I have been following the book provided by the agile toolkit and am at this portion:
http://agiletoolkit.org/learn/app/logic
Unfortunately the dsql api lacks some clarity and the calculated fields example on that page is just not working.
I tried using:
class Model_DVD extends Model_Table {
public $table='dvd';
function init(){
parent::init();
$this->hasOne('Movie');
$this->addField('code');
$this->addfield('is_rented')
->type('boolean')
->calculated(true);
}
function calculate_is_rented(){
return $this->add('Model_Rental')
->dsql()
->field('id')
->where('rental.dvd_id=dvd.id')
->where('is_returned!=','Y')
->select()
;
}
}
This returns 1 every time so I tried to follow:
Calculated field always returns 1 - atk 4.2
And now I'm not sure how to create this properly; I know the following works but I kind of made it up as I went and have NO IDEA why it works, and why I need the count() - etc etc.
How do I go about getting the calculated field to work? Can someone please explain it in this example, I learn best by examples so I wanted to follow through with it.
My working code that I don't understand:
class Model_DVD extends Model_Table {
public $table='dvd';
function init(){
parent::init();
$this->hasOne('Movie');
$this->addField('code');
$this->debug();
$this->addExpression('is_rented')->set($this->add('Model_Rental')
->addCondition('dvd_id', $this->_dsql()->getField('id'))
->count()
->where('is_returned!=','Y'))
->datatype('boolean')
->enum(array('Y', 'N'));
}
}
Thanks!

I am developing a mod_plugin for Moodle and want to support the automatic activity completion with a custom rule. I followed the official documentation and implemented all necessary functions. In the lib.php [pluginname]_supports method I have registered, FEATURE_GRADE_HAS_GRADE, FEATURE_COMPLETION_TRACKS_VIEWS, FEATURE_COMPLETION_HAS_RULES.
The \mod_[pluginname]\completion\custom_completion class defines a custom rule named "completiontest" in get_defined_custom_rules(). During my tests I found out that the methods get_state(), get_sort_order() and get_custom_rule_descriptions() are never executed. Also I don't see any output via activity_information().
I have cleared all caches, created new instances of my activity module, with no result. My development environment uses Moodle 3.11.7 (Build: 20220509).
My custom_completion.php script:
<?php
declare(strict_types=1);
namespace mod_cwr\completion;
use core_completion\activity_custom_completion;
class custom_completion extends activity_custom_completion {
public function get_state(string $rule): int {
return COMPLETION_INCOMPLETE;
}
public static function get_defined_custom_rules(): array {
return [
'completiontest'
];
}
public function get_custom_rule_descriptions(): array {
return [
'completiontest' => 'testout'
];
}
public function get_sort_order(): array {
return [
'completionview',
'completiontest',
'completionusegrade'
];
}
}
Test at the view.php:
$completion = new completion_info($course);
$completion->set_module_viewed($coursemodule);
if($completion->is_enabled($coursemodule) == COMPLETION_TRACKING_AUTOMATIC){
$completion->update_state($coursemodule, COMPLETION_INCOMPLETE, $USER->id);
}
$completiondetails = \core_completion\cm_completion_details::get_instance($coursemodule, $USER->id);
$activitydates = \core\activity_dates::get_dates_for_module($coursemodule, $USER->id);
echo $OUTPUT->activity_information($coursemodule, $completiondetails, $activitydates);
At the mod_form.php I check with completion_rule_enabled() if a custom rule is activated by the settings.
Does anyone have any idea what the problem could be?
Looking at the mod_forum plugin code showed me, that the get_state($rule) method does not observe all custom rules, only those selected in the settings. How do I tell Moodle to use a specific custom rule?
You appear to be calling update_state() and passing in the possible state change as COMPLETION_INCOMPLETE.
This is a way of telling Moodle "if the state is already incomplete, don't bother doing any expensive completion calculations to check if it should change state".
If you want Moodle to check and then (potentially) change the state to "complete", then pass COMPLETION_COMPLETE. If you really don't know which way it could be switching, then leave the param at the default COMPLETION_UNKNOWN (a good example would be forum completion - if you have just created a forum post, then you might cause the forum to be marked as "complete", but you certainly can't cause the forum to be marked as "incomplete", so you can pass the COMPLETION_COMPLETE parameter, so Moodle knows it only needs to check for changes if the forum is not already "complete").
