  • Nested form child only updates if parent changes.

    - by chap
    In this video (10 sec) you can see that the nested attribute is only updated if it's parent model is changed. Using rails 3.0.0.beta and full project is on github.

  • What is the difference between type and type.__new__ in python?

    - by Jason Baker
    I was writing a metaclass and accidentally did it like this: class MetaCls(type): def __new__(cls, name, bases, dict): return type(name, bases, dict) ...instead of like this: class MetaCls(type): def __new__(cls, name, bases, dict): return type.__new__(cls, name, bases, dict) What exactly is the difference between these two metaclasses? And more specifically, what caused the first one to not work properly (some classes weren't called into by the metaclass)?

  • FORTRAN: determine variable type

    - by tibbs

  • problems with build params for accepts_nested_attributes_for

    - by holden
    I'm trying to add the user_id to a nested attribute that gets built by a parent controller but it doesn't seem to have the desired effect? Ie. I have a model called Place.rb which accepts_nested_attributes_for :reviews The nested attribute works fine and I build it inside the Places controller like so... @review = @place.reviews.build(:user_id => current_user.id) I was previously adding the user thru the form, but would like to do it thru the controller so that it only adds the user_id on creation, as it might get updated by someone else and i don't want the update changing the user_id... old way which works: <%= e.label :content, "Review" %><br /> <%= e.text_area :content, :rows => 20, :class => 'jquery_ckeditor' %><br /> <%= e.hidden_field :user_id, :value => current_user.id %> but thru the controller the build method with options has no effect? Any ideas? Can I not do this thru the build?

  • Dynamically specify the type in C#

    - by Lirik
    I'm creating a custom DataSet and I'm under some constrains: I want the user to specify the type of the data which they want to store. I want to reduce type-casting because I think it will be VERY expensive. I will use the data VERY frequently in my application. I don't know what type of data will be stored in the DataSet, so my initial idea was to make it a List of objects, but I suspect that the frequent use of the data and the need to type-cast will be very expensive. The basic idea is this: class DataSet : IDataSet { private Dictionary<string, List<Object>> _data; /// <summary> /// Constructs the data set given the user-specified labels. /// </summary> /// <param name="labels"> /// The labels of each column in the data set. /// </param> public DataSet(List<string> labels) { _data = new Dictionary<string, List<object>>(); foreach (string label in labels) { _data.Add(label, new List<object>()); } } #region IDataSet Members public List<string> DataLabels { get { return _data.Keys.ToList(); } } public int Count { get { _data[_data.Keys[0]].Count; } } public List<object> GetValues(string label) { return _data[label]; } public object GetValue(string label, int index) { return _data[label][index]; } public void InsertValue(string label, object value) { _data[label].Insert(0, value); } public void AddValue(string label, object value) { _data[label].Add(value); } #endregion } A concrete example where the DataSet will be used is to store data obtained from a CSV file where the first column contains the labels. When the data is being loaded from the CSV file I'd like to specify the type rather than casting to object. The data could contain columns such as dates, numbers, strings, etc. Here is what it could look like: "Date","Song","Rating","AvgRating","User" "02/03/2010","Code Monkey",4.6,4.1,"joe" "05/27/2009","Code Monkey",1.2,4.5,"jill" The data will be used in a Machine Learning/Artificial Intelligence algorithm, so it is essential that I make the reading of data very fast. I want to eliminate type-casting as much as possible, since I can't afford to cast from 'object' to whatever data type is needed on every read. I've seen applications that allow the user to pick the specific data type for each item in the csv file, so I'm trying to make a similar solution where a different type can be specified for each column. I want to create a generic solution so I don't have to return a List<object> but a List<DateTime> (if it's a DateTime column) or List<double> (if it's a column of doubles). Is there any way that this can be achieved? Perhaps my approach is wrong, is there a better approach to this problem?

