How to fill hidden field with Capybara?

Question

I\'ve already found that when I want to set value to text field, text area or password field, I can use id, name or label as something in fill_in somethin

Answer 1

You need to locate the hidden field and set its value. There are a couple ways, this is probably the simplest

find(:xpath, "//input[@id='my_hidden_field_id']").set "my value"

If you're executing a client_side script in production, you could just tell capybara to run it with a javascript-compliant driver

page.execute_script("$('hidden_field_id').my_function()")