Also, don't bother passing $USER->id as the third parameter - that's the default which is used of you don't pass anything.
As for telling Moodle which rules to use - it is up to you, when your function is called, to check your plugins settings to determine which rules are in use (and any other relevant configuration - e.g. with mod_forum, it needs to check how many posts are required for completion).
Thank you for the support. Got it running.
I now use $completion->update_state($coursemodule, COMPLETION_COMPLETE); and also had to fix [pluginname]_get_coursemodule_info() with $result->customdata['customcompletionrules']['completiontest'] = $cwr->completiontest; and totally forgot the return $result;.
I'm new at Apache Isis and I'm stuck.
I want to create my own submit form with editable parameters for search some entities and a grid with search results below.
Firstly, I created #DomainObject(nature=Nature.VIEW_MODEL) with search results collection, parameters for search and #Action for search.
After deeper research, I found out strict implementations for actions (For exapmle ActionParametersFormPanel). Can I use #Action and edit #DomainObject properties(my search parameters for action) without prompts?
Can I implement it by layout.xml?
Then I tried to change a component as described here: 6.2 Replacing page elements, but I was confused which ComponentType and IModel should I use, maybe ComponentType.PARAMETERS and ActionModel or implement my own IModel for my case.
Should I implement my own Wicket page for search and register it by PageClassList interface, as described here: 6.3 Custom pages
As I understood I need to replace page class for one of PageType, but which one should I change?
So, the question is how to implement such issues properly? Which way should I choose?
Thank you!
===================== UPDATE ===================
I've implemented HomePageViewModel in this way:
#DomainObject(
nature = Nature.VIEW_MODEL,
objectType = "homepage.HomePageViewModel"
)
#Setter #Getter
public class HomePageViewModel {
private String id;
private String type;
public TranslatableString title() {
return TranslatableString.tr("My custom search");
}
public List<SimpleObject> getObjects() {
return simpleObjectRepository.listAll();
}
#Action
public HomePageViewModel search(
#ParameterLayout(named = "Id")
String id,
#ParameterLayout(named = "Type")
String type
){
setId(id);
setType(type);
// finding objects by entered parameters is not implemented yet
return this;
}
#javax.inject.Inject
SimpleObjectRepository simpleObjectRepository;
}
And it works in this way:
I want to implement a built-in-ViewModel action with parameters without any dialog windows, smth like this:
1) Is it possible to create smth like ActionParametersFormPanel based on ComponentType.PARAMETERS and ActionModel and use this component as #Action in my ViewModel?
2) Or I should use, as you said, ComponentType.COLLECTION_CONTENTS? As I inderstand my search result grid and my search input panel will be like ONE my stub component?
Thank you.
We have a JIRA ticket in our JIRA to implement a filterable/searchable component, but it hasn't yet made it to the top of the list for implementation.
As an alternative, you could have a view model that provides the parameters you want to filter on as properties, with a table underneath. (I see you asked another question here on SO re properties on view models, so perhaps you are moving in that direction also... I've answered that question).
If you do want to have a stab at implementing that ticket, then the ComponentTYpe to use is COLLECTION_CONTENTS. If you take a look at the isisaddons, eg for excel or gmap3 then it might help get you started.
======= UPDATE TO ANSWER (based on update made to query) ==========
I have some good news for you. v1.15.0-SNAPSHOT, which should be released in the couple of weeks, has support for "inline prompts". You should find these give a user experience very similar to what you are after, with no further work needed on your part.
To try it out, check out the current trunk, and then load the simpleapp (in examples/application/simpleapp). You should see that editing properties and invoking actions uses the new inline prompt style.

I would like to use d to create a RESTful web application.
What are the most actively maintained and contributed projects that are worth considering? A short comparison of these web frameworks with pluses and minuses will be nice.
My search lead me to only one project, which seems like an excellent framework:
vibe.d
Are there other projects which are minimal in nature like sinatra?
I've heard good things about vibe.d http://vibed.org/
Though, I've never personally used it because I wrote my own libraries well before vibe came out.
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff
vibe is better documented, so you might be better off going there, but here's how my libraries work:
cgi.d is the base web interface (use -version=embedded_httpd when compiling to use its own web server instead of CGI if you want), and I offer some RESTy stuff in a separate file called web.d. It depends on cgi.d, dom.d, characterencodings.d, and sha.d. You might also want database.d and mysql.d for connecting to a mysql database.
