groceries | A web-based grocery-management app | Mobile Application library

I am trying to make a to do list using React Native. How can I delete multiple items in FlatList all the items that has the state of completed: true with a TouchableOpacity(acting like a button). I do not know what methods I should put in function deleteCompleteTodo()

I have a spring project which has the following interface.

I am working on Colt Steele Web Dev Bootcamp exercises and running into a issue I don't understand. When I hit "quit" or "q", the application should quit. However, you have to enter "quit" or "q" twice in order for the application to result to false. User should only have to type quit once. updated codepen

I Implemented a small ERP system for our kitchen. The system is used to track our groceries, so it contains the goods (referred as food) with its name and UPC code. Over the time the names and upcs started to overlap and creating a data problem. In a first attempt we started to add the manufacturer into the name of the food leafing us with data which looks like this.

The names are German, sorry for that. The first part of the name is the manufacturer and the second part is the name of the food. I now introduced a new table called 'Manufacturer' which holds an Id and a Name. The table for the foods was extended by the ManufacturerId field. I want to have the following tables

I tried warping my head around a SQL statement which will solve this for me but I couldn't find any solution.

• Not all entries in the food table already have a manufactuerer assigened. So the query has to filter for item which contain the a ';' in the name. Like

I have a simple "to-do-list" that I am trying to create that will display a to-do (an object with 4 properties) in a list (an array of objects). I am initializing the list with two to-dos already, and I want the ability to remove a to-do from the list with a button click (the button is held inside the "to-do" component).

Here is the component that creates a single to-do and includes the button for removing it from the list.

so my goal is to have the apple pay button show up on devices that support apple pay and be hidden on devices that do not support it.

Currently I have a vc with two buttons, one is an Apple Pay button and one is a button that segues to a normal checkout. I use logic to determine the right buttons to show, if the device supports Apple Pay it'll show both, if not, it'll show the normal checkout button.

Here is an example of the simulator, a device that supports Apple Pay:

This is what it should look like for a device that supports Apple Pay. Here is the logic I use to determine what buttons to show:

I'm learning REST API with Python flask and JavaScript.

I've created the API successfully but whenever I try calling it with Ajax or JavaScript it fails but on the flask server it shows the 200 response.

My flask code:

I'm trying to crawl a website and Invoke-WebRequest is not displaying the a tag. Please see the following code:

I'm learning flutter and I'd like to make a simple todo app.

In the app you can create different "lists" (for example "Homework", "groceries"...) and each list consists of list of tasks, so I have to classes:

1. Task (to store a single task)

• String task
• bool completed

1. TaskList (to store a list, made up of tasks)

• String listname
• List tasks (consisting of Tasks)

I used a List made up of TaskLists with some data when I was testing it, but now I want to store the data to the device and I came across Hive, which is based on the idea of "boxes", but I'm not sure how I should approach this.

Should I create a new box for every new list (and then delete it, when the user deletes the list) or somehow store all the data in a single box?
