ASP.NET Core Web API with .NET 8, released in 2024, allows creating 1-to-many relationships easily through POST requests.

When creating comments for a stock, it’s like being the parent of a lively bunch of kids. The stock ID is the key to tying everything together, like a family tree. And just like a parent, you can have as many comments as you want – the more, the merrier! It’s all about forming those special relationships. So, hop into the code and let’s get creating! 🚀📈

Introduction 🌐

In our previous discussions, we were able to successfully retrieve comments from the database and establish the parent-child relationship between stocks and comments. Now, the focus is on creating comments and ensuring that they are automatically associated with the relevant stock. Let’s delve into the process.

Understanding Comment Creation 📝

When creating a comment, it is crucial to establish a connection with the parent stock. This requires passing the stock ID, as it serves as the linking attribute. The comment model includes the stock ID as a foreign key, facilitating the establishment of the parent-child relationship.

Implementing HTTP POST 🚀

To initiate the comment creation process, we begin by focusing on the HTTP POST method. We need to ensure that the parent stock ID is included, as a comment must be attached to a stock. This allows for the seamless association between the stock and the comment.

Stock Existence Verification ✅

We implement a method to check the existence of the parent stock, as it is a common scenario. This method abstracts away the code by checking if the stock exists, ensuring a smooth and efficient workflow.

| Stock ID | Stock Exists? |
|----------|---------------|
|   123    |    true       |
|   456    |    true       |

Mapping and Creation Process 🗺️

Once the stock existence is verified, we proceed to map the data from the create comment DTO to a regular comment. This involves implementing a mapper and mapping the required attributes to form the comment model.

Asynchronous Comment Creation 🔗

With the comment model prepared, we create a synchronous method within the comment repository to add the comment to the database. Upon adding the comment, we save the changes and return the newly created comment in the desired format.

| Comment ID | Stock ID | Content     |
|------------|----------|-------------|
|   789      |   123    |   Sample    |
|   1011     |   456    |   Example   |

Conclusion 🎉

The process of creating comments in the ASP.NET Core Web API involves a structured approach, ensuring the seamless association between stocks and comments. By verifying stock existence and mapping the appropriate data, the creation of comments is streamlined and efficient.

Key Takeaways:

• Establishing a parent-child relationship is crucial in comment creation
• Verification of stock existence is essential for seamless workflow
• Mapping and creating comments involves a structured and efficient process
