• Django/Mod_WSGI error: UnboundLocalError: local variable 'resolver' referenced before assignment

  - by ycseattle

  Hello, I've setup the Django with mod_wsgi and run into this error. I thought maybe the sys.path was not setup correctly but I tried everything I could think of with no luck. Any suggestions? The following is the apache2 log for the error: mod_wsgi (pid=2579): Exception occurred processing WSGI script '/home/myapp/myapp.wsgi'.

• Javascript || or operator with a undefinded variable

  - by bryan sammon

  I have been doing some reading lately one article I read was from Opera. http://dev.opera.com/articles/view/javascript-best-practices/ In that article they write this: Another common situation in JavaScript is providing a preset value for a variable if it is not defined, like so: if(v){ var x = v; } else { var x = 10; } The shortcut notation for this is the double pipe character: var x = v || 10; For some reason I cant get this to work for me. Is it really possible to check to see if v is defined, if not x = 10? --Thanks. Bryan

• Oracle sql: using bind variable for dates..

  - by user333747

  Here is a simple working query without bind variables: select * from table1 where time_stamp sysdate - INTERVAL '1' day; where time_stamp is of type DATE. I should be able to input any number of days in the above query using bind variable. So I tried the following and does not seem to work: select * from table1 where time_stamp sysdate - INTERVAL :days day; I tried entering the numeric input both as 10 and '10',for eg. You get ORA-00933 error on 10g.

• Redmine error undefined local variable 'usage' when recieving email

  - by fred

  I posted this on the Redmine forum about 20 days ago but am having no luck finding an answer, so I thought I'd see if I can find some love here: Somewhere during an upgrade to RM I lost the ability to have RM receive email. It was running just beautifully on 8.5. Some while back I upgraded and was not using the receive email feature for some time. At 9.2 and, now, 0.9.3.stable.3625, I'm getting an error in the procmail.log file: undefined local variable or method `usage' for #<RedmineMailHandler:0x6c14d34bb0a0> (NameError) I have a SVN install and used it, just tonight, to update the the 9.3 stable version. I walked through all the upgrade steps and everything seems to work fine, except for this. In rdm-redminehandler.rb I commented out the offending 'usage' line and got another error: 422 Unprocessable Entity

• [C#] Is variable assignment and reading atomic operation (threading)

  - by AStrangerGuy

  I was unable to find any reference to this in the documentations... Is assigning to a double (or any other simple type, including boolean) an atomic operation viewed from the perspective of threads? double value = 0; public void First() { while(true) { value = (new Random()).NextDouble(); } } public void Second() { while(true) { Console.WriteLine(value); } } In this code sample, first method is called in one thread, and the second in another. Can the second method get a messed up value if it gets its execution during assignment to the variable in another thread? I don't care if I recieve the old value, it's only important to receive a valid value (not one where 2 out of 8 bytes are set). I know it's a stupid question, but I want to be sure, cause I don't know how CLR actually sets the variables. Thanks

• JSLint reports "Unexpected dangling" character in an underscore prefixed variable name

  - by Zhami

  I know that some people consider the presence of a leading underscore to imply that a variable is "private," that such privacy is a fiction, and assume this is why JSLint reports such names with an error message. I use Google Analytics on a Web site I am building. I make reference to GA's variables, such as "_gaq." I am trying to get my JS code to be 100% JSLint clean (I'm not religious about my coding style, and so will go with Mr. Crockford's counsel). That said, I can't do anything about Google's variables names... so, I guess I can't get 100% "clean." I post here in case I've misunderstood the message, and can do something to comply with JSLint practices.

• How to join dynamic sql statement in variable with normal statement

  - by Oliver

  I have a quite complicated query which will by built up dynamically and is saved in a variable. As second part i have another normal query and i'd like to make an inner join between these both. To make it a little more easier here is a little example to illustrate my problem. For this little example i used the AdventureWorks database. Some query built up dynamically (Yes, i know here is nothing dynamic here, cause it's just an example.) DECLARE @query AS varchar(max) ; set @query = ' select HumanResources.Employee.EmployeeID ,HumanResources.Employee.LoginID ,HumanResources.Employee.Title ,HumanResources.EmployeeAddress.AddressID from HumanResources.Employee inner join HumanResources.EmployeeAddress on HumanResources.Employee.EmployeeID = HumanResources.EmployeeAddress.EmployeeID ;'; EXEC (@query); The normal query i have select Person.Address.AddressID ,Person.Address.City from Person.Address Maybe what i'd like to have but doesn't work select @query.* ,Addresses.City from @query as Employees inner join ( select Person.Address.AddressID ,Person.Address.City from Person.Address ) as Addresses on Employees.AddressID = Addresses.AddressID

• iPhone NSXMLParser parsing string and storing in a NSNumber variable and different data types

  - by anubhav

  Hi, I am trying to parse a XML File using NSXMLParser, I also have a Container class, in which I have a few instance variables. One of the elements that I am trying to parse in the XML is: <book sn="32.859669048339128" pn="-116.917800670489670"> I am trying to save the value of sn and pn in an instance variable of object Container: NSNumber *sn, NSNumber *pn. I want it so that when my parser get the attributeValues it can save it as a Double (or float) in those NSNumber pointers. Right now, all it does it just saves a string to the NSNumber. The Parser Code looks like this: if([elementName isEqualToString:@"book"]){ container = [[Container alloc] init]; container.sn=[attributeDict objectForKey:@"sn"]; container.pn=[attributeDict objectForKey:@"pn"]; } I want it so that the type of container.sn is initialized to a float or double. Any ideas how to do this? Thanks in advance!

