how can insert above erb code stored in string erb file below rendering (in pseud code) ?

  <table class="table table-striped">     <% erb_code = retrieve(chunk_of_erb_code)%>     <% erb_code here rendering %>    </table> 

is there solution problem? help.

update:

working code render inline (by kamesh):

<% erb_code = find_config_const('task_log_view', 'projectx')%> <%= render inline: erb.new(erb_code).result(binding) %> 

for practice, variable erb_code moved controller.

i think got question. can append html string in erb using in view:

<%= render inline:"<p>new field</p>"%> 

or

<%= render inline: "<% products.each |p| %><p><%= p.name %></p><% end %>" %> 

or in controller as:

render inline: "<% products.each |p| %><p><%= p.name %></p><% end %>" 

writing in _xyz.html.erb or xyz.html.erb , can used controller, well. more check following link. in sub topic - 2.2.6 using render :inline. rails guide

i have checked working of this. let me know in case of issue.
