创建新项目时如何从票证控制器设置枚举

Question

我的目标是在加载页面时在票证上设置类别、状态和严重性（所有枚举都在票证模型上定义）。 正在加载的页面是 cable_new_1。 问题是提交表单时没有设置类别、状态或严重性。

这是完整的门票控制器

 class TicketsController < ApplicationController
  before_filter :authenticate
  before_action :set_ticket, only: [:show, :edit, :update, :destroy, :close]

  # GET /tickets
  # GET /tickets.json
  def index
    @tickets = @customer.tickets.opened
    @tickets_closed = @customer.tickets.closed
  end

  def closed
    @tickets = @customer.tickets.is_closed
  end


  # GET /tickets/1
  # GET /tickets/1.json
  def show
  end

  def step_1
  end

  def billing_new_1
    @ticket = Ticket.new(severity: 'low', category: 'billing', summary: 'I am having a billing issue')
    render 'new'
  end

  def billing_edit
  end

  def internet_step_1
  end

  def internet_step_2
  end

  def internet_step_3
  end

  def internet_new_1
    @ticket = Ticket.new(severity: 'medium', category: 'internet', summary: "My internet is down, but my tv is working")
    render 'new'
  end

  def internet_new_2
    @ticket = Ticket.new(severity: 'medium', category: 'internet_and_cable', summary: "My internet and TV are both not working")
    render 'new'
  end

  def internet_new_3
      @ticket = Ticket.new(severity: 'low', category: 'internet', summary: "My internet is working, but is having some problem")
      render 'new'
  end

  def cable_step_1
  end

  def cable_step_2
  end


  def cable_new_1
    @ticket = Ticket.new(severity: 'medium', category: 'cable', summary: "My cable is down, but my internet is working")
  render 'new'
  end

  def cable_new_2
    @ticket = Ticket.new(severity: 'medium', category: 'internet_and_cable', summary: "My cable and internet are both not working")
    render 'new'
  end

  def cable_new_3
    @ticket = Ticket.new(severity: 'low', category: "cable", summary: "My cable has an issue")
    render 'new'
  end

  # GET /tickets/1/edit
  def edit
  end

  # POST /tickets
  # POST /tickets.json
  def create
    @ticket = Ticket.new(ticket_params)
    @ticket.opened!
    @ticket.customer_id = @customer.id
    @ticket.neighborhood_id = @customer.neighborhood_id
    respond_to do |format|
      @ticket.save!
      format.html { redirect_to tickets_path, notice: 'Ticket was successfully created.' }
    end
  end

  # PATCH/PUT /tickets/1
  # PATCH/PUT /tickets/1.json
  def update
    respond_to do |format|
      if @ticket.update(ticket_params)
        format.html { redirect_to @ticket, notice: 'Ticket was successfully updated.' }
      else
        format.html { render :edit }
      end
    end
  end

  # DELETE /tickets/1
  # DELETE /tickets/1.json
  def destroy
    @ticket.destroy
    respond_to do |format|
      format.html { redirect_to tickets_url, notice: 'Ticket was successfully deleted.' }
      format.json { head :no_content }
    end
  end

  def close
    @ticket.close!
    respond_to do |format|
      format.html { redirect_to tickets_path, notice: 'Ticket was successfully closed.' }
      format.json { head :no_content }
    end
  end


  private
  # Use callbacks to share common setup or constraints between actions.
  def set_ticket
    @ticket = Ticket.find(params[:id])
  end

  def set_neighborhood
    @neighborhood = @customer.neighborhood
  end




    # Never trust parameters from the scary internet, only allow the white list through.
    def ticket_params
      params.require(:ticket).permit(:neighborhood_id, :severity, :status, :category, :summary, :detail)
    end

end

这是票证模型：

class Ticket < ActiveRecord::Base
  belongs_to :customer
  belongs_to :tech
  belongs_to :neighborhood
  has_many :notes, as: :noteable
  has_many :appointments, as: :appointmentable


  scope :is_not_closed, ->            { where.not(status = closed)}
  scope :is_not_archived, ->          { where.not(status = archived)}
  scope :is_not_closed_or_archived, ->{ is_not_closed.is_not_archived}



