Getting a List of Database Tables in CakePHP

I ran into an interesting problem today. What I wanted to do was know if a table didn't exist in my CakePHP application. What happens- a cakeError is thrown everytime a database table doesn't exist. This is really annoying...I think it would be beneficial to be able to tell Controller::loadModel() to return false instead of an error message. That's not the case. Here's how I got around it (with thanks to Miles Johnson):
Use Cake's Database Connection Manager to Return a List of Database Tables
This works perfectly. The only issue is that now you are dealing with table names instead of Model Names. Not a huge issue, but something to keep in mind. Here's the code to get an array of all the database table names (from anywhere within your application!):
- $db = ConnectionManager::getDataSource('default');
- $tables = $db->listSources();
- $this->loadModel('MyTable');
- //logic with dynamically loaded model
- }
A note about $useTable = false (and why it didn't work for me)
Some of the CakePHP newsgroup postings talk about setting your model's $useTable variable to false. Well that didn't work for me because I needed to dynamically tell if the table existed. There was no way for me to say $this->ModelName->useTable = false. I wasn't going to change the model.php file...a table does exist and I didn't want to tell my application otherwise. Someone mentioned setting it in AppModel, but that just scares me.
Cheers,
