  • Kohana 2.3.4 ORM pivot table query

    - by anthony
    I'm trying to query a pivot table with Kohana's ORM and I'm wondering if there is a built in function I'm missing. Currently I only have 2 models setup for the tables "categories" and "products". There is a pivot table "categories_products", but I don't need a model for it when inserting data with this: $product = ORM::factory('product'); $product->add(ORM::factory('category', $addCat)); However, I can't figure out how to query it without creating a model for it. The "join_table" function only returns the name of the pivot table (which I thought selected the table at first). If you can save data to the pivot table without a model, it seems to me that you should be able to retrieve data in a similar way. Any ideas?

  • Properly handling unicode characters in Rails

    - by Gdeglin
    By default Rails allows users of our application to input non-utf8 data, such as: ¶®«¼ However when we attempt to retrieve the data from our database and render it in a template Rails incorrectly assumes that it is in UTF-8 format and throws an error. ArgumentError: invalid byte sequence in UTF-8 What is the best way to handle this? I have seen one fix that suggested sanitizing the data in every place the user can input it. However, that would involve changing a considerable amount of code and it would strip out the characters entirely. Ideally we would want some characters converted to their UTF-8 equivalents. Our environment: Ruby: 1.9.1 Rails 2.3.5 MySql Gem: 2.8.1 This is a serious and urgent problem for us so your answers are very appreciated!

  • How to configure SQLite db in Visual Studio

    - by ChrisC
    I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

  • Postgresql - one database for everyone, or one-database per customer

    - by user337876
    I'm working on a web-based business application where each customer will need to have their own data (think basecamphq.com type model) For scalability and ease-of-upgrades, I'd prefer to have a single database where each customer gets a filtered version of the data. The problem is how to guarantee that they stay sandboxed to their own data. Trying to enforce it in code seems like a disaster waiting to happen. I know Oracle has a way to append a where clause to every query based on a login id, but does Postgresql have anything similar? If not, is there a different design pattern I could use (like creating a view of each table for each customer that filters)? Worse case scenario, what is the performance/memory overhead of having 1000 100M databases vs having a single 1Tb database? I will need to provide backup/restore functionality on a per-customer basis which is dead-simple on a single database but quite a bit trickier if they are sharing the database with other customers.

  • Large number array compression

    - by gatapia
    Hi All, I've got a javascript application that sends a large amount of numerical data down the wire. This data is then stored in a database. I am having size issues (too much bandwidth, database getting too big). I am now ready to sacrifice some performance for compression. I was thinking of implementing a base 62 number.toString(62) and parseInt(compressed, 62). This would certainly reduce the size of the data but before I go ahead and do this I thought I would put it to the folks here as I know there must be some outside the box solution I have not considered. The basic specs are: - Compress large number arrays into strings for JSONP transfer (So I think UTF is out) - Be relatively fast, look I'm not expecting same performance as I have now but I also don't want gzip compression either. Any ideas would be greatly appreciated. Thanks Guido Tapia

  • How to strink matrix using array mask in Matlab?

    - by Pyrolistical
    This seems to be a very common problem of mine. data = [1 2 3; 4 5 6]; mask = [true false true]; mask = repmat(mask, 2, 1); data(mask) ==> [1; 4; 3; 6] What I wanted was [1 3; 4 6] Yes I can just reshape it to the right size, but that seems the wrong way to do it. Is there a better way? Why doesn't data(mask) return a matrix when it is actually rectangular? I understand in the general case it may not be, but in my case since my original mask is an array it always will be.

Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

  • Change color on single-series line chart using rCharts and Highcharts?

    - by Sharon
    Is it possible to change the color of a line using rCharts and Highcharts so that the line color changes depending on a factor? I've done this with ggplot2 but would like to make an interactive version if possible. I've tried h1 <- Highcharts$new() h1$chart(type="line") h1$series(data=mydf$myvalue, name="", groups = c("myfactor")) h1$xAxis(tickInterval = 4, categories = mydf$myXaxis) but that's not working, line stays the same color. Sample data myvalue <- c(16, 18, 5, 14, 10) myXaxis <- c(1,2,3,4,5) myfactor <- c("old", "old", "old", "new", "new") mydf <- data.frame(myvalue, myXaxis, myfactor) Thanks for any suggestions.

