  • Automatic database schema generation and migration with Perl

    - by pistacchio
    In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any Perl module that does the same? Eg, it takes the YAML/XML/JSON description of a database as input and modifies/generates the database schema accordingly?

  • Apache tiles and body onload event. Known issue?

    - by Angus
    We're prototyping a new visual framework using Apache Tiles for markup templating. Often the document onload event (actually prototype's dom:loaded event) is getting fired before all DOM objects are actually loaded Is it possible that the tiles templates are loading in an asynchronous fashion and therefore doing an end run around the event handler? Has anyone else had this experience? Can anyone share a robust workaround? thanks in advance

    I want a dictionary containing the names and text of all controls. Is it possible with predefined framework methods/LINQ/colection initializers or do I have to make a loop and add all entries by myself? This gives me an error message: List<Control> controls; // .. initialize list .. controls.ToDictionary((Control child,string k)=>new KeyValuePair<string,string>(child.Name, child.Text));

    - by Angela
    Hi, just set up FirePHP and using a framework called Qcodo / Qcubed. Has anyone heard of these on SO? Been having challenges debugging -- trying to do a fairly simple new() and save() and then output via Ajax but not getting any kind of responsiveness from errors. Any help for us, two of us have checked it out but can't seem to get a response. Thanks! BTW, here's the class which seems to be creating the problems: http://github.com/allyforce/AF-upload/blob/master/Library/Target1.class.php

  • NHibernate IUserType convert nullable DateTime to DB not-null value

    - by barakbbn
    I have legacy DB that store dates that means no-date as 9999-21-31, The column Till_Date is of type DateTime not-null="true". in the application i want to build persisted class that represent no-date as null, So i used nullable DateTime in C# //public DateTime? TillDate {get; set; } I created IUserType that knows to convert the entity null value to DB 9999-12-31 but it seems that NHibernate doesn't call SafeNullGet, SafeNullSet on my IUserType when the entity value is null, and report a null is used for not-null column. I tried to by-pass it by mapping the column as not-null="false" (changed only the mapping file, not the DB) but it still didn't help, only now it tries to insert the null value to the DB and get ADOException. Any knowledge if NHibernate doesn't support IUseType that convert null to not-null values? Thanks //Implementation public class NullableDateTimeToNotNullUserType : IUserType { private static readonly DateTime MaxDate = new DateTime(9999, 12, 31); public new bool Equals(object x, object y) { //This didn't work as well if (ReferenceEquals(x, y)) return true; //if(x == null && y == null) return false; if (x == null || y == null) return false; return x.Equals(y); } public int GetHashCode(object x) { return x == null ? 0 : x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { var value = rs.GetDateTime(rs.GetOrdinal(names[0])); return (value == MaxDate)? null : value; } public void NullSafeSet(IDbCommand cmd, object value, int index) { var dateValue = (DateTime?)value; var dbValue = (dateValue.HasValue) ? dateValue.Value : MaxDate; ((IDataParameter)cmd.Parameters[index]).Value = dbValue; } public object DeepCopy(object value) { return value; } public object Replace(object original, object target, object owner) { return original; } public object Assemble(object cached, object owner) { return cached; } public object Disassemble(object value) { return value; } public SqlType[] SqlTypes { get { return new[] { NHibernateUtil.DateTime.SqlType }; } } public Type ReturnedType { get { return typeof(DateTime?); } } public bool IsMutable { get { return false; } } } } //Final Implementation with fixes. make the column mapping in hbm.xml not-null="false" public class NullableDateTimeToNotNullUserType : IUserType { private static readonly DateTime MaxDate = new DateTime(9999, 12, 31); public new bool Equals(object x, object y) { //This didn't work as well if (ReferenceEquals(x, y)) return true; //if(x == null && y == null) return false; if (x == null || y == null) return false; return x.Equals(y); } public int GetHashCode(object x) { return x == null ? 0 : x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { var value = NHibernateUtil.Date.NullSafeGet(rs, names[0]); return (value == MaxDate)? default(DateTime?) : value; } public void NullSafeSet(IDbCommand cmd, object value, int index) { var dateValue = (DateTime?)value; var dbValue = (dateValue.HasValue) ? dateValue.Value : MaxDate; NHibernateUtil.Date.NullSafeSet(cmd, valueToSet, index); } public object DeepCopy(object value) { return value; } public object Replace(object original, object target, object owner) { return original; } public object Assemble(object cached, object owner) { return cached; } public object Disassemble(object value) { return value; } public SqlType[] SqlTypes { get { return new[] { NHibernateUtil.DateTime.SqlType }; } } public Type ReturnedType { get { return typeof(DateTime?); } } public bool IsMutable { get { return false; } } } }

  • How to create a CMS web site using OFBiz

    I need a simple how-to tutorial on developing a simple CMS web site using the OFBiz CMS framework. There are absolutely no documentation of how OFBiz CMS works. Whatever is there in the official website is only about the data model used in OFBiz CMS application. If somebody can illustrate just a "Hello World" like application in OFBiz CMS, it will great help for me. Or can guide me to similar documents in web.

  • How to select and AMI when creating an instance of EC2

    I am using Amazon EC2 for the first time, and need to create an instance that runs Windows, MSSQL Server 2008, .Net Framework 3.5 SP1 and IIS Server 6.0. I am unable to decide what AMI (out of the huge list of community AMIs) should I choose to meet my requirements. Is there a way I can make this decision without doing trial and error.

  • Do you always use the same technologies/frameworks?

    - by James.Elsey
    When given a new task/challenge/application to build, do you always use the same framework, for example spring / struts? Or do you try something new that you haven't used before, such as GWT? What makes you return to the same technology stack? Is it good to be advanced at particular technologies, or to have a broad understanding?

  • Validating method arguments with Data Annotation attributes

    - by schemer
    The "Silverlight Business Application" template bundled with VS2010 / Silverlight 4 uses DataAnnotations on method arguments in its domain service class, which are invoked automagically: public CreateUserStatus CreateUser(RegistrationData user, [Required(ErrorMessageResourceName = "ValidationErrorRequiredField", ErrorMessageResourceType = typeof(ValidationErrorResources))] [RegularExpression("^.*[^a-zA-Z0-9].*$", ErrorMessageResourceName = "ValidationErrorBadPasswordStrength", ErrorMessageResourceType = typeof(ValidationErrorResources))] [StringLength(50, MinimumLength = 7, ErrorMessageResourceName = "ValidationErrorBadPasswordLength", ErrorMessageResourceType = typeof(ValidationErrorResources))] string password) { /* do something */ } If I need to implement this in my POCO class methods, how do I get the framework to invoke the validations OR how do I invoke the validation on all the arguments imperatively (using Validator or otherwise?).

  • Binding to a collection of DependencyObjects in Silverlight 4

    - by Meik
    As of Silverlight 4 it is possible to data bind against a DependencyObject (instead of a Framework element in previous versions). So far so good, but how do I bind agains a collection of DependencyObjects. The DataContext is not passed from the ObservableCollection to the collection elements, so that the DependencyProperties of the DependencyObjects are never called (neither the changed events). Neither the DependencyObject offers SetBinding or DataContext to initialize the binding manually. Thanks for any advice here.
