ruby-on-rails - ruby on rails 中没有条目保存到数据库中？

Question

我创建了一个名为 tenants 的表，其中包含以下列

class CreateTenants < ActiveRecord::Migration
  def change
    create_table :tenants do |t|
      t.text :company_name
      t.text :work_area
      t.text :second_pref
      t.text :third_pref
      t.integer :who_are_you
      t.integer :number_of_bedroom
      t.text :other_specs
      t.string :budget
      t.string :name
      t.string :email
      t.string :contact_number

      t.timestamps null: false
    end
  end
end

我正在按照以下表格将数据输入表格

        <%= form_for Tenant.new do |val| %>

                <%= val.label :company_name, "Company Name" %>
                <%= val.text_field :company_name, class: 'form-control' %>

                <%= val.label :work_area, "Work Area" %>
                <%= val.text_field :work_area, class: 'form-control' %>

                <%= val.label :second_pref, "Second Preference" %>
                <%= val.text_field :second_pref, class: 'form-control' %>

                <%= val.label :third_pref, "Third Preference" %>
                <%= val.text_field :third_pref, class: 'form-control' %>

                <%= val.label :who_are_you, "Are you Family/Bachelor?" %>
                <%= val.text_field :who_are_you, class: 'form-control' %>

                <%= val.label :number_of_bedroom, "Number of Bedroom" %>
                <%= val.text_field :number_of_bedroom, class: 'form-control' %>

                <%= val.label :other_specs, "Other Requirments" %>
                <%= val.text_field :other_specs, class: 'form-control' %>

                <%= val.label :budget, "Your Budget" %>
                <%= val.text_field :budget, class: 'form-control' %>

                <%= val.label :name, "Name" %>
                <%= val.text_field :name, class: 'form-control' %>

                <%= val.label :email, "Email" %>
                <%= val.text_field :email, class: 'form-control' %>

                <%= val.label :contact_number, "Contact Number" %>
                <%= val.text_field :contact_number, class: 'form-control' %>

                <%= val.submit "Submit", class: "btn btn-primary" %>

    <% end %>

当我填写所有必填项并单击提交时，我在 Rails 服务器日志中看到以下输出。

  },

}
Unpermitted parameter: budget
   (0.1ms)  begin transaction

谁能告诉我，为什么会这样？

您的 tenants_controller.rb 文件的强参数中似乎缺少 :budget。应该是这样的。

private

    def tenant_params
        params.require(:tenant).permit(:company_name, 
                                   :work_area, 
                                   :second_pref, 
                                   :third_pref, 
                                   :who_are_you, 
                                   :number_of_bedroom, 
                                   :other_specs,
                                   :budget,
                                   :name, 
                                   :email, 
                                   :contact_number)
    end
