  • Using Django view variables inside templates

    - by William
    Hi, this is a rather basic question (I'm new to Django) but I'm having trouble using a variable set in my view inside my template. If I initialize a string or list inside my view (i.e. h = "hello") and then attempt to call it inside a template: {{ h }} there is neither output nor errors. Similarly, if I try to use a variable inside my template that doesn't exist: {{ asdfdsadf }} there is again no error reported. Is this normal? And how can I use my variables within my templates. Thanks!

  • filter log file by defining regexes

    - by fmpdmb
    I have some HUGE log files (50Mb; ~500K lines) I need to start filtering some of the crap out of. The log files are being produced using log4j and have the basic pattern of: [log-level] date-time class etc, etc log-message I'm looking for a way that I can identify a regex start and regex end (or something similar) that will filter out the matching entries from the file so I can more easily wade through these massive files. I'm sure I could write a java program to accomplish this task, but I thought I'd ask the community before going down that path. Thanks in advance.

  • Deserialising Json to derived types in Asp.Net Web API

    - by IoChaos
    I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

  • How to change PHP's eregi to preg_match

    - by jasondavis
    I need help, below is a small VERY basic regex to somewhat validate an email, I do realize it does not work the greatest but for my needs it is ok for now. It currently uses PHP's eregi function which php.net says is now a depreciated function and I should use preg_match instead, simply replacing erei with preg_match does not work, can someone show me how to make it work? function validate_email($email) { if (!eregi("^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$", $email)) { echo 'bad email'; } else { echo 'good email'; } } function validate_email($email) { if (!preg_match("^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$", $email)) { echo 'bad email'; } else { echo 'good email'; } }

  • iPhone MVC Question

    - by HM1
    Hi, I'm bit of a newbie and had a basic question regarding adhering to the MVC model in iPhone coding. How do I setup a Model class that holds my data and connect it to different controllers in the following setup: Using Interface Builder, I created a tab controller in which - Tab #1 has a Nav Controller and a hierarchy of View Controllers. - Tab #2 has a View Controller So with what I have now, the View Controller under Tab #1 alloc init's the model class and I know how to pass the model from one ViewController to the next in the Navigation Hierarchy where it can pass the data and/or be updated with new data. Question is how to pass it from Tab #1's View Controller to Tab #2 View Controller as there is no code linking the two??? Thanks in advance, Hiren.

  • Updating display of elements on the web page without refreshing the whole page

    - by ivorossi3
    Last time I coded a web application was almost 10 years ago. I used Java/JSP/HTML/CSS etc. I've been coding non-web applications only ever since. When I look at modern sites now (like this one), I realize how my web development skills are obsolete. Maybe the most obvious "feature" that I wouldn't know how to implement now is the update of elements on the page after user input without having to refresh the whole page (e.g. the voting/downvoting here updates the vote count without reloading the whole page). What are the basic technologies behind this?

  • iPhone - Landscape Only App

    - by Robert
    Hello all! I am trying to make an app that will only be viewed in Landscape. I have looked up some tutorials (albeit older ones) and have done the following: -set up the info.plist to include a key for uiinterfaceorientation -in the main view controller I have set the frame to be 480 x 320 Now, the first screen loads up ok. Everything is where it should be and whatnot. However, if I click a button that is set to present a modal view controller nothing happens. Everything is linked and coded correctly but nothing happens when I press the button. Am I doing something wrong with trying to force landscape? At it's basic, this question is a how do you effectively make an app that will only be in landscape mode? Thanks for any help.

  • Where is a Web Development Career fueled by Passion? [closed]

    - by JMC Creative
    Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.

  • Silverlight Binding: User controls inside datagrid.

    - by Eric
    I have a DataGrid in my silverlight app that has a few columns. A couple basic columns bound with no issues. One column has a UserControl in it and the XAML is as follows: <data:DataGridTemplateColumn Header="" CanUserSort="True" Width="107"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <local:StaticPageEnlistment EnlistmentName="{Binding SiteName}" Width="400" Height="150"/> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> So I have a public property that's a string called EnlistmentName that I have bound to the SiteName value. I use this same "{Binding SiteName}" in all my other colums with no issues, why can't the user control accept the same binding string?

  • What would you like to see in a book about Rails 3?

    - by Ryan Bigg
    Hello, I'm thinking of writing a book about Rails 3 and I have a basic idea of what I want to write about, but really what I need is that little bit of polish from the community. The book is planned to cover: A little bit of Ruby Version control using Git Testing using RSpec & Cucumber Life without Rails (Rack) Developing an application in Rails (vague, I know, sorry! Work in progress) Javascript testing using Selenium Background processing Document databases (a tentative maybe, at this stage) Monitoring an application And a little more. So, I leave this question for you: What do you want to see in a book about Rails 3, which goes from "This is Rails" to "This is how Rails scales"?