  • Nested forms and automatic creation of parent, children

    - by Karen
    Guys, I was wondering if it was possible to create new parent, children in a has many relationship, using rails nested forms. Rails documentation clearly says that this works in a one to one relationship. Not sure if its the same in has many relationship. For example: If params = { :employee => { :name => "Tester", :account_attributes => {:login => 'tester'} } } works as one to one relationship. So Employee.new(params) works fine. New employee, account are created. Supposing I had params = { :employee => { :name => "Tester", :account_attributes => { "0" => {:login => 'tester'}, "1" => {:login => 'tester2'} } } } Employee.new(params) doesnt work. It fails on child validations saying parent cant be blank. Any help is appreciated. Thanks Karen

  • Nested Object Forms not working as expected

    - by Craig Walker
    I'm trying to get a nested model forms view working. As far as I can tell I'm doing everything right, but it still does not work. I'm on Rails 3 beta 3. My models are as expected: class Recipe < ActiveRecord::Base has_many :ingredients, :dependent => :destroy accepts_nested_attributes_for :ingredients attr_accessible :name end class Ingredient < ActiveRecord::Base attr_accessible :name, :sort_order, :amount belongs_to :recipe end I can use Recipe.ingredients_attributes= as expected: recipe = Recipe.new recipe.ingredients_attributes = [ {:name=>"flour", :amount=>"1 cup"}, {:name=>"sugar", :amount=>"2 cups"}] recipe.ingredients.size # -> 2; ingredients contains expected instances However, I cannot create new object graphs using a hash of parameters as shown in the documentation: params = { :name => "test", :ingredients_attributes => [ {:name=>"flour", :amount=>"1 cup"}, {:name=>"sugar", :amount=>"2 cups"}] } recipe = Recipe.new(params) recipe.name # -> "test" recipe.ingredients # -> []; no ingredient instances in the collection Is there something I'm doing wrong here? Or is there a problem in the Rails 3 beta?

  • nested include in php

    - by aeonsleo
    The directory structure: C:/wamp/www/application/model/data_access/data_object.php C:/wamp/www/application/model/users/user.class.php C:/wamp/www/application/controller/projects.php C:/wamp/www/application/controller/links/links.php I have 2 php files data_object.php and user.class.php Now user.class.php has an include statement for data_object.php wchih is relative to user.class.php.These two files are under different directory hierarchy. Now I have to include this user.class.php in various files (like projects.php, links.php-which themselves are under different hierarchy) whenever i want to create a User() object. The problem is the relative path for file inclusion of data_object.php does work for say projects.php but if i open links.php the error message says it could not open file data_object.php in user.class.php. What i think is for relative inclusion of data_object.php it is considering the path of the file in which user.class.php is included. I am facing such problems in more than one scenarios I have to keep my directory structure the way it is but have to find a way to work with nested includes. I used Document root of session it give root path as C:/wamp/www/ i appended the path for data_object.php include but this is not working. (note: the forward slash is present after www) I am currently running on wamp server's localhost but after completion i have to host the solution on a domain. Pls help

  • MySQL nested set hierarchy with foreign table

    - by Björn
    Hi! I'm using a nested set in a MySQL table to describe a hierarchy of categories, and an additional table describing products. Category table; id name left right Products table; id categoryId name How can I retrieve the full path, containing all parent categories, of a product? I.e.: RootCategory > SubCategory 1 > SubCategory 2 > ... > SubCategory n > Product Say for example that I want to list all products from SubCategory1 and it's sub categories, and with each given Product I want the full tree path to that product - is this possible? This is as far as I've got - but the structure is not quite right... select parent.`name` as name, parent.`id` as id, group_concat(parent.`name` separator '/') as path from categories as node, categories as parent, (select inode.`id` as id, inode.`name` as name from categories as inode, categories as iparent where inode.`lft` between iparent.`lft` and iparent.`rgt` and iparent.`id`=4 /* The category from which to list products */ order by inode.`lft`) as sub where node.`lft` between parent.`lft` and parent.`rgt` and node.`id`=sub.`id` group by sub.`id` order by node.`lft`

  • Problem with Railscast #197 - Nested Model Form Part 2

    - by sscirrus
    I'm trying to implement Ryan's Railscast #197 in a system with Questions, Answers, and (multiple choice) Options. http://railscasts.com/episodes/197-nested-model-form-part-2. I have successfully implemented the nesting among these forms/partials. The simpler 'check box' way to delete records works properly. The problem occurs when I try to add/delete records. I have copied the code exactly as it appears in his Railscast: #new.html.erb <%= javascript_include_tag :defaults, :cache => true %> <% f.fields_for :in_options do |builder| %> <%= render "option_fields", :f => builder %> <% end %> #_option_fields.html.erb partial <%= f.hidden_field :_destroy %> <%= link_to_function "remove", "remove_fields(this)" %> #application_helper.rb (exact same as #197) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end #application.js (exact same as #197. I have an Event.addbehavior below this code.) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } 2 problems: When I click on the 'remove' link it doesn't remove - it just shifts the page up or down. When I include link_to_add_fields "Add Answer", f, :answers, I get undefined method `klass' for nil:NilClass. Thanks everyone.

