  • django url tag performance

    - by zxygentoo
    I was trying to integrate django-voting into my project following the RedditStyleVoting instruction. In my urls.py, i did something like this: url(r'^sections/(?P<object_id>\d+)/(?P<direction>up|down|clear)vote/?$', vote_on_object, dict( model=Section, template_object_name='section', template_name='script/section_confirm_vote.html', allow_xmlhttprequest=True ), name="section_vote", then, in my template: {% vote_by_user user on section as vote %} {% score_for_object section as score %} {% vote_by_user user on section as vote %} {% score_for_object section as score %} {{ score.score|default:0 }} It takes over 1.3s to load the page, but by hard coding it like this: {% vote_by_user user on section as vote %} {% score_for_object section as score %} {{ score.score|default:0 }} I got 50ms. Just avoid the url tag resolving stuff I got a 20+ times performance improvement. Is there something I did wrong? If not, then what's the best practice here, should we do things the right way or the fast way?

  • Mod_Rewrite: Insert "/" between variables and values in URL

    - by Abs
    Hello all, I am attempting clean useful URLs using mod_rewrite. I am sure this is a common question but I am not so hot with mod_rewrite: I have this URL: http://mysite.com/user.php?user=fatcatmat&sort=popularv I want to be able to rewrite it like this: http://mysite.com/user/user/fatcatmat/sort/popularv (Is there a way to remove duplicates in a URL?) I think I have managed to do the removal of the PHP extension. RewriteRule ^(.*)\$ $1.php [nc] Is the above correct? For the separate pages, I would have something like this. RewriteRule ^/?user(/)?$ user.php Main Question: Its a bit tedious to do all the above but is there a MEGA rewrite rule that will just place "/" in between variables and their values and remove the .php extension from all pages? Thank you for any help.

  • How to do MVC form url formatting?

    - by dqhendricks
    I am using PHP. I want to create an MVC setup from scratch to learn more about how MVC works. I want to use clean urls with slashes as delimiters for the arguments. How do people do this when it comes to GET method forms? Or do people avoid GET method forms all together? As of right now the ways I can imagine are: Don't use GET method forms (although this makes it harder to let users bookmark/link in some cases). Use AJAX instead of form submission (although what do you do for SEO and JS disablers?). Have page submit to itself with post method, then reform the post vars into an url, then rerout to that url using headers (seems like wasted resources). Any suggestions or suggested reading welcome.

  • Spring+JSP url building best practices

    - by dotsid
    I wonder if there are any good practices for addressing Spring controllers in JSP. Suppose I have controller: @Controller class FooController { // Don't bother about semantic of this query right now @RequestMapping("/search/{applicationId}") public String handleSearch(@PathVariable String applicationId) { [...] } } Of course in JSP I can write: <c:url value="/search/${application.id}" /> But it's very hard to change url then. If you familiar with Rails/Grails then you now how this problem resolved: redirect_to(:controller => 'foo', :action = 'search') But in Spring there is so much UrlMappers. Each UrlMapper have own semantic and binding scheme. Rails alike scheme simply doesn't work (unless you implement it yourself). And my question is: are there any more convenient ways to address controller from JSP in Spring?

  • SEO Url Redirect/Rewrite Using Database Managed Links

    - by user204245
    I have searched left and right. And i am trying to find a script or a method on how I can store links in database and use them for redirection. This is an E-commerce project and I am looking for something to manage Product and system URL from database. Something Similar like magneto dose. Basically anything after the domain say like domain.com/demo/12/my_iphone so now demo/12/my_iphone will be sent to database for querry and in databases there will be a destination URL which could be productlisting.php?searchstring=iphones so the user will see link domain.com/demo/12/my_iphone but actualy he will be seeing productlisting.php?searchstring=iphones basically demo/12/my_iphone = productlisting.php?searchstring=iphones and tomorrow if the user want to edit demo/12/my_iphone to demo/12/myiphone he can just do so using simple form which will update in the database. How can i achieve this ?

