  • How to validate a ComboBox programatically?

    - by PhOeNiX

The following is my combobox in model : DataGridTemplateColumn dataGridComboBoxTemplateColumnObj = new DataGridTemplateColumn(); dataGridComboBoxTemplateColumnObj.Header = column.Header; FrameworkElementFactory comboBoxFactory = new FrameworkElementFactory(typeof(ComboBox)); Binding bindingItemSourceObj = new Binding(column.ItemsSourcePropertyName); comboBoxFactory.SetValue(ComboBox.HorizontalAlignmentProperty, HorizontalAlignment.Stretch); comboBoxFactory.SetValue(ComboBox.ItemsSourceProperty, bindingItemSourceObj); comboBoxFactory.SetValue(ComboBox.SelectedValuePathProperty, column.ValuePropertyName); dataGridComboBoxTemplateColumnObj.CellTemplate = new DataTemplate(); dataGridComboBoxTemplateColumnObj.CellTemplate.VisualTree = comboBoxFactory;

  • Zend Framework: Autoloading module resources in config.ini?

    - by Olagato
    Is it possible, to configure the following behaviour in application.ini? <?php class Bootstrap extends Zend_Application_Bootstrap_Bootstrap { protected function _initAdminModuleAutoloader() { $this->_resourceLoader = new Zend_Application_Module_Autoloader(array( 'namespace' => 'Admin', 'basePath' => APPLICATION_PATH . '/modules/admin', )); $this->_resourceLoader->addResourceTypes(array( 'model' => array( 'namespace' => 'Model', 'path' => 'models' ) )); } } ?> If so, can you please show us an example? Thanks.

  • First Call to a Controller, Constant is defined, Second call, "uninitialized constant Oauth"?

    - by viatropos
    I am trying to get the OAuth gem to work with Rails 3 and I'm running into this weird problem... (independent of the gem, I think I've run into this once before) I have a controller called "OauthTestController", and a model called "ConsumerToken". The model looks like this. require 'oauth/models/consumers/token' class ConsumerToken < ActiveRecord::Base include Oauth::Models::Consumers::Token end When I go to "/oauth_test/twitter", it loads the Oauth::Models::Consumers::Token module and I'm able to connect to twitter no problem. But the second time I try it (just refresh the /oauth_test/twitter url), it gives me this error: NameError (uninitialized constant Oauth): app/models/consumer_token.rb:4 app/models/twitter_token.rb:2 app/controllers/oauth_test_controller.rb:66:in `load_consumer' Why is that? It has something to do with load paths or being in development mode maybe?

  • CakePHP dynamic element

    - by Logic Artist
    I am trying to create a message-board type element in a CakePHP app. This element will be displayed on all pages and views that use a particular layout. I want it to display all the messages in the model, then show the add form when a link is clicked, then return to the updated message list when submitted. All this without affecting the current view/page. I have my message model/controller/index set up, with a message board element that requests the index action. This works fine. However I am perplexed about how to return back to the original page/action from which the link was clicked. I can't use $this-referer() because that will link back to the add() action; what I want rather is to link to the page/view before that. Any general pointers on how to achieve something like this?

  • appcfg.py upload_data entity kind problem

    - by Dingo
    Hi, I am developing application on app-engine-path and I would like to upload some data to datastore. For example I have a model models/places.py: class Place(db.Model): name = db.StringProperty() longitude = db.FloatProperty() latitude = db.FloatProperty() If I save this in view, kind() of this entity is "models_place". All is ok, Place.all() in view work fine. But: If I upload some next row using appcfg.py upload_data, the kind() of this entities is Place. loader.py look like this: import datetime, os, sys from google.appengine.ext import db from google.appengine.tools import bulkloader libs_path = os.path.join("/home/martin/myproject/src/") if libs_path not in sys.path: sys.path.insert(0, libs_path) from models import places class AlbumLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'Place', [('name', lambda x: x.decode('utf-8')), ('longitude', float), ('latitude', float), ]) loaders = [AlbumLoader] and command for uploading: python /usr/local/google_appengine/appcfg.py upload_data --config_file=places_loader.py --kind=models_place --filename=data/places.csv --url=http://localhost:8000/remote_api /home/martin/myproject/src/

