How to check a checkbox in capybara?

I found the following worked for me:

# Check
find(:css, "#cityID[value='62']").set(true)

# Uncheck
find(:css, "#cityID[value='62']").set(false)

It's better not to create multiple elements with the same id, so that (and not only for that) you can easily check/uncheck a checkbox with elegant

check 'cityID'
uncheck 'cityID'

If one can not avoid multiple elements with the same id and still needs to check a checkbox with certain value, he can do so with

find(:css, "#cityID[value='62']").set(true)
find(:css, "#cityID[value='62']").set(false)

I think you may have to give unique ids to your form elements, first of all.

But with regards to Capybara and checkboxes, the Capybara::Node::Actions#check instance method will allow you to find and check a checkbox by name, id, or label text.

When running capybara test, you got the page object. This you can use to check/uncheck any checkboxes. As @buruzaemon already mentioned:

to find and check a checkbox by name, id, or label text.

So lets assume you got a checkbox in your html like:

<label>  
  <input type="checkbox" value="myvalue" name="myname" id="myid">
  MyLabel
</label>

You could check this with:

page.check('myid')
page.check('MyLabel')
page.check('myname')

Uncheck is the same just use page.uncheck method.
