Api: show

API: ShowNew Page Edit Page Page History action_group global local Set this property so link is included in a group of links.

columns local The set of columns used in the Show view. The columns themselves are not editable here – only their presence in the Show view.

formats Active scaffold supports html, js, json, yaml, and xml formats by default. If you need to add another mime type for the show action you can do it here. The format is then added to the default formats.

Examples:

config.show.formats << :pdf

or

config.show.formats = [:pdf] label local The heading used for the Show view. Normally this heading is based on the core’s label.

link global local The action link used to tie the Show view to the List table. See API: Action Link for the options on this setting.

Overrides Need to modify the show command, for example to allow a file download

class FramesController < ApplicationController

active_scaffold :frames do |config| config.show.columns << :attachment_type end

def do_show @record = find_if_allowed(params[:id], :read) end

def show_respond_to_html if params[:download] #storing the attachment in the database in a column bdata, and binary data is base64 encoded (legacy schema).
#send_file would be used if the file existed in the OS file storage system. send_data(Base64.decode64(@record.bdata), :filename => @record.filename, :disposition => "attachment", :type => @record.mime_type) else render :action => 'show' end end end

#using the "attachment_type" column to hold the download link module FramesHelper def frame_attachment_type_column(record) record.attachment_type ? link_to(record.filename, frame_path(record, :download => true)) : nil end end
