How to find instance of an object in a collection within a collection in rails I'm trying to write an if statement that will find an instance of an object in a collection within another collection... House has_many :occupants Occupant has_many :shirts belongs_to :house Shirt belongs_to :occupant So if I want check if any of the occupants of house own a white shirt, I want to do something like this: <% if @house.occuptants.shirts.where(:color => 'white') %> However when I do that I get an error: undefined method `shirts' for #< Occupant::ActiveRecord_Associations_CollectionProxy I believe because occupants is a collection in this case, but I'm not sure what the correct approach or syntax should be. 2 Answers 2 Something simpler and that will help you later for different use cases is to add more to the relationships: class House has_many :occupants has_many :shirts,...

Why is character in string not mutated? def test_problem(str) str[3].upcase! # str[3] = str[3].upcase! works str end p test_problem("hello") My question is why String.upcase! which is mutating method doesn't mutate string in a case above but you need to reassign that character in string? 2 Answers 2 String# returns a new string, as is documented. String# a = "foo" a.object_id # => 70217975553640 a[0].object_id # => 70217957574840 A string is not composed of character objects, it is a single object (at least on a superficial level, I'm not sure of the C internals). So there is no way to extract a character and still have it belong to the original string - you need to work with the string as a whole if you want to mutate it. String#= on the other hand does mutate the string String#= You could make your method like so: def test_problem(str) str[3] = str[3].upca...

In Ruby, why is it not enough to alias `method_missing` to catch call to undefined methods? That seems all the more unexpected when defining a dummy method passing all arguments do the job. That is the following works: def method_missing(ago, *lokatoj, &bloko) mistrafe(ago, *lokatoj, &bloko) end def mistrafe(ago, *lokatoj, &bloko) # faru ion end While the following doen't alias mistrafe method_missing Why is that so? 1 Answer 1 alias mistrafe method_missing does not work because the syntax of alias is: alias mistrafe method_missing alias alias OLD_NAME NEW_NAME That said, the following will work: alias method_missing mistrafe By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to th...

Finding posts under a category name keyword with pg_search on Rails 5 I'm using gem pg_search and doing multi-search for Website and Post tables. I am able to search by records title, but I also want to be able to search records based on categories they belong to. pg_search So, for example, when I type "typographic" (category name) to search input, all Website and Post records under that category should be listed, as well as all records that have "Typographic" in the title. I think it can be done with association but I could not make it work 🤷‍♂️ _header.html.erb <%= form_tag search_index_path, method: :get do %> <%= text_field_tag :query, params[:query], placeholder: "Search" %> <% end %> search_controller.rb class SearchController < ApplicationController def index @pg_search_result = PgSearch.multisearch(params[:query]) end end models/post.rb class Post < ApplicationRecord include PgSearch multisearchable :ag...
