Django multi-app static files - developing locally and pushing to Elastic Beanstalk server
I have a django project with multiple apps inside it as so: /UserProject /Static /UserApp /UserApp/Static I have my global styling held within the /static/ folder, then individual UserApp styling held within the UserApp static folder. Then, within my settings.py I have: STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) This is great for local development - I can run the development server and the site updates as I update the stylesheets within either the root /static or the UserApp /static. However, when I push to my elastic beanstalk instance (depending on my configuration) - I get either (a) only the root /static files loading, (b) no static files loading or (c) an error on deployment You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path. I have tried using the following in my .ebextensions folder container_commands: 03_collectstatic: command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput" But this gives me the staticfiles app error. What is the correct setup in my settings.py to allow local development, and then also allow pushing to the EB instance? -

add to favourite list in django
I have added the add to favorites list feature for each product on the product page of my website, and the user can add any product to their favorites list. But if the user already adds this product to the favorites list, I want the word remove to be displayed instead of the word add, so that if he wants, he can remove that product from his favorite list. But the following error occurs: AttributeError: 'QuerySet' object has no attribute 'favourite' # model class Product(models.Model): title = models.CharField(max_length=200) favourite = models.ManyToManyField(User, related_name='user_favourite') # view def product(request): products = Product.objects.all() is_favourite = False if products.favourite.filter(id=request.user.id).exists(): is_favourite = True context = {'products': products, 'is_favourite': is_favourite} #template {% if is_favourite %} <a href="{% url 'home:favourite' product.id %}"> remove </a> {% else %} <a href="{% url 'home:favourite' product.id %}"> add </a> {% endif %} -

403 Forbidden request when making an axios call with React (Django backend)
I am trying to authenticate my session on a web application using ReactJS. My backend is setup on Django.

Django foreign key: auto-lookup related object when the update record has the key value
I have legacy code which had no foreign keys defined in the schema. The raw data for the row includes the key value of the parent, naturally. My first porting attempt to postgresql just updated the field with the raw value: I did not add foreign keys to Django's models. Now I am trying to add foreign keys to make the schema more informative. When I add a foreign key, django's update requires me to provide an instance of the parent object: I can no longer update by simply providing the key value. But this is onerous because now I need to include in my code knowledge of all the relations to go and fetch related objects, and have specific update calls per model. This seems crazy to me, at least starting from where I am, so I feel like I am really missing something. Currently, the update code just pushes rows in blissful ignorance. The update code is generic for tables, which is easy when there are no relations. Django's model data means that I can find the related object dynamically for any given model, and doing this means I can still keep very abstracted table update logic. So … -
Javascript Error - Uncaught ReferenceError: load_mailbox is not defined at HTMLDocument

How to get html form field data in JSON and insert into database with Django?
I have created one project where User Registration functionality is there. Once user fill the form, I'll be getting data in Django using POST and insert into Database. Now I don't want to get data into my code directly from the form. My requirement is: 1. Once User fill the form and submit, then JSON data should be created so that I can give that API to the frontend. 2. I would take that JSON data using API and insert that record into my MySQL database dynamically for different users.

AJAX way of handling filters in a Django based ecommerce application is not working upon copy pasting the url in new tab
So I ran into this problem two days back and still haven't got a proper solution. I would highly Appreciate any help in here. Let me explain the scenario first, so the idea is I have one django based ecommerce site and I want to render the product showcase page through ajax call (without reloading) and same time also update the url as the selected filters for example (http://vps.vanijyam.com:8000/customerlist?category=category_1).

How to receive notifications from PostgreSQL table in Python
I'm using psycopg2 for Postgres in python and want notifications and row data when the DateTime column data matched with the current time from the Postgres table. I can do this with a scheduler that is run on x seconds interval and get the rows that are matched with the current time, but it is the worst solution. So, I have to get Listen/Notify in Postgres which is notified when some new changes occurred in the table. Is it possible to get this scenario from Listen/Notify? An alternative solution will be appreciated. -

However, I keep getting undefined, I can console log the data and see what I am trying to target with my index numbers but I am having no luck. I also tried using JSON.parse() but this just threw an error. For visualisation here is what the console.log prints:https://ibb.co/9y8CBw9 Here's what I've got for my Javascript: document.querySelector('#userLists').addEventListener('click', function(event) { if (event.target.dataset.name) { var listname = event.target.dataset.name console.log(listname); getTableData() } }) const getTableData = function(){ $.ajax({ type: 'GET', url: '/api/uservenue/', data: {}, success: function (data) { data.forEach(item => { console.log(item.venue) }) fillTable(data) } }); }; function fillTable(data) { console.log(data) const table = document.getElementById("dashboardTableBody"); let row = table.insertRow(); let name = row.insertCell(0); name.innerHTML = data[0][1]; } Here is my serializers from DRF: class mapCafesSerializer(serializers.ModelSerializer): class Meta: model = mapCafes fields = ['id', 'cafe_name', 'cafe_address', 'description'] class UserVenueSerializer(serializers.ModelSerializer): venue = mapCafesSerializer() class Meta: model = UserVenue fields = ['id', 'list', 'venue'] And these are the pertinent models: class UserVenue(models.Model): venue = models.ForeignKey(mapCafes, on_delete=models.PROTECT) list = models.ForeignKey(UserList, on_delete=models.PROTECT) class mapCafes(models.Model): id = models.BigAutoField(primary_key=True) cafe_name = models.CharField(max_length=200) cafe_address = models.CharField(max_length=200) cafe_long = models.FloatField() cafe_lat = models.FloatField() geolocation … -
