我在你的路线上没有看到任何“汽车消费”
我在你的路线上看不到任何“汽车消费”。试试这个:
<%= form_for [@cars, @consumptions] do |form| %>
...
<% end %>
形成:
<% = simple_form_for [@car, @consumption] do |f| %>
试试这个:
<%= form_for [@cars, @consumptions] do |form| %>
...
<% end %>
形成:
<% = simple_form_for [@car, @consumption] do |f| %>
您没有显示新的
操作,但我假设您正在设置@car
和@consumption=@car.consumpions.build
变量
试试这个:
simple_form_for @consumption, url: url_for(controller: :consumptions, action: :create, car_id: @car.id) do |f|
它应该与[@car,@consumpion]do | f |
的simple_form_一起工作,但是你说的“它不工作”太模糊了(怎么不工作?相同的错误?新的错误?你在回答问题时应该更清楚)你没有显示你的新的动作,但是我假设您正在设置一个@car
和一个@consumpion=@car.consumpions.build
变量
试试这个:
simple_form_for @consumption, url: url_for(controller: :consumptions, action: :create, car_id: @car.id) do |f|
它应该与[@car,@consumpion]do | f
的简单表单一起工作,但是你说的“它不工作”太模糊了(这怎么不工作?相同的错误?新的错误?你在回答问题时应该更清楚)让我们从控制器开始
# GET /cars/:car_id/consumptions/new
def new
@car = Car.find(params[:car_id])
@consumption = @car.consumptions.new
end
# POST /cars/:car_id/consumptions
def create
@car = Car.find(params[:car_id])
@consumption = @car.consumptions.new(consumption_params)
# `.save!` will raise an exception and blow up if the record is invalid.
# Not good.
if @consumption.save
redirect_to car_consumptions_path(@car), notice: 'consumption was successfully created.'
else
render :new
end
end
注意重定向:
# consumptions#index
redirect_to car_consumptions_path(@car), notice: 'consumption was successfully created.'
由于这是一条嵌套路线,您需要提供car\u id
段
您还可以重定向到:
# consumptions#show
redirect_to [@car, @consumption], notice: 'consumption was successfully created.'
# or to cars#show
redirect_to @car, notice: 'consumption was successfully created.'
当对
使用simple\u form\u时,您会将表单绑定到的模型实例传递给它。为嵌套管线创建表单时,应传递一个数组:
<%= simple_form_for([@car, @consumption]) do |f| %>
<% end %>
这将使用来查找正确的路径。您可以将此签名用于链接到,重定向到,url和路径
当声明嵌套路由时,应该考虑。它将只嵌套收集路由(新建、创建、索引),而不嵌套成员路由。
