  • Really basic Django E-commerce? Where do I start

    - by Andrew
    I'm trying to set up a really basic e-commerce site with Django, and am trying to figure out the best place to start. I am relatively comfortable with the framework itself, but have never done any sort of e-commerce development in any language, so I want to learn about some best practices so I don't make any huge or obvious mistakes. I've looked at Satchmo, and even went as far as installing and playing around with it, but it looks like way more than I want. I basically want to show users a list of things, and let them click a button to buy one. No cart, no shipping, just click a button, connect with Authorize.net (or something similar) to do the transaction, and then display a confirmation page. Any suggestions or online tutorials people have found helpful? Even perhaps a tutorial in another language. Or maybe a really lightweight Django plugin that doesn't try to do everything like Satchmo? I've been coming up with very little so far. Thanks!

  • sharpsvn search repository commits

    - by Andrew Day
    Using sharpsvn I want to search all of the comments on the commited files in our svn server for specific strings. but i cannot get this to work. I have tried the following but it does not like my target path. Error: Revision type requires a working copy path, not a URL SvnRevisionRange range = new SvnRevisionRange(SvnRevision.Working, SvnRevision.Zero); string targetPath = "http://********:81/svn/"; Collection<SvnLogEventArgs> items; SvnLogArgs args = new SvnLogArgs { Range = range }; client.GetLog(new Uri(targetPath), args, out items); any ideas would be great

  • Why can't you return a List from a Compiled Query?

    - by Andrew
    I was speeding up my app by using compiled queries for queries which were getting hit over and over. I tried to implement it like this: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id) End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, List(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ (From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u).ToList()) This did not work and I got this error message: Type : System.ArgumentNullException, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Value cannot be null. Parameter name: value However, when I changed my compiled query to return IQueryable instead of List like so: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id).ToList() End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, IQueryable(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u) It worked fine. Can anyone shed any light as to why this is? BTW, compiled queries rock! They sped up my app by a factor of 2.

  • Why is an anonymous inner class containing nothing generated from this code?

    - by Andrew Westberg
    When run through javac on the cmd line Sun JVM 1.6.0_20, this code produces 6 .class files OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When run through JDT in eclipse, it produces only 5 classes. OuterClass.class OuterClass$1.class OuterClass$InnerClass.class OuterClass$InnerClass2.class OuterClass$InnerClass$InnerInnerClass.class OuterClass$PrivateInnerClass.class When decompiled, OuterClass$1.class contains nothing. Where is this extra class coming from and why is it created? package com.test; public class OuterClass { public class InnerClass { public class InnerInnerClass { } } public class InnerClass2 { } //this class should not exist in OuterClass after dummifying private class PrivateInnerClass { private String getString() { return "hello PrivateInnerClass"; } } public String getStringFromPrivateInner() { return new PrivateInnerClass().getString(); } }

  • Integration tests - "no exceptions are thrown" approach. Does it make sense?

    - by Andrew Florko
    Sometimes integration tests are rather complex to write or developers have no enough time to check output - does it make sense to write tests that make sure "no exceptions are thrown" only? Such tests provide some input parameters set(s) and doesn't check the result, but only make sure code not failed with exception? May be such tests are not very useful but appropriate in situations when you have no time?

  • How do you populate a NSArrayController with CoreData rows programmatically?

