Corralling permissions into a grid

I've just released Permissions Grid. It does what the name suggests: it presents related permissions in a grid, rather than the usual long list.

How are permissions structured into a grid? Well, only the ones that form natural groups are included: every set of permissions of the form 'create foo, edit foo, delete foo, create bar, edit bar, delete bar' is turned into a matrix of checkboxes with the verbs 'create, edit, delete' along the top, and the objects 'foo, bar' along the top. When modules such as node, taxonomy, and commerce define related permissions for nodes, vocabularies, and products respectively, that gives you something like this:

Git tricks: repatching for an issue branch

My workflow for making patches is to use a feature branch for a single issue. Whether you're a contributor or a maintainer it lets you advance the fixing of the problem in small increments, and safely experiment knowing you can roll back.

But where it goes wrong is when your patch is superseded by a newer one in the issue queue, and you want to work on it some more. How do you update your branch for the ongoing work? As ever, with git there's a way.

Let's start with the basics first: you're making a feature branch to work on an issue. I tend to follow the naming pattern '123456-fix-all-the-bugs', but for this example I'll call it 'issue'.

// Make a new branch and switch to it.
$ git co -b issue
// Make lots of commits.
// Ready to make a patch:
$ git diff > 123456.project.issue.patch

Moving a git local branch from one local to another

You're maybe at one of the many Drupal Co-worker Friday events that are taking place around the world today. You've packed up your laptop and your lunchbox, and you're looking forward to a day out of the house with some human contact.

But yesterday you were halfway through a big piece of work on your project. And you were using a git local branch, of course. Why? Because it keeps your work isolated off the main development branch, allowing other work to continue independently. And because while your commits are only local you're free to reorder them, edit the log messages, fixup mistakes as if they never happened, and so on. In fact, if you so choose, merging your local branch in with the --squash option makes it look like you made all of the work in a single, perfect commit. Wow!

A concept for limiting taxonomy terms by common fields

There are several modules that provide taxonomy term widgets that are more efficient at drilling down into large and complex vocabularies of terms, but I've not yet found something that just limits terms in some way.

The use case is somewhat like this: I have products that are classified by sport and by team. And teams can be rugby teams or football teams, and so on. Having one vocabulary per type of team feels somewhat weak, but putting them all in one vocabulary means the user has to wade through a lot of irrelevant terms.

So I've been thinking of ways to limit the terms in the field widget. I don't think this is something I'm going to develop (for reasons that will become clear), but it's just a wacky idea[*] I'm putting out there.

Dynamically changing Views table joins

I've recently had cause to make Views make joins to tables in peculiar ways. Here's some notes on the peculiar things I did with the views_join class to accomplish that.

First of all I'll briefly recap how we define a table to Views. Each item in the $data array returned to hook_view_data() represents all the information about a table. Each key in the array is a field on that table (well, or pseudofield), except for the 'table' key which has the basic data about our table, like this:

It's Amazing What You Find: Crusty Bits of the Menu System

I've been poking in the innards of the menu system the last few days. This is due to yet another client wanting to do something that goes completely against the grain of Drupal.

The Oxford Comma

Here's a little function I wrote today because I needed to be able to turn a list of between one and three items into a string like 'apples, oranges, and pears', 'apples and pears', or just 'stairs'.

I figured I might as well handle everything in one place, and throw in the option to have an 'or' instead of an 'and'. There may be occasions you don't want the Oxford comma, but I can't think of any.

Using Constants For Permission Names: WHY?

I keep seeing this sort of thing in so many modules:

define("MY_MODULE_PERM_ACCESS_WIDGETS", 'access widgets');
// Names changed to protect the guilty ;)

Am I missing something, or is this utterly pointless?

Once & Only Once: The Conversion To Drupal 7's FieldAPI

I'm not a fan of repeating myself, or of doing the same work twice. So when I first got a look at FieldAPI back at DrupalCon Paris, my thought after 'Wow this is going to change everything,' was 'Every module that converts its custom data storage to this is going to be doing the same work, over and over'.

Help needed: using jQuery to show passwords as you type

Today I found an article about password usability, which suggested that showing users what they type for their passwords is an improvement to usability.

You can try a working demo, which adds a 'show password' checkbox.

This had me wondering whether this is a feature we should consider having in Drupal.
