• 可送出简历：/jobs/1/resumes/new
• 简历内容不为空
• 使用者得登入才能提交简历
• 使用attachment栏位

Step 1: 建立投递简历的链接

app/views/jobs/show.html.erb

<div class="text-center">
  <%= link_to("投交履历", "#",  :style => 
"font-size: 30px; text-decoration: underline;" %>
</div>

Step2: 产生简历Resume 的 model

rails g model resuem job_id:integer user_id:integer content:text
rake db:migrate

step3: 将Resume 与User/Job连起来

app/models/resume.rb

class Resume < ApplicationRecord
...
+belongs_to :user
+belongs_to :job
...
end

app/models/job.rb

class Job < ApplicationRecord
...
+has_many :resume
...
end

app/models/user.rb

class User < ApplicationRecord
...
+has_many :resumes
...
end

Step4: 建立简历表单

rails g controller resumes
修改config/routes.rb

Rails.application.routes.draw do
  devise_for :users
  
  namespace :admin do 
       resources :jobs do
          member do
              post :publish 
              post :hide
           end
        end
     end

  resources :jobs do
      resources :resumes
  end

  root 'job#index'
end

修改show

app/views/jobs/show.html.erb

<div class="text-center">
  <%= link_to("投交履历", new_job_resume_path(@job), 
:style => "font-size: 30px;
 text-decoration:underline;") %>
</div>

新增resumes_controller的内容

app/controllers/resumes_controller.rb

class ResrmesController < ApplicationController
before_action :authenticate_user!
def new 
  @job = Job.find(params[:job_id])
  @resume = Resume.new
end
def create
  @job = Job.find(params[:job_id])
  @resume = Resume.new(resume_params)
@resume.job = @job
@resume.user = current_user
if @resume.save
   flash[:notice] = "成功提交履历"
   redirect_to job_path(@job)
else
   render :new
 end
end
private
def resume_params
 params.require(:resume).permit(:content)

新增app/views/resumes/new.html.erb

<h3> 投交履历到 <%= @job.title %> </h3>
<hr>
<%= simple_form_for [@job, @resume] do |f| %>
  <%= f.input :content %>
  <%= f.submit "送出" %>
<% end %>

简历内容不为空

app/models/resume.rb

class Resume < ApplicationRecord
   belongs_to :user
   belongs_to :job
   validates :content, presence: true
end

Step5: 加入简历上传功能

Gemfile

gem 'carrierwave'
bundle install

Step6:新增attachment栏位

rails g migration add_attachment_to_resume
内容：

class AddAttachmentToResume < ActiveRecord::Migration[5.0]
   def change
       add_column :resumes, :attachment, :string
    end
  end

rake db:migrate

Step7 挂上Attachment Uploader 到 Resume 上

rails g uploader attachment

app/models/resume.rb

class Resume < ApplicationRecord
    belongs_to :user
    belongs_to :job
    mount_uploader :attachment, AttachmentUploader
    validates :content, presence: true 
end

修改：

app/views/resumes/new.html.erb

<%= simple_form_for [@job, @resume] do |f| %>
  <%= f.input :content %>
  <%= f.input :attachment %>
  <%= f.submit "送出" %>
<% end %>

Step8:

app/controllers/resumes_controller.rb

def resume_params 
 params.require(:resume).permit(:content, :attachment)
end

尝试提交简历。

Step9

在.gitignore加入
public/uploads
最后commit
