Spreadsheet Architect
Spreadsheet Architect lets you turn any activerecord relation or plain ruby class object into a XLSX, ODS, or CSV spreadsheets. Generates columns from model activerecord column_names or from an array of ruby methods.
Spreadsheet Architect adds the following methods to your class:
# Plain Ruby
Post.to_xlsx(data: posts_array)
Post.to_ods(data: posts_array)
Post.to_csv(data: posts_array)
# Rails
Post.order(name: :asc).where(published: true).to_xlsx
Post.order(name: :asc).where(published: true).to_ods
Post.order(name: :asc).where(published: true).to_csv
Note: Breaking Changes in 1.1.0
The spreadsheet_columns
method has been moved from the class to the instance. So now you can use string interpolation in your values. Please re-read the Model section below to see the changes. The side effect of this is if you are using the spreadsheet_columns option directly on the .to_* methods.
Install
gem install spreadsheet_architect
Setup
Model
class Post < ActiveRecord::Base #activerecord not required
include SpreadsheetArchitect
belongs_to :author
belongs_to :category
has_many :tags
#optional for activerecord classes, defaults to the models column_names
def spreadsheet_columns
#[[Label, Method/Statement to Call on each Instance]....]
[
['Title', :title],
['Content', content],
['Author', (.name rescue nil)],
['Published?', (published ? 'Yes' : 'No')],
['Category/Tags', "#{category.name} - #{.collect(&:name).join(', ')}"]
]
# OR just humanize the method to use as the label ex. "Title", "Content", "Author Name", "Published"
[:title, content, (.name rescue nil), :published]
# OR a Combination of Both
[:title, :content, ['Author',(.name rescue nil)], :published]
end
end
Usage
Method 1: Controller (for Rails)
class PostsController < ActionController::Base
respond_to :html, :xlsx, :ods, :csv
# Using respond_with
def index
@posts = Post.order(published_at: :asc)
respond_with @posts
end
# Using respond_with with custom options
def index
@posts = Post.order(published_at: :asc)
if ['xlsx','ods','csv'].include?(request.format)
respond_with @posts.to_xlsx(row_style: {bold: true}), filename: 'Posts'
else
respond_with @posts
end
end
# Using responders
def index
@posts = Post.order(published_at: :asc)
respond_to do |format|
format.html
format.xlsx { render xlsx: @posts }
format.ods { render ods: @posts }
format.csv{ render csv: @posts }
end
end
# Using responders with custom options
def index
@posts = Post.order(published_at: :asc)
respond_to do |format|
format.html
format.xlsx { render xlsx: @posts.to_xlsx(headers: false) }
format.ods { render ods: Post.to_odf(data: @posts) }
format.csv{ render csv: @posts.to_csv(headers: false), file_name: 'articles' }
end
end
end
Method 2: Save to a file manually
File.open('path/to/file.xlsx') do |f|
f.write{ Post.order(published_at: :asc).to_xlsx }
end
File.open('path/to/file.ods') do |f|
f.write{ Post.order(published_at: :asc).to_ods }
end
File.open('path/to/file.csv') do |f|
f.write{ Post.order(published_at: :asc).to_csv }
end
# Ex. with plain ruby class
File.open('path/to/file.xlsx') do |f|
f.write{ Post.to_xlsx(data: posts_array) }
end
Method Options
to_xlsx, to_ods, to_csv
data - Array - Mainly for Plain Ruby objects pass in an array of instances. Optional for ActiveRecord relations, you can just chain the method to the end of your relation. If Plain Ruby object it defaults to the instances to_a
method.
headers - Boolean - Default: true - Pass in false if you do not want a header row.
spreadsheet_columns - Array - Use this to override the models spreadsheet_columns/column_names method for one time. Must use symbols that correspond to instance methods of the object. Ex: [:name, :title, :address]
or [['Name',:name],['Post Title', :title],['Address', :address]]
to_xlsx
sheet_name - String
header_style - Hash - Default: {background_color: "AAAAAA", color: "FFFFFF", align: :center, font_name: 'Arial', font_size: 10, bold: false, italic: false, underline: false}
row_style - Hash - Default: {background_color: nil, color: "FFFFFF", align: :left, font_name: 'Arial', font_size: 10, bold: false, italic: false, underline: false}
to_ods
sheet_name - String
header_style - Hash - Default: "000000", align: :center, font_size: 10, bold: true - Note: Currently only supports these options
