# 1. In your view file (e.g., app/views/your_controller/your_action.html.erb), find the form where the submit button is located.
# 2. Locate the submit button element and add the 'disabled' attribute to it.
<%= form_with model: @your_model do |form| %>
# ... other form fields ...
<%= form.submit 'Submit', disabled: true %>
<% end %>
# 3. Optionally, you can use a condition to enable or disable the submit button based on a certain condition.
<%= form_with model: @your_model do |form| %>
# ... other form fields ...
<%= form.submit 'Submit', disabled: @your_condition %>
<% end %>
# 4. In your controller action, set the value of @your_condition based on your business logic.
def your_action
# ... your controller logic ...
@your_condition = true # Set to true to disable the submit button, or false to enable it.
# ... more controller logic ...
