search for: category

I''ve tried pulling this together from examples in the book, searching the web and this list, but so far I''ve not been able to get it working just right. My table is a categories table with id and category fields. My form has the following: <td><%= select(''category'', ''category'', @categories = Category.find(:all, :order => "category").map {|cat| [cat.category, cat.category]}) %> I used [[cat.category, cat.category] as I am not interested...

hi, there :) Consider a blogging application whereby a user is trying to add a new blog. He/she has to select a category. Upon selecting a category from a drop down box, a new sub categories drop down box will be created (hence an AJAX call). Got this implemented and it''s ok. Now, let''s assume that a given blog can have multiple categories (and subcategories). For example, a blog on a restaurant re...

I''m writing a simple CMS where every item ("listing") HABTM categories and subcategories (which themselves belong_to a category).

...s it just render the template or should I have the instance variable as well also? I''ve tried changing it to redirect_to and it doesn''t error, but also doesn''t provide the error messages I want.

Hello, sorry for the bulk question, but I cannot find answer anywhere, I have model like Phonebook::Category, and i`m stuck on calling find() method on this model ?

Dear R-users, I want to fit a linear model with Y as response variable and X a categorical variable (with 4 categories), with the aim of comparing the basal category of X (category=1) with category 4. Unfortunately, there is another categorical variable with 2 categories which interact with x and I have to include it, so my model is s "reg3: Y=x*x3". Using fit.contrast to make the contrast (category 1 vs category 4) with options(contrasts=c("con...

I''ve got a model, "category" and another model "subcategory." Each subcategory belongs_to a category, and a category has_many subcategories.

This works : class Recipe < ActiveRecord::Base belongs_to :category end But (when I add validation) this does not work : class Recipe < ActiveRecord::Base belongs_to :category validates_length_of :category, :within => 6..20 validates_uniqueness_of :category, :message => "already exists" end thank you -- View this message in...

Hi there, I''ve been working on this for awhile and have finally decided to ask for a little guidance.I have a slight problem trying to save a selection. I have two models: A "Posting" has_many "Categories", and a "Category" belongs_to one "Posting". With that said, in the posting model I have "has_many :categories" and within the category model I have "belongs_to :posting". That part I ''believe'' is correct, however I very well could be off on that. The columns in...

I have categories and sub-categories in a table called "categories". Every row has a "parent" field to note if the entry is the sub-category of another (never goes deeper than 1 level). So there might be something like this: id | name | parent 1 Dog 0 2 Pug 1 3 Siamese 5 4 Shih Tzu 1 5 Cat 0 6 Wiener Dog 1 7 Persian 5 I''d like to list it like Dog --Pug --Shih Tzu --...

I really hope this is not a bad question (as in he''s abusing the list).

So, In the Position model...

...e tutorials and build a simple to-do list program with Items and Categories and have the related tables link up w/ the default "scaffold :Items" command plus custom defenitions. Then I erased all of that and tried rebuilding the program using the ruby script/generate scaffold Item (and category) command. Now the templates look like " <% for column in Item.content_columns %> <td><%=h item.send(column.name) %></td> <% end %> " And putting " <td><%h item.Category ? item.Category.name : "no category" %></td>...
