  • How do I relate tables with different foreign key names in Kohana ORM?

    - by Matt H
    I'm building a Kohaha application to manage sip lines in asterisk. I'm wanting to use ORM but I'm wondering how do relate certain tables that are already well established. e.g. the table sip_lines looks like this. +--------------------+------------------+------+-----+-------------------+-----------------------------+ | Field | Type | Null | Key | Default | Extra | +--------------------+------------------+------+-----+-------------------+-----------------------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | sip_name | varchar(80) | NO | UNI | NULL | | | displayname | varchar(48) | NO | | NULL | | | line_num | varchar(10) | NO | MUL | NULL | | | model | varchar(12) | NO | MUL | NULL | | | mac | varchar(16) | NO | MUL | NULL | | | areacode | varchar(6) | NO | MUL | NULL | | | per_line_astpp_acc | tinyint(1) | NO | | 0 | | | play_warning | tinyint(1) | NO | | 0 | | | callout_disabled | tinyint(1) | NO | | 0 | | | notes | varchar(80) | NO | | NULL | | | last_update | timestamp | NO | | CURRENT_TIMESTAMP | on update CURRENT_TIMESTAMP | +--------------------+------------------+------+-----+-------------------+-----------------------------+ sip_buddies is this: +----------------+------------------------------+------+-----+-----------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------------------------+------+-----+-----------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(80) | NO | UNI | | | | host | varchar(31) | NO | | | | | | | lastms | int(11) | NO | | 0 *** snip *** +----------------+------------------------------+------+-----+-----------+----------------+ The two tables are actually related as sip_lines.sip_name = sip_buddies.name How do I relate them in Kohana ORM as this wouldn't be quite right would it? <?php defined('SYSPATH') or die('No direct script access.'); /* A model for all the account information */ class Sip_Line_Model extends ORM { protected $has_one = array("sip_buddies"); } ?> EDIT: Actually, it'd be fair to say that these tables are not properly related with foreign keys! doh. EDIT: Looks like Kohana ORM is not that flexible. ORM is probably not the way to go and works best for completely new projects where the data model can be altered. The reason being that the key names must follow a specific naming convention or else they won't relate in Kohana.

  • Method collect on Scala 2.7

    - by Brian Heylin
    I'm looking for a collect method in scala 2.7 but I can't seem to find an applicable call. Is there something equivalent to collect that I can use in scala? To be clear I'm looking to filter elements from a list and map those filtered to a new type.

  • jQuery "Autocomplete" plugin is messing up the order of my data

    - by Max Williams
    I'm using Jorn Zaefferer's Autocomplete plugin on a couple of different pages. In both instances, the order of displayed strings is a little bit messed up. Example 1: array of strings: basically they are in alphabetical order except for General Knowledge which has been pushed to the top: General Knowledge,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: General Knowledge,Geography,Art and Design,Business Studies,Citizenship,Design and Technology,English,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Note that Geography has been pushed to be the second item, after General Knowledge. The rest are all fine. Example 2: array of strings: as above but with Cross-curricular instead of General Knowledge. Cross-curricular,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: Cross-curricular,Citizenship,Art and Design,Business Studies,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Here, Citizenship has been pushed to the number 2 position. I've experimented a little, and it seems like there's a bug saying "put things that start with the same letter as the first item after the first item and leave the rest alone". Kind of mystifying. I've tried a bit of debugging by triggering alerts inside the autocomplete plugin code but everywhere i can see, it's using the correct order. it seems to be just when its rendered out that it goes wrong. Any ideas anyone? max EDIT - reply to Clint Thanks for pointing me at the relevant bit of code btw. To make diagnosis simpler i changed the array of values to ["carrot", "apple", "cherry"], which autocomplete re-orders to ["carrot", "cherry", "apple"]. Here's the array that it generates for stMatchSets: stMatchSets = ({'':[#1={value:"carrot", data:["carrot"], result:"carrot"}, #3={value:"apple", data:["apple"], result:"apple"}, #2={value:"cherry", data:["cherry"], result:"cherry"}], c:[#1#, #2#], a:[#3#]}) So, it's collecting the first letters together into a map, which makes sense as a first-pass matching strategy. What i'd like it to do though, is to use the given array of values, rather than the map, when it comes to populating the displayed list. I can't quite get my head around what's going on with the cache inside the guts of the code (i'm not very experienced with javascript).

