Extension. Get all TinyDB. Save TinyDB content to CloudDB

[Juan_Antonio]

• Using blocks we can read the entire TinyDB and save its content in a file, here is an example:
  https://community.appinventor.mit.edu/t/save-tinydb-to-file-and-clouddb-retrieve-the-information-from-clouddb-and-insert-it-into-tinydb/42920

• Here we are going to use an extension to get the content of a TinyDB in JSON and CSV format. We can also load a TinyDB with the content of a text file in CSV format.

You can download the extension from:
http://kio4.com/appinventor/256_extension_tinydb_obtener.htm

1.- Get the content of a TinyDB in JSON and CSV format.

Notice that each TinyDB has a different Namespace:

2.- Copy the content of a csv file into a TinyDB.

p256_Get_TinyDB_v2.aia (11.3 KB)

• We have this file in the asset: africa.csv

Egipto,"El Cairo"
Argelia,"Argel"
Libia,"Trípoli"

• We want to load that content into TinyDB1 with Namespace: Tiny_ONE

• Using the File component we copy the africa.csv file into ASD, then we load its content into TinyDB1

3.- Save a TinyDB in CloudDB. Get her back.

• We create a TinyDB and show its content using Button2.

• Through the Csv block we obtain the entire TinyDB and save all its content in CloudDB with the backup label.

• We delete the entire TinyDB using the ClearAll block.

• We press Button2 again to show its content and we observe that it is deleted.

• Press Button5 to obtain the content of the TinyDB stored in CloudDB and save it in the file: backup.txt

• We load the backup.txt file in the TinyDB with Namespace: Tiny_ONE

4.- Upload and download file to FireBase.

Instead of saving the information in CloudDB, we can upload the backup.txt file to Firebase, for that we follow the tutorials of @TIMAI2
