  • Sunspot / Solr full text search - how to index Rails associations

    - by Sam
    Is it possible to index through an association with Sunspot? For example, if a Customer has_many Contacts, I want a 'searchable' block on my Customer model that indexes the Contact#first_name and Contact#last_name columns for use in searches on Customer. acts_as_solr has an :include option for this. I've simply been combining the associated column names into a text field on Customer like shown below, but this doesn't seem very flexible. searchable do text :organization_name, :default_boost => 2 text :billing_address1, :default_boost => 2 text :contact_names do contacts.map { |contact| contact.to_s } end Any suggestions?

  • Issues with dynamically loading modules in code with Silverlight/Prism

    - by Greg Bailey
    In my Bootstrapper.cs in GetModuleCatalog, I need to specify the Module types using the typeof(ModuleType). In the example below I'm trying to load the Contact module on demand, but in order to get it into my module catalog, I need to have a reference to it in the project that holds my Bootstrapper. When I add a reference to Contact, then the Contact.dll gets added to the initial xap file, which defeats the purpose of loading the module dynamically. Am I missing something? Do you have to load the module catalog from a file to make this work? var catalog = new ModuleCatalog(); catalog.AddModule(typeof(Core)); catalog.AddModule(typeof(Contact), InitializationMode.OnDemand);

  • Need some advice on Core Data modeling strategy

    - by Andy
    I'm working on an iPhone app and need a little advice on modeling the Core Data schema. My idea is a utility that allows the user to speed-dial their contacts using user-created rules based on the time of day. In other words, I would tell the app that my wife is commuting from 6am to 7am, at work from 7am to 4pm, commuting from 4pm to 5pm, and home from 5pm to 6am, Monday through Friday. Then, when I tap her name in my app, it would select the number to dial based on the current day and time. I have the user interface nearly complete (thanks in no small part to help I've received here), but now I've got some questions regarding the persistent store. The user can select start- and stop-times in 5-minute increments. This means there are 2,016 possible "time slots" in week (7 days * 24 hours * 12 5-minute intervals per hour). I see a few options for setting this up. Option #1: One array of time slots, with 2,016 entries. Each entry would be a dictionary containing a contact identifier and an associated phone number to dial. I think this means I'd need a "Contact" entity to store the contact information, and a "TimeSlot" entity for each of the 2,016 possible time slots. Option #2: Each Contact has its own array of time slots, each with 2,016 entries. Each array entry would simply be a string indicating which phone number to dial. Option #3: Each Contact has a dictionary of time slots. An entry would only be added to the dictionary for time slots with an active rule. If a search for, say, time slot 1,299 (Friday 12:15pm) didn't find a key @"1299" in the dictionary, then a default number would be dialed instead. I'm not sure any of these is the "right" way or the "best" way. I'm not even sure I need to use Core Data to manage it; maybe just saving arrays would be simpler. Any input you can offer would be appreciated.

  • Jquery Accordion Close then Open

    - by Jon
    Hi Everyone, I've set up a number of accordions on a page using the jquery accordion plugin so I can implement expand all and collapse all functionality. Each ID element is it's own accordion and the code below works to close them all no matter which ones are already open: $("#contact, #address, #email, #sales, #equipment, #notes, #marketingdata") .accordion("activate", -1) ; My problem is with the expand all. When I have them all expand with this code: $("#contact, #address, #email, #sales, #equipment, #notes, #marketingdata") .accordion("activate", 0) ; Some will contract and some will expand based on whether or not they are previously open. My idea to correct this was to collapse them all and then expand them all when the expand all was clicked. This code however won't execute properly: $("#contact, #address, #email, #sales, #equipment, #notes, #marketingdata") .accordion("activate", -1) ; $("#contact, #address, #email, #sales, #equipment, #notes, #marketingdata") .accordion("activate", 0) ; It will only hit the second command and not close them all first. Any suggestions?

  • Binding a list belonging to another object in a custom model binder in ASP.NET MVC

    - by Dan
    I realize something like this has been asked, but this may be a little different Below is my Event object: Event : IEvent public int Id public string Title public List<EventContact> Contacts And EventContact: EventContact public int Id public string Name So, an Event has a list of EventContact' objects. Now, Event also implements IEvent - hence the custom model binder. I useIEventinstead of Event, so when the default model binder tries to do its thing, it lets me know it can't create anIEvent'. I have my view with populated with the contact info: <input type="text" name="contact[0].Name" value="DB Value"/> <input type="text" name="contact[1].Name" value="DB Value"/> <input type="text" name="contact[2].Name" value="DB Value"/> <!-- Event fields, etc --> So, in my custom model binder I am able to see all the value - sweet! The only thing is, I'm really not sure how to get all the contact fields and create a list of contacts from them, along with binding all the Event fields. Any and all help is appreciated!

