  • What is the best way to provide an AutoMappingOverride for an interface in fluentnhibernate automapp

    - by Tom
    In my quest for a version-wide database filter for an application, I have written the following code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using FluentNHibernate.Automapping; using FluentNHibernate.Automapping.Alterations; using FluentNHibernate.Mapping; using MvcExtensions.Model; using NHibernate; namespace MvcExtensions.Services.Impl.FluentNHibernate { public interface IVersionAware { string Version { get; set; } } public class VersionFilter : FilterDefinition { const string FILTERNAME = "MyVersionFilter"; const string COLUMNNAME = "Version"; public VersionFilter() { this.WithName(FILTERNAME) .WithCondition("Version = :"+COLUMNNAME) .AddParameter(COLUMNNAME, NHibernateUtil.String ); } public static void EnableVersionFilter(ISession session,string version) { session.EnableFilter(FILTERNAME).SetParameter(COLUMNNAME, version); } public static void DisableVersionFilter(ISession session) { session.DisableFilter(FILTERNAME); } } public class VersionAwareOverride : IAutoMappingOverride<IVersionAware> { #region IAutoMappingOverride<IVersionAware> Members public void Override(AutoMapping<IVersionAware> mapping) { mapping.ApplyFilter<VersionFilter>(); } #endregion } } But, since overrides do not work on interfaces, I am looking for a way to implement this. Currently I'm using this (rather cumbersome) way for each class that implements the interface : public class SomeVersionedEntity : IModelId, IVersionAware { public virtual int Id { get; set; } public virtual string Version { get; set; } } public class SomeVersionedEntityOverride : IAutoMappingOverride<SomeVersionedEntity> { #region IAutoMappingOverride<SomeVersionedEntity> Members public void Override(AutoMapping<SomeVersionedEntity> mapping) { mapping.ApplyFilter<VersionFilter>(); } #endregion } I have been looking at IClassmap interfaces etc, but they do not seem to provide a way to access the ApplyFilter method, so I have not got a clue here... Since I am probably not the first one who has this problem, I am quite sure that it should be possible; I am just not quite sure how this works.. EDIT : I have gotten a bit closer to a generic solution: This is the way I tried to solve it : Using a generic class to implement alterations to classes implementing an interface : public abstract class AutomappingInterfaceAlteration<I> : IAutoMappingAlteration { public void Alter(AutoPersistenceModel model) { model.OverrideAll(map => { var recordType = map.GetType().GetGenericArguments().Single(); if (typeof(I).IsAssignableFrom(recordType)) { this.GetType().GetMethod("overrideStuff").MakeGenericMethod(recordType).Invoke(this, new object[] { model }); } }); } public void overrideStuff<T>(AutoPersistenceModel pm) where T : I { pm.Override<T>( a => Override(a)); } public abstract void Override<T>(AutoMapping<T> am) where T:I; } And a specific implementation : public class VersionAwareAlteration : AutomappingInterfaceAlteration<IVersionAware> { public override void Override<T>(AutoMapping<T> am) { am.Map(x => x.Version).Column("VersionTest"); am.ApplyFilter<VersionFilter>(); } } Unfortunately I get the following error now : [InvalidOperationException: Collection was modified; enumeration operation may not execute.] System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) +51 System.Collections.Generic.Enumerator.MoveNextRare() +7661017 System.Collections.Generic.Enumerator.MoveNext() +61 System.Linq.WhereListIterator`1.MoveNext() +156 FluentNHibernate.Utils.CollectionExtensions.Each(IEnumerable`1 enumerable, Action`1 each) +239 FluentNHibernate.Automapping.AutoMapper.ApplyOverrides(Type classType, IList`1 mappedProperties, ClassMappingBase mapping) +345 FluentNHibernate.Automapping.AutoMapper.MergeMap(Type classType, ClassMappingBase mapping, IList`1 mappedProperties) +43 FluentNHibernate.Automapping.AutoMapper.Map(Type classType, List`1 types) +566 FluentNHibernate.Automapping.AutoPersistenceModel.AddMapping(Type type) +85 FluentNHibernate.Automapping.AutoPersistenceModel.CompileMappings() +746 EDIT 2 : I managed to get a bit further; I now invoke "Override" using reflection for each class that implements the interface : public abstract class PersistenceOverride<I> { public void DoOverrides(AutoPersistenceModel model,IEnumerable<Type> Mytypes) { foreach(var t in Mytypes.Where(x=>typeof(I).IsAssignableFrom(x))) ManualOverride(t,model); } private void ManualOverride(Type recordType,AutoPersistenceModel model) { var t_amt = typeof(AutoMapping<>).MakeGenericType(recordType); var t_act = typeof(Action<>).MakeGenericType(t_amt); var m = typeof(PersistenceOverride<I>) .GetMethod("MyOverride") .MakeGenericMethod(recordType) .Invoke(this, null); model.GetType().GetMethod("Override").MakeGenericMethod(recordType).Invoke(model, new object[] { m }); } public abstract Action<AutoMapping<T>> MyOverride<T>() where T:I; } public class VersionAwareOverride : PersistenceOverride<IVersionAware> { public override Action<AutoMapping<T>> MyOverride<T>() { return am => { am.Map(x => x.Version).Column(VersionFilter.COLUMNNAME); am.ApplyFilter<VersionFilter>(); }; } } However, for one reason or another my generated hbm files do not contain any "filter" fields.... Maybe somebody could help me a bit further now ??

