• Why do I have a page hit for 404.php after each legitimate pagehit?

  - by Nathan Long

  I'm working with an intranet system that, on each page, checks the user's cookie, verifies that they can see the current page based on database permissions, and records a page hit that includes their id and the page URL. I just noticed that in the pagehits table, I see an entry for 404.php (my custom 404 page specified in the Apache config) one second after each legitimate page hit. Is this probably my fault, or does it have something to do with how Apache decides to load the 404 page? I'm using Apache 2.2.14 (Win32) and PHP 5.3.2.

• CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

  - by Jason McCreary

  I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

• Obtain patterns in one file from another using ack or awk or better way than grep?

  - by Rock

  Is there a way to obtain patterns in one file (a list of patterns) from another file using ack as the -f option in grep? I see there is an -f option in ack but it's different with the -f in grep. Perhaps an example will give you a better idea. Suppose I have file1: file1: a c e And file2: file2: a 1 b 2 c 3 d 4 e 5 And I want to obtain all the patterns in file1 from file2 to give: a 1 c 3 e 5 Can ack do this? Otherwise, is there a better way to handle the job (such like awk or using hash) because I have millions of records in both files and really need an efficient way to complete? Thanks!

• efficiently trimming postgresql tables

  - by agilefall

  I have about 10 tables with over 2 million records and one with 30 million. I would like to efficiently remove older data from each of these tables. My general algorithm is: create a temp table for each large table and populate it with newer data truncate the original tables copy tmp data back to original tables using: "insert into originaltable (select * from tmp_table)" However, the last step of copying the data back is taking longer than I'd like. I thought about deleting the original tables and making the temp tables "permanent", but I lose constraint/foreign key info. If I delete from the tables directly, it takes much longer. Given that I need to preserve all foreign keys and constraints, are there any faster ways of removing the older data? Thanks.

• Problem with altering model attributes in controller

  - by SpawnCxy

  Hi all, Today I've got a problem when I tried using following code to alter the model attribute in the controller function userlist($trigger = 1) { if($trigger == 1) { $this->User->useTable = 'betausers'; //'betausers' is completely the same structure as table 'users' } $users = $this->User->find('all'); debug($users); } And the model file is class User extends AppModel { var $name = "User"; //var $useTable = 'betausers'; function beforeFind() //only for debug { debug($this->useTable); } } The debug message in the model showed the userTable attribute had been changed to betausers.And It was supposed to show all records in table betausers.However,I still got the data in the users,which quite confused me.And I hope someone can show me some directions to solve this problem. Regards

• Using fixtures with factory_girl

  - by deb

  When building the following factory: Factory.define :user do |f| f.sequence(:name) { |n| "foo#{n}" } f.resume_type_id { ResumeType.first.id } end ResumeType.first returns nil and I get an error. ResumeType records are loaded via fixtures. I checked using the console and the entries are there, the table is not empty. I've found a similar example in the factory_girl mailing list, and it's supposed to work. What am I missing? Do I have to somehow tell factory_girl to set up the fixtures before running the tests?

• choose append to existing backup instead of overwrite

  - by aron

  Hello, I have a database and I made it's first backup 2 days ago. Then yesterday I spent an entire adding new records. This morning I ran a backup, (but I selected append to existing backup set) as pictured below. I just ran a restore and I found that it wiped out all my data from yesterday and it restored it from the backup of 2 days ago. Not the version from this mornings backup. I zipped this backup file to be safe. I changed some data in the DB, Then I ran the back up again, but this time I selected "overwrite all existing backup sets" Now when I restore the db it's seems to restore the data from the backup correctly. I think I learned a lesson here, correctly if I'm wrong My questions is, Did I lose an entire day of work? I still have this morning's backup .bak file safe in a zip. Is there anyway I can restore is with the right data?

• Insert error when sending post array to activerecord

  - by Gonzalo

  I am using CodeIgniter + phpActiveRecord. I am getting all the records from the $_POST array and I want to send that same array to my activeRecord class to insert the data into the DB. This line doesn't seem to be working but I can't get the error because the page is just blank: Car::create($this->input->post()); If the names of the fields are equal to the names of the columns in the table, should it what I pasted above work? ==========SOLVED======== It is possible to do it, and in the model of the object one can add var $name_of_the_field_which_you_don't_process = FALSE; And that's it.

