  • Dynamic Data: how to filter dropdown for foreign key on edit page

    - by Leonv
    I have Organisation with a foreign key to a Manager. Managers can be active, or inactive. On the Dynamic Data edit page for Organisation, I need to filter the dropdown for Manager to only show active records. I started out by making a custom version of DynamicData\FieldTemplates\ForeignKey_Edit.ascx and setting a UIHint to the new field template on Organisation.Manager. But, how to customize the linq or sql query that runs to load the Managers? Using Linq-to-SQL and DynamicDataFutures

  • What is array portability?

    - by bobo
    From this page: http://www.doctrine-project.org/documentation/manual/1_2/en/working-with-models#dealing-with-relations:creating-related-records You can see that it says $obj['property']; is the recommended way of referring to an object's property in Doctrine for array portability purposes. I never heard about this term before and google did not come up with useful result. What is that?

  • Fulltext search for django : Mysql not so bad ? (vs sphinx, xapian)

    - by Eric
    I am studying fulltext search engines for django. It must be simple to install, fast indexing, fast index update, not blocking while indexing, fast search. After reading many web pages, I put in short list : Mysql MYISAM fulltext, djapian/python-xapian, and django-sphinx I did not choose lucene because it seems complex, nor haystack as it has less features than djapian/django-sphinx (like fields weighting). Then I made some benchmarks, to do so, I collected many free books on the net to generate a database table with 1 485 000 records (id,title,body), each record is about 600 bytes long. From the database, I also generated a list of 100 000 existing words and shuffled them to create a search list. For the tests, I made 2 runs on my laptop (4Go RAM, Dual core 2.0Ghz): the first one, just after a server reboot to clear all caches, the second is done juste after in order to test how good are cached results. Here are the "home made" benchmark results : 1485000 records with Title (150 bytes) and body (450 bytes) Mysql 5.0.75/Ubuntu 9.04 Fulltext : ========================================================================== Full indexing : 7m14.146s 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:11.553524 next run : 0:00:00.168508 Mysql 5.5.4 m3/Ubuntu 9.04 Fulltext : ========================================================================== Full indexing : 6m08.154s 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:11.553524 next run : 0:00:00.168508 1 thread, 100000 searchs with single word randomly taken from database : First run : 9m09s next run : 5m38s 1 thread, 10000 random strings (random strings should not be found in database) : just after the 100000 search test : 0:00:15.007353 1 thread, boolean search : 1000 x (+word1 +word2) First run : 0:00:21.205404 next run : 0:00:00.145098 Djapian Fulltext : ========================================================================== Full indexing : 84m7.601s 1 thread, 1000 searchs with single word randomly taken from database with prefetch : First run : 0:02:28.085680 next run : 0:00:14.300236 python-xapian Fulltext : ========================================================================== 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:26.402084 next run : 0:00:00.695092 django-sphinx Fulltext : ========================================================================== Full indexing : 1m25.957s 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:30.073001 next run : 0:00:05.203294 1 thread, 100000 searchs with single word randomly taken from database : First run : 12m48s next run : 9m45s 1 thread, 10000 random strings (random strings should not be found in database) : just after the 100000 search test : 0:00:23.535319 1 thread, boolean search : 1000 x (word1 word2) First run : 0:00:20.856486 next run : 0:00:03.005416 As you can see, Mysql is not so bad at all for fulltext search. In addition, its query cache is very efficient. Mysql seems to me a good choice as there is nothing to install (I need just to write a small script to synchronize an Innodb production table to a MyISAM search table) and as I do not really need advanced search feature like stemming etc... Here is the question : What do you think about Mysql fulltext search engine vs sphinx and xapian ?

  • speed: XmlTextReader vs LinqtoXml

    - by Michel
    Hi, i'm about to read some xml (who isn't :-)) This time however it's a lot of data: about 30.000 records with 5 properties, all in one file. Till now i've always read that the XmlTextReader is the fastest way to read xml data, but now there also is the (nice sytax of) linqtoXml. Does anybody know any performance issues, or that there aren't any, with LinqToXml? Michel

    How in SQL could you "zip" together records in separate tables (à la the UNIX paste(1) utility)? For example, assuming two tables, A and B, like so: A B ======== ==== Harkness unu Costello du Sato tri Harper Jones How could you produce a single result set NAME | NUM =============== Harkness | unu Costello | du Sato | tri Harper | NULL Jones | NULL ?

  • Parallel port recording to file on Win XP

    - by Nikola Kotur
    Hi there. I need to write a simple program that records all the input from parallel port into a file. Data flows from industrial machine, setup is fairly simple, but I can't find any good open source examples on parallel port reading for Windows. Do you know a software that does this (and lets me learn how to do it myself), or is there any guideline for parallel port programming on XP? Thanks.