  • Replacement relevance sorting for MySQL fulltext in InnoDB tables?

    - by Giles Smith
    I am using MySQL InnoDB and want to do fulltext style searches on certain columns. What is the best way of sorting the results in order of relevance? I am trying to do something like: SELECT columns, (LENGTH(column_name) - LENGTH(REPLACE(column_name, '%searchterm%', ''))) AS score FROM table WHERE column_name LIKE '%searchterm%' ORDER BY score However this will become quite complicated once I start searching more than 1 column or using more than one keyword. I already have several joins happening so have simplified the query above. Can anyone suggest a better way? I don't want to use any 3rd party software like Sphinx etc

  • Dyanamic Chart Series Labels

    - by McVey
    I have some Visual Basic Code that creates a chart for each row. It sets the series values using this code: .SeriesCollection(1).Values = "=" & Ws.Name & "!R" & CurrRow & "C3:R" & CurrRow & "C8" What I am struggling with is how do I set the series labels? The series labels will always be the 1st row and be in the corresponding column. I know this is much simplier than the code above, but I am stumped. Any help is appreciated.

  • De-dupe a list of hundreds of thousands of first name/last name/address/date of birth

    - by Darren
    I have a large data set which I know contains many dupicate records. Basically I have data on first name, last name, different address components and date of birth. I think the best way to do this is to use the name and date of birth as chances are if these things match, it's the same person. There are probably lots of instances where there are slight differences in spelling (like typos missing a single letter) or use of name (ie: some might have a middle initial in first name column) which would be good to account for, but I'm not sure how to approach this. Are there any tools or articles on going about this process? The data is all in a MySQL database and I have a basic proficiency in SQL.

  • Flow diagram in html/css

    - by viraptor
    Hi, is there some good way to create a flow / swimline diagram without resorting to scripting or tables? I'm talking about showing different hosts sending packets (so hosts on the X axis, time on the Y and arrows to the destination host). It seems like too much elements for tables (especially the arrows spanning multiple columns either way), but on the other hand, divs would be hard to position in the right place horizontally (they'd have to be basically aligned to a specified "column"). Is there any good way out? Any helper frameworks? (I don't want to do canvas stuff unless really needed)

  • MySQL died during the night on a 12.04.1 Ubuntu

    - by Olivier
    I can't explain why, but somehow during the night, one of my MySQL running on an Ubuntu 12.04.1 box broke. The service is running but I can't login anymore (to SQL), the previous password is not working anymore. It does not looks like the server has been compromised (nothing in /var/auth.log) It looks like some automatic security upgrade (server is configured to perform those) has occured and broke something. The MySQL server has restarted a couple of times in the logs at the time errors started to happen (I get email when CRON task fail). In the logs it complains about an unset root password (I do have cron job running all day using SQL so the password was set & working for months). Anyway I can't login without password either! Do you have any idea of what could have happened? How do I get my databases back? This line looks strange : Nov 6 06:36:12 ns398758 mysqld_safe[6676]: ERROR: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ALTER TABLE user ADD column Show_view_priv enum('N','Y') CHARACTER SET utf8 NOT ' at line 1 Here is the full log below : Nov 6 06:36:06 ns398758 mysqld_safe[6586]: Nov 6 06:36:06 ns398758 mysqld_safe[6586]: PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

  • MPI_SCATTER Fortran Matrices by Rows

    - by Fortran
    What is the best way to scatter a Fortran 90 matrix by its rows rather than columns? That is, let's say I have a matrix a(4,50) and I want to MPI_SCATTER it onto two processes where each part is alocal(2,50), where rank 0 has rows 1 and 2, and rank 1 has 3 and 4. Now, in C, this is simple since arrays are row-major, but in Fortran 90 they are column-major. I'm trying to avoid using TRANSPOSE to flip a before scattering (i.e, doubling the memory use), and I figure there must be a way in MPI to do this. Would it be MPI_TYPE_VECTOR? MPI_TYPE_CREATE_SUBARRAY? Likewise, what if I have a 3d array b(4,50,3) and I want two scattered matrices of blocal(2,50,3) distributed as above?

