Customizing the labels

You can easily customize the labels displayed in the UI by mentioning custom values in key_label, value_label, action_text, and delete_text properties when defining the field.

field :meta, # The database field ID
  as: :key_value, # The field type.
  key_label: "Meta key", # Custom value for key header. Defaults to 'Key'.
  value_label: "Meta value", # Custom value for value header. Defaults to 'Value'.
  action_text: "New item", # Custom value for button to add a row. Defaults to 'Add'.
  delete_text: "Remove item" # Custom value for button to delete a row. Defaults to 'Delete'.

Enforce restrictions

You can enforce some restrictions by removing the ability to edit the field's key by setting disable_editing_keys to true. Be aware that this option will also disable adding rows as well. You can separately remove the ability to add a new row by setting disable_adding_rows to true. Deletion of rows can be enforced by setting disable_deleting_rows to true.

field :meta, # The database field ID
  as: :key_value, # The field type.
  disable_editing_keys: false, # Option to disable the ability to edit keys. Implies disabling to add rows. Defaults to false.
  disable_adding_rows: false, # Option to disable the ability to add rows. Defaults to false.
  disable_deleting_rows: false # Option to disable the ability to delete rows. Defaults to false.
