python - Django 1.7 Migrations hanging -

-

i have django migration trying apply. gets made fine (it's small, it's adding charfield 2 different models. when run actual migrate hangs (no failure, no success, sits).

through googling i've found other open connections can mess restarted db. db connect continuously running jobs , new queries sneak in right away. small, , last time tried restarting think able execute migrate before else. still nothing.

are there other known issues cause this?

at least in postgresql cannot modify tables (even if it's adding new columns) while there active transactions. easiest workaround to:

  • run migration script (which hang)
  • restart webserver/wsgi container

when restarting webserver open transactions aborted (assuming don't have background processes have transactions open), no transactions blocking table, migration finish.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