  • VBA/SQL recordsets

    - by intruesiive
    The project I'm asking about is for sending an email to teachers asking what books they're using for the classes they're teaching next semester, so that the books can be ordered. I have a query that compares the course number of this upcoming semester's classes to the course numbers of historical textbook orders, pulling out only those classes that are being taught this semester. That's where I get lost. I have a table that contains the following: -Professor -Course Number -Year -Book -Title The data looks like this: professor year course number title smith 13 1111 Pride and Prejudice smith 13 1111 The Fountainhead smith 13 1222 The Alchemist smith 12 1111 Pride and Prejudice smith 11 1222 Infinite Jest smith 10 1333 The Bible smith 13 1333 The Bible smith 12 1222 The Alchemist smith 10 1111 Moby Dick johnson 12 1222 The Tipping Point johnson 11 1333 Anna Kerenina johnson 10 1333 Everything is Illuminated johnson 12 1222 The Savage Detectives johnson 11 1333 In Search of Lost Time johnson 10 1333 Great Expectations johnson 9 1222 Proust on the Shore Here's what I need the code to do "on paper": Group the records by professor. Determine every unique course number in that group, and group records by course number. For each unique course number, determine the highest year associated. Then spit out every record with that professor+course number+year combination. With the sample data, the results would be: professor year course number title smith 13 1111 Pride and Prejudice smith 13 1111 The Fountainhead smith 13 1222 The Alchemist smith 13 1333 The Bible johnson 12 1222 The Tipping Point johnson 11 1333 Anna Kerenina johnson 12 1222 The Savage Detectives johnson 11 1333 In Search of Lost Time I'm thinking I should make a record set for each teacher, and within that, another record set for each course number. Within the course number record set, I need the system to determine what the highest year number is - maybe store that in a variable? Then pull out every associated record so that if the teacher ordered 3 books the last time they taught that class (whether it was in 2013 or 2012 and so on) all three books display. I'm not sure I'm thinking of record sets in the right way, though. My SQL so far is basic and clearly doesn't work: SELECT [All].Professor, [All].Course, Max([All].Year) FROM [All] GROUP BY [All].Professor, [All].Course; Thanks for your help.

  • Mysql password hashing method old vs new

    - by The Disintegrator
    I'm trying to connect to a mysql server at dreamhost from a php scrip located in a server at slicehost (two different hosting companies). I need to do this so I can transfer new data at slicehost to dreamhost. Using a dump is not an option because the table structures are different and i only need to transfer a small subset of data (100-200 daily records) The problem is that I'm using the new MySQL Password Hashing method at slicehost, and dreamhost uses the old one, So i get $link = mysql_connect($mysqlHost, $mysqlUser, $mysqlPass, FALSE); Warning: mysql_connect() [function.mysql-connect]: OK packet 6 bytes shorter than expected Warning: mysql_connect() [function.mysql-connect]: mysqlnd cannot connect to MySQL 4.1+ using old authentication Warning: mysql_query() [function.mysql-query]: Access denied for user 'nodari'@'localhost' (using password: NO) facts: I need to continue using the new method at slicehost and i can't use an older php version/library The database is too big to transfer it every day with a dump Even if i did this, the tables have different structures I need to copy only a small subset of it, in a daily basis (only the changes of the day, 100-200 records) Since the tables are so different, i need to use php as a bridge to normalize the data Already googled it Already talked to both support stafs The more obvious option to me would be to start using the new MySQL Password Hashing method at dreamhost, but they will not change it and i'm not root so i can't do this myself. Any wild idea? By VolkerK sugestion: mysql> SET SESSION old_passwords=0; Query OK, 0 rows affected (0.01 sec) mysql> SELECT @@global.old_passwords,@@session.old_passwords, Length(PASSWORD('abc')); +------------------------+-------------------------+-------------------------+ | @@global.old_passwords | @@session.old_passwords | Length(PASSWORD('abc')) | +------------------------+-------------------------+-------------------------+ | 1 | 0 | 41 | +------------------------+-------------------------+-------------------------+ 1 row in set (0.00 sec) The obvious thing now would be run a mysql SET GLOBAL old_passwords=0; But i need SUPER privilege to do that and they wont give it to me if I run the query SET PASSWORD FOR 'nodari'@'HOSTNAME' = PASSWORD('new password'); I get the error ERROR 1044 (42000): Access denied for user 'nodari'@'67.205.0.0/255.255.192.0' to database 'mysql' I'm not root... The guy at dreamhost support insist saying thet the problem is at my end. But he said he will run any query I tell him since it's a private server. So, I need to tell this guy EXACTLY what to run. So, telling him to run SET SESSION old_passwords=0; SET GLOBAL old_passwords=0; SET PASSWORD FOR 'nodari'@'HOSTNAME' = PASSWORD('new password'); grant all privileges on *.* to nodari@HOSTNAME identified by 'new password'; would be a good start?

  • Ruby on Rails 2.3.5: update_all failing on ActiveRecord

    - by randombits
    I'm trying to update a collection of records in my database using ActiveRecord's update_all. Enter script/console. MyModel.update_all("reserved = 1", :limit => 1000) ActiveRecord thinks limit is a column, says it's unknown and throws an exception. According to the documentation though, my syntax looks sane. This is RoR 2.3.5. When doing MyModel.update_all("reserved = 1") alone, it works just fine.

Here is the documentation http://www.doctrine-project.org/documentation/manual/1_2/en/working-with-models#dealing-with-relations:retrieving-related-records My code is $User = Doctrine_Core::getTable("User")->find(1); when I access relations by $User-Phonenumbers, it works. When I convert User object to array by using toArray() method, it does not convert relations to array. It simply display $User data. Am i missing something?
