I'm using rails 2.3.5 with i18n. I's there a way to find all not yet translated locales in all views?
Maybe a after_filter in the application controller, but which code I can use for this job?
thanks
When using the i18n gem (which Rails does), you can specify your own exception handler. Try this code:
# A simple exception handler that behaves like the default exception handler
# but additionally logs missing translations to a given log.
#
module I18n
class << self
def missing_translations_logger
##missing_translations_logger ||= Logger.new("#{RAILS_ROOT}/log/missing_translations.log")
end
def missing_translations_log_handler(exception, locale, key, options)
if MissingTranslationData === exception # use MissingTranslation in Rails 3.x !!!
puts "logging #{exception.message}"
missing_translations_logger.warn(exception.message)
return exception.message
else
raise exception
end
end
end
end
I18n.exception_handler = :missing_translations_log_handler
(put it for example into RAILS_ROOT/config/initializers/i18n.rb)
Now, whenever you try to translate a key for which you have no translation specified, a warning gets printed into RAILS_ROOT/log/missing_translations.log.
Hope this helps!
I couldn't find a simple trick to do this, so I did this. First implement a 'before_filter' in your application_controller.rb
before_filter :set_user_language
# set the language, 'zen' is a special URL parameter that makes localizations the use the 't' method visible
def set_user_language
# turn on 'zen' to see localization by adding 'zen=true' to query string, will stay on until a query with 'zen=false'
session[:zen] = (session[:zen] || params[:zen] == "true") && params[:zen] != "false"
I18n.locale = 'en'
end
The above finds 'zen=true' and 'zen=false' in the query string. Then add this method to your application_helper.rb:
def t(*args)
result = super(*args)
result = "[#{result}]" if session[:zen] && result.is_a?(String)
result
end
With this method 'zen=true' makes the 't' method display localized strings in square brackets []. To turn it off enter a query string with 'zen=false'.

