I have JSON file 'json_HW.json' in which I have this format JSON:

i'm trying to make query for user in Django, but still every user can see all data from data base. I've tried with filters, q objects, but none of these helped me.

Here is my model:

I am working on a small project to improve my OOP skills in C++ - the project is just a simple collection of books, sort of a home library, where the books can be stored in virtual shelves, grouped into bigger bookstands with respective names etc, with each book additionally having its own ID, being a positive integer. I was trying to create a user-defined class destructor and I wanted to move the destructor's implementation to a source file, following the rule to move longer than one-line-long implementations to a .cpp file from .hpp file to help building up a habit of producing a better optimized and faster code (of course in this example it will not help, but I just want to find a solution to the encountered problem, not to struggle in the future).

However, when trying to compile my code, I get the following error:

I am following the tutorial for Strapi on CGP App Engine (nodejs- standard env) and unable to get the app to start because the connection is being refused Error: connect ECONNREFUSED 127.0.0.1:5432 by the GCP Postgres instance (Public IP) .

1. GCP Service Principle Persmissions: @appspot.gserviceaccount.com has Cloud SQL Client for the App Engine default service account so this should apply to all App Engine Services.
2. I have other App Engine Services (python) connecting successfully to other Postgres Databases. This tells me I have the correct permissions, Cloud SQL Admin API enabled, and the correct username/password.
3. The code works locally (Docker) while linking the GCP Postgres database, but only with TCP routing, not a Unix Socket SQL proxy:

In the Google Getting started with Node.js tutorial they perform the following operation

data = {...data};

in the code for sending data to Firestore.

You can see it on their Github, line 63.

As far as I can tell this doesn't do anything.

Is there a good reason for doing this?

Is it potentially future proofing, so that if you added your own data you'd be less likely to do something like data = {data, moreData}?

I have a library web application I am working on. There is a form that allows the user to add a book to the library and enter information about the book. Once the book is submitted a html card is generated on the webpage with a checkbox and a remove button. The remove button works on any card, however if I then use it to try to remove a second book i receive the error

I am currently working on an exercise in HTML/CSS/JS. The premise is a library website. The idea is that I have a collapsable form that when deployed allows the user to enter the title of the book, the author, and page numbers. When submit is clicked it takes the user input and generates a html card on the webpage. This title card will display the user input information along with a slider to denote if it was read or not.

I have a few test cards generated in my code that creates the cards as intended, however when utilizing the html form i can not seem to get additional cards to create. I ran some tests to the console to ensure that the form is in fact capturing the user input and assigning it.

If anyone could point me in the right direction that would be amazing. I have been messing with this issue for almost 2 weeks with no luck. I have a feeling that my "wires" are not connected right in the javascript. Thank you in advance.

Javascript:

I'm trying to convert a simple raw SQL to use Bookshelf/Knex in JavaScript:

Original SQL: select * from o where o.id = 1 or o.id = 2 and (o.is_a = true or o.is_b = true) and o.status = 'good';

I've tried to rewrite it in multiple ways using .orWhere .andWhere but cannot get the same result that I get from SQL. What am I doing wrong?

Some of the attempts:

Hey how can I change this code to enter each page and get the info from this url I want ( the book name and the url of the book )

i wrote ( with google help ) this code but i want to get all the books from all the pages ( 50 pages )