  • Simple rails routing / url question

    - by justinbach
    I'm using Ryan Bates' nifty authentication in my application for user signup and login. Each user has_many :widgets, but I'd like to allow users to browse other users' widgets. I'm thinking that a url scheme like /username/widgets/widget_id would make a lot of sense--it would keep all widget-related code in the same place (the widgets controller). However, I'm not sure how to use this style of URL in my app. Right now my codebase is such that it permits logged-in users to browse only their own widgets, which live at /widgets/widget_id. What changes would I need to make to routes.rb, my models classes, and any place where links to a given widget are needed? I've done Rails work before but am a newb when it comes to more complicated routing, etc, so I'd appreciate any feedback. Thanks for your consideration!

  • Rewriting URL in AJAX application

    - by Artem Moskalev
    I am making a simple online application. I have a navigation bar with a few buttons and one "div" into which all the new contents will be loaded dynamically i.e. when I click "About", it will load the page parts into the "div" without reloading the whole page with .load() function. The problem is: what if I need to give a link to the Documents section of my web site, or the user wants to store this kind of link, the url is not rewritten when browsing my site. when the user stores the default link it will always link him to the default "Home" part. How can I rewrite the URL and what is the most correct way to do this?

  • html/php: how to handle absolute url's?

    - by YuriKolovsky
    Is the html tag safe to use in terms of browser support? Or should I generate a root path with PHP which i then add like this <a href="<?=BASE?>somepage.html">somepage</a> which makes up a absolute url. using the base tag like this <base href="<?=BASE?>" /> I am then able to use links like this <a href="somepage.html">somepage</a> now I am fully aware that it would be much easier to just do this without using the base tag: <a href="/somepage.html">somepage</a> but how do I test locally then with a base url of http://localhost/testsite/ ???

    - by Amash
    I am creating a website using IonCube. I can use some PHP coding in the HTML page templates, however, I would like to know how to get the FULL URL plus a link when I click on it. For example, My current URL is: http://example.com/site_search.php?option_1=1&option_2=1 and when I click on a link, it directs me to another added option, so the result will be: http://example.com/site_search.php?option_1=1&option_2=1&option_3&option_4=8 As you have seen, these are options, and users can select anything. I appreciate your help - Thanks

  • Explode URL Query String Issue

    - by Ian McAbee
    PHP newbie here.. I am trying to create a function where the user is redirected back to the previous page after adding an item to their cart. However, when they are redirected back with the code below it leaves a duplicate of the directory (ie. example.com/catalog/garden-tools/garden-tools function custom_add_to_cart_redirect() { $_SERVER['REQUEST_URI_PATH'] = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); $url = explode('/', rtrim($_SERVER['REQUEST_URI_PATH'], '/')); return $url[3]; } A print_r reveals the following: Array ( [0] => [1] => thefarmshop [2] => catalog [3] => garden-tools [4] => gardening-glove ) What could the issue be?

  • Twitter URL encoding

    - by Rich
    Hi, We're about to launch a little twitter Christmas competition, and I've run into a little snag. To enter, people will need to post a tweet in the following format: @user blah, blah, blah #hashtag Currently, I have a form where they enter their answer (the blah, blah, blah) and a PHP script which encodes the entire statement and adds on the twitter url: http://www.twitter.com/home?status=%40user%20blah%2Cblah%2Cblah%20%23hashtag Then takes the user to twitter and puts the status in the update field. However, whilst the spaces (%20) are decoded fine the @ and # characters remain as %40 & %23 respectively, even when the tweet is posted. I cannot put the actual characters in the url as twitter mistakes this for a search. Is there any way to solve this? I'd like to do it without requiring username & password etc if possible. Any help will be greatly appreciated.

  • Windows Server 2003 R2 Standard: Locks MS Office files, but not Adobe .AI and .PSD files?

