You just have to write some code!  Like I said, not through [validation] rules.

its not about not wanting to write code… its about doing it the most elegant way….Checking that the project doesnt already have a stage with that year value is trivial to write.. I just dont think its something that belongs in my controller…. I dont understand why you say its not a validation issue when you defined the function unique_pair

@NachoF

I didn’t define the function - it’s from DataMapper.  And it’s designed to work with normal fields.  It’s designed specifically to mirror the functionality of a compound primary key.

The reason field validation rules won’t work against relationships is that the relationships aren’t set until after the object has been saved.  You might be able to make a related validation rule work, but I don’t usually do much with those.

The reason I think this absolutely belongs in a controller is this is a business logic function.  This is something that needs to be enforced through application logic.  I don’t understand why it would ever be possible for the user to pick an invalid combination in this instance.  In general, it’s more a matter of opinion, and design choice.

Hi.
I tried to use datamapper, but I only get this error, when i try to create models..
Fatal error: Class ‘DataMapper’ not found in /Applications/MAMP/www/application/models/_template.php on line 22

If i try to remove _template.php file, I get no errors, until i create a new model, where I inherit from DataMapper.. Then i get the same error, with a reference to another file of course..

Why do this error occour? Eclipse do find DataMapper, so the file is there, and I have followed the installation guide..

I just set up my datamapper models and when trying to initiate any one of them in my controller (e.g. $request = new Request() ), I get this error message:

Fatal error: Cannot access empty property in C:\Users\Scofield\Documents\My Dropbox\Dev\xampp\htdocs\dma\system\application\libraries\datamapper.php on line 2352

Any help rendered will be greatly appreciated

Also, please try doing a little troubleshooting.  There are tips at the top of that page.

Is there away to set up a relationship between two tables in two databases? (on the same server, with the same login credentials)

@squawk
Nope.  DMZ needs both objects on the same database.

However, you could manually simulate the connection.  It’s not officially supported, but DMZ has the ability to talk to multiple databases.  There’s just no way for it to understand the relationship.

Hi people, and hi OverZealous. I belive this is my very first post. Beeing a front end developer who the last year or so have started to pay interest for php, oop and CI I can’t tell you enough how much this forum has helped me. Yet I have coded very little, mostly been reading, and it’s a great feeling for someone at my (low) level to actually feel that something is being learnt. It feels like I’m slowly getting a grip on things.

Your forum posts, OverZealous, and the documentation for DMZ, has helped me so much. So I just want to give you a big thank you. Two other users from which contributions I also learned a great deal is wiredesignz and dexcell. So big thanks to these guys as well. I guess this probably should be in another thread, but from the beginning I was just about to thank you OverZealous for DMZ 😊

Take care, and keep up the fantastic work! I might be back with some silly questions later on!

I’ve got a bit of trouble with relationships:

$b = new Buyer();
$b->order_by('updated', 'desc')->get($limit, $offset);
$b->user->get();
$b->place->get();
$b->objtype->get();

Foreaching through $b works fine and I can echo all the fields from the buyers table, however, ALL of the relationship fields (like $buyer->user->username or $buyer->objtype->name) are empty. I checked that all the relationships are set up right in the models

All the fields from the joined tables are set, it is just that they are empty. Or am I accessing them wrong?

The other thing that I noticed is that all the queries from the joined tables seem to have an additional WHERE clause. (What are they for?)

WHERE `ksv_buyers`.`id` = 353

353 is the id of the first record that is being returned. The relationship fields are also not filled for this record.
