Capybara does not check checkboxes

For my integration test, I want to check some checkboxes in a form.

But for some reason, Capybara doesn’t check the checkboxes. When I use ‘save_and_open_page’ to view the page in the browser while testing, the checkboxes are not checked.

my form looks like this:

<%= form_for [:admin, @research_project] do |f| %>
    <%= f.label :title %>
    <%= f.text_field :title %>
    <%= f.label :body %>
    <%= f.text_area :body %>
     <%= f.collection_check_boxes :research_theme_ids, ResearchTheme.all, :id, :title %>
  <%= f.submit "Add Research Project" %>
<% end %>

The rendered html looks like this:

<form accept-charset="UTF-8" action="/admin/research_projects" class="new_research_project" id="new_research_project" method="post"><div style="display:none"><input name="utf8" type="hidden" value="&#x2713;" /></div>
    <label for="research_project_title">Title</label>
    <input id="research_project_title" name="research_project[title]" type="text" />
    <label for="research_project_body">Body</label>
    <textarea id="research_project_body" name="research_project[body]">
     <input id="research_project_research_theme_ids_1"     name="research_project[research_theme_ids][]" type="checkbox" value="1" /><label      for="research_project_research_theme_ids_1">voluptas rem consectetur aut quas</label><input    id="research_project_research_theme_ids_2" name="research_project[research_theme_ids][]"     type="checkbox" value="2" /><label for="research_project_research_theme_ids_2">et non architecto voluptatem aliquam</label><input id="research_project_research_theme_ids_3" name="research_project[research_theme_ids][]" type="checkbox" value="3" /><label for="research_project_research_theme_ids_3">ab consequatur quia ducimus et</label><input name="research_project[research_theme_ids][]" type="hidden" value="" />
  <input name="commit" type="submit" value="Add Research Project" />

My integration test looks like this:

scenario "Admin adds research themes to research project" do
research_theme_1 = Fabricate(:research_theme)
research_theme_2 = Fabricate(:research_theme)
research_theme_3 = Fabricate(:research_theme)

click_link "Add Research Project"

expect(page).to have_css 'label', text: research_theme_1.title
expect(page).to have_css 'label', text: research_theme_2.title
expect(page).to have_css 'label', text: research_theme_3.title


click_button "Add Research Project"

expect(@research_project.research_themes.count).to eq(2)


I’m using Rails 4.1.0 and Capybara 2.3.0

Does anyone know how to solve this problem?

thanks for your help,


Capybara doesn’t say it doesn’t find the checkboxes, it just doesn’t check them, so I wonder if this is a bug in Capybara 2.3.0, or if Capybara doesn’t play well Rails 4 collection_check_boxes

my repo is at:

the test is in:

the failing scenario is called: “Admin adds research themes to research project”

thanks for your help,