  • Problem accessing variable in a nested form partial

    - by brad
    I have a nested form in a rails view that is called like this <% f.fields_for :invoice_item_numbers do |item_no_form| %> <%= render 'invoice_item_number', :f => item_no_form %> <% end %> and the partial (_invoice_item_number.html.erb) looks like this <div class='invoice_item_numbers'> <% if f.object.new_record? %> <li><%= f.label :item_number %><%= f.text_field :item_number %> <%= link_to_function "remove", "$(this).parent().remove()", :class => 'remove_link' %></li> <% else %> <li class="inline"><%= f.label :item_number %><%= f.text_field :item_number %> </li><li class="inline"><%= f.label :description %><%= invoice_item_number.description %></li><li><%= f.label :amount %><%= f.text_field :amount %> <%= f.check_box '_destroy', :class => 'remove_checkbox' %> <%= f.label '_destroy', 'remove', :class => 'remove_label' %></li> <% end %> </div> This fails with the error message undefined method `description' for nil:NilClass Why does invoice_item_number return a nil object in this partial? It is obviously being defined somehow because if I change it to something else (e.g. item_number.description then the error message becomes undefined local variable or methoditem_number' for #instead. The invoice_item_number object that is being displayed by this partial is being used perfectly well by the form helpers as<%= f.text_field :item_number %and<% f.text_field :amount %both work perfectly well. I have tried a number of solutions such as using@invoice_item_number` and explicitly defining an object in the render method but these have not worked. Presumably there is a very simple answer to this.

  • Is nested synchronized block necessary?

    - by Dan
    I am writing a multithreaded program and I have a method that has a nested synchronized blocks and I was wondering if I need the inner sync or if just the outer sync is good enough. public class Tester { private BlockingQueue<Ticket> q = new LinkedBlockingQueue<>(); private ArrayList<Long> list = new ArrayList<>(); public void acceptTicket(Ticket p) { try { synchronized (q) { q.put(p); synchronized (list) { if (list.size() < 5) { list.add(p.getSize()); } else { list.remove(0); list.add(p.getSize()); } } } } catch (InterruptedException ex) { Logger.getLogger(Consumer.class.getName()).log(Level.SEVERE, null, ex); } } } EDIT: This isn't a complete class as I am still working on it. But essentially I am trying to emulate a ticket machine. The ticket machine maintains a list of tickets in the BlockingQueue q. Whenever a client adds a ticket to the machine, the machine also keeps track of the price of the last 5 tickets (ArrayList list)

  • How to render all records from a nested set into a real html tree

    - by Christoph Schiessl
    I'm using the awesome_nested_set plugin in my Rails project. I have two models that look like this (simplified): class Customer < ActiveRecord::Base has_many :categories end class Category < ActiveRecord::Base belongs_to :customer # Columns in the categories table: lft, rgt and parent_id acts_as_nested_set :scope => :customer_id validates_presence_of :name # Further validations... end The tree in the database is constructed as expected. All the values of parent_id, lft and rgt are correct. The tree has multiple root nodes (which is of course allowed in awesome_nested_set). Now, I want to render all categories of a given customer in a correctly sorted tree like structure: for example nested <ul> tags. This wouldn't be too difficult but I need it to be efficient (the less sql queries the better). Update: Figured out that it is possible to calculate the number of children for any given Node in the tree without further SQL queries: number_of_children = (node.rgt - node.lft - 1)/2. This doesn't solve the problem but it may prove to be helpful.

    hey guys, i am trying to create a spreadsheet which automagically gives a grade to a student based on their marks they got. I've apparently hit excels nested IF statement limit which is 7. here's my if statement: =IF(O5>0.895,"A+",IF(O5>0.845,"A",IF(O5>0.795,"A-",IF(O5>0.745,"B+",IF(O5>0.695,"B",IF(O5>0.645,"B-",IF(O5>0.595,"C+",IF(O5>0.545,"C","D")))))))) I was reading online that I could create a VBA script and assign it that, but I dont know anything about VBA....so if someone could help me write a VBA for this, would be awesome. Its still mising the C- grade and anything lower should be awarded a D mark. This is the grading scheme I am trying to create...: A+ 89.500 - 100.000 Pass with Distinction A 84.500 - 89.490 Pass with Distinction A- 79.500 - 84.490 Pass with Distinction B+ 74.500 - 79.490 Pass with Merit B 69.500 - 74.490 Pass with Merit B- 64.500 - 69.490 Pass with Merit C+ 59.500 - 64.490 Pass C 54.500 - 59.490 Pass C- 49.500 - 54.490 Pass D 0.000 - 49.490 Specified Fail I wouldn't mind going down the VBA route, however my understanding of VB language is absolutely minimal (don't like it)...if this gets too tedious, I was thinking to create a small php/mysql application instead.