  • How to lazy load scripts in YUI that accompany ajax html fragments

    - by Chris Beck
    I have a web app with Tabs for Messages and Contacts (think gmail). Each Tab has a Y.on('click') event listener that retrieves an HTML fragment via Y.io() and renders the fragment via node.setContent(). However, the Contact Tab also requires contact.js to enable an Edit button in the fragment. How do I defer the cost of loading contact.js until the user clicks on the Contacts tab? How should contact.js add it's listener to the Edit button? The Complete function of my Tab's on('click') event could serialize Get.script('contact.js') after Y.io('fragment'). However, for better performance, I would prefer to download the script in parallel to downloading the HTML fragment. In that case, I would need to defer adding an event listener to the Edit button until the Edit button is available. This seems like a common RIA design pattern. What is the best way to implement this with YUI? How should I get the script? How should I defer sections of the script until elements in the fragment are available in the DOM?

  • How do I best run a search on Date when it is not a :has_many association?

    - by Angela
    I have a number of activities that have a calculated scheduled date. The activities, for example, Email, have a email.days method which is the days from a Contact.start_date on which it should be sent. This means contact.start_date + email.days yields a date on which email is sent to contact. I would like to use link_to around the date, so I can see all the emails and associated contacts that are to be scheduled on that date. However, this "date" is not an attribute or an associate, so I'm not linking to a model's view. It's calculated. So: 1) What should the actual "format" of the date that gets passed in the URl be? What is the method to do the consistent conversion? 2) How do I (find) all instances, because this "date" is not an actual attribute, is it a calculated value which changes depending on the two associated models of Contact and Email. Thanks.

  • View bound to paged collection view not updating all of the time.

    - by Thomas
    I new to silverlight and trying to make a business application using the mvvm pattern and ria services. I have a view model class that contains a PagedCollectoinView and it is set to the item source of a datagrid. When I update the PagedCollectionView the datagrid is only updated the first time then after that subsequent changes to the data to not reflect in the view until after another edit. Things seem to be delayed one edit. Below is a summarized example of my xaml and code behind. This is the code for my view model public class CustomerContactLinks : INotifyPropertyChanged { private ObservableCollection<CustomerContactLink> _CustomerContact; public ObservableCollection<CustomerContactLink> CustomerContact { get { if (_CustomerContact == null) _CustomerContact = new ObservableCollection<CustomerContactLink>(); return _CustomerContact; } set { _CustomerContact = value; } } private PagedCollectionView _CustomerContactPaged; public PagedCollectionView CustomerContactPaged { get { if (_CustomerContactPaged == null) _CustomerContactPaged = new PagedCollectionView(CustomerContact); return _CustomerContactPaged; } } private TicketSystemDataContext _ctx; public TicketSystemDataContext ctx { get { if (_ctx == null) _ctx = new TicketSystemDataContext(); return _ctx; } } public void GetAll() { ctx.Load(ctx.GetCustomerContactInfoQuery(), LoadCustomerContactsComplete, null); } private void LoadCustomerContactsComplete(LoadOperation<CustomerContactLink> lo) { foreach (var entity in lo.Entities) { CustomerContact.Add(entity as CustomerContactLink); } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string propertyName) { if (PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } #endregion } Here is the basics of my XAML <Data:DataGrid x:Name="GridCustomers" MinHeight="100" MaxWidth="1000" IsReadOnly="True" AutoGenerateColumns="False"> <Data:DataGrid.Columns> <Data:DataGridTextColumn Header="First Name" Binding="{Binding Customer.FirstName}" Width="105" /> <Data:DataGridTextColumn Header="MI" Binding="{Binding Customer.MiddleName}" Width="35" /> <Data:DataGridTextColumn Header="Last Name" Binding="{Binding Customer.LastName}" Width="105"/> <Data:DataGridTextColumn Header="Address1" Binding="{Binding Contact.Address1}" Width="130"/> <Data:DataGridTextColumn Header="Address2" Binding="{Binding Contact.Address2}" Width="130"/> <Data:DataGridTextColumn Header="City" Binding="{Binding Contact.City}" Width="110"/> <Data:DataGridTextColumn Header="State" Binding="{Binding Contact.State}" Width="50"/> <Data:DataGridTextColumn Header="Zip" Binding="{Binding Contact.Zip}" Width="45"/> <Data:DataGridTextColumn Header="Home" Binding="{Binding Contact.PhoneHome}" Width="85"/> <Data:DataGridTextColumn Header="Cell" Binding="{Binding Contact.PhoneCell}" Width="85"/> <Data:DataGridTextColumn Header="Email" Binding="{Binding Contact.Email}" Width="118"/> </Data:DataGrid.Columns> </Data:DataGrid> <DataForm:DataForm x:Name="CustomerDetails" Header="Customer Details" AutoGenerateFields="False" AutoEdit="False" AutoCommit="False" CommandButtonsVisibility="Edit" Width="1000" Margin="0,5,0,0"> <DataForm:DataForm.EditTemplate> </DataForm:DataForm.EditTemplate> </DataForm:DataForm> And here is my code behind public Customers() { InitializeComponent(); BusyDialogIndicator.IsBusy = true; Loaded += new RoutedEventHandler(Customers_Loaded); CustomerDetails.BeginningEdit += new EventHandler(CustomerDetails_BeginningEdit); } void CustomerDetails_BeginningEdit(object sender, System.ComponentModel.CancelEventArgs e) { CustomerContacts.CustomerContactPaged.EditItem(CustomerDetails.CurrentItem); } private void Customers_Loaded(object sender, RoutedEventArgs e) { CustomerContacts = new CustomerContactLinks(); CustomerContacts.GetAll(); GridCustomers.ItemsSource = CustomerContacts.CustomerContactPaged; GridCustomerPager.Source = CustomerContacts.CustomerContactPaged; GridCustomers.SelectionChanged += new SelectionChangedEventHandler(GridCustomers_SelectionChanged); BusyDialogIndicator.IsBusy = false; } void GridCustomers_SelectionChanged(object sender, SelectionChangedEventArgs e) { CustomerDetails.CurrentItem = GridCustomers.SelectedItem as CustomerContactLink; } private void SaveChanges_Click(object sender, RoutedEventArgs e) { if (WebContext.Current.User.IsAuthenticated) { bool commited = CustomerDetails.CommitEdit(); if (commited && (!CustomerDetails.IsItemChanged && CustomerDetails.IsItemValid)) { CustomerContacts.Update(CustomerDetails.CurrentItem as CustomerContactLink); CustomerContacts.ctx.SubmitChanges(); CustomerContacts.CustomerContactPaged.CommitEdit(); CustomerContacts.CustomerContactPaged.Refresh(); (GridCustomers.ItemsSource as PagedCollectionView).Refresh(); } } }