  • Change CkEditor's background color with jQuery methods

    - by user198003
    I need to change background color of CkEditor, on some basic jQuery methods, like ready, change, etc. Tried with things like: $(document).on('click','.change-task-status', function(e){ $(".cke_editable").css("background-color", 'red'); }) ... but nothing happens. Can you help me how to achieve this? Thank you in advance! PS. yes, I do have jQuery adapter loaded on page. UPDATE: Some improvement is made - when I run next code in console, it changes background color $( ".cke_wysiwyg_frame" ).contents().find( ".cke_editable" ).css( "background-color", "#BADA55" ); Now just to find why it does not execute in code...

  • Ranged integers in .NET (or C#)

    - by Mal Ross
    Am I being blind, or does the .NET framework not provide any kind of ranged integer class? That is, a type that would prevent you setting a value outside some given bounds that are not the full range of the basic data type. For example, an integer type that would restrict its values to between 1 and 100. Showing my age here, but back in '93, I remember using that sort of thing in Modula-2 (eeek!), but I've not seen explicit framework / language support for it since. Am I just missing something, or is it a case of "it's so simple to make your own that the framework doesn't bother"? Cheers.

  • PHP Framework Benefits / Downfalls

    - by Lizard
    I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can deffinately seen the benefits of MVC keeping the logic sperate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

  • gwt - Using List<Serializable> in a RPC call?

    - by Garagos
    I have a RPC service with the following method: public List<Serializable> myMethod(TransactionCall call) {...} But I get a warning when this method is analyzed, and then the rpc call fails Analyzing 'my.project.package.myService' for serializable types Analyzing methods: public abstract java.util.List<java.io.Serializable> myMethod(my.project.package.TransactionCall call) Return type: java.util.List<java.io.Serializable> [...] java.io.Serializable Verifying instantiability (!) Checking all subtypes of Object wich qualify for serialization It seems I can't use Serializable for my List... I could use my own interface instead (something like AsyncDataInterface, wich implements the Serializable interface) but the fact is that my method will return a list custom objects AND basic objects (such as Strings, int....). So my questions are: Is it a standart behaviour? (I can't figure out why I can't use this interface in that case) Does anyone have a workaround for that kind of situation?

  • variable being weirdly deleted

    - by calccrypto
    im having a weird problem with one variable: its not being recognized but its still printing. i would post my code, but it is massive. the basic idea is: # pseudocode def function(stuff): <do stuff> # These are the only 2 conditions if tag == 3: pka = <a string> if tag == 4: pka = <a string> print pka # (1) print pka # (2) <do stuff not modifying pka> print pka # (3) if pka == 'RSA': <do stuff> elif pka == 'DSA': <do stuff> my code will error at (2). however, it will print out (1), (2), and (3), all of which are the same. is there any general explanation of why this is happening? if my code is really needed, i will post it, but otherwise, i would rather not due to its size update: now the code will error at the if statement after (3), saying UnboundLocalError: local variable 'pka' referenced before assignment even though (1),(2),(3) just printed

  • Interacting with Sql Server jobs programmatically

    - by Shlomo
    I would like to be able to interact with a Sql Server job programmatically through a web page. What is the best way to do this? Through SMO? The job will take a long time to run, so it needs to fire and forget, and I would also like to be able to stop it. If SMO, can anybody point me to an easy tutorial? Google gave me some fairly basic stuff but nothing substantial... SQL Server 2008, ASP.NET MVC web app.

  • Key logger wont record key strokes without console

    - by Daniel Gopar
    I created a small basic key logger in C++. For some reason when I compile and run the program with the console displayed, it will record every key stroke I make in whatever program I am using such as a browser and store it in a text file. However when I make it so that it WON'T display a console window, it will not record anything and it's just a process in the background doing nothing. Here is the link to my code: http://pastebin.com/4wqQyLJ9 The function that is giving me trouble with hiding the console, is the Stealth() function. Any suggestions, tips or hints will be helpful. Thanks.

  • Send data to webserver from C#, what's the most efficient way?

    - by Brian
    I am sending gps coordinates from a windows mobile phone to a webserver using a basic program I wrote in C#. The problem is the data plan on the phone only allows 4 MB per month. I was planning on updating the location every 10 seconds. Currently I am just creating a webrequest every 10 seconds to a php page on the server and the coordinates are passed over in the url, the php page saves them to the database. This generates about 1K of data per request, at this rate I will hit my data limit in less than a day. Is there a more efficient way to do this?

  • How to convert "9:00 PM EST" to a Date object

    - by Bara
    I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST" How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00" How would I change it to instead be: "4/24/10 09:00:00 EST" I would prefer to do this without the use of an external library, if possible.

  • Help regarding no sql databases like hadoop, hbase etc

    - by user560370
    I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

  • best way to build iphone settings screen

    - by Christian Schlensker
    I'm building a settings screen for an iPhone app and it is supposed to resemble a grouped table view. Each "cell" should behave like a button. Most cells just have a image view, label view, and disclosure indicator. One will display a value in addition to a label. All of these buttons will present a new view when tapped. Now, how to implement this? I was considering just laying out a set of buttons with custom background images, or would it be best to just use a table view. If that's the case what should it be implemented. So far I've only used table views to display some kind of dynamic data in which each cell displayed the same basic detail view. I'm most curious to figure out how to setup cellForRowAtIndexPath. Would this contain some sort of switch statement to configure each cell individually, or is there an easier way to handle all this?
