Dockerized Django Application Deployed to AWS Elastic Beanstalk Flushes Database Everytime I Rebuild My Environment
I have deployed a django application using docker to AWS Elastic Beanstalk that is connected to an AWS RDS postgresql database. Everytime I update my code and rebuild my docker image, the database is always wiped clean. I am using github actions to deploy my application everytime I push my code. After searching for similar issues, most people suggest that there might be a flush command in one of the deployment scripts. That is not the case in my deployment scripts because I never explicitly flush the database.

JSON generated by json.dumps() is NOT valid according to RFC 4627
My Django management command generates some JSON. It creates a couple of Python dictionaries, puts them into another dictionary, and uses json.dumps() to convert to JSON. It then tries to save it to JSONField in database using a Django Model. The JSON is not saving due to it not being valid. I checked the JSON with many validators. They all said the JSON is invalid due to: Error: Parse error on line 1: { 'nodes': [{ 'name' --^ Expecting 'STRING', '}', got 'undefined' Eventually I found a validator that said the JSON is Javascript valid but not RFC4627 valid: I can't post the JSON here due to it being sensitive. Is there any reason json.dumps() would generate invalid JSON ? -
DRF serializer parsing comma-delimited string into a list field
Is there a way of modifying how DRF serializers parse incoming request payload? I'm trying to let clients send a comma-delimited list as query parameter but receive it inside the serializer as a list instead but DRF keeps complaining. Right now I'm manually intercepting the request in the view and doing the parsing that field manually before passing it to the serializer which doesn't seem elegant to me. What I'm doing right now class ExampleSerializer(...): list_field = serialzers.ListField(child=serializers.Integerfield(...)) # more fields def view(request): payload = request.GET payload["list_field"] = str(payload.get("list_field", "")).split(",") serializer = ExampleSerializer(data=payload) What I'd prefer (using same serializer as above) def view(request): serializer = ExampleSerializer(data=request.GET) -

I have a Ingredient model and a Shopping model for a shopping list and I would like to group ingredients by their category in the shopping list view.

get more than two foreign keys from another django table and perform calculations on them
In the Django app, I have created two tables. Product Invoice I have one table called Product which contains product name and product price columns are given.

django html: copy form input data and display in another page
I am trying to develop a delivery service web where users can input pickup and delivery address in the form and get the price online. if the price is fine, the user can click "place order" button which will navigate into another new page for user to fill in additional information, and importantly the previously input piackup and delivery addresses and the price will need to automatically shown somewhere in the new page. I am new to django and html, and I have tried to created a simpler page serving the same purpose. Now I could do the first part of form filling, and the backend calculate based on the user input and return the calculation result (e.g. price). Now, I am wondering how to do the "navigation to another new page which will display the two input values and calculation result" Main html: <html> <body> <form method="POST" hx-post="{% url 'blog:post_list' %}" hx-target="#num_1" hx-target="#num_2" hx-target="#result"> {% csrf_token %} <div> <label>num_1:</label> <input type="text" name="num_1" value="" placeholder="Enter value" /> </div> <div> <label>num_2:</label> <input type="text" name="num_2" value="" placeholder="Enter value" /> </div> <br /> <div id="num_1">{{ num_1 }}</div> <br /> <div id="num_2">{{ num_2 }}</div> <br /> <div id="result">{{ result }}</div> <br> <button type="submit">Submit</button> </form> … -

Multiple FeaturedPost on HomePage Using Wagtail
I haven't seen any question like this on the site. So hopefully this question will be useful for others in the future. I have a PostPage, EditorialPage, and DocumentPage.

However, in the HomePage/Models, I only was able to get it to work with PostPage. I'm not too keen with query/querysets, but I feel it has something to do with that.
