When to update audit fields? DDD

- by user676767

I have a Meeting Object: Meeting{id, name, time, CreatedBy, UpdatedBy} and a MeetingAssignee{id, MeetingID, EmployeeId, CreatedBy, UpdatedBy) Meeting, as Aggregate root, has a method AssignEmployee. I was about to pass in the current user to the Meeting object as I call AssignEmployee, so that it can update its audit fields accordingly. But this doesn't seem right - is it? Obviously I can keep the audit fields public and change them later - perhaps at service level? What is everyone's else preferred method for updating these fields? Please note: We are not using Nhibernate, but a custom ORM which does not have anything automatic in place. Thanks.

Entities used to serialize data have changed. How can the serialized data be upgraded for the new entities?

- by i8abug

Hi, I have a bunch of simple entity instances that I have serialized to a file. In the future, I know that the structure of these entities (ie, maybe I will rename Name to Header or something). The thing is, I don't want to lose the data that I have saved in all these old files. What is the proper way to either load the data from the old entities into new entities upgrade the old files so that they can be used with new entities Note: I think I am stuck with binary serialization, not xml serialization. Thanks in advance! Edit: So I have an answer for the case I have described. I can use a dataContractSerializer and do something like [DataMember("bar")] private string foo; and change the name in the code and keep the same name that was used for serialization. But what about the following additional cases: The original entity has new members which can be serialized Some serialized members that were in the original entity are removed Some members have actually changed in function (suppose that the original class had a FirstName and LastName member and it has been refactored to have only a FullName member which combines the two) To handle these, I need some sort of interpreter/translator deserialization class but I have no idea what I should use

Hi i am trying to read json from a remote host by using this piece of code. <!DOCTYPE html> <html> <head> <script src="jquery.js"></script> <script> $(document).ready(function(){ $("button").click(function(){ $.getJSON("http://50.116.19.49/rest/user.json",function(result){ $.each(result, function(i, field){ $("div").append(field + " "); }); }); }); }); </script> </head> <body> <button>Get JSON data</button> <div></div> </body> </html> The problem is when i type the url in browser i get json from it.

- by Amr ElGarhy

I want to change the iframe source when something change in this iframe content, the iframe is in a different domian than the parent page. is this can be done or not? I just need to add a hash to this iframe src, so that i can access this hash value from the parent page and do some stuff based on this value. What i did: In the iframe page i wrote: window.location.hash = "close_child"; and in the parent page i wrote: if (document.getElementById("MyIFrameId").src.indexOf("#close_child") > 0) { but i always find that the src is empty

DDD and avoiding CRUD

- by g_b

It seems that on most articles I read, CRUD is to be avoided in DDD as we are dealing with modeling business process and not data. However, I find it hard to see not to have CRUD operations on certain entities. For example, in a school grading system, before teachers can grade students, a SchoolYear has to be present or perhaps a GradingPeriod. I can't see how we can manage GradingPeriods without CRUD. Could someone enlighten me on this?

Detect if the iframe content has loaded successfully.

- by skinssay

Hi, I have a widget that contains an iframe. The user can configure the url of this iframe, but if the url could not be loaded (it does not exists or the user does not have access to internet) then the iframe should failover to a default offline page. The question is, how can I detect if the iframe could be loaded or not? I tried subscribing to the 'load' event, and, if this event is not fired after some time then I failover, but this only works in Firefox, since IE and Chrome fires the 'load' event when the "Page Not Found" is displayed.

Normalized class design and code first

- by dc7a9163d9

There are the following two classes. public class Employee { int EmployeeId { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } In a DDD seminar, the speaker said the better design should be, class PersonName { public string FirstName { get; set; } public string LastName { get; set; } } class Address { public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { int EmployeeId { get; set; } public PersonName Name { get; set; } [ForeignKey("EmployerAddress")] public int EmployerAddressId { get; set; } public virtual Address EmployerAddress { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } [ForeignKey("CompanyAddress")] public int CompanyAddressId { get; set; } public virtual Address CompanyAddress { get; set; } } Is it the optimized design? How the code first generate the PersonName table and link it to Employee?

