• Magento and unsetting a custom boolean attribute

  - by Spongeboy

  Hi, I've added an attribute to a customer address entity. Attribute setup code is as follows- 'entity_type_id'=>$customer_address_type_id, 'attribute_code'=>'signature_required', 'backend_type'=>'int', 'frontend_input'=>'boolean', 'frontend_label' => 'Signature required', 'is_global' => '1', 'is_visible' => '1', 'is_required' => '0', 'is_user_defined' => '0', I have then - added attribute to model\entity\setup.php added a HTML field on the edit form I am now getting the attribute saved to the database when the checkbox is checked. However, it is not being unset when checkbox is unchecked (I'm guessing due to checkbox input not being 'post'-ed if unchecked. What is the best way to uncheck this? Should I add a default value of 0? Or unset/delete the attribute before save in the controller? Should I add get/set methods to the model?

• How do I view Visual Studio BuildLog.htm files without cutting and pasting into an external browser

  - by bgoodr

  This may or may not be specific to VS2005 (as that is the version I'm referring to for this question). I find often the case is that I see this in the Output panel inside Visual Studio 2>Build log was saved at "file://c:\\vsdll_example\MyExecRefsDll\Debug\BuildLog.htm" Now, since that looks and smells like a URL, I would have thought that I could simply left mouse click on it, or left mouse double-click on it, and a browser window of some sort would be displayed. No, that doesn't work. So, to view it, I have to cut and paste the "file://bla/bla/bla" part into an external window. Is there a way to set up Visual Studio to allow me to browse to that file directly, or view it inside Visual Studio IDE, or something to that effect, without the extra fiddling with cutting and pasting? Or is there some type of keybinding I'm not aware of? Thanks, bg

• Override Django inlineformset_factory has_changed() to always return True

  - by John

  Hi, I am using the django inlineformset_factory function. a = get_object_or_404(ModelA, pk=id) FormSet = inlineformset_factory(ModelA, ModelB) if request.method == 'POST': metaform = FormSet (instance=a, data=request.POST) if metaform.is_valid(): f = metaform.save(commit=False) for instance in f: instance.updated_by = request.user instance.save() else: metaform = FormSet(instance=a) return render_to_response('nodes/form.html', {'form':metaform}) What is happening is that if I change any of the data then everything works ok and all the data gets updated. However if I don't change any of the data then the data is not updated. i.e. only entries which are changed go through the for loop to be saved. I guess this makes sense as there is no point saving data if it has not changed. However I need to go through and save every object in the form regardless of whether it has any changes on not. So my question is how do I override this so that it goes through and saves every record whether it has any changes or not? Hope this makes sense Thanks

• Processing variable number of form fields

  - by a_m0d

  I am working on a form which displays information about orders. Each order has a unique id, but they are not necessarily sequential on the form. Also, the number of fields can vary (one field per row on the form). The input into the form will not be mapped straight into the database, but will be added to the current value in the database, and then saved. An example of the form is in the picture below - the callout on the right shows the id for each row. I know how to generate the form like this, but I can't work out how I can easily process each of these rows reliably. I also know how to give each of the fields a unique identifier, like name="row-23", but how can I translate that name so that I can update the related record in the database?

• How to archive old revisions from Apache SVN on linux server

  - by user1260729

  I have a site through which user can write their own Screenplays. This screenplays are saved in the form of revisions. Apache SVN has been installed. I want to save only the last 5 revisions for every user's document. But the problem is on the backend the all the revisions are stored in one folder called "Docsrepo" and its classified as 1000 revisions in 1 folder. and like this it has 234 folders. Meaning 234*1000 revisions. Now I want to archive all of this revision to keep only the last 5 revisions of each document. How do i do that?

• Rotate view of PDF on a WinForm

  - by Dabas

  I have to display a PDF inside a winform (c# on .net 2.0 framework). For now, I am using the ActiveX PDF control provided by Adobe. I have to disable the entire control so that a user can't print or save via right-click or hotkeys. Unfortunately, many of the documents need to be rotated (just viewed, not permanently saved that way). I'd like to allow them to rotate the view by pressing a button control. I've tried enabling the control then programmatically sending the hotkeys (ctrl shift +) using SendKeys and SendInput but the timing issues make this a non-viable solution. I've asked on the proper Adobe boards and they said it was not possible being that all of my clients will only have the reader version installed.

• Jquery .$.ajax is not working

• Best place to store large amounts of session data

  - by audiopleb

  I'm building an application that needs to store and re-use large amounts of data per session. So for example, the user selects a large list of list items (say 2000 or significantly more) which have a numeric value as their key then they save that selection and go off to another page, do something else and then come back to the original page and need to load their selections into that page. What is the quickest and most efficient way of storing and reusing that data? In a text file saved with the session id? In a temp db table? In the session data itself (db sessions so size isn't a limit) using a serialised string or using gzcompress or gzencode? Any advice or insight would be great! Thank you!!!!

