    - by devnet247
    Hi all New to wpf and therefore struggling a bit. I am putting together a quick demo before we go for the full implementation I have a treeview on the left with Continent Country City structure when a user select the city it should populate some textboxes in a tabcontrol on the right hand side I made it sort of work but cannot make it work with composite objects. In a nutshell can you spot what is wrong with my zaml or code. Why is not binding to a my CityDetails.ClubsCount or CityDetails.PubsCount?

  • Nested ComboBox doesn't update source by selection.

    - by Shimmy
    Hello. I am using a ComboBox bound under a DataContext: <tk:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox ItemsSource="{Binding Source={StaticResource CategoriesCollection}" DisplayMemberPath="Title" SelectedItem="{Binding Category}" /> </DataTemplate> </tk:DataGridTemplateColumn.CellEditingTemplate> When the row is initiated the value of Category is null. Once I select the first value in the ComboBox it sets it up. But when I select another value, it doesn't get changed.

  • RSpec mocking a nested model in Rails - ActionController problem

    - by emson
    Hi All I am having a problem in RSpec when my mock object is asked for a URL by the ActionController. The URL is a Mock one and not a correct resource URL. I am running RSpec 1.3.0 and Rails 2.3.5 Basically I have two models. Where a subject has many notes. class Subject < ActiveRecord::Base validates_presence_of :title has_many :notes end class Note < ActiveRecord::Base validates_presence_of :title belongs_to :subject end My routes.rb file nests these two resources as such: ActionController::Routing::Routes.draw do |map| map.resources :subjects, :has_many => :notes end The NotesController.rb file looks like this: class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @subject = Subject.find(params[:subject_id]) @note = @subject.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to(@subject) } end end end Finally this is my RSpec spec which should simply post my mocked objects to the NotesController and be executed... which it does: it "should create note and redirect to subject without javascript" do # usual rails controller test setup here subject = mock(Subject) Subject.stub(:find).and_return(subject) notes_proxy = mock('association proxy', { "create!" => Note.new }) subject.stub(:notes).and_return(notes_proxy) post :create, :subject_id => subject, :note => { :title => 'note title', :body => 'note body' } end The problem is that when the RSpec post method is called. The NotesController correctly handles the Mock Subject object, and create! the new Note object. However when the NoteController#Create method tries to redirect_to I get the following error: NoMethodError in 'NotesController should create note and redirect to subject without javascript' undefined method `spec_mocks_mock_url' for #<NotesController:0x1034495b8> Now this is caused by a bit of Rails trickery that passes an ActiveRecord object (@subject, in our case, which isn't ActiveRecord but a Mock object), eventually to url_for who passes all the options to the Rails' Routing, which then determines the URL. My question is how can I mock Subject so that the correct options are passed so that I my test passes. I've tried passing in :controller = 'subjects' options but no joy. Is there some other way of doing this? Thanks...

  • Getting hierarchy data from a self-referencing table

    - by Emanuil
    Let's say you have the following table: items(item_id, item_parent) ... and it is a self-referencing table as item_parent refers to item_id. What SQL query would you use to SELECT all items in the table along with their depth where the depth of an item is the sum of all parents and grand parents of that item. If the following is the content of the table: item_id item_parent ----------- ----------- 1 0 2 0 3 2 4 2 5 3 ... the query should retrieve the following set of objects: {"item_id":1,"depth":0} {"item_id":2,"depth":0} {"item_id":3,"depth":1} {"item_id":4,"depth":1} {"item_id":5,"depth":2} P.S. I'm looking for a MySQL supported approach.

  • Can MySQL Nested Select return list of results

    - by John
    Hi I want to write a mysql statement which will return a list of results from one table along with a comma separated list of field from another table. I think an example might better explain it Table 1 ======================== id First_Name Surname ---------------------- 1 Joe Bloggs 2 Mike Smith 3 Jane Doe Table 2 ======================== id Person_Id Job_id --------------------- 1 1 1 2 1 2 3 2 2 4 3 3 5 3 4 I want to return a list of people with a comma separated list of job_ids. So my result set would be id First_Name Surname job_id ------------------------------ 1 Joe Bloggs 1,2 2 Mike Smith 2 3 Jane Doe 3,4 I guess the sql would be something like select id, First_Name, Surname, (SELECT job_id FROM Table 2) as job_id from Table 1 but obviously this does not work so need to change the '(SELECT job_id FROM Table 2) as job_id' part. Hope this makes sense Thanks John

  • Synchronization of Nested Data Structures between Threads in Java

    - by Dominik
    I have a cache implementation like this: class X { private final Map<String, ConcurrentMap<String, String>> structure = new HashMap...(); public String getValue(String context, String id) { // just assume for this example that there will be always an innner map final ConcurrentMap<String, String> innerStructure = structure.get(context); String value = innerStructure.get(id); if(value == null) { synchronized(structure) { // can I be sure, that this inner map will represent the last updated // state from any thread? value = innerStructure.get(id); if(value == null) { value = getValueFromSomeSlowSource(id); innerStructure.put(id, value); } } } return value; } } Is this implementation thread-safe? Can I be sure to get the last updated state from any thread inside the synchronized block? Would this behaviour change if I use a java.util.concurrent.ReentrantLock instead of a synchronized block, like this: ... if(lock.tryLock(3, SECONDS)) { try { value = innerStructure.get(id); if(value == null) { value = getValueFromSomeSlowSource(id); innerStructure.put(id, value); } } finally { lock.unlock(); } } ... I know that final instance members are synchronized between threads, but is this also true for the objects held by these members? Maybe this is a dumb question, but I don't know how to test it to be sure, that it works on every OS and every architecture.

