MVC best practice

Question

I'm new to MVC (i'm using codeigniter) and was wondering where I should put a "cut_description" function.

My model retrieves a list of events including their description. If the description is too long, I would need to cut it after the first n words, and add a "read more" link, so the view doesn't get too cluttered.

What would be the best practice?

1. add the logic to cut after n words to the model
2. add the logic to the controller
3. add it to the view?

I think 3 would be the easier (I have to loop through results anyway), but I'm not sure this would comply with MVC.

What do you think?

Answer 1

If you are modifying information to properly display it, it should go into the view.

I doubt it should be in the model primarily because if the data was always going to be shortened, you would probably would store it shortened.
