我希望把索引圖像到我的博客帖子 並在管理員的面板 在「新崗位」上傳表單的形式是這樣寫的:上傳圖片和文件padrino
- error = @post.errors.include?(:file)
%fieldset.control-group{:class => error ? 'has-error' : ''}
=f.label :file, :class => 'control-label'
.controls
=f.file_field :file ,:name => 'file'
- error = @post.errors.include?(:title)
%fieldset.control-group{:class => error ? 'has-error' : ''}
=f.label :title, :class => 'control-label'
.controls
=f.text_field :title, :class => 'form-control input-large input-with-feedback', :autofocus => true
%span.help-inline=error ? f.error_message_on(:title, :class => 'text-error') : pat(:example)
- error = @post.errors.include?(:body)
%fieldset.control-group{:class => error ? 'has-error' : ''}
=f.label :body, :class => 'control-label'
.controls
~f.text_area :body, :class => 'form-control input-large input-with-feedback'
%span.help-inline=error ? f.error_message_on(:body, :class => 'text-error') : pat(:example)
.form-actions
=f.submit pat(:save), :class => 'btn btn-primary'
=f.submit pat(:save_and_continue), :class => 'btn btn-info', :name => 'save_and_continue'
=link_to pat(:cancel), url(:posts, :index), :class => 'btn btn-default'
但我不不知道我在保存文件的功能上必須做些什麼。