  • Execution Plan Optimization when where clause is removed then added back

    - by nmushov
    I have a stored procedure that uses a table valued function which executes in 9 seconds. If I alter the table valued function and remove the where clause, the stored procedure executes in 3 seconds. If I add the where clause back, the query still executes in 3 seconds. I took a look at the execution plans and it appears that after I remove the where clause, the execution plan includes parallelism and the scan count for 2 of my tables drops for 50000 and 65000 down to 5 and 3. After I add the where clause back, the optimized execution plan still runs unless I run DBCC FREEPROCCACHE. Questions 1. Why would SQL Server start using the optimized execution plan for both queries only when I first remove the where clause? Is there a way to force SQL Server to use this execution plan? Also, this is a paramaterized all-in-one query that uses the (Parameter is null or Parameter) in the where clause, which I believe is bad for performance. RETURNS TABLE AS RETURN ( SELECT TOP (@PageNumber * @PageSize) CASE WHEN @SortOrder = 'Expensive' THEN ROW_NUMBER() OVER (ORDER BY SellingPrice DESC) WHEN @SortOrder = 'Inexpensive' THEN ROW_NUMBER() OVER (ORDER BY SellingPrice ASC) WHEN @SortOrder = 'LowMiles' THEN ROW_NUMBER() OVER (ORDER BY Mileage ASC) WHEN @SortOrder = 'HighMiles' THEN ROW_NUMBER() OVER (ORDER BY Mileage DESC) WHEN @SortOrder = 'Closest' THEN ROW_NUMBER() OVER (ORDER BY P1.Distance ASC) WHEN @SortOrder = 'Newest' THEN ROW_NUMBER() OVER (ORDER BY [Year] DESC) WHEN @SortOrder = 'Oldest' THEN ROW_NUMBER() OVER (ORDER BY [Year] ASC) ELSE ROW_NUMBER() OVER (ORDER BY InventoryID ASC) END as rn, P1.InventoryID, P1.SellingPrice, P1.Distance, P1.Mileage, Count(*) OVER () RESULT_COUNT, dimCarStatus.[year] FROM (SELECT InventoryID, SellingPrice, Zip.Distance, Mileage, ColorKey, CarStatusKey, CarKey FROM facInventory JOIN @ZipCodes Zip ON Zip.DealerKey = facInventory.DealerKey) as P1 JOIN dimColor ON dimColor.ColorKey = P1.ColorKey JOIN dimCarStatus ON dimCarStatus.CarStatusKey = P1.CarStatusKey JOIN dimCar ON dimCar.CarKey = P1.CarKey WHERE (@ExteriorColor is NULL OR dimColor.ExteriorColor like @ExteriorColor) AND (@InteriorColor is NULL OR dimColor.InteriorColor like @InteriorColor) AND (@Condition is NULL OR dimCarStatus.Condition like @Condition) AND (@Year is NULL OR dimCarStatus.[Year] like @Year) AND (@Certified is NULL OR dimCarStatus.Certified like @Certified) AND (@Make is NULL OR dimCar.Make like @Make) AND (@ModelCategory is NULL OR dimCar.ModelCategory like @ModelCategory) AND (@Model is NULL OR dimCar.Model like @Model) AND (@Trim is NULL OR dimCar.Trim like @Trim) AND (@BodyType is NULL OR dimCar.BodyType like @BodyType) AND (@VehicleTypeCode is NULL OR dimCar.VehicleTypeCode like @VehicleTypeCode) AND (@MinPrice is NULL OR P1.SellingPrice >= @MinPrice) AND (@MaxPrice is NULL OR P1.SellingPrice < @MaxPrice) AND (@Mileage is NULL OR P1.Mileage < @Mileage) ORDER BY CASE WHEN @SortOrder = 'Expensive' THEN -SellingPrice WHEN @SortOrder = 'Inexpensive' THEN SellingPrice WHEN @SortOrder = 'LowMiles' THEN Mileage WHEN @SortOrder = 'HighMiles' THEN -Mileage WHEN @SortOrder = 'Closest' THEN P1.Distance WHEN @SortOrder = 'Newest' THEN -[YEAR] WHEN @SortOrder = 'Oldest' THEN [YEAR] ELSE InventoryID END )

