  • How to arrange models, views, controllers in a Kohana 3 project

    - by Pekka
    I'm looking at how to set up a mid-sized web application with Kohana 3. I have implemented MVC patterns in the past but never worked against a "formalized" MVC framework so I'm still getting my head around the terminology - toying around with basic examples, building views and templates, and so on. I'm progressing fairly well but I want to set up a real-world web project (one of my own that I've been planning for quite some time now) as a learning object. I learn best by example, but example-based documentation is a bit sparse for Kohana 3 right now - they say so themselves on the site. While I'm not worried about getting into the framework soon enough, I'm a bit concerned about arranging a healthily structured code base from the start - i.e. how to split up controllers, how to name them, and how to separate the functionality into the appropriate models. My application could, in its core, be described as a business directory with a main businesses table. Businesses can be listed by category and by street name. Each business has a detail page. Business owners can log in and edit their business's entry. Businesses can post offers into an offers table. I know this is not very detailed, but I don't want to cram too much information into this question. I'll be more than happy to go into more detail if needed. Supposing I have all the basic functionality worked out and in place already - list all businesses, edit business, list businesses by street name, create offer logged in as business, and so on, and I'm just looking for how to fit the functionality into a MVC pattern and into a Kohana application structure that can be easily extended: Do you know real-life, publicly accessible examples of "database-heavy" applications like directories, online communities... with a log-in area built on Kohana 3 where I could take a peek how they do it? Are there conventions or best practices on how to structure an extendable login area for end users in a Kohana project that is not only able to handle a business directory page, but further products on separate pages as well? Do you know application structuring HOWTOs or best practices for Kohana 3 not mentioned in the user guide and the inofficial Wiki? Have you built something similar and could give me some recommendations?

  • DataMapper Dates

    - by Ethan Turkeltaub
    Forgive me if this is a simple answer. But how do you get a Date from a DataMapper property. For example: require 'rubygems' require 'sinatra' require 'datamapper' class Test include DataMapper::Resource property :id, Serial property :created_at, Date end get '/:id' do test = Test.get(1) test.created_at = ? end

  • Does EF 4 Code First's ContextBuilder Dispose its SqlConnection?

    - by Eric J.
    Looking at Code First in ADO.Net EF 4 CTP 3 and wondered how the SqlConnection in their walkthrough is disposed. Is that the responsibility of ContextBuilder? Is it missing from the example? var connection = new SqlConnection(DB_CONN); var builder = new ContextBuilder<BloggingModel>(); var connection = new SqlConnection(DB_CONN); using (var ctx = builder.Create(connection)) { //... }

  • How to undo fill-paragraph in emacs?

    - by Dave Paroulek
    I have a text file that is pretty long. Any easy way to "undo" a M-q (fill-paragraph) on a file that was written and saved a while ago? For example, I want to change this: They're coming to take me away, ha-haaa!! They're coming to take me away, ho-ho, hee-hee, ha-haaa To this: They're coming to take me away, ha-haaa!! They're coming to take me away, ho-ho, hee-hee, ha-haaa

  • Asynchronous callback for network in Objective-C Iphone

    - by vodkhang
    I am working with network request - response in Objective-C. There is something with asynchronous model that I don't understand. In summary, I have a view that will show my statuses from 2 social networks: Twitter and Facebook. When I clicked refresh, it will call a model manager. That model manager will call 2 service helpers to request for latest items. When 2 service helpers receive data, it will pass back to model manager and this model will add all data into a sorted array. What I don't understand here is that : when response from social networks come back, how many threads will handle the response. From my understanding about multithreading and networking (in Java), there must have 2 threads handle 2 responses and those 2 threads will execute the code to add the responses to the array. So, it can have race condition and the program can go wrong right? Is it the correct working model of iphone objective-C? Or they do it in a different way that it will never have race condition and we don't have to care about locking, synchronize? Here is my example code: ModelManager.m - (void)updateMyItems:(NSArray *)items { self.helpers = [self authenticatedHelpersForAction:NCHelperActionGetMyItems]; for (id<NCHelper> helper in self.helpers) { [helper updateMyItems:items]; // NETWORK request here } } - (void)helper:(id <NCHelper>)helper didReturnItems:(NSArray *)items { [self helperDidFinishGettingMyItems:items callback:@selector(model:didGetMyItems:)]; break; } } // some private attributes int *_currentSocialNetworkItemsCount = 0; // to count the number of items of a social network - (void)helperDidFinishGettingMyItems:(NSArray *)items { for (Item *item in items) { _currentSocialNetworkItemsCount ++; } NSLog(@"count: %d", _currentSocialNetworkItemsCount); _currentSocialNetworkItemsCount = 0; } I want to ask if there is a case that the method helperDidFinishGettingMyItems is called concurrently. That means, for example, faceboook returns 10 items, twitter returns 10 items, will the output of count will ever be larger than 10? And if there is only one single thread, how can the thread finishes parsing 1 response and jump to the other response because, IMO, thread is only executed sequently, block of code by block of code

  • Google Visualization API chart in Blogger / Blogspot

    - by gotgenes
    Is it possible to embed (chart) visualizations created by the Google Visualization API in a Blogger post? I tried stripping out the <head> and <body> tags (and closing tags) from the pie chart example, however, the pie chart visualization fails to render, even on a published post. NOTE: I'm asking about the Visualization API, rather than the Google Image Charts (Charts API).

  • Run Google-apps-script on Google-Spreadsheet event?

