How to set text into Summernote textarea with Capy

I have a textarea which is using Summernote and I set onChange event to it. I want to write test with RSpec + Capybara + Poltergeist to confirm the onChange event is working.

As far as I checked, the textarea displayed in browser is actually div tag with 'note-editable' css class. How can I set text to it and fire onChange event?

I wrote a code like this, but got an error Capybara::ElementNotFound: Unable to find field "Some label":

visit edit_foo_path
fill_in 'Some label', with: 'Foo bar'

EDIT

I created a sample app for this issue:

回答1:

Capybaras fill_in only works with html form elements. Since the JS version of your page is using a DIV with the contenteditable attribute as its text area to be filled #fill_in will not work. Instead you need to find the div and call #set on it directly. In your project the following should work

find('div[contenteditable]').set('This is awesome blog.')

回答2:

After updating Summernote to 0.8.2, find('div[contenteditable]').set('This is awesome blog.') does not work.

I had to call Summernote API via execute_script like:

script = <<-JS
$('.some-field').summernote('editor.insertText', 'This is awesome blog.');
JS
execute_script(script)

EDIT

After updating Summernote to 0.8.2, find('div[contenteditable]').set('This is awesome blog.') does not work.

Sorry, this was not what I wanted to say. I should have said like this:

After updating Summernote to 0.8.2, find('div[contenteditable]').set('This is awesome blog.') does not fire Summernotes's onChange callback. So I had to call execute_script.

I have to test onChange behavior in my specs.

EDIT 2

As Thomas Walpole wrote, send_keys method could be used instead of execute_script. Thanks Thomas Walpole!

find('div[contenteditable]').send_keys('This is awesome blog.')
