Question

我有一个简单的表单，用户可以在其中编辑内容。如果用户进入编辑操作，则表单会预填充其知道的信息。但是，这仅适用于开发。在暂存和生产服务器上，这不起作用。如果用户填写编辑操作的空白字段，则会正常更新。

= form_for [@upload, @seller], :url => upload_seller_path(@upload, @seller) do |form|
  = render 'error_messages', :subject => form.object
  %h2 Edit information
  .form-group
    = form.label :first_name
    = form.text_field :first_name, class: 'form-control'
  .form-group
    = form.label :last_name
    = form.text_field :last_name, class: 'form-control'
  .form-group
    = form.label :address
    = form.text_field :address, class: 'form-control'
  .form-group
    = form.label :city
    = form.text_field :city, class: 'form-control'
  = form.submit class: 'btn btn-primary'
  = link_to 'Cancel', upload_seller_path(@upload), class:'btn btn-default'

控制器

class IncompleteSellersController < ApplicationController
  before_filter :set_upload
  before_filter :set_seller, except: [:index]

  def update
    if @seller.update(sellers_params)
      redirect_to upload_incomplete_sellers_path(@upload)
    else
      render :edit
    end
  end

  private
  def set_upload
    @upload = Upload.find(params[:upload_id])
  end

  def set_seller
    @seller = @upload.sellers.find(params[:id])
  end

  def sellers_params
    params.require(:seller).permit(:first_name, :last_name, :address, :city)
  end
end

我尝试添加value: @seller.address，但它无效。知道事情可能出错吗？

编辑操作在开发时填写表单，但不在登台或生产中填写
