python - Django ManyToMany Relation with django.contrib.auth.models.User -


i have following model:

class bm(models.model):     created_date = models.datetimefield(auto_now_add=true, editable=false)     birth_date = models.datetimefield(null=false, blank=false)     name = models.charfield(null=false, blank=false, max_length = 255)     relations = models.manytomanyfield(user)

when try run test python manage.py test following error:

django.db.utils.programmingerror: relation "auth_user" not exist

this due trying create relation user table before table gets created itself.

how can this?

edited say:

this happening because bm model table being created before auth user table, following statement run (according ./manage sqlall p:

create table "p_baby_relations" (     "id" serial not null primary key,     "baby_id" integer not null,     "user_id" integer not null references "auth_user" ("id") deferrable deferred,     unique ("baby_id", "user_id") ) ;

the error because of not null references "auth_user" means auth user table has not been created.

you need specify auth.user dependency in migration.

class migration(migrations.migration):     dependencies = [         ('user', '0001_initial'),     ]

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

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...
