• Hibernate Many-To-One Foreign Key Default 0

  - by user573648

  I have a table where the the parent object has an optional many-to-one relationship. The problem is that the table is setup to default the fkey column to 0. When selecting, using fetch="join", etc-- the default of 0 on the fkey is being used to try over and over to select from another table for the ID 0. Of course this doesn't exist, but how can I tell Hibernate to treat a value of 0 to be the same as NULL-- to not cycle through 20+ times in fetching a relationship which doesn't exist? <many-to-one name="device" lazy="false" class="Device" not-null="true" access="field" cascade="none" not-found="ignore"> <column name="DEVICEID" default="0" not-null="false"/>

• Searching in Rails 3

  - by cbarton

  Here is the situation: I have the need to search for specifics or generals, much like expedia.com or your local library catalog search. In that there are fields that may or may not be filled out based on the individual need. It acts much like an "advanced search page". I have all of that code done for the models/controller and such and have it setup with a Searches controller along with matching model and views. The question that I have is there a way to cut down the amount of parameters posted to GET so that the url isn't search?search[:a]=""+search[:b]=""+search[:c]="x"... plus the unicode checkmark. I only want the filled out fields to be shown in the response link especially minus the checkmark. cbarton

• Entity Framework Create Database & Tables At Runtime

  - by dhsto

  I created some tables in an .edmx file and have been generating the database by selecting "Generate Database From Model" and manually executing an .edmx.sql file on the database to build the tables. Now, however, I am creating a setup dialog that allows the user to connect the program up to their own database. I thought running context.CreateDatabase would be good enough to create the database, along with the tables, but the tables are not created. What is the preferred method for creating the database and tables when the user specifies their own server and database to use, when originally starting with a model?

• Confusion using MYSQLI

  - by user1020069

  I just started using mysqli API for PHP. Apparently, every time an object of the class MYSQLI is instantiated, it can setup a connection to the database as it connects to the server unlike mysql_connect, which connects to the server first and then you are required to specify the database to query. Now this is a good problem if the db exists, in my case, the db does not exist on the first ever connection to the server/execution of the problem, hence I must connect without specifying the database, which is fine, since the msyqli constructor does not make this database mandatory. My challenge is essentially, how do I check if the database exists before attempting the first connection. The only way to really do this would be to establish a conection to the server and then use the result of the following query to gauge if the database exists: SELECT COUNT(*) AS `exists` FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMATA.SCHEMA_NAME="dbname" ; If this returns true, then the database exists, but now the challenge is how do I get the mysqli object to query this database rather than having to prefix the name of the database in the query. Thanks much

• Core Data strategy using in memory cache, or no core data at all?

  - by randombits

  I have a user interface where the user can check off a bunch of items from a tableview, almost like a todo list. The items are populated from a Core Data stack. I need to be able to take all of the items they're clicking through and put them into a "temporary" shopping cart. Once they're in the shopping cart, users can go through the list and remove the items, or just submit them to a server. The thing is, the selected items are temporary just like an internet based shopping cart. It's nothing something that gets persisted once the application closes. Once the view is no longer in display, I can assume that the shopping cart is safe to discard. What's the best way to approach this? Since the user is essentially clicking on instances that map back to a Core Data entity .. should I setup a different persistence store such as in memory and add that store to my managed object context?

• Visaul Studio 2010, TlbImp generates .net 4.0 interops in 2.0 projects

  - by DJScrib

  In a C# project we add a reference to a COM object via the Add References setup pointing to a COM object which results in the IDE auto-generating the interop assembly. So this is fine and good, but we are building based on .net 3.5 SP1 aka CLR 2.0, and the generated interops are using the 4.0 CLR making them incompatiable. Is there a way to prevent this? I assume the other option is in our build script to try using tlbimp.exe with the /references parameter? to point to mscorlib v2.0? Anyhow, I'm hoping there's a flag somewhere to allow this.

  setup: hibernate 3.3, MySQL 5 I have an hibernate entity that have its PK generated using a sequence table. The annotation looks like this: @GenericGenerator(name = "SCENARIO_TABLE_GEN", strategy = "org.hibernate.id.enhanced.TableGenerator", parameters = { @Parameter(name = "initial_value", value = "5"), @Parameter(name = "force_table_use", value = "true"), @Parameter(name = "table_name", value = "SEQ_TABLE"), @Parameter(name = "value_column_name", value = "VALUE_COL"), @Parameter(name = "segment_column_name", value = "KEY_COL"), @Parameter(name = "segment_value", value = "SCENARIO") }) The problem is, that hibernate generated sequence table (SEQ_TABLE in my case, generated using hbm2ddl) does not have a primary keys. How do I tell hibernate that I want to have the primary key for the sequence table set on KEY_COL ?

• How do I run multiple objects through an IF statement in rails?

