Hello,

I am testing how to use the external api. Here is my code in golang.
I wanted to upload a file to purchase order and create a rest api from that. However, when I tested this, there was no error. But I can't seem to find any attachments on purchase order. I also don't seem to see an attachment_ids field. But no error was generated so I am getting confused. 

By any chance, can someone help me and point me to the right direction on how to upload a file to a purchase order through the api? and then display that at least?

Thank you!

// Base64 encode the file data    
fileB64 := base64.StdEncoding.EncodeToString(fileData)

models, err := xmlrpc.NewClient(fmt.Sprintf("%s/xmlrpc/2/object", url), nil)    
if err != nil {        
log.Fatal(err)    
}    

var id int64    
if err := models.Call("execute_kw", 
      []interface{}{        
          db, uid, password,        
          "ir.attachment", "create",        
          []interface{}{
              map[string]interface{}{                
                 "res_model": "purchase.order",                
                 "name":      "Vendor Invoice",

                 "type":      "binary",                
                 "datas":     fileB64,            
               },        
           },    
     }, &id); err != nil {
         log.Fatal(err)    
     }
