get()

Retrieves a specified document from storage.

uniface.datastore.get(DocId)

Example: uniface.datastore.get('songs_dsp')

Arguments

DocId—the identifier of the document that you want to retrieve.

Return Value

Returns a JavaScript Promise object. If the promise is resolved, the specified document is returned as an object. For example:

{
  "_id": "songs_dsp",
  "_rev": "1-A6157A5EA545C99B00FF904EEF05FD9F"
  "title": "Rock and Roll Heart",
}

Otherwise, an error is returned. For more information, see Promises and Errors.

Using get()

Assuming the data has been stored in a local database under the _idsongs_dsp, the following code retrieves the data from local storage, and loads it into the current DSP instance: 

// Look for the doc with id 'songs_dsp' and load its data to the current instance.
uniface.datastore.get('songs_dsp').then(function (vData) {
  uniface.getInstance().setData(vData.title);
}).catch(function (err) {
  console.log(err);
});