• NHibernate: Dynamically swapping a single domain model between multiple physical data models

  - by Nigel

  Hi In this article Ayende describes how to map a single domain model to multiple physical data models. Is it possible to extend this principle such that the mapping can chosen dynamically? So for example, imagine we had an entity that could be written to the same physical schema in three ways depending on its current status, and lets assume that regardless of status each entity had a unique identifier. One solution would be to represent the entity in its different states with three separate classes: one for each mapping. Then the entity could be loaded and in order to change its state the entity could be mapped to a class representing one of its other states and then saved back to the schema, making use of a different mapping. I was wondering if it is at all possible to have the same entity represented by one class that held a status flag (kind of like a discriminator), and any save to the schema would choose the appropriate mapping based on the value of the status flag. Hopefully that made sense! Many thanks.

• problem in decreasing page's queries

  - by Mac Taylor

  hey guys i have a tag table in my php/mysql project that looks like this Table name : bt_tags Table fileds : tid,tag and for every story rows there is a filed named : tags Table name: stories table filed : tags that saved in this field as ids 1 5 6 space between them now problem : when using while loop to fetch all fields in story table , the page uses 1 query to show every stories' detail but for showing tag's names , i should query another table to find names , we have ids stored in story table now i used for loop between while loop to show tag names but im sure there is a better way to decrease page queries how can i improve this script and show tag's names without using *for loop ?* $result = $db->sql_query("SELECT * FROM ".STORY_TABLE." "); while ($row = $db->sql_fetchrow($result)) { //fetching other $vars ---- $tags_id = explode(" ",$row['tags']); $c = count($tags_id); for($i=1;$i<$c-1;$i++){ list($tag_name,$slug) = $db->sql_fetchrow($db->sql_query( 'SELECT `tag`,`slug` FROM `bt_tags` WHERE `tid` = "'.tags_id[$i].'" LIMIT 1' )); $sow_tags = '$tag_name,'; }

• whats the point of using template?

  - by netrox

  I am under the impression that if I set it as a template in Dreamweaver, any changes made should be saved to a new filename. I've copied the "template" that I made and sometimes I forget to save it as a different file name and it would overwrite previous web content. I just don't get the point of "save as template" if it works just like a document... it doesn't force me to save as a different filename. Common sense in me thinks that the software should evaluate like this, "if this is a template, always save as a different filename when it's modified so nothing is changed to the template, but rather a new file is created with the new content following that template." Am I missing something? Am I always doomed to using Save As...?

• Modifying object in AfterInsert / AfterUpdate

  - by Jean Barmash

  I have a domain object that holds results of a calculation based on parameters that are properties of the same domain object. I'd like to make sure that any time parameters get changed by the user, it recalculates and gets saved properly into the database. I am trying to do that with afterInsert (to make sure calculation is correct in the first place), and afterUpdate. However, since my calculation is trying to modify the object itself, it's not working - throwing various hibernate exceptions. I tried to put the afterUpdate code into a transaction, but that didn't help. I am afraid I am getting into a circular dependency issues here. The exception I am getting right now is: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [esc.scorecard.PropertyScorecard#27] Are the GORM events designed for simpler use cases? I am tempted to conclude that modifying the object you are in the middle of saving is not the way to go.

• Fault exception trashes a register causing a crash in [NSInvocation invoke]

  - by Mike Weller

  I have an NSOperation which fetches some objects from a core data persistent store and sums up a few totals. Sometimes an object is deleted while the operation in in progress, so a core data fault exception occurs. I try/catch the exception while summing to ignore it because I just want to skip objects that cannot be faulted in. However, when one of these fault exceptions occurs (and I swallow it) there is a crash after the invocation returns in [NSInvocation invoke]. It's a bad memory access when dereferencing the value in r10 which according to GDB on a successful run points to one of these: (gdb) x 0x38388348 0x38388348 <OBJC_IVAR_$_NSInvocation._retdata>: 0x00000008 If a fault exception occured a value of 0x02 is in the register which causes the crash. A quick google search tells me that r10 should be saved by the callee, meaning it is not being restored by whatever code is changing it when this exception occurs. Can anybody explain this? I'm not an expert when it comes to these kinds of low-level details

• Replacing whitespace with sed in a CSV (to use w/ postgres copy command)

  - by Wells

  I iterate through a collection of CSV files in bash, running: iconv --from-code=ISO-8859-1 --to-code=UTF-8 ${FILE} | \ sed -e 's/\"//g' | \ sed -e 's/, /,/g' \ > ${FILE}.utf8 Running iconv to fix UTF-8 characters, then the first sed call removes the double quote characters, and the final sed call is supposed to remove leading and trailing whitespace around the commas. HOWEVER, I still have a line like this in the saved file: FALSE,,,, 2.40,, The COPY command in postgres is kind of dumb, so it thinks " 2.40" is not valid syntax for a numeric value. Where am I going wrong w/ my processing of the CSV file? Thanks!

