Adding Objects Updating Data via API

Adding Objects - Updating Data via API

So those test cases are going to cover our insertion of new records for products and for descriptions, so that completely covers all of our methods for the descriptions resource that we created.

So we only had index and we had store. But if you remember we still have an update method on the product, so if we actually want to create or update an existing product, we still want to write code for that.

So let’s go in and what we’ll do is we’ll just copy our test case for test product creation and let’s call it testProductUpdate`. And so here what we actually want to do is we want to create the initial record so we’ll change that from make to create.

We’ll say the name is equal to 'beets'. And then instead of the store, let’s try to pass this into, we’ll use a PUT method, and we’ll pass this into the API products. update and as another parameter here because we need to include the productsId.

Let’s use the productId that we’ve we’ve just generated and then, we need to change the product name to be something else. So here let’s do like 'feats'. And then we’ll do product toArray so now it’s going to say this is we’ve created a new product in the database its name was 'beats', then we’ve, after we’ve created it, we’ve changed the value of it to be 'feats' and then we are going to make a request to the update method with that productId and saying okay the new name actually needs to be 'feats'. And so, when we’re done, what we want to do is we want to make sure that we see in the database a product with the name 'feats'. Let’s try to run this. This is going to fail cause we haven’t actually implemented the method.

So if we go back to our ProductController what we can do is in our update method, we want to first make sure that the product exists. So we’ll do product, just like we did in the other method, findOrFail and we’ll pass in the ID that’s provided, and then if it exists we will update and we will provide the values that need to be updated. No I want to be explicit, sorry. So here we’ll say name and name is going to equal the new name that came in from the request.

    public function update(Request $request, $id)
    {
        $product = Product::findOrFail($id);

        $product->update([
          'name' => $request->input('name');
        ]);
    }

Cool? So let’s see if our tests pass now. And we’re green. Great. Got updates, we got inserts, we got indexing, we can see all of that. Great.
