我有一个 Rails 应用程序，它的模型有点棘手，如您所见。应用程序能够为给定用户创建任务。
我正在使用下面的控制器/表单。显然，当我为 sby 创建任务时，我必须填写 :executor 字段，因为默认情况下我将成为 :assigner 。一旦创建了任务，从我的角度来看，它将是一个 :signed_task 。 下面的表单非常适合 new/create 操作，并且使用正确的参数也能显示 edit.html.erb，但我收到错误（即使我尝试更改分配的任务而不是执行的任务）：“没有路线匹配 [ PATCH]“/users/1/tasks”“当涉及到更新操作时。
我不确定是我的表单还是控制器出了问题。如果我点击 $rake 路线，一切看起来都很好。
我有 2 个问题： 1. 如何使更新操作适用于 :signed_tasks，以便 :assigner 可以编辑他们分配给 sby 的任务？ 2. 这是一个更难的问题：我应该怎么做才能让 :executors 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"
用户型号：
has_many :assigned_tasks, class_name: "Task", foreign_key: "assigner_id"
has_many :executed_tasks, class_name: "Task", foreign_key: "executor_id"
新建和编辑表格：
<%= 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

我把它拉下来了。我仍然不明白为什么前一个不起作用，为什么这个起作用。我将它用于 user.profile。尽管该个人资料与用户是一对一的关系，但这是事实。
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| %>
