#Help ASTRO DB CRUD
onyx smeltBOT
To delete a row with Astro DB, you can use the db.delete() function. Here's an example of how to delete a row from a Comment table by the id param:
import type { APIRoute } from "astro";
import { db, Comment, eq } from 'astro:db';
export const DELETE: APIRoute = async (ctx) => {
await db.delete(Comment).where(eq(Comment.id, ctx.params.id ));
return new Response(null, { status: 204 });
}
In this example, eq is a function used to compare the id of the Comment with the id passed in the context (ctx.params.id). If they match, the corresponding row is deleted from the Comment table.
Please note that you should use the eq function for the where clause. Using a raw object is not supported as per this Github issue (https://github.com/withastro/astro/issues/10489).
For more information, you can refer to the Astro DB guide (https://docs.astro.build/en/guides/astro-db/).

@onyx smelt How to display row in my page and how to delete
onyx smeltBOT
Let me check the knowledge base for you. One moment! :books:
To display rows from your database in an Astro page, you can use the db.select() function. Here's an example of how to select all rows from a Comment table and display them:
---import { db, Comment } from 'astro:db';
const comments = await db.select().from(Comment);---
<h2>Comments</h2>
{ comments.map(({ author, body }) => ( <article> <p>Author: {author}</p> <p>{body}</p> </article> ))}
In this example, db.select().from(Comment) selects all rows from the Comment table. The result is stored in the comments variable, which is then used to display each comment on the page.
To delete a row, you can use the db.delete() function. Here's an example of how to delete a row from a Comment table by the id param:
import type { APIRoute } from "astro";
import { db, Comment, eq } from 'astro:db';
export const DELETE: APIRoute = async (ctx) => {
await db.delete(Comment).where(eq(Comment.id, ctx.params.id ));
return new Response(null, { status: 204 });
}
In this example, eq is a function used to compare the id of the Comment with the id passed in the context (ctx.params.id). If they match, the corresponding row is deleted from the Comment table.

@onyx smelt Show me the code with a button to delete a row
onyx smeltBOT
Let me check the knowledge base for you. One moment! :books:
To delete a row with a button click, you can create a button in your Astro page and add an event listener to it. When the button is clicked, it sends a DELETE request to the API endpoint responsible for deleting the row. Here's an example:
<Layout title="Edit {friend.name}">
<h1>Edit {friend.name}</h1>
<p>Here you can edit or delete your friend's data.</p>
<form method="post" action={`/api/friends/${id}`}>
<!-- form fields here -->
<button type="submit">Edit friend</button>
</form>
<button type="button" id="delete-document">Delete</button>
</Layout>
<script>
const deleteButton = document.getElementById("delete-document");
const url = document.querySelector("form")?.getAttribute("action");
deleteButton.addEventListener("click", async () => {
const response = await fetch(url, { method: "DELETE" });
if (response.redirected) {
window.location.assign(response.url);
}
});
</script>
In this example, the deleteButton is the button with the id delete-document. When this button is clicked, it sends a DELETE request to the URL specified in the form's action attribute. If the response is redirected, it navigates to the redirected URL.
Please note that the DELETE request should be handled in your server-side code. In the case of Astro, you would handle this in your API route as shown in the previous examples.
For more information, you can refer to the Astro guide on Firebase & Astro (https://docs.astro.build/en/guides/backend/google-firebase#edit-or-delete-a-record).

@onyx smelt Where is the endpoint ?
onyx smeltBOT
Let me check the knowledge base for you. One moment! :books:
The endpoint is defined in your server-side code. In Astro, you typically define API routes in the src/pages/api/ directory. Each file in this directory corresponds to an API endpoint.
For example, if you have a file src/pages/api/comments/[id].ts, it defines an API endpoint at /api/comments/:id. Here's an example of how you might define a DELETE endpoint in this file:
import type { APIRoute } from "astro";
import { db, Comment, eq } from 'astro:db';
export const DELETE: APIRoute = async (ctx) => {
await db.delete(Comment).where(eq(Comment.id, ctx.params.id ));
return new Response(null, { status: 204 });
}
In this example, the DELETE endpoint deletes a row from the Comment table where the id matches ctx.params.id.
For more information, you can refer to the Astro guide on API routes (https://docs.astro.build/en/guides/astro-db#insert).

@onyx smelt How to add a button "delete"
onyx smeltBOT
Let me check the knowledge base for you. One moment! :books:
To add a "Delete" button in an Astro component, you can simply add a button element with the type "button". Here's an example:
<button type="button" id="delete-button">Delete</button>
In this example, the button has an id of "delete-button", which you can use to select the button and add event listeners to it.
If you want this button to delete a row from your database when clicked, you can add a click event listener to it that sends a DELETE request to your API endpoint. Here's an example:
<button type="button" id="delete-button">Delete</button>
<script></script>
In this example, when the "Delete" button is clicked, it sends a DELETE request to /api/your-endpoint. You should replace /api/your-endpoint with the actual endpoint that handles the deletion of the row.