  • In Google App Engine, what is the simplest way to keep a record of items that you have put into memc

    - by Chris Boesch
    I am starting to use memcache more frequently to avoid having to recalculate things between page requests. When the memcache periodically clears, as it is designed to do, I have to start all over rebuilding various items that I have placed in memcache. What I would like to do is create a very simple model that enables me to periodically save the items that I put into memcache based on the memcache keys that I'm using along with a datetime that is related to the data being memcached. What is the best way to do this? I'm looking for something like this: class MemcacheRecord(db.Model): key = db.StringProperty(required=True) value = #Something that can store whatever memcache can validThru = db.DateTimeProperty(required=True) def set(self, key, value, validThru): #Save a new memcache record newMemcacheRecord = MemcacheRecord(key=key, value=value, validThru=validThru) .. return True # or False def get_latest(self, key): #Get the memcache record with the most recent validThru datetime latestMemcacheRecord = MemcacheRecord.all().order('-validThru').get() return {'validThru':latestMemcacheRecord.validThru, 'value':latestMemcachRecord.value}

  • Django: query with ManyToManyField count?

    - by AP257
    In Django, how do I construct a COUNT query for a ManyToManyField? My models are as follows, and I want to get all the people whose name starts with A and who are the lord or overlord of at least one Place, and order the results by name. class Manor(models.Model): lord = models.ManyToManyField(Person, null=True, related_name="lord") overlord = models.ManyToManyField(Person, null=True, related_name="overlord") class Person(models.Model): name = models.CharField(max_length=100) So my query should look something like this... but how do I construct the third line? people = Person.objects.filter( Q(name__istartswith='a'), Q(lord.count > 0) | Q(overlord.count > 0) # pseudocode ).order_by('name'))

  • ASP.NET MVC & ADO.NET Entity Framework clientside validation

    - by JK
    Using aspnet mvc2 with the model auto-generated by entity framework: Is it possible to tell entity framework to auto-annotate all fields? eg: If database field says not null then add [Required] If DB field is a nvarchar(x) then add [StringLength(x)] And so on? What if the field name contains the string "email" eg CustomerEmail - can I get EF to auto-annotate that with an appropriate annotation ([Regex()] maybe) As I understand it, if the model fields are annotated, and I use both Html.ValidationMessageFor() and use if (ModelState.IsValid) in my controller, then that is all I need to do to have basic clientside input validation working? Thanks

  • How are SaaS applications organized?

    - by tomekw
    Consider web (MVC, for example Rails) application for multiple clients as a service. How to design this? one application instance per client? (+ one database per client) one instance for all clients (+ one database for all clients) Former one is simple, but... "inefficient". How about the latter? (best practises, design patterns) How to separate client data? For example: worker "A" of client "1" has two documents, worker "B" of client "2" has three documents. How to build model associations to protect other users (and clients) data? I think joining every query with Client model is not a good solution.

  • Why can't I share a variable between two content sections in an ASP.NET MVC View?

    - by Dave Van den Eynde
    I have an ASP.NET MVC View with the typical TitleContent and MainContent, with a fairly complicated title that I want to calculate once and then share between these two content sections, like so: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %> <% var complicatedTitle = string.Format("{0} - {1}", Model.FirstThing, Model.SecondThing); %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> <%: complicatedTitle %> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2><%: complicatedTitle %></h2> </asp:Content> This, however, doesn't work, as the resulting error message would say that only Content controls are allowed directly in a content page that contains Content controls. The calculation definately belongs in the view. How do you solve this problem?

  • Grails pattern to reuse template on error

    - by bsreekanth
    Hello, I have a gsp template, where the data for create view is passed through the controller. def create = { def bookInstance = new Book() bookInstance .properties = params def map = getDefaultValues() render(template: "create", model: [bookInstance : bookInstance , title: map.title, somelist: somelist ....]) the gsp template <g:select optionKey="id" from="${somelist}" name="somelist.id" value="${bookInstance ?.somelist?.id}" noSelection="['null': '']"></g:select> now, in the save method, if there is an error, it returns currently populated and validated instance (default scaffold implementation) render(template: "create", model: [bookInstance : bookInstance ]) But the fields in the gsp (error page rendered from save action) is empty. I could see the reason as it looks the value in "${somelist}" , but it is not used in save method. Do i just need to check for null in the gsp and use whichever map is available, or any better method (passing all the map in the save method is not an option) .. thanks in advance..

