linking to the product from the index in rails - ruby-on-rails

Question

When I save a PayerContract in the create form, it saves the PayerContract and creates a "success you have created PayerContract {X}" where {X} is the PayerContract name and redirects the user back to the index. I want to allow the user to click the {X} to go to the edit page for that PayerContract.
In my index page I have:
= link_to t('payer_contracts.edit'), edit_payer_contract_path())
I need to give the PayerContract.id to the edit_payer_contract_path function. So, it would look something like edit_payer_contract_path(330)
The warning message I have displayed in my controller is this:
def create
payer_contract_params = PayerContract.assign_params_to_payer_contract(params)
#payer_contract = PayerContract.new(payer_contract_params)
respond_to do |format|
begin
if #payer_contract.save
format.html { redirect_to payer_contracts_path, notice: t('common.successfully_created', entity: #payer_contract.description) }
end
end
end
end
I found out that when I do something like:
edit_payer_contract_path(PayerContract.find()) it returns all the PayerContract that looks like: expected an attributes Hash, got [{"id"=>224, "name" ="hello", "id"=> 332, "name" = "hello2", "id"=>555, "name" = "sup" }] etc.
How can I correctly link the user to the PayerContract they just created?

Answer 1

you can have it two ways. Either pass parameter along your redirect_to method. obviously, pass the id of newly created PayerContract. This way you will have the id in params and you can use it in your link_to method.
If you don't want to pass the parameter, try storing the newly created PayerContract in session after successfully creating PayerContract. This way after redirect you will still have access to the saved value from the session
something like below
def create
#foo = Foo.new(foo_params)
if foo.save
session[:foo_id] = #foo.id
redirect_to foo_path
end
end

Answer 2

As beniutek said you can pass parameter in redirect_to. But when user first visit index page id is not defined so you can check in view if it is define set the id to link_to as below.
def create
payer_contract_params = PayerContract.assign_params_to_payer_contract(params)
#payer_contract = PayerContract.new(payer_contract_params)
respond_to do |format|
begin
if #payer_contract.save
format.html { redirect_to payer_contracts_path(id: #payer_contract.id), notice: t('common.successfully_created', entity: #payer_contract.description) }
end
end
end
end
In view
if params[:id].present?
= link_to t('payer_contracts.edit'), edit_payer_contract_path(params[:id].to_i))
