试图更新记录 - Rails

Question

我只是想更新assignment模式上的名称和说明。我似乎无法弄清楚我做错了什么？

这是我的代码：

控制器

 def edit
    @assignment = Assignment.find_by(id: params[:id])
  end

  def update
    @assignment = Assignment.find_by(id: params[:id])
    if @assignment.update_attributes(assignment_params)
      flash[:notice] = "Successfully Edited The Assignment"
      redirect_to account_assignments_path
    else
      render 'edit'
    end
  end

VIEW

<td><%= button_to "edit assignment", edit_account_assignment_path(assignment), method: :get %>

归于

 <%= form_for @assignment, url: account_assignments_path(@assignment) do |form| %>
  <%= form.label :name %>:
  <%= form.text_field :name %>

  <%= form.label :description %>
  <%= form.text_field :description %>

  <%= form.submit %>
<% end %>

规格

it "edits an assignment" do
  user = create(:user)
  account = create(:account, users: [user])
  assignment = create(:assignment, account_id: account.id)
  login_user(user)

  visit account_assignments_path
  click_button "edit assignment"

  expect(current_path).to eq(edit_account_assignment_path(assignment))

  fill_in :assignment_name, with: "Edited"
  fill_in :assignment_description, with: "Edited Too"
  click_button "Update Assignment"

  expect(current_path).to eq(account_assignments_path)
  expect(page).to have_content("Successfully Edited The Assignment")
end

错误：

Creating a assignment assignment management edits an assignment
 Failure/Error: click_button "Update Assignment"

 ActionController::RoutingError:
   No route matches [PATCH] "/account/assignments.1"

更改此行：

<%= form_for @assignment, url: account_assignments_path(@assignment) do |form| %> 

为：

<%= form_for @assignment, url: account_assignment_path(@assignment) do |form| %>
