The Devel module provides tools and pages for Drupal developers to inspect and debug site functionality. It offers features like a development toolbar, entity property views, variable debugging, user masquerading, and bulk content generation.
Introduction
Devel module contains helper functions and pages for Drupal developers and inquisitive admins:
- A block and toolbar for quickly accessing devel pages
- A menu tab added to entities to give access to internal entity properties
- Urls created to view the internal entity properties even when there is no menu tab, for example /devel/paragraph/n
- Debug functions for inspecting a variable such as
dpm($variable) - Debug a SQL query
dpq($queryor print a backtraceddebug_backtrace() - A block for masquerading as other users (useful for testing)
- A mail-system class which redirects outbound email to files
- Drush commands such as
fn-hook,fn-event,token,uuid, anddevel-services - Devel Generate. Bulk creates nodes, users, comment, taxonomy, media, menus, block content for development. Has Drush integration.
This module is safe to use on a production site. Just be sure to only grant access development information permission to developers.
Collaboration
- https://gitlab.com/drupalspoons/devel is our workplace for code, MRs, and CI.
- Create a personal fork in order to make an MR.
- We plan to move bck to drupal.org once it uses Gitlab for issues.
- We auto-push back to git.drupalcode.org in order to keep Security Team coverage and packages.drupal.org integration.
- Chat with us at #devel on Drupal Slack.
