  • Unidirectional OneToMany in Doctrine 2

    - by darja
    I have two Doctrine entities looking like that: /** * @Entity * @Table(name = "Locales") */ class Locale { /** * @Id @Column(type="integer") * @GeneratedValue(strategy="IDENTITY") */ private $id; /** @Column(length=2, name="Name", type="string") */ private $code; } /** * @Entity * @Table(name = "localized") */ class LocalizedStrings { /** * @Id @Column(type="integer") * @GeneratedValue(strategy="IDENTITY") */ private $id; /** @Column(name="Locale", type="integer") */ private $locale; /** @Column(name="SomeText", type="string", length=300) */ private $someText; } I'd like to create reference between these entities. LocalizedStrings needs reference to Locale but Locale doesn't need reference to LocalizedStrings. How to write such mapping via Doctrine 2?

  • Getting data from function loaded after current function

    - by Hwang
    I have 2 functions, 1 loaded before another. Some value are determine by the other function data, but since one of it has to load before the other 1, how should I get the data that is loaded after current function? private function wMessage():void { Message.width=Name.width+20; } private function wName():void { Name.x=(Message.x+Message.textWidth)-Name.textWidth; Name.y=Message.y+Message.height; } I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name

  • Stuck on an ASP.NET/WCF WSDL Parsing Error

    - by Vaccano
    I have a WCF Web Service that my ASP.NET app uses. It has been working fine for quite some time. I just added in a Dev Express Grid (and the Dev Express DLLs) and a new page that uses them and now I am getting parsing errors on the WSDL. But the weird part is that it works fine on my machine but fails on the web server machine. (Both are connecting to the same web services WSDL.) Here is the error message I am getting: Server Error in '/MyWebAppWebDev' Application. -------------------------------------------------------------------------------- Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

  • Error messages for model validation using data annotations

    - by oneBelizean
    Given the follow classes: using System.ComponentModel.DataAnnotations; public class Book{ public Contact PrimaryContact{get; set;} public Contact SecondaryContact{get; set;} [Required(ErrorMessage="Book name is required")] public string Name{get; set;} } public class Contact{ [Required(ErrorMessage="Name is required")] public string Name{get; set;} } Is there a clean way I can give a distinct error message for each instance of Contact in Book using DataAnnotations? For example, if the name was missing from the PrimaryContact instance the error would read "primary contact name is required". My current solution is to create a validation service that checks the model state for field errors then remove said errors and add them back using the specific language I'd like.

  • SQLAlchemy automatically converts str to unicode on commit

    - by Victor Stanciu
    Hello, When inserting an object into a database with SQLAlchemy, all it's properties that correspond to String() columns are automatically transformed from <type 'str'> to <type 'unicode'>. Is there a way to prevent this behavior? Here is the code: from sqlalchemy import create_engine, Table, Column, Integer, String, MetaData from sqlalchemy.orm import mapper, sessionmaker engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() table = Table('projects', metadata, Column('id', Integer, primary_key=True), Column('name', String(50)) ) class Project(object): def __init__(self, name): self.name = name mapper(Project, table) metadata.create_all(engine) session = sessionmaker(bind=engine)() project = Project("Lorem ipsum") print(type(project.name)) session.add(project) session.commit() print(type(project.name)) And here is the output: <type 'str'> <type 'unicode'> I know I should probably just work with unicode, but this would involve digging through some third-party code and I don't have the Python skills for that yet :)

  • How do you get XML::Pastor to set xsi:type for programmatically generated elements?

