by Alex Johnson 57 views

Introduction

In the realm of Content Management Systems (CMS), Craft CMS stands out for its flexibility and multi-site capabilities. However, a peculiar issue arises when editing entries across multiple sites within a Craft CMS installation. This article delves into a specific problem where editing an entry in one site triggers a "saving" state in another, even when there should be no interaction between the sites. We will explore the issue, its implications, steps to reproduce it, expected behavior, actual behavior, and relevant version information. Understanding and addressing this issue is crucial for maintaining a seamless and intuitive user experience in multi-site Craft CMS environments.

Understanding the Multi-Site Editing Issue in Craft CMS

When working with a multi-site Craft CMS setup, it's essential that changes made on one site do not inadvertently affect others, especially when dealing with non-translatable content. The core issue at hand is that when a user edits a Single (a type of content in Craft CMS) on Site A, users on Site B might see a "saving" spinner or receive notifications indicating that the entry is being edited, even if the Single is not shared or translatable between the sites. This misleading behavior can cause confusion and concern among content editors, as they might worry about unintended changes or data loss. Additionally, the system might present users with options to undo changes in other sites, which they should not have access to in the first place. This article will provide a detailed breakdown of the problem, explore the steps to reproduce it, and discuss the expected and actual behaviors observed in Craft CMS.

Detailed Description of the Problem

The problem manifests in a few key ways. First, when a user on Site A edits a Single, users on Site B (who are also viewing the same Single) see the "saving" spinner, indicating that changes are being made. This is particularly problematic because these Singles are often not translatable between sites, meaning that edits in one site should not affect the other. Second, users on Site B might receive a prompt to undo changes made by the user on Site A, even though they lack the necessary permissions to do so. This creates a confusing and potentially disruptive user experience.

Another facet of the issue is the presence of notifications indicating that another user is viewing the entry, even when this is technically not the case. For example, if User X and User Y have access to different sites and are logged in separately, they might still see messages stating that "User X is also viewing this entry," even if they are working on distinct sites with no content overlap. This false indication can lead to unnecessary worry and mistrust among users, especially in environments where multiple teams manage content independently. Addressing these issues is critical to ensuring a smooth and error-free workflow for content editors in multi-site Craft CMS setups.

Steps to Reproduce the Issue

To effectively address the multi-site editing issue in Craft CMS, it is crucial to understand how to reproduce it consistently. The following steps outline the process to replicate the problem:

  1. Set up a multi-site CMS:

    • Begin by creating a Craft CMS installation with multiple sites configured. This involves setting up distinct sites within the CMS, each with its own domain or subfolder.

  2. Create a non-translatable Single:

    • Within the CMS, create a Single content type that is not translatable between sites. This means the content within this Single is unique to each site and should not be shared or synchronized.

  3. Grant user access to each site:

    • Create user accounts and grant them access to different sites. Ensure that some users have access to multiple sites to observe the full scope of the issue.

  4. Simultaneous editing:

    • Log in to the CMS using two different user accounts, each with access to a different site. Navigate to the same non-translatable Single on both sites. Have both users simultaneously edit the Single on their respective sites.

By following these steps, you can observe the issue where editing a Single on one site triggers a "saving" state or prompts on another site, even though the content should be isolated. This replication allows for a clearer understanding of the problem and aids in identifying potential solutions.

Expected Behavior vs. Actual Behavior

Expected Behavior

In a properly functioning multi-site Craft CMS setup, the expected behavior when editing non-translatable Singles is that each site operates independently. Specifically:

  • Isolation of Editing States: When a user edits a Single on one site, users on other sites should not see any indication of this activity. There should be no "saving" spinners or prompts suggesting that the content is being modified elsewhere.
  • No Cross-Site Notifications: The system should not display notifications indicating that another user is viewing or editing the entry if those users are on different sites and the content is not shared between them.
  • Permission Integrity: Users should not be given options to undo changes made on other sites, especially if they do not have the necessary permissions to access or modify those sites.

Actual Behavior

However, the actual behavior observed in Craft CMS deviates from these expectations. The primary issues include:

  • Triggered "Saving" State: When a user edits a Single on one site, users on other sites may see the "saving" spinner, even if the Single is not translatable between the sites. This creates a false impression that changes are being synchronized across sites.
  • Misleading Notifications: Users may receive notifications stating that another user is viewing the entry, even when those users are on different sites with no content overlap. This can cause confusion and concern about unauthorized access or modifications.
  • Incorrect Permission Prompts: The system may present users with options to undo changes made on other sites, which they should not have access to. This not only confuses users but also raises security concerns.

This discrepancy between expected and actual behavior highlights the need for a solution that ensures proper isolation and communication within a multi-site Craft CMS environment.

Version Information and System Details

Understanding the specific versions and system configurations involved in an issue is critical for accurate diagnosis and resolution. In this case, the following details were reported:

  • Craft CMS Version: 5.8.12
  • PHP Version: Not specified in the original report
  • Operating System and Version: Not specified in the original report
  • Database Type and Version: Not specified in the original report
  • Image Driver and Version: Not specified in the original report
  • Installed Plugins and Versions: No specific plugins were listed

From the provided information, the Craft CMS version is a key piece of data, as it helps narrow down the scope of potential bugs or compatibility issues. The absence of information regarding PHP version, operating system, database type, and image driver makes it challenging to pinpoint the exact cause of the problem. It is recommended to gather this additional information to facilitate more effective troubleshooting.

Importance of Version Details

Craft CMS, like any software, undergoes regular updates and patches that address bugs and improve functionality. Knowing the specific version in use helps determine whether the issue is a known bug that has already been addressed in a later release. If the problem persists in version 5.8.12, it may be necessary to investigate other factors such as server configuration, database settings, or installed plugins. Providing a comprehensive system overview can significantly aid in the debugging process and ensure that any proposed solutions are compatible with the existing environment.

Potential Causes and Solutions

Addressing the multi-site editing issue in Craft CMS requires a thorough understanding of its potential causes and effective solutions. Several factors could contribute to the observed behavior, including session management, real-time collaboration features, and database synchronization.

Potential Causes

  1. Session Management: Craft CMS uses sessions to track user activity. If session data is not properly isolated between sites, it can lead to cross-site interference. This might result in one user's actions triggering events on another site.
  2. Real-Time Collaboration Features: Craft CMS includes features that provide real-time updates when multiple users are editing the same content. If these features are not correctly configured for a multi-site environment, they may cause unintended notifications and saving states across sites.
  3. Database Synchronization: Issues with database synchronization can lead to inconsistent states across sites. If changes are not properly isolated, updates on one site might inadvertently affect others.

Potential Solutions

  1. Review Session Configuration: Ensure that session settings are configured to isolate sessions between sites. This may involve setting unique session cookies for each site or using a database-driven session handler that correctly separates session data.
  2. Adjust Real-Time Collaboration Settings: Examine the real-time collaboration settings in Craft CMS. If possible, configure these settings to respect site boundaries, ensuring that updates are only triggered within the relevant site.
  3. Optimize Database Synchronization: Verify that database synchronization mechanisms are properly configured. Ensure that changes are scoped to the appropriate site and that transactions are isolated to prevent cross-site contamination.
  4. Plugin Compatibility: Check for compatibility issues with installed plugins. Some plugins may not be fully compatible with multi-site setups and could cause unexpected behavior.
  5. Craft CMS Updates: Ensure that Craft CMS is updated to the latest version. Updates often include bug fixes and improvements that address multi-site issues.

By systematically addressing these potential causes and implementing the corresponding solutions, you can significantly mitigate the multi-site editing issue in Craft CMS.
