symfony - Symfony2 Doctrine use wrong alias in SQL, login fails with "Authentication request could not be processed [...]" -


i trying make own user bundle, , struggling @ login phase, error message :

authentication request not processed due system problem.

i'm kinda new symfony , doing best learn many aspects possible, please forgive me if took wrong path in defining stuff.

structure

i have 2 bundles, 1 app called scoreboardbundle, , 1 dedicated authenticating mechanic called pulsahr\userbundle. intend make bundle reusable in of projects.
user entity want use scoreboardbundle\entity\user, , inherits pulsahr\userbundle\entity\user, implements userinterface, \serializable.

log info

i looked dev.log, , found intriguing line :
[2016-09-22 14:16:19] security.info: authentication request failed. {"exception":"[object] (symfony\component\security\core\exception\authenticationserviceexception(code: 0): exception occurred while executing 'select t1.id id_2, t1.username username_3, t1.password password_4, t1.roles roles_5, t1.email email_6, t1.config config_7, t1.name name_8, t1.avatar avatar_9, t1.graph_color graph_color_10 from user t1 t0.username = ? limit 1' params [\"fdsfgsd\"]

i made mistake somewhere, doctrine looking t0.username without defining t0 alias. why ?

below several of files, hope help.

i had manually enter user, , used bcrypt calculator password, using 4 cost, same defined in security.yml. whatever login , password used, have same error message.

after many struggles, friend helped me find solution.
problem caused inheritance on scoreboardbundle\user\entity\user pulsahr\userbundle\entity\user.
php classes fine, problem comes mapping. had specify in user.orm.yaml origin class type "mappedsuperclass". doing this: 

pulsahr\userbundle\entity\user: type: mappedsuperclass table: user [...]

more info on doctrine documentation : http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/inheritance-mapping.html
hope people stuck me.

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

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