  • Use jQuery's dataTable plugin with a nested Ajax call

    - by mrr0ng
    I am trying to use a nested ajax call to populate a table, and once the table is built, use jQuery's dataTable plugin to pretty it up. The problem I am running into is an order of operations question. When do I call the dataTable function so that I can be assured that the table is built AFTER the values are populated? When I try the following code, the dataTable is created before the rows are built. <script type="text/javascript"> $(document).ready(function() { $.ajax({ url:"http://totalrockregistration.com/feeds/bands.php", dataType:"jsonp", success: function(jsonData){ $.each(jsonData.bands, function(i,bands){ if (bands.barID == "<?php echo $_GET["barID"]; ?>"){ var songIdFromBandJson = bands.song; var bandNameFromJson = bands.name; var bandScoreFromJson = bands.score; $.ajax({ url:"http://totalrockregistration.com/feeds/songs.php", dataType:"jsonp", success: function(songsJsonData){ $.each(songsJsonData.songs, function(i,songs){ if (songIdFromBandJson == songs.id){ var songName=(songs.name); $("#leaderBoardTable tbody").append("<tr><td>"+bandNameFromJson+"</td><td>"+bandScoreFromJson+"</td><td>"+songName+"</td></tr>"); } }); } }); } }); makeLeaderTable(); }, }); function makeLeaderTable(){ $('#leaderBoardTable').dataTable({ "aaSorting": [[ 1, "desc" ]], "iDisplayLength": 50 }); } }); </script>

  • Sorting nested set by name while keep depth integrity

    I'm using the nested set model that'll later be used to build a sitemap for my web site. This is my table structure. create table departments ( id int identity(0, 1) primary key , lft int , rgt int , name nvarchar(60) ); insert into departments (lft, rgt, name) values (1, 10, 'departments'); insert into departments (lft, rgt, name) values (2, 3, 'd'); insert into departments (lft, rgt, name) values (4, 9, 'a'); insert into departments (lft, rgt, name) values (5, 6, 'b'); insert into departments (lft, rgt, name) values (7, 8, 'c'); How can I sort by depth as well as name? I can do select replicate('----', count(parent.name) - 1) + ' ' + node.name , count(parent.name) - 1 as depth , node.lft from departments node , departments parent where node.lft between parent.lft and parent.rgt group by node.name, node.lft order by depth asc, node.name asc; However, that does not match children with their parent for some reason. department lft rgt --------------------------- departments 0 1 ---- a 1 4 ---- d 1 2 -------- b 2 5 -------- c 2 7 As you can see, department 'd' has department 'a's children!

  • Rails Nested Attributes Doesn't Insert ID Correctly

  • Reflection and changing a variables type at runtime?

    Hi I'm trying to create an object Of a specific type. I've got the following code, but it fails because it can't cast the new table object to the one that is already defined. I need table to start of an IEnumerable type so I can't declare is an object. Public sub getTable(ByVal t as Type) Dim table As Table(Of Object) Dim tableType As Type = GetType(Table(Of )).MakeGenericType(t) table = FormatterServices.GetUninitializedObject(tableType) End sub So in short - is there a way of changing a variable type at runtime? (or a better way of doing what I'm doing) Thanks in advance. James

  • Scala method where type of second parameter equals part of generic type from first parameter

    - by ifischer
    I want to create a specific generic method in Scala. It takes two parameters. The first is of the type of a generic Java Interface (it's from the JPA criteria query). It currently looks like this: def genericFind(attribute:SingularAttribute[Person, _], value:Object) { ... } // The Java Interface which is the type of the first parameter in my find-method: public interface SingularAttribute<X, T> extends Attribute<X, T>, Bindable<T> Now i want to achieve the following: value is currently of type java.lang.Object. But I want to make it more specific. Value has to be the of the same type as the placeholder "_" from the first parameter (and so represents the "T" in the Java interface). Is that somehow possible, and how? BTW Sorry for the stupid question title (any suggestions?)