• Manipulating both unicode and ASCII character set in C#

  - by Murlex

  I have this mapping in my C# application string [,] unicode2Ascii = { { "&#3001;", "\x86" } }; ஹ - is the unicode value for a tamil literal "ஹ". This is the raw hex literal for the unicode value saved by MS Word as a byte sequence. I am trying to map these unicode value "strings" to a hex value under 255 (so as to accommodate non-unicode supported systems). I trying to use string.replace like this: S = S.replace(unicode2Ascii[0,0], unicode2Ascii[0,1]); However the resultant ouput has a ? instead of the actual hex 0x86 stored. Any pointer on how I could set the encoding for the second element of that array to something like windows-1252? Or is there a better way to do this conversion? thanks in advance

• How can I catch a change event from an HTML text field when a user clicks on a link after editing?

  - by Eric the Red

  Our webapp has a form with fields and values that change depending on values entered. Each time there is a change event on one of the form elements, we use an expensive AJAX call to update other elements on the page. This works great for selects, radio buttons and checkboxes. The issue comes in when a user adds content to a text field, and then clicks a link without taking the focus from the text field. The browser moves to a new page, and the contents of the text field are never saved. Is there an easy way to code around this? The AJAX call is too expensive to call with each key press. Here's an example of my Prototype code at the moment: $$('.productOption input.text').invoke('observe', 'change', saveChangeEvent);

• Safe way to support hosting files from asp.net mvc site

  - by ooo

  i have an asp.net-mvc site where users can add content and links and the data gets saved in a database. They now want the ability to upload attachments to pages and i wanted to figure out a few things: I have upload code that will upload files (pdfs, images, etc) but i wanted to see where i should be storing them. should i store them outside the website directory structure ? Is there any file types that i should be concerned with storing. I would basically have a file picker on the front end.

• Java File manipulation

  - by user69514

  So I have an application with a JFileChooser from which I select a file to read. Then I change some words and write a new file. The problem that I am having is that when I write the new file it's saved in the project directory. How do I save it in the same directory as the file that I chose using the JFileChooser. Note: I don't want to use the JFileChooser to choose the location. I just need to save the file in the same directory as the original file that I read.

  - by Sirber

  I have this function to prepare variable to be used in a SQL query: function sqlize($mInput) { if (!isset($mInput)) $mInput = "null"; elseif (strtolower($mInput) == "null") { } elseif (is_numeric($mInput)) { } elseif (is_string($mInput)) { $mInput = trim($mInput); $mInput = addslashes($mInput); $mInput = '"' . $mInput . '"'; } else $mInput = "null"; return $mInput; } I have a string "0004", which is going in a "varchar field", is cought by is_numeric, and is saved as "4" and not "0004". Is there a way to detect the padding and process it as a string? Thank you!

• afterTransactionCompletion not working

  - by Attilah

  I created an hibernate interceptor : public class MyInterceptor extends EmptyInterceptor { private boolean isCanal=false; public boolean onSave(Object entity, Serializable arg1, Object[] arg2, String[] arg3, Type[] arg4) throws CallbackException { for(int i=0;i<100;i++){ System.out.println("Inside MyInterceptor(onSave) : "+entity.toString()); } if(entity instanceof Canal){ isCanal=true; } return false; } public void afterTransactionCompletion(Transaction tx){ if(tx.wasCommitted()&&(isCanal)){ for(int i=0;i<100;i++){ System.out.println("Inside MyInterceptor(afterTransactionCompletion) : Canal was saved to DB."); } } } but the method afterTransactionCompletion doesn't get executed after a transaction is commited. I've tried all the ways I know of but I can't make it work. What's more surprising is that the onSave method works fine. Help ! Could this be due to this bug ? : http://opensource.atlassian.com/projects/hibernate/browse/HHH-1956 How can I circumvent this bug if it's the cause ?

• Fake Template Engine php

  - by user1464822

  i got an idea for making php template engine fast and user friendly but i'm not sure if it's good or bad. the idea is to create a fake template engine: creating a template editor in control panel that let user see something like this: <html> <head> <title>{title}</title> </head> <body> {content} </body> </html> what the editor actually does is to replace all php code like <?php echo $this->title; ?> to user friendly {title} but it's not really replacing it just in the view when the user save the template the template actually saved as fast pure php template. the question is this a good idea or bad ? your answers is highly appreciated.

• ASP.NET Session StateServer - is it possible to extract info about current sessions?

  - by Moe Sisko

  I'm looking into changing the ASP.NET session state mode of our application from SQLServer to StateServer (for performance reasons). In SQLServer mode, it is easy to extract information about the current sessions by querying SQL Server tables like ASPStateTempSessions. e.g. things like when each session was created, when it is due to expire, etc. You could even query the session state blob data to extract further application specific info (e.g. like the UserID, if it was saved in session state). This info was useful for administrators. Just wondering if anyone has managed to do something similar for StateServer mode.