In debugging console, while app running (using binding.pry to interrupt it), I can see that my variable Rails.configuration.hardcoded_current_user_key is set:
pry(#<TasksController>)> Rails.configuration.hardcoded_current_user_key
=> "dev"
But it doesn't appear to be defined:
pry(#<TasksController>)> defined?(Rails.configuration.hardcoded_current_user_key)
=> nil
Yet it works fine to store and test its value:
pry(#<TasksController>)> tempVar = Rails.configuration.hardcoded_current_user_key
=> "dev"
pry(#<TasksController>)> defined?(tempVar)
=> "local-variable"
What is going on?
This is because Rails config implements respond_to? but not respond_to_missing?, and defined? only recognizes respond_to_missing?:
class X
def respond_to?(name, include_all = false)
name == :another_secret || super
end
private
def method_missing(name, *args, &block)
case name
when :super_secret
'Bingo!'
when :another_secret
'Nope.'
else
super
end
end
def respond_to_missing?(name, include_all = false)
name == :super_secret || super
end
end
x = X.new
puts x.super_secret # => Bingo!
p defined?(x.super_secret) # => "method"
puts x.another_secret # => Nope.
p defined?(x.another_secret) # => nil
It's recommended to implement respond_to_missing? along with method_missing, I too wonder why Rails did it that way.
You shouldn't be using defined? on anything but the "stub" of that, or in other words, merely this:
defined?(Rails)
Anything beyond that is highly unusual to see, and I'm not even sure it's valid.
defined? is not a method, but a construct that tests if the following thing is defined as a variable, constant or method, among other things. It won't evaluate your code, it will just test it as-is. This means method calls don't happen, and as such, can't be chained.
If you want to test that something is assigned, then you should use this:
Rails.configuration.hardcoded_current_user_key.nil?
Need a little help over here :-)
I'm trying to extend the Order class using a decorator, but I get an error back, even when I use the exactly same code from source. For example:
order_decorator.rb (the method is exactly like the source, I'm just using a decorator)
Spree::Order.class_eval do
def update_from_params(params, permitted_params, request_env = {})
success = false
#updating_params = params
run_callbacks :updating_from_params do
attributes = #updating_params[:order] ? #updating_params[:order].permit(permitted_params).delete_if { |k,v| v.nil? } : {}
# Set existing card after setting permitted parameters because
# rails would slice parameters containg ruby objects, apparently
existing_card_id = #updating_params[:order] ? #updating_params[:order][:existing_card] : nil
if existing_card_id.present?
credit_card = CreditCard.find existing_card_id
if credit_card.user_id != self.user_id || credit_card.user_id.blank?
raise Core::GatewayError.new Spree.t(:invalid_credit_card)
end
credit_card.verification_value = params[:cvc_confirm] if params[:cvc_confirm].present?
attributes[:payments_attributes].first[:source] = credit_card
attributes[:payments_attributes].first[:payment_method_id] = credit_card.payment_method_id
attributes[:payments_attributes].first.delete :source_attributes
end
if attributes[:payments_attributes]
attributes[:payments_attributes].first[:request_env] = request_env
end
success = self.update_attributes(attributes)
set_shipments_cost if self.shipments.any?
end
#updating_params = nil
success
end
end
When I run this code, spree never finds #updating_params[:order][:existing_card], even when I select an existing card. Because of that, I can never complete the transaction using a pre-existent card and bogus gateway(gives me empty blanks errors instead).
I tried to bind the method in order_decorator.rb using pry and noticed that the [:existing_card] is actuality at #updating_params' level and not at #updating_params[:order]'s level.
When I delete the decorator, the original code just works fine.
Could somebody explain to me what is wrong with my code?
Thanks,
The method you want to redefine is not really the method of the Order class. It is the method that are mixed by Checkout module within the Order class.
You can see it here: https://github.com/spree/spree/blob/master/core/app/models/spree/order/checkout.rb
Try to do what you want this way:
Create file app/models/spree/order/checkout.rb with code
Spree::Order::Checkout.class_eval do
def self.included(klass)
super
klass.class_eval do
def update_from_params(params, permitted_params, request_env = {})
...
...
...
end
end
end
end
I am building a daily deal Rails app
I am displaying to the user only the deals of the country i associate him with thanks to geocoder gem.
I wonder what would happen if geocoder fails (for any reason) to retrieve the country and sends an empty array, as i think it does when it fails to send ip( see https://github.com/alexreisner/geocoder#error-handling)
class StaticPagesController < ApplicationController
def home
#deals = deal_in_user_country.featured_on_hp
respond_to do |format|
format.html # home.html.erb
end
end
# create a scope to filter the deals that meet the user's country
def deal_in_user_country
Deal.where(country: set_location_by_ip_lookup.country || 'United States') # if geocoder gets pb then default = US version
end
end
end
As you see, I tried to use || and puts 'United States' but I don't think it will work. i think that if geocoder sends empty array , set_location_by_ip_lookup=[] and then set_location_by_ip_lookup.country will generate an error, am I right ?
How should i avoid bugs when geocoder sends an empty array ?
For info if it helps, here is how I set country in concerns/CountrySetter
module CountrySetter
extend ActiveSupport::Concern
included do
before_filter :set_location_by_ip_lookup
end
def set_location_by_ip_lookup
if Rails.env.development? or Rails.env.test?
Geocoder.search(request.remote_ip).first
else #in production
request.location
end
end
end
Your code should be fine, if geocoder allways returns at least an empty array (except I would not name this mehtod set_ because it's not setting anything)
Try out on irb
{a: [:d].first || :b}
=> {:a=>:d}
{a: [].first || :b}
=> {:a=>:b}
However i would put this in paranethesis to make it clear
Deal.where(country: (set_location_by_ip_lookup.country || 'United States'))
Gecodoer.search shouldn't be throwing exceptions, otherwise it would be named Geocoder.search! according to an unwritten ruby convention. I would double check this by plugin out the internet connection and see what happens

Put the following in an initializer to automatically clean sunspot calls of any UTF8 control characters:
# config/initializers/sunspot.rb

# field values from models for indexing. They must implement the #value_for

class AttributeExtractor
def initialize(attribute_name)
#attribute_name = attribute_name
end
def value_for(object)
Filter.new( object.send(#attribute_name) ).value
end
end
#
# BlockExtractors extract data by evaluating a block in the context of the
# object instance, or if the block takes an argument, by passing the object

Source (Sunspot Github Issues): Sunspot Solr Reindexing failing due to illegal characters
I tried the solution #thekingoftruth proposed, however it did not solve the problem. Found an alternative version of the Filter class in the same github thread that he links to and that solved my problem.
The main difference was the i use nested models through HABTM relationships.
This is my search block in the model:
searchable do
text :name, :description, :excerpt
text :venue_name do
venue.name if venue.present?
end
text :artist_name do
artists.map { |a| a.name if a.present? } if artists.present?
end
end
Here is the initializer that worked for me:
(in: config/initializers/sunspot.rb)

