I was making a simple to do app with mvc pattern and I saw an article which said you shouldn't pass the model values directly to the view, which made the project more complex than I thought (I am relatively new to programming and this is the first time I am trying out a design pattern).

But then later on I talked to someone who said that that is not true and you can send the model data directly to view, he didn't even use classes or some kind of grouping to separate the function he just put them in separate files.

I was wondering if there is a guideline that I couldn't find or we can do whatever we want as long as they are kind of separated. I would love an article or a guide to read up on as well.

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

I'm using React and Next.js with Firestore. On one page I get data from Firebase with useEffect only once the page is rendered. But since the get is kind of costly (lots of read), I want to persist the data fetched even when the user navigates to other pages and back to this page, so that I don't need to fetch again. How can I do that? Thanks!

So... I can sympy.integrate a normal distribution with mean and standard deviation:

I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)

I would like to prevent a turtle from visiting a patch it has visited before. I'm developing the code, but this error appears: error: "a patch cannot access a variable of a turtle without specifying which turtle".

I'm pretty sure it's another syntax error. But, I am not able to find this error. I tried to simplify the code to make it easier for you guys to help me. Any kind of help is welcome.

My code should print the number of all the words replaced from Z's to Y's, using a while loop.

In tkinter I have made a notepad and also added a scrollbar to this notepad. The problem is when I click on the scrollbar (not using any arrow keys nor mouse scroll wheel)

I have tried google but I'm not the best at finding the right websites.

Heres the code to the notepad

I wrote a discord bot. "o" is first letter of play. "atla" is skip. When I wrote -o MUSIC_NAME, music is adding queue and starting to play. And when I write again, just adding queue. Everything is okay still here. When I wrote -atla. It's also working perfectly. But when I allow to changing auto music itself, it's changing music automatically. But problem is here. The end of the last music not working else if (list.length === 0) block in endHandler function. How can I fix that? Thanks for your attention.
