This is a [seemingly] simple question and I'm hoping I get a quick answer as my afternoon depends on the answer :D
In Codeigniter, if I create a named instance of a model in another model, what is the scope of the new object?
hope this clarifies a bit more:
If in 'user_model' I create an instance of 'logging_model' thus:
$this->load->model('logging_model', 'logging');
if in 'post_model' I need access to the new 'logging' instance created in the user model, do I just call the same piece of code in the constructor/function that I need to have access?
so if user_model sets an attribute of $this->logging->posts = 0;
I want post_model to access the 'posts' attribute with the newly set value, would just by instantiating the logging_model with the same instance name (logging) inside posts_model give access to the object created by user_model?
do I just call the same piece of code in the constructor/function that I need to have access?
No - if you need the model in multiple places you should call it in config/autoload.php
To load a model you will require to write
$this->model->(your model name here)
To load globally you will require to call your model in application/config/autoload.php
$autoload['model'] = array('your model1', 'your model2');
I hope this is helpful.
