Ruby on Rails - 在某些字段验证失败后丢失表单值

Question

我有一个表格

     <%= f.input :firstname, :label => "Forename", :input_html => { :placeholder => "Forename"} %>
     <%= f.input :surname, :label => "Surname", :input_html => { :placeholder => "Surname", :"data-

  <%= f.input :publiclyfundedteaching, :label => "Publicly funded teaching (PFT)", :input_html => {:style => 'width:7%', :id => "publiclyfundedteaching", :value => '0', :onkeyup => "myFunction()"} %>

  <%= f.input :non_publicly_funded_teaching, :label => "Non-Publicly Funded teaching (NPFT)", :input_html => {:style => 'width:7%', :id => "non_publicly_funded_teaching", :value => '0', :onkeyup => "myFunction()"} %>

和控制器

def create


@submission = Submission.new(submission_params)
@email = @submission.email
puts @email
if @submission.save
  flash[:notice] = 'Your user was successfully created.'
  
  else

@staffform = Form.find(10000)
   @livestatus = @staffform.status
   puts @staffform.status
   puts "not saved"

  puts @submission.errors.full_messages
render :new
  end

和型号：

validates :firstname, presence: true
validates :surname, presence: true
validates :email, presence: true


validates :total, numericality: { only_integer: true, equal_to: 100}


# First group

validates :publiclyfundedteaching, numericality: { only_integer: true }
validates :non_publicly_funded_teaching, numericality: { only_integer: true }
validates :support_for_teaching, numericality: { only_integer: true }

问题是 :publiclyfundedteaching、non_publicly_funded_teaching 和 support_for_teaching 的教学字段在验证后不保留这些值。电子邮件、姓氏和名字都可以。

请告诉我如何解决这个问题。 我猜这与这些字段的 value 属性有关？

非常感谢！！

Answer 1

在submission_params 你可能有类似的东西：

def submission_params
  params.require(:your_model_name).permit(:firstname, :surname, :email)
end

这会删除任何其他字段以保护它们免受客户端伪造的数据的影响

如果您希望字段可写 - 将其添加到允许

Answer 2

查看:publiclyfundedteaching 和:non_publicly_funded_teaching 的表单字段中的:value => '0' （您提到的第三个不在您的表单中）。 即使您重新加载以前填写的表格，他们也会将字段中的值设置为 0。您可以删除它或尝试添加这样的 if 语句（假设提交是模型）：

<%= f.input :publiclyfundedteaching, label: "Publicly funded teaching (PFT)", input_html: { style: 'width:7%', id: "publiclyfundedteaching", value: @submission.publiclyfundedteaching || 0, onkeyup: "myFunction()" } %>