    - by Andrew McCloud
    After several hours/days of searching and diving into example projects i've concluded that I need to just ask. If I bind the assetsView (IKImageBrowserView) directly to an IB instance of NSArrayController everything works just fine. - (void) awakeFromNib { library = [[NSArrayController alloc] init]; [library setManagedObjectContext:[[NSApp delegate] managedObjectContext]]; [library setEntityName:@"Asset"]; NSLog(@"%@", [library arrangedObjects]); NSLog(@"%@", [library content]); [assetsView setDataSource:library]; [assetsView reloadData]; } Both NSLogs are empty. I know i'm missing something... I just don't know what. The goal is to eventually allow multiple instances of this view's "library" filtered programmatically with a predicate. For now i'm just trying to have it display all of the rows for the "Asset" entity. Addition: If I create the NSArrayController in IB and then try to log [library arrangedObjects] or manually set the data source for assetsView I get the same empty results. Like I said earlier, if I bind library.arrangedObjects to assetsView.content (IKImageBrowserView) in IB - with same managed object context and same entity name set by IB - everything works as expected. - (void) awakeFromNib { // library = [[NSArrayController alloc] init]; // [library setManagedObjectContext:[[NSApp delegate] managedObjectContext]]; // [library setEntityName:@"Asset"]; NSLog(@"%@", [library arrangedObjects]); NSLog(@"%@", [library content]); [assetsView setDataSource:library]; [assetsView reloadData]; }

  • Setting many key/value pairs

    - by Andrew
    Hi, I'm working on a rake task which imports from a JSON feed into an ActiveRecord called Person. Person has quite a few attributes and rather than write lines of code for setting each attribute I'm trying different methods. The closest I've got is shown below. This works nicely as far as outputing to screen but when I check the values have actually been set on the ActiveRecord itself it's always nil. So it looks like I can't use .to_sym to solve my problem? Any suggestions? I should also mention that I'm just starting out with Ruby, have been doing quite a bit of Objective-c and now need to embrace the Interwebs :) http = Net::HTTP.new(url.host, url.port) http.read_timeout = 30 json = http.get(url.to_s).body parsed = JSON.parse(json) if parsed.has_key? 'code' updatePerson = Person.find_or_initialize_by_code(parsed['code']) puts updatePerson.code parsed.each do |key, value| puts "#{key} is #{value}" symkey = key.to_sym updatePerson[:symkey] = value.to_s updatePerson.save puts "#{key}....." # shows the current key puts updatePerson[:symkey] # shows the correct value puts updatePerson.first_name # a sample key, it's returning nil end

  • getting userbase vote average and individual user's vote in the same query?

    - by Andrew Heath
    Here goes: T1 [id] [desc] 1 lovely 2 ugly 3 slender T2 [id] [userid] [vote] 1 1 3 1 2 5 1 3 2 2 1 1 2 2 4 2 3 4 In one query (if possible) I'd like to return: T1.id, T1.desc, AVG(T2.vote), T2.vote (for user viewing the page) I can get the first 3 items with: SELECT T1.id, T1.desc, AVG(T2.vote) FROM T1 LEFT JOIN T2 ON T1.id=T2.id GROUP BY T1.id and I can get the first, second, and fourth items with: SELECT T1.id, T1.desc, T2.vote FROM T1 LEFT JOIN T2 ON T1.id=T2.id WHERE T2.userid='1' GROUP BY T1.id but I'm at a loss as to how to get all four items in one query. I tried inserting a select as the fourth term: SELECT T1.id, T1.desc, AVG(T2.vote), (SELECT T2.vote FROM T2 WHERE T2.userid='1') AS userVote etc etc but I get an error that the select returns more than one row... Help? My reason for wanting to do this in one query instead of two is that I want to be able to sort the data within MySQL rather than one it's been split into a number of arrays.

  • Logging a certain event only once in ruby

    - by Andrew Grimm
    Are there any logging frameworks in ruby that allow you to log a specific event type only once? logger = IdealLogger.new logger.log(:happy_path, "We reached the happy path") # => logs this message logger.log(:happy_path, "We reached the happy path yet again") # => Doesn't log this logger.log(:sad_path, "We've encountered a sad path!") # => logs this message Also, is there a term for the concept of logging a certain event type only once?

  • How do I programmatically run all the JUnit tests in my Java application?

