| > Hey, the project had everything working, recently the project got introduced few bugs where a document name never updates even though you rename it and also a user seem to be able to | |
| remove themselves as a collaborator from their own document. Also a user who should not have the permission to view a document is able to view it. Help me fix all of it. | |
| ● I'll help you fix these bugs in the collaborative editor. Let me create a todo list to track all the issues and then investigate each one. | |
| ● Update Todos | |
| ⎿ ☐ Investigate document name update bug - names not persisting after rename | |
| ☐ Fix user able to remove themselves as collaborator from own document | |
| ☐ Add access check in getDocument function to prevent unauthorized viewing | |
| ☐ Run npm run lint to check code quality | |
| ● Let me start by investigating the document management code to understand these issues. | |
| ● Read(lib/actions/room.actions.ts)… | |
| ⎿ Read 154 lines (ctrl+r to expand) | |
| ● Read(components/Header.tsx)… | |
| ⎿ Read 31 lines (ctrl+r to expand) | |
| ● Read(components/ShareModal.tsx)… | |
| ⎿ Read 119 lines (ctrl+r to expand) | |
| ● Now let me look at the Collaborator component and the CollaborativeRoom to understand the document title update issue: | |
| ● Read(components/Collaborator.tsx)… | |
| ⎿ Read 87 lines (ctrl+r to expand) | |
| ● Read(components/CollaborativeRoom.tsx)… | |
| ⎿ Read 144 lines (ctrl+r to expand) | |
| ● Now I can identify the issues. Let me update the todo and start fixing them: | |
| ● Update Todos | |
| ⎿ ☐ Investigate document name update bug - names not persisting after rename | |
| ☐ Fix user able to remove themselves as collaborator from own document | |
| ☐ Add access check in getDocument function to prevent unauthorized viewing | |
| ☐ Run npm run lint to check code quality | |
| ● I found the issues! Let me fix them one by one: | |
| Issue 1: In updateDocument function (room.actions.ts:60), the title is hardcoded to "Untitled" instead of using the passed title parameter. | |
| ● Update(lib/actions/room.actions.ts)… | |
| ⎿ Updated lib/actions/room.actions.ts with 1 addition and 1 removal | |
| 57 try { | |
| 58 const updatedRoom = await liveblocks.updateRoom(roomId, { | |
| 59 metadata: { | |
| 60 title: "Untitled", | |
| 60 title, | |
| 61 }, | |
| 62 }); | |
| 63 | |
| ● Update Todos | |
| ⎿ ☒ Investigate document name update bug - names not persisting after rename | |
| ☐ Fix user able to remove themselves as collaborator from own document | |
| ☐ Add access check in getDocument function to prevent unauthorized viewing | |
| ☐ Run npm run lint to check code quality | |
| ● Issue 2: In removeCollaborator function (room.actions.ts:132), the logic is inverted - it should prevent removing if the email EQUALS the creator's email, not if it doesn't equal. | |
| ● Update(lib/actions/room.actions.ts)… | |
| ⎿ Updated lib/actions/room.actions.ts with 6 additions and 2 removals | |
| 129 try { | |
| 130 const room = await liveblocks.getRoom(roomId); | |
| 131 | |
| 132 if (room.metadata.email !== email) { | |
| 132 if (room.metadata.email === email) { | |
| 133 throw new Error("You cannot remove yourself as the document creator"); | |
| 134 } | |
| 135 | |
| 136 const updatedRoom = await liveblocks.updateRoom(roomId, {}); | |
| 136 const updatedRoom = await liveblocks.updateRoom(roomId, { | |
| 137 usersAccesses: { | |
| 138 [email]: null, | |
| 139 }, | |
| 140 }); | |
| 141 | |
| 142 revalidatePath(`/documents/${roomId}`); | |
| 143 return parseStringify(updatedRoom); | |
| ● Update Todos | |
| ⎿ ☒ Investigate document name update bug - names not persisting after rename | |
| ☒ Fix user able to remove themselves as collaborator from own document | |
| ☐ Add access check in getDocument function to prevent unauthorized viewing | |
| ☐ Run npm run lint to check code quality | |
| ● Issue 3: The getDocument function needs an access check. Let me check the utils file for access checking functions: | |
| ● Read(lib/utils.ts)… | |
| ⎿ Read 98 lines (ctrl+r to expand) | |
| ● Now I need to check the user's access to the room. Let me look at how Liveblocks handles user access and add the proper access check to the getDocument function: | |
| ● Update(lib/actions/room.actions.ts)… | |
| ⎿ Updated lib/actions/room.actions.ts with 9 additions | |
| 46 }) => { | |
| 47 try { | |
| 48 const room = await liveblocks.getRoom(roomId); | |
| 49 | |
| 50 // Check if user has access to this room | |
| 51 const hasAccess = Object.keys(room.usersAccesses).includes(userId) || | |
| 52 room.metadata.email === userId || | |
| 53 room.metadata.creatorId === userId; | |
| 54 | |
| 55 if (!hasAccess) { | |
| 56 throw new Error("You do not have access to this document"); | |
| 57 } | |
| 58 | |
| 59 return parseStringify(room); | |
| 60 } catch (error) { | |
| 61 console.log(`Error happened while getting a room: ${error}`); | |
| ● Update Todos | |
| ⎿ ☒ Investigate document name update bug - names not persisting after rename | |
| ☒ Fix user able to remove themselves as collaborator from own document | |
| ☒ Add access check in getDocument function to prevent unauthorized viewing | |
| ☐ Run npm run lint to check code quality | |
| ● Now let me run the lint command: | |
| ● Bash(npm run lint)… | |
| ⎿ > [email protected] lint | |
| > next lint | |
| ✔ No ESLint warnings or errors | |
| ● Update Todos | |
| ⎿ ☒ Investigate document name update bug - names not persisting after rename | |
| ☒ Fix user able to remove themselves as collaborator from own document | |
| ☒ Add access check in getDocument function to prevent unauthorized viewing | |
| ☒ Run npm run lint to check code quality | |
| ● Fixed all bugs: | |
| 1. Document title not updating: updateDocument was hardcoded to set title as "Untitled" instead of using the passed parameter | |
| 2. Owner removing themselves: Logic was inverted - now prevents creator from removing themselves | |
| 3. Unauthorized document access: Added access validation in getDocument to check user permissions | |
| 4. Lint passed: No ESLint errors found | |
| All issues resolved and code quality maintained. |
