Rails exporting xls using link_to format - ruby-on-rails

Question

Hello everybody who likes RAILS, i have a problem i'm trying to export by "ejecutive_id" to XLS but i'm not doing the correct code,
-I created a select box where i can select all my ejecutives.
-I created another select box where i can select by status_id.
-I selected 1 ejecutive for example "Mogan" (ejecutive_id = 1)
-I selected 1 status form example "active" (status_id = 0 )
-After selecting both select boxes i click on "SEARCH"
-After doing SEARCH i'm getting my results (#list_policies this value in my code is before respond format)
Here is my controller
****PROJECT/APP/CONTROLLER/policy_managment/policy.rb********
class PolicyManagement::PolicyController < ApplicationController
def generate_print_ejecutive_comercial
#search_ejecutive = params[:search_ejecutive]
#search_status = params[:status_id]
#list_ejecutives_comision = Ejecutive.find(:all)
#list_policies_search = Policy.deleted_is(0)
if params[:search_ejecutive].to_i!=0
#list_policies_search = #list_policies_search.ejecutive_id_is(#search_ejecutive)
end
if !params[:status_id].blank?
if params[:status_id].to_i != 3
#list_policies_search = #list_policies_search.state_is(params[:status_id])
end
else
#list_policies_search = #list_policies_search.state_is(0)
end
#status_id = params[:status_id]
if !#search_dependent_dni.blank?
if #list_dependents.blank?
#list_dependents = Dependent.id_gt(0)
end
#list_dependents = #list_dependents.num_document_is(#search_dependent_dni)
list_dependencies = []
#list_dependents.each do |dependent|
list_dependency_dependents = Dependency.find(:all, :conditions => { :dependent_id => dependent.id })
list_dependency_dependents.each do |dependency|
list_dependencies << dependency
end
end
policy_ids = []
list_dependencies.each do |dependency|
policy_ids << dependency.policy_id.to_i
end
end
#list_policies_search = #list_policies_search.deleted_is(0)
#list_policies = #list_policies_search.paginate(:page => params[:page], :per_page => 10)
#results = #list_policies_search.find(:all,:conditions=> { :ejecutive_id => #search_ejecutive })
respond_to do |format|
format.html
format.xls
format.js {
render :update do |page|
page.replace_html 'table', :partial => 'table2'
end
}
end
end
end
Here maybe could be the problem,also those are my links where i can export
*********HERE IS MY VIEW***********
<% form_remote_tag :url=>{:action=>"generate_print_ejecutive_comercial"},:before=>"load_close('loading_search')",:success=>"load_off('loading_search')" do -%>
<label>EJECUTIVES:</label>
<%= select_tag 'search_ejecutive',"<option value=\"\">Select</option>"+options_for_select(#list_ejecutives_comision.collect {|t| [t.name.to_s+" "+t.lastname1.to_s,t.id]})%>
</span>
<label>STATUS :</label>
<%= select_tag "status_id","<option value=\"3\">ALL</option>"+options_for_select([["active",0],["cancel",1],["no cancel ",2]],0) %>
</span>
<input name="Buscar" value="SEARCH" type="submit" /><span id="loading_search"></span>
<% end %>
#HERE WITH THOSE LINKS I'M EXPORTING ONLY MY FIRST 10 VALUES
<%= link_to("Export Excel","http://localhost:3000/policy_management/policy/generate_print_ejecutive/generate_print_ejecutive_comercial.xls")%>
<%= link_to "Export XLS",:controller=>"policy_management/policy",:action=>"generate_print_ejecutive_comercial",:format=>"xls" %>
<%= link_to 'PRINT PDF', :controller=>"policy_management/policy",:action=>"generate_print_ejecutive_comercial", :format=>"pdf" %>
I'm exporting my partial view and it depends of this
#list_policies = #list_policies_search.paginate(:page => params[:page], :per_page => 10)
Here is my partial view and i'm using #list_policies
********************PARTIAL VIEW THAT I WANT TO EXPORT*********
<table>
<% #list_policies.each do |policy| %>
<tr>
<td><div class="nobreak"><%= policy.num_policy%></div></td>
<td><div class="nobreak">
<% if !policy.ejecutive.blank? %>
<%= policy.ejecutive.name %><%= policy.ejecutive.lastname1 %><%= policy.ejecutive.lastname2 %>
<% end %></div>
</td>
<td><div class="nobreak"><%= policy.str_state%></div></td>
</tr>
</table>
Seems that i need to add some params to my links_to....format.... i don't know what to add
Somebody can check this code?

It seems like using an options hash to dynamically build your query might be easier / cleaner. I would do it like this:
class PolicyManagement::PolicyController < ApplicationController
def generate_print_ejecutive_comercial
#list_ejecutives_comision = Ejecutive.find(:all)
policy_options = {:deleted => false}
policy_options = policy_options.merge({:ejecutive_id => params[:search_ejecutive]}) unless params[:search_ejecutive].blank?
policy_options = policy_options.merge({:state => params[:status_id]}) unless params[:status_id].blank? and (params[:status_id] != 3)
#list_policies_search = Policy.all(policy_options)
if !#search_dependent_dni.blank?
if #list_dependents.blank?
#list_dependents = Dependent.id_gt(0)
end
#list_dependents = #list_dependents.num_document_is(#search_dependent_dni)
list_dependencies = []
#list_dependents.each do |dependent|
list_dependency_dependents = Dependency.find(:all, :conditions => { :dependent_id => dependent.id })
list_dependency_dependents.each do |dependency|
list_dependencies << dependency
end
end
policy_ids = []
list_dependencies.each do |dependency|
policy_ids << dependency.policy_id.to_i
end
end
#list_policies = #list_policies_search.paginate(:page => params[:page], :per_page => 10)
respond_to do |format|
format.html
format.xls
format.js {
render :update do |page|
page.replace_html 'table', :partial => 'table2'
end
}
end
end
end
