Sorry just dunno what exactly i should be posting as it seems bits are
needed in alot of places. i'll try and explain the basics.
my _line_item.html.erb file is as follows:
<% if line_item == @current_item %>
<tr id="current_item" >
<% else %>
<tr>
<% end %>
<td><%= line_item.quantity %>×</td>
<td><%= line_item.product.title %></td>
<td class="item_price" ><%= number_to_currency(line_item.total_price)
%></td>
</tr>
that takes in the information from the products table and displays said
product in the cart. my new table is user_products and i want if one of
these products chose to be displayed in cart also. im new to all this so
quite lost. i tried adding "<td><%= user_product.title %></td>" under
the line_item.product.title but it wouldnt run the page and returned an
NameError....undefined local variable or method `user_product' for #.
basically i dont know how to add in the new instance of a
user_product...should i be using if statement etc.
i have an add to cart button for user_products:
<%= button_to 'Add to Cart', line_items_path(:user_product_id =>
user_product),
:remote => true %>
but it says user_product is undefined.
in my line items controller i added user_products lines from what was
already there for product:
def create
@cart = current_cart
product = Product.find(params[:product_id])
@line_item = @cart.add_product(product.id)
user_product = UserProduct.find(params[:user_product_id])
@line_item = @cart.add_user_product(user_product.id)
respond_to do |format|
if @line_item.save
format.html { redirect_to(store_url) }
format.js { @current_item = @line_item }
format.xml { render :xml => @line_item,
:status => :created, :location => @line_item }
else
format.html { render :action => "new" }
format.xml { render :xml => @line_item.errors,
:status => :unprocessable_entity }
end
end
end
hope this is understandable. for user_products it was created using
scaffold so have separate controller,models etc then product.
