ruby '2.5.1'
rails '5.1.7'
My project is for sound management. All uploaded files are in the cloud storage - sounds/sound images/album images and etc.
But some files on cloud storage are absent. And for following code in view:
.row
- #sounds.each do |sound|
.col-md-2
.play{ "image-src": "#{sound.image.url(:small)}", style: "background: url(#{sound.image.url(:small)});" }
I get following error:
ActionView::Template::Error (undefined method `public_url' for nil:NilClass)
There are a lot of such cycles (#sounds.each) in the project, so I would not want to rewrite each one.
How to write an error handler for such case? So that in absence of files in storage, sound is skipped.
Maybe there is a way to write code in application_controller.rb or something similar?
I use gem 'carrierwave-google-storage' for images and gem 'google-cloud-storage' for attachment.
It seems that there are some cases where the error ActionView::Template::Error (undefined method `public_url' for nil:NilClass) occurs.
Looking on the Community, it seems that there are some options/ways that can fix this error and it would depend on the way that your code and application is configured. For this reason, I would recommend you to take a look at the following posts and answers, to check if they help you. :)

I am getting an error:
NoMethodError: undefined method `cards' for
V1::CardsControllerTest:0x00000007c17238
when I am making the following call in an integration test:
card = cards(:one)
even though I have defined the fixture 'Cards'.
Does anyone have an idea as to why this is happening?
I tried to deploy a non public project but sometimes when tried to use
report pages (based on prawn) I have this problem:
NoMethodError (undefined method `get_yaml' for #<String:0x7fdecffd3738>):
The piece of code is:
report_content = report.draw(report_content.get_yaml)
Someone know: where are get_yaml come from?
Thanks.
The method #get_yaml is not a part of of the standard Ruby library, although #to_yaml is defined if the yaml library has been loaded. #get_yaml, if it exists, is defined by the application or by some library that the application is loading.
Using rails_admin, I whenever I try to save an object that has a date field, I get the error message: undefined method 'year' for nil:NilClass. Not sure what's going on.
Turns out it's a bug that's introduced with Ruby 2.2.*
Not sure if it's on the rails_admin team's radar yet, but you can fix it by downgrading to 2.1.*
Currently when I look in the log files of my rails application I get stacktraces like:
NoMethodError (undefined method `[]' for nil:NilClass):
app/controllers/concerns/example.rb:192:in `rescue in create_example'
app/controllers/concerns/example.rb:163:in `create_example'
app/controllers/concerns/example.rb:11:in `example'
app/controllers/example_controller.rb:39:in `create'
The error is triggered from a second project which is included as gem.
On line 192 in the example.rb (concern) we use some classes from that included gem and in that class the real exception occurs.
Another example:
ZeroDivisionError (divided by 0):
app/controllers/dummy_controller.rb:15:in `index'
And on line 15
test_object.divide_by_zero
test_object is an instance of a class defined in the included gem
I want rails to display and log the full stacktrace including all or specific gems but I can't figure out how to do this. Does someone know how to do this? or someone that can give me a push in the right direction?
Thanks!!!
It's used like this:
Rails.backtrace_cleaner.remove_silencers!
Depending on what version of rails you are using this may help:

I am getting undefined method [] for true:TrueClass error while running the rake task in acts_as_recommendable plugin. The error points to the following line.
items = options[:on_class].find(:all).collect(&:id)
Can someone please tell what am i doing incorrectly.
options is probably defined as true. We can't really know why without more information.
