Use Servoy Developer to easily connect to Square data and build web apps with connectivity to live Square data.
Servoy is a rapid application development and deployment platform. When paired with the CData JDBC Driver for Square, users can build Square-connected apps that work with live Square data. This article describes how to connect to Square from Servoy and build a simple web app to display and search Square data.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Square data. When you issue complex SQL queries to Square, the driver pushes supported SQL operations, like filters and aggregations, directly to Square and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying lets you work with Square data using native data types.
Connect to Square in Servoy Developer
To build Square-connected apps, you need to first create a data provider in Servoy Developer using the CData JDBC Driver for Square.
- Install the JDBC Driver.
- Copy the JDBC Driver JAR file. (cdata.jdbc.square.jar) to the /application_server/drivers/ directory in the installation directory for Servoy.
- Open Servoy Developer.
- In the Solution Explorer, right-click Database Server (under Resources) and choose "Connect to existing database" -> "empty."
- Name the server.
- Click to show the advanced server settings.
Set the URL, for example: jdbc:square:OAuthClientId=MyAppId;OAuthClientSecret=MyAppSecret;CallbackURL=http://localhost:33333;LocationId=MyDefaultLocation;InitiateOAuth=GETANDREFRESH
Built-In Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Square JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.square.jar
Fill in the connection properties and copy the connection string to the clipboard.
Square uses the OAuth authentication standard. To authenticate using OAuth, you will need to register an app with Square to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.
Additionally, you must specify the LocationId. You can retrieve the Ids for your Locations by querying the Locations table. Alternatively, you can set the LocationId in the search criteria of your query.
- Select the Driver class you just copied, for example, cdata.jdbc.square.SquareDriver
Build a Square-Connected Web App
Once you have configured the connection to Square in the Servoy Developer resources, you are ready to build apps with access to live Square data.
Create a New Solution
- In the Server Explorer, right-click "All solutions" and select "Create new solution."
- Name the solution.
- Select the checkbox to include the "search" module.
- Click "Finish."
Create a New Form
Right-click "Forms" and select "Create new form."
- Name the form.
- Select a Datasource.
- Set the type (e.g., Simple) and click "Finish."
Add a Data Grid to the Form
- Drag a Data Grid component (from Servoy NG-Grids) onto the form.
Drag a column component onto the Data Grid and set the "dataprovider" property for each column component to a column from the Square "table" (e.g., Reason from the Refunds table).
Continue adding columns as desired.
Add Searching to the App
Note that the "svySearch" extension is required to add search functionality (included by default when you create a new solution). If you did not add the extension when you created the solution or you are modifying an existing solution, you can add the search module by right-clicking Modules (in the solution) and selecting "Add Module." Select "svySearch" and click "OK."
- Drag a Text Field component onto the Form.
- Right-click the Form and select "Open in Script Editor."
- Create a new variable (JavaScript) to hold the search value:
var searchText = '';
- Back on the Form, in the Text Field properties:
- Set the "dataprovider" property to the Form variable you just created.
- Double-click to add a method for the onAction event.
- Click to create the method in "Form," name the method (e.g., onEnter), and click "Create private."
- Click "OK & Show."
- Add the following JavaScript to the JavaScript file to use the Servoy framework to implement searching bound data based on the text in the Text Field:
var search = scopes.svySearch.createSimpleSearch(foundset).setSearchText(searchText); search.setSearchAllColumns(); search.loadRecords(foundset);
Save and Launch the App
Save the form and JavaScript file, then click Run -> Launch NGClient to start the web app.
