Hi All, I have a problem with upgrade samba on Solaris 10 (x86). The current version is 3.0.25b (distributed with Solaris 10). I am trying to upgrade version to 3.4.5. I compiled samba from sources, has not any problem with make and installation. Now I have 2 different versions and when I am running "svcadm enable samba" I am receiving old version. The old version installed under:

In my mind, it should work like this: <%= select ''item'', ''category_ids'', Category.find(:all).collect {|c| [c.name, c.id] }, {}, {:multiple=>true, :size=>20} %> Then Rails should automatically populate and update HABTM on that. As it is now, the above won''t work (I created a getter in item''s model that returns an array of

Postgres database. I have a categories table, with two columns id, and name. I have a recipes table, with a category_ids column. I want each recipe to belong to one or more category. in recipe_controller.rb I have this: def create @recipe = Recipe.new( @params[''recipe''] ) @recipe.category_ids = @params[''recipe''][''category_ids''].map{

I''m having some trouble with an instance variable being read as nil in my app. I have an image uploading, that can be added to categories. The page loads up initially fine, and if I upload an image without errors everything works fine. I''m working on the validation, but with the code I have if their are validation errors it renders ''new'' again, but reads

I''m working on a simple CMS. The main data type are "listings" a listing habtm (has_and_belongs_to_many) categories and subcategories. Subcategories belong_to categories. Subcategories are basically the same as categories, but they are treated differently in a few situations. The problem is, I can''t seem to write the view/controller/model code that allows me to

I have: <%= form_for(@supplier) do |f| %> ....... ...... <%= render ''sector_categories'', :locals => {:f => f} %> in _sector_categories partial I have: <div class="field"> <div id="category_update"> <% for category in @categories %> <%= f.check_box :category_ids[], category.id,

i think there ara two ways of relate products and categories , basically i want to fix one product(e.g hp dv7....) to some categories (notebook,17"notebooks...) i made a table named categorization(incuding category_id,product_id fields) then in models i write these codes below class Product < ActiveRecord::Base has_many :categories, :through => :categorizations

Hi there, I have a question on what would be the best way to save a HABTM model. A posting habtm categories, and a category habtm postings. class Category < ActiveRecord::Base has_and_belongs_to_many :postings end class Posting < ActiveRecord::Base has_and_belongs_to_many :categories end In my blog_controller, where the actual posting is saved, is where I think I''m

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 making

I''m working with a similar model in Episode 73, (my scenario is editing multiple pictures for a product using attachment_fu). And I''m getting an error when I try the technique suggested: ./views/admin/_form.rhtml <% for picture in product.pictures %> <% fields_for "product[picture_attributes][]", picture do | picture_form| %> Title: <%=

Hello List, I''m a bit spent on this problem, and my code might be whack. I seem to be encountering a problem where the primary key on a join table is not being resolved correctly. I will elaborate after some code bits. I am creating the join table using migrations, and relevant model code is this: class Post < ActiveRecord::Base has_and_belongs_to_many :records

Hello folks! Beare with me for a second, while I explain my problem. Assuming we have the trivial model of class Author has_many :books end class Book end How do people go about creating the authors/edit and authors/new views if you want to be able to add and remove arbitrary amount of Books at Author creation and edit time? What I mean by this is that I go to

I am doing the recipe/category example, but with a has_many_and_belongs_to relationship. To select categories for a recipe, I have a select control. When editing, I want the proper categories selected. In order to get it to work, I put this in my _form.rhtml: <select id="recipe_categories" name="recipe[category_ids][]" size="4" multiple> <%=

When a user creates a post I also want to save all the tags associated with it. I do that in the post_controller like this presently: def save @post = Post.new(@params[:post]) @tags = Tag.new(@params[:tags]) @post.user_id = session[:id] if @post.save @tags.title.split('','').each do |tag| present_tag = Tag.find_by_title(tag.strip) present_tag =

I am trying to find a DVD iso that is not a torrent, and looking through the mirrors I am unable to find one. Does anyone happen to have a mirror or repository that they know of that carries the DVD iso for direct download? I am behind a pretty strict firewall and am unable to do torrents. Thanks in advance Michael Weiner =================================== Please consider the environment

The Problem ----------- After using a join in my find the id attributes set in my Entity objects are wrong! It is setting the Entity id to the value from Postcode id! The Code -------- entities = Entity.find(:all, :conditions => [...omited...], :joins => "as e inner join postcodes as pc on substring_index(e.postcode,'' '', 1) =

Dear all, I have an n x n matrix of p-values. The matrix is symmetrical, as it describes the "each against each" p values of correlation coefficients. How can I best correct the p values of the matrix? Notably, the total number of the tests performed is n(n-1)/2, since I do not test the correlation of each variable with itself. That means, I only want to correct one half of the matrix,

Dear list readers - it was brought to my attention that during the upgrade of a server to rh7.2, and selecting the ext3 migration works well with 1 exception that i need verified if i could please. i heard that once you migrate to ext3, you may no longer do a kernel upgrade without downgrading to ext2 and then putting the kernel or AC kernel in place 'patched'. What i need to know

Dear all, I am having troubles importing values written as scientific notation using read.table(). I'm sure this is a frequent problem, as many people in my lab have this problem as well, so I'm sure that I just have troubles googling for the right solution. The problem is, that, given a file like that: a 1 2e-4 b 2 3e-8 ... the third column gets imported as a factor, or a string if I

Dear all, I am writing a vignette that requires a file which I am not allowed to distribute, but which the user can easily download manually. Moreover, it is not possible to download this file automatically from R: downloading requires a (free) registration that seems to work only through a browser.
