search for: subcategory

I''ve got a model, "category" and another model "subcategory." Each subcategory belongs_to a category, and a category has_many subcategories. What I need to do is set it up so that I can search Category and Subcategory with one .find call. So: Category.find(:all, <etc) will find categories and subcategories. Now, I believe this can be done by...

I have a project I''m trying to decide if I want to use rails for. I''m new to rails, so I''m not sure how easy it would be to implement something like this using ActiveRecord. Here''s the situation: Category > subcategory > subcategory > product Category > subcategory > product Some categories will have many subcategories, others few. I want to use adjacency lists in the database like ID CATEGORY PARENT where top-level categories simply have no parent, but subcategories do. My concern is whe...

What I want to do is search categories for certain items, like so: @categories = Category.find(:all, :conditions => ["name LIKE ?", "#%{:search_string}%" and subcategories for the same: @subcategories = Subcategory.find(:all, :conditions => ["name LIKE ?", "#%{:search_string}%" Then I want to get @categories.listings, @subcategories.listings, merge them into @listings, sort them by once of their fields, and display them like so: <% for listing in @listings %> <%= rende...

...categories & subcategories: 1) "food" -> "fine dining" 2) "people" -> "lifestyle" 3) "travelling" -> "restaurants" After selecting a set of category and sub category, there will be a link entitled, "add another category/subcategory" (I guess this can be done with link_to_remote or something). My question is, how do you code it such that upon clicking on the link mentioned, another category drop down box will be displayed in the form. Selecting a category value would then cause a sub categories drop down box to appear in...

Hi, i was looking through the docs and couldn''t find a good clean solution for ordering a partial with an :order clause. say i was iterating over categories and thier corresponding sub-categories (regular belongs to) and wanted to order the subcategories according to a certain column; <% for category in @categories %> <% render: partial => ''sublist'',

...ies (from it''s two categories) as it wishes, and subcategories are displayed differently in both administration and display views. So what I have is: Class Listing < ActiveRecord::Base has_and_belongs_to_many :categories has_and_belongs_to_many :subcategories ... end Class Subcategory < ActiveRecord::Base has_and_belongs_to_many :listings belongs_to :categories end Class Category < ActiveRecord::Base has_and_belongs_to_many :listings has_many :subcategories ... end Is this allowed? I ask because I can''t create a listing with subcategories (from t...

I have a model, categories, and another model, subcategories. In my current code these have no connection except for the fact that categories has_many subcategories and a subcategory belongs_to a category. But by necessity, I need to change it so Subcategory extends Category; so that I can search both models with one command. I was hoping it would be as simple as changing Subcategory < ActiveRecord::Base to Subcategory < Category, but no such luck. Now I get the erro...

Hi, The current AliasAnalysis marks may-alias for cases when memory passed as function argument. i.e. void foo(int *A, int *B, int *C) { for (int i=0; i<N; i++) A[i] = B[i] + C[i]; } In the above example, it's may-alias for memory 'A', because 'A' is not known at 'foo' call sites. Alias analysis is able to figure out memory 'A' is no-alias, if I
