angularjs - Controller and model/service separation of logic -


i understand business logic belongs in model , application logic belongs in controller. please clarify business logic , not include , application logic , doesn't include. giving consideration things redirects, confirmation dialogs etc

e.g.

 /**          * removes product          * @param product          */         _this.remove = function(product){             if(confirm('are sure want remove "' + product.product_name + '"?')){                 var idx = _this.currentproductsordered.indexof(product);                 _this.currentproductsordered.splice(idx, 1);             }         };

or should have confirm dialog box in controller , call remove method?

"unfortunately, pragmatic answer is: 'it depends.'" mvc model not "all it's cracked-up be."

nevertheless, suggest can meaningfully divide problem along line: "'user interface' ... versus ... 'not'"

for instance: "the entire exchange gentle user, no matter is, , no matter sort of technical machinations might involved executing it," falls under auspices of "user interface == controller."

eventually, user commit action. "okay, user wants product go away. it."

now engaging model layer, , telling him, "be so!" instruction being given model layer is, @ point, "an imperative command."

(of course, model might reply: "no! refuse!" in case have go user interface.)

basically, see it, "controller == user interface," , "model == affecting data." but: "it's guideline." it's not set in stone.
