如何使用Mongoid和Rails更新布尔值？

我已经从先前的发布中将“已发布”的布尔值初步设置为“ false”，但是在此“预览”屏幕上，我希望允许用户通过单击以将此发布发布来将该值更新为“ true” ，但遇到了困难。

查看-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>

控制器-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

路线

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

模型-job.rb

class Job
include Mongoid::Document
mount_uploader :avatar, AvatarUploader

field :job_title, type: String
field :job_location, type: String
field :job_description, type: String
field :job_responsibilities, type: String
field :job_requirements, type: String
field :specialties, type: String
field :job_level, type: String

field :how_to_apply, type: String

field :company, type: String
field :company_description, type: String
field :company_website, type: String

field :agree, type: Boolean

field :publish, type: Boolean

end