  • Guidelines to an Iterator Class

    - by isurulucky
    Hi, I have a Red Black tree implemented in c++. It supports the functionality of a STL map. Tree nodes contain keys and the values mapped. I want to write an iterator class for this, but I'm stuck with how to do it. Should I make it an inner class of the Tree class? Can anyone give me some guidelines on how to write it + some resources?? Thank You!!

  • when to use the abstract factory pattern?

    - by hguser
    Hi: I want to know when we need to use the abstract factory pattern. Here is an example,I want to know if it is necessary. The UML THe above is the abstract factory pattern, it is recommended by my classmate. THe following is myown implemention. I do not think it is necessary to use the pattern. And the following is some core codes: package net; import java.io.IOException; import java.util.HashMap; import java.util.Map; import java.util.Properties; public class Test { public static void main(String[] args) throws IOException, InstantiationException, IllegalAccessException, ClassNotFoundException { DaoRepository dr=new DaoRepository(); AbstractDao dao=dr.findDao("sql"); dao.insert(); } } class DaoRepository { Map<String, AbstractDao> daoMap=new HashMap<String, AbstractDao>(); public DaoRepository () throws IOException, InstantiationException, IllegalAccessException, ClassNotFoundException { Properties p=new Properties(); p.load(DaoRepository.class.getResourceAsStream("Test.properties")); initDaos(p); } public void initDaos(Properties p) throws InstantiationException, IllegalAccessException, ClassNotFoundException { String[] daoarray=p.getProperty("dao").split(","); for(String dao:daoarray) { AbstractDao ad=(AbstractDao)Class.forName(dao).newInstance(); daoMap.put(ad.getID(),ad); } } public AbstractDao findDao(String id) {return daoMap.get(id);} } abstract class AbstractDao { public abstract String getID(); public abstract void insert(); public abstract void update(); } class SqlDao extends AbstractDao { public SqlDao() {} public String getID() {return "sql";} public void insert() {System.out.println("sql insert");} public void update() {System.out.println("sql update");} } class AccessDao extends AbstractDao { public AccessDao() {} public String getID() {return "access";} public void insert() {System.out.println("access insert");} public void update() {System.out.println("access update");} } And the content of the Test.properties is just one line: dao=net.SqlDao,net.SqlDao So any ont can tell me if this suitation is necessary?

  • Code refactoring homework?

    - by Hira
    This is the code that I have to refactor for my homework: if (state == TEXAS) { rate = TX_RATE; amt = base * TX_RATE; calc = 2 * basis(amt) + extra(amt) * 1.05; } else if ((state == OHIO) || (state == MAINE)) { rate = (state == OHIO) ? OH_RATE : MN_RATE; amt = base * rate; calc = 2 * basis(amt) + extra(amt) * 1.05; if (state == OHIO) points = 2; } else { rate = 1; amt = base; calc = 2 * basis(amt) + extra(amt) * 1.05; } I have done something like this if (state == TEXAS) { rate = TX_RATE; calculation(rate); } else if ((state == OHIO) || (state == MAINE)) { rate = (state == OHIO) ? OH_RATE : MN_RATE; calculation(rate); if (state == OHIO) points = 2; } else { rate = 1; calculation(rate); } function calculation(rate) { amt = base * rate; calc = 2 * basis(amt) + extra(amt) * 1.05; } How could I have done better? Edit i have done code edit amt = base * rate;

  • Business Objects - Containers or functional?

