So I'm doing some basic validation and trying to add an arbitrary key to the flash hash (you can do that right?)
So in my controller I have this... "previousaction" posts to this page.
if params[:home_value] == "Select One"
flash.now[:home_value] = "Please select a home value"
render "previousaction"
else
#set controller vars.. render this action as normal
end
And in the view:
<% if home_value %>
<h6 id="notice" style="color:red;padding-bottom:5px;"><%= home_value %></h6>
<%= label_tag "Estimated Home Value", "Estimated Home Value", :style => "color:red;"%><br/>
<% else %>
<%= label_tag "Estimated Home Value", "Estimated Home Value" %><br/>
<% end %>
But I get this error when trying开发者_JAVA技巧 to load the controller action (the first time):
undefined local variable or method `home_value'
Tips appreciated :)
For Dave:
In a previous action/view I use flash[:notice] like this:
if params[:zip_code].length != 5
flash.now[:notice] = "Invalid zipcode. Please enter your 5-digit zipcode"
render "firstpage"
else
and then in the view
<% if notice %>
Is flash[:notice] a special flash key for rails?
home_value
won't magically be associated with the flash
, it's just being treated as a local variable; try accessing the flash hash with :home_value
directly.
That said, what's the purpose of using an arbitrary key?