    - by Andrew McKinlay
    From Eclipse I can easily run all the JUnit tests in my application. I would like to be able to run the tests on target systems from the application jar, without Eclipse (or Ant or Maven or any other development tool). I can see how to run a specific test or suite from the command line. I could manually create a suite listing all the tests in my application, but that seems error prone - I'm sure at some point I'll create a test and forget to add it to the suite. The Eclipse JUnit plugin has a wizard to create a test suite, but for some reason it doesn't "see" my test classes. It may be looking for JUnit 3 tests, not JUnit 4 annotated tests. I could write a tool that would automatically create the suite by scanning the source files. Or I could write code so the application would scan it's own jar file for tests (either by naming convention or by looking for the @Test annotation). It seems like there should be an easier way. What am I missing?

  • MySQL: Question about SELECT WHERE AND/OR

    - by Andrew
    I'm trying to write a query that returns the same result from three different events, but I think I am doing it wrong. I can run my query against one event ID and it works. How can I select all three? Here's what I have so far: SELECT * FROM `Registrations` WHERE `Role` = "Attendee" AND `RegistrationStatus_ID` = "1" AND `DigSignature` IS NULL AND `Event_ID` = "147" OR `Event_ID` = "155" OR `Event_ID` = "160"

  • How to Inserting message into View that depends on session value. ASP.NET MVC. Best practice

    - by Andrew Florko
    User have to populate multistep questionnaire web-forms and step messages depend on the option chosen by user at the very beginning. Messages are stored in web.config file. I use asp.net mvc project, strong typed views and keep business logic separated from controller in static class. I don't want to make business logic dependency on web.config. Well, I have to insert message into view that depends on session value. There are at least 2 options how to implement this: View model has property that is populated in controller/businessLogic and rendered in view like <%: Model.HelpMessage1 %>. I have to pass web.config values from controller to businessLogic that makes business logic methods signature too complex. I don't want to make configuration source abstract (in order to let business logic read configuration values from its methods directly) also. Create static helper class that is called from view like <%: ViewHelper.HelpMessage1(Model.Option1) %>. But in this case logic what to show seems to be separated into two classes: business logic & viewHelper. What will you suggest? Thank you in advance!

  • How do you remove functionality from a program in ruby?

    - by Andrew Grimm
    You have some code you want to remove associated with an obsolete piece of functionality from a ruby project. How do ensure that you get rid of all of the code? Some guidelines that usually help in refactoring ruby apply, but there are added challenges because having code that isn't being called by anything won't break any unit tests.

I don't want to loose any fancy ajax feature but I also need to keep the website on the google map :) thank you in advance for any answer ! btw the website is developed in asp.net c# .

  • Windows Forms application C# | Sending Tweet

    - by Andrew Craswell
    I've been able to get my Twitter web app working just fine, but I've recently decided to add Tweeting functionality from a Windows Form, but I'm having no luck sending tweets. No errors are thrown or anything. Mind looking over my code? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using TweetSharp; namespace TwitterAdvirtiser { public partial class Form1 : Form { private string cKey = "xxx"; private string cSecret = "xxx"; private string oToken = "xxx"; private string aToken = "xxx"; public Form1() { InitializeComponent(); OnStart(); } private void OnStart() { //Authenticate with Twitter TwitterService service = new TwitterService(cKey, cSecret); service.AuthenticateWith(oToken, aToken); service.SendTweet("testing"); } } } It seems like I'm authenticating just fine, I can walk through debug mode and see all my details in the TwitterUser structure, and yet my tweets never show up on my feed. Whats up? By the way, I'm using Visual Studios 2010, and .NET 4.0. I have verified that the oToken and aToken strings have my developer tokens.

  • Organizing PHP includes in your development environment

    - by Andrew Heath
    I'm auditing my site design based on the excellent Essential PHP Security by Chris Shiflett. One of the recommendations I'd like to adopt is moving all possible files out of webroot, this includes includes. Doing so on my shared host is simple enough, but I'm wondering how people handle this on their development testbeds? Currently I've got an XAMPP installation configured so that localhost/mysite/ matches up with D:\mysite\ in which includes are stored at D:\mysite\includes\ In order to keep include paths accurate, I'm guess I need to replicate the server's path on my local disk? Something like D:\mysite\public_html\ Is there a better way?

