It's Working...Finally!!


For the last few days I have been struggling getting my one month rails app to upload pins to amazon’s S3 service. Basically, I wouldn’t get any error but just a broken link icon. I tried for a couple of hours the first night debugging it but just got frustrated and moved on to some other ruby exercises. Yesterday, I went back starting fresh looking for a solution. No luck, no matter what I searched for I couldn’t find anything. I even checked my code against the one month rails source and couldn’t find any differences.

So tonight I started really digging into it, I had send an email off to one month rails and got a couple of suggestions which I tried and didn’t work. Finally, I found a problem…

1
2
3
4
  <div class="form-group">  
   <%= f.label :image %>  
   <%= f.file_field :description, class: "form-control" %>  
  </div>  

See the problem there…Well, I must have cut and pasted from another line and forgot to change “description” in f.file_field to “image”. Anyway, saved it, pushed it…error..

Now, I started getting errors about a missing bucket. Fast forward an hour of so and I realize in the production environment I had:

1
2
3
 :bucket => ENV['S3_BUCKET']  
 instead of  
 :bucket => ENV['AWS_BUCKET']

I went ahead and fixed this error, went through the github/heroku dance, opened the page and another error. Looking into heroku logs I see:

 2014-05-27T01:40:46.117103+00:00 app[web.1]: Paperclip::Errors::MissingRequiredValidatorError (Paperclip::Errors::MissingRequiredValidatorError):  
 2014-05-27T01:40:46.117104+00:00 app[web.1]:  app/controllers/pins_controller.rb:21:in `create'  

A little while later along with some advice from stackoverflow and the paperclip documentation, I find you now need a validator for the image attachment in the pin model. I added this and what do you know….Success!

Aside for the rails app I am working on, I’ve been doing some of “ruby the hard way” which is great so far. I’ve found it to be fairly easy but granted I am not that far along. I suppose some of the other ruby tutorials/books/courses I’ve taken are paying off. Till next time…
