ruby on rails recover data in params with form tag

To recover data in params with the form tag in Ruby on Rails, follow these steps:

  1. In your view file, create a form using the form_tag method. This method generates an HTML form without the need for an associated model.
<%= form_tag("/your_action", method: "post") do %>
  <!-- form fields go here -->
<% end %>
  1. Inside the form, add input fields using the text_field_tag or select_tag methods. These methods generate HTML input fields for text or select options, respectively.
<%= form_tag("/your_action", method: "post") do %>
  <%= text_field_tag(:name) %>
  <%= select_tag(:gender, options_for_select(["Male", "Female"])) %>
<% end %>
  1. Submit the form by adding a submit button using the submit_tag method.
<%= form_tag("/your_action", method: "post") do %>
  <%= text_field_tag(:name) %>
  <%= select_tag(:gender, options_for_select(["Male", "Female"])) %>
  <%= submit_tag("Submit") %>
<% end %>
  1. In your controller, define the action that handles the form submission. This action will receive the form data in the params hash.
def your_action
  name = params[:name]
  gender = params[:gender]

  # Handle the form data here
end
  1. Use the data from the params hash to perform any desired actions, such as saving it to a database or processing it in some way.

Note: Make sure to replace /your_action with the actual URL or route that corresponds to the action in your application. Also, customize the form fields and actions as per your requirements.

Remember to include appropriate validation and security measures to protect against malicious input and ensure data integrity.