  • JAVA: Sort ArrayList<ArrayList<Integer>> on multiple columns

    - by Bob
    First, I did do my homework searching before posting here. My requirement seems to be slightly different compared to questions posted out there. I have a matrix like ArrayList<ArrayList<Integer>> in the following form | id1 | id2 | score | |-----|-----|-------| | 1 | 3 | 95% | | 1 | 2 | 100% | | 1 | 4 | 85% | | 1 | 5 | 95% | | 2 | 10 | 80% | | 2 | 15 | 99% | I want to sort the matrix column-wise (first using score, then the id1). I already have the id1 in a sorted manner. That means I also need to sort all records with the same id1 first by using score, second by the id2. The reason for doing this is to create a ranking of the id2 in each id1. The result for the above example would be: | q_id | d_id | rank | score | |------|------|------|-------| | 1 | 2 | 1 | 100% | | 1 | 3 | 2 | 95% | | 1 | 5 | 3 | 95% | | 1 | 4 | 4 | 85% | | 2 | 15 | 1 | 99% | | 2 | 10 | 2 | 80% | How can I achieve this in Java using some built-in methods of collections?

  • SQLite3's dynamic typing

    - by Bradford Larsen
    SQLite3 uses dynamic typing rather than static typing, in contrast to other flavors of SQL. The SQLite website reads: Most SQL database engines (every SQL database engine other than SQLite, as far as we know) uses static, rigid typing. With static typing, the datatype of a value is determined by its container - the particular column in which the value is stored. SQLite uses a more general dynamic type system. In SQLite, the datatype of a value is associated with the value itself, not with its container. It seems to me that this is exactly what you don't want, as it lets you store, for example, strings in integer columns. The page continues: ...the dynamic typing in SQLite allows it to do things which are not possible in traditional rigidly typed databases. I have two questions: The use case question: What are some examples where sqlite3's dynamic typing is, in fact, beneficial? The historical/design question: What was the motivation for implementing sqlite with dynamic typing?

    Hi, I has a Django view which is accessed through an AJAX call. It's a pretty simple one — all it does is simply pass the request to a form object and save the data. Here's a snippet from my view: form = AddSiteForm(request.user, request.POST) if form.is_valid(): obj = form.save(commit=False) obj.user = request.user obj.save() data['status'] = 'success' data['html'] = render_to_string('site.html', locals(), context_instance=RequestContext(request)) return HttpResponse(simplejson.dumps(data), mimetype='application/json') How do I get the currently saved object (including the internally generated id column) and pass it to the template? Any help guys? Mridang

  • multicolumn sorting of WinForms DataGridView

    - by Bi
    I have a DataGridView in a windows form with 3 columns: Serial number, Name, and Date-Time. The Name column will always have either of the two values: "name1" or "name2". I need to sort these columns such that the grid displays all the rows with name values in a specific order (first display all the "name1" rows and then all the "name2" rows). Within the "name1" rows, I want the rows to be sorted by the Date-Time. Please note programmatically, all the 3 columns are strings. For example, if I have the rows: 01 |Name1 | 2010-05-05 10:00 PM 02 |Name2 | 2010-05-02 08:00 AM 03 |Name2 | 2010-05-01 08:00 AM 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM needs to be sorted as 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM 01 |Name1 | 2010-05-05 10:00 PM 03 |Name2 | 2010-05-01 08:00 AM 02 |Name2 | 2010-05-02 08:00 AM I am not sure how to go about using the below: myGrid.Sort(.....,ListSortDirection.Ascending)

  • Synchronize model in MySQL Workbench

    - by Álvaro G. Vicario
    After reading the documentation for MySQL Workbench I got the impression that it's possible to alter a database in the server (e.g. add a new column) and later incorporate the DDL changes into your EER diagram. At least, it has a Synchronize Model option in the Database menu. I found it a nice feature because I could use a graphic modelling tool without becoming its prisoner. In practice, when I run such tool I'm offered these options: Model Update Source ================ ====== ====== my_database_name --> ! N/A my_table_name --> ! N/A N/A --> ! my_database_name N/A --> ! my_table_name I can't really understand it, but leaving it as is I basically get: DROP SCHEMA my_database_name CREATE SCHEMA my_database_name CREATE TABLE my_table_name This is dump of the model that overwrites all remote changes in my_table_name. Am I misunderstanding the feature?

