我正在研究一种方法,当用户按下"删除按钮" 问题是,当我点击该按钮时,我想要删除的包将从网站中删除,但是当我检查数据库时,我发现了该记录。
控制器:
def deletepackage(user_id,package_id)
@package=Packages.find(:all, :condition=>{:id => package_id},
:condition => {:sender_Id => user_id})
if (@package!=nil && req.receivedByCarrier==false)
@package.destroy
elsif (@package!=nil && req.receivedByCarrier==true)
@package.destroy
end
return;
end
def delete
deletepackage(1,1)
package.destroy
redirect_to(:action => 'show')
end
def show
@create_package=Packages.find(params[:id ])
end
Show.html.erb:
<%=form_for(:package,:url{:action=>'create_packages/delete',
:id=>@create_package.id})do |f| %>
<p>Are you sure you want to delete this package?</p>
<%= f.submit "Delete" %>
答案 0 :(得分:2)
<强> Show.html.erb:强>
<%= link_to 'Delete', controller: 'your_controller_name', action: 'destroy', id: @package.id, method: :delete %>
<强>控制器:强>
def show
@package = Packages.find(params[:id])
end
def destroy
Packages.find_by(id: params[:id], sender_Id: 1).destroy
redirect_to :index
end
你无法从destroy重定向到'show'动作,因为没有要显示的包(包被破坏)。

我认为,您需要学习一些rails教程,例如Michael Hartl's Tutorial。
