In my HomeController, I am having trouble with my create function accessing the database. After submitting the form in my browser, this is the error that shows:

Error Given

MySqlException: Cannot add or update a child row: a foreign key constraint fails (petshelterdb.pets, CONSTRAINT FK_Pets_Owners_OwnerId FOREIGN KEY (OwnerId) REFERENCES owners (OwnerId) ON DELETE CASCADE) MySqlConnector.Core.ResultSet.ReadResultSetHeaderAsync(IOBehavior ioBehavior) in ResultSet.cs, line 49

I am not using a login/registration. The idea is that I have a "bulletin board" that shows pets that can be adopted and owners that can adopt. A new pet or owner can be added to the board. If I select the owner's name, I can have that owner "adopt" a pet on the board. I designated in the HomeController code which line is the issue.

Since I'm not working with a UserId, I'm not sure how to go about this.

I am using an array of links to paginate because I want them in a specific order. This all works fine, if I navigate to any of the features pages I can paginate through them; but if I refresh a page the Next href defaults to [0] or 'features/safety-training' and Prev ends up being undefined. I am assuming this is something to do with how useEffect works but I am not sure how to fix it.

I want to extract all data of security bulletin table from html https://helpx.adobe.com/security/products/dreamweaver/apsb21-13.html. Based on my code, I only can extract the data in the table one by one. The code cannot extract the overall data from the table.

This is my code

I'm trying to pass a struct as a generic type (seen in Model). I tried using AnyView to represent my structs, but the complier errors out on build with:

I'm using the GenerateFlowFile processor in Apache Nifi - When I activate it, I want the processor to create exactly 1 Flowfile.

Right now I use the REST API via Python to change the state to RUNNING, wait 0.5 seconds and change the state to STOPPED. This results in 1 FlowFile being added to the queue to the next processor.

I tested a bit and waiting for 1.5 seconds gives me 2 FlowFiles, 2.5 seconds gives me 3 FlowFiles - I'm guessing the processor generates one Flowfile each second it is running.

How can I ensure that exactly 1 Flowfile is being generated? The above method obviously is dependent on the network connection and roundtrip times. Worst case: the connection drops while I wait and I cannot stop the processor anymore and x Flowfiles are being generated.

My current configs are:

I'm using BulletinBoard (BLTNBoard) to create dialogs in my iOS app. There's an option to embed image inside it. I would like to extend it's functionality and allow user to manipulate this image using tap gesture. But eventually when I assign a gesture to it's imageView using addGestureRecognizer nothing happens.

Here's how I initiliaze bulletin and add gesture to the image:

After reading a large json file and capturing only the 'text' column, I would like to add a column to dataframe and set all rows to a specific value:

I'm solving a basic C problem on a site called UVa Online Judge, and I encounter an error which seems to related to compiler options.

I'm creating a simple to do app. I store my cards/bulletins in the BulletinsList.js and single bulletin/card in a Bulletin.js.

I'm trying to change "Hello World" (using input in Bulletin.js, by clicking on title and switching it to input) title in first bulletin but nothing works so basically I can't update a property of object stored in array. I'm passing an id of object but it doesn't work as well. Could anyone give me a answer how can I do this?
