  • cakePHP, multiple hasOne in a single model

    - by jason
    say you have 3 models : user, hair_color, and eye_color user hasOne hair_color user also hasOne eye_color however var $hasOne = 'hair_color'; var $hasOne = 'eye_color'; obviously wont work. So how do you implement many hasOne relationships in a single model? I assume the answer is in the cookbook, Im going over that area now, I suspect it has something to do with passing an array to $hasOne, but no example of doing this.

  • Supporting rotation sensors in Symbian across multiple devices in one executable

    - by magicbadger
    I'm puzzling my head as to how some application appear to support the couple of Rotational Sensor APIs for Symbian, specifically the Sensor API and the Sensor Framework (both the 5th ed. and the 3rd ed. FP2 backport). For example, I believe that Gravity will support rotation in N95 and also newer models from the same binary (could be wrong there...). If I use the Sensor Framework then my app will not install on an N95 (it gives me a System Error -1), whereas if I use the Sensor API (RRSensor) then it will only install on an N95 and no other phones. This is most likely due to the available libraries on those devices. I am trying to find some way of abstracting things such that I can use exactly the same binary for all devices. The only alternative I can see is trying to use ECOM plugins and then installing the relevant library using conditionals in my PKG file. Does anyone know of a better/easier way?

  • Ability to Choose From Multiple SQLite DBs for Iphone Application

    - by Mark
    I am working on the design and implementation of an iPhone application ( a newbie, but I am getting the hang of it) where a person can download specific contact information about teachers based on their majors. The information is currently on different edu websites. And I have exported the information into SQLite databases. Is it possible to develop the application that when it is first initiated, it can give the user the option of which particular SQLite database they want for their application? Or if not, would it be better to merge all the DBs into one DB, and allow the user the option of downloading specific information from the SQLite db. I see that the db's can be downloaded into an app, but have yet to find a solution where there can be an option to download from different SQLite dbs. Thanks!

  • Spring MVC managing multiple views with single controller

    - by Sudhir
    I am trying to implement order management module. There are different order types (approximately about 15). Each order has a seperate view. But the actions performed on UI are same irrespective of order type. Below is the structure of my DTO abstract class Order abstract class SecurityOrder extends Order abstract class TermDepositOrder extends Order ..... ..... ..... I am trying to implement a single controller capable of managing all views. Something similar to the one below: @Controller public class OrderController<F extends Order> { public F validate(F order) { } public F insert(F order) { } } I am not sure how spring mvc would be able to map request parameters properly to the order instance as it doesn't know which order instance to populate. Is it possible to achieve this with single controller or should I go with a controller for each order type and duplicate same code across all controllers?

  • eclipse + multiple checkouts of version-controlled projects

    - by Jason S
    We're using eclipse and svn. We keep the .project file in version control. The problem is, if you have more than one checked-out project (e.g. a trunk checkout and a feature branch) and would like them both to be available in Eclipse, you lose, because the .project files are identical and therefore can't both be imported into Eclipse. What's the right way to deal with this? (I'm mostly having to deal with this in TI's Code Composer v4 which uses an older version of eclipse, but I'm also going to need to do this in the regular Eclipse)

  • How to output multiple rows from an SQL query using the mysqli object

    - by Jonathan
    Assuming that the mysqli object is already instantiatied (and connected) with the global variable $mysql, here is the code I am trying to work with. class Listing { private $mysql; function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $this->listing = $result->fetch_array() or die('could not create object'); foreach ($this->listing as $key => $value) : $info[$key] = stripslashes(html_entity_decode($value)); endforeach; return $info; } } there are several hundred listings in the db and when I call $result-fetch_array() it places in an array the first row in the db. however when I try to call the object, I can't seem to access more than the first row. for instance: $listing_row = new Listing; while ($listing = $listing_row-getListingInfo()) { echo $listing[0]; } this outputs an infinite loop of the same row in the db. Why does it not advance to the next row? if I move the code: $this->listing = $result->fetch_array() or die('could not create object'); foreach ($this->listing as $key => $value) : $info[$key] = stripslashes(html_entity_decode($value)); endforeach; if I move this outside the class, it works exactly as expected outputting a row at a time while looping through the while statement. Is there a way to write this so that I can keep the fetch_array() call in the class and still loop through the records?

  • Using SQLAlchemy, how can I return a count with multiple columns

    - by Andy
    I am attempting to run a query like this: SELECT comment_type_id, name, count(comment_type_id) FROM comments, commenttypes WHERE comment_type_id=commenttypes.id GROUP BY comment_type_id Without the join between comments and commenttypes for the name column, I can do this using: session.query(Comment.comment_type_id,func.count(Comment.comment_type_id)).group_by(Comment.comment_type_id).all() However, if I try to do something like this, I get incorrect results: session.query(Comment.comment_type_id, Comment.comment_type, func.count(Comment.comment_type_id)).group_by(Comment.comment_type_id).all() I have two problems with the results: (1, False, 82920) (2, False, 588) (3, False, 4278) (4, False, 104370) Problems: The False is not correct The counts are wrong My expected results are: (1, 'Comment Type 1', 13820) (2, 'Comment Type 2', 98) (3, 'Comment Type 2', 713) (4, 'Comment Type 2', 17395) How can I adjust my command to pull the correct name value and the correct count?

