Overview

Authorization of a PostgreSQL Account

The first time you add a PostgreSQL card to a FLO, you will need to create a configuration. This will allow you to connect to your account, save your account information, and reuse that configuration next time you build a FLO with the connector. That way, you don’t have to sign in every time you want to build a FLO with this Connector. Instead, use the configuration you have already set up. You can create and save multiple configurations and share them with your teammates.

Here’s how to set up a new configuration in PostgreSQL:

  1. Enter in an Account Nickname. This should be unique so if you are connecting multiple PostgreSQL accounts you will be able to tell them apart (e.g. “Postgres 1”).
  2. Enter your PostgreSQL Username and Password.
  3. Enter the Database Host, the server that hosts your database (e.g. “stampy.db.elephantsql.com”). Do not include the protocol or port.
  4. Enter your Database Name, the unique name of your database on the server.
  5. Enter the Database Port, the port that your database can be accessed at. The default port for PostgreSQL is  ”5432”. You can find your port in the URL used to access your database after the hostname (e.g. “postgres://[username]:[password]@[hostname]:5432/[database name]“).
  6. Click Create to finish this configuration.

    Actions

    • Build Row Object

      Creates a row of data for an existing table in PostgreSQL. Good for use with the ‘Create Multiple Rows’ Action. If you wish to add a single row, use the ‘Create Row’ Action.

      Options

      • Table Name (drop down menu): A list of existing tables within your database. Choose the table which you wish to add to.

      Input Fields

      Input fields are dynamically generated based on existing columns in your table.

      Output Fields

      • Row Object (object): The row object that you can use for the ‘Create Multiple Rows’ Action.
    • Create Multiple Rows

      Inserts rows into a table in PostgreSQL. Use the ‘Build Row Object’ Action to create the Row Objects that you can drag and drop into this card.

      Options

      • Table Name (drop down menu): A list of existing tables within your database. Choose the table which you wish to add to. Or choose “–Insert Table–” if you wish to add the table as an input value at runtime.

      Input Fields

      if Table Name is “–Insert Table–”:

      • Table
        • Table Name (text): The name of the table you will be adding to.
      • Rows
        • Row Objects (objects): Add in Row Objects that will be added to the table.