Help diagnosing Likewise Open Active Directory authentication problem

- by purpletonic

I have two servers which were up until recently authenticating against the companies Active Directory Domain controller. I believe a recent change to the Active Directory administrator password caused the servers to stop authenticating against AD. I tried to add the servers back to the domain using the command: domainjoin-cli join example.com adusername this seemed to work without complaints, but when I try to login via ssh with my domain account, I get an invalid password error. When I run the command: lw-enum-users it prints all of the domain users, and looking up my own account, I see that it is valid and my password hasn't expired. I also ran lw-get-status and received the following: LSA Server Status: Agent version: 5.0.0 Uptime: 0 days 3 hours 35 minutes 46 seconds [Authentication provider: lsa-activedirectory-provider] Status: Online Mode: Un-provisioned Domain: example.com Forest: example.com Site: Default-First-Site-Name Online check interval: 300 seconds \[Trusted Domains: 1\] \[Domain: EXAMPLE\] DNS Domain: example.com Netbios name: EXAMPLE Forest name: example.com Trustee DNS name: Client site name: Default-First-Site-Name Domain SID: S-1-5-24-1081533780-4562211299-822531512 Domain GUID: 057f0239-7715-4711-e64b-eb5eeed20e65 Trust Flags: \[0x001d\] \[0x0001 - In forest\] \[0x0004 - Tree root\] \[0x0008 - Primary\] \[0x0010 - Native\] Trust type: Up Level Trust Attributes: \[0x0000\] Trust Direction: Primary Domain Trust Mode: In my forest Trust (MFT) Domain flags: \[0x0001\] \[0x0001 - Primary\] \[Domain Controller (DC) Information\] DC Name: dc1.example.com DC Address: 10.11.0.103 DC Site: Default-First-Site-Name DC Flags: \[0x000003fd\] DC Is PDC: yes DC is time server: yes DC has writeable DS: yes DC is Global Catalog: yes DC is running KDC: yes [Authentication provider: lsa-local-provider] Status: Online Mode: Local system Anyone got any ideas what might be occurring?

Exchange 2010 - Certificate error on internal Outlook 2013 connections

- by Lorenz Meyer

I have an Exchange 2010 and Outlook 2003. The exchange server has a wildcard SSL certificate installed *.domain.com, (for use with autodiscover.domain.com and mail.domain.com). The local fqdn of the Exchange server is exch.domain.local. With this configuration there is no problem. Now I started upgrading all Outlook 2003 to Outlook 2013, and I start to get consistently a certificate error in Outlook : The Name on the security certificate is invalid or does not match the name of the site I understand why I get that error: Outlook 2013 is connecting to exch.domain.local while the certificate is for *.domain.com. I was ready to buy a SAN (Subject Alternate Names) Certificate, that contains the three domains exch.domain.local, mail.domain.com, autodiscover.domain.com. But there is a hindrance: the certificate provider (in my case Godaddy) requires that the domain is validated as being our property. Now it is not possible for an internal domain that is not accessible from the internet. So this turns out not to be an option. Create self-signed SAN certificate with an Enterprise CA is an other option that is barely viable: There would be certificate error with every access to webmail, and I had to install the certificate on all Outlook clients. What is a recommended viable solution ? Is it possible to disable certificate checking in Outlook ? Or how could I change the Exchange server configuration so that the public domain name is used for all connections ? Or is there another solution I'm not thinking of ? Any advice is welcome.

Nginx and Wordpress side-by-side with static directory alias?

- by user117161

I'm a Nginx novice, but I have it set up with Wordpress Multisite (subdirectories) and php-fpm, and it's working great as is. This lets me set up Wordpress sites off the web root: domain.com/site1 - a Wordpress network single site, which renders as expected. domain.com/site2 - ditto etc. Concurrently, I can easily create static files in the web root that don't conflict or interact with Wordpress, and they are also rendered normally. domain.com/hello.html - rendered normally domain.com/hello.php - rendered normally, including php processing domain.com/static/hello.php - rendered normally (along as "static" isn't a WP single site name) What I'd like to do, and this is where I'm out of my depth with nginx.conf, is create a root directory domain.com/static and put static sites in there domain.com/static/site3 domain.com/static/site4 and have Nginx check the request that comes into the root request comes in for: domain.com/site3 and before handing off to Wordpress, check to see if it exists in the /static folder checks: domain.com/static/site3 - static content exists there and if so, serves that content while maintaining the root URI. serves: domain.com/site3 (with content from domain.com/static/site3) if not, it lets Wordpress check if /site3 is a Wordpress single network site as it does now, and the process continues normally. In nginx.conf, in the server section, I start with this try_files rule: location / { try_files $uri $uri/ /index.php?q=$uri&$args; } I then include a bunch of Wordpress specific rules as identified at http://codex.wordpress.org/Nginx under the subdirectory section. I can see that rewrite rules might take care of it easily, but in my experimentation I've only achieved a bunch of looping (/static/static/static, etc.) and managed to bypass Wordpress if the looping stopped. Sorry if this is a very long-winded way of asking a simple question, but I'm definitely learning some of this stuff for the first time. Thanks!

