ruby on rails - rake db:migrate:reset to dump schema -

-

hell, i'm following in hartl's ruby on rails tutorial , i'm on chapter 9 adding administrative control users.

i'm @ part says

reset database:

 $ bundle exec rake db:migrate:reset  $ bundle exec rake db:seed

last time followed (much earlier in tutorial), reset database instructed deleted me schema.rb. annoying.

attempted again, , yet again deleted database , erased schema.rb. surely not intended.

i'm having trouble figuring out should doing anymore. i'm getting kinds of errors database. errors pending migrations, no db:xxx command works, every command spits out long list of errors such as

/users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/migration.rb:994:in `execute_migration_in_transaction' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/migration.rb:956:in `block in migrate' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/migration.rb:952:in `each' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/migration.rb:952:in `migrate' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/migration.rb:820:in `up' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/migration.rb:798:in `migrate' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/tasks/database_tasks.rb:137:in `migrate' /users/ke0/.rvm/gems/ruby-2.2.0/gems/activerecord-4.2.0/lib/active_record/railties/databases.rake:44:in `block (2 levels) in <top (required)>' tasks: top => db:migrate

what 1 in such situation?

try verify following :-

  1. you have db username/password mentioned in database.yml
  2. you have db empty
  3. when run rake db:migrate,then schema.rb getting generated
  4. you have valid database.yml file

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
