Below each meal I want to include an order button that pulls up a popup field to enter the amount of orders for that meal you would like to place and then on clicking 'OK' submits a form that creates an order object. Image of List of Meals Currently, if you click on the button it creates an order where the number of meals ordered is 1. View def add_order(request, meal_slug, meal_restaurant, amount): meal = Meal.objects.get(slug=meal_slug, restaurant_slug=meal_restaurant) user = UserProfile.objects.get(user=request.user) order = Order.objects.create(meal=meal, customer=user, amount=amount, date=datetime.now()) order.save() return index(request) Html <ul class="list-group"> <li class="list-group-item">{{ meal.meal_name }}</li> <li class="list-group-item">{{ meal.description }}</li> <button class="order"><a href="{% url 'food_cloud:add_order' meal.slug meal.restaurant_slug %}">Order</a></button> </ul> JQuery $(document).ready(function() { $(".order").click(function() { var amount = parseInt(prompt("Please enter amount of orders" ,"0")) if (amount <= 0) { alert("Please enter integer greater than 0") } else { $.ajax({ url: "{% url 'food_cloud:add_order' meal.slug meal.restaurant_slug amount %}", type: "POST", }) } }) }) -
Uploading a signature with Django
I'm trying to create a signature field that will relate back to a model in django. I scoured everywhere and was finally able to get a jquery signature canvas within my project. But being that I know very little about jquery, I'm not sure how to get the created signature instance to tie to the model and upload directly to the media cdn. Right now I can upload a file, and I can save a signature to my local machine. But I can't do them together.

Python - How can we speed this up without modifying the body of the get_resource_identifier function
Suppose the get_resource_identifier function interrogates some cloud infrastructure to resolve the resource identifier from its name. Note that it takes a long time for the call to finish resolving the name. Now imagine that we need to resolve the resource by its name multiple times during deployment of infrastructure. How can we speed this up without modifying the body of the get_resource_identifier function? Remember, you have no control over how quickly the cloud provider can respond to your API call. import time def get_resource_identifier(name): time.sleep(1)#simulate the delay if name is 'foo': return 'L9UKvnomjq' if name is 'bar': return '7U9eyOv7M' return 'Not found' for _ in range(0,100): print(get_resource_identifier('foo')) print(get_resource_identifier('bar')) print(get_resource_identifier('foo')) print(get_resource_identifier('zoo')) print(get_resource_identifier('bar')) -
Django Rest FrameWork Add Model With User Foreign Key
I'm using Django version 3 and the Rest Framework, i have a model with a user foreignkey. so every time a model is saved the user also need to be saved. To be able to add or to edit a model via rest you need to be authenticated using token authentication. I'm using ClassBasedViews, the problem is that i can't find a way to add a model because in my serializer the field user is excluded because i don't want it to be editable. models.py: class Chambre(models.Model): local_id=models.PositiveIntegerField(unique=True) nom=models.CharField(max_length=255) user=models.ForeignKey(User,on_delete=models.CASCADE,blank='true') class Meta: unique_together = ('local_id', 'user',) serializers.py: class ChambreSerializer(serializers.ModelSerializer): class Meta: model = Chambre exclude =['user',] views.py: class ChambreListApi(APIView): """ List all chambres, or create a new chambre.

Displaying objects by categories in Django
I'm building an ecommerce app and I'd like to make a section that shows some featured items by category. I'm using three sliders that display those items; Each slider is a featured category and each item in the slider is a featured item. The problem is that I can't figure out how to assign the item to the proper slider. For example: I want to assign a JeansJacket to "Clothes and accesories" and display it. I tried this: {% for cat in categories %} <h1>{{ cat.cat_name }}</h1> <!--(carousel code in between)--> <div class="carousel-inner" role="listbox"> {% for item in featured_items %} {% if item.Categoría in cat.cat_name %} {{ item }} {% endif %} This is a simplified version of what I have, without the rest of the content. I just can't figure out how to iterate though the featured items and display them in the corresponding category. -

Django formset creates multiple inputs for multiple image upload
I am trying to create a simple post sharing form like this one. I'm using formset for image upload. But this gives me multiple input as you can see. Also each input can choose single image. But I'm trying to upload multiple image with single input. views.py def share(request): ImageFormSet = modelformset_factory(Images, form=ImageForm, extra=3) # 'extra' means the number of photos that you can upload ^ if request.method == 'POST': postForm = PostForm(request.POST) formset = ImageFormSet(request.POST, request.FILES, queryset=Images.objects.none()) if postForm.is_valid() and formset.is_valid(): post = postForm.save(commit=False) post.author = request.user post.save() for form in formset.cleaned_data: # this helps to not crash if the user # do not upload all the photos if form: image = form['image'] photo = Images(post=post, image=image) photo.save() return redirect("index") else: print(postForm.errors, formset.errors) else: postForm = PostForm() formset = ImageFormSet(queryset=Images.objects.none()) return render(request, "share.html", {"postForm": postForm, 'formset': formset}) share.html <form method="POST" id="post-form" class="post-form js-post-form" enctype="multipart/form-data"> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} {{ form }} {% endfor %} </form> if you need, forms.py class PostForm(forms.ModelForm): class Meta: model = Post fields = ["title", "content"] def __init__(self, *args, **kwargs): super(PostForm, self).__init__(*args, **kwargs) self.fields['title'].widget.attrs.update({'class': 'input'}) self.fields['content'].widget.attrs.update({'class': 'textarea'}) class ImageForm(forms.ModelForm): image = forms.ImageField(label='Image') class Meta: model = Images … -
Is there a way to test Django project creation with pytest/Django test suite?
I created a Django plugin system which creates some boilerplate code. It can be used in any Django project (GDAPS), and provides a few management commands. What is the best way to test this whole suite? I mean, I can create bash scripts that setup fake Django projects which include my project, and then call all the management commands like makemigrations, migrate etc. to set it up fully, call my special commands (./manage.py initfrontend) and check if the results created the right files correctly. Now bash scripts are not my favourite testing suite, I'd keep with python and pytest if possible. Is there a way to test things like that? How can I start here - I can't wrap my head around this. I have already written plenty of unit tests for various features of the framework, but these tests are alike integration tests. Thanks for your help. -
