I am trying to implement a related article on the user current page. I am not using sunspot or anything like that. I have tried this code by Uchenna Okafor but i get an error.
In the model i have
#Related Search
def self.related_search(query, join = "AND")
find(:all, :conditions => related_search_conditions(query, join))
end
def self.related_search_conditions(query, join)
query.split(/\s+/).map do |word|
'(' + %w[name instructions].map { |col| "#{col} LIKE #{sanitize('%' + word.to_s + '%')}" }.join(' OR ') + ')'
end.join(" #{join} ")
end
On the show.html.erb i have
<%= @recipe.related_search %>
My error message is
NoMethodError in Recipes#show
Showing /Users/sigidis/Ruby/food/app/views/recipes/show.html.erb where line #129 raised:

Looks like you may be confusing an instance method with a class method. I don't know how you are creating @recipe
, but try removing the self
in self.related_search
and self.related_search_conditions
.
EDIT:
Ok, I think I understand a bit more. First, I'm assuming those methods are in your recipe.rb
model and you have surrounded them with a class Recipe
and end
. Second, @recipe
has no definition. So use Recipe
instead to refer to the class. Lastly, your methods require at least the first argument to be passed, in this case the search query. So try the following: Recipe.related_search("QUERY HERE")
.
