Question

我有一些复选框，点击后会更新关联的模型。强制参数允许参数，但不更新模型。

＆＃39;个人资料＆＃39;模特有一排伦敦＆＃39;伦敦＆＃39;模型。

<form role="form" action="/profiles" method="post">
  <div class="form-group">

    <input type="hidden" name="authenticity_token" value="<%= form_authenticity_token %>">

    <input class="form-control" type="text" name="profile[bio]">

      <div class="checkbox">
        <label> <input type="checkbox" name="london[south]" value="south">South London</label>
      </div>

      <div class="checkbox">
        <label> <input type="checkbox" name="london[central]" value="central">Central London</label>
      </div>

      <div class="checkbox">
        <label> <input type="checkbox" name="london[north]" value="north">North London</label>
      </div>

      <div class="checkbox">
        <label> <input type="checkbox" name="london[west]" value="west">West London</label>
      </div>

      <div class="checkbox">
        <label> <input type="checkbox" name="london[east]" value="east">East London</label>
      </div>


    </div>      

    <button type="submit" class="btn btn-default">Submit</button>
  </div>
</form>

我的参数显示在rails服务器日志中：

＆＃34;个人资料＆＃34; =＆gt; {＆＃34;生物＆＃34; =＆gt;＆＃34;＆＃34;}，＆＃34;伦敦＆＃34; =＆gt; {＆＃ 34;南＆＃34; =＆gt;＆＃34;南＆＃34;，＆＃34;中心＆＃34; =＆gt;＆＃34;中心＆＃34;，＆＃34;北＆＃34; =＆gt;＆＃34;北＆＃34;}}

我的控制器：

  class ProfilesController < ApplicationController
  def new
    @profile = Profile.new

  end

  def create
      @profile = Profile.new(profile_params)
      if @profile.save 

        redirect_to '/profiles' 

      else
        render '/profiles'
      end
  end
  private

  def profile_params
    params.require(:profile).permit(:bio, londons_attributes: [:south, :north, :east, :west, :central])
  end
end

Answer 1

尝试使用

def profile_params
    params[:profile].permit!
end

Checkbox params没有创建关联模型