    - by Walter
    Where I work, we've gone back and forth on this subject a number of times and are looking for a sanity check. Here's the question: Should Business Objects be data containers (more like DTOs) or should they also contain logic that can perform some functionality on that object. Example - Take a customer object, it probably contains some common properties (Name, Id, etc), should that customer object also include functions (Save, Calc, etc.)? One line of reasoning says separate the object from the functionality (single responsibility principal) and put the functionality in a Business Logic layer or object. The other line of reasoning says, no, if I have a customer object I just want to call Customer.Save and be done with it. Why do I need to know about how to save a customer if I'm consuming the object? Our last two projects have had the objects separated from the functionality, but the debate has been raised again on a new project. Which makes more sense? EDIT These results are very similar to our debates. One vote to one side or another completely changes the direction. Does anyone else want to add their 2 cents? EDIT Eventhough the answer sampling is small, it appears that the majority believe that functionality in a business object is acceptable as long as it is simple but persistence is best placed in a separate class/layer. We'll give this a try. Thanks for everyone's input...

  • Adding an HTTP Header to the request in a servlet filter

    - by Mason
    I'm integrating with an existing servlet that pulls some properties out of the HTTP header. Basically, I'm implementing an interface that doesn't have access to the actual request, it just has access to a map of k-v for the HTTP headers. I need to pass in a request parameter. The plan is to use a servlet filter to go from parameter to header value but of course the HttpServletRequest object doesn't have an addHeader() method. Any ideas?

  • Control Oracle Forms with outside program

    - by user256893
    I work at a company that uses the Forms based Oracle 11i. A lot of employees complain of the redundancy of data entry and I want to write a program that will ease some of that pain since all attempts to ask IT to do it have failed. The problem is, since Oracle Forms are Java based there are no "controls" as there would be on say a windows application or an HTML based form. Does anyone know of a way to tell the PC to (example only) click edit field 3 on the RMA creation form and then enter the data? The only way I can programmatically navigate Oracle is with hotkeys and it's very unreliable. I'm not concerned about the language or learning a new application to resolve this issue. I currently know (elementary to Intermediate levels) Java, VB.NET and will be taking C++ in school. Is there a tool, bridge, element spy of some sort that will allow me to send commands to elements on the forms? edit APC sez: Oracle Forms over the web run as a Java applet. I mention this because it may be relevant to your responses.

  • MySQL MyISAM table performance... painfully, painfully slow

    - by Salman A
    I've got a table structure that can be summarized as follows: pagegroup * pagegroupid * name has 3600 rows page * pageid * pagegroupid * data references pagegroup; has 10000 rows; can have anything between 1-700 rows per pagegroup; the data column is of type mediumtext and the column contains 100k - 200kbytes data per row userdata * userdataid * pageid * column1 * column2 * column9 references page; has about 300,000 rows; can have about 1-50 rows per page The above structure is pretty straight forwad, the problem is that that a join from userdata to page group is terribly, terribly slow even though I have indexed all columns that should be indexed. The time needed to run a query for such a join (userdata inner_join page inner_join pagegroup) exceeds 3 minutes. This is terribly slow considering the fact that I am not selecting the data column at all. Example of the query that takes too long: SELECT userdata.column1, pagegroup.name FROM userdata INNER JOIN page USING( pageid ) INNER JOIN pagegroup USING( pagegroupid ) Please help by explaining why does it take so long and what can i do to make it faster. Edit #1 Explain returns following gibberish: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE userdata ALL pageid 372420 1 SIMPLE page eq_ref PRIMARY,pagegroupid PRIMARY 4 topsecret.userdata.pageid 1 1 SIMPLE pagegroup eq_ref PRIMARY PRIMARY 4 topsecret.page.pagegroupid 1 Edit #2 SELECT u.field2, p.pageid FROM userdata u INNER JOIN page p ON u.pageid = p.pageid; /* 0.07 sec execution, 6.05 sec fecth */ id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE u ALL pageid 372420 1 SIMPLE p eq_ref PRIMARY PRIMARY 4 topsecret.u.pageid 1 Using index SELECT p.pageid, g.pagegroupid FROM page p INNER JOIN pagegroup g ON p.pagegroupid = g.pagegroupid; /* 9.37 sec execution, 60.0 sec fetch */ id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE g index PRIMARY PRIMARY 4 3646 Using index 1 SIMPLE p ref pagegroupid pagegroupid 5 topsecret.g.pagegroupid 3 Using where Moral of the story Keep medium/long text columns in a separate table if you run into performance problems such as this one.

  • computing hash values, integral types versus struct/class

    - by aaa
    hello I would like to know if there is a difference in speed between computing hash value (for example std::map key) of primitive integral type, such as int64_t and pod type, for example struct { int16_t v[4]; };. I know this is going to implementation specific, so my question ultimately pertains to gnu standard library. Thanks

  • Where are Riak Post-Commit Hooks run?

    - by pixelcort
    I'm trying to evaluate using Riak's Post-Commit Hooks to build a distributed, incremental MapReduce-based index, but was wondering which Riak nodes the Post-Commit Hooks actually run on. Are they run on the nodes the client used to put the commits, or on the primary nodes where the data is persisted? If it's the latter, I'm thinking I can from there efficiently do a map or reduce and put additional records from the output.

  • Using Factory to get Injected objects

    - by ryudice
    Is it good practice to have a Factory method to retrieve injected objects or is it OK to just use the factory method from the DI framework? I'm using structure map, should I just use ObjectFactory.GetInstance();, or should I create factory class and inside this class call ObjectFactory.GetInstance();? because if I call ObjectFactory.GetInstance(); in my classes I would be creating coupling to the DI framework? sorry if I'm being ignorant, I'm new to this concepts. Thanks!

  • Compile and optimize for different target architectures

    - by Peter Smit
    Summary: I want to take advantage of compiler optimizations and processor instruction sets, but still have a portable application (running on different processors). Normally I could indeed compile 5 times and let the user choose the right one to run. My question is: how can I can automate this, so that the processor is detected at runtime and the right executable is executed without the user having to chose it? I have an application with a lot of low level math calculations. These calculations will typically run for a long time. I would like to take advantage of as much optimization as possible, preferably also of (not always supported) instruction sets. On the other hand I would like my application to be portable and easy to use (so I would not like to compile 5 different versions and let the user choose). Is there a possibility to compile 5 different versions of my code and run dynamically the most optimized version that's possible at execution time? With 5 different versions I mean with different instruction sets and different optimizations for processors. I don't care about the size of the application. At this moment I'm using gcc on Linux (my code is in C++), but I'm also interested in this for the Intel compiler and for the MinGW compiler for compilation to Windows. The executable doesn't have to be able to run on different OS'es, but ideally there would be something possible with automatically selecting 32 bit and 64 bit as well. Edit: Please give clear pointers how to do it, preferably with small code examples or links to explanations. From my point of view I need a super generic solution, which is applicable on any random C++ project I have later. Edit I assigned the bounty to ShuggyCoUk, he had a great number of pointers to look out for. I would have liked to split it between multiple answers but that is not possible. I'm not having this implemented yet, so the question is still 'open'! Please, still add and/or improve answers, even though there is no bounty to be given anymore. Thanks everybody!

  • How reliable is Verify() in Moq?