AutoCompleteTextView with custom list: how to set up onClick Listeners and getting the selected item

- by steff

Hi everyone, I am working on an app which uses tags. Accessing those should be as simple as possible. Working with an AutoCompleteTextView seems appropriate to me. What I want: existing tags should be displayed in a selectable list with a CheckBox on each item's side existing tags should be displayed UPON FOCUS of AutoCompleteTextView (i.e. not after typing a letter) What I've done so far is storing tags in a dedicated sqlite3 table. Tags are queried resulting in a Cursor. The Cursor is passed to a SimpleCursorAdapter which looks like this: Cursor cursor = dbHelper.getAllTags(); startManagingCursor(cursor); String[] columns = new String[] { TagsDB._TAG}; int[] to = new int[] { R.id.tv_tags}; SimpleCursorAdapter cursAdapt = new SimpleCursorAdapter(this, R.layout.tags_row, cursor, columns, to); actv.setAdapter(cursAdapt); As you can see I created *tags_row.xml* which looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingLeft="4dip" android:paddingRight="4dip" android:orientation="horizontal"> <TextView android:id="@+id/tv_tags" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:textColor="#000" android:onClick="actv_item_click" /> <CheckBox android:id="@+id/cb_tags" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="actv_item_checked" /> </LinearLayout> It looks like this: So the results are displayed just as I'd want them to. But the TextView's onClick listener does not respond. And I don't have a clue on how to access the data once an item is (de-)selected. Behaviour of the list should be the following: tapping a CheckBox item should insert/append the corresponding tag into the AutoCompleteTextView (tags will be semicolon-seperated) tapping a TextView item should insert/apped the corresponding tag into the AutoCompleteTextView AND close the list. So please help me out. Thanks in advance, steff

How to populate a generic list of objects in C# from SQL database

- by developr

I am just learning ASP.NET c# and trying to incorporate best practices into my applications. Everything that I read says to layer my applications into DAL, BLL, UI, etc based on separation of concerns. Instead of passing datatables around, I am thinking about using custom objects so that I am loosely coupled to my data layer and can take advantage of intellisense in VS. I assume these objects would be considered DTOs? First, where do these objects reside in my layers? BLL, DAL, other? Second, when populating from SQL, should I loop through a data reader to populate the list or first fill a data table, then loop through the table to populate the list? I know you should close the database connection as soon as possible, but it seems like even more overhead to populate the data table and then loop through that for the list. Third, everything I see these days says use Linq2SQL. I am planning to learn Linq2SQL, but at this time I am working with a legacy database that doesn't have foreign keys setup and I do not have the ability to fix it atm. Also, I want to learn more about c# before I start getting into ORM solutions like nHibernate. At the same time I don't want to type out all the connection and SQL plumbing for every query. Is it ok to use the Enterprise DAAB for now?

Foreign keys in django admin list display

- by Olivier

If a django model contains a foreign key field, and if that field is shown in list mode, then it shows up as text, instead of displaying a link to the foreign object. Is it possible to automatically display all foreign keys as links instead of flat text? (of course it is possible to do that on a field by field basis, but is there a general method?) Example: class Author(models.Model): ... class Post(models.Model): author = models.ForeignKey(Author) Now I choose a ModelAdmin such that the author shows up in list mode: class PostAdmin(admin.ModelAdmin): list_display = [..., 'author',...] Now in list mode, the author field will just use the __unicode__ method of the Author class to display the author. On the top of that I would like a link pointing to the url of the corresponding author in the admin site. Is that possible? Manual method: For the sake of completeness, I add the manual method. It would be to add a method author_link in the PostAdmin class: def author_link(self, item): return '<a href="../some/path/%d">%s</a>' % (item.id, unicode(item)) author_link.allow_tags = True That will work for that particular field but that is not what I want. I want a general method to achieve the same effect. (One of the problems is how to figure out automatically the path to an object in the django admin site.)

Instantiating a list of parameterized types, making beter use of Generics and Linq