  • .xcodeproj does not get committed with XCode's SCM Tool

    - by Dimitris
    I am using the SCM Tools embedded in XCode to manage my app's versioning. I have created an iPhone app and I have added/committed it to the Subversion server but the .xcodeproj file won't upload (all the class files, resources etc are there)! I don't even get the option to "Add to Repository". Sometimes it gets an "A" (add) next to it under the "SCM" column but still, the next time I commit changes or commit entire project it still doesn't upload and show up on the server. As a result my team can't get and run the project. Is there a way to so something (other than just use the terminal or Versions)? Thank you.

  • Populate a combo box with one data tabel and save the choice in another.

    - by Scott Chamberlain
    I have two data tables in a data set for example lets say Servers: | Server | Ip | Users: | Username | Password | Server | and there is a foreign key on users that points to servers. How do I make a combo box that list all of the servers. Then how do I make the selected server in that combo box be saved in the data set in the Server column of the users table. EDIT -- I havent tested it yet but is this the right way? this.bsServers.DataMember = "Servers"; this.bsServers.DataSource = this.dataSet; this.bsUsers.DataMember = "FK_Users_Servers"; this.bsUsers.DataSource = this.bsServers; this.serverComboBox.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", this.bsUsers, "Server", true)); this.serverComboBox.DataSource = this.bsServers; this.serverComboBox.DisplayMember = "Server"; this.serverComboBox.ValueMember = "Server";

  • What is the android_metadata table?

    - by Janusz
    I try to integrate an existing database file into my Android project. I follow the instructions on this blog. They write that I have to add a table android_metadata with a column called locale and put en_US into it. I try to figure out what this table is used for. Because my database content is german. Maybe i then should not put en_US into it? Is this required for localisation of the database content or is the table not needed at all?

  • Large XML files in dataset (outofmemory)

    - by dklein
    Hi folks, I am currently trying to load a slightly large xml file into a dataset. The xml file is about 700 MB and every time I try to read the xml it needs plenty of time and after a while it throws an "out of memory" exception. DataSet ds = new DataSet(); ds.ReadXml(pathtofile); The main problem is, that it is necessary for me to use those datasets (I use it to import the data from xml file into a sybase database (foreach table, foreach row, foreach column)) and that I have no scheme file. I already googled a while, but I did only find solutions that won't be usable for me.

  • Linked servers SQLNCLI problem. "No transaction is active"

    - by Felipe Fiali
    Im trying to execute a stored procedure and simply insert its results in a temporary table, and I'm getting the following message: The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "MyServerName" was unable to begin a distributed transaction. OLE DB provider "SQLNCLI" for linked server "MyServerName" returned message "No transaction is active.". My query looks like this: INSERT INTO #TABLE EXEC MyServerName.MyDatabase.dbo.MyStoredProcedure Param1, Param2, Param3 Exact column number, names, the problem is not the result. MSDTC is allowed and started in both computers, Remote procedure calling too. The machines are not in the same domain, but I can execute remote queries from my machine and get the result. I can even execute the stored procedure and see its results, I just can't insert it in another table. Help, please? :)

  • Error when trying to create a faceted plot in ggplot2

    I am trying to make a faceted plot in ggplot2 of the coefficients on the regressors from two linear models with the same predictors.

  • jQuery datepicker onSelect set multiple row values

    - by d3020
    On the select event of the datepicker I need to add and set values in multiple rows. In other words, I have something like this... Days Value Row 1 1 Row 2 2 Row 3 3 I have the "Days" and "Value" columns as textboxes. When I select a date from the datepicker I need to add the "Days" value for each row to the date selected. That value is what goes into the "Value" column. Example, I select 4/20/2010. The value in each respective row would then be 4/21/2010, 4/22/2010, 4/23/2010. Hopefully this makes sense and thank you for the help in advance.

  • CSS - 100% Height Layout with Variable Height Header

    - by Brian D.
    The layout I want to achieve is pretty simple. I want a 100% height layout with a header, and below the header I will have a side bar for navigation and then the content area beside the navigation bar (2-column with header). I can easily do this if I give the header a specified height but I want the header to just take up as much room as is needed. Does anyone know how to do this? Is it possible without knowing the height of the header? Thanks for any help.
