• How to debug Fluent nHibernate

  - by Matt Thrower

  Hi, I'm having some trouble with Fluent nHibernate. I added a column to a table and I thought I'd correctly changed the mappings and the connected data objects to correctly reflect this. However when I tried to run my application again I kept getting this error: System.Data.SqlClient.SqlException: Invalid column name 'Workflow_id'. I really couldn't see what the problem was with the changes I'd made so I reverted back to the original versions of the mapping and data object files from source control and removed the offending column from the database. But I'm still getting the same error. I'd like some advice on how to debug this. The SQL that gets reported on the error is semi-nonsensical: SELECT regions0_.Page_id as Page5_1_, regions0_.Id as Id1_, regions0_.Id as Id27_0_, regions0_.RegionId as RegionId27_0_, regions0_.RegionTemplate_id as RegionTe3_27_0_, regions0_.Workflow_id as Workflow4_27_0_ FROM [Region] regions0_ WHERE regions0_.Page_id=? And it won't execute as valid SQL anyway. Any ideas as to where to go from here?

• JQuery cookie access has stopped working for GAE app

  - by Greg

  I have a google app engine app that has been running for some time, and some javascript code that checks for a login cookie has suddenly stopped working. As far as I can tell, NO code has changed. The relevant code uses the jquery cookies plugin (jquery.cookies.2.2.0.min.js)... // control the default screen depending // if someone is logged in if( $.cookies.get('dev_appserver_login') != null || $.cookies.get('ACSID') != null ) { alert("valid cookie!") $("#inventory-container").show(); } else { alert("INvalid cookie!") $("#welcome-container").show(); } The reason for the two checks is that in the GAE SDK, the cookies are named differently. The production system uses 'ACSID'. This if statement works in the SDK and now fails 100% of the time in production. I have verified that the cookie is, in fact, present when I inspect the page. Thoughts?

• How to model dependency injection in UML ?

  - by hjo1620

  I have a Contract class. The contract is valid 1 Jan 2010 - 31 Dec 2010. It can be in state Active or Passive, depending on which date I ask the instance for it's state. ex. if I ask 4 July 2010, it's in state Active, but if I ask 1 Jan 2011, it's in state Passive. Instances are created using constructor dependency injection, i.e. they are either Active or Passive already when created, null is not allowed as a parameter for the internal state member. One initial/created vertex is drawn in UML. I have two arrows, leading out from the initial vertex, one leading to state Active and the other to state Passive. Is this a correct representation of dependency injection in UML ? This is related to http://stackoverflow.com/questions/2779922/how-model-statemachine-when-state-is-dependent-on-a-function which initiated the question on how to model DI in general, in UML.

• Worked Example of Digital Signature Algorithm

  - by drelihan

  Hi Folks, Does anybody have a DSA worked example with simple values on how to calculate r,s and verify v == r. As this standard has been around awhile and is implemented in librarys e.g. the Java Cryptography Extension I'm finding it very hard to find an example of how the algorithm works. Compute r=(gk mod p) mod q Compute s=(k-1 * (x * r + i)) mod q Verifying a signature; again i is the input, and (r,s) is the signature. u1 = (s-1 * i) mod q u2 = (s-1 * r) mod q v = ((gu1 * yu2) mod p) mod q If v equals r, the signature is valid. Thanks,

• How to parse a Zend URL for parameters?

  - by wizzard

  I am trying to extract the GET parameters from a ZF REST URL. It's not the current request and I don't want to call the URL or execute the route, I just need the parameters. I'm looking for a utility function like parse_url(), but for the Zend REST format. Is there one, or do I have to reinvent the wheel? I've tried a few things like creating a new Zend_Controller_Request_Http but the parameters aren't being populated. It is a valid HTTP URL. Edit: Upon request, a sample Zend URL: http://localhost/index/index/param1/foo/param2/bar So I am just trying to get param1 and param2 out of this URL.

