QUESTION
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) .
- GCP Service Principle Persmissions:
@appspot.gserviceaccount.com
hasCloud SQL Client
for theApp Engine default service account
so this should apply to all App Engine Services. - 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. - The code works locally (Docker) while linking the GCP Postgres database, but only with TCP routing, not a Unix Socket SQL proxy:

- Go to my App engine default service principal and give it the following roles (as described here)
- Cloud SQL Client

- Change socketPath key to 'host' in the following default connection settings:
QUESTION
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}
?

QUESTION
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
...ANSWER
Answered 2021-Nov-14 at 01:30That error states is that you are trying to remove from html something, that isn't actually html element.
For example:
QUESTION
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:
...ANSWER
Answered 2021-Nov-12 at 00:58There is a few issues with your code, but the main reason you don't see any changes in the DOM is that you try to find an element by id "main", but no such element is defined.
So step one is putting an id on the element containing your books:
Another issue is that you change the DOM in different ways on many places in your javascript code which makes it harder to figure out what's going on. You could change the addBookToLibrary
to actually add elements to the DOM aswell. To ensure consistency with the initial books you create in the foor loop, I have changed the addBookToLibrary to handle the entire creation and removed the for loop.
QUESTION
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:
...ANSWER
Answered 2021-Oct-05 at 00:00In order to match the brackets in your original query you will need to nest functions into your kenx query. Either of these should work depending whether you want to use Bookshelf or just knex.
