我试图让我的simple_form在嵌套资源上工作,它是不合作的。
这些是我的模特:
location.rb
:
# == Schema Information
#
# Table name: locations
#
# id :integer not null, primary key
# name :string
# created_at :datetime not null
# updated_at :datetime not null
#
class Location < ApplicationRecord
has_many :inventory_items, inverse_of: :location
accepts_nested_attributes_for :inventory_items
end
inventory_item.rb
:
# == Schema Information
#
# Table name: inventory_items
#
# id :integer not null, primary key
# product_id :integer
# location_id :integer
# created_at :datetime not null
# updated_at :datetime not null
#
class InventoryItem < ApplicationRecord
belongs_to :product
belongs_to :location, inverse_of: :inventory_items
end
这些是我的routes.rb
:
resources :locations, shallow: true do
resources :inventory_items
end
在这条路上:app/views/inventory_items/_form.html.erb
,我有以下几点:
<%= simple_form_for [@location, @inventory_item] do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :product, collection: Product.all %>
<%= f.input :location, as: :hidden, value: @location %>
</div>
<div class="form-actions">
<%= f.button :submit, class: "btn btn-outline-primary" %>
</div>
<% end %>
在我的InventoryItemsController
中,我有这个:
# GET /inventory_items/new
def new
@location = Location.find(params[:location_id])
@inventory_item = InventoryItem.new
end
def create
@inventory_item = InventoryItem.new(inventory_item_params)
respond_to do |format|
if @inventory_item.save
format.html { redirect_to @inventory_item, notice: 'Inventory item was successfully created.' }
format.json { render :show, status: :created, location: @inventory_item }
else
format.html { render :new }
format.json { render json: @inventory_item.errors, status: :unprocessable_entity }
end
end
end
在我的InventoryItemsController
中我强大的参数看起来像这样:
def inventory_item_params
params.require(:inventory_item).permit(:product_id, :location_id)
end
这是我得到的错误:

我正在使用Rails 5.1和Simple Form 3.5.1。
编辑1
我尝试将_form.html.erb
部分更改为:
<%= simple_form_for @inventory_item do |f| %>
我仍然得到相同/类似的错误:

变化:app/views/inventory_items/_form.html.erb
<%= simple_form_for @inventory_item do |f| %>
似乎正确的答案就是将url:
选项添加到simple_form_for
辅助方法并将f.input
的名称更改为:product_id
。
所以我的_form.html.erb
的最终版本看起来像这样:
<%= simple_form_for @inventory_item, url: :location_inventory_items do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :product_id, collection: Product.all %>
<%= f.input :location_id, as: :hidden, value: @location %>
<%#= f.input_field :avatar, as: :hidden, value: @profile.cached_avatar_data, class: 'col-lg-4 form-control '%>
</div>
<div class="form-actions">
<%= f.button :submit, class: "btn btn-outline-primary" %>
</div>
<% end %>