  - by codyvbrown

  I am creating an application that highlights user messages from a stream based on whether or not the user has been 'vouched'. It works fine if it's setup for a single author. For example controller: @vouch = Vouch.last.vouched_user_nickname view: <% if tweet.from_user == @vouch %> <div class="flit_message_containerh">.... But I'm having trouble doing it for multiple user nicknames. @vouch = Vouch.find(:all, :select => "vouched_user_nickname", :group => 'vouched_user_nickname' ) Any ideas would be greatly appreciated. I'm a rails noob.

• Safari 4.0.5 will not play any HTML5 (H.264) video

  - by axiomx11

  The html5test.com tells me that my browser does not support the <video> element, and when I try example page, I get the fallback message, usually "Your browser does not support HTML5 video." I know this should work in Safari. I am on Windows 7, 64-bit (running 32-bit Safari). Video works in Safari for everyone else in the office. (Windows 7 setup exactly like mine, Vista, OSX.) I have tries uninstalling, deleting all user preferences, and reinstalling. Anything else I should try?

• PODS + WP Theme

  - by Sharath

  So I managed to setup pods and create my custom tables. Now I want to revamp my theme so that it pulls data from the POD table. Doesn't seem to be working... This is what I did.. I have a Pod called 'project_type' with a name (string) and a code (string) field. Have also added 3 entries via the admin system. I made a copy of the default wordpress plugin and renamed it to myTheme and activated it. Inside index.php of myTheme, I removed all the default code.. and have just the POD specific code as shown below. <?php echo "Hello World"; $p = new Pod('project_type'); echo $p->getTotalRows(); ?> However, when I reload my page, only Hello World shows up? A bit new to Wordpress so kindly advice.

• In ASP.NET MVC, how does response.redirect work?

  - by Swoop

  I have used response.redirect in classic ASP and ASP.NET webforms. However, with MVC 2.0, I am running into something peculiar. I have a private method in a controller class that is used by multiple controller methods to help load and validate some information. This private method is setup to redirect if a problem is discovered to a generic error message page. The big problem I am noticing is that the calling controller class and page view attempt to complete rendering and loading before the redirect actually takes place. This is annoying in development because the View throws exceptions that I need to ignore before my generic error page finally loads. As mentioned above, I am used to the older model of response.redirect which prevented subsequent code on a page from being executed as the new page would then load. Any help or advice on redirects in MVC would be greatly appreciated.

• Hudson build fails when a user logs out of RDP session

  - by sjohnston

  We are using Hudson to build mixed C++/Java projects with an Ant script. It is running in Tomcat 6, on a Win XP virtual machine. I have noticed recently that when a user logs off the machine (from a remote desktop session), builds that are currently running tend to suddenly fail without an error message. Has anyone encountered anything similar or have an idea what might be causing this effect? I can post additional information about our setup if needed, I'm just not sure what's relevant in this case.

• How to debug PHP with netbeans and Xdebug

  - by Jon Winstanley

  I have recently tried to get going with Netbeans 6.5 after it rated so highly in the IDE review by Smashing magazine. http://www.smashingmagazine.com/2009/02/11/the-big-php-ides-test-why-use-oneand-which-to-choose/ My main reason for switching from Notepad++ is that I'd like to be able to debug my code and set through it. I have followed the instructions about how to install xdebug from both the vendor http://xdebug.org/ and the netbeans web site. http://www.netbeans.org/kb/docs/php/debugging.html#gettingReady but to no avail. How is it done, has anyone else got debugging working in netbeans? (My setup is: Windows XP, Wamp server 2.0, PHP 5, Netbeans 6.5.1)

• Using Forms authentication with remote auth system?

  - by chobo

  I am working on a website that uses a remote websites database to check for authentication (they are both share some database tables, but are separate website...) Right now I check the username and password against the remote websites account / member table, if there is a match I create a session. Questions: Is this secure? On authenticated pages I just check if a session of a specific type exists.Is it possible for someone to create an empty session or something that could bypass this? Is it possible to use Forms authentication with this setup? Right now if a user is authenticated I just get an object back with the username, email and id.

• PartCover and TeamCity

  - by jane doe

  I am using TeamCity to build via a solution file. I am attempting to get "PartCover" to work it. It is easy enough to point it to the partcover.exe, I am just unsure how to get team city to produce a proper report from the results of our nUnit test. I have added the a coverage.zip file to our setup and it is displaying the correct info under the artefacts tab, however under the code coverage tab the only info displayed is "Coverage by assembly" and nothing else. Any help or ideas would be great.

• Rails has_one vs belongs_to semantics

  - by Anurag

  I have a model representing a Content item that contains some images. The number of images are fixed as these image references are very specific to the content. For example, the Content model refers to the Image model twice (profile image, and background image). I am trying to avoid a generic has_many, and sticking to multiple has_one's. The current database structure looks like: contents - id:integer - integer:profile_image_id - integer:background_image_id images - integer:id - string:filename - integer:content_id I just can't figure out how to setup the associations correctly here. The Content model could contain two belongs_to references to an Image, but that doesn't seem semantically right cause ideally an image belongs to the content, or in other words, the content has two images. This is the best I could think of (by breaking the semantics): class Content belongs_to :profile_image, :class_name => 'Image', :foreign_key => 'profile_image_id' belongs_to :background_image, :class_name => 'Image', :foreign_key => 'background_image_id' end Am I way off, and there a better way to achieve this association?

