Ruby On Rails Plugin Uni Admin For Admin Layout

Today I code a new simple plugin Uni_Admin. Uni Admin is a simple administration layout support for ruby on rails web application. Now it includes:

• an admin base controller and dashboard action
• a simple admin layout
• a simple admin CSS file
• an integrated admin menu
• a record list table style

Demo:

Rails ActiveMerchant Patch For BeanStream

I submitted the patch to active merchant plugin for Canada payment gateway BeanStream. I guess that it will take some time to get reviewed, tested and accepted ( or not accepted because the remote test can not be passed without beanstream's test account which it doesn't provide it to me), so I uploaded the patch to a google code project:

http://code.google.com/p/activemerchant-patch-for-beanstream/

The installation, description and a simple example have been already written in the project home page. Issue your bug or give me your feedback if you encounter any problem when using it.

A Rails Plugin table_styles to let you easily use up to 42 different css styles for HTML table.

Today I wrote a rails plugin based on CSS Table Gallery .

I upload to google code: http://code.google.com/p/rails-plugin-table-styles/

Installation

script/plugin install http://rails-plugin-table-styles.googlecode.com/svn/trunk/table_styles

Usage

* Use the demo to find one of your favorable style.

# Start your server: >script/server
# Visit http://localhost:3000/table_styles_demo/
# Remember to add map.connect :controller/:action in your routes.rb

* Choose one of table styles in your layout header, use "tagbox" as an example.

<%= table_stylesheet_link_tag "tagbox" %>

* Just use table tag it in your view

* Use form helper if you want to let admin user to choose table style in user preferences page.

table_style_select or table_style_options_for_select

Basic flow to use rails file_column plugin

1. Create your table with a string field to store file name. For example:

create_table :products do |t|
t.string "name"
t.string "model"
t.string "image"
t.timestamps
end

2. Install file_column plugin:

script/plugin install http://opensvn.csie.org/rails_file_column/plugins/file_column/trunk

3. Install ImageMagick to your system and plugin RMagick

Visit http://rmagick.rubyforge.org/ for more detail

4. Put file_column description for model field into your model code. For example here, add to product.rb:

file_column :image, :magick => {
:versions => { "thumb" => "60x60", "medium" => "320x240"}
}

5. Generate controller and views for your model. I use rails 2.0 scaffold generator here:

script/generate scaffold product --skip-migration
add layout and authentication before_filter to product controller if needed
add _form.html.erb with form fields for new.html.erb and edit.html.erb to use
edit index.html.erb to show the list of products, such as <%= f.text_field :name %>

6. Show and upload image of product, edit in the _form.html.erb:

remove <%= f.text_field :image %>
add:
<% if !@product.id.nil? # in the case of edit %>
<%= image_tag url_for_file_column("product", "image", "medium") %>
<% end %>
<%= file_column_field "product", "image" %>

7. Add multipart to form tag in the edit and new files.

<% form_for(@product, :html => {:multipart => true}) do |f| %>

8. To show image in the list:

<% @product = product %>
<%= image_tag url_for_file_column("product", "image", "thumb") %>

Install and config rails plugin restful_authentication

Ruby on rails plugin Restful_authentication is a basic plugin useful for most of rails applications. It is very easy to intall and config it:

script/plugin source http://svn.techno-weenie.net/projects/plugins
script/plugin install restful_authentication
script/generate authenticated user sessions
rake db:migrate

Check the code in your routes.rb which is automatically added by the generation

map.resources :users
map.resource :session

Add more route mapping if your want

map.signup '/signup', :controller => 'users', :action => 'new'
map.login '/login', :controller => 'sessions', :action => 'new'
map.logout '/logout', :controller => 'sessions', :action => 'destroy'

Visit http://localhost:3000/users/new or http://localhost:3000/signup

Then to make it work with Comatose, add comatose config to evironment.rb of your app:

Comatose.configure do |config|
# Includes AuthenticationSystem in the ComatoseAdminController
config.admin_includes << :authenticated_system

# Calls :login_required as a before_filter
config.admin_authorization = :login_required
end

Some problems of the installation of Rails Comatose Plugin

Comatose is a very handy content management ruby on rails plugin. Here I am listing some problems that I encountered when I get Comatose running correctly. Most of them can be easily fixed by googling. It is just a quick summary just in case you get the same kinds of problems or errors as I did.

To install it:

script/plugin install http://comatose-plugin.googlecode.com/svn/trunk/comatose
script/generate comatose_migration
rake db:migrate
# add to your routes.rb:
map.comatose_admin
map.comatose_root 'pages'
script/server
# visit content admin http://localhost:3000/comatose_admin
# after add a page of name My Page
# visit it at http://localhost:3000/pages/my-page

1. Do rake db migration, get a Mysql::Error: BLOB/TEXT column 'full_path' can't have a default value. To fix it, remove ":default => ''" from the definition of column 'full_path', in the migration file db/migrate/xxx_add_comatose_support.rb

2. To start your rails app, get an error `method_missing': undefined method `comatose_admin' for #. I got this routing error after I use Active Merchant plugin, can not figure out why. Add this to environment.rb to make Comatose plugin be loaded firstly:

config.plugins = [ :comatose, :all ]

3. Install necessary plugins

./script/plugin install acts_as_tree
./script/plugin install acts_as_list

4. To customize comatose admin view

rake comatose:admin:customize

This task will copy all of admin view rthml files to app/view/comatose_admin directory of your rails app. There is a new layout file comatose_admin.rhtml. Modify this layout file to customize your admin view.
