I'm trying to make a cases manage system in Ruby on Rails. I have two tables: audit_cases and ra_cases. 'audit_cases' has the columns 'Audit_Charge_Code' (primary key) and 'Client_ID'. 'ra_cases' has the columns 'audit_case_id'(foreign key), 'RA_Charge_Code','RA_Manager','RA_IC','RA_Performer' etc.

I have already join the two tables

model:

 class RaCase < ActiveRecord::Base
 belongs_to :audit_case 
 end

 class AuditCase < ActiveRecord::Base
 self.primary_key = "Audit_Charge_Code"
 has_many :ra_cases 
 end

controller:

 def index
 @a_cases = AuditCase.includes(:ra_cases).all
 end

view:

 <% @a_cases.each do |a_case| %>
 <tr>
 <td><%= a_case.Client_ID %></td>
 <td><%= a_case.Audit_Charge_Code %></td>
 <td><%= a_case.ra_cases.each do |ra_case| %>
 <%= ra_case.RA_Charge_Code %> <%= ra_case.RA_Performer %><br>
 <% end %>
 </td>
 </tr>
 <% end %>

I expect the output will be:

 ClientID AuditChargeCode RAChargeCode
 PCC502 PCC5020218 PCC5027119
 PCC502 PCC5020218 PCC5027120
 PCC502 PCC5020218 PCC5027121

But the actual output is:

 ClientID AuditChargeCode RAChargeCode
 PCC502 PCC5020218 PCC5027119
 PCC5027120
 PCC5027121
 [#<RaCase id: 1, audit_case_id: "PCC5020218", RA_Charge_Code: "PCC5027119", RA_Manager: "7829", RA_IC: "7687", RA_Performer: "7572", case_type: "GITC", fee: 75000, created_at: "2019-03-21 13:57:03", updated_at: "2019-03-21 13:58:19">, #<RaCase id: 2, audit_case_id: "PCC5020218", RA_Charge_Code: "PCC5027119", RA_Manager: "7829", RA_IC: "7687", RA_Performer: "7572", case_type: "AP Control", fee: 35000, created_at: "2019-03-21 19:01:07", updated_at: "2019-03-21 19:45:08">, #<RaCase id: 3, audit_case_id: "PCC5020218", RA_Charge_Code: "PCC5027119", RA_Manager: "7829", RA_IC: "7687", RA_Performer: "7408", case_type: "GITC", fee: 75000, created_at: "2019-03-21 19:14:41", updated_at: "2019-03-21 19:45:47">]

I was wondering how could I NOT to print the whole data array [#<...>] as a result.

Thank you very much!!

The reason you are printing the entire data array is because you are using the <%= %> format. This format prints its results. You will need to use the <% %> format, which doesn't print its results:

<% ra_case.RA_Charge_Code %> <%= ra_case.RA_Performer %>
