in my own library "w2tags", I create a wrap(I call it a hot tag
"-user_path"), and it will expand on erb
inside file 'include.w2erb'
~~~~~~~~~~~~~~~~~~~~~~~~~~~
!H! _user_path
-if permitted_to? :manage, :users
%li= link_to "Users", users_path
source 'index.w2erb'
~~~~~~~~~~~~~~~~~~~~
!inc!include.w2erb
-user_path
How about principle "DRY-UP the view"
inside file 'include.w2erb'
~~~~~~~~~~~~~~~~~~~~~~~~~~~
!H!_each2
- $0.each_with_index do |$0|
-end
!H! _td
-each2 @rec;r,i
%tr.pop-up-show{pop="#grid-pop-edit" class="d r<%=i+1%>"}
~^%td $0
^.c1.c;.c2;.c3;.c4;.c5;.c6;.c7;.c8;.c9;.c10= $*
source 'index.w2erb'
~~~~~~~~~~~~~~~~~~~~
!inc!include.w2erb
%table
-td i+1 ; r[:cus_code] ; r[:cus_name] ; r[:cus_type]
#page.h{page=<%= @page%>}
OR you can code like this
%table
-td i+1;\
r[:cus_code];\
r[:cus_name];\
r[:cus_type]
#page.h{page=<%= @page%>}
OR...
%table
- @rec.each_with_index do |$0|
%tr.pop-up-show{pop="#grid-pop-edit" class="d r<%=i+1%>"}
%td.c1.c= i+1
%td.c2= r[:cus_code]
%td.c3= r[:cus_name]
%td.c4= r[:cus_type]
- end
#page.h{page=<%= @page%>}
if you refresh your browser it will parse and generate 'index.erb'
result 'index.erb'
~~~~~~~~~~~~~~~~~~
<table>
<% @rec.each_index do |r,i| %>
<tr class="pop-up-show" pop="#grid-pop-edit" class="d r<%=i+1%>">
<td class="c1 c"><%= i+1 %></td>
<td class="c2"><%= r[:cus_code] %></td>
<td class="c3"><%= r[:cus_name] %></td>
<td class="c4"><%= r[:cus_type] %></td>
</tr>
<% end %>
</table>
<div id="page" class="h" page=<%= @page%>>