    - by Derrick
    I'm learning how to use Perl as an automation test framework tool for a Java web service and running into trouble generating xml requests from the Pastor generated modules. The problem is that when including a type that extends from the required type for an element, the xsi:type is not included in the generated xml string. Say, for example, I want to generate the following xml request from the modules that XML::Pastor generated from my xsd: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer xsi:type="textPromptAnswer" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <Prompt ref="2"/> <Children> <PromptAnswer xsi:type="choicePromptAnswer"> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> What I'm getting currently is this: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <PromptAnswersRequest xmlns="http://mycompany.com/api"> <Uri>/some/url</Uri> <User ref="1"/> <PromptAnswers> <PromptAnswer> <Prompt ref="2"/> <Children> <PromptAnswer> <Prompt ref="1"/> <Choice ref="2"/> </PromptAnswer> </Children> <Value>totally</Value> </PromptAnswer> </PromptAnswers> </PromptAnswersRequest> Here are some relavent snippets from the xsd: <xs:complexType name="request"> <xs:sequence> <xs:element name="Uri" type="xs:anyURI"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswersRequest"> <xs:complexContent> <xs:extension base="api:request"> <xs:sequence> <xs:element name="User" type="api:ref"/> <xs:element name="PromptAnswers" type="api:promptAnswerList"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="promptAnswerList"> <xs:sequence> <xs:element name="PromptAnswer" type="api:promptAnswer" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="promptAnswer" abstract="true"> <xs:sequence> <xs:element name="Prompt" type="api:ref"/> <xs:element name="Children" type="api:promptAnswerList" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="textPromptAnswer"> <xs:complexContent> <xs:extension base="promptAnswer"> <xs:sequence> <xs:element name="Value" type="api:nonEmptyString" minOccurs="0"/> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> And here are relavent parts of the script: my $promptAnswerList = new My::API::Type::promptAnswerList; my @promptAnswers; my $promptAnswerList2 = new My::API::Type::promptAnswerList; my @textPromptAnswerChildren; my $textPromptAnswer = new My::API::Type::textPromptAnswer; my $textPromptAnswerRef = new My::API::Type::ref; $textPromptAnswerRef->ref('2'); $textPromptAnswer->Prompt($textPromptAnswerRef); my $choicePromptAnswer = new My::API::Type::choicePromptAnswer; my $choicePromptAnswerPromptRef = new My::API::Type::ref; my $choicePromptAnswerChoiceRef = new My::API::Type::ref; $choicePromptAnswerPromptRef->ref('1'); $choicePromptAnswerChoiceRef->ref('2'); $choicePromptAnswer->Prompt($choicePromptAnswerPromptRef); $choicePromptAnswer->Choice($choicePromptAnswerChoiceRef); push(@textPromptAnswerChildren, $choicePromptAnswer); $promptAnswerList2->PromptAnswer(@textPromptAnswerChildren); $textPromptAnswer->Children($promptAnswerList2); $textPromptAnswer->Value('totally'); push(@promptAnswers, $pulseTextPromptAnswer); push(@promptAnswers, $textPromptAnswer); I haven't seen this addressed anywhere in the documentation for the XML::Pastor modules, so if anyone can point me at a good reference for its use it would be greatly appreciated. Also, I'm only using XML::Pastor because I don't know of any other modules that can do this, so if any of you know of something either easier to use, or more well maintained, please let me know about that too!

  • MongoDB - how to join parent and child products by reference

    - by Jaro
    my mongo collection stores products. There are two product types: child and parent. Parent product holds array of its child as reference. Use case: use mydb; child1 = { _id: 1, name: "Child 1", is_child: true, is_parent: false, children : [] } child2 = { _id: 2, name: "Child 2", is_child: true, is_parent: false, children : [] } parent = { _id: 3, name: "Parent product", is_child: false, is_parent: true, children : [1, 2] } db.product.insert( [child1, child2, parent] ); And I'm looking for any query returning { _id: 3, name: "Parent product", is_child: false, is_parent: true, children: [ { _id: 1, name: "Child 1", is_child: true, is_parent: false, children : [] }, { _id: 2, name: "Child 2", is_child: true, is_parent: false, children : [] } ] } I'm newbie to mongodb, but I guess an usage of map-reduce could solve the problem. Can anyone advice? Thx

  • How can I instantiate a base class and then convert it to a derived class?

