WiceGrid 3.6.0.pre4 examples

Text filters with negation

negation: true adds a checkox to a text filter. The checked checkbox is the logical NOT - it changes the semantics of a text filter to not showing all records with a matching substring.

    class NegationController < ApplicationController
      def index
        @tasks_grid = initialize_grid(Task,
          include: [:priority, :status, :project],
          order: 'statuses.name',
          custom_order: {
            'tasks.priority_id' => 'priorities.name',
            'tasks.status_id'   => 'statuses.position',
            'tasks.project_id'  => 'projects.name'
          }
        )
      end
    end
    
  • <%= grid(@tasks_grid) do |g|
    
      g.column name:  'ID', attribute: 'id', filter: false
    
      g.column name:  'Title', attribute: 'title', negation: true

        task.priority.name if task.priority
