rides | The Peloton CLI | iOS library

I am trying to write a hierarchical configuration structure such that config files in the inner directories inherit from the config files in the outer directories. For example, in the following scenario

I'm using mysql and I have 4 tables involved in a query.

The relevant fields are the idRide from table ride, idDriver from table driver, idOwner from table owner and idDependant from dependant.

Driver is a supertable where both owners and dependants are drivers, in the table ride, you get idDriver and you can check on the tables owners and dependants to see which driver they correspond to. Each dependant also has as a foreign key the id of the owner they depend on.

How do I count the rides of owners and dependants and then I show only the owners who have more rides than their dependants?

I tried the following query but it does not work:

I'm calling an API but I've been trying to parse this JSON response correctly but I haven't been able to resolve this issue. I call the API, and want to display the data with a FutureBuilder and Provider, but I get that error Type 'List' is not a subtype of type 'FutureOr>' and I'm not sure what am I doing wrong. The code is below:

API Call:

I'm trying to pass the data to another screen using Provider, but it seems I'm always passing on the same data unless I sort the List and then pass the different data (meaning I'm probably switching the index by sorting the list so that is why it's passing different data now). In short, I call the API, populate the list, setting up the provider too for the next page, and on click I list out the the information from the previous screen, but the problem is I display the same item always unless I sort the list. Here is the code:

Calling the API and displaying the list:

Snippet of my code:

When I open the tab, for a second, there is this error. Then it goes away, how do I solve this? I'm assuming it takes time to generate the length value?

The goal is to find all car rides that are pricier than train rides that take place either in the same state or outside the country (aka 'Non-UnitedStates')

This is the only way I could get it to work. I feel like it's inefficient. I wanted to do something like

However, this leads to the table outputting all modes of transportation. Any pointers to fix? Additionally, the question feels unclear. I don't know if "taken on a train in the same state or outside the country" means just the train is outside the country or the car ride can be too.

I want to scrape data from a webpage with a dynamic table. The table contains information on train rides.

This is the website: https://www.laerm-monitoring.de/zug/?mp=3/

I tried to request the data with a simple mounted request session, but I only got basic HTML data without the data from the table.

I've successfully created my first web application using node js, ejs and mongodb.

I want to hide my login/sign up links when user logs in and want to display logout button in my header file.

Anybody got a solution? I've already tried Expressjs how to show / hide a div in case user its logged But for some reason, the user variable in ejs file is initialising to null, so only one case is exectuting

Here is my header.ejs file:
