  • Rails 3: Validate combined values

    - by Cimm
    In Rails 2.x you can use validations to make sure you have a unique combined value like this: validates_uniqueness_of :husband, :scope => :wife In the corresponding migration it could look like this: add_index :family, [:husband, :wife], :unique => true This would make sure the husband/wife combination is unique in the database. Now, in Rails 3 the validation syntax changed and the scope attribute seems to be gone. It now looks like: validates :husband, :presence => true Any idea how I can achieve the combined validation in Rails 3? The Rails 2.x validations still work in Rails 3 so I can still use the first example but it looks so "old", are there better ways?

  • Calling and writing jquery/javascript functions

    - by Ankur
    I think I have not got the syntax correct for writing a javascript function and calling it to assign its return value to a variable. My function is: getObjName(objId){ var objName =""; $.ajax( { type : "GET", url : "Object", dataType: 'json', data : "objId="+objId, success : function(data) { objName = data; } }); return objName; } I am trying to call it and assign it to a variable with: var objName = getObjName(objId); However Eclipse is telling me that "the function getObjName(any) is undefined"

  • MSDTC Distributed Transaction Coordinator Enabling

    - by Curtis White
    I've a web server and a separate SQL server. I'm trying to use transaction scope to ensure that SQL queries are completed with my linq queries. I wrap everything with this using (TransactionScope scope = new TransactionScope()) I want to know where I need to install DTC. Do I need to install it on the IIS 7.5 box AND the SQL server? Do I need to unblock some ports? Are there any security risk in doing so? I've setup this up once before but don't remember how. If I can't get access to DTC then is there any other way to ensure a lINQ and sql query is atomic?

  • Spring MVC - JSP - Place to Store Environment Specific Constants

    - by jboyd
    Where in the Spring-MVC/JSP application would you store things that need to be accessed by both the controllers and views such as environment specific base_url's, application ids to be used in javascript and so on? I've tried creating an application scoped bean and then at the top of my JSPs, but that doesn't seem to be working. <!-- Environment --> <bean id="myEnv" class="com.myapp.MyAppEnvironment" scope="application"> <property name="baseUrl" value="http://localhost:8080/myapp/"/> <property name="videoPlayerId" value="234346565"/> </bean> And using it in the following manner <jsp:useBean id="myEnv" scope="application" type="com.myapp.MyAppEnvironment"/>

  • Why would var be a bad thing?

    - by Spoike
    I've been chatting with my colleagues the other day and heard that their coding standard explicitly forbids them to use the var keyword in C#. They had no idea why it was so and I've always found implicit declaration to be incredibly useful when coding. I've never had any problems finding out what type the variable was (you only hover over the variable in VS and you'll get the type that way). Does anyone know why it would be a bad idea to use the var keyword in C#?

  • C# Async call garbage collection

    - by Troy
    Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? internal MyClass { public void OnMyButtonClicked() { var wcfClient = new WcfClient(); wcfClient.SomeMethodFinished += OnMethodCompleted; wcfClient.SomeMethodAsync(); } private void OnMethodCompleted(object sender, EventArgs args) { //Do something with the result //After this method does the subscription to the event //fall out of scope for garbage collection? } } Will I run into problems if I call the function again and create another subscription? Thanks in advance to anyone who responds.

Does anyone know if what I'm wanting is possible? Thanks.

  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • HTML_Template_IT and wordpress

    - by David Ryder
    I want to use PEAR's HTML_Template_IT in one of my Wordpress page templates so I can separate the HTML from the PHP. I got it working, except I am not sure about one thing. Wordpress's built-in function get_header() actually echo's HTML - so I can't technically set it as a template variable. Is this considered acceptable or is there another way to put the contents of get_header() in a variable? Thanks!

  • Will the Order of my Associative Array be maintained from PHP to Javascript?

    - by Colin
    In PHP I'm running a mysql_query that has an ORDER BY clause. I'm then iterating through the results to build an associative array, with the row_id as the key. Then, I'm calling json_encode on that array and outputting the result. This page is loaded with AJAX, and defined in a Javascript variable. When I iterate through that Javascript variable, will I still have the order that was returned from the mysql_query?

  • Tridion Core Service - Transaction roll back isnt working

    - by Tamir Lahav
    We are using the core service in ASP.NET custom page in order to create pages and components and sevenral updates (checkout,save and chekin). we want those operations to work in transaction, we tried to implement it acording to some examples over the net. However we didn't succeded operating the rollback. It seems that the operation are immediately performed without waiting for the comit . The code we used for simple check out - roll back operation for example is TransactionOptions txOptions = new TransactionOptions { IsolationLevel = IsolationLevel.ReadCommitted }; using (TransactionScope scope = new TransactionScope( TransactionScopeOption.Required, txOptions)) { using (CoreService2010Client m_client = new CoreService2010Client()) { PageData pp = m_client.CheckOut("tcm:309-36311-64", false, new ReadOptions()) as PageData; } scope.Dispose(); } We also added this recomended configuration to the web config bindings section What are we missing ?

  • How to combine a list of choices to determine which select statement

    - by Larry
    I have a mysql db and am using php 5.2 What I am trying to do is offer a list of options for a person to select (only 1). The chosen option will cause a select, update, or delete statement to be ran. The results of the statement do not need to be shown, although, showing the old and then the new would be nice (no problems with that part tho'.). Pseudo-Code: Assign $choice = 0 Check the value of $choice // This way, if it = 100, we do a break Select a Choice:<br> 1. Adjust Status Value (+60) // $choice = 1<br> 2. Show all Ships <br> // $choice = 2 3. Show Ships in Port <br> // $choice = 3 ... 0. $choice="100" // if the value =100, quit this part Use either case (switch) or if/else statements to run the users choice1 If the choice is 1, then run the "Select" statement with the variable of $sql1 -- "SELECT .... If the choice is 2, then run the "Select" statement with the variable of $sql2 --- SELECT * FROM Ships If the choice is 3, then run the "Select" statement with the variable of $sql3 <br> .... If the choice is 0, then we are done. I figured the (3) statements would be assigned in php as: $sql1="...". $sql2="SELECT * FROM Ships" $sql3="SELECT * FROM Ships WHERE nPort="1" My idea was to use the switch statement, but got lost on it. :( I would like the options to be available over and over again, until a variable ($choice) is selected. In which case, this particular page is done and goes back to the "Main Menu"? The coding and display, if I use it, I can do. Just not sure how to write the way to select which one I want. It is possible that I would run all of the queries, and other times, only one, so that is why I would like the choice. An area I get confused in is the proper forms to use such as -- ' ' " " and ...?? Not sure the # of options I will end up with, but it will be more than 5 but less than 20 / page. So if I get the system down for 2-3 choices, I can replicate it for as many as I may need. And, as always, if a better way exists, I am willing to try it. Thanks again... Larry
