• What does the length attribute do when set on the @Column JPA annontation?

  - by James McMahon

  What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

• Codeigniter PHP - loading a view at an anchor point

  - by James Billings

  I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion: $this->load->view('template',$data); however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter? I can't use the codeigniter redirect(); function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like: $this->redirect(); which solves the problem because you keep the object. I've tried using: $this->index() within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from: $this->item($labs) but when I use this it get stuck in a loop Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill. cheers.

• How do I set bash environment variables from a script?

  - by James A. Rosen

  I have some proxy settings that I only occasionally want to turn on, so I don't want to put them in my ~/.bash_profile. I tried putting them directly in ~/bin/set_proxy_env.sh, adding ~/bin to my PATH, and chmod +xing the script but though the script runs, the variables don't stick in my shell. Does anyone know how to get them to stick around for the rest of the shell session?

• Loading a entity IDs CSV column as hydrated entities in NHibernate

  - by James L

  I have a number of database table that looks like this: EntityId int : 1 Countries1: "1,2,3,4,5" Countries2: "7,9,10,22" I would like to have NHibernate load the Country entities identifed as 1,2,3,4,5,7,9 etc. whenever my EntityId is loaded. The reason for this is that we want to avoid a proliferation of joins, as there are scores of these collections.

• Sum up values in SQL once all values are available

  - by James Brown

  I have events flowing into a MySQL database and I need to group and sum the events to transactions and store away into another table. The data looks like: +----+---------+------+-------+ | id | transid | code | value | +----+---------+------+-------+ | 1 | 1 | b | 12 | | 2 | 1 | i | 23 | | 3 | 2 | b | 34 | | 4 | 1 | e | 45 | | 5 | 3 | b | 56 | | 6 | 2 | i | 67 | | 7 | 2 | e | 78 | | 8 | 3 | i | 89 | | 9 | 3 | i | 90 | +----+---------+------+-------+ The events arrive in batches and I would like to create the transaction by summing up the values for each transid, like: select transid, sum(value) from eventtable group by transid; but only after all the events for that transid have arrived. That is determined by the event with the code e (b for the beginning, e for the end and i for varying amount of intermediates). Being a novice in SQL, how could I implement the requirement for the existance of the end code before the summing?

• How to use a class as the base, but hide the class type publically?

  - by James

  I am currently just exposing the properties through a generic interface e.g. public interface IBaseClass { int ID { get; set; } } internal class MyBaseClass : IBaseClass { public MyBaseClass() { } public int ID { get; set; } } public class MyExposedClass : IBaseClass { private MyBaseClass _base = new MyBaseClass(); public int ID { get { return _base.ID; } set { _base.ID = value; } } } Then in my main application I can do: IBaseClass c = new MyExposedClass(); c.ID = 12345; But can't do: MyBaseClass b = new MyBaseClass(); This is my desired behaviour. However, I was just wondering if this is the correct approach? Or if there was a better way?

• Exclude category from main RSS feed, but not all feeds

  - by jamEs

  I've got a blog that supplies content to multiple MailChimp newsletters via RSS. The first newsletter works fine, but the second I'm having issues with. The issue I have is that the second newsletter has "hidden" content. This content isn't meant for wide consumption, so it doesn't appear on the frontpage, but is accessible elsewhere on the site. The snafu with this is that not all of this content is hidden, just some of it, while other pieces of content for this newsletter could overlap with the first newsletter. This obviously makes excluding everything problematic, as they could be assigned multiple categories, some of which I wouldn't want hidden. The issue I'm running into is that I have a way to exclude this content from the frontpage, but not from the main RSS feed. I'm using WP Hide Post for this, which allows me to exclude from feed, which in turn removes it from all feeds, including the ones that feed the newsletter. I'm currently using /feed?cat=XXX to reference these feeds. Is there a way to make it so category feeds still work, just the main /feed RSS would exclude it?

• How do you program a custom WordPress plug-in?

  - by James

  I have seen several WordPress plug-ins for adding a "quote of the day" feature (or something similar) to your blog. How do you create a customized one? I'm looking for something that will pull a daily entry from a list/database of my creation. I apologize if my question is not detailed enough. Still a newbie with WordPress. PART 2: Thanks for your prompt and on-point responses. With your responses and some additional research, I'm able to fine-tune my question. What I wish to accomplish is something similar to Amazon's Deal of the Day widget. Except, in my case, it will simply be a title and a corresponding link. My presumption is that I will set up a database and (using php or something similar) have the information drawn from the database and displayed in my WP sidebar. Additionally, I forgot to mention the time element. I want the displayed info to update once a day, at or around the same time each day. Any ideas? Thanks again. I'm so glad I found stackoverflow.

• If I cast an IQueryable as an IEnumerable then call a Linq extension method, which implementation gets called?