    - by jdk
    If I create a Google apps script, can I hook it up to Google spreadsheet to run based on an event, or must I manually invoke it? I don't know if Google spreadsheet supports any events. For example: a Google app script that strikes out rows in the spreadsheet that have been marked completed by way of a column having the digit 1 beside completed rows. I would like this to run whenever a row is modified, or even when the spreadsheet is first loaded.

  • Injecting generics with Guice

    - by paradigmatic
    I am trying to migrate a small project, replacing some factories with Guice (it is my first Guice trial). However, I am stuck when trying to inject generics. I managed to extract a small toy example with two classes and a module: import com.google.inject.Inject; public class Console<T> { private final StringOutput<T> out; @Inject public Console(StringOutput<T> out) { this.out = out; } public void print(T t) { System.out.println(out.converter(t)); } } public class StringOutput<T> { public String converter(T t) { return t.toString(); } } import com.google.inject.AbstractModule; import com.google.inject.Guice; import com.google.inject.Injector; import com.google.inject.TypeLiteral; public class MyModule extends AbstractModule { @Override protected void configure() { bind(StringOutput.class); bind(Console.class); } public static void main(String[] args) { Injector injector = Guice.createInjector( new MyModule() ); StringOutput<Integer> out = injector.getInstance(StringOutput.class); System.out.println( out.converter(12) ); Console<Double> cons = injector.getInstance(Console.class); cons.print(123.0); } } When I run this example, all I got is: Exception in thread "main" com.google.inject.CreationException: Guice creation errors: 1) playground.StringOutput<T> cannot be used as a key; It is not fully specified. at playground.MyModule.configure(MyModule.java:15) 1 error at com.google.inject.internal.Errors.throwCreationExceptionIfErrorsExist(Errors.java:354) at com.google.inject.InjectorBuilder.initializeStatically(InjectorBuilder.java:152) at com.google.inject.InjectorBuilder.build(InjectorBuilder.java:105) at com.google.inject.Guice.createInjector(Guice.java:92) I tried looking for the error message, but without finding any useful hints. Further on the Guice FAQ I stumble upon a question about how to inject generics. I tried to add the following binding in the configure method: bind(new TypeLiteral<StringOutput<Double>>() {}).toInstance(new StringOutput<Double>()); But without success (same error message). Can someone explain me the error message and provide me some tips ? Thanks.

  • WPF ListView groups repeat column headers

    - by Riko
    Is there a way to repeat the column headers inside each group of a ListView.GridView when using a grouped CollectionViewSource as the source of the ListView? I am using the example at http://msdn.microsoft.com/en-us/library/ms754027.aspx which uses an Expander control to display each group. I would like the column headers to appear inside the expander for each group instead of at the top of the ListView.

  • How to use the callback method with a c++ directshow sample grabber

    - by Mr Bell
    I have a sample grabber hooked into my directshow graph, based on this example http://msdn.microsoft.com/en-us/library/dd407288(VS.85).aspx the problem is that it uses one shot and buffers. I want to continuously grab samples, and i'd rather have a callback than i guess polling for the samples. How do use the SetCallback method? SetCallback(ISampleGrabberCB *pCallback, long WhichMethodToCallback) how do I point pCallback to my own method?

  • Making a rails inflection for possessive strings?

    - by chovy
    I would like to create a method in additional to the default 'foo'.titlecase that will correctly add "possessiveness" to it. The string is a user's name (<- just did one right there! ) For example: "sam" is the user <%= user.titlecase.possessive + ' Profile' % = #Sam's Profile It just needs to handle edge cases like: Steelers's Profile ( should be Steelers' Profile) Ross's Profile ( should be Ross' Profile )

  • Using the apostrophe for PHP associative array element's name

    - by Haskella
    Hi I've been trying to figure out how to put something like Joe's Fruits into a PHP array something like this: <?php $arr = array( 'Fruitland' => '3ddlskdf3', 'Joe's Fruits' => 'dddfdfer3', ); ?> Using the above for example (stackoverflow's code color should tell you this by now), the array will take it as 'Joe' between the two apostrophes instead of the whole 'Joe's Fruits' is there any way I can do this without just calling it 'Joes Fruits'?

  • OSX, G/AWK, Bash - "illegal statement"

    - by S1syphus
    I have a script that somebody from SO kindly provided to solve an issue I was having, However, I'm having some issues getting it to work on OSX. gawk --version GNU Awk 3.1.6 awk --version awk version 20100208 The original source is: awk -F, -vOFS=, -vc=1 ' NR == 1 { for (i=1; i<NF; i++) { if ($i != "") { g[c]=i; f[c++]=$i } } } NR>2 { for (i=1; i < c; i++) { print $1,$2, $g[i] > "output_"f[i]".csv } }' data.csv When I run the script it gives the following error: awk: syntax error at source line 12 context is print $1,$2, $g[i] > >>> "output_"f <<< [i]".csv awk: illegal statement at source line 13 From the look of it the variable of [i] isn't been amended to the output file, but I don't know why. If I change AWK to GAWK and run the original script here is the output: gawk: cmd. line:11: print $1,$2, $g[i] > "output_"f[i]".csv gawk: cmd. line:11: ^ unterminated string So I edit the relevant line to fix the unterminated string print $1,$2, $g[i] > "output_"f[i]".csv" Then it runs through fine produces no errors, but there is no output files. Any ideas? I spent the majority of last night and this morning pouring over this.
