POHow to setup Paperclip and associations for multiple models?
text
Body
copied!<p>I have 3 models which should have images associated to them:</p> <pre><code>Program.rb Episode.rb Gallery.rb </code></pre> <p>Any of them needs to have different image sizes. For example:</p> <pre><code>Program -> 100x100 , 250x400 , 500x400 Episode -> 222x450 , 210x330 , 1000x1200 Gallery -> 100x100 , 500x400 , 1000x1200 </code></pre> <p>Firstly, I thought a <code>polymorphic</code> association of a <code>Picture</code> model <code>has_attached_file</code> (Paperclip's helper) can be sufficient. Just like this:</p> <pre><code>class Picture < ActiveRecord::Base has_many :imageable, :polypmorphic=> :true has_attached_file :image, :styles => {... :program1 => "100x100>", :program2 => "250x400>", :episode1=>"222x450" , :episode2=>"210x330" , :gallery1=>"100x100" , :gallery2=>"500x400" .... } # There are almost 10 different styles for different models... end </code></pre> <p>By this way, I could use images just like this:</p> <pre><code>@program.pictures.first.image[:program1] @episode.pictures.second.image[:episode2] .. . </code></pre> <p>But I don't think that it's efficient? Is it?</p> <p><em>What is the best strategy to handle this kind of a need?</em></p> <p><em><strong>How should I build up my associations and Paperclip?</em></strong></p> <p><em><strong>For example, is it better to set paperclip for each of models?</em></strong></p> <p>I thought collecting all images inside one table would be a good practise?</p> <p>What do you think?</p> <p>This should be a common question in fact? Isn't it?</p> <p>Thank you</p>