• Django. default=datetime.now() problem

  - by Shamanu4

  Hello. I've such db model: from datetime import datetime class TermPayment(models.Model): dev_session = models.ForeignKey(DeviceSession, related_name='payments') user_session = models.ForeignKey(UserSession, related_name='payment') date = models.DateTimeField(default=datetime.now(),blank=True) sum = models.FloatField(default=0) cnt = models.IntegerField(default=0) class Meta: db_table = 'term_payments' ordering = ['-date'] and here new instance is added: # ... tp = TermPayment() tp.dev_session = self.conn.session # device session hash tp.user_session = self.session # user session hash tp.sum = sum tp.cnt = cnt tp.save() But i've a problem: all records in database have the same value in date field - the date of the first payment.

• T-SQL Getting duplicate rows returned

  - by cBlaine

  The following code section is returning multiple columns for a few records. SELECT a.ClientID,ltrim(rtrim(c.FirstName)) + ' ' + case when c.MiddleName <> '' then ltrim(rtrim(c.MiddleName)) + '. ' else '' end + ltrim(rtrim(c.LastName)) as ClientName, a.MISCode, b.Address, b.City, dbo.ClientGetEnrolledPrograms(CONVERT(int,a.ClientID)) as Abbreviation FROM ClientDetail a JOIN Address b on(a.PersonID = b.PersonID) JOIN Person c on(a.PersonID = c.PersonID) LEFT JOIN ProgramEnrollments d on(d.ClientID = a.ClientID and d.Status = 'Enrolled' and d.HistoricalPKID is null) LEFT JOIN Program e on(d.ProgramID = e.ProgramID and e.HistoricalPKID is null) WHERE a.MichiganWorksData=1 I've isolated the issue to the ProgramEnrollments table. This table holds one-to-many relationships where each ClientID can be enrolled in many programs. So for each program a client is enrolled in, there is a record in the table. The final result set is therefore returning a row for each row in the ProgramEnrollments table based on these joins. I presume my join is the issue but I don't see the problem. Thoughts/Suggestions? Thanks, Chuck

• ASP.NET: How to assign ID to a field in DetailsView?

  - by jawonlee

  I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time. I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do? Thank you in advance.

• update each recordset with datareader

  hi, my situation is the following: i have a datareader and loop over all records returned by a select statement and then call a function with a value from that row. but now i need to update a column in each row, after the function has been called. using a separate update statement seems like a huge overkill. what's the best method to do so? i've heard about dataadapters and datasets—but the only thing i know is that they exist, not how to use them (properly) in this case. platform is c# with sql server

• SQL query to select distinct record with 2 or more repetition in another field

  - by kyohiros

  So I have this table of book orders, it contains 2 columns, one is the order ID(primary key) and another is the ID of the book that the customer ordered. For example: | OrderID | BookID | | 0001 | B002 | | 0002 | B005 | | 0003 | B002 | | 0004 | B003 | | 0005 | B005 | | 0006 | B002 | | 0007 | B002 | What I want is to get the IDs of the books that got 2 or more purchases/orders, for example if I run the SQL query against the above data, I would get this as the result: | BookID | | B002 | | B005 | I don't know if this can be archived in SQL or I have to built a simpler statement and repetitive run the query against all the records in another language. I need some help and thanks for reading my question.

• Returning multiple datasets from a stored proc in VB

  - by Ryan Stephens

  I have an encrypted SQL Server stored proc that I run with (or the vb .net equivalent code of): declare @p4 nvarchar(100) set @p4=NULL declare @p5 bigint set @p5=NULL exec AA_PAY_BACS_EXPORT_RETRIEVE_S @PS_UserId=N'ADMN', @PS_Department=N'', @PS_PayFrequency=2, @PS_ErrorDescription=@p4 output select @p4, @p5 this returns 2 datasets and the output parameters for the results, the datasets are made up of various table joins etc, one holds the header record and one the detail records. I need to get the 2 datasets into a structure in VB .net (e.g. linq, sqldatareader, typed datasets) so that I can code with them, I don't know what tables any of this comes from and there are alot of them Whooopeee!!! I came close using Linq to SQL and IMultipleResults but got frustrated when I had to recode it every time I made a change to the designer file. My feelings are that there must be a simple way to do this, any ideas?