    - by matthewayinde
    I'm only new to Unit Testing and ASP.NET MVC. I've been trying to get my head into both using Steve Sanderson's "Pro ASP.NET MVC Framework". In the book there is this piece of code: public class AdminController : Controller { ... [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Product product, HttpPostedFileBase image) { ... productsRepository.SaveProduct(product); TempData["message"] = product.Name + " has been saved."; return RedirectToAction("Index"); } } That he tests like so: [Test] public void Edit_Action_Saves_Product_To_Repository_And_Redirects_To_Index() { // Arrange AdminController controller = new AdminController(mockRepos.Object); Product newProduct = new Product(); // Act var result = (RedirectToRouteResult)controller.Edit(newProduct, null); // Assert: Saved product to repository and redirected mockRepos.Verify(x => x.SaveProduct(newProduct)); Assert.AreEqual("Index", result.RouteValues["action"]); } THE TEST PASSES. So I intensionally corrupt the code by adding "productsRepository.DeleteProduct(product);" after the "SaveProduct(product);" as in: ... productsRepository.SaveProduct(product); productsRepository.DeleteProduct(product); ... THE TEST PASSES.(i.e Condones a calamitous [hypnosis + intellisense]-induced typo :) ) Could this test be written better? Or is there something I should know? Thanks a lot.

  • Editing a User's Likes on Facebook

    - by Ed Marty
    I've been looking at the Facebook API to find some way to edit a user's Likes (that is, add or remove items from https://graph.facebook.com/me/likes/). The API doesn't say anything about it specifically, but does say this: You can publish to the Facebook graph by issuing HTTP POST requests to the appropriate connection URLs above. Where above, one of the connection URLs is the aforementioned https://graph.facebook.com/me/likes link. However, there's no documentation for the PROFILE_ID/likes post, and whenever I try to post it returns the error "invalid post_id". I assume this is because to like something, you post a request to POST_ID/likes. It's a bit inconsistent. What I'm trying to do is get the user's profile to add a Page to their likes (by posting using the page's id as an "id" parameter in the post body). However, it seems like there's just no way to edit user's likes. At the end of the day, I just want to allow a user to click a button in my application (mobile device application, not a web app) and have them add our Facebook page into their list of pages, and I've found no way of doing that short of presenting our page to them and making them click on the "Like" button manually. Many other things are supported without showing the Facebook website, like posting to their wall or making albums, but I can't find anything to do this. Any ideas?

  • Perform Grouping of Resultsets in Code, not on Database Level

    - by NinjaBomb
    Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it? EDIT I have attempted to group the result in SQL using the exact same grouping query suggested by Thomas Levesque and both times our entire RDBMS crashed trying to process the query. I was under the impression that Linq was not available until .NET 3.5. This is a .NET 2.0 web application so I did not think it was an option. Am I wrong in thinking that? EDIT Starting a bounty because I believe this would be a good technique to have in the toolbox to use no matter where the different resultsets are coming from. I believe knowing the most concise way to group any 2 somewhat similar sets of data in code (without .NET LINQ) would be beneficial to more people than just me.

  • XCode: Delete line hot-key

    I'm looking for a way to map some hot-keys to "delete the line that my cursor is on" in Xcode. I found "delete to end of line" and "delete to beginning of line" in the text key bindings, but I am missing how to completely delete the line no matter what I have selected. TextMate has this functionality mapped to Ctrl+Shift+D and I'd like the same thing if possible. Any ideas?

  • Drupal workflow action access integrated with taxonomy access control?

    - by groovehunter
    hi, I am building a DMS for our intranet and use a taxonomy hierarchy because we need access control that way. All company locations manage (upload,edit) their own documents but should be able to access all. This is inherited to the child terms and works fine. Additionally we want simple 3-step workflow (draft,published,archived). So i introduced roles for editor, publisher and docadmin and set permissions for the transitions. Also triggers to effectivly (un)publish documents. But (of course) a user of role publisher can do the transition for ALL documents. But we want publisher for each company location (top taxonomy level, see above). Could this be achieved? Do i have to set it up by myself (i guess "rules" is appropriate to do this) or is there another module helping. role inheritance was a guess, but that is only about roles (naturally). "module grants" i use and checked first option. That way my thoughts are going. I hope you get my idea resp. problem. drupal 6.16 current edit: I reread the docs and found ie. http://drupal.org/node/408018 Revisioning for categorized content. Will reread that.

  • asp.net mvc url routing