• Process AJAX response with long runing tasks

  - by mpz

  I have long time task in controller action. I use delayed job for it. (Also in heroku it is good practice for perfomance - dyno must work for small time in each request) But my client need result of it work and users can wait on that task. It is more clear: no any addition models or records in it, simple view and js... I think about such way: On client run AJAX with very long timeout (5 min for example) Client make request to server as usual On controller in action1 def start_work (with delay work setup) i need NO any response to client After work performs (delay job finished) i need run new action2 with response to client Client recieve response after about 1-5 min It is possible?

• marshal Map<String, String> to .xml

  - by richardl

  If I have Map setup like: map.put("foo", "123"); map.put("bar", "456"); map.put("baz", "789"); then I want to do something like: for (String key : map.keySet().toArray(new String[0])) { // marshall out to .xml a tag with the name key and the // value map.get(key) } So what it will marshal out is something like: <map> <foo>123</foo> <bar>456</bar> <baz>789</baz> </map> Can I do this with some fancy JAXB annotations or is there something else that lends it self to dynamic element names? TIA

• Interacts with dialog/whiptail on early boot rcX.d stage?

  - by nm

  Hi buddies, I'm developing on Ubuntu based, actually I got one script in-charged on GUI(console) setup. It runs before another scripts (rcX.d) start. Currently, I installed this script on rc2.d and start earlier than other ones. But when run on real machine, I can't input any keystroke on "dialog --inputbox" or whiptail through shell script. Additionally, It runs well on my Virtual Machine (Virtual Box and Vmware), that's so strange! So, does anybody give some help or point me any clues for overcome this ? Thanks

• Visual artifacts on UIView rotation with tiled background image.

  - by Halbanonym

  I have an iPad app with a standard UIViewController/UIView setup - all rotations are allowed. The UIView draws some tiled image as background (the tile is 256*256 pixels): - (void)drawRect:(CGRect)rect { [[UIImage imageNamed: @"Background.png"] drawAsPatternInRect: rect]; } When I turn my iPad I can see that during the rotation the image pattern of the original orientation is scaled to fit the new orientation. Then - immediately after the animation is finished - the view redraws its background pattern with the final configuration which is unscaled. The switching from a scaled to an unscaled pattern looks a bit ugly. Is there a way to circumvent (or hide) this strecthing of the background pattern?

• How can I change ruby log level in unit tests based on context

  - by Stuart

  I'm new to ruby so forgive me if this is simple or I get some terminology wrong. I've got a bunch of unit tests (actually they're integration tests for another project, but they use ruby test/unit) and they all include from a module that sets up an instance variable for the log object. When I run the individual tests I'd like log.level to be debug, but when I run a suite I'd like log.level to be error. Is it possible to do this with the approach I'm taking, or does the code need to be restructured? Here's a small example of what I have so far. The logging module: #!/usr/bin/env ruby require 'logger' module MyLog def setup @log = Logger.new(STDOUT) @log.level = Logger::DEBUG end end A test: #!/usr/bin/env ruby require 'test/unit' require 'mylog' class Test1 < Test::Unit::TestCase include MyLog def test_something @log.info("About to test something") # Test goes here @log.info("Done testing something") end end A test suite made up of all the tests in its directory: #!/usr/bin/env ruby Dir.foreach(".") do |path| if /it-.*\.rb/.match(File.basename(path)) require path end end

• WordPress Custom Taxonomies

  - by Cameron

  I have the following code to build a custom taxonomy for my portfolio: add_action( 'init', 'create_pc_db_taxonomies', 0 ); function create_pc_db_taxonomies() { register_taxonomy( 'type', 'post', array( 'hierarchical' => true, 'label' => 'Type', 'query_var' => true, 'rewrite' => array( 'slug' => 'type' ) ) ); } I have created a portfolio category on my site (I removed the /category/ base) and have created some items and set the custom taxonomies against them. So I get the following setup: http://domain.com/portfolio/item1/ but what I want is for the taxonomy links to look like this: http://domain.com/portfolio/type/web and then this will show a list of portfolio items related to the that type. At the moment they are root like http://domain.com/type/web I have tried add portfolio/type as the taxonomy slug but it just creates a 404 but i'm pretty sure this is the wrong way of doing it anyways. Any help? Thanks

• Windows Service Fails on Launch

  - by Jeff

  I'm trying to write a windows service. It installs fine, but fails when I run it with the following exception. I've searched for the string "MyNewProgramService", but I can't find any conversions that would throw this error. I've also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring. I'm thinking it's somewhere in the auto-generated configuartion/setup code. Any ideas?
