我有一个Post
模型,根据谁正在阅读Post#Show
页面,我想更改可用的表单。
我该怎么做?
即。如果是user.has_role? :guest
,并且他们点击了表单按钮,则会看到一个新的(和空的)表单。
如果是user.has_role? :editor
,并且他们点击相同的表单按钮,则会看到编辑表单。但是,他们应该能够点击“新帖子”按钮,基本上将“新表格”改为“编辑表格”。
我知道这会破坏Rails RESTFul方式,但我该如何实现呢?

我正在使用Simple_Form,所以这就是我的表单部分看起来的样子:
<%= simple_form_for(@post, html: {class: 'form-horizontal' }) do |f| %>
<%= f.error_notification %>
<%= f.input_field :parent_id, as: :hidden %>
<div class="row">
<div class="col-xs-12">
<% if can? :manage, @post %>
<label for="status">
Status
</label>
<%= f.input_field :status, label: "Status", collection: Post.statuses.keys, selected: :unconfirmed %>
<% end %>
<% if can? :manage, @post %>
<label for="title">
Title
</label>
<%= f.input_field :title, placeholder: "Enter Title" %>
<span id="wordCountTitle">0</span> words<br/>
<span class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
<% end %>
<div class="report-field">
<label for="report">
Report
</label>
<div class="input-group">
<span class="input-group-addon"><span class="fa fa-file-text"></span>
</span>
<%= f.input_field :body, id: "body-field", placeholder: "Provide all the facts of what happened, who did it, and where it happened.", class: "form-control", rows: "4" %><br />
</div>
<span class="help-block">Please avoid speculation.</span>
<span id="wordCountBody">0</span> / 150 words
</div>
<!-- <br/>
<br /> -->
<!-- <br /> -->
<label for="name">
Check if you are an eye witness:
</label>
<%= f.input_field :has_eyewitness, boolean_style: :inline %>
<br/>
<div>
<label for="photoFileUpload">Upload Images:</label>
<%= f.input_field :photo %>
<p class="help-block">Allowed: png, gif, jpg/jpeg</p>
</div>
<div>
<label for="FileUpload">Upload Documents, Video, or Audio:</label>
<%= f.input_field :file %>
<p class="help-block">Allowed: txt, pdf, doc, docx, xls, xlsx, mp4, m4v, mp3, wav.</p>
</div>
</div>
<% if can? :manage, @post %>
<%= f.input :youtube_embed_code %> <br />
<%= f.input :soundcloud_embed_code %> <br />
<% end %>
<div class="col-xs-12">
<%= f.button :submit, class: "btn btn-primary pull-left" %>
</div>
</div> <!-- //row -->
<% end %>
这是我application.html.erb
<%= render "posts/form" %>
答案 0 :(得分:1)
为表单提供Post
模型的新实例
<% if user.has_role? :guest %>
<%= form_for Post.new do |f| %>
<% end %>
<% elsif user.has_role :editor %>
<%= form_for @post do |f| %>
<% end %>
<% end %>
我肯定会重新考虑这个,过去你知道它打破了RESTful方式。您是否考虑过如果客人的帖子存在验证错误会发生什么?
