# Introduction

Error messages are currently not handled in a consistent manner in Batchdeux's forms. I have modified the `field_error_proc` method which serves as a global way to change the behavior of form errors. By modifying this, I have given us the option to display errors in several ways:

# Options

Options can be passed on an individual `:input` basis. 

* `suppress_error` - Do not show any inline errors
* `error_before` - Show the label tag before the :input tag

Demo

git fetch
git checkout bls/23176299_data_validation_errors

Be sure to restart your webserver, as changes have been made to the config/ directory

Intro

I have a Ruby model that needs to have a configuration option passed to it i.e. config/initializers/contact_import.rb define options so that:

ContactImport.import_mapping # => {'csv' => ..., 'csv_row' => ..., etc}

Option 1

Works in production environment, but not in development since classes reload

config/initializers/contact_import.rb

Intro

The class below has a Paperclip attachment that is stored on S3. The attachment has a custom processor that takes dimensions and crops the image from user defined points. There is a need to move this post-processed attachment from one contact to another, and the copy_avatar_to methods accomplishes this without reprocessing the attachment. Reprocessing would result in the cropping points being lost, and the original image source being copied over, and resized according to the styles.

Code Example

#  avatar_content_type :string(255)
#  avatar_file_name    :string(255)
#  avatar_file_size    :integer

avatar_updated_at :datetime