  • Sending emails based on intervals using Ruby on Rails

    - by Angela
    Hi, I would like to be able to send a string of emails at a determined interval to different recipients. I assign to each Contact this series of Emails called a Campaign, where Campaign has Email1, Email2, etc. Each Contact has a Contact.start_date. Each Email has email.days which stores the number of days since a Contact's start-date to send the email. For example: Email1.days=5, Email2.days=7, Email3.days=11. Contact1.start_date = 4/10/2010; contact2.start_date = 4/08/2010 IF today is 4/15, then Contact1 receives Email 1 (4/15-4/10 = 5 days) IF today is 4/15, then Contact2 received Email 2 (4/15 - 4/8 = 7 days). What's a good action to run every day using a cron job that would then follow these rules to send out emails using ActionMailer? Thanks.

  • Auto increment with a Unit Of Work

    - by Derick
    Context I'm building a persistence layer to abstract different types of databases that I'll be needing. On the relational part I have mySQL, Oracle and PostgreSQL. Let's take the following simplified MySQL tables: CREATE TABLE Contact ( ID varchar(15), NAME varchar(30) ); CREATE TABLE Address ( ID varchar(15), CONTACT_ID varchar(15), NAME varchar(50) ); I use code to generate system specific alpha numeric unique ID's fitting 15 chars in this case. Thus, if I insert a Contact record with it's Addresses I have my generated Contact.ID and Address.CONTACT_IDs before committing. I've created a Unit of Work (amongst others) as per Martin Fowler's patterns to add transaction support. I'm using a key based Identity Map in the UoW to track the changed records in memory. It works like a charm for the scenario above, all pretty standard stuff so far. The question scenario comes in when I have a database that is not under my control and the ID fields are auto-increment (or in Oracle sequences). In this case I do not have the db generated Contact.ID beforehand, so when I create my Address I do not have a value for Address.CONTACT_ID. The transaction has not been started on the DB session since all is kept in the Identity Map in memory. Question: What is a good approach to address this? (Avoiding unnecessary db round trips) Some ideas: Retrieve the last ID: I can do a call to the database to retrieve the last Id like: SELECT Auto_increment FROM information_schema.tables WHERE table_name='Contact'; But this is MySQL specific and probably something similar can be done for the other databases. If do this then would need to do the 1st insert, get the ID and then update the children (Address.CONTACT_IDs) – all in the current transaction context.

  • JSP 2.0 SEO friendly links encoding

    Currently I have something like this in my JSP <c:url value="/teams/${contact.id}/${contact.name}" /> The important part of my URL is the ID, I just put the name on it for SEO purposes (just like stackoverflow.com does). I was just wondering if there is a quick and clean way to encode the name (change spaces per +, latin chars removal, etc). I'd like it to be like this: <c:url value="/teams/${contact.id}/${supercool(contact.name)}" /> Is there a function like that out there or should I make my own?

  • What should go in each MVVM triad?

    - by Harry
    OK, let's say I am creating a program that will list users contacts in a ListBox on the left side of the screen. When a user clicks on the contact, a bunch of messages or whatever appears in the main part of the window. Now my question is: how should the MVVM triads look? I have two models: Contact, and Message. The Contact model contains a list of Message models. Each ViewModel object will contain a single corresponding Model, right? And what about the Views? I have a "MainView" that is the main window, that will have things like the menu, toolbar etc. Do I put the ListBox in the MainView? My confusion is with what to put where; for example, what should the ContactView contain? Just a single instance of a contact? So the DataTemplate, ControlTemplate, context menus, styles etc for that single contact, and then just have a ListBox of them in the MainView...? Thanks.
