Actually, params[:cart] is derived from <%form_for :cart ...%> Inside
this, there are textfields corresponding to "carts" table and hence I
could save the values in the form and I'm doing this way:
CONTROLLER:
def add_to_cart
@cart_items=[]
@cart=find_cart(params[:cart])
if @cart.save
@cart_items << @cart
else
flash[:notice]="Details couldn't be saved"
end
end
private
def find_cart(cartobj)
session[:cart] ||= Cart.new(cartobj)
end
I'm using @cart_items array just because I couldn't iterate through the
@cart to list all the entered details in the add_to_cart.rhtml as:
VIEW:
<h1>Your details:</h1>
<ul>
<%for item in @cart_items%>
<li><%=item.campsite%></li>
<li><%=item.arrival_date%></li>
<li><%=item.nights%></li>
<li><%=item.parents%></li>
<li><%=item.children%></li>
<li><%=item.family_claim%></li>
<%end%>
</ul>
<%=button_to "Empty cart", :action => :empty_cart%>
So, now when I click the "add to cart" button in the view everything
gets added to the "carts" table and I'm taken to add_to_cart.rhtml with
the list of details. Now in this case how can i empty it when empty_cart
action is triggered for this specific session?
thanks fred.