    - by Bruce Garlock
    We have some shares setup on a Windows 2003 R2 server, and the MS Office files people save behave properly: The first person to open the file gets read/write, and the second person to open the file while the first person still has the file open, gets a read-only version. This is not true for the graphics files, like Adobe Illustrator .AI files, and Photoshop .PSD files. Anyone who goes to open these files has full read/write, even if someone else is already working on the file! This has lead to numerous file corruption issues, as well as other lost work, since it always saves the last changes to the file. How do we get Windows to properly lock these files so when someone is working on a file, and someone else wants to open one, they get read-only access? Many thanks, Bruce

  • File locked / read-only

    - by oshirowanen
    On a networked computer, I have a file which is coming up as read-only because someone else has it open. This is not true. This is a file stored locally on the computer and it is not being used by anyone else. I can login to the same computer using a different user, and the file opens up fine. I just get the issue with a particular user account. Other than deleting theses account/profile and creating it again, how can I unlock this file? Double clicking on this file gives me a message saying The file is locked for editing by another user, or the file (or the folder in which it is located,) is marked as read-only, or you specified that you wanted to open this file read-only. I don't think the folder is locked, because I can use other files in that folder fine, it's just 1 particular file which is causing this issue. I know that only 1 user is using this file as the file is on his c: and the same file works fine if he logs off to allow another user to log in.