    - by Eric
    I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

  • How to have combobox take data from a child datasource

    - by SkollSunman
    I am trying to have a datagridview with two comboboxes, a company name and a supplier account number. When a company name is selected the relevant supplier account numbers (a company can have more than one supplier account) should be filtered for that company in that row. I have a datagridview with two bindingsources: supplierBindingSource and companyBindingSource and the Supplier account combobox uses the supplierBindingSource for its datasource and company name uses the companyBindingSource for its datasource. A company can have a supplier and/or customer account so the supplierBindingSource is a child or a companyBindingSource. The supplier accounts correctly filter based on the selected company name however when another company name is selected in another row all the supplier accounts are filtered for that company. Saving still works properly, regardless of what the combo box show but currently it is very confusing for a user to select a supplier account when the labels don't show what is being saved. Is it possible to have only the selected row to filter based on the company name rather than every row? EDIT: Thanks to the answer from http://social.msdn.microsoft.com/Forums/windows/en-US/b23d9e8f-a00a-49ba-adf5-52d87c1b2890/parent-child-comboboxes-in-datagridview I have been able to make some progress. The supplier account gets filtered when the drop down box is selected and restored to the full list when selection is finished. However now I am trying to have the company selected (and not filtered) when a supplier account is selected. The issue I've run into now is that I can get the companyID (which is the valuemember for the company combobox) but I cannot select the appropriate company without just setting the value of the combobox to the companyID which displays the companyID instead of the company name. Is there a way to select the company using the companyID while preserving the displaymember/valuemember dynamic? EDIT 2: The wall of text may be off putting. Some code to help elucidate my issue DataGridViewComboBoxCell dgcb2 = (DataGridViewComboBoxCell)sdgvSalesOrderLines[cmbSupplierName.Index, e.RowIndex]; var companyID = col.FirstOrDefault(c => c.AccountID == Convert.ToInt32(dgcb.Value)).CompanyID; dgcb2.Value = companyID.toString(); The second line gets the companyID and that works just fine, the final line sets the combobox to display the companyID whereas I would like it to set the valuemember value to companyID so that it would display the corresponding company name. I can set the second line to give me the company name instead but if the value of the combobox isn't the companyID then the supplier account cannot filter based on the company selected.

  • C# Select clause returns system exception instead of relevant object

    - by Kashif
    I am trying to use the select clause to pick out an object which matches a specified name field from a database query as follows: objectQuery = from obj in objectList where obj.Equals(objectName) select obj; In the results view of my query, I get: base {System.SystemException} = {"Boolean Equals(System.Object)"} Where I should be expecting something like a Car, Make, or Model Would someone please explain what I am doing wrong here? The method in question can be seen here: // this function searches the database's table for a single object that matches the 'Name' property with 'objectName' public static T Read<T>(string objectName) where T : IEquatable<T> { using (ISession session = NHibernateHelper.OpenSession()) { IQueryable<T> objectList = session.Query<T>(); // pull (query) all the objects from the table in the database int count = objectList.Count(); // return the number of objects in the table // alternative: int count = makeList.Count<T>(); IQueryable<T> objectQuery = null; // create a reference for our queryable list of objects T foundObject = default(T); // create an object reference for our found object if (count > 0) { // give me all objects that have a name that matches 'objectName' and store them in 'objectQuery' objectQuery = from obj in objectList where obj.Equals(objectName) select obj; // make sure that 'objectQuery' has only one object in it try { foundObject = (T)objectQuery.Single(); } catch { return default(T); } // output some information to the console (output screen) Console.WriteLine("Read Make: " + foundObject.ToString()); } // pass the reference of the found object on to whoever asked for it return foundObject; } } Note that I am using the interface "IQuatable<T>" in my method descriptor. An example of the classes I am trying to pull from the database is: public class Make: IEquatable<Make> { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<Model> Models { get; set; } public Make() { // this public no-argument constructor is required for NHibernate } public Make(string makeName) { this.Name = makeName; } public override string ToString() { return Name; } // Implementation of IEquatable<T> interface public virtual bool Equals(Make make) { if (this.Id == make.Id) { return true; } else { return false; } } // Implementation of IEquatable<T> interface public virtual bool Equals(String name) { if (this.Name.Equals(name)) { return true; } else { return false; } } } And the interface is described simply as: public interface IEquatable<T> { bool Equals(T obj); }