  scope :hampton_park, ->             { where(neighborhood: Neighborhood.find(1))}
  scope :north_hampton, ->            { where(neighborhood: Neighborhood.find(2))}

  scope :today, ->                    { where(created_at: Date.today)}
  scope :one_week_ago, ->             { where('created_at >= ?', 1.week.ago)}
  scope :two_weeks_ago, ->            { where('created_at >= ?', 2.week.ago)}
  scope :four_weeks_ago, ->           { where('created_at >= ?', 4.week.ago)}

  # before_create :open!
  before_destroy :archived!
  # after_save :status_based_communications!


  # validates :customer_id, presence: true
  # validates_presence_of :summary

  enum status: [ :opened, :reopened, :customer_updated, :needs_to_be_scheduled, :scheduled, :in_progress, :waiting_on_customer, :closed, :archived]
  enum category: [ :billing, :plant, :cable, :internet, :internet_and_cable]
  enum severity: [ :low, :medium, :high]

  def status_based_communications!
    if self.opened?
      CustomerMailer.opened_ticket_email(@customer).deliver_now
      self.note.create(authorable_id: '999', authorable_type: 'automated', detail: 'customer was sent an email to confirm a ticket was opened' )
    elsif self.reopened
      CustomerMailer.reopened_ticket_email(@customer).deliver_now
      self.note.create(authorable_id: '999', authorable_type: 'automated', detail: 'customer was sent an email to confirm a ticket was re-opened' )
    elsif self.customer_updated
      #update slack
    elsif self.needs_to_be_scheduled
      #update slack
    elsif self.scheduled
      CustomerMailer.scheduled_ticket_email(@customer).deliver_now
      self.note.create(authorable_id: '999', authorable_type: 'automated', detail: 'customer was sent an email to confirm that an appointment was created' )
    elsif self.closed
      CustomerMailer.closed_ticket_email(@customer).deliver_now
      self.note.create(authorable_id: '999', authorable_type: 'automated', detail: 'customer was sent an email to confirm a ticket was closed' )
    else
      return true
    end
  end

  def archive!
    self.status = Status.archived
    self.save do
      return false
     end
   end

 # end

end

这是票证的架构：

create_table "tickets", force: :cascade do |t|
    t.integer  "customer_id",     limit: 4
    t.integer  "tech_id",         limit: 4
    t.integer  "note_id",         limit: 4
    t.integer  "neighborhood_id", limit: 4
    t.integer  "appointment_id",  limit: 4
    t.integer  "category",        limit: 4
    t.integer  "status",          limit: 4
    t.integer  "severity",        limit: 4
    t.string   "summary",         limit: 255
    t.text     "detail",          limit: 65535
    t.text     "resolution",      limit: 65535
    t.datetime "created_at",                    null: false
    t.datetime "updated_at",                    null: false
  end

如果您认为它相关，我可以发布该表格，但我怀疑它不相关。 更新：我在下面添加了表格。

Answer 1

只需将value 分配给表单中的fields。

<%= f.hidden_field( :category, :value => @activity.category ) %>
<%= f.hidden_field( :severity, :value => @activity.severity ) %>
<%= f.hidden_field( :status, :value => @activity.status ) %>

create 和update 在error 或edit 上的工作方式也相同，它设置表单字段的value，无论它在数据库中收到或找到什么。在new 的情况下，因为它假设您正在创建一个新表单，所以它不会预设任何东西..

Answer 2

我的解决方案是这样的。 票务员

def billing_new_1
    @ticket = Ticket.new(severity: 'low', category: 'billing', summary: 'I am having a billing issue')
    render 'new'
  end

new.html.erb

<% @title = "New Ticket" %>
<head>
  <script type="text/javascript">
  $(document).ready(function(){
      $('.ticket-customer-select').select2({
        theme: 'bootstrap'
      });
  });
</script>
</head>
<div class="container">
  <div class="row">
    <div class="col-xs-12 col-sm-12 col-md-12 col-lg-12">
