this entry.coffee.js datepicker is..

jquery -> $('#leave_start').datepicker({ mindate: 0 }); $('#leave_end').datepicker({ mindate: 0 });

this view...

%table.table.table-bordered.table-striped{:style => 'table-layout:fixed; width:100% !important;'} %th.lt leave start: %td.lt= f.text_field :leave_start, :label => false, :id => 'leave_start', :input_html => {:value => ''} %td.lt= f.error :leave_start, :class => 'er' %table.table.table-bordered.table-striped{:style => 'table-layout:fixed; width:100% !important;'} %th.lt leave end: %td.lt= f.text_field :leave_end, :label => false, :id => 'leave_end', :input_html => {:value => ''} %td.lt= f.error :leave_end, :class => 'er' %table.table.table-bordered.table-striped{:style => 'table-layout:fixed; width:100% !important;'} %th.lt amount of days: %td.lt= f.text_field :range_days, :label => false, :id => 'range_days', :input_html => {:value => ''} %td.lt= f.error :range_days, :class => 'er' %table.table.table-bordered.table-striped{:style => 'table-layout:fixed; width:100% !important;'} = f.button :submit, "submit", :class => 'btn btn-primary', :style => 'margin-left:50px;'