- by DanO

I'm hashing a file with one or more hash algorithms. When I tried to parametrize which hash types I want, it got a lot messier than I was hoping. I think I'm missing a chance to make better use of generics or LINQ. I also don't like that I have to use a Type[] as the parameter instead of limiting it to a more specific set of type (HashAlgorithm descendants), I'd like to specify types as the parameter and let this method do the constructing, but maybe this would look better if I had the caller new-up instances of HashAlgorithm to pass in? public List<string> ComputeMultipleHashesOnFile(string filename, Type[] hashClassTypes) { var hashClassInstances = new List<HashAlgorithm>(); var cryptoStreams = new List<CryptoStream>(); FileStream fs = File.OpenRead(filename); Stream cryptoStream = fs; foreach (var hashClassType in hashClassTypes) { object obj = Activator.CreateInstance(hashClassType); var cs = new CryptoStream(cryptoStream, (HashAlgorithm)obj, CryptoStreamMode.Read); hashClassInstances.Add((HashAlgorithm)obj); cryptoStreams.Add(cs); cryptoStream = cs; } CryptoStream cs1 = cryptoStreams.Last(); byte[] scratch = new byte[1 << 16]; int bytesRead; do { bytesRead = cs1.Read(scratch, 0, scratch.Length); } while (bytesRead > 0); foreach (var stream in cryptoStreams) { stream.Close(); } foreach (var hashClassInstance in hashClassInstances) { Console.WriteLine("{0} hash = {1}", hashClassInstance.ToString(), HexStr(hashClassInstance.Hash).ToLower()); } }

Changing values of (multiple) dropdown lists from one dropdown list in MVC

- by Mario

I have an MVC page, with some controls inside a form. The part I need help with: I have a bunch of dropdowns in a list. All dynamically named (drop{0}, where {0} is the id (really, its just a counter: 1,2,3,etc)). At the top of the list, I want to have another dropdown that will update ALL the dropdowns when it is changed. I've done similar things with checkboxes (check one and all are checked, etc) so I assume this can be done, hopefully just as simple. I'd prefer it to be on the client side, so once the form is submitted, the new values will be added/updated to the database. Edit: The values of ALL the dropdowns are static. They are all a list of 1-50, representing the number of cards I need to produce for a given record. This is how I did the checkbox: $("#chkSelectAll").click(function() { $(".checkbox").attr('checked', this.checked); }); Any thoughts on where to begin? Thanks!

Convert a (nested)HTML unordered list of links to PHP array of links

- by Klark

Hi, I have a regular, nested HTML unordered list of links, and I'd like to scrape it with PHP and convert it to an array. The original list looks something like this: <ul> <li><a href="http://someurl.com">First item</a> <ul> <li><a href="http://someotherurl.com/">Child of First Item</a></li> <li><a href="http://someotherurl.com/">Second Child of First Item</a></li> </ul> </li> <li><a href="http://bogusurl.com">Second item</a></li> <li><a href="http://bogusurl.com">Third item</a></li> <li><a href="http://bogusurl.com">Fourth item</a></li> </ul> Any of the items can have children. (The actual screen scraping is not a problem, I can do that.) I'd like to turn this into a PHP array, of just the links, while keeping the hierarchical nature of the list. Any ideas? I've looked at using htmlsimpledom and phpQuery, which both use jQuery like syntax. But, I can't seem to get the syntax right. Thanks.

This can be done at the command prompt like so: a = sorted(b, key=lambda d: (-d['Total_Points'], d['TOT_PTS_Misc'])) But I have to run this through a function, where I pass in the list and the sort keys. For example, def multikeysort(dict_list, sortkeys):. How can the lambda line be used which will sort the list, for an arbitrary number of keys that are passed in to the multikeysort function, and take into consideration that the sortkeys may have any number of keys and those that need reversed sorts will be identified with a '-' before it?

WPF Combobox Updates list but not the selected item

- by JoshReedSchramm

I have a combo box on a WPF form. On this form the user selects a record from the combo box which populates the rest of the fields on the form so the user can update that record. When they click save I am re-retrieving the combo box source which updates the combo box list. The problem is the selected item keeps the original label even though the data behind it is different. When you expand the combo box the selected item shows the right label. I am using a command binding mechanism. Here is some of the relevant code. private void SaveSalesRep() { BindFromView(); if (_salesRep.Id == 0) SalesRepRepository.AddAndSave(_salesRep); else SalesRepRepository.DataContext.SaveChanges(); int originalId = _salesRep.Id; InitSalesRepDropDown(); SalesRepSelItem = ((List<SalesRep>) SalesRepItems.SourceCollection).Find(x => x.Id == originalId); } private void InitSalesRepDropDown() { var salesRepRepository = IoC.GetRepository<ISalesRepRepository>(); IEnumerable<SalesRep> salesReps = salesRepRepository.GetAll(); _salesRepItems = new CollectionView(salesReps); NotifyPropertyChanged("SalesRepItems"); SalesRepSelItem = SalesRepItems.GetItemAt(0) as SalesRep; } The Selected Item property on the combo box is bound to SalesRepSelItem Property and the ItemsSource is bound to SalesRepItems which is backed by _salesRepItems. THe SalesRepSelItem property called NotifyPropertyChanges("SalesRepSelItem") which raises a PropertyChanged event. All told the binding of new items seems to work and the list updates, but the label on the selected item doesnt. Any ideas? Thanks all.