• Starting Javascript

  - by user288245

  Hi guys, a couple of questions (never done javascript before). Below is part of the what happens on submit, what is something, the action, the php script its sent to? Also is there any software you guys reccomend for checking you're javascript, like the equivalent of an ide? im using notepad++. Is the rest the right sort of idea? I'm using several else ifs for each method, checking valid == true. <SCRIPT LANGUAGE="JavaScript"> <form action="something" onsubmit="return ok()"> function ok() { if (validate_Info() == false) { alert('Please enter a name'); return false; } else if else if

• Filter the datagridview column based on the current row of another column in C#

  - by user286546

  I have a datagridview that is populating columns from different table. I want to filter the column based on another column of the current row. I tried to use the cell enter event of the datagridview and then filtered the column by filtering the binding source on the column of the current row. private void lINKDataGridView_CellEnter(object sender, DataGridViewCellEventArgs e) { this.pROBLEMBindingSource.Filter = "item_id = " + this.lINKDataGridView.Rows[e.RowIndex].Cells[dataGridViewTextBoxColumn4.Index].Value + ""; } This is how I am filtering the "problem " binding source on the cell enter event of the datagridview . It is working fine but I am getting an error- being: System.ArgumentException: DataGridViewComboBoxCell value is not valid. Any suggestion

• Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

  - by James A. Rosen

  I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]

• Code Signing Identity does not match in my keychain, for mac app store developing?

  - by larntin

  hi, 1, I already download the "Apple Worldwide Developer Relations Certification Authority",and add it into my keychain. 2, My team leader already had created two Cers for Mac App store developing, I download and add it into my keychain. 3, I used two methods to sign my add, but failed all. First, add code sign section in my .xcodeproj(3.2.5). Second, I used script: productbuild --component ./bin/MAS_Release/MyApp.app /Applications --sign "3rd Party Mac Developer Application: My Company Co., Ltd." --product ./src/MyApp/MyApp-Info.plist MyApp.pkg But it failed with information: Code Signing Identity '3rd Party Mac Developer Application: My Company Co., Ltd.' does not match any valid, non-expired, code-signing certificate in your keychain. I observed that my certifications in keychain don't have small trangle. how make the small trangle absence?(when I'am importing the Cers from my Agent, it don't have the trangle absence)

• MySQL Conventions?

  - by Moe

  Hi There, I just moved my website to a new server (Shared to VPS) I expected errors, and the only error that is really puzzling me is this SQL statement. echo mysql_query("SELECT COUNT(*) FROM users_online_now") This returns nothing! And if I try the mysql_num_rows, it returns mysql_num_rows(): supplied argument is not a valid MySQL result resource.. If I query another table though eg: echo mysql_query("SELECT COUNT(*) FROM users") It works fine. I'm guessing it's something to do with the naming of the table? It worked fine on my previous host, is there some setting I should modify?

• Is this __import__ functionality correct?

  - by Jason Baker

  I have a package named jiva_tasks, which I'm trying to import via celery (using the CELERY_IMPORTS attribute of celeryconfig. The import statement that celery is using is this: __import__(module, [], [], ['']) Oddly enough, when this syntax is used, the module gets imported twice, once as jiva_tasks and another time as jiva_tasks. (with a period at the end). Now, chances are good that celery should be passing in globals rather than an empty list, but this seems broken to me. It seems odd that even if given the wrong arguments, __import__ would import something that isn't a valid python module name. I know that the way to fix this is to pass in globals, but I want to understand why I'm getting this result. Is this a bug, or is there something I don't understand about how __import__ is working? Update: It also seems to be working fine if I use importlib.

• Can't inherit from auto_str without problems

  - by fret

  What I want to do is this: #include <memory> class autostr : public std::auto_ptr<char> { public: autostr(char *a) : std::auto_ptr<char>(a) {} autostr(autostr &a) : std::auto_ptr<char>(a) {} // define a bunch of string utils here... }; autostr test(char a) { return autostr(new char(a)); } void main(int args, char **arg) { autostr asd = test('b'); return 0; } (I actually have a copy of the auto_ptr class that handles arrays as well, but the same error applies to the stl one) The compile error using GCC 4.3.0 is: main.cpp:152: error: no matching function for call to `autostr::autostr(autostr)' main.cpp:147: note: candidates are: autostr::autostr(autostr&) main.cpp:146: note: autostr::autostr(char*) I don't understand why it's not matching the autostr argument as a valid parameter to autostr(autostr&).

