    <p>I'm trying to upload javascript files with paperclip and geting </p> <pre><code>No handler found for "application/javascript" .../paperclip-3.2.0/lib/paperclip/io_adapters/registry.rb:19:in `handler_for' .../paperclip-3.2.0/lib/paperclip/io_adapters/registry.rb:29:in `for' .../paperclip-3.2.0/lib/paperclip/attachment.rb:91:in `assign' .../paperclip-3.2.0/lib/paperclip.rb:196:in `block in has_attached_file' </code></pre> <p>I am using this as part of a templating system. As part of my seed.rb (so I'm not uploading this via a form) I loop through files in a directory, create a new Javascript object for each one, set 'path', 'extension' and 'body' and then a callback sets the paperclip attachment named 'source' before validation and another attachment named 'preview' after save. The error is occurring in <code>compile_preview</code> at <code>self.preview = file</code></p> <p>models/javascript.rb</p> <pre><code>has_attached_file :source, :default_style =&gt; :original, :path =&gt; ":rails_root/tmp/:configured_path", :url =&gt; ":configured_url", :default_url =&gt; "/assets/missing.gif", :use_timestamp =&gt; false, :storage =&gt; :filesystem before_validation :set_source before_post_process { false } after_save :compile_preview validates :body, :presence =&gt; true, :length =&gt; { :maximum =&gt; 500.kilobytes } validates :path, :presence =&gt; true validates :format, :presence =&gt; true, :inclusion =&gt; ["js"] validates :handler, :presence =&gt; true, :inclusion =&gt; ["coffee", "js"] def set_source file = StringIO.new(self.body) file.class.class_eval { attr_accessor :original_filename, :content_type } file.original_filename = "#{File.basename(self.path)}.#{self.extension}" file.content_type = "application/javascript" self.source = file end def compile_preview file = StringIO.new(self.render) file.class.class_eval { attr_accessor :original_filename, :content_type } file.original_filename = self.source_file_name file.content_type = self.source_content_type self.preview = file self.save end </code></pre> <p>I know 99% of this works because I've used it with another model, but it's just "application/javascript" which is causing a problem. I've also tried "text/plain" and the old "text/javascript" mime type too but get the same error.</p> <p>I see no mention of anyone having problems with handlers in this way before and paperclip has no mention of it.</p> <p>I'm using Rails 3.2.8 &amp; Paperclip 3.2.0</p> <p>Could my <code>handler</code> attribute be conflicting with paperclip?</p> <p>Does anyone have any insight into where I'm going wrong with this? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
