1、安装gem "wice_grid",

2、运行rails g wice_grid:install生成

create config/initializers/wice_grid_config.rb

create config/locales/wice_grid.yml

create app/assets/stylesheets/wice_grid.css.scss

此时查看application中是否有//= require wice_grid，如果没有，则添加，该句意思是引入该插件的js文件

3、controller层使用

基本使用@tasks_grid = initialize_grid(Task)

加入一些条件@tasks_grid = initialize_grid(Task.where(:active => true))

4、view层使用

<%= grid(@tasks_grid) do |g|  g.column do |task|    task.id  end  g.column  do |task|    task.title  end  g.column do |task|    task.description  end  g.column do |task|    task.archived? ? 'Yes' : 'No'  end  g.column do |task|    link_to('Edit', edit_task_path(task))  endend -%>

也可以写成下面的形式

<%= grid(@tasks_grid) do |g|  g.column :name => 'ID', :attribute => 'id' do |task|    task.id  end  g.column :name => 'Title', :attribute => 'title'  do |task|    task.title  end  g.column  :name => 'Description', :attribute => 'description' do |task|    task.description  end  g.column  :name => 'Archived', :attribute => 'archived' do |task|    task.archived? ? 'Yes' : 'No'  end  g.column   do |task|    link_to('Edit', edit_task_path(task))  endend -%>

5、条件查询。一下是该插件在controller层使用可传入的参数

@tasks_grid = initialize_grid(Task,  :order => 'tasks.title',  :order_direction => 'desc')

@options = {
        :conditions           => nil,
        :csv_file_name        => nil,
        :csv_field_separator => Defaults::CSV_FIELD_SEPARATOR,
        :custom_order         => {},
        :enable_export_to_csv => Defaults::ENABLE_EXPORT_TO_CSV,
        :group                => nil,
        :include              => nil,
        :joins                => nil,
        :name                 => Defaults::GRID_NAME,
        :order                => nil,
        :order_direction      => Defaults::ORDER_DIRECTION,
        :page                 => 1,
        :per_page             => Defaults::PER_PAGE,
        :saved_query          => nil,
        :total_entries        => nil,
        :with_paginated_resultset => nil,
        :with_resultset       => nil
      }

6、关联表的显示

Model:

class Project < ActiveRecord::Base  belongs_to :customer, :class_name => 'Company'  belongs_to :supplier, :class_name => 'Company'end

Controller:

@projects_grid = initialize_grid(Project, :include => [:customer, :supplier] )

View:

<%= grid(@projects_grid, :show_filters => :always) do |g|  g.column :name => 'Project Name', :attribute => 'name'  g.column  :name => 'Customer company', :model => 'Company', :attribute => 'name' do |task|    task.customer.name if task.customer  end  g.column  :name => 'Supplier company', :model => 'Company', :attribute => 'name', :table_alias => ' suppliers_projects' do |task|    task.supplier.name if task.supplier  endend -%>
