Неверный сгенерированный код HTML.
У меня есть следующая Post модель
class Post < ActiveRecord::Base
belongs_to :user
attr_accessible :title, :description, :price, :status, :pageviews, :attachments_attributes
has_many :attachments, :as => :attachable
accepts_nested_attributes_for :attachments
validates :user_id, presence: true
validates :title, presence: true, length: { maximum: 50 }
validates :price, presence: true
validates :description, presence: true, length: { maximum: 1000 }
default_scope order: 'posts.created_at DESC'
end
my new.html.erb
<% provide(:title, "Novo anúncio")%>
<h1>Novo anúncio</h1>
<%= simple_nested_form_for @post, :html => { :multipart => true } do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class='field'>
<%= f.label "Título" %><br />
<%= f.text_field :title, size: 60, maxlength: 50 %>
</div>
<div class='field'>
<%= f.label "Descrição" %><br />
<%= f.text_area :description, cols: 100 %>
</div>
<div class='field'>
<%= f.label "Valor" %><br />
<%= f.text_field :price %>
</div>
<%= f.fields_for :attachments do |attachment_form| %>
<p><%= image_tag(attachment_form.object.file.url) if attachment_form.object.file? %></p>
<div class='field'>
<%= attachment_form.label :description %><br />
<%= attachment_form.text_area :description %>
</div>
<div class='field'>
<%= attachment_form.label :file %><br />
<%= attachment_form.file_field :file %>
</div
<%= attachment_form.link_to_remove "Remove this attachment" %>
<% end %>
<%= f.link_to_add "Add attachment", :attachments %>
<div class='actions'>
<%= f.submit "Enviar" %>
</div>
<% end %>
приведенный выше кодгенерация следующего html:
<form accept-charset="UTF-8" action="/posts" class="simple_form new_post" enctype="multipart/form-data" id="new_post" method="post" novalidate="novalidate"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓" /><input name="authenticity_token" type="hidden" value="7xO5QsSObfIO4A+FoKxCpFiqA5k3noIQBrpdwh2Iq2g=" /></div>
<div class='field'>
<label class="string optional control-label" for="post_Título"> Título</label><br />
<input id="post_title" maxlength="50" name="post[title]" size="60" type="text" />
</div>
<div class='field'>
<label class="string optional control-label" for="post_Descrição"> Descrição</label><br />
<textarea cols="100" id="post_description" name="post[description]" rows="20"></textarea>
</div>
<div class='field'>
<label class="string optional control-label" for="post_Valor"> Valor</label><br />
<input id="post_price" name="post[price]" size="30" type="text" />
</div>
<a href="javascript:void(0)" class="add_nested_fields" data-association="attachments">Add attachment</a>
<div class='actions'>
<input name="commit" type="submit" value="Enviar" />
</div>
</form><div id="attachments_fields_blueprint" style="display: none"><div class="fields">
<p></p>
<div class='field'>
<label class="text optional control-label" for="post_attachments_attributes_new_attachments_description"> Description</label><br />
<textarea cols="40" id="post_attachments_attributes_new_attachments_description" name="post[attachments_attributes][new_attachments][description]" rows="20"></textarea>
</div>
<div class='field'>
<label class="file optional control-label" for="post_attachments_attributes_new_attachments_file"> File</label><br />
<input id="post_attachments_attributes_new_attachments_file" name="post[attachments_attributes][new_attachments][file]" type="file" />
</div
<input id="post_attachments_attributes_new_attachments__destroy" name="post[attachments_attributes][new_attachments][_destroy]" type="hidden" value="false" /><a href="javascript:void(0)" class="remove_nested_fields">Remove this attachment</a>
</div></div>
Как видите, </form> вызывается ДО полей nested_attributes.
Я понятия не имею, что происходитздесь.
Ценю любую помощь.