• How to have partial incremental synchronizations based on a GUID?

  - by Gonçalo Veiga

  I need to synchronize an SQL Server database to Oracle through an Oracle Transparent Gateway. The synchronization is performed in batches, so I need to get the next set of data from the point where I left off. The problem I'm having is that the only field I have in the source, to help me, is a GUID. If it were a number I could just order by it, keep the last one processed and restart the process by getting the records which are my recorded number. This won't work with a GUID. Any ideas?

• How to limit SMTP delivery to hourly batches

  - by Jeremy W

  In an effort to keep us from being labeled spammers by major ISPs (in addition to SPF records, privacy policies, CANSPAM compliance and the like) - I wanted to limit the amount of mail we send out an hour. Is this possible in W2K3 SMTP server? I was looking at outbound connection properties in the SMTP virtual server config screens...It's just not that clear if tinkering with those settings are going to do what I want. In a nutshell, I'd love mail being sent by this server to queue up and send for example, 5,000 messages every 10 minutes or so. Is this possible?

• Perl: Fastest way to get directory (and subdirs) size on unix - using stat() at the moment

  - by ivicas

  I am using Perl stat() function to get the size of directory and it's subdirectories. I have a list of about 20 parent directories which have few thousand recursive subdirs and every subdir has few hundred records. Main computing part of script looks like this: sub getDirSize { my $dirSize = 0; my @dirContent = <*>; my $sizeOfFilesInDir = 0; foreach my $dirContent (@dirContent) { if (-f $dirContent) { my $size = (stat($dirContent))[7]; $dirSize += $size; } elsif (-d $dirContent) { $dirSize += getDirSize($dirContent); } } return $dirSize; } The script is executing for more than one hour and I want to make it faster. I was trying with the shell du command, but the output of du (transfered to bytes) is not accurate. And it is also quite time consuming. I am working on HP-UNIX 11i v1.

• In what circumstances can large pages produce a speedup ?

  - by timday

  Modern x86 CPUs have the ability to support larger page sizes than the legacy 4K (ie 2MB or 4MB), and there are OS facilities (Linux, Windows) to access this functionality. The Microsoft link above states large pages "increase the efficiency of the translation buffer, which can increase performance for frequently accessed memory". Which isn't very helpful in predicting whether large pages will improve any given situation. I'm interested in concrete, preferably quantified, examples of where moving some program logic (or a whole application) to use huge pages has resulted in some performance improvement. Anyone got any success stories ? There's one particular case I know of myself: using huge pages can dramatically reduce the time needed to fork a large process (presumably as the number of TLB records needing copying is reduced by a factor on the order of 1000). I'm interested in whether huge pages can also benefit more mundane applications though.

• how to convert numbers to alpha numeric system with php

  - by Patrick

  Im not sure what this is called, which is why im having trouble searching for it. What im looking to do, is take numbers, and convert them to some alpha numeric base so that the number say 5000, wouldnt read 5000, but like G4u or something like that. The idea being to save space and also not make it obvious how many records there are in a given system. Im using php, so if there is something like this built into php even better, but even a name for this method would be helpful at this point Again, sorry for not being able to be more clear, im just not sure what this is called.

• Treeview Slow in IE?!?!

  - by Mike

  I have a treeview with around 200 records that needs to be fully expanded at all times (so no loading on demand). It is inside of an update panel with the updatemode set to conditional. There are other update panels on the page as well that are set to conditional. Depending on user actions the tree may need to be rebuilt by calling databind and updating the updatepanel. Everything works fine in firefox, longest postback about 2 seconds. With IE I have to wait up to 30 seconds sometimes and the action may have nothing to do with the tree just changing a dropdown in its own updatepanel takes forever. I have considered the size of viewstate and just raw HTML generated may be causing the delay but wouldn't that effect both browsers? Anyone have anyideas what is making it so slow in IE??? Thanks!
