mysql - Are polymorphic relationships bad practice? -


i'm using laravel , have run need have polymorphic relationships. seem solve need, being able store different data based on type, in nutshell.

however, i'm aware not able use constraints, foreign keys. , i've read around they're anti-pattern. wondering others think it, , if using them without issues.

otherwise, there alternative way accomplish polymorphic relationships provide, without using them? (using laravel)

polymorphic relations anti-pattern , breaks best practices principles per mjolnic comment.

having said this, never store json in blob or text column? wordpress not store data serialized in mysql?

in real-world, (outside of university), there many scenarios idea break rules. depending on specific use-case, may appropriate break them.

simple blog example. have posts, have pages. both need same table format. benefits gained polymorphic relations far outweigh effort put normalising , development , maintenance when splitting content posts , pages.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
