Build a Simple VCL Application for Asana データ
How to build a simple VCL Application to view Asana データ in RAD Studio using the CData ODBC Driver for Asana.
最終更新日：2023-06-12Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Asana, you gain access to live Asana データ within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update Asana データ. This article will walk through connecting to Asana and creating a simple VCL application with the Form Designer.
Create a Connection to Asana データ
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Asana への接続は以下のように行います。
- WorkspaceId: Asana Wrokspace のglobally unique identifier (gid) を設定すると指定されたWorkspace のプロジェクトだけを返します。Workspace Id はhttps://app.asana.com/api/1.0/workspaces から取得します。表示されるJSON にWorkspace name およびId が含まれます。
- ProjectId: Asana Project のglobally unique identifier (gid) に設定すると指定されたProject のデータだけを返します。Project ID はプロジェクトのOverview ページのURL を参照してください。/0/ の後ろの数字 です。
Asana への認証
Asana はOAuth またはOAuthPKCE 認証標準を利用しています。認証方法については、ヘルプドキュメントの「はじめに」を参照してください。
You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Asana データ.
- In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.
- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Asana.
Create VCL Applications with Connectivity to Asana データ
Follow the procedure below to start executing queries to Asana データ from a simple VCL application that displays the results of a query in a grid.
-
Drop a TFDConnection component onto the form and set the following properties:
- ConnectionDefName: Select the FireDAC connection to Asana データ.
- Connected: Select True from the menu and, in the dialog that appears, enter your credentials.
-
Drop a TFDQuery component onto the form and set the properties below:
- Connection: Set this property to the TFDConnection component, if this component is not already specified.
SQL: Click the button in the SQL property and enter a query. For example:
SELECT Id, WorkspaceId FROM projects WHERE Archived = 'true'- Active: Set this property to true.
Drop a TDataSource component onto the form and set the following property:
- DataSet: In the menu for this property, select the name of the TFDQuery component.
-
Drop a TDBGrid control onto the form and set the following property:
- DataSource: Select the name of the TDataSource.
- Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.
You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
