在房產視圖中添加租戶用戶

Question

我試圖在房產＃顯示視圖內添加租戶用戶。我有一個表格有類似如下：

<%= form_for(@property.tenants) do |f| %> 
    <div class="field"> 
    <%= f.label :name %><br /> 
    <%= f.text_field :name %> 
    </div> 
    <div class="field"> 
    <%= f.label :email %><br /> 
    <%= f.text_field :email %> 
    </div> 
    <div class="select"> 
    <%= f.select :type, [['Landlord'],['Tenant']] %> 
    </div> 
    <%= f.submit "Add", %> 
<% end %> 

租客模型如下：

class Tenant < User 
    belongs_to :property 
    def type 
    "Tenant" 
    end 
end 

和屬性模型如下：

class Property < ActiveRecord::Base 
    attr_accessible :address, :bathrooms, :bedrooms, :postcode, :price 
    belongs_to :branch 
    belongs_to :user 

    has_many :ownerships 
    has_many :landlords, :through => :ownerships 

    has_many :tenants 
end 

當我點擊添加按鈕我神奇地重定向到根路徑（/）。 我期待它爲我在show view中查看的特定屬性添加新租戶，但它只是將我重定向到根路徑。

隨意問任何澄清 結果耙路線：

Answer 1

我覺得有幾件事情，似乎並不完全正確。

試試這個。

將@tenant實例變量添加到Properties控制器的show方法中。

def show 
    ... 
    @tenant = @property.tenants.build 
end 

並修改form_for行爲此。

<%= form_for @tenant do |f| %> 

Answer 2

在你properties_controller.rb，

def show 
@tenant = Tenant.new 
end 

你再從應該是：

<%= form_for @tenant do |f| %> 

您還應該添加一個隱藏字段屬性的ID，因爲當你提交表單。

然後爲您創建行動properties_controller.rb

def create 
    tenant = Tenant.new(params[:tenant]) 
    tenant.property_id = params[:property_id] #This is from that hidden field with your property_id and this also assumes you have a column in your tenant table for property_id 
    tenant.save 

    #the shorter way would just be tenant = Tenate.create(params[tenant]) but I want to emphasize the property_id since this attribute is paramount to your property-tenant relationship 
end 

這將有效地創建一個表單新房客，當你創建實際的承租人記錄，你會救樓市ID與新承租人記錄。

在另一個說明中，我建議將此按照Rails約定移至租戶控制器，並在新操作下創建表單，因爲您確實正在創建新的租戶記錄。
