Wherever I search, I find that to use a method without an object, THE ONLY WAY IS TO MAKE IT STATIC. However, in the following piece of code I show two examples of non static methods being called without an object FindIngredient and NumPizzas()((*) and (**)). It compiles and not even warnings are given. As you can see I am not using static anywhere

How come it is possible?

I need FindIngredient to return a const Ingredient & when searching by Ingredient.name. I need to used unordered_set. So I think I need 2 of them one to contain the objects and another one just to contain the string attributes name in order to search by string.

Is my approach ok or can I achieve it using only unordered_set ingredients?

Following with my approach what how do I return in FindIngredient function? I want to return the object in ingredients whose attribute name is the one found searching in ingredientsByName

i am just learning about this combo of Optional chain and Nullish coalescing. Here is the object

I would like to call a function inside a forEach loop to display datas but the problem is that I must do again a for loop inside the forEach loop to access other elements and so if I put the my call of the function inside the forEach loop, other elements are not called and if I put the function inside the for loop (that is inside the foreach loop) the elements are displayed twice. Could you please help me ? Here is my code :

The state values are passed in the searchYelp props as parameters in the handleSearch function. The values should be logged in the console with onClick. However, the argument passed into the term parameter is not logged into the console while the other two arguments (location, sortBy) are logged into the console.

I'm working on creating pizzeria site. I decided to create id as SPA with fixed navigation. To simplificy my code I created it in modules and now I have a big problem with them. How I can link module function to button in headers, because it throws an error. Here I posted my code to demonstate the error. To fix it I tried to move parts of the code and generate that error.

I've just made it to the end of chapter 18 (Getting Started with Django) of Eric Matthas' Python Crash Course. I have the below function, Pizza, in views.py which is raising the Attribute error noted below.

I am currently developing a Pizza Ordering/Tracking system for my local pizzeria. As you can see below, I have the GraphQL types and Mongoose models defined. In my pizza, I have an array of toppings which I set to reference the topping model. My question is, what would my mutation definition and the call to that mutation with the required arguments look like?

I want my Pizza document in Mongoose to containt the relevant ToppingIds so I can reference other fields of that topping such as the name and price. Hope that's clear. Maybe an array is not the best way to approach this??

If there is a more efficient way to have toppings within the pizza model, pls do share.

GraphQL Types:

For my school project I've been assigned to make a program for a pizzeria. One of the tasks is to make text file that handles statistics over the amount of pizzas ordered.

I have an array of 30 pizzas to choose from. When a pizza is chosen the index number of said pizza, and the amount of pizzas chosen, needs to be written to the text file.

My question is: How would one do this?

Im writing in Java :-).
