An example of DynamoDB about laravel-dynamodb

[baopham]

Change to us-east-1 for the region

[baopham]

Hello, thanks for reminding me to update the docs. Here are the steps:

1. Configure your dynamodb credentials in config/services.php
2. Create your model class as usual
3. Extend this class with BaoPham\DynamoDb\DynamoDbModel
4. Set your $fillable property
5. Use the Eloquent syntax as usual

hi, thanks for your reply
but I still have difficult to connect dynamodb

Do i correct below for the model class?
app/Product.php

app/Http/Controllers/ProductController.php

with('products', $products); } }

such as I have a "products" table

• id
• name

but here have some errors

[baopham]

what are the errors?

[qyqyqy03]

FatalErrorException in Product.php line 8:
Class 'App\BaoPham\DynamoDb\DynamoDbModel' not found

[baopham]

You have the namespace wrong, put \ in front of BaoPham

class Product extends \BaoPham\DynamoDb\DynamoDbModel

If you use an IDE (PhpStorm), it'd help with error like this.

[qyqyqy03]

Thank you, it have good changing, but have the below error

DynamoDbException in WrappedHttpHandler.php line 192:
Error executing "Scan" on "https://dynamodb.us_east_1.amazonaws.com"; AWS HTTP error: cURL error 6: Could not resolve host: dynamodb.us_east_1.amazonaws.com (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

[baopham]

Please check your services.php again and see if you have put all the correct info. Good way to check also is to use artisan tink and call config('services.dynamodb')

[qyqyqy03]

services.php

    'dynamodb' => [
        'key' => env('DYNAMODB_KEY'),
        'secret' => env('DYNAMODB_SECRET'),
        'region' => env('DYNAMODB_REGION'),
        'local_endpoint' => env('DYNAMODB_LOCAL_ENDPOINT'), // see http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Tools.DynamoDBLocal.html
        'local' => env('DYNAMODB_LOCAL'), // true or false? should use dynamodb_local or not?
    ],

and i added the code in .env

DYNAMODB_KEY=XXX...
DYNAMODB_SECRET=XXX...
DYNAMODB_REGION=US_EAST_1

and the checking result
is
=> [
"key" => "XXX...",
"secret" => "XXX...",

 "region" => "US_EAST_1",
 "local_endpoint" => null,
 "local" => null,

]

[qyqyqy03]

error is the same
... "https://dynamodb.us-east-1.amazonaws.com" ...
only us_east_1 to us-east-1 changed

[baopham]

are you certain that it is the correct region?

[qyqyqy03]

yes, i am using "US East (N. Virginia)" which displayed in the top-right corner on aws console
and it works with the no framework php:
'region' => Aws\Common\Enum\Region::US_EAST_1,

[qyqyqy03]

Or is that is a feasible way to give me a template repository which just let me to fill in the KEY and SECRET and table name? Then i can connect with dynamodb and display the items on my table.

[baopham]

It seems more like a network issue actually.

Why don't you put up a quick repo of what you have so far and I can take a look.

[qyqyqy03]

It is a good idea!

The project I use "products" as my testing
Thanks!

[baopham]

I will take a look in the weekend.

[qyqyqy03]

Thank you!

[baopham]

I created a table products under region us-east-1 and it's working fine for me. Check your network if somehow it is blocked.

[qyqyqy03]

hi
I just added my key and secret in .env
then have a table called "products" like this

https://drive.google.com/file/d/0B7a_eGs6V1TobVdtMFZjNnl0XzQ/view?usp=sharing

with itemid and itemAddress attribute

However, when I go to http://localhost:8000/product
I still got the error of

"Error executing "Scan" on "https://dynamodb.us-east-1.amazonaws.com"; AWS HTTP error: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)"

[baopham]

That sounds more like a different problem. Google will help. For example, http://stackoverflow.com/questions/28858351/php-ssl-certificate-error-unable-to-get-local-issuer-certificate

By the way,
Is itemid your primary key? if so, please set it in your Product class:

protected $primaryKey = 'itemid';

by default your primary key is id

[qyqyqy03]

am i right?
https://drive.google.com/open?id=0B7a_eGs6V1ToUjhUZEdkZEdnTzg

and this in Product.php

[baopham]

Yes, but you should use string for primary key. Dynamodb does not support incrementing ID. You have to set the ID yourself. But this is a separate thing I wanted to point out. You should google for the error that you're getting

[qyqyqy03]

thanks!
why you are working fine but I cant for the same repo with same changes?

[baopham]

My local server has ssl cert setup correctly?

[qyqyqy03]

I finally got the item data but in an error page
but it is a great step for me
Thank you so much!

[baopham]

great

hi
I have a problem with upload photo with S3

In the ..blade.php
{!!Form::file('image')!!}

In the Controller

public function store(Request $request)
    {
..........
$imageFileName = "123.png";
$s3 = \Storage::disk('s3');
        $filePath = '/mybucket/' . $imageFileName;
        $s3->put($filePath, file_get_contents($request->file('image')), 'public');
............
}

Why I have an error on

file_get_contents(): Filename cannot be empty

[baopham]

This has nothing to do with this library. Please use Stackoverflow for this.
