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:
- 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 %>
- Inside the form, add input fields using the
text_field_tag
orselect_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 %>
- 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 %>
- 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
- 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.