  • Communication between Multiple Threads in a WPF Application

    - by Robert
    I'm creating a WPF application that uses a custom object to populate all the controls. The constructor of that object is initiated by an EventHandler that waits for an API. The problem I'm having is when I try to access any information from that object using a button for example, it returns an error saying "The calling thread cannot access this object because a different thread owns it". I'm assuming this is because the EventHandler creates a new thread which doesn't allow the Main Thread to have access to it. Any ideas on how to get around this? I'm basically having the error "The calling thread cannot access this object because a different thread owns it" when trying to get or set a CollectionViewSource.

  • ODBC - multiple connections from one app to the same data source

    - by Marcin K
    I vaguely remember reading somewhere (in MSDN ODBC documentation?) that one application cannot make more than one connection to a single data source. It seemed to me that I need one connection that all the threads of the application will have to share. I was trying to look this information up, but I can't seem to find it anymore. Does anyone know/remember how this works? It all might become a problem in our app, since some of its threads will dynamically connect to data sources of their choice. I don't want to see random connection errors if two of them will connect at the same time to one source, so I wanted to double check this info.

  • How to instantiate a Singleton multiple times?

    - by Sebi
    I need a singleton in my code. I implemented it in Java and it works well. The reason I did it, is to ensure that in a mulitple environment, there is only one instance of this class. But now I want to test my Singleton object locally with a Unit test. For this reason I need to simulate another instance of this Singleton (the object that would be from another device). So is there a possiblity to instantiate a Singleton a second time for testing purpose or do I have to mock it? I'm not sure, but I think it could be possible by using a different class loader?

  • Query with multiple IN-statements but without the cartesian product

    - by Janne
    How could I make this kind of query e.g. in MySQL SELECT * FROM Table t WHERE t.a IN (1,2,3) AND t.b IN (4,5,6) AND t.c IN (7,8,9) ... so that the result would contain only the three rows: t.a|t.b|t.c ---+---+--- 1 | 4 | 7 2 | 5 | 8 3 | 6 | 9 The above query of course returns all the combinations of the values in the IN clauses but I would like to get just the ones where the first elements of each tuple match, second elements of each tuple match and so on. Is there any efficient way to do this? By the way is there some common term for this kind of query or concept? I'm having hard time coming up with the question's title because I can't put this into words..

  • Problem using GDI+ with multiple threads (VB.NET)

    - by Joe B
    I think it would be best if I just copy and pasted the code (it's very trivial). Private Sub Main() Handles MyBase.Shown timer.Interval = 10 timer.Enabled = True End Sub Private Sub Form1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint e.Graphics.DrawImage(image, 0, 0) End Sub Private Sub tick() Handles timer.Elapsed Using g = Graphics.FromImage(image) g.Clear(Color.Transparent) g.DrawLine(Pens.Red, 0 + i, 0 + i, Me.Width - i, Me.Height - i) End Using Me.Invalidate() End Sub An exception, "The object is currently in use elsewhere", is raised during the tick event. Could someone tell me why this happens and how to solve it? Thanks.

  • Text replacement for multiple script/config files

    - by user343804
    I am doing some sort of science with a combination of Python, bash scripts and configuration files with weird syntaxes from old C programs. To run different tests, I have to tune (open text file, edit and save) a number of these files, but it is getting harder and harder to remember which files to edit. Also, the tasks are very repetitive and I end having a bunch of comment lines, switching on and off the settings for a specific run. I dream of a tool that can keep a list of files (regardless of the file format) and allow me to centrally choose from a predefined list of "profiles", taking care of editing the script/config files. For example lets say I have a config and script file: config.cfg var1 = 1.0 #var1 = 1.5 script.sct function(200.0) #function(300.0) I would like to instead have auxiliary text files: config.cfg.tem var1 = $$var1$$ script.sct.tem function($$par1$$) and in a central script or even better, a GUI, just switch from profile1 (e.g. var1=1.0,par1=200.0) to profile2 (e.g. var1=1.5,par1=300.0), and the tool to automatically update the text files. Any idea if such a tools exists?

  • Loading jQuery multiple times in the same page

    - by Winaji
    I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

  • Support for multiple domains/subdomains in Rails

    - by thefactor
    I have a Rails app that has a similar setup to Tumblr, that is, you can have either: (1) Subdomain hosting (your-username.myapp.com) (2) Domain hosting (your-username.com) Both would forward to a personalized website for that user, created with my application. How can I accomplish this in Rails? I have been able to get (1) working with subdomain-fu, but I'm not sure how to get (2) working. Any pointers (plugins, gems, tutorials), etc. would be greatly helpful, I can't seem to find any. Thanks!

  • How to move many files in multiple different directories (on Linux)

    - by user1335982
    My problem is that I have too many files in single directory. I cannot "ls" the directory, cos is too large. I need to move all files in better directory structure. I'm using the last 3 digits from ID as folders in reverse way. For example ID 2018972 will gotta go in /2/7/9/img_2018972.jpg. I've created the directories, but now I need help with bash script. I know the IDs, there are in range 1,300,000 - 2,000,000. But I can't handle regular expressions. I wan't to move all files like this: /images/folder/img_2018972.jpg -> /images/2/7/9/img_2018972.jpg I will appreciate any help on this subject. Thanks!
