Question

我已经获得了＆＃34;已发布＆＃34;的初步布尔值设为＆＃39; false＆＃39;来自之前的帖子，但是从这个预览屏幕我想允许用户将此值更新为“真实”＆＃39;点击发布这篇文章，但遇到了困难。

VIEW - preview.html.erb

<div class="preview clearfix">
        <%= form_for @job, url: '/jobs/publish/' do |f| %>
        <%= f.hidden_field :publish, :value => true %>

        <span><i class="glyphicon glyphicon-exclamation-sign"></i> Review your job post! If approved, submit it, or cancel and try again.</span>

        <%= f.submit "Post Job", :class => 'btn btn-default btn-sm' %>
        <a href="/jobs/new" class="btn" style="margin-top:3px;">Cancel</a>

        <% end %>
</div>

CONTROLLER - jobs_controller.rb

class JobsController < ApplicationController
def index
    @jobs = Job.all #where(publish: true)
end

def show
    @job = Job.find(params[:id])
end

def new
end

def preview
    @job = Job.find(params[:id])
end

def create
    job = Job.new
    job.job_title = params[:job][:job_title]
    job.job_location = params[:job][:job_location]
    job.job_description = params[:job][:job_description]
    job.job_responsibilities = params[:job][:job_responsibilities]
    job.job_requirements = params[:job][:job_requirements]
    job.specialties = params[:job][:specialties]
    job.job_level = params[:job][:job_level]
    job.how_to_apply = params[:job][:how_to_apply]
    job.company = params[:job][:company]
    job.company_description = params[:job][:company_description]
    job.company_website = params[:job][:company_website]
    job.avatar = params[:job][:avatar]
    job.agree = params[:job][:agree]
    job.publish = false
    job.save!
    redirect_to '/jobs/preview/' + job.id
end

def update
    job = Job.find(params[:id])  ## Using "find"
    job.publish = true
    job.save!
    redirect_to '/jobs'
end

end

ROUTE

  post 'jobs/publish/' => 'jobs#update'

Answer 1

我注意到的一个问题是您正在使用find_by方法错误地找到Job记录。如果您必须使用find_by，则必须根据您要搜索的模型指定该模型的属性名称，这在您的案例中是缺失的。

更好的选择是在您根据主键find进行搜索时使用id方法，即params[:job][:id]引用特定{{1}的id记录。

您需要做的是，替换

Job

使用

job = Job.find_by(params[:job][:id])

-OR -

job = Job.find(params[:job][:id])  ## Using "find"

Answer 2

我得到了它的工作。我不得不将作业ID从预览页面再次传递给控制器。

<%= form_for @job, url: '/jobs/publish/'+@job.id do |f| %>

然后将控制器修改为：

def update
    job = Job.find(params[:id])
    job.publish = true
    job.save!
    redirect_to '/jobs'
end

并将路线更改为＆＃34; patch＆＃34;：

patch '/jobs/publish/:id' => 'jobs#update'
