[英]Rails simple_form object_id association
在我的应用程序中,我有很多模型:(产品归属者到创建者,创作者属者到comagnie,公司归属者belongs_to SEO,搜索引擎优化belongs_to用户)
在我的第一个Seoscontroller中,我知道:
def create
@seo = current_user.seos.build(seo_params)
if @seo.save
redirect_to search_path
else
render :new
end
end
(找到控制器工作!)
我认为在Compagniescontroller中(但不起作用:[]
def create
seo = Seo.find(params[:seo_id])
@compagnie = seo.compagnies.build(compagnie_params)
if @compagnie.save
redirect_to search_path
else
render :new
end
end
并以我的simple_form ....
<%= simple_form_for @compagnie(seo_id: seo.id) do |f| %>
<% end %>
我搜索一个解决方案以将我的模型ID关联到控制器和simple_form_for
(我的rails错误:在/ compagnies / new关联处找不到RuntimeError:seo_id)
编辑
create_table "seos", force: :cascade do |t|
t.string "name"
t.string "surname"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "user_id"
t.index ["user_id"], name: "index_seos_on_user_id", using: :btree
end
create_table "compagnies", force: :cascade do |t|
t.string "compagnie_name"
t.string "address"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "seo_id"
t.integer "user_id"
t.index ["seo_id"], name: "index_compagnies_on_seo_id", using: :btree
t.index ["user_id"], name: "index_compagnies_on_user_id", using: :btree
end
用户模型
class User < ApplicationRecord
has_many :seos
has_many :compagnies
end
徐模型
class Seo < ApplicationRecord
belongs_to :user
has_many :compagnies
validates :name, presence: true
validates :surname, presence: true
end
公司模型
class Compagnie < ApplicationRecord
belongs_to :user
belongs_to :seo
validates :address, presence: true
validates :compagnie_name, presence: true
end
徐的表格
<%= simple_form_for @seo do |f| %>
<div class="search__form--left split-panel--left">
<div class="search__title">
Seo:
</div>
<div class="search__section search__section--od">
<!--Name-->
<div class="search__field search__departure grouped-input--top">
<%= f.input :name, placeholder: "name", :input_html => { :class => "add__name-input ember-text-field textfield station-text-field empty station-text-field-- add__input empty" }, label: false %>
</div>
<!--Surname-->
<div class="search__field search__arrival grouped-input--bottom">
<%= f.input :surname, placeholder: "prenom", :input_html => { :class => "add__name-input ember-text-field textfield station-text-field empty station-text-field-- search__input empty" }, label: false %>
</div>
</div>
<!--Button-->
<div class="search__button progress-button">
<%= f.button :submit, "Add", class: "button progress-button--button" %>
</div>
</div>
<% end %>
公司表格
<%= simple_form_for @compagnie(seo_id: seo.id) do |f| %>
<div class="search__form--left split-panel--left">

</div>
</div>
<!--Button-->
<div class="search__button progress-button">
<%= f.button :submit, "Add", class: "button progress-button--button" %>
</div>
</div>
<% end %>
谢谢
我认为这应该在这行引发语法错误
<%= simple_form_for @compagnie(seo_id: seo.id) do |f| %>
但不知何故。 如果要将seo.id
传递给表单url,则必须将其放在:url
参数中。 Rails FormHelper
使用polymorphic_url生成表单操作url。 看看它的文档,您会发现为什么您的代码不起作用。 就您而言,如果您的路由文件如下所示:
resources :compagnies
那么表格应该是
<%= simple_form_for @compagnie, url: compagnies_path(seo_id: seo.id) do |f| %>
如果您的路线是这样的(推荐)
resources :seos do
resources :compagnies
end
那么表格应该是
<%= simple_form_for [@seo, @compagnie] do |f| %>
希望能有所帮助。
