Learning CakePHP: Foreign Key Constraint Violation

2010-02-24T09:04:36-04:00

Readability. locations is really just a lookup table. Whenever possible, I like to be able to open a table that uses lookup data and have it be meaningful without requiring the extra step of writing SQL to join the lookup. In this case, opening the events table would show a location like MAINTENT. Just by looking at the event record, I can tell where it’s happening.

You’re right that Cake may be smart enough if it was an int, but I use UUIDs. That’s just a char datatype so it may not behave any differently. It’s a good point to test, though. I may try it.

Why do you use the varchar datatype?
I don’t allow users to enter “no relation” so I’m not sure, but if you use a proper datatype for id’s and foreign keys (like unsigned int), Cake might be smart and use null instead of an empty string for unset FK’s.
If it doesn’t do that, I suggest to file a bug report.

Change Key Bindings in Pidgin

2010-02-22T18:04:29-04:00

OK. I fixed it. the point was “System->Preferences->Appearance:Interface:Editable Menu Shortcut Keys”
I was wandering around and to see what this option is, I just checked it. Then probably I have assigned the shortcut key for “enable logging” to be the letter a, by mousing over this menu option and simultaneously pressing “a”.
Now it works.

Hey, I have exactly the same problem with “A” and it stands for Enable “Logging”!
I did the same thing, but it doesn’t work. I realized that I should have GTK read my shortcut keys:

But I don’t know how to do that!
Do you have any idea, what can I do?

On macbook pro if you open system preferences -> trackpad it will show you a video for each shortcut and what each does. For example, three fingers on the trackpad scrolling left or right navigates forward or back in the browser…

CakePHP: Recursive Finds

2010-02-04T11:01:29-04:00

OMG! I agree the docs ARE confusing – In most cases the examples that explain the point in questions is very basic – and for a begginner this does not help.

Take the example of recursive finds, the example isnt that clear, well I guess it is if you read:

http://book.cakephp.org/view/439/recursive

however what isnt that clear is specifically what tables does the example use, but more importantly their relationships.

It’s not so simply to bring a not bad essay paper, essentially if you are engaged. I consult you to set buy essay and to be spare from distrust that your work will be done by paper writing services

Thanks, Rob. Applying the knowledge I gained from your excellent explanation, and after looking at the help listing for xte, I was able to make any button do things like go back/forward between browser pages, go home/end of page, pageup/pagedown, etc. If only all tips on help forums were as clear as yours…

Thanks again

Synchronizing Firefox Through Dropbox

2009-12-30T09:34:44-04:00

I do this – or a “light” version of this – for lots of apps (Komodo Edit, Apache, bash, git, etc.). I’m not sure I understand why you had to add firefox-bin, but I’m glad it’s working for you.

Great idea!

I would love to try this other programs!

I had to add firefox-bin to the terminal command to get it to open properly.

Does anyone know if you add another account using the same technique it will write over/erase all of the synced files that are in the drop box?

You have to choose to use any profile that is already in use. Try quitting Firefox and restarting with the -p parameter.

My main profile is on windows & I did all like you’ve writen.
When I run firefox with parrametre “-p” on linux and I choose “dropbox” profile, I have this error message:

Firefox cannot use the profile “dropbox” because it is in use.

To continue, close the running instance of Firefox or choose a different profile.

MacBook Pro Touchpad Tricks

2009-12-11T09:45:26-04:00

i know some other ‘tricks’, not just scrolling, although i am not sure what kind of mac they will work for, I have the latest version of the macbook pro, here are some tricks i have found.

1) place one finger on the pad around where u would click, but dont actually click, with 3 other fingers, slide them from the side to above your first finger, and if you have tabs open on a browser, it allows u to move back and fourth between them.

2) similar to the first one put ur finger above the clicking area, but dont click, with the three other fingers, move them in more of an upwards movement, this will push any windows you have open off the screen. do the same but move down to get them back