  • Embed Git Commit Log in Rails App?

    - by Andrew
    So, I have a 'development blog' in a rails app I'm working on right now. I'm using Git for version control and deployment (although right now I'm the only person working on it). Now, when I make changes in Git I put a pretty decent log entry about what I've done. I'd love to have the Git commit log automatically posted to the development blog -- or otherwise available for others to read within the deployed site. Is there an automated way to pull the Git Commit Log into a view in a rails app?

  • "'Objects' may not respond to 'functions'" warnings.

    - by Andrew
    Hello all, for the last couple of weeks I've finally gotten into Obj-C from regular C and have started my first app. I've watched tutorials and read through a book along with a lot of webpages, but I know I've only just begun. Anyway, for most of the night and this morning, I've been trying to get this code to work, and now that it will compile, I have a few warnings. I've searched and found similar problems with solutions, but still no dice. What I'm trying to do is put an array made from a txt document into the popup list in a combo box. AwesomeBoxList.h: #import <Cocoa/Cocoa.h> @interface AwesomeBoxList : NSObject { IBOutlet NSComboBox *ComboBoz; } -(NSArray *) getStringzFromTxtz; - (void) awesomeBoxList; @end AwesomeBoxList.m: #import "AwesomeBoxList.h" @implementation AwesomeBoxList -(NSArray *)getStringzFromTxtz { ... return combind; } - (void) awesomeBoxList { [ComboBoz setUsesDataSource:YES]; [ComboBoz setDataSource: [ComboBoz getStringzFromTxtz]: //'NSComboBox' may not respond to 'getStringzFromTxtz' [ComboBoz comboBox:(NSComboBox *)ComboBoz objectValueForItemAtIndex: [ComboBoz numberOfItemsInComboBox:(NSComboBox *)ComboBoz]]]; /*'NSComboBox' may not respond to '-numberOfItemsInComboBox:' 'NSComboBox' may not respond to '-comboBox:objectValueForItemAtIndex:' 'NSComboBox' may not respond to '-setDataSource:' */ } @end So, with all of these errors and my still shallow knowledge of Obj-C, I must be making some sort of n00b mistake. Thanks for the help.

  • Finding an asp:button and asp:textbox in Javascript

    - by Andrew
    What I'm trying to do is get an asp:button to click. The only problem is that it is within a few tags. Example: <loginview> <asp:login1> <logintemplate> //asp:textbox and asp:button are located here. </loginview> </asp:login> </logintemplate> So how would I get javascript to point to that location so that I can manipulate it. For example, get the button to click.

  • Flash Displaying Weird Text in a Dynamic Text Field

    - by Andrew M
    I am working in Flash CS5 and I have placed a text field (dynamic, classic text) on the stage. I am accessing it through Actionscript on the same frame like this: var ct:TextField = TextField(getChildByName("Temperature")); ct.text = "Hello world"; What ACTUALLY appears is this: eo wor So... The H, Ls, and D are gone. Mysteriously. Without warning. I am sitting here utterly confused. Is this just me? PS. The text field is set to Myriad Pro Bold, a font on my computer, so it isn't like it's a font problem.

  • When can argv[0] have null ?

    - by andrew-dufresne
    What I have understand about passing arguments to main() from command line is that argc has a minimum value of 1 and argv[0] will always have the program name with its path in it. If arguments are provided at the command line, then argc will have a value greater than one and argv1 to argv[argc-1] will have those arguments. Now a paragraph at this link says that argv[0] will be a string containing the program's name or a null string if that is not available. Now, how and when can argv[0] have null string? I mean program name with its path will always be available so when can it be null? Writer says that "if that is not available" but when and how it is possible that program name will not be available? Thanks for your time and support. Regards
