• Specifying Entire Path As Optional Rails 3.0.0

  - by Kevin Sylvestre

  I want to create a Rails 3 route with entirely optional parameters. The example route is: match '(/name/:name)(/height/:height)(/weight/:weight)' => 'people#index' The route works if I specify it as: match '/people(/name/:name)(/height/:height)(/weight/:weight)' => 'people#index' But I want to have this as the root URL. Thanks.

• Problems using Custom Layout in XML

  - by Kevin

  I've created a new GridLayout class that I want to use in an XML File. The class is in another project. I've created the attrs.xml file in the other project with my properties but when the constructor gets called with the AttributeSet, none of the values are set. In my xml for my screen layout, I refer to the layout with the following: xmlns:gridLayout="@com.mastertechsoftware.AndroidUtil:http://schemas.android.com/apk/res/com.mastertechsoftware.AndroidUtil" Not sure if that is right. I have the attrs.xml file being compiled to R.java in com/mastertechsoftware/AndroidUtil. All the right styleable values are there. In my constructor, I use: TypedArray a = c .obtainStyledAttributes(attrs, R.styleable.GridLayout); this.numRows = a.getInt(R.styleable.GridLayout_numRows, -1); Nothing comes back (-1 does but that means nothing is there) If I use int n = a.getIndexCount(); I get 0.

• 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 )

• 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.

• 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?

• Instantiating class by string using PHP 5.3 namespaces

  - by Kevin

  I can't get around an issue instantiating a new class by using a string variable and PHP 5.3. namespaces. For example, this works; $class = 'Reflection'; $object = new $class(); However, this does not; $class = '\Application\Log\MyClass'; $object = new $class(); A fatal error gets thrown stating the class cannot be found. However it obviously can be instantiated if using the FQN i.e.; $object = new \Application\Log\MyClass; I've found this to be aparrent on PHP 5.3.2-1 but not not in later versions. Is there a work around for this?

• EJB3.1 logout doesn't work

  - by Kevin

  Hello, I've got a problem with the authentication features of EJB3.1: With this code in a Servlet v3: log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); log.info("===^==="); request.logout() ; log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); request.authenticate(response) ; log.info("===v==="); log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); I would always expect to see the Username/login windows, because of the logout() function. Instead, it seems to be a 'cache' mechanism which repopulate the credential and cancel my logout ... Admin BASIC ===^=== null null ===v=== Admin BASIC is it a problem with my firefox, or something I'm missing in the Servlet code? Thanks

• 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?

• Is there a Veil-like plug-in for MySQL?

  - by Kevin

  We have a MySQL database and would like to have row-level security implemented at the database level. I have been playing with the Veil plug-in for PostgreSQL and like what it does. Is there something similar for MySQL so we do not have to convert over to PostgreSQL?

• wxPython formatting questions

  - by Kevin

  I have an app I was working on to learn more about wxPython( I have been primarily been a scripter ). I forgot about it now I am opening it back up. It's a screen scraper, and I have it working almost the way I want it, going to build a regex parser to strip out the links in every scrape that I don't need. The questions I have are this. In it current state, if I check more than one site, it goes out and scrapes, and returns it in separate windows, the for:each section in the Clicked function. I want to put them in a frame, in the window, altogether. I also want to know if I can take the list they are read into and send it to a checklist, so someone could check off separate items, I want to build a save function and keep certain ones. In regards to a save function, I want to keep saved checks, are there calls to the widgets to save their states? I know it's a lot, but thanks for the help.

• Adding text labels to sliders in iPhone Settings application

  - by Kevin L.

  When configuring a Settings.bundle as part of an iPhone application bundle, it's trivial to add minimum and maximum value images to sliders (PSSliderSpecifier), but not simple maximum and minimum text labels. http://developer.apple.com/iPhone/library/documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSSliderSpecifier.html iPhone gurus: Is anyone aware of a simple means to apply text labels to these sliders for use within the Settings application (therefore, no slider subclassing shenanigans; it all has to be done via a plist)? I suppose I could just use an image of the label but...ew. Bonus points if there's a way to show the current value of a slider in some sort of number format.

• Ideas on limiting content to single printed page?

  - by James Skidmore

  I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

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

  - by James Skidmore

  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!

• 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!

• Recommend ONE favorite SSIS component that does SFTP/FTPS

  - by Kevin Fairchild

  Sometimes normal FTP doesn't quite cut it... When you need to do secure FTP via SSIS packages, what ONE product would you recommend? Before answering, please see if someone has already suggested the same thing and, if so, vote it up. NOTE: Ideally, it needs to handle both SSH and SSL FTP connections, but I'd consider two separate components if it makes the most sense....

• 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?

• Is there any convinient way that i can deepclone 'style' instance in silverlight?

  - by Kevin Yang

  if a style is used, it can not be modified agaign. so i need a clone method. but its hard to implement. what i want to do is implementing a cascading 'style' mechanism. for example, i set two style to the same frameworkelement. the same property of latter style will override the former one, while the different property remain unchanged. but if i set the style property of the frameworkelement twice directly, the 1st style will be gone. so i use the baseon property of style class to do that. but now come across another problem, the style can not be modified after it's been set to a frameworkelement. so now i need a clone method.

• 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.

• Delete/move a UITableView row that's attached to a web service.

  - by Kevin L.

  Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

• 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! =)
