How to migrate old images saved by Paperclip to new styles and save it to s3 (and not saving the new files locally) ? (Rails) -

-

I used to use Rail (4.0.1) with paperclip (4.2.0) to save some images in S3 I am here.

I used to have a model property image: 

  class property image & lt; ActiveRecord :: Base has_attached_file: painting, storage :: s3, s3_credentials: CONFIG [ 's3'], s3_protocol: (Rails.env.development? "Http": "https") end

Now I want to transfer old images to new sizes, so I updated the model: 

  class PropertyImage & lt; ActiveRecord :: Base has_attached_file: painting, storage :: s3, s3_credentials: CONFIG [ 's3'], s3_protocol: (Rails.env.development? "Http": "https"), Style: {thumb: '100x100 & gt; ' , Large: '633x460 & gt;', Medium: '301x240 & gt;' }  
 
  RAILS_ENV = D Bundle Exec rack paperclip refresh Class = property Image  
 
 And when I see the logs do, I get : 
 
  (0.2ms) BEGIN Property Load (0.7 ms) "Select" from "Properties" (where hidden I is hidden or I have hidden) and "Property". "Id" = $ 1 "Properties" by ORDER "Id" ASC LIMIT 1 [[ "id", 20]] SQL (0.6 mms) Update "Properties" SET "Apdeted_at" = "2014-10-28 12: 33: 58.382649 'where' quality '." Id "= 20 (1.7 ms)) COMMIT [paperclip] copying /property_images/pictures/000/000/074/original/e9ad004a-09f1-4af3-85c3-772fe3e99acd.gif local file / var / folders / g8 / 3v37gc0x16b313mvf7464qtc0000gn / T / 2c5a0dd4db750ff6c32b123df2d933ce20141028-28547-j997pz GIF [AWS S3 200 0.209569 0 Comments] get_object (: balt_name = & gt; "babylon_development" ,: key => "property_image / image / 000/00  
 
 Two things that I have seen here: 
 
 1- Dana is trying to localize the original images on  / var / folders / *  (not on s3) < / P> 
 2 - grains of different sizes (thumbs, large And medium) is not being made 
 
 Any help will be highly appreciated

I missing_styles just like: 

  Bundle App Reich paperclip: Refresh: missing_styles class = PropertyImage

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
