Validation for create action causing routing error - ruby-on-rails

Question

Validation for the create action are not working, I have made validation for the field to be present, but if I keep the fields empty and press submit, I get routing error, if I fill in the complete fields, It works perfectly fine. Also, the validation works perfectly fine for the update action.
Here is the view:
<%= stylesheet_link_tag 'gmaps4rails' %>
<%= form_for #estate, :html => { :class => 'form-horizontal',:multipart => true } do |f| %>
<% if #estate.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#estate.errors.count, "error") %> prohibited this estate from being saved:</h2>
<ul>
<% #estate.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<script>
function enableDisable(bEnable, textBoxID)
{
document.getElementById(textBoxID).disabled = !bEnable
}
</script>
<div class="control-group">
<%= f.label :Name, "Property/Tenant Name", :class => 'control-label' %>
<div class="controls">
<%= f.text_field :Name, :class => 'text_field', :placeholder => "e.g., Saxbys Coffee" %>
</div>
</div>
<div class="control-group">
<%= f.label :Address, :class => 'control-label' %>
<div class="controls">
<%= f.text_area :Address, :class => 'text_area', :cols => '10', :rows => '10', :placeholder => "e.g., 1236 36th Street NW Washington, DC 20007" %>
</div>
</div>
<div class="control-group">
<%= f.label :asset, "Upload Picture", :class => 'control-label' %>
<div class="controls">
<%= f.file_field :asset %>
</div>
</div>
<% if #estate.asset.present? %>
<div class="control-group">
<%= f.label "Delete Existing Picture", :class => 'control-label' %>
<div class="controls">
<%= f.check_box(:delete_asset) %>
</div>
</div>
<% end %>
<!-- <div class="control-group">
<%= f.label :Mgmt, "Would you like to share this property with your Real Estate Management Company?", :class => 'control-label' %>
<div class="controls">
<input type="checkbox" id="chkbox" onchange="document.getElementById('txtBox').disabled=!this.checked;" checked="checked" />
</div>
</div> -->
<% if current_user.Company.nil? %>
<div id="flip"><a>Would you like to share this property with your Management Company?</a></div>
<br />
<div id="panel">
<div class="control-group">
<%= f.label :Mgmt, "Company Name", :class => 'control-label' %>
<div class="controls">
<%= f.text_field :Mgmt, :class => 'text_field', :id => 'txtBox'%>
</div>
</div>
<div class="control-group">
<%= f.label :companyemail, "Company Email", :class => 'control-label' %>
<div class="controls">
<%= f.text_field :companyemail, :class => 'text_field', :id => 'txtBox'%>
</div>
</div>
</div>
<% end %>
<div class="form-actions">
<% if current_page?(controller:"estates", action:"edit", :id => params[:id] || 0)%>
<%= f.submit "Update Property Details", :class => 'btn btn-info' %>
<% else %>
<%= f.submit "Upload Property Details", :class => 'btn btn-info' %>
<% end %>
<% end %>
<script>
$(document).ready(function(){
$("#flip").click(function(){
$("#panel").slideToggle("slow");
});
});
</script>
Here is the controller:
def create
# #estate = Estate.new(params[:estate])
if current_user.Company.nil?
#estate = current_user.estates.build(params[:estate])
else
serve = User.find(##key)
#estate = Estate.new(params[:estate])
#estate.user_id = serve.id
#estate.Mgmt = current_user.Company
end
respond_to do |format|
if #estate.save
if current_user.Company.nil?
if #estate.companyemail = ''
#
else
EstateMailer.company_confirmation(#estate).deliver
end
end
format.html { redirect_to #estate, notice: 'Property details were successfully updated.' }
format.json { render json: #estate, status: :created, location: #estate }
else
format.html { render action: "new" }
format.json { render json: #estate.errors, status: :unprocessable_entity }
end
end
end
Error message:

Answer 1

after a little chat with Hrishikesh Sardar the bug was fixed, the problem was in if block of the create action:
if current_user.Company.nil?
#estate = current_user.estates.build(params[:estate])
else
serve = User.find(##key)
#estate = Estate.new(params[:estate])
#estate.user_id = serve.id
#estate.Mgmt = current_user.Company
end
this line:
#estate = current_user.estates.build(params[:estate])
had to be replaced by:
#estate = Estate.new(params[:estate])
#estate.user_id = current_user.id
somehow current_user.estates.new(params[:estate]) didn't worked, even if the relation between estate and user was built as required.
