我创建了一个包含的valuation
表
class CreateValuations < ActiveRecord::Migration
def change
create_table :valuations do |t|
t.text :location
t.integer :number_of_bedroom
t.integer :number_of_bath
t.integer :age_of_building
t.text :other_details
t.string :name
t.string :email
t.integer :contact_number
t.timestamps null: false
end
end
结束
后来,我使用rails generate migration add_building_to_valuations building:text
在其中添加了文本类型的列:building
。我已经创建了一个表单
<div class="row">
<div class="col-md-6 col-md-offset-3">
<%= form_for(@valuation) do |val| %>
<%= val.label :building, "Name of Building/Builder" %>
<%= val.text_field :building, class: 'form-control' %>
<%= val.label :location, "Location" %>
<%= val.text_field :location, class: 'form-control' %>
<%= val.label :number_of_bedroom, "Number of Bedroom" %>
<%= val.text_field :number_of_bedroom, class: 'form-control' %>
<%= val.label :number_of_washroom, "Number of Washroom" %>
<%= val.text_field :number_of_bath, class: 'form-control' %>
<%= val.label :age_of_building, "Age of Building" %>
<%= val.text_field :age_of_building, 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 "Evaluate my property", class: "btn btn-primary" %>
<% end %>
</div>
</div>
当我填写所有字段并通过Evaluate my property
提交时,则:building
中没有保存任何数据。
我使用以下命令对此进行了检查$ rails console
$ Valuation.all
和接收的输出跟随输出
#<Valuation id: 1, location: "Chandivali, Powai",
number_of_bedroom: 3, number_of_bath: 3,
age_of_building: 9, other_details: nil, name: "Shravan",
email: "shravan.xxx@gmail.com",
contact_number: "9876543210",created_at: "2015-11-14 09:47:26",
updated_at: "2015-11-14 09:47:26", building: nil>,
您应该更新您的valuation_params
,这很可能是一个私有函数
private
def valuation_params
params.require(:valuation).permit(:building,
:location,
:number_of_bedroom,
:number_of_bath,
:age_of_building,
:name, :email, :contact_number)
end
end
