Rails activeadmin dropdown menu in new and editable forms

Question

I have a has_many belongs_to association. I registered a resource. I have shipment owned by customers.

But when I switch to the new submission form, select for customers from the drop-down menu, I get # <0X0000>

Why? How can i fix this?

I think this is because the Customers table does not have the "name" attribute, instead I have a company_name. How can I use company_name in the dropdown menu?

Answer 1

You do not have to override the to_s method , the active administrator can use the display_name method specifically for this case.

so you can add next to your model

def display_name company_name end 

Answer 2

One option is to override to_s

 def to_s company_name end 

Another variant:

 f.input :customer, :as => :select, :label_method => : company_name , :value_method => :id 

Answer 3

 f.input :customer, :label_method => :company_name 

Answer 4

define the "to_s" method in your client model. Something like that:

 def to_s company_name end
