I am trying to print the factory BBB_A.

I have two models

• aaa has_many bbbs
• bbb belong_to aaa

  aaas. Rb

    Define factory grades Factory: Do After AAA (Build). AAA | Aaa.bbbs & lt; & Lt; Build (: BBB_A) aaa.bbbs & lt; & Lt; Factory (at the end of the end of Bibibi_ B)   
    bbbs.rb   
    Factorigirkdifain Factory: BBB Factory: Bibibi_a and Factory: Bibibi_ B End End End End   
    aaa_spec.rb   
    require describe 'spec_helper' Aaa it "puts works" AAA = Faktrigrlksent (AAA) aaa.bbbs (: Bibibi_a) # this gives both Bibibi_a and Bibibi_bi AAA. The Shild_net Bi_anil and end   
    console output   
    BBB 1 BBB finished in 2 0.11593 seconds Example 1, 0 failure seeds 44359 With random   
    what do i want   
    1 example ended in 0.11 billion seconds, random failure with seed 4435 9   
   Why is it that both put BBB_A and BBB_b? How can I just print it bbb_a?   
   
   
   You have to replace what you have to do    Aaa.bbbs (: bbb_a) with   
    
    puts aaa.bbbs.first   aaa  and  
   or  
    puts aaa.bbbs [0]   
   and  BBB  model, Rail creates the basic example methods for you as  aa #bbb  and  BBB # aaa . This method accepts 0 or 1 arguments. If you pass an argument to this method as  true , then the query is removed on the database to obtain the relevant records. And if you argue this method as  false , it only raises the cached results of the query (the query provided was removed once for caching).  
   Therefore, when you do  
    puts aaa.bbbs (: bbb_a)   
   passed the value only Neither  true  or  false .
