Error uploading large PDFs

[trans]

When I try to upload a large PDF file (800K) there is a long delay after the upload is complete and then an Application Error occurs.

This isn't enough information to help at all. Can you paste a the error stack trace? Have you made sure the the Radiant Config files allow files as large as the pdf? Do other files upload? Take a look at the mailing list, maybe there are some similar issues there.

I've been looking everywhere for three days. It works fine for other types of files --I was able to upload a 15MB .gif for instance, no problem. I am also able to upload a 100KB PDF, but an 800K .pdf fails.

I will try to gather more information about the issue. Currently this is happening on a remote host in production mode. I will setup a local install and see if it happens there too.

Download the log files, the will show the 500 error and tell you what is happening. /log/production. I could be the pdf, as well. Try it with a different, but also large pdf.

I think I may have narrowed down the issue. When installing on my host I installed the Paperclipped extension before the Settings extension. (Also, in try to adjust for that I ran rake radiant:extensions:migrate which somehow installed a bunch of language extensions I did not want.) I've noticed two strange things about my hosted radiant app vs my local app. First the icon is missing from Settings entries. Second the "Create Asset" button changed at one point and now says "Create {{name}}".

I think I need to back up somehow and install the Settings extension before the Paperclipped extension and see if that fixes it. Do you have any advice.thoughts on this?

[kbingman]

This has nothing to do with your problem. Sounds like you have two different versions of paperclipped and perhaps your environment.rb file is wrong. LikeI said, download the log files.

Your server is timing out.

ActiveRecord::StatementInvalid (Mysql::Error: MySQL server has gone away

It creates the asset and record, but cannot insert it into the MySQL database. I looks like the request is taking over a minute. Does this file upload to the local copy? We have pdfs with over 10mb, but then again, we run our own servers.

[trans]

Yes. It works with the local server. My shared host seems to be getting bogged down in the converts. It takes about a minute or so for a large PDF. I will contact my host and see if the can do anything about the timeout.

But I also wonder why Paperclipped is trying to create thumbnails for PDF files? Does that actually work? I looked at the one of assets folders for my local app, for a file called cocktails.pdf it created three other files: cocktails_icon.png, cocktails_normal.pdf and cocktails_thumbnail.png. So it does appear to work, though cocktails_normal.pdf seems out of place. Are these images of the used at all? Maybe they don't need to be created?

[kbingman]

Checkout the paperclip gem itself. You can probably turn this off.

https://github.com/thoughtbot/paperclip

[trans]

Finally got it working!!! I added the following code to vendor/extensions/paperclipped/app/models/assets.rb in the Assets class:

before_post_process :not_pdf?  # should be placed after line with has_attached_file 

def not_pdf?
  return false if (asset_content_type =~ /application\/.*pdf/)
end

So it's no longer running the PDF through convert.

The only issue I have now is that somehow in the process of working on this, the "Create Asset" button now says "Create {{name}}". Something to do with the language extensions I am sure, but why would it not be putting in the variable for name rather than showing {{name}}?

[kbingman]

Check out the yaml file in locale/en.yaml. It probably has the wrong translation. In the view, check the key and then correct it in the en.yaml file.

[trans]

I looked at the view, the button is being generated with = save_model_button(@asset). That's a built-in Radiant method that is building the button's text from @asset.class.name (see https://github.com/radiant/radiant/blob/master/app/helpers/application_helper.rb#L26). I've grep'd around, but can't find where it's getting {{name}} from.