#value.inject({}) do |hash, (k, v)|
hash.merge( strip_control_characters_from_string(k) => strip_control_characters_from_string(v) )
end
else
#value
end
end
def strip_control_characters_from_string(value)
return value unless value.is_a? String
value.chars.inject("") do |str, char|
unless char.ascii_only? && (char.ord < 32 || char.ord == 127)
str << char
end
str

You need to get rid of control characters from UTF8 while saving your content. Solr will not reindex this properly and throw this error.
http://en.wikipedia.org/wiki/UTF-8#Codepage_layout
You can use something like this:
name.gsub!(/\p{Cc}/, "")
edit:
If you want to override it globally I think it could be possible by overriding value_for_methods in AttributeExtractor and if needed BlockExtractor.
https://github.com/sunspot/sunspot/blob/master/sunspot/lib/sunspot/data_extractor.rb
I wasn't checking this.
If you manage to add some global patch, please let me know.
I had lately same issue.
pre annotation: I have a solution, I want to understand what happens here, and if this behaviour is intended
edit a try for a better readable shortcut:
if you have the following code in Rails Controller:
def get_page
prepare_anythig params
if is_it_monday?
params=monday_default_paramms
end
finish_any_other_thing params
end
this works only on monday
Following functioning little controller function, not very intersting, I know
class SvgTestController < SiteController
def get_the_page
require "base64"
#main_width="auto"
params[:ci]||=['default']
puts "? params:",params
generate_drawing(params, false)
render ...
end
end
the console shows me how expected:
? params:
{"ci"=>"not default", "controller"=>"svg_test", "action"=>"get_the_page"}
Then I made a small (ok, erroneous or not valid as I now know - or think) change, I extended my get_the_page with 'get params via base64 encode json'
class SvgTestController < SiteController
def get_the_page
require "base64"
#main_width="auto"
params[:ci]||=['default']
# add here
puts "? params:",params
json=params[:json]
puts "json?",json.inspect
if json
plain = Base64.decode64(json)
puts "we are in here:", plain
params=JSON.parse(plain).with_indifferent_access
puts "? params now:",params
end
# end
puts "? params:",params
generate_drawing(params, false)
render ...
end
end
Solution working fine and the output like this:
? params:
{"json"=>"eyJjaSI6eyIwMDAwMDAwMDAyMDQ4MDgiOnsic3J2IjoxfX19", "controller"=>"svg_test", "action"=>"get_the_page", "ci"=>["default"]}
json?
"eyJjaSI6eyIwMDAwMDAwMDAyMDQ4MDgiOnsic3J2IjoxfX19"
we are in here:
{"ci":{"000000000204808":{"srv":1}}}
? params now:
{"ci"=>{"000000000204808"=>{"srv"=>1}}}
? params:
{"ci"=>{"000000000204808"=>{"srv"=>1}}}
later I got, working not with JSON-logic
NoMethodError in SvgTestController#get_the_page
undefined method `[]' for nil:NilClass
and my console shows me:
? params:
{"ci"=>"10.203.192.83", "controller"=>"svg_test", "action"=>"get_the_page"}
json?
nil
? params:
_(nothing to read here)_
So ruby overwrites my params (ok its a method, my fault) even if not in if ... end?
Again I ask: Is this wanted? And if, how to prevent such errors without knowing all and all the time about whats behind words like params?
edit
My solution, but not the answer to my question
...
params_used=params
json=params[:json]
if json
plain = Base64.decode64(json)
params_used=JSON.parse(plain).with_indifferent_access
end
puts "? params:",params_used
generate_drawing(params_used, false)
I think the "error" is because you're actually creating a variable. Annotation of your code:
def get_the_page
require "base64"
#main_width="auto"
params[:ci]||=['default'] # params method
# you modified #params, a mutable hash
# add here
puts "? params:",params # params method
json=params[:json] # params method
# you accessed #params[:json]
puts "json?",json.inspect
if json
plain = Base64.decode64(json)
puts "we are in here:", plain
params=JSON.parse(plain).with_indifferent_access # params variable
puts "? params now:",params # params variable
end
# end
puts "? params:",params # params variable
generate_drawing(params, false) # params variable
render ...
end
What's happening, I'd wager, is that the Ruby interpreter picks up the fact that a variable named params continues to be used after if block, so proceeds to initialize it (to nil) immediately before your if block irrespective of whether the block is visited or not.