  • jQuery AJAX Web service works only locally

    - by Greg
    Hi, I have a simple ASP.NET Web Service [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.Web.Script.Services.ScriptService] public class Service : System.Web.Services.WebService { public Service () { } [WebMethod] public string SetName(string name) { return "hello my dear friend " + name; } } For this Web Service I created Virtual Directory, so I can receive the access by taping http://localhost:89/Service.asmx. I try to call it via simple html page with jQuery. For this purpose I use function CallWS() { $.ajax({ type: "POST", data: "{'name':'Pumba'}", dataType: "json", url: "http://localhost:89/Service.asmx/SetName", contentType: "application/json; charset=utf-8", success: function (msg) { $('#DIVid').html(msg.d); }, error: function (e) { $('#DIVid').html("Error"); } }); The most interesting fact: If I create the html page in the project with my WebService and change url to Service.asmx/SetName everything works excellent. But if I try to call this webservice remotely - success function works but msg is null. After that I tried to call this service even via SOAP. It is the the same - locally it works excellent, but remotely - not at all. var ServiceUrl = 'http://localhost:89/Service.asmx?op=SetName'; function beginSetName(Name) { var soapMessage = '<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <SetName xmlns="http://tempuri.org/"> <name>' + Name + '</name> </SetName> </soap:Body> </soap:Envelope>'; $.ajax({ url: ServiceUrl, type: "POST", dataType: "xml", data: soapMessage, complete: endSetName, contentType: "text/xml; charset=\"utf-8\"" }); return false; } function endSetName(xmlHttpRequest, status) { $(xmlHttpRequest.responseXML) .find('SetNameResult') .each(function () { var name = $(this).text(); alert(name); }); } In this case status has value "parseerror". Could you please help me to resolve this problem? What should I do to call another WebService remotely by url via jQuery. Thank you in advance, Greg

  • Differences between query using LINQ and IQueryable interface directly?

    - by JohnMetta
    Using Entity Framework 4, and given: ObjectSet<Thing> AllThings = Context.CreateObjectSet<Thing>; public IQueryable<Thing> ByNameA(String name) { IQueryable<Thing> query = from o in AllThings where o.Name == name select o; return query; } public IQueryable<Thing> ByNameB(String name) { return AllThings.Where((o) => o.Name == name); } Both return IQueryable< instances, and thus the query doesn't hit the server until something like ToList() is called, right? Is it purely readability that is the difference, or are the using fundamentally different technologies on the back-end?

  • How to direct people to fill out a form

    - by Solmead
    What is the best way to get people to fill out a form correctly? For instance I originally had a "Name" field on a form and I want 1 person per form. People filled it out like this: "Mark & Becky Newsman". So I broke it into 2 fields, "First Name" and "Last Name", And people are still filling it out wrong, like "First Name" = "Mark & Becky", "Last Name" = "Newsman". Are there any recommendations on how better to get people to understand that only one person's name should go there? I currently have it on two lines, would it work better to put both fields on one line? If this is on the wrong site go ahead and move it to the correct site.

  • jQuery.extend() not giving deep copy of object formed by constructor

    - by two7s_clash
    I'm trying to use this to clone a complicated Object. The object in question has a property that is an array of other Objects, and each of these have properties of different types, mostly primitives, but a couple further Objects and Arrays. For example, an ellipsed version of what I am trying to clone: var asset = new Assets(); function Assets() { this.values = []; this.sectionObj = Section; this.names = getNames; this.titles = getTitles; this.properties = getProperties; ... this.add = addAsset; function AssetObj(assetValues) { this.name = ""; this.title = ""; this.interface = ""; ... this.protected = false; this.standaloneProtected = true; ... this.chaptersFree = []; this.chaptersUnavailable = []; ... this.mediaOptions = { videoWidth: "", videoHeight: "", downloadMedia: true, downloadMediaExt: "zip" ... } this.chaptersAvailable = []; if (typeof assetValues == "undefined") { return; } for (var name in assetValues) { if (typeof assetValues[name] == "undefined") { this[name] = ""; } else { this[name] = assetValues[name]; } } ... function Asset() { return new AssetObj(); } ... function getProperties() { var propertiesArray = new Array(); for (var property in this.values[0]) { propertiesArray.push(property); } return propertiesArray; } ... function addAsset(assetValues) { var newValues; newValues = new AssetObj(assetValues); this.values.push(newValues); } } When I do var copiedAssets = $.extend(true, {}, assets); copiedAssets.values == [], while assets.values == [Object { name="section_intro", more...}, Object { name="select_textbook", more...}, Object { name="quiz", more...}, 11 more...] When I do var copiedAssets = $.extend( {}, assets); all copiedAssets.values.[X].properties are just pointers to the value in assets. What I want is a true deep copy all the way down. What am I missing? Do I need to write a custom extend function? If so, any recommended patterns?
