我有一个有点棘手模型的rails应用程序，如你所见。应用程序可以为给定用户创建任务。
我正在使用下面的控制器/表格。显然，当我为sby创建任务时，我必须填写：executor字段，因为我将默认为：assigner。创建任务后，从我的角度来看，它将是：assigned_task。 下面的表单适用于new / create操作，edit.html.erb也会显示正确的参数，但我收到错误（即使我尝试更改assigned_task而不是execution_task）：“没有路由匹配[ PATCH]“/ users / 1 / tasks”“当谈到更新操作时。
我不确定这是我的表单还是控制器出错了。如果我点击$ rake路线，一切看起来都不错。
我有两个问题：1。如何使更新操作适用于：assigned_tasks，所以：assigner可以编辑他们分配给sby的任务吗？ 2.这是一个更难的问题：我该怎么做：执行者能够编辑他们分配给的任务（：executed_tasks）？
任务模型：
belongs_to :assigner, class_name: "User"
belongs_to :executor, class_name: "User"
用户模型：
has_many :assigned_tasks, class_name: "Task", foreign_key: "assigner_id"
has_many :executed_tasks, class_name: "Task", foreign_key: "executor_id"
新表格和编辑：
<%= form_for @task, url: user_tasks_path do |f| %>
控制器：
def new
@user = current_user
@task = Task.new
end
def create
@user = current_user
@task = Task.new(task_params)
if @task.save
flash[:success] = "Task saved!"
redirect_to user_tasks_path(current_user)
else
render action: :new
end
end
def edit
@user = current_user
@task = Task.find(params[:id])
end
def update
@user = current_user
@task = @user.task.find(params[:id])
if @task.update_attributes(task_params)
flash[:success] = "Task updated!"
redirect_to user_tasks_path(current_user)
else
render action: :edit
end
end
private
def task_params
params.require(:task).permit(:executor_id, :name, :content, :deadline).merge(assigner_id: current_user.id)
end

我把它拉了下来。我仍然不明白为什么前一个没有成功，为什么会这样。我用它来用于user.profile。虽然配置文件与用户处于一对一的关系，但确实如此。
控制器：
def edit
@user = current_user
@task = Task.find(params[:id])
end
def update
@user = current_user
@task = Task.find(params[:id])
if @task.update_attributes(task_params)
flash[:success] = "Task updated!"
redirect_to user_tasks_path(current_user)
else
render action: :edit
end
end
形式：
<%= form_for ([@user, @task]) do |f| %>
