Debug models with the rails console -

-

not sure why happening:

2.0.0p247 :001 > user.column_names  => ["id", "user_name", "email", "password_digest", "created_at", "updated_at", "register_key", "culminated", "remember_token", "register_token_created_at", "profile_image", "licence_image", "first_name", "last_name", "nearest_town"]  2.0.0p247 :002 > user1 = user.create(user_name: 'james', email: 'james@killbots.com', first_name:'jj', last_name:'jj', nearest_town:'mordor')  => #<user id: nil, user_name: "james", email: "james@killbots.com", password_digest: nil, created_at: nil, updated_at: nil, register_key: nil, culminated: nil, remember_token: nil, register_token_created_at: nil, profile_image: nil, licence_image: nil, first_name: "jj", last_name: "jj", nearest_town: "mordor">  2.0.0p247 :003 > user1.update(user_name: 'killo')  => false

rather solution, how go debugging problem console?

your user record not saved, because of failed validation. should check validity with: 

user1.valid?

and show errors:

user1.errors.full_messages

-
i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).
