Rspec，Rails 5，Ransack：测试视图index.html.erb

Question

我有错误 ActionView :: Template :: Error：没有Ransack :: Search对象已提供给search_form_for！ 我尝试使用源代码

it "displays all the users" do
assign(:users, [
  FactoryBot.create(:user, name: "slicer"),
  FactoryBot.create(:user, name: "dicer")
])

render

expect(rendered).to match /slicer/
expect(rendered).to match /dicer/

结束

我在控制器的方法索引中使用了rasack

def index
@q = User.ransack params[:q]
@users = @q.result.newest._page params[:page]
respond_to do |format|
  format.html
  format.xls{send_data @users.to_xsl}
end

结束 这就是我的观点

<div class="input-group search_inline">
  <%= search_form_for @q do |f| %>
    <%= f.label :user %>
    <%= f.search_field :user_cont, placeholder: t(".search") %>
    <%= f.submit t(".search"), name: nil, class: "btn btn-primary 
      btn_search" %>
  <% end %>
</div>

请帮助我！
