Redirect to same page using Rails 3 - ruby

Question

I need after user's action complete the page should exactly remain same using Rails 3.I am explaining my code and code flow below.
home.html.erb:
<div class="col-md-6" style="float:none; margin:auto;">
<%= form_for :sdf ,:url => {:action => "scan_report" },:html => {:id =>"form-id" } ,remote: true do |f| %>
<% if params[:receipt_no] %>
<div class="input-group bmargindiv1 col-md-12"> <span class="input-group-addon text-left">Receipt No. Scan :</span>
<%= f.text_field :Receipt_No,:class => "form-control", :value => params[:receipt_no],:id => "scan-field",:onfocus => ("$('#rcd_btn').submit()") %>
</div>
<% else %>
<div class="input-group bmargindiv1 col-md-12"> <span class="input-group-addon text-left">Receipt No. Scan :</span>
<%= f.text_field :Receipt_No,:class => "form-control",placeholder:"Receipt No. scan" %>
</div>
<% end %>
<%= f.submit "Submit",:id => "rcd_btn",:style => "display:none;" %>
<% end %>
<div class="clearfix"></div>
</div>
<div class="block block-themed" style="display:none" id="whole-div6" >
<div class="block-title">
<div class="block-options">
<i class="fa fa-arrow-down"></i>
</div>
<h4>Wood Slip</h4>
</div>
<div id="wood-puri">
</div>
</div>
From the above form when user will put the receipt no,lets say 150325006/1 and pressing enter key the below page will display.
_wood.html.erb:
<div class="block-content" style="display:none;">
<div class="timeline-container">
<div class="input-group bmargindiv1 col-md-6 pull-left"><span class="input-group-addon text-left"><div class="leftsidetextwidth">Receipt No :</div></span>
<input type="text" class="form-control" value= "<%= #sdf.Receipt_No %>">
</div>
<div class="input-group bmargindiv1 col-md-6 pull-left"><span class="input-group-addon text-left"><div class="leftsidetextwidth">Date & Time :</div></span>
<input type="text" class="form-control" value= "<%= #sdf.Created_On %>">
</div>
<div class="input-group bmargindiv1 col-md-6 pull-left"><span class="input-group-addon text-left"><div class="leftsidetextwidth">Deceased Name :</div></span>
<input type="text" class="form-control" value= "<%= #hcsy.Deceased_Name %>">
</div>
<div class="input-group bmargindiv1 col-md-6 pull-left"> <span class="input-group-addon text-left"><div class="leftsidetextwidth">Donor Name :</div></span>
<input type="text" class="form-control" value= "<%= #sdf.Doner_Name %>">
</div>
<div class="input-group bmargindiv1 col-md-12 pull-left"> <span class="input-group-addon text-left"><div class="leftsidetextwidth">Amount :</div></span>
<input type="text" class="form-control" value= "<%= #woods.Amount %>">
</div>
<div class="clearfix"></div>
</div>
<div class="block block-themed themed-asphalt">
<div class="block-title"><h5>Office Use</h5></div>
<div class="block-content full">
<%= form_for :vendor,:url => {:action =>"payment" } do |f| %>
<div class="totalaligndiv">
<div class="input-group bmargindiv1 col-md-6" style="margin:auto; float:none;"><span class="input-group-addon text-left"><div class="leftsidetextwidth">Select Vendor :</div></span>
<%= f.select(:v_name,options_for_select(Vendor.where(s_catagory: "Woods").pluck(:v_name),selected: "Select vender name"),{},{:class => "form-control",:prompt => 'Selected Vendor'}) %>
</div>
<div class="totalaligndiv">
<%= f.hidden_field :receipt_no, :value => #sdf.Receipt_No %>
</div>
<div class="totalaligndiv">
<%= f.hidden_field :amount,:value => #woods.Amount %>
</div>
<div class="totalaligndiv">
<%= f.hidden_field :date,:value =>#sdf.Created_On %>
</div>
<div class="clearfix"></div>
<div class="tbpaddingdiv1 text-center">
<%= f.submit "Add to Payment",:class => "btn btn-success" %>
</div>
<div class="clearfix"></div>
</div>
<% end %>
</div>
</div>
</div>
From the above page user will select one vendor name when user will click on submit button the db operation will happen and user will stay on the same page which was displaying before(i.e-user will stay on that _woods.html.erb page also after submit) submit button pressed and the "Add to Payment" vanishes till the next receipt no scan.My controller file is given below.
homes_controller.rb:
class HomesController < ApplicationController
def home
#sdf=TSdf.new
respond_to do |format|
format.html
format.js
end
end
def scan_report
if #sdf=TSdf.find_by_Receipt_No(params[:sdf][:Receipt_No])
#hcsy=THcsy.find_by_Sdp_Id(#sdf.Sdp_Id)
#hcsy_deatils=THcsyDetails.find_by_HCSY_ID(#hcsy.id)
#woods=THcsyFundTypeMaster.find_by_Fund_Type_Code(1)
#burn=THcsyFundTypeMaster.find_by_Fund_Type_Code(2)
#good=THcsyFundTypeMaster.find_by_Fund_Type_Code(3)
#swd=THcsyFundTypeMaster.find_by_Fund_Type_Code(5)
#photo=THcsyFundTypeMaster.find_by_Fund_Type_Code(6)
#vendor=Vendor.new
flash[:notice]=" number matched"
else
splitted = params[:sdf][:Receipt_No].split('/')
receipt = splitted[0]
table_id = splitted[1]
#sdfs=TSdf.find_by_Receipt_No(receipt)
if #sdfs
#hcsys=THcsy.find_by_Sdp_Id(#sdfs.Sdp_Id)
#fund_details=THcsyFundTypeMaster.find_by_Fund_Type_Code(table_id)
else
flash[:notice]="Scan number not found"
end
end
end
def payment
#adds=THcsyFundTypeMaster.find_by_Amount(params[:vendor][:amount])
#vendor=PaymentVendor.create(:Receipt_No => params[:vendor][:receipt_no],:c_date => Date.today.to_time_in_current_zone,:v_date => params[:vendor][:date],:v_amount => params[:vendor][:amount],:v_catagory => #adds.Fund_Type_Name,:v_name => params[:vendor][:v_name],:v_status => "No" )
if #vendor
flash[:notice]="Vendor added the payment"
flash[:color]="valid"
redirect_to :action => "home"
else
flash[:alert]="vendor could not added the payment"
flash[:color]="invalid"
render 'home'
end
end
end
scan_report.js.erb:
<% if #fund_details.Fund_Type_Name=="Woods" %>
$("#whole-div6").css("display", "block");
$("#wood-puri").html("<%= escape_javascript (render 'woods' ) %>");
$("#wood-puri").slideDown(350);
<% end %>
Here inside payment action now i am redirecting home page .But i need user will stay on that rendered _wood.html.erb: page after click on add to payment button.Please help me.

Answer 1

Did you tried :back? i.e. in controller
respond_to do |format|
format.html { redirect_to :back }
end
It will redirect to the page from where request was arrived.
