I'm able to do the bare bones keyword search with no issues in my app using elasticsearch, but as_indexed_json isn't working apparently and I have no idea why. I'm following this tutorial, and the section in question is almost halfway down.
Please let me know if I need to provide any additional info. I'm pretty new to this, so I apologize if this is a really dumb question.
Rails console:
2.2.4 :011 > Term.first.as_indexed_json
Term Load (0.4ms) SELECT "terms".* FROM "terms" ORDER BY "terms"."id" ASC LIMIT 1

as_json(

)
end
end
Based on that tutorial i hope you opened the irb using rails c.
But open console like this bundle exec rails c and try again

I'm trying to create an Active Record anonymous association extension has the documentation explains here. And I've got this models
class Program < ActiveRecord::Base
has_many :reports do
def asdf
"Hello extension"
end
end
end
class Report < ActiveRecord::Base
belongs_to :program
end
But when I test this on my rails c console I've an undefined method error.

I'm not trying to share the same extension between many associations, just trying to make this work through the anonymous module (block).
Any ideas?
That's because you retrieved many reports and called the method asdf on them, whereas your method asdf is defined for a single report.
Try this
Program.first.reports.first.asdf
(Rails 4.2.4) Hello, beginner here. I am working on a project which does not need a DB or activeRecord. Therefore, when making my Rails project I appended the -O (to disable Active Record and database) (rails new MyApp -O)
I read that to do a model not backed by a database you can just create a file in
app/models/site.rb.
No need to do:
rails generate model Site
So I added my model, which looks something like this:
class Site
attr_reader :name
attr_reader :out_average
attr_reader :in_average
attr_reader :change
def initialize(name, in_average, out_average)
#name = name
#out_average = out_average
#in_average = in_average
#change = find_increase
end
def find_increase()
if #in_average && #out_average != 0
#change = ((#in_average - #out_average)/#out_average)*100
else
#change = 0
end
return #change
end
end
So, I then started up console "rails c" and when I try to invoke a new Site object, I get an error:
irb(main):001:0> Site.new
NameError: uninitialized constant Site

I made sure I started the console from the root of my app. I also made sure to use the proper naming convention (site.rb is the filename in app/model/, "Site" is the name of my class inside the file). Can anyone help me as to why this isn't working? Is my thinking here wrong? Thanks.
My first error was that my filenames were capitalized "Site.rb", I had actually fixed this before I posted. But after I fixed it, I accidentally started using "irb" instead of "rails c". DOH! Sorry for the post.
I'm pretty sure that the problem is due to the fact that this gem looks to be 3-4 years old and rails has changed how we do migrations. But I'm not too familiar with gems/generators. I'm trying to follow the instructions to do the instructions listed here.
rails g my_zipcode_gem:models
rake db:migrate
rake zipcodes:update
However, when I do the first step I end up getting this:

Any idea what I need to do to get that gem working? It provides exactly what I'm looking for in my app.
Thanks!
Edit: Adding the generation code:
module MyZipcodeGem
class ModelsGenerator < Base
include Rails::Generators::Migration
source_root File.expand_path('../templates', __FILE__)
def initialize(*args, &block)
super
end
def generate_models
# puts ">>> generate_zipcodes:"
end
def add_gems
add_gem "mocha", :group => :test
end
def create_models
template 'zipcode_model.rb', "app/models/zipcode.rb"
template 'county_model.rb', "app/models/county.rb"
template 'state_model.rb', "app/models/state.rb"
end
# Implement the required interface for Rails::Generators::Migration.
# taken from http://github.com/rails/rails/blob/master/activerecord/lib/generators/active_record.rb
def self.next_migration_number(dirname)
if ActiveRecord::Base.timestamped_migrations
Time.now.utc.strftime("%Y%m%d%H%M%S")
else
"%.3d" % (current_migration_number(dirname) + 1)
end
end
def create_migration
migration_template 'migration.rb', "db/migrate/create_my_zipcode_gem_models.rb"
end
def create_rakefile
template 'zipcodes.rake', "lib/tasks/zipcodes.rake"
end
end
end

It looks like it is calling the migration using parameters that are no longer expected. You have two options:
1) fork the code, update it to use rails 4 conventions, and create a pull request on github. Assuming the owner is still active they will bring your code into the master and republish the gem. You would have help support the community and feel good about it in the process. There are plenty on here like myself who can help you with this.
2) Find another gem to do what you want, such as http://www.rubygeocoder.com/ which I've used several times and is awesome at doing location/zipcode problems
I am building a rails applications, where in a part of it, I save to the database, payments information. I need to make these payments un-deleteable.
I have created a before_destroy function that kinda works.. but I am having an issue:
here is my code:
class StripePayment < ActiveRecord::Base
belongs_to :user
belongs_to :stripe_card
before_destroy :fail
private
def fail
return false
end
end
When I create a payment and try out my code when delete:
StripePayment.first.destroy returns false and rollback... Which is exactly what I want.
However,
StripePayment.first.delete passes and deletes the object.
I know the deference between delete and destroy. however, I want to be able to prevent this object from being deleted on the DB (on both delete() and destroy() calls.
I tried before_delete and rails gave me back this error:
NoMethodError: undefined method `before_delete' for #<Class:0x007fc1abc37c50>

Any help will be appreciated. Thanks :)
The easiest way is, to define your own delete method
class StripePayment < ActiveRecord::Base
belongs_to :user
belongs_to :stripe_card
before_destroy :fail
def delete
false
end
private
def fail
return false
end
end
If you have conditions, where you want to allow deleteion, you can check for it iy your delete method and call super
that's because delete is one of the functions that skips callbacks in rails
check this out for more info on the subject http://edgeguides.rubyonrails.org/active_record_callbacks.html#skipping-callbacks
I use thinking-sphinx like this :
class Project < ActiveRecord::Base
define_index do
indexes title
indexes comments.message, as: :comment_message
indexes category_projects.description, as: :category_description
end
class << self
def text_search(word)
ThinkingSphinx.search(word, include: :comments)
end
end
end
When I do this Project.text_search('test') it works but I want to do this :
#projects = Project.text_search('test')
#projects.each do |project|
puts project.comment_message
end
For the moment I have this message :
undefined method `comment_message' for #<ThinkingSphinx::Search:0x000000057e11c0>

So, how to load fields into a model from thinking-sphinx?
I didn't find anything one the doc.
Thanks!
Answered on the TS mailing list as well, but essentially, the fields aren't returned by Sphinx, so you just need to refer to the associations/columns that the fields are built from:
projects.each do |project|
puts project.comments.message.join("\n")
end
