spec filename.rb

against a project built on Rails 3 beta and using Rspec 2 beta generated the following error (I can’t imagine why there were any issues):

/Users/chris/.rvm/gems/ruby-1.8.7-p249/gems/activesupport-3.0.0.beta3/lib/active_support/dependencies.rb:209:in `require’: no such file to load — spec/adapters/mock_frameworks/rspec (LoadError)

As you can see from the error it is in fact not running the rspec beta but rather trying to use the system’s rspec 1.3.0. Problematic, that.

Turns out the solution was to use bundle* to run the individual spec (this, of course, assumes you’re managing your gems with Bundler):

bundle exec rspec filename.rb

*In the project above I have a whole separate environment managed by RVM specifically for the latest über-stable Ruby (ruby 1.8.7 (2010-01-10 patchlevel 249) as of this writing), the Rails and Rspec beta.

This post is about how spaces in Smarty templates might trip you up. Witness the following code from a Smarty template (yes, this is kind’a like PHP but less functional and less readable):

<img src="{$deletion_item->default_image(false)}" />

<img src="{$deletion_item->default_image( false )}" />

One would tend to think, or at least I tend to think, that those two lines of HTML/Smarty code would be functionally equivalent. They look the same, save for the second developer’s preference for some extra whitespace.

However example one works with Smarty, example two throws the following error:

Fatal error: Smarty error: [in /Users/chris/Sites/dreambank/templates/en/delete_item.tpl line 42]:
syntax error: unrecognized tag: $deletion_item->default_image( false ) (Smarty_Compiler.class.php, line 446) in /Users/chris/Sites/dreambank/includes/smarty/Smarty.class.php on line 1095

So, there you have it. There’s not much more to this than to say: when working with Smarty be very careful with your whitespace.

Since January I’ve been working with a group of fantastic people to help create DreamBank, a web site who’s goal – and our hope – is to alter, for the better, the way in which we give each other gifts. DreamBank is designed to allow anyone to post their goals, or their needs, or their wants in a way that allows their friends, their family, and everyone else to help them achieve their objectives. No more mis-sized socks, no more unwanted DVDs, no more soon-to-be-lost gift cards. Just a goal and the means.

For my birthday I’d really like if you’d head over to DreamBank, check out the work we’ve been doing, read about the philosophy, sign up, create a dream and give it a try.

http://www.dreambank.org

Many thanks to you, on my birthday.
Chris

DreamBank is hiring.

http://www.dreambank.org

DreamBank is about creating an alternative to traditional gift giving in a way that helps both the planet and important social causes. We’re currently looking for one more software developer with solid experience developing MySQL-driven PHP web sites (aka LAMP).

You’ll be working with the head developer to improve and solidify the current codebase, scope and implement new features, and help plan the technical growth of the company and site.

Real-world Ruby/Rails experience is also definitely an asset as we make considerable use of Rails at DreamBank.

If you’re interested, please send your resume and cover letter in PDF format as well as a links to examples of software you’ve worked on, to info@dreambank.org.

Regards
Chris Cummer
Technical Director, DreamBank

Location: Yaletown, Vancouver
Compensation: 60-70k on contract, depending on experience.
This is a contract job.

The error occurred while evaluating nil.[]

I couldn’t find this one in the google anywhere. Turns out the cause of this is defining non-existent properties for indexing on your models (perhaps I’m the only one dumb enough to do that).

You’ll know if this is the cause because you’ll see something akin to this in your Rails console:

** ultrasphinx: warning: field f is not present in User
** ultrasphinx: warning: field descritpion is not present in Profile

Remove (or fix the spelling of) those and everything should work hunky-dory.

Update: Position filled. Thanks to all who applied.

Dreambank.org is looking to hire a software project manager in Vancouver to help chart and manage the post-launch development and growth of a funded web start-up that’s just about to go live.

Said PM would be responsible for determining the future feature-set and growth of the site, working with me (the Tech Director) to plan the schedule and deliver the features, work with marketing, with the customers, and so forth. Any PM worth their salt will be able to describe this job position far better than I (and if you’re off-put by that remark you’re probably not the right fit, sorry.)

Said person must have successfully managed and delivered at least one relatively sizable commercial software project in the past as the PM. That is the minimum requirement. No developers looking to advance their careers or PMs from other industries looking to get into software. You know software, and you know you know it.

If you sound like this person and you live in Vancouver and you’re interested and think you’re qualified, kindly get in touch with me at either chris@postal-code.com or chris@dreambank.org. I’d love to talk to you, fill you in and find out more about you.

Cheers
Chris

chris@karnak:~$ sudo apt-get install build-essential

there’s a good chance it will fail with this error:

Failed to fetch cdrom:[Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20071016)]/pool/main/g/gcc-4.1/g++-4.1_4.1.2-16ubuntu2_i386.deb Hash Sum mismatch

If so, open up your sources file:

chris@karnak:~$ sudo nano /etc/apt/sources.list

and comment out the line that references the CD-ROM (its probably the first one):

deb cdrom:[Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20071016)]/ gutsy main restricted

Rebuild your repositories:

chris@karnak:~$ sudo apt-get dist-upgrade

and then try re-running the build-essential command. It ought to work now.