  • Is it possible to utilize internal methods on controllers to reduce duplication?

    - by Maslow
    in a partial view I have the following: <%Html.RenderAction(MVC.User.GetComments(Model.UserGroupName)); %> can I render a Controller's PartialViewResult in a View without going through routing so I can pass arguments directly from the model so that the arguments I'm passing to the controller never get sent to the user or seen by the user? Currently the method I'm showing at the top throws an exception because no overload is public. I've got it marked as internal so that a user can not access it, only the rendering engine was my intent.

  • Hibernate mapping to object that already exists

    - by teehoo
    I have two classes, ServiceType and ServiceRequest. Every ServiceRequest must specify what kind of ServiceType it is. All ServiceType's are predefined in the database, and ServiceRequest is created at runtime by the client. Here are my .hbm files: <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="xxx.model.entity.ServiceRequest" optimistic-lock="version" polymorphism="implicit" select-before-update="false"> <id column="USER_ID" name="id"> <generator class="native"/> </id> <property name="quantity"> <column name="quantity" not-null="true"/> </property> <many-to-one cascade="all" class="xxx.model.entity.ServiceType" column="service_type" name="serviceType" not-null="false" unique="false"/> </class> </hibernate-mapping> and <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="xxx.model.entity.ServiceType" optimistic-lock="version" polymorphism="implicit" select-before-update="false"> <id column="USER_ID" name="id"> <generator class="native"/> </id> <property name="description"> <column name="description" not-null="false"/> </property> <property name="cost"> <column name="cost" not-null="true"/> </property> <property name="enabled"> <column name="enabled" not-null="true"/> </property> </class> </hibernate-mapping> When I run this, I get com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails I think my problem is that when I create a new ServiceRequest object, ServiceType is one of its properties, and therefore when I'm saving ServiceRequest to the database, Hibernate attempts to insert the ServiceType object once again, and finds that it is already exists. If this is the case, how do I make it so that Hibernate points to the exists ServiceType instead of trying to insert it again?

  • Help needed with MySQL query to join data spanning multiple tables with data used as column names

    - by gurun8
    I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

  • How to properly use CoreData validation & error framework ?

    - by Xav
    I've created a model in Xcode, and for various attributes I have minimum & maximum values defined and that are enforced by coreData at runtime. I'm using NSManagedObject validateValue:forKey:error to check for user input values. I was a bit disappointed to see that the localized error message is not specific, and I get a "The operation couldn't be completed. (Cocoa error 1620)" for too small values and a "The operation couldn't be completed. (Cocoa error 1610)" for too large values. It's written in the coreData documentation that "you can localize most aspects of a managed object model, including entity and property names and error messages". Unfortunately it's not very detailed on how you implement it for error messages. So How do you customize error message ? How do you localize them ? Is it possible to customize it in a way where it will mentioned the reference value ex: "Value should be lower than %@" or "Value should be higher than %@" ?

  • ASP.NET GridView sorting on method data

    - by husainnz
    Hi, I'm binding a GridView to a domain model object, this domain model object has a method for working out a formatted value to display on the grid. I'd like to use this method for my display value, which is fine, but I'd also like to be able to sort on the value returned by that method. My sort expression can only take in a property/field at the moment. Help please! What do I need to do to get this to work? I'm using an SPGridView actually, but that doesn't make a lot of difference to my problem. Thanks.

  • Can I use ANTLR for both two-way parsing/generating?

    - by Mike Q
    Hi all, I need to both parse incoming messages and generate outgoing messages in EDIFACT format (basically a structured delimited format). I would like to have a Java model that will be generated by parsing a message. Then I would like to use the same model to create an instance and generate a message. The first half is fine, I've used ANTLR before to go from raw - Java objects. But I've never done the reverse, or if I have it's been custom. Does ANTLR support generating using a grammar or is it really just a parse-only tool?
