Answer 1

Though it is a very old question, stil i was also looking for the answer, This is how to do it:

just add it after f.input :project :

f.button "New Project", formaction: "new_entry", class: "some_class"

Then using member_action :

member_action :new_entry, method: :patch do
    
end

Answer 2

inputs 'Details' do
  li do
    label "Project"

    span do
      "here is your project input field"
    end

    span do
      "here is your button"
    end
  end
end