  • echoing javascript when an ajax funtion is called

  • Changing error message for datatype validation?

    - by Matthias
    Hey guys, I've a small question on ASP.NET MVC 2. I'm using Data Annotations on my Presentation Model and its model binder per default. But one step back, I want to do the most elementary thing: validation of the data type. Let's say I have an "int ID" on my model and want to edit the according entity in my view. If I enter something wrong like "foo", then I get a model error back, but the validation message is on English. I want to have this message in other languages, too. How can I do this? I remember that in MVC 1 I've written a custom model binder which checks the data types, but that's not what I want to do (at least not in MVC 2). Thus I hope there is a better way... Thanks, Matthias

  • Accessing Active Directory Role Membership through LDAP using SQL Server 2005

    I would like to get a list of Active Directory users along with the security groups they are members of using SQL Server 2005 linked servers.

  • Reading multiple files with PHPExcel

    - by KaOSoFt
    Hello there. I just recently started using this library (the one from CodePlex), but I ran into some issues. My goal is to use it so I can process some data from multiple Excel files, and send such data to a database, per file. I'm doing something like: foreach( $file_list as $file ) { $book = PHPExcel_IOFactory::load( $path . $file ); } So, inside the foreach I'm (for now) just showing the data to the user, but after five files, I get a memory error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 50688 bytes) in /var/www/test/classes/PHPExcel/Shared/OLERead.php on line 76 Is there a way to __destruct the object after each file is loaded, so space is reserved (made free) for the next file, instead of accumulating it, or do you rather know of a reason and work-around for this? Please let me know any suggestions you have. Thanks in advance.

  • getjson jquery parsing an array

    - by Ozaki
    TLDR: Want to get each heading from an array and insert it into a div without knowing what is inside the div using Jquery - getJSON. I have JSON array lets say: jsonfeed({ "items": [ { "d":{"title":"034324324-22344231-10"} }, { "d"{"title":"23423404-3423422-10"} }, { "d"{"title":"0234234324-32432422-10"} }, { "d"{"title":"0234234324-223534534-10"} ] }) And I want to parse it as for each "title" to insert it into a div. Trying along the lines of $.getJSON(url, function(data){ $.each(data.items, function(i,item){ $('#testfield').html('<p>' + item.d.title + '</p>'); }); }); to no avail. I am using Getjson in other places but in cases where I know what request I am making. e.g: $('#livetime').html(data.Time); Which is all working perfectly fine but in this case I need to get the details out of the array without knowing what is inside the array I'm sure there is something simple that I'm missing here or doing wrong ^^.

  • LLBLGen: Copy table from one database to another

And if destination table already contains some data, then rows from source table should not override, but be added to the destination table. In our project we use LLBLGen and LINQ to LLBLGen to as ORM solution. Example: Table 1: Table 2: Table 1: Key Value Key Value Key Value 1 One 1 T2_One Result=> 1 One 2 Two 2 T2_Two 2 Two 3 Three 3 Three 4 T2_One 5 T2_Two

  • .NET: will Random.Random operate differently inside a static method

    - by Craig Johnston
    I am having difficulty with the following code which is inside a static method of a non-static class. int iRand; int rand; rand = new Random((int)DateTime.Now.Ticks); iRand = rand.Next(50000); The iRand number, along with some other values, are being inserted into a new row of an Access MDB table via OLEDB. The iRand number is being inserted into a field that is part of the primary key, and the insert attempt is throwing the following exception even though the iRand number is supposed to be random: System.Data.OleDb.OleDbException: The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again. Could the fact the method is static be making the iRand number stay the same, for some reason?

  • SQLite - a smart way to remove and add new objects

    - by Ilya
    Hi, I have a table in my database and I want for each row in my table to have an unique id and to have the rows named sequently. For example: I have 10 rows, each has an id - starting from 0, ending at 9. When I remove a row from a table, lets say - row number 5, there occurs a "hole". And afterwards I add more data, but the "hole" is still there. It is important for me to know exact number of rows and to have at every row data in order to access my table arbitrarily. There is a way in sqlite to do it? Or do I have to manually manage removing and adding of data? Thank you in advance, Ilya.