• Coldfusion - variable field name when looping through database query results

  - by shifuimam

  I have a set of column names in a table - e.g. foo1, foo2, foo3, foo4. I want to refer to these column names dynamically through a loop: <cfloop index="i" from="1" to="4"> <cfset foo = Evaluate("query.foo" & i)> </cfloop> The above doesn't work - ColdFusion throws a "variable not defined" error, even though query.foo1 is a valid reference to the query results. How else can I do this?

• Jquery post success variable scope

  - by minirobot

  Hi, I'm trying to return the ajax success array from one function to another. For some reason I don't seem to be able to pass the data stored in a variable in the success part of the ajax function into the parent function to return. Thanks so much for any assistance. Here's a simplified version of the code: // make json_to_return global var json_to_return; function loop_through_data(){ // call the load_days function and put its array data into days_array var days_data = load_days(03,2010); // I'd like to be able to iterate through days_data here // // } function load_days(selectedMonth, selectedYear){ $.ajax({ type: "POST", dataType: "json", url: "../includes/get_availability.php", data: "month=" + selectedMonth + "&year=" + selectedYear, success: function(available_json){ json_to_return = available_json; }, error: function(msg){ alert("error " + msg); } }); return json_to_return; }

• SQL Server, temporary tables with truncate vs table variable with delete

  - by Richard

  I have a stored procedure inside which I create a temporary table that typically contains between 1 and 10 rows. This table is truncated and filled many times during the stored procedure. It is truncated as this is faster than delete. Do I get any performance increase by replacing this temporary table with a table variable when I suffer a penalty for using delete (truncate does not work on table variables) Whilst table variables are mainly in memory and are generally faster than temp tables do I loose any benefit by having to delete rather than truncate?

• When is calculating or variable-reading faster?

  - by Andreas Hornig

  hi, to be honest, I don't really know what the "small green men" in my cpu and compiler do, so I sometimes would like to know :). Currently I would like to know what's faster, so that I can design my code in a more efficient way. So for example I want to calclate something at different points in my sourcecode, when will it be faster to calculate it once and store it in a variable that's read and used for the next points it's needed and when is it faster to calculate it everytime? I think it's depending on how "complex" and "long" the calculation is and how fast then cache is, where variables are stored, but I don't have any clue what's faster :). Thanks for any reply to my tiny but important question! Andreas PS: perhaps it's important to know that I code in JAVA, but it's more a genral question.

• Wrapping variable width text in emacs lisp

  - by Jonathan Arkell

  I am hacking up a tagging application for emacs. I have got a tag cloud/weighted list successfully displaying on a buffer, but i am running into a snag. I need to be able to properly word-wrap the buffer, but I haven't a clue where to start. The font I am using is a variable width font. On top of that, each tag is going to be in a different size, depending on how many times it shows up on the buffer. Finally, the window that displays the tagcloud could be in a window that is 200 pixels wide, or the full screen width. I really have no idea where to start. I tried longlines mode on the tagcloud buffer, but that didn't work. Source code is at: http://emacswiki.org/cgi-bin/emacs/free-tagging.el

• jQuery, PHP, AJAX, "tu" variable beeing posted for no reason, shows in var_dump()

  - by Mattis

  A jQuery AJAX request .post()s data to page.php, which creates $res and var_dump()s it. $res: $res = array(); foreach ($_REQUEST as $key => $value) { if($key){ $res[$key] = $value; } } var_dump($res): array(4) { ["text1"]=> string(6) "mattis" ["text2"]=> string(4) "test" ["tu"]=> string(32) "deb6adbbff4234b5711cc4368c153bc4" ["PHPSESSID"]=> string(32) "cda24363cb9d3226bd37b2577ed0bc0b" } My javascript only sends text1 and text2: $.post("page.php",{ text1:"mattis", text2:"test" } What is the "tu" variable beeing sent? Apparantly it's very similar to the session id, but I've never seen it before. EDIT: It is sent in IE but not in FF.

• Pass a variable to a Symfony Form

  - by Juan Besa

  Hi, I am building a web application using Symfony 1.4 and Doctrine for a school and I want to make a very simple form to add a course to a student. The main problem I have is that in the drop down list I only want to show the courses in which the student is currently not enrolled. I already have a function in the model (in Student.class.php) which returns all the courses in which the student is not enrolled but the problem is I don't know how to pass the student to the configure() of the form. I have tried several options like passing it with the constructor of the form to a global variable or a special set method but none of them have worked. Is there any form to pass the student to the configure() method? Thanks!

• Javascript top variable in IE8

  - by Jim Rootham

  I am trying to reference a javascript function in a .js file loaded in my main page from an iframe using the 'top' variable. It works in FF, Safari, and IE6 but not in IE8. The snippet is (assigned to onmouseover): top.set_image(this, 'images/login_h.png') Where set_image is my function. The error is "Object does not support this function" Also, I have been looking for the definition of top. I can't find it in the ECMAScript specification or the w3schools site and Google is unhelpful (who'da thunk top was a common word?).