  - by James Morcom

  Considering the following code: IQueryable<T> queryable; // something to instantiate queryable var enumerable = (IEnumerable<T>) queryable; var filtered = enumerable.Where(i => i > 3); In the final line, which extension method gets called? Is it IEnumerable<T>.Where(...)? Or will IQueryable<T>.Where(...) be called because the actual implementation is still obviously a queryable? Presumably the ideal would be for the IQueryable version to be called, in the same way that normal polymorphism will always use the more specific override. In Visual Studio though when I right-click on the Where method and "Go to Definition" I'm taken to the IEnumerable version, which kind of makes sense from a visual point-of-view. My main concern is that if somewhere in my app I use Linq to NHibernate to get a Queryable, but I pass it around using an interface that uses the more general IEnumerable signature, I'll lose the wonders of deferred database execution!

• PHP memory exhausted when running through thousands of records

  - by James Skidmore

  I'm running the following code over a set of 5,000 results. It's failing due to the memory being exhausted. foreach ($data as $key => $report) { $data[$key]['data'] = unserialize($report['serialized_values']); } I know I can up the memory limit, but I'd like to run this without a problem instead. I'm not going to be able to keep upping the memory forever. EDIT The $data is in this format: [1] => Array ( [0] => 127654619178790249 [report_id] => 127654619178790249 [1] => 1 [user_id] => 1 [2] => 2010-12-31 19:43:24 [sent_on] => 2010-12-31 19:43:24 [3] => [fax_trans_id] => [4] => 1234567890 [fax_to_nums] => 1234567890 [5] => ' long html string here', [html_content] => 'long html string here', [6] => 'serialization_string_here', [serialized_values] => 'serialization_string_here', [7] => 70 [id] => 70 )

• Retrieve POST data without knowing exact number of fields

  - by James

  Hi all! I'm creating an online poll from scratch which will be held in a database. I'm working on getting a system set up so someone can create a new poll. I will be having the user fill out a simple HTML form with the Questions and Answers (there may be several answers). The user will be able to add multiple questions and multiple answers for each question. As the total number of questions and answers will be decided by the user, I need to create some clever PHP to cater for this - however many there are. When dealing with a static number of questions, it's simple. But I'm having trouble thinking of a way to get all the POST data into individual PHP variables so I can process them. I was thinking of using a foreach loop, anyone got any ideas? Sorry for the long winded description! If anyone needs anything clarified, I'd be happy to do so. My problem is that I can't get my head around how to deal with the POST values when I don't know exactly which element of the array will contain what. If things were static with a set number of questions and answers, I'd know $_POST[0] was Question1, etc Thank you! =)

• Designing DAOs for data sources other than a database

  - by James P.

  Hi, Until now I've been used to using DAOs to retrieve information from databases. Other sources of data are possible though and I'm wondering if and how the pattern could be applied in general. For example, I'm now working on an application that fetches XML on the web. The XML file could be considered as a data source and the actual fetching is similar in principle to a database request. I'm not quite sure how the DAO could be structured though. Any views on the subject are welcome.

• PHP script isn't receiving income POST data from a remote form

  I have a PHP script that uses standard POST variables like $_POST['email']. When a form on a remote server sends a POST request to my script, it doesn't receive the POST data at all. It's not in $_REQUEST either. Thanks for any help!

• Undefined test not working in javascript.

  - by James South

  I'm getting the error 'foo' is undefined. in my script when i test my function with an undefined parameter. As far as I understand, This shouldn't be happening. My calling code: //var foo var test = peachUI().stringIsNullOrEmpty(foo) ; My function (part of a larger framework). stringIsNullOrEmpty: function (testString) { /// <summary> /// Checks to see if a given string is null or empty. /// </summary> /// <param name="testString" type="String"> /// The string check against. /// </param> /// <returns type="Boolean" /> var $empty = true; if (typeof testString !== "undefined") { if (testString && typeof testString === "string") { if (testString.length > 0) { $empty = false; } } } return $empty; } Any ideas? Please note. I've had a good read of other similar questions before posting this one.

However, this doesn't seem to work in the form. What should I be using?

• MATLAB pdist function

• Help with doctype issues

  - by James

  Hi I am having issues making my footer stick to the bottom of the page in all browsers. I have the following document structure: <html> <head> </head> <body> <div id="wrapper"> <div id="header"> <ul> <li>home</li> </ul> </div> <div class="expander"></div> </div> <div id="footer" class="expander"> </div> </body> </html> Relevant CSS is: body { margin: 0; height: 100%; } #wrapper { min-height: 100%; height: auto !important; height: 100%; margin: 0 auto -116px; } .expander { height: 116px; } #footer { width: 100%; } #header ul { list-style: none outside none; clear: both; margin: 0; } #header li { margin: 0; margin-right: 20px; padding: 0; display: inline-block; height: 85px; padding-top: 20px; margin-bottom: -20px; } When used without any doc type, the page renders as I intend it to in Chrome and Firefox. In IE8, however, the list item tabs are on separate lines When I add an XHTML doctype, the page renders correctly in IE8 except the footer is not drawn at the bottom of the page in IE8, Chrome or Firefox, i.e. the footer sits directly below the menu bar. Example doctype: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> What am I doing wrong?
