Calling Cloud Database Methods in WeDa JavaScript Methods

Background​

Users want to directly call cloud database queries using JavaScript in the WeDa editor.

Implementation Process​

  1. Define a js method in the WeDa editor. The code is as follows:
export default async function ({ event, data }) {
  const db = (await $w.cloud.getCloudInstance()).database();
  db.collection("tableName") // tableName is the corresponding collection name
    .doc("dataId") // dataId is the _id of the data record
    .get()
    .then((res) => {
      console.log(res.data);
    });
}
Note

$w.cloud.getCloudInstance obtains the initialized CloudBase instance in the current runtime environment

  1. Run the js method and print the query results
