datasette-edit-schema

Datasette plugin for modifying table schemas

Features

• Add new columns to a table
• Rename columns in a table

• Re-order the columns in a table
• Rename a table
• Delete a table
• Change the primary key of a table to another column containing unique values

Installation

Install this plugin in the same environment as Datasette.

pip install datasette-edit-schema

Usage

Navigate to /-/edit-schema/dbname/tablename on your Datasette instance to edit a specific table.

Use /-/edit-schema/dbname to create a new table in a specific database.

By default only the root actor can access the page - so you'll need to run Datasette with the --root option and click on the link shown in the terminal to sign in and access the page.

Permissions

The edit-schema permission governs access. You can use permission plugins such as datasette-permissions-sql to grant additional access to the write interface.

These permission checks will call the permission_allowed() plugin hook with three arguments:

• action will be the string "edit-schema"
• actor will be the currently authenticated actor - usually a dictionary
• resource will be the string name of the database