  • Fragmented Log files could be slowing down your database

    - by Fatherjack
    Something that is sometimes forgotten by a lot of DBAs is the fact that database log files get fragmented in the same way that you get fragmentation in a data file. The cause is very different but the effect is the same – too much effort reading and writing data. Data files get fragmented as data is changed through normal system activity, INSERTs, UPDATEs and DELETEs cause fragmentation and most experienced DBAs are monitoring their indexes for fragmentation and dealing with it accordingly. However, you don’t hear about so many working on their log files. How can a log file get fragmented? I’m glad you asked. When you create a database there are at least two files created on the disk storage; an mdf for the data and an ldf for the log file (you can also have ndf files for extra data storage but that’s off topic for now). It is wholly possible to have more than one log file but in most cases there is little point in creating more than one as the log file is written to in a ‘wrap-around’ method (more on that later). When a log file is created at the time that a database is created the file is actually sub divided into a number of virtual log files (VLFs). The number and size of these VLFs depends on the size chosen for the log file. VLFs are also created in the space added to a log file when a log file growth event takes place. Do you have your log files set to auto grow? Then you have potentially been introducing many VLFs into your log file. Let’s get to see how many VLFs we have in a brand new database. USE master GO CREATE DATABASE VLF_Test ON ( NAME = VLF_Test, FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.ROCK_2008\MSSQL\DATA\VLF_Test.mdf', SIZE = 100, MAXSIZE = 500, FILEGROWTH = 50 ) LOG ON ( NAME = VLF_Test_Log, FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.ROCK_2008\MSSQL\DATA\VLF_Test_log.ldf', SIZE = 5MB, MAXSIZE = 250MB, FILEGROWTH = 5MB ); go USE VLF_Test go DBCC LOGINFO; The results of this are firstly a new database is created with specified files sizes and the the DBCC LOGINFO results are returned to the script editor. The DBCC LOGINFO results have plenty of interesting information in them but lets first note there are 4 rows of information, this relates to the fact that 4 VLFs have been created in the log file. The values in the FileSize column are the sizes of each VLF in bytes, you will see that the last one to be created is slightly larger than the others. So, a 5MB log file has 4 VLFs of roughly 1.25 MB. Lets alter the CREATE DATABASE script to create a log file that’s a bit bigger and see what happens. Alter the code above so that the log file details are replaced by LOG ON ( NAME = VLF_Test_Log, FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.ROCK_2008\MSSQL\DATA\VLF_Test_log.ldf', SIZE = 1GB, MAXSIZE = 25GB, FILEGROWTH = 1GB ); With a bigger log file specified we get more VLFs What if we make it bigger again? LOG ON ( NAME = VLF_Test_Log, FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.ROCK_2008\MSSQL\DATA\VLF_Test_log.ldf', SIZE = 5GB, MAXSIZE = 250GB, FILEGROWTH = 5GB ); This time we see more VLFs are created within our log file. We now have our 5GB log file comprised of 16 files of 320MB each. In fact these sizes fall into all the ranges that control the VLF creation criteria – what a coincidence! The rules that are followed when a log file is created or has it’s size increased are pretty basic. If the file growth is lower than 64MB then 4 VLFs are created If the growth is between 64MB and 1GB then 8 VLFs are created If the growth is greater than 1GB then 16 VLFs are created. Now the potential for chaos comes if the default values and settings for log file growth are used. By default a database log file gets a 1MB log file with unlimited growth in steps of 10%. The database we just created is 6 MB, let’s add some data and see what happens. USE vlf_test go -- we need somewhere to put the data so, a table is in order IF OBJECT_ID('A_Table') IS NOT NULL DROP TABLE A_Table go CREATE TABLE A_Table ( Col_A int IDENTITY, Col_B CHAR(8000) ) GO -- Let's check the state of the log file -- 4 VLFs found EXECUTE ('DBCC LOGINFO'); go -- We can go ahead and insert some data and then check the state of the log file again INSERT A_Table (col_b) SELECT TOP 500 REPLICATE('a',2000) FROM sys.columns AS sc, sys.columns AS sc2 GO -- insert 500 rows and we get 22 VLFs EXECUTE ('DBCC LOGINFO'); go -- Let's insert more rows INSERT A_Table (col_b) SELECT TOP 2000 REPLICATE('a',2000) FROM sys.columns AS sc, sys.columns AS sc2 GO 10 -- insert 2000 rows, in 10 batches and we suddenly have 107 VLFs EXECUTE ('DBCC LOGINFO'); Well, that escalated quickly! Our log file is split, internally, into 107 fragments after a few thousand inserts. The same happens with any logged transactions, I just chose to illustrate this with INSERTs. Having too many VLFs can cause performance degradation at times of database start up, log backup and log restore operations so it’s well worth keeping a check on this property. How do we prevent excessive VLF creation? Creating the database with larger files and also with larger growth steps and actively choosing to grow your databases rather than leaving it to the Auto Grow event can make sure that the growths are made with a size that is optimal. How do we resolve a situation of a database with too many VLFs? This process needs to be done when the database is under little or no stress so that you don’t affect system users. The steps are: BACKUP LOG YourDBName TO YourBackupDestinationOfChoice Shrink the log file to its smallest possible size DBCC SHRINKFILE(FileNameOfTLogHere, TRUNCATEONLY) * Re-size the log file to the size you want it to, taking in to account your expected needs for the coming months or year. ALTER DATABASE YourDBName MODIFY FILE ( NAME = FileNameOfTLogHere, SIZE = TheSizeYouWantItToBeIn_MB) * – If you don’t know the file name of your log file then run sp_helpfile while you are connected to the database that you want to work on and you will get the details you need. The resize step can take quite a while This is already detailed far better than I can explain it by Kimberley Tripp in her blog 8-Steps-to-better-Transaction-Log-throughput.aspx. The result of this will be a log file with a VLF count according to the bullet list above. Knowing when VLFs are being created By complete coincidence while I have been writing this blog (it’s been quite some time from it’s inception to going live) Jonathan Kehayias from SQLSkills.com has written a great article on how to track database file growth using Event Notifications and Service Broker. I strongly recommend taking a look at it as this is going to catch any sneaky auto grows that take place and let you know about them right away. Hassle free monitoring of VLFs If you are lucky or wise enough to be using SQL Monitor or another monitoring tool that let’s you write your own custom metrics then you can keep an eye on this very easily. There is a custom metric for VLFs (written by Stuart Ainsworth) already on the site and there are some others there are very useful so take a moment or two to look around while you are there.

  • Open an Excel htm URL via iFrame in a separate browser

    - by Mark Robinson
    I have some URLs in an Excel file which I have saved as a .htm (webpage) file. I then view these in a browser via our wiki (MediaWiki). This is done using an iFrame embedded in the wiki page. So, just for clarity, the link is in a htm file viewed via an iFrame in a wiki page. When I click on that link, it opens inside the iFrame. What I want is for it to open in a new browser window. (This should be the user's default browser since some use Internet Explorer and some Firefox.) The final twist is that some users have Windows XP and some Solaris. Help greatly appreciated.