  • CoffeeScript Class Properties Within Nested Anonymous Functions

    - by Aric
    I'm just taking a look at CoffeeScript for the first time so bare with me if this is a dumb question. I'm familiar with the hidden pattern methodology however I'm still wrapping my head around object prototypes. I'm trying to create a basic class for controlling a section on my site. The problem I'm running into is losing defined class variables within a different scope. For example, the code below works fine and creates the properties within the object perfectly. However when I jump into a jQuery callback I lose all knowledge of the class variables storing some of the jQuery objects for multiple uses. Is there a way to grab them from within the callback function? class Session initBinds: -> @loginForm.bind 'ajax:success', (data, status, xhr) -> console.log("processed") return @loginForm.bind 'ajax:before', (xhr, settings) -> console.log @loader // need access to Session.loader return return init: -> @loginForm = $("form#login-form") @loader = $("img#login-loader") this.initBinds() return

  • Create a HTML table from nested maps (and vectors)

    - by Kenny164
    I'm trying to create a table (a work schedule) I have coded previously using python, I think it would be a nice introduction to the Clojure language for me. I have very little experience in Clojure (or lisp in that matter) and I've done my rounds in google and a good bit of trial and error but can't seem to get my head around this style of coding. Here is my sample data (will be coming from an sqlite database in the future): (def smpl2 (ref {"Salaried" [{"John Doe" ["12:00-20:00" nil nil nil "11:00-19:00"]} {"Mary Jane" [nil "12:00-20:00" nil nil nil "11:00-19:00"]}] "Shift Manager" [{"Peter Simpson" ["12:00-20:00" nil nil nil "11:00-19:00"]} {"Joe Jones" [nil "12:00-20:00" nil nil nil "11:00-19:00"]}] "Other" [{"Super Man" ["07:00-16:00" "07:00-16:00" "07:00-16:00" "07:00-16:00" "07:00-16:00"]}]})) I was trying to step through this originally using for then moving onto doseq and finally domap (which seems more successful) and dumping the contents into a html table (my original python program outputed this from a sqlite database into an excel spreadsheet using COM). Here is my attempt (the create-table fn): (defn html-doc [title & body] (html (doctype "xhtml/transitional") [:html [:head [:title title]] [:body body]])) (defn create-table [] [:h1 "Schedule"] [:hr] [:table (:style "border: 0; width: 90%") [:th "Name"][:th "Mon"][:th "Tue"][:th "Wed"] [:th "Thur"][:th "Fri"][:th "Sat"][:th "Sun"] [:tr (domap [ct @smpl2] [:tr [:td (key ct)] (domap [cl (val ct)] (domap [c cl] [:tr [:td (key c)]]))]) ]]) (defroutes tstr (GET "/" ((html-doc "Sample" create-table))) (ANY "*" 404)) That outputs the table with the sections (salaried, manager, etc) and the names in the sections, I just feel like I'm abusing the domap by nesting it too many times as I'll probably need to add more domaps just to get the shift times in their proper columns and the code is getting a 'dirty' feel to it. I apologize in advance if I'm not including enough information, I don't normally ask for help on coding, also this is my 1st SO question :). If you know any better approaches to do this or even tips or tricks I should know as a newbie, they are definitely welcome. Thanks.

  • best way to parse plain text file with a nested information structure

  • Iterating through nested dictionaries

    - by Framester
    I want to write an iterator for my 'toy' Trie implementation. Adding already works like this: class Trie: def __init__(self): self.root = dict() pass def add(self, string, value): global nops current_dict = self.root for letter in s: nops += 1 current_dict = current_dict.setdefault(letter, {}) current_dict = current_dict.setdefault('value', value) pass The output of the adding looks like that: trie = Trie() trie.add("hello",1) trie.add("world",2) trie.add("worlds",12) print trie.root {'h': {'e': {'l': {'l': {'o': {'value': 1}}}}}, 'w': {'o': {'r': {'l': {'d': {'s': {'value': 2}, 'value': 2}}}}}} I know, that I need a __iter__ and next method. def __iter__(self): self.root.__iter__() pass def next(self): print self.root.next() But AttributeError: 'dict' object has no attribute 'next'. How should I do it? [Update] In the perfect world I would like the output to be one dict with all the words/entries with their corresponding values.

  • Shorthand for nested null checking C#

    - by Myster
    As far as I know there is not a significantly more elegant way to write the following.... string src; if((ParentContent!= null) &&(ParentContent.Image("thumbnail") != null) &&(ParentContent.Image("thumbnail").Property("src") != null)) src = ParentContent.Image("thumbnail").Property("src").Value Do you think there should be a C# language feature to make this shorter? And if so, what should it look like? for example, something like extending the ?? operator string src = ParentContent??.Image("thumbnail")??.Property("width")??.Value; Apologies for the rather contrived example, and my over-simplified solution.

  • Thoughts on a Shoutbox anyone?

    - by sologhost
    I'm wanting to create a shoutbox, though I'm wondering if there is another way to go about this rather than using setInterval to query the database for new shouts every number of seconds. Honestly, I don't like having to go about it this way. Seems a bit redundant and repetitive and just plain old wrong. Not to mention the blinking of the shouts as it grabs the data. So I'm wondering on how the professionals do this? I mean, I've seen shoutboxes that work surperb and doesn't seem to be using any setInterval or setTimeout javascript functions to do this. Can anyone suggest any ideas or an approach to this that doesn't use setInterval or setTimeout?? Thanks :)
