Hello, On a command: rake db:migrate I get the "rake aborted!" error. The message is: No Rakefile found (looking for: rakefile, Rakefile, rakebile.rb, Rakefile.rb) c:/InstantRails/ruby/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:1822:in ''load_rakefile'' Checking my setup, I see that Rakefile.rb is in the expected path.

I am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

Hello, I have the usual Categories and Products table scenario, mediated by a Categories_Products join table. When I create a new Product and into a given Category, I notice that my join table is not being populated. Shouldn''t the join Categories_Products table be populated?

Hello, I generated a controller, using the command: ruby script/generate controller my_kontroller my_model The generated controller file, however, contains an empty class definition.

I am working on an Rails application that uses a pretty complex category structure through out the site. I have defined a table to house all the info and a FK to reference parents within the table CREATE TABLE categories ( id int(11) NOT NULL auto_increment, name varchar(50) NOT NULL, parent_id int(11) default NULL, constraint fk_category_id foreign key (category_id) references

Hi, Which user-authentication plugins should one try first? Too many out there and too little time to try them all fairly. Thanks for your recommendation. cheers! -- Posted via http://www.ruby-forum.com/.

With most models, almost always I find myself writing Search/Find actions. When I view a Listing of a model, I want to look at another record or set of records. How nice it would be if I can do a query-by-example while viewing a Listing, or during Show/Edit/Create. Would be nice if Search becomes another act in the scaffolding magic. This wish has been expressed here before. Since then, has

Hello, The following view: <%= start_form_tag %> Enter term to find <p> <%= text_field_tag :name, params[:name] %> </p> <%= link_to "Find", { :action => ''find_term''} %> <%= end_form_tag %> does not appear to pass back the value of :name to the action: def find_term term =

I just switched from using the standard "id" column into using my own primary key and generating my own unique id for each record. But, this breaks acts_as_tree. Because my new primary key is not an integer, it breaks the SQL query as follows: StatementInvalid in PagesController#create --------------------------------------------------------------------------------------

I need an ordered (sortable tree) and I just was thinking if somehting like this is possible: class Item< ActiveRecord::Base acts_as_tree :order => "position" acts_as_list :scope => ''parent_id = #{self.id}'' end For my understanding mixing of two acts_as should be p?ssible, at least in this case, right? Unfortunatly the :scope is not working, I am not

Hi, The user/login management system in Chapter 31: Authenticating Your Users and Chapter 32: Authorizing Users with Roles of Chad Fowler''s Rails Recipes looks reasonable and adequate. However, when I ran the Chapter 31 code, I get the following error: Username or password invalid And I am not even given the chance to sign in; that is, the signin form does not appear at all. Has

I''m just getting used to using HABTM structures. Something I''m trying to do now is create a site that has "sections" each section then could have a sub "section". So I built a "sections" table and in the model I included the line "has_and_belongs_to_many :sections" I also made a table called "sections_sections" to build the

Guys, I''m having a problem getting acts_as_tree working. It seems from the Agile book (p. 255) that acts_as_tree only supports one-to-one record relations, whereas I need many-to-many support. In other words, looking at the picture at the top of page 256 where where only 1 id is linked to 1 parent_id, I need multiple id''s linked to multiple parent_id''s - for

Hi, I''m trying to implement password confirmation, based on the Agile example, but just can''t make any progress. User DB has these fields: ========================= t.column :name, :string, :limit => 40 t.column :hashed_password, :string t.column :salt, :string User model has: =============== attr_accessor :password_confirmation

Basically, I''m trying to have a table called "categories" have a many to many relationship with itself. But I also want each catagory to be able to be "copied" into another category so it is essentially a child category to more than one parent. To me the obvious way of doing this is by creating another table called category_maps (and a model called CategoryMap).

hi. base from the cookbook example, where each categories can have many recipes, id like the categories to have multiple sub categories, unlimited levels. please show some code, as i am new to Ruby and Ruby On Rails. thanks -- Posted via http://www.ruby-forum.com/.

So I have the following model class Topic < ActiveRecord::Base belongs_to :topic has_many :topics, :order => :position acts_as_tree :order => :position acts_as_list :scope => :topic_id end that I use for a site''s navigation. Everything (list, create, edit, even the drag&drop sort) works fine, except the destroy function, which the vanilla version def destroy

Hi, If I have a db table categories - id - name - parent_id - position is it alright to have the Category model act_as_tree and for each level act_as_list? class Category < ActiveRecord::Base acts_as_tree :order => :position acts_as_list :scope => :parent_id end Thanks, Peter

Hi, I''m using the latest gem version of rails under MacOS Tiger. I was trying to use acts_as_tree as described in the rails book. So I have something like: class Category < ActiveRecord::Base acts_as_tree :order => "title" end create table categories ( id int not null auto_increment, title
