ActiveResource Post custom method calls in rails

In this article i am going to explain work around/fix for "wrong status line: "" issue while you are doing any activeresource stuff in rails.

What is the problem,why "wrong status line: "" while making resource calls on "post" verb?

Here is my code snippet where is the line making the problem.

1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

class FactoringCashReceipt < ActiveResource::Base   self.site = configatron.cync.factoring.url   self.element_name = "cash_receipts"   #self.prefix = "/borrowers/:borrower_id/"   self.headers['X-BACK-KEY'] = BACKGROUND_SECRET_KEY   def self.create_bulk_cash_receipts(batch,cash_receipts_objects)     response = post("do_bulk_insert",{cash_receipts: cash_receipts_objects.to_json})   end   #def self.by_borrower(borrower_id)   #  borrower_receivables = get("get_all_customers_by_borrower", {borrower_id: borrower_id})   #end   #   #def self.by_invoice_no_lookup(lookup_no)   #  customers = get("get_all_customers_by_borrower", {borrower_id: borrower_id})   #end   #   #def self.by_borrower_with_lookup(borrower_id,lookup_no)   #   #end   #   #def self.by_borrower_with_customer_with_lookup(borrower_id,customer_id,lookup_no)   #  receivable = find(:all, from: :get_particular_receivable, params: {borrower_id: borrower_id,customer_id: customer_id,receivable_no: lookup_no})   #end   #   #def self.get_corresponding_receivables(params)   #  receivables = find(:all, from: :get_corresponding_receivables, params: {borrower_id: params[:borrower_id],customer_id: params[:customer_id],receivable_no: params[:receivable_no]})   #end end

Problem on line no 8
response = post("do_bulk_insert",{cash_receipts: cash_receipts_objects.to_json})
The above line does not make a resource call to other engine. This line complaining that "URI is too long".
Now there is a question on your mind, what other options available to send large data on post call while activeresource. The answer is below

Proper Syntax  for post call is 

post(your_custom_method_name,options = {},body='')
so what mistake i did was, i passed all varibables inside the options which is passed as query parameter.

response = post("do_bulk_insert",{cash_receipts: cash_receipts_objects.to_json}) (Wrong Approach)
after modification the code should like this
Either
response = post("do_bulk_insert",{},{cash_receipts: cash_receipts_objects}.to_json) (Right Approach)
or
response = post("do_bulk_insert",nil,{cash_receipts: cash_receipts_objects}.to_json)
(Right Approach).

Hopefully now you can understand how post custom method calls on ActiveResource working and what common mistakes we do on that.
