i built a simple sitemap with the gem sitemap generator.
It is supposed to list the job pages of my application.
E.g. www.mydomain.com/vacancies/24
There is a bug that I cannot fix myself for days:
It shows the wrong indexes (that do not exist). E.g.
www.mydomain.com/vacancies/645
enter code hereHere is my sitemap.rb file:
require 'rubygems'
require 'sitemap_generator'
SitemapGenerator::Sitemap.default_host = "http://www.frankfurtstartupjobs.com"
SitemapGenerator::Sitemap.create do
Vacancy.find_each do |vacancy|
add vacancy_path(vacancy), :lastmod => vacancy.updated_at, :priority => 0.5
end
end

I have been learning Ruby on Rails, but I still have issues when it comes to Ruby gems with examples that are irb based and not Rails or Sinatra framework based. I am trying to implement the Block.io Bitcoin API functionality. But the code I find is Ruby only, so I am not sure where to create a config file for the API Key and also whether I need to create a controller to make this work in the views for Rails.
The gem and examples are on: https://github.com/BlockIo/gem-block-io
I installed this gem via bundle install on Rails
gem install block_io -v=1.0.6
The Ruby example show the following:
>> require 'block_io'
>> BlockIo.set_options :api_key=> 'API KEY', :pin => 'SECRET PIN', :version => 2
In Rails which config file would I enter the above api_key and pin?
In the example they show the code to get your address as follows:
BlockIo.get_my_address
Do I need to create a function in a controller such as:
def address
#my_address = BlockIo.get_my_addresses
end
and in the view use:
<%= #my_address %>
I need some guidance with regards to the above, any comment or assistance will be greatly appreciated.
require 'block_io' can go into Gemfile like gem 'block_io'. Rails/bundler will require it automaticaly for you as long as the gem name is also the file name you want to require from this gem.
BlockIo.set_options :api_key=> 'API KEY', :pin => 'SECRET PIN', :version => 2 can be put into an initilizer like config/initializers/block_io.rb. This way set_options is called only once when Rails starts a server or console or runner.
Put it like this into the file config/initializers/block_io.rb
BlockIo.set_options :api_key=> ENV['BLOCK_IO_API_KEY'], :pin => ENV['BLOCK_IO_PIN'], :version => 2
With the environment variables in use you don't commit any secret into your repo.
Now you should be able to call BlockIo.get_my_address within any action.
I want to use this gem (sitemap_generator)
sitemap_generator
To create my sitemap xml file for my site.
So i create sitemap.rb inside config folder
Then i put this code inside
require 'rubygems'
require 'sitemap_generator'
SitemapGenerator::Sitemap.default_host = 'https://xxxx.com/'
SitemapGenerator::Sitemap.create do
# add '/home', :changefreq => 'daily', :priority => 0.9
# add '/contact_us', :changefreq => 'weekly'
add '/'
add '/signup'
add '/login'
Activity.find_each do |activity|
add activity_show_path(activity.id), :lastmod => activity.created_at
end
end
SitemapGenerator::Sitemap.ping_search_engines # Not needed if you use the rake tasks
But when i run
ruby config/sitemap.rb
I always got this
uninitialized constant Activity (NameError)
So how can i fixed this
(I guess the problem from the model)
Thanks!
I always run it through the rake task, try this:
rake sitemap:refresh:no_ping
It's possible the rake task does the magic to make the application code available when that's running.
Update: probably a duplicate of Rails sitemap_generator Uninitialized Constant? (sorry I should have looked first)
I have a ROR apps that selling items such as chair, table etc. I am using gem sitemap_generator to generate the sitemap. Here is the code of my sitemap:
# Set the host name for URL creation
SitemapGenerator::Sitemap.default_host = "http://www.example.com"
SitemapGenerator::Sitemap.create do
add '/products', :priority => 0.7, :changefreq => 'daily'
end
When I run the command rake sitemap:refresh a sitemap.xml.gz is created in public folder.
My robots.txt as follow:
# See http://www.robotstxt.org/robotstxt.html for documentation on how to use the robots.txt file
#
# To ban all spiders from the entire site uncomment the next two lines:
# User-agent: *
# Disallow: /
Sitemap: http://www.example.com/sitemap.xml.gz
Would this mean, all my products at www.example.com/products will be available for google to index?
Thanks!!
Firstly, you're better off using the url helpers rather than explicit paths. This way if the paths ever change due to modifications to your routes.rb file, you wont need to worry about your sitemap being wrong:
SitemapGenerator::Sitemap.create do
add products_url, priority: 0.7, changefreq: 'daily'
end
Next, the products url you've added above will only add /products to your sitemap. You might want to add each individual product, depending on the frequency of them changing:
SitemapGenerator::Sitemap.create do
add products_path, priority: 0.7, changefreq: 'daily'
Product.all.each do |product|
add product_path(product), priority: 0.7, changefreq: 'daily'
end
end
Obviously, you will need to trigger a sitemap refresh each time you add/remove a product.
I have a MySQL table and I want to pick certain columns to create RSS Feed from it. How to do it using Ruby or Rails or Gems?
Depending on what I was trying to do, I would probably just go for a simple Ruby script. I would use ActiveRecord so I didn't have to write any SQL. Then I would use either Builder or RubyRSS to generate the feed.
Connecting ActiveRecord to a MySQL server directly is as simple as:
require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter => "mysql",
:host => "localhost",
:username => "myusername",
:password => "mypassword",
:database => "mydb"
)
Then you are free to define ActiveRecord models like you would in a regular Rails app.
There are RSS generator examples on the RubyRSS website and a Builder one on the Railscasts website.
Hernan is right...here is are the full steps you'll need to get data from the database (I moved the code to below the steps for easier formatting:
Install ActiveRecord: sudo gem install activerecord
Establish the connection per hernan43's recommendation (preferrably in a separate file, let's call it "connection.rb"
Create a class that uses that connection by inheriting from ActiveRecord
Retrieve record(s) from the table, and use it/them to populate your RSS generator
You don't have to separate everything out into a file...you could put everything below in one file, and remove the 'requires' in files 2 and 3, but it's a convention to separate out your concerns in a manner similar to what I've done.
#1: file connection.rb
require 'rubygems'
require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter => "mysql",
:host => "localhost",
:database => "appdb",
:username => "appuser",
:password => "secret"
)
#2 filename: singural_rss_table_name.rb
require 'connection'
class SingularRSSTableName < ActiveRecord::Base
set_table_name 'real_database_table_name' #if the table name is the lowercase, underscore plural of the class name, then you don't need this line.
end
#3 filename: rss_creator_file.rb
require 'singular_rss_table_name'
# Here you retrieve the rows from your database table,
# based on the condition that the column 'title' is exactly the text 'article_title'
# there are a lot more options for
# conditions in ActiveRecord, and you'll probably want to look them up.
records_for_rss_entries = SingularRssTableName.find(:all, :conditions => {:title => 'article_title'})
rss_object = RSS::Maker.new(version) do |feed|
feed.channel.title = "Example Ruby RSS feed"
records_for_rss_entries.each do |entry_record| # here we're iterating through
# each of the rows we found.
entry = feed.items.new_item
entry.title = entry_record.title # at this point, each 'entry_record' is a row in your db table
# use the dot (.) operator to access columns in the table.
...
end
end

