I am currently having a bit of a problem with Globalize gem.
I explain the current situation:
I have a Model called Question. After creating it, without any data stored, I added the following lines to the model:
class Question < ActiveRecord::Base
translates :wording, :answer1, :answer2, :answer3, :answer4
end
Then, I created a migration to create the translations table
class CreateTranslationsTable < ActiveRecord::Migration
def up
Question.create_translation_table! :wording => :string, :answer1 => :string, :answer2 => :string, :answer3 => :string, :answer4 => :string
def end
def down
Question.drop_translation_table!
def end
My default locale is :en. After that I added some data.
If I go execute rails c and put the command Question.first.wording everything works fine.
Although when I execute in 'rails c' I18n.locale = :es and then I do Question.first.wording still displays the english text I put at the beginning.
I tried one thing which it seemed to help me is that I dropped all the translated columns (like specified in Globalize documentation after you migrated data. In my case I didn't have any data to migrate at the beginning though). After that I made a rollback (which got back the columns I deleted form the Question model), then executing Question.first.wording with I18n.locale = :es got it working. Which means that Question.first.wording returns nil.
After that, I implemented the 'Locale from Url Params' as specified in the Ruby on Rails guide
Which means the first URL param si the ':locale' param.
Now the current problem: The view still displays the information in English when it should display it in Spanish, since the URL I entered was http://localhost.com/es/questions/.
How can I make it to display in the view the Spanish information?
My mistake. I interpreted from the documentation that the the chunck of code (in application_controller.rb) that works for setting the url:
def default_url_options(options={})
{ locale: params[:locale] }
end
would actually set the 'I18n.locale' variable. What I did is the next to get around this (in application_controller.rb):
before_action :change_to_current_locale
def change_to_current_locale
I18n.locale = params[:locale]
end
That made it work.

I have an ActiveAdmin model registered as such:
ActiveAdmin.register MyModel do
permit_params :name, :synonyms
filter :name
index do
selectable_column
column :name
actions
end
end
I noticed that when I update an object from the ActiveAdmin interface, the synonyms are getting cleared out. Synonyms are an array field defined as such in the PostgreSQL database:
synonyms text[] DEFAULT '{}'::text[]
I tried putting the following in app/admin/my_model.rb:
controller do
def update
permitted_params[:my_model][:synonyms] = JSON.parse permitted_params[:my_model][:synonyms]
super
end
end
and I also tried it with params instead of permitted_params but that doesn't work either. Not sure why ActiveAdmin would be discarding this field. Am I doing something incorrectly? The project I'm working with uses ActiveAdmin 1.0.0.pre4 (I realize this is a dated version).
Any advice would be much appreciated. Thanks in advance!
Notes: Seems this might be a common issue?
I'm not sure if this is applicable to string arrays and I don't know about that specific version of Activeadmin, but I encountered this issue in a slightly different context.
I had a model where the array data types were decimals & integers. I had to explicitly state the type of form input to be used when editing / updating the record or nothing was passed back from the field with the update parameters. Activeadmin chose a number input by default, but it needed to be processed as a string.
form do |f|
f.inputs do
f.input :ages, as :string, :input_html => {:maxlength => '100'}
end
end
I had to set maxlength manually because for some reason it was automatically being set very short. In the model, the string then has to be converted into an actual array before being saved.
def ages= items
if items.is_a? String
items = items.split(' ')
items.each do |i|
i.to_i
end
end
super items
end
We are building a Rails4 app using Trailblazer. I have never worked with Trailblazer before and I am confused about how to do things.
We are building an auction site. I was previously using a traditional controller, and this route endpoint was working fine:
def bill
#profile = Profile.find_by user_id: current_user_id
#current_order = Order.order(created_at: :desc).find_by(user_id: current_user_id)
#batch = #current_order.batch
if #batch.nil?
puts "There was no batch linked to the current order of #{#current_order.id}"
flash[:error] = "We are sorry, but we could not determine which batch your order belongs to."
else
#price_shown_to_customer = #batch.price + ENV["FUELBID_FEE_PER_GALLON"].to_f
#amount = #current_order.quantity * #price_shown_to_customer
end
But now I'm suppose to create this as a Trailblazer api, using a Representer class.
So in routes.rb I added something for "charges":
namespace :api do
get '/price' => 'info#info'
post '/order' => 'orders#create'
get '/charges' => 'charges#bill'
end
I created this Api but copying-and-pasting another:
module Api
class ChargesController < ApiApplicationController
respond_to :json
def bill
respond_with OpenStruct.new.extend(ChargesRepresenter)
end
end
end
I tested the above with a simple Representer and it all worked fine, so everything is good up to this point. If I return simple data from the Representer, then I can see it fine here:
http://localhost:3000/api/charges.json
But I need to get the current_user. How is this done? Right now, this does not work:
module ChargesRepresenter
include Roar::JSON
collection :price_shown_to_customer
def price_shown_to_customer
current_order = Order.order(created_at: :desc).find_by(user_id: current_user_id)
puts "current_order"
puts current_order.id
batch = current_order.batch
batch.price + ENV["FUELBID_FEE_PER_GALLON"].to_f
end
end
current_user_id exists in my traditional controllers because we set up Devise and so my traditional controllers inherit it:
class ChargesController < SecuredController
But is there any way to get it in a Trailblazer Representer?