Fatal error: Call to undefined function imagecreatefromjpeg()

It seems that in addition to damaging any installation of MySQL and Apache the upgrade to 10.5 also over-wrote my PHP install with an inferior, no-GD included version, which is a big feckin’ problem Apple.

Some googling turned up the following simple (<- that's sarcasm) solution to fix Apple's installation fubar:

Okay, here is the complete instruction on how to do this. Michel L already posted a very good message on how to build PHP with GD enabled, so i just combine all the answers in one step-by-step guide.

1. Download the Apache2 source from http://httpd.apache.org/download.cgi (latest version is 2.2.6) and extract it.
2. Open Terminal and go to that directory. If you extract sources into your Downloads folder, type “cd ~/Downloads/httpd-2.6.6″ and hit return
3. Type “./configure –enable-layout=Darwin –enable-mods-shared=all” and hit return
4. Wait for the process to complete and then type “make” and return
5. Wait for the process to complete and then type “sudo make install” and return

Now you have Apache2 built and installed and it should run perfectly.

Then, follow the Michel L instructions. I will copy them here with several modifications:

Install libjpeg ***
Get latest Stable SRC:

http://www.ijg.org/files/

tar zxvf jpegsrc.v6b.tar.gz

cd jpeg-6b

cp /usr/share/libtool/config.sub .

cp /usr/share/libtool/config.guess .

[Update: WordPress fiddles with double-dashes so the compiler flags in the following statements are incorrect (ie: –sysconfdir=/etc should be preceded by two dashes, not one). In the comments Mark has posted a corrected version down in the comments that you should follow. I'd correct them in the article but they are in fact correct in the article content; it appears WordPress mucks with them elsewhere, alas. - Chris]

env CFLAGS=”-O -g -arch i386 -arch ppc” LDFLAGS=”-arch i386 -arch ppc” ./configure –prefix=/usr –sysconfdir=/etc –localstatedir=/var –mandir=/usr/share/man –enable-shared –enable-static

make

sudo make install

sudo ranlib /usr/local/lib/libjpeg.a

Install libpng ***
Get latest Stable SRC with config script

http://www.libpng.org/pub/png/libpng.html

tar jxvf libpng-1.2.22.tar.bz2

cd libpng-1.2.22

env CFLAGS=”-O -g -arch i386 -arch ppc” LDFLAGS=”-arch i386 -arch ppc” ./configure –prefix=/usr –sysconfdir=/etc –localstatedir=/var –mandir=/usr/share/man –disable-dependency-tracking

make

sudo make install

sudo ranlib /usr/local/lib/libpng.a

The same procedure with PHP sources, and configure line should look like this:

./configure –prefix=/usr –sysconfdir=/etc –localstatedir=/var –mandir=/usr/share/man –infodir=/usr/share/info –with-apxs2=/usr/sbin/apxs –with-curl –with-gd –enable-exif –enable-fastcgi –enable-zip –with-jpeg-dir=/usr/src/libjpeg –with-ldap=/usr –with-kerberos=/usr –with-zlib=/usr –enable-ftp –enable-sockets –with-iodbc=/usr –with-config-file-path=/etc –with-openssl –with-xmlrpc –with-xsl=/usr

If you have MySQL installed, add the following options to the PHP configure command (let’s assume you have your MySQL in /usr/local/mysql directory):
–with-mysql=/usr/local/mysql –with-mysql-sock=/var/mysql –with-mysqli=/usr/local/mysql/bin/mysql_config

Then, run “make -j3″

And then, as usual, “sudo make install”

Note that PHP configure and build processes will take much time even on fast machine.

After all, go to “System Preferences > Sharing” and uncheck “Web Sharing” checkbox, then wait a bit and check it again. Now you should have your Apache+PHP up and running.

Screw that. From now on I’m using my Ubuntu machine for all PHP development until Apple finally starts shipping a decent development install or at the very least ships an OS that won’t fuck with mine.

The errors I was getting were:

[error] [client 10.0.1.198] client denied by server configuration: /Users/chris/Sites/index.html

AKA: the dreaded 403.

Solution: In the Terminal do the following:

sudo cp /etc/httpd/users/chris.conf /etc/apache2/users/

Replacing the name of your user for “chris”. Restart Apache2:

sudo apachectl restart

You should at least now be able to see your files, even if the PHP ones are showing up as text.

To get PHP working again, once more in the Terminal:

sudo nano /etc/apache2/httpd.conf

Find the line

#LoadModule php5_module libexec/apache2/libphp5.so

and uncomment it (ie: delete the # from the front). Save that file. Restart Apache2 per above.

Basic PHP should now be working, but in my case phpMyAdmin wasn’t because once again the location of mysql.sock has changed.

To get that working again, follow the instructions I posted over a year ago in “phpMyAdmin, ‘Error #2002 – The server is not responding’, and OS X 10.4.4″.