i have looked through the list of related questions however my problem does not seem to be listed and hence here it is:
Basically I'm trying to use Geokit within the Ruby on Rails environment, im not sure if i installed it properly, I have included it within the environment.rb (and done rake db:install) and i'm now trying to do the following:
require 'active_record'
require 'geokit'
class Store < ActiveRecord::Base
acts_as_mappable
end
Unforunately, when i try to run this and see if its ok, i get the following error:
c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/base.rb:1959:in `method_missing': undefined local variable or method `acts_as_mappable' for #<Class:0x4cd261c> (NameError)
from C:/Users/Erika/Documents/Visual Studio 2008/Projects/StoreLocator/StoreLocator/app/models/store.rb:5
I am running Ruby in Steel for Visual Studio 2008, i'm not sure what i'm doing wrong as all the online tutorials i find tend to be rather old and done apply to me. Any help would be greatly appreciated. thanks!

acts_as_mappable is part of geokit-rails. You need to install the geokit-rails plugin.
script/plugin install git://github.com/andre/geokit-rails.git
To check if the plugin is properly installed, look under the vendor/plugins directory of your Rails app. It should have a geokit-rails sub directory. It it, you'll find all the plugin files, other subdirectories, including the file acts_as_mappable.rb (in vendor\plugins\geokit-rails\lib\geokit-rails).
If everything seems to be properly installed, try adding "require geokit" to the top of the init.rb file in the plugin root folder (vendor\plugins\geokit-rails).
Be sure to restart your app server after making the modifications.
What method are you using to include the geokit library? The plugin? The gem? Is the gem unpacked into vendor? What does your environment.rb look like?
Edit: I meant to leave this as a comment on the question - pardon me.
