def create
@patient = Patient.new(params[:patient])
if @patient.save
redirect_to new_patient_path
end
end
def edit
@patient = Patient.find(params[:id])
end
def update
@patient = Patient.find(params[:id])
if @patient.update_attributes(params[:patient])
redirect_to :action => 'show', :id => @patient
else
@patient = patient.find(:all)
render :action => 'edit'
end
end
def destroy

感谢您的帮助！
推荐答案
<%= link_to "Delete", patient_path(@patient), :confirm => "Are you sure?", :method => :delete %>
更新
application.js 应该是
application.js should be
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
不是
= require jquery
= require jquery_ujs
= require turbolinks
= require_tree .
