💡 Hint

Common Mistakes

Using 'collection' instead of 'member' for single resource actions.

Using 'resource' or 'resources' keywords incorrectly inside the block.

The 'toggle' action acts on a single post, so it must be inside a member block.

Common Mistakes

Swapping member and collection keywords.

Using 'resource' or 'resources' inside the block incorrectly.

'archive' applies to the whole collection, so it goes in collection. 'publish' acts on one event, so it goes in member.

💡 Hint

Common Mistakes

Putting member routes inside collection block.

Using 'resource' keyword incorrectly.

'activate' and 'deactivate' are actions on individual users, so they go in member. 'stats' is for the whole collection, so it goes in collection. 'profile' is also a member route.
