spaghetti | Infinite scrolling for Rails

I am getting error message while trying to add a subquery of dataset before generating the plot in Shiny. I used sqldf to subset the dataset from a dynamic input on slider input in UI. Error message was listed below. Not sure what happen.

'Warning: Error in : near "[[input$namesn_chg]": syntax error [No stack trace available]'

Layout in app:

UI.R:

I have a database that stores information about dishes of a gastronomy and the customer orders.

I want to write a form that allow the user-admin to insert the data about a plate, with name, ingredients and allergens. The last two accepts multiple values.

I'm using a formGroup that contains (for now):

The object within an object contains variables such as "name", "amount", "amountType", and "cal". The strings on those variables should be transferred through loop as several row in the given HTML table. Each variable should be on its own cell.

I already made one row and made 4 cell for the name, amount, amount type, and calorie columns. Then, I tried to transfer the objects elements inside the cell using the index of the object.

On the function "createIngrList", it should take all the ingredient names, such as "Butter", "Beef", "Onion", etc., and turn it into buttons. So each button should have a text with the name of an ingredient written on it. As of now, there is just 4 buttons with "undefined" written on it. If possible, all the repeating ingredients such as "Onion" should not be made into button twice. Once is enough.

Is it possible to format a message sent by a telegram bot as a list?

I want to build a bot that presents the menu of a restaurant with about 20 options and sub-options (e.g., kind of meat) as a list:

I am still somewhat of a novice to React with much to learn. At the moment I am trying to make a page displaying lightsabers and hilts from Star Wars by clicking a button to show the ones you want. I am doing this by using State, which by the amount of states I currently have seems like the wrong way of doing it.

Here's how I'm doing it: I set a State and put an onClick event that sets the chosen hilt/color to true and the rest to false whilst also rendering information of said hilt/color. It looks like this:

My particle simulation is using up too much ram. What's concerning to me isn't the amount in and of itself, but the fact that it grows exponentially when I have reason to believe that it should not. I am using CUDA, which is the component I added most recently and thus what I suspect to be causing the issue. I have determined that it is not (only) a problem within the kernel, as the ram usage grows even when the kernel is not being run. I suspect it has to do with the way I am allocating memory, but I do not understand where I went wrong. I apologize for such a trifling question, I am new to CUDA (if that wasn't obvious). Here's the spaghetti in question, thank you for your time.

I am new to react and I am having some trouble mapping nested array of objects in my app as it comes as undefined.

This is my api response which is an array of recipes.
