Airlines | project imitates a basic airline reservation system | Application Framework library

I'm trying to include a logo when adding a new airline, but I don't know how can I pass input with file type to the controller with ajax. I tried to use FormData(). I did not get any error, but the file was not passed to the controller I have looked at some questions similar to my problem, but I can't find a solution.

I have a graph of Airports, Routes between them and Airlines that carry it. I created routes as separate nodes, rather than just a relationship, so that I can connect each with an Airline, and other nodes.

Each Route node has an IS_FROM relationship with the origin airport and an IS_TO relationship with the destination. It also has an IS_BY relationship with its airline:

I am trying to traverse this tree, n times, for routes between two airports. For example, if n = 3, I want to get all the routes, that will lead from LAX to LHR, with 3 or fewer connections.

So basically, my result would be a union of the following: No Connecting Airports:

I have a query as below. When i search using the query below, it fetches the products but it shows other products from other airlines even tho i have specified the airline id. When i take out the orWhere("code","LIKE","%{$request->search}%"), it works perfectly fine and it doesn't show the products of other airlines.

I know where the issue is but then i still need the search parameter to be either name or code. How do i fix this ?

I'm working on one of the tutorial exercises "Bootcamp, Day 1"

Specifically, the problem says

Filter this Flights path to only: Flights between Delta Airlines hubs (ATL, JFK, LGA, BOS, DTW, MSP, SLC, SEA, LAX)

I know in SQL I would do something like:

I understand the problem and showed all my work. I'm working through the modern dive data science book (https://moderndive.com/3-wrangling.html#joins book), and got stuck on (LC3.20) at the end of chapter 3.Using the nycflights13 package on R and dplyr, I'm supposed to generate a tibble that has only two columns, airline name and seat miles. Seat miles is just seats * miles. I understand the problem and I thought my code was going to output the correct result, however my seat miles are different for each airline carrier than in the solution. Can someone please help me to figure out why my code went wrong. Additionally, I do understand the books solution, I just don't know why my solution is wrong. I posted all my work.

I'm trying to answer a homework problem, and I'm not very good at R Studio. The problem involves the nycflights13 dataset. The question is, "Using the flights data, identify which airline carrier had the most flights in 2013? Which had the fewest number of flights? Do this using max() and min()."

So far I've used this:

table(nycflights13::flights$carrier)

It's helped me retrieve a frequency table of the carriers. I know United Airlines has the most and Skywest has the least. But how do I prove this using max() and min()? It has only returned the highest and lowest alphabetical values of the carriers. Thank you!

I'm trying to make my website responsive and for mobile and iPad it seems to work pretty well but for desktop I have a problem. I'm trying to figure out how to expand the two upper boxes (image and text). My website looks like this right now:

But the result should look like the picture to the left:

Here is my HTML for the two upper boxes:

I am trying to execute the Data Generator function provided my Microsoft to test streaming data to Event Hubs.

Unfortunately, I keep on getting the error

I am having some trouble with EnhancedSeatMapRQ, as the seats for certain airlines (e.g. AC, AA, etc.) do not return any BasePrice or Price node. When checked with Sabre software, some of these seats do have a cost charged upon booking.

My understanding is in these situations, the CommercialName value is supposed to help lookup the price. With that said, there is no reference in the response that indicates any price, for anything.

Here is one with a price node:
