Metadata

You can attach metadata for each project, task, user or for the whole application. Metadata are custom fields, it's a key/value table.

For example your plugin can store external information for a task or new settings for a project. Basically that allow you to extend the default fields without having to create new tables.

Attach metadata to tasks and remove them


// Return a dictionary of metadata (keys/values) for the $task_id
$this->taskMetadata->getAll($task_id);

// Get a value only for a task
$this->taskMetadata->get($task_id, 'my_plugin_variable', 'default_value');

// Return true if the metadata my_plugin_variable exists
$this->taskMetadata->exists($task_id, 'my_plugin_variable');

// Create or update metadata for the task
$this->taskMetadata->save($task_id, ['my_plugin_variable' => 'something']);

// Remove a metadata from a project
$this->projectMetadata->remove($project_id, my_plugin_variable);

Metadata types

  • TaskMetadata: $this->taskMetadata
  • ProjectMetadata: $this->projectMetadata
  • UserMetadata: $this->userMetadata
  • Settings/Config: $this->config

Notes

  • Always prefix the metadata name with your plugin name
