我有一个使用浅层资源嵌套的Rails 5应用程序。 form_for已停止工作，我找不到原因。
该应用程序具有多个嵌套模型，这些模型在根据我先前发现的问题here的建议更改为浅层路线之前可以工作
我的架构如下：
db / schema.rb：
create_table "as1851_tests", force: :cascade do |t|
t.bigint "damper_id"
t.boolean "AS1851A", default: false, null: false
t.boolean "AS1851B", default: false, null: false
t.boolean "AS1851C", default: false, null: false
t.boolean "AS1851D", default: false, null: false
t.boolean "AS1851E", default: false, null: false
t.boolean "Pass", default: false, null: false
t.string "comment"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.index ["damper_id"], name: "index_as1851_tests_on_damper_id"
end
create_table "dampers", force: :cascade do |t|
t.string "location"
t.string "number"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.bigint "site_id"
t.index ["site_id"], name: "index_dampers_on_site_id"
end

我得到的错误是
NoMethodError in As1851Tests#new
Showing /Users/jeremybray/RubymineProjects/ComplianceManagerv2/app/views/as1851_tests/_form.html.erb where line #1 raised:
undefined method `as1851_tests_path' for #<#<Class:0x00007fe0c7c820a8>:0x00007fe0c8325248>
Did you mean? as1851_test_path
as1851_test_url
对此的任何帮助将不胜感激，因为整条浅层路线对我来说都是新的。

在我看来，这些路线似乎是由浅水区操纵为单数的：true
答案 0 :(得分：1)
这让我难过了一段时间，但是使用在this question中找到的线索，我意识到ID不再由路线或before_action设置，所以我必须这样规定：
控制器
app / controllers / as1851_tests_controller.rb
nullapp / controllers / dampers_controller.rb
# GET /as1851_tests/new
def new
@damper = Damper.find(params[:damper_id])
@as1851_test = As1851Test.new
end
# GET /as1851_tests/1/edit
def edit
end
# POST /as1851_tests
# POST /as1851_tests.json
def create
@damper = Damper.find(params[:damper_id])
@as1851_test = As1851Test.new(as1851_test_params)
@as1851_test.damper = @damper
respond_to do |format|
if @as1851_test.save
format.html { redirect_to @damper.site, notice: 'As1851 test was successfully created.' }
format.json { render :show, status: :created, location: @damper.site }
else
format.html { render :new }
format.json { render json: @damper.site, status: :unprocessable_entity }
end
end
end
真的很基本的东西
