ruby on rails - Should I use integer or string to declare this attribute? -


i'm building app ruby on rails mesure demographic variables. right now, have doubt how declare type of data 2 attributes of model (stats) belongs users model. attributes "genere" , "civil status". know elements string data if pretend make statistics info, would more convenient declare data integer?, say, nominative data in statistic number enough represent status or genere, ie. 1 -> femenin / 2 -> masculin.

i'll appreciate advice. time.

enums integer bitmasks way attributes there definite amount of choices , add/removing options developer level concern.

class person < applicationrecord   enum gender: [:undisclosed, :male, :female, :other] end

this store gender in integer column values 0-3. column faster scan , index string column.

it saves hassle of whitelisting acceptable string values , writing scopes based on value.

you can person.female scope.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