Hope this answer is not too late.
If you can switch to Decorator pattern instead of a Module.
Representer really doesn't need to know and doesn't care if it is called from controller or console or test. All it needs is a hash to build your json object from. So you can just pass another attribute called current_user_id to your Representer and then use it inside r presenter like you do.
FYI:
If you need a more immediate response you can also copy your question to https://gitter.im/trailblazer/chat . There are usually several people hanging out there. But it's also good to post a question here for posterity.
I have recently added a field "tag" to my blog app built in Rails 4. Below you can see the field appearing in the Edit view:
But once I return to the Show view after editing, this does not appear:
When I check the database directly I can definitely see it exists:
sqlite> PRAGMA table_info(POSTS);
0|id|INTEGER|1||1
1|title|varchar(255)|0||0
2|body|text|0||0
3|created_at|datetime|0||0
4|updated_at|datetime|0||0
5|slug|varchar(255)|0||0
6|tag|varchar(255)|0||0
Can anyone suggest what is going on or how to troubleshoot this?
Rails 4 uses strong parameters by default. This means you have to explicitly whitelist params you wish to mass assign.
When adding a new attribute to a model, you have to remember to update the permitted params in you controller.
For example, in your case, you would need to make sure :tags are added like so:
class PostController < ActionController::Base
def update
post = Post.find(params[:id])
post.update(post_params)
redirect_to post
end
private
def post_params
params.require(:post).permit(:title, :body, :tag)
end
end
As preface, I've followed through some tutorials (i.e. Michael Hartl's) though I'm still fairly novice. Forgive any cloudy terminology.
I am trying to build a simple application in Rails 4 that does the following:
User logs into application (currently working with sign-in-with-twitter link and routing)
get "/auth/:provider/callback" => "sessions#create"
get "/signout" => "sessions#destroy", :as => :signout
Once <% if current_user %> is true, I have the view rendering a partial where there will be a list of simple buttons. When the user clicks a button I want the application to tweet on behalf of the current_user a preset string. Ideally, I'd do this all in ruby/rails.
These button functions are where I'm getting hung up. I've read a fistful of documents but there seem to be a lot of conflicting and old answers. Here's a quick list of the ones I think are closest, though not explicit about sending a tweet from a simple button/link in a view:
http://www.sitepoint.com/ruby-social-gems-twitter/
http://richonrails.com/articles/sending-a-tweet-to-twitter
Some call for controllers, a more robust oauth setup (which I have bundle installed and connected to the dev.twitter application, though not fleshed out beyond keys), and whatever else. It's got me turned around and I'm not yet good enough to synthesize all the information. Any help and direction would be great. Below are some other files in the app that might be helpful.
class SessionsController < ApplicationController
def create
auth = request.env["omniauth.auth"]
user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth)
session[:user_id] = user.id
redirect_to root_url, :notice => "Hi!"
end
def destroy
session[:user_id] = nil
redirect_to root_url, :notice => "Bye!"
end
end
And omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
provider :twitter, '_priv', '_priv'
end
Eep! I'm the author of the second link (RichOnRails). Did you take a look at the example app included with the tutorial? It does almost exactly what you want. If the tweets are hard coded you could approach it in a couple of different ways. If you take a look at the tweets controller, you'll see it takes a parameter called 'message'. Any message passed to that create method will tweet as the current user.
def create
current_user.tweet(twitter_params[:message])
end
The easiest (but not necessarily best) way to adapt this to fit your needs is to have a form for each tweet, and do a hidden field with the message you wish to tweet. The button becomes a submit for that particular form (you can add remote: true if you want to keep the page from refreshing, then use a bit of javascript to update the UI elements). Hope this helps.
I have configured RailsAdmin to use papertrail for showing the history of changes on models.
It seems to be working fine, but in the UI it displays changes always as an empty array. Is this the expected output? I was expecting to see the actual changes made on the records, or even better a drill down with a before and after change on the record.
Rails 4, RailsAdmin 0.5, PaperTrail 2.7.2
You need to have a column called object_changesin your versions table.
See these instructions from paper_trail. Look at the section called "Diffing Versions."
In short, when you generate the versions table, do this rails g paper_trail:install --with-changes
Or, if you already have an objects table, do this migration:
class AddObjectChangesColumnToVersions < ActiveRecord::Migration
def self.up
add_column :versions, :object_changes, :text
end
def self.down
remove_column :versions, :object_changes
end
end
I'm seeing the exact same thing and filed a bug report with rails_admin: https://github.com/sferik/rails_admin/issues/1751
If that is addressed I'll update this comment.
