Form fields cleared out because of validation


#1

Hi there

Implementing my first “update” procedure worked fine.
I took this as a template for a “create” procedure, but that does not
work as expected: when I enter invalid data, the validation stops me
from saving the data, that’s working, but all fields are cleared!

Furthermore, also the data is not saved, no error message is dislayed.

Advice is more then welcome!

Controller Code:

def create_client
case request.method
when :get
@client = Client.new
when :post
client = Client.new(params[:client])
if client.save true
flash[:notice] = “Client successfully added”
redirect_to({:controller => ‘client’, :action => ‘overview’},
true)
else
flash[:errobj] = ‘client’
end
end
end

Layout Code

<% if flash[:errobj] -%>
<%= error_messages_for flash[:errobj] -%>
<% end %>

Okay, I am an idiot. But there is still hope because I found out
myself.

Instead of

  client = Client.new(params[:client])

I should have said

  @client = Client.new(params[:client])

Layout Code

<% if flash[:errobj] -%>
<%= error_messages_for flash[:errobj] -%>
<% end %>

If things aren’t working the way you expected, debug your code, write
tests, etc.

<%= debug flash[:errobj] %>
<%= flash.inspect %>

Or, get a little acquainted with ruby-debug and just throw a <%
debugger -%> in there.

Flash messages survive a request, like a redirect, but are not
available in the current request. Since you just render the same
template on invalid models, use flash.now[:errobj], or @errobj.
