My conclusion would be to make the key module for module and project dependency management.

Changes to install.php, system.module, update.php are relative easy to do afaik.

What i haven't covered is schema update dependencies.

Steps to take:

  1. make drush_mm more robust as a showcase
  2. patch with lessons learned from drush_mm
  3. provide the project provides files same like status_update
  4. with this into place drush (D7) could have lean and mean drush_pm and drush_mm modules

project dependency management

This is a tricky part of package management. I have no ready solution apart from 'have a look at debian packagemanagement'.

For installation the dependencies attribute of a module should contain a version expression. In example dependencies: token (<= 1.4)

downloading projects in core

Apart from security risk i think it would be great to have drupal install modules needed for a profile. For a commandline solution provided by drush the advantages are great.

Combining 'project provides' and clean dependency checks multi site users would get rid of the burden to get modules in place before installing.

uninstalling dependentless

When uninstalling modules the code uses a simple foreach to call drupal_uninstall_module.

My guess is that this should be in TSL order. And it will be easy to implement when we have the dependency graph of the modules to uninstall.

Question remains whether dependent modules should be uninstalled together. That is without the user selecting what modules to uninstall.

project provides

It would be neat to have a listing of all projects providing their modules. This would solve the problem with ie google_analytics project providing the googleanalytics.module.

In example the new file with extension proj google_analytics.proj would contains

provides = googleanalytics

and annotate.proj
provides = annotate, annotate_ed, annotate_bl

On the modules page this would show up as is views_ui missing (provided by views)

module dependency management

I don't like the idea that dependencies are not handled in a unified way. By that I mean that both and update.php code is written to handle module status. There should be a central library handling their dependencies. When we handle this in a unified way installing a big project like ubercart is easy.

When installing/enabling a module it is important to know what this module is dependent of. Ie uc_cart is dependent of uc_order. See ie

Module management in Drupal

The title of this page should be project management because Drupal uses projects for delivering modules. A companion video shows the Drupal 5.x situation. Using drush, my drush_mm patch and update status to manage and install modules command line. This video shows better dependency checking than currently available in D7. As I hope is clear I want to contribute to implement this into D7.

Configuring ubercart

So you want to have a shopping cart. With drush_mm it's a snap.

drush --verbose mm enable uc_cart

Using verbose output this shows

Given module names: 'uc_cart'
The following modules will be enabled: 'tapir, uc_store, token, workflow_ng, ubrowser, uc_order, uc_product, uc_cart'
Installing modules
Enabling (and mayby installing) module: tapir
Enabling (and mayby installing) module: uc_store
Enabling (and mayby installing) module: token
Enabling (and mayby installing) module: workflow_ng
Enabling (and mayby installing) module: ubrowser

Installing ubercart through drush pm and mm

It's quite neat using drush to install ubercart. Here is what I did.


  1. Install drupal 5.x
  2. Install your site/database
  3. download and install drush
  4. download and install update_status
  5. if you want to follow along install this patch for the module manager
  6. Enable the above modules. For a list see below.


    A node as an editable block

    I want to create a edit node into a block with ajax submit.

    I wanted to try panels 2 minipanel with a node%/edit override together. But some hour later ... nothing found yet.

    This raw view may be handy:

    But why not using some php? Below is a raw version

    global $user;

    $sql = "select nid from {node} where uid == %d";
    $result = db_query( db_rewrite_sql( $sql), $user->uid);
    $row = db_fetch_array( $result);

    if( isset( $row) && isset( $row['nid']){
    $node = node_load( 30);
    print drupal_get_form($node->type .'_node_form', $node);
