Hi,
I am trying to call a controller method from my view, but I get an error
and I don't know how to correct it.
What i am trying to do:
I am in the edit form of the model Product, and products can have many
ingredients. So on my edit form there is a text_field where you type the
ingredient with a link "Add" which is supposed to add the typed
ingredient to the current ingredients list.
this is how i try to call my controller method:
<%=link_to "Add",:action => :add_ingredient,:id => @product %>
This is my method in the controller:
def add_ingredient
if @product.id.blank?
@product = Product.find(params[:id])
end
@product.ingredients <<
Ingredient.find_or_create_by_name(params[:search])
@product.update_attributes(params[:product])
end
The error:
Unknown action
No action responded to 30. Actions: add_ingredient, create, destroy,
edit, index, new, show, and update
the url:
http://localhost:3000/products/30/add_ingredient
Thanks
Greg
