Rails/ spec fill_in using placeholder

Question

In my rspec test, how do I fill_in a text field using Placeholder. I cannot use id and name as they are auto generated for the nested form.

<input class="input-medium inline" id="user_kids_attributes_new_1342116887461_first_name" name="user[kids_attributes][new_1342116887461][first_name]" placeholder="First Name" size="30" type="text">

Thanks

Answer 1

There is also another way:

fill_in :placeholder => "Fill in some text", :with => "Text"

Answer 2

Placeholder support will be in the next version of Capybara. For now, try:

find("input[placeholder='First Name']").set "value"