• Solution to combine two submit buttons.. doing two different things from the same input

  - by zac

  I am trying to figure out how to combine two different forms, both require the same input but they do two different things. One form sends a request to the ecommerce platform to get the order status, and another form takes the same order number and returns a tracking code from USP or USPS. I am looking for some guidance on how I could combine these two actions.. one is currently using the POST method and the other GET. Here is an example .. so one is This one runs a validation script to confirm the order number is valid and then returns the order info if it is the second form is sending a get request to an asp file that is generating the proper tracking numbers. Can someone please point me to how I could begin to tackle this?

• Resource interpreted as other but transferred with MIME type text/html.

  - by Zhami

  I'm transferring fragments of HTML via Ajax. Safari (4.0.5) reports: "Resource interpreted as other but transferred with MIME type text/html." The file name of the file I get has a .html extension. The server does set the header for this: Content-Type:text/html As I said, the content is a fragment of HTML, which is injected into the page (with jQuery). The contents of the file look like: <html> ... some valid html ... </html> What else might Safari need to see to make it interpret the received content as HTML? TIA.

• is this a secure approach in ActiveRecords in Rails?

  - by Adnan

  Hello, I am using the following for my customers to unsubscribe from my mailing list; def index @user = User.find_by_salt(params[:subscribe_code]) if @user.nil? flash[:notice] = "the link is not valid...." render :action => 'index' else Notification.delete_all(:user_id => @user.id) flash[:notice] = "you have been unsubscribed....." redirect_to :controller => 'home' end end my link looks like; http://site.com/unsubscribe/32hj5h2j33j3h333 so the above compares the random string to a field in my user table and accordingly deletes data from the notification table. My question; is this approach secure? is there a better/more efficient way for doing this? All suggestions are welcome.

• Parenthesis operator in C. What is the effect in the following code

  - by Andre

  Hi everyone, I was playing with a macro to enable/disable traces when I came out with the following code when the macro is disabled: int main { ("Hello world"); } This code is valid and I got the desired effect (nothing happens when the macro is disabled) but I couldn't figure out what exactly is happening. Is the compiler seeing the parenthesis as a "nameless" method declaration? To make it clearer the code is : #ifdef TRACE #define trace printf("%s %d -> ",__FILE__, __LINE__);printf else #define trace #endif int main { trace("Hello world"); } Thanks in advance.

• Is it possible to hide columns in jQuery Grid by default?

  - by Toran Billups

  I have been working with the jQuery Grid the past few days and one thing I have not found any documentation on yet is the ability to hide a column by default. The reason I want this is that I'm building my JSON w/ every property of my object yet my grid might only show 75% of these as valid columns. I want the ability to pass back more JSON than I actually use, and one way I thought to accomplish this would be to hide the columns I'm not using. Any other suggestions are welcome, but I would prefer the ability to push down a larger list of JSON than I actually use by default.

• jQuery .getJSON() Not Parsing All Objects

  - by Brad

  I'm using jQuery's .getJSON function to parse a set of search results from a Google Search Appliance. The search appliance has an xslt stylesheet that returns the results as JSON data, which I validated with both JSONLint and Curious Concept's JSON Formatter. According to FireBug, the full result set is returned from the XMLHTTPRequest, but I tried dumping the data (with jquery.dump.js) and it only ever parses back the first result. It does successfully get all the Google Search Protocol stuff, but it only ever sees one "R" object (or individual result). Has anybody had a similar problem with jQuery's .getJSON? I know it likes to fail silently if the JSON is not valid, but like I said, I validated the results with several validators and it should be good to go. Edit: Clicking this link will show you the JSON results returned for a search for the word "google": http://bigbird.uww.edu/search?client=json_frontend&proxystylesheet=json_frontend&proxyrefresh=1&output=xml_no_dtd&q=google jQuery only retrieves the first "R" object, even though all "R" objects are siblings.

• How to wrap Plone authentication around a third-party servlet?

  - by smocking

  We're using Plone to serve up some third-party middle-ware. Unfortunately the middle-ware has a particular servlet that gets invoked from a Java applet and doesn't do any kind of authentication. I would like to firewall this off and somehow wrap authentication around it, preferably using the existing session that users will have on Plone. My first idea was to configure nginx (which we're using as the reverse proxy) to check the cookie and only proxy if the user has a valid session (along the lines of this example). However, how to check the session ID against Plone, since it's all stored in the Zope database? Alternatively we could have a Plone python script that basically passes everything along to the back-end after authenticating, but I'm not sure how to do that. Any suggestions? Or alternative ideas?
