Hi,

Is there a way to save the output in a specific folder in my rails app please ? So far the .save_as method save the file to my root directory and passing the directory to the save_as option does not seem to work.

Thanks !

Hello, I'm having trouble loading your library.

Expected Behavior

when typing rails server in the terminal, for the dev-server to start without error.

Current Behavior

• error msg: There was an error while trying to load the gem 'fillable-pdf'. (Bundler::GemRequireError)
• Gem Load Error is: Constants DL and Fiddle is not defined.
• Typing require 'fiddle' in irb succeeds

Possible Solution

adding require: false to 'fillable-pdf' in Gemfile only pushes the error further down as RuntimeError

Steps to Reproduce

• bundle with 'rjb', '~> 1.6.1' & 'fillable-pdf' in gemfile
• try to start the server

Context (Environment)

• Ubuntu 18.04 LTS
• Ruby 2.3.8
• Rails 5.2.3
• Puma 3.11

I have a PDF form of some third-party service registration, they have around 180 fields in the form.
Unfortunately, not all the fields are coming up when I call pdf.fields method.

Thank you so much for this gem!

I need to fill form fields with strings that may contain special characters, namely the card suit symbols ♠ ♥︎ ♦ ♣. Right now, they are just getting dropped from the text.

I've read some articles on how itext will drop such characters, and you need to set a font using BaseFont, but I don't see how to do that from Rails. ITEXT::BaseFont is not recognized.

Thank you for your help.

After upgrading Rails to version 6.0.0, I received this error after running a task:

Hello, I'm getting the same error installation than my previous issue #41

extconf.rb:54:in `<main>': JAVA_HOME is not set. (RuntimeError)

although than it seems I have set JAVA_HOME ? and installed JDK

$ echo $JAVA_HOME
/usr/local/jdk-1.8.0/

$ pkg_info -Q jdk
debug-jdk-1.8.0.362.b09.1p1v0
debug-jdk-11.0.18.10.1p0v0

jdk-11.0.18.10.1p0v0
jdk-17.0.6.10.1p0v0 (installed)

In my ~/.kshrc I added export JAVA_HOME=/usr/local/jdk-1.8.0

Any idea what I'm doing wrong or what should I change?

In any fields with value included national characters, proper value is displayed only when field is "clicked/active"

In printout or preview national characters are invisible.

Working OKey only when I input manually (from Adobe Reader or macOs preview) values with national characters.

The issue is only when I fill form from RoR application (UTF-8 as default for app and DB).

Examples as attached.

I was trying to use this on AWS Lambda and it's read-only. Using /tmp would be more friendly for this type of env. Can submit a PR if you want

As said. Please answer, generating fillable PDFs in Ruby is really necessary in our current big project.

from long time:

Hello,
Anytime I try to run my server I get this error

load the gem 'fillable-pdf'. (Bundler::GemRequireError)
Gem Load Error is: Constants DL and Fiddle is not defined.
Backtrace for gem load error is:

I know there are some issues with this gem and the application server or things like spring, but I figured it would not conflict with more modern application servers but that does not seem to be the case. Has anyone seen an issue with passenger phusion and generation of PDF's on the fly in controllers. I will say I did add one function to the FillablePDF class to add a function to make streaming PDF content easier.

class FillablePDF
   def pdf_bytes(flatten: false)
     @pdf_form.flattenFields if flatten
     close
     @byte_stream.toByteArray
   end
end

Using puma locally everything works fine, but once the code is deployed to phusion the request hangs and eventually hangs all of the web requests to the server.

Thanks in advance for any ideas on how to make this gem place nicely with passenger.

Hi,

I have pdf form which has text box fields as well as some fields to attach images. How can I use this gem to add or extract images from pdf fields.

Any idea what I'm doing wrong or what should I change?

In any fields with value included national characters, proper value is displayed only when field is "clicked/active"

In printout or preview national characters are invisible.

When I input manually values with national characters, all characters are OKey.

Issue is only when I fill form from RoR application (UTF-8 as default for app and DB).

Examples are attached.

I've installed fillable-pdf in my rubymine. The methods, coming from FillablePdf class are accessible. However, when I am trying to run my feature file, it gives me the following error `import': NoClassDefFoundError. My Java_Home is set. and I am using Windows 10, ruby version is 2.4.0 . Could you pls help me on this

Using the app with Puma locally works perfectly, but hosting it on Heroku (with Puma as well) makes the code hang, whenever FillablePDF.new is called. Have you experienced the hanging with Puma as well?

What is required to use this gem with JRuby?

Setting Checkbox Values

When using set_values, it seems like if any value is set to the checkbox's key, including nil, the checkbox will be checked. The only way to uncheck the box was to remove it's associate key from the hash of values passed to that method.

Checkbox Display

After a checkbox value has been set to 'Yes' or 'Off', the actual formatting is different from what I would expect. For example, 'Off'/unchecked check boxes seem to be set to an empty square, and 'Yes'/checked boxes display both an empty box and an offset X.

Expected

(I also see this in my PDF, though the above image is closer to what I'd expect)

Actual

When filling a form with simple checkboxes in it, cannot uncheck the boxes and passing any value even nil makes the checkboxes appear checked. Looking at the pdf in adobe the values used are appearing as export values.
values tried:
true
false
"No"
"Yes"
"NO"
"YES"
""
nil
"true"
"false"
"True"
"False"
1
0
"1"
"0"

begin
pdf = FillablePDF.new(Rails.root.to_s + '/public/pdf_contracts/' + contract.template_name)
rescue Exception => e
Rails.logger.info('exception - ***')
Rails.logger.info(e.message)
ensure
Rails.logger.info('reached ensure block ')
end

So hang the server when i try to create the pdf from .new and didnt even through exception neither ensure msg displayed on production.log.

My team is considering using this library, but there are no specs included for what it looks like to include a signature in a document. What use case is supported here:

• A signature in image format, like perhaps a base64 string? (this would be best aligned with my project's use case)
• A digital signature? (which is what I suspect after looking at the iText SDK - but which wouldn't address my team's use case)
• Some other format for the signature?

Would greatly appreciate feedback from the team! Glad to also contribute updates to the spec if you can point me in the right direction for what this looks like, perhaps with a gist showing it in use, or link to a sample project?

Hi @vkononov,

I've been trying to add fillable-pdf to a new project, both locally and in Heroku.
I am using version 0.9.6 (latest) version here, but have the same problem with earlier versions. Note that between versions, the NoSuchFieldError error message changes (and stack trace as well) but still.

Getting the following error while opening any PDF file:

I've tried the same on a brand new Rails app, and also in Heroku - always getting the same error.

Any guidance would be great!

Using the following PDF form:
claim-template.pdf

And setting the following fields:

pdf.set_fields({
  "assignment.yes".to_sym => "Yes",
  "relation.self".to_sym => "Yes",
  "insurance_type.7".to_sym => "Yes",
  "sex.male".to_sym => "Yes"
})

We expect the checkboxes corresponding to the above fields to be checked.

In 0.9.4, they were checked:

In 0.9.5, they are not:

Hi, thank you for creating this gem.

I've run into an issue building a service due to FillablePDF using File.rename in its save method - this throws errors when run inside of a Docker container.

I've worked around this for now with a monkeypatch to save, that uses FileUtils.mv rather than File.rename. I can put up a PR for this if you'd like.

i tried these version for java:

but didnt work:

File not found as file or resource. (input file may be corrupt, incompatible, or may not have any forms)
I am receiving the above mentioned error when doing FillablePDF.new(path) inside my models or controllers, however it seems to work fine when I do it from rails console.
