ruby - Rails - SQLite, table error -


im new in rails , have project school. did :

bundle exec rails g migration addtypetocarte type:belongs_to

but have error when did migration (rake db:migrate)

this class addtypetocarte

class addtypetocarte < activerecord::migration   def change     add_reference :cartes, :type, index: true, foreign_key: true   end end

my error in terminal :

sqlite3::sqlexception: no such table: cartes: alter table "cartes" add "type_id" integer/users/pierresisson/documents/hearthdex/db/migrate/20150515075035_add_type_to_carte.rb:3:in `change' activerecord::statementinvalid: sqlite3::sqlexception: no such table: cartes: alter table "cartes" add "type_id" integer /users/pierresisson/documents/hearthdex/db/migrate/20150515075035_add_type_to_carte.rb:3:in `change' sqlite3::sqlexception: no such table: cartes /users/pierresisson/documents/hearthdex/db/migrate/20150515075035_add_type_to_carte.rb:3:in `change'

i tried add type_id doesnt work. think have no table named "cartes" :/ need please, !

first create model named carte (rails g model carte) run rails generate migration addtypereftocarte type:references.

also in carte model file add belongs_to :type. can read more associations here.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
