title: Sending Pdf via email in Rails
body: <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">

  <pre class="snippet-code-html lang-html prettyprint-override"><code>emp_ids = params[:employee_ids]</code></pre>

  <p>I am working on a project in rails where i have an Employee List page,This list is the List of Salaryslip of an employee.In that list i have applied checkboxes and at the bottom there is an Send button.I want that if i select multiple checkboxes,Email should be gone to all the employees including the pdf of salary slip.I am able to do this if i select checkbox the on clicking on submit all the salaryslip come for the employee who i have selected but in that pdf page i can't apply email functionality so i want it to be directly happen.I have used wicked pdf and actionmailer but i'm confused how may i send an array of multiple employees ids(like this i have written in my index page [employee_ids] and accessed it using params[:employee_ids] in controller) to Action Mailer for send email.</p>
