Installation

The connector works in the context of Arrow application.

So first create your Arrow application.

In the terminal from the root of your app install the connector with:

appc install connector/appc.odata

Configuration

After the installation you will see conf/appc.odata.default.js config file.

It will contain template with all configuration parameters.

Some of them have default values but other must be configured appropriately.

For this connector you need to set the following configuration properties:

    connectors: {
      'appc.odata': {
        url: '<MANDATORY. THE CONNECTION URL TO YOUR ODATA SERVICE>',
        generateModelsFromSchema: 'MANDATORY WITH DEFAULT VALUE = TRUE. CREATES MODELS FROM THE METADATA',
        modelAutogen: '<MANDATORY WITH DEFAULT VALUE FALSE. WHETHER OR NOT TO GENERATE APIS FOR THE MODELS>'
      }
    }

Usage

Run your arrow application with:

appc run

Then open the admin ui pannel usually at http://localhost:8080/arrow to play with the available models and exposed endpoints.

Auto generated keys and user defined ones

The connector handles data sources with auto generated ids and user defined ones. If your service has auto generated ids you'll see the Key of every entity as 'id'. Otherwise you'll also have a dublicate of the id. For example if your Key is 'UserName' the dublicate will be visible as 'UserNameID' and will have the same value as 'id'.
You can create a new record by entering the value for the Key as the dublicate. For example if we enter data:

{
  'UserNameID': 'johndoe',
  'Age' : 30
}

and we have Key for the table 'UserName' this will create a record with 'UserName' johndoe and 'Age' 30.

Where clause

The connector supports queries. You can use the following:

{"Name": {"$eq": "Tom"}}

to get the record with 'Name' equal to 'Tom'.

Full list of all supported operators :

Operator	Meaning
$lt	less than
$lte	less than or equal
$gt	greater than
$gte	greater than or equal
$ne	not equal
$eq	equal
