[英]passing parameters using link_to in haml
%tbody
- @accounts.each do |account|
%tr
%td= link_to account['id'],show_path,{:id => account['id']}
%td= account['name']
%td= account['description']
%td= account['created']
以上只是haml文件的一個片段,在我的控制器中我有以下內容:
def show
# If a system account already exists in session, it was found from a search with the account id
# Otherwise, this is a new search for a system account by the given id
@account = session[:account]
if @account.nil?
Rails.logger.debug { "Querying for the account with id: #{params[:id]}" }
response = query_account(CGI.escape(params[:id]))
@account = JSON.parse(response.body)
end
end
路徑(show_path)是/ system_accounts /:id
如果id為23,我如何將參數id傳遞給控制器和link / system_accounts / 23,例如:。
這將鏈接到該帳戶的正確顯示頁面:
= link_to account.id, account
您始終可以向路徑顯式添加任何其他參數:
= link_to account.id, account_path(:id => account.id, :foo => "bar")
