[ANN] Table Helper for Ruby on Rails
Bauduin Raphael
11/22/2004 6:19:00 PM
Hi all,
I have put the initial release (0.1) of a table helper for Ruby on Rails
at
http://tablehelper.rub...
, with an demo page at
http://www.raphinou.com/rails/table_...
.
This component is designed to display data from an Array into an HTML table.
It is possible to display an array data in a simple html table, but also
to use more advanced features like:
- displaying certain fields of the table as links (links that can be
built thanks to the data from other fields in the row, like adding
parameters to the URL)
- displaying column headers to sort the displayed data
- manipulate the data before it gets displayed (useful for translations eg)
- styling each part of the table with CSS
- display navigation links when the number of rows is too big to be
displayed on one page
- give an id to the table and each row (for CSS or javascript
manipulation eg)
The simplest example (also available at the demo page) is like this:
simple_array = [ [ 1, "Ruby", "
http://www.ruby-lang...
],
[ 2, "Python", "
http://www.python...
],
[ 3, "Java", "
http://www.java.sun...
],
[ 4, "Perl", "
http://www.perl...
],
[ 5, "lua", "
http://www.lua...
]
]
#controller
@e = { "array" => simple_array }
#view
<%= table(@e1, "display" => :default) %>
All further parameters are passed to the helper by instantiating the
TableFields class.
To give an id to the table, we can do this:
#controller
fields = TableFields.new(:table_id => "example")
@e = { "array" => simple_array , "fields" => fields}
We can set the column names:
fields.field_names = [ "id", "name", "homepage"]
Links are defined thanks to the LinkSpec class. Eg:
ror_link_spec = LinkSpec.new
ror_link_spec.href = "
http://www.rubyonrails...
fields.add_link("column_name", ror_link_spec)
A link built with the data in the array is also simple, but I'll let you
discover this and the other features at the demo page. Feedback and
comments are welcome.