The way web.d works is you just write functions and it automatically maps them to url and formats data.
http://arsdnet.net/cgi-bin/apidemo/add-some-numbers
The source code to that portion is:
import arsd.web;
class MySite : ApiProvider {
export int addSomeNumbers(int a, int b) { return a+b; }
}
mixin FancyMain!MySite;
web.d automatically generates the form you see there, parses the url into the types given, and formats the return value into either html, json, or sometimes other things (for example, objects can be made into tables).
There is also an envelopeFormat url param that can wrap it in more json, best for machine consumption:
http://arsdnet.net/cgi-bin/apidemo/add-some-numbers?a=1&b=2&format=json&envelopeFormat=json
web.d.php in my github shows one way you can consume it, and web.d itself automatically generates javascript functions to call from the client:
MySite.addSomeNumbers(10, 20).get(function(answer) { alert("Server replied: " + answer); });
answer would be of the type returned by the D function.
If you don't want/need the automatic function wrapping, cgi.d alone gives access to the basic info and writing functions:
void requestHandler(Cgi cgi) {
// there's cgi.get["name"], cgi.post["name"], or cgi.request("name"), kinda like php
cgi.write("hello ", cgi.request("name"));
}
mixin GenericMain!requestHandler;
But yeah, most the documentation that exists for my library is just me talking about it on forums... I think once you've done one function it isn't hard to figure out, but I'm biased!
edit: copy/paste from my comment below since it is pretty relevant to really getting RESTy:
I actually did play with the idea of having urls map to objects and the verbs go through: web.d also includes an ApiObject class which goes: /obj/name -> new Obj("name"); and then calls the appropriate methods on it. So GET /obj/name calls (new Obj("name")).GET();, same for POST, PUT, etc. Then /obj/name/foo calls (new Obj("name").foo(); with the same rules as I described for functions above.
But I don't use it as much as the plain functions for one because it is still somewhat buggy.... and it is still somewhat buggy because I don't use it enough to sit down and fit it all! lol
You use it by writing an ApiObject class and then aliasing it into the ApiProvider:
import arsd.web;
class MySite : ApiProvider {
export int addSomeNumbers(int a, int b) { return a+b; }
alias MyObject obj; // new, brings in MyObject as /obj/xxx/
}
And, of course, define the object:
class MyObject : ApiObject {
CoolApi parent;
string identifier;
this(CoolApi parent, string identifier) {
this.parent = parent;
this.identifier = identifier;
/* you might also want to load any existing object from a database or something here, using the identifier string, and initialize other members */
// for now to show the example, we'll just initialize data with dummy info
data.id = 8;
data.name = "MyObject/" ~ identifier;
}
/* define some members as a child struct so we can return them later */
struct Data {
int id;
string name;
Element makeHtmlElement() {
// for automatic formatting as html
auto div = Element.make("div");
import std.conv;
div.addChild("span", to!string(id)).addClass("id");
div.appendText(" ");
div.addChild("span", name).addClass("name");
return div;
}
}
Data data;
export Data GET() {
return data;
}
export Data POST(string name) {
parent.ensureGoodPost(); // CSRF token check
data.name = name;
// normally, you'd commit the changes to the database and redirect back to GET or something like that, but since we don't have a db we'll just return the modified object
return data;
}
// property accessors for the data, if you want
export int id() {
return data.id;
}
}
mixin FancyMain!MySite;
Then you can access it:
http://arsdnet.net/cgi-bin/apidemo2/obj/cool/
BTW the trailing slash is mandatory: this is one of the outstanding bugs I haven't gotten around to fixing yet. (The trailing slash code is more complicated than it should be, making this harder to fix that it might look.)
Anyway, you can see the object rendered itself as html via makeHtmlElement. This is a good time to showcase other formats:
http://arsdnet.net/cgi-bin/apidemo2/obj/cool/?format=table
table, also try csv, and of course, json
http://arsdnet.net/cgi-bin/apidemo2/obj/cool/?format=json
or for machine consumption:
http://arsdnet.net/cgi-bin/apidemo2/obj/cool/?format=json&envelopeFormat=json
and the property is available too:
http://arsdnet.net/cgi-bin/apidemo2/obj/cool/id
Another major outstanding bug is that the automatically generated Javascript functions can't access child objects at all. They only work on functions on the top level ApiProvider. Another bug that is harder to fix than it might seem, and I'm not particularly driven to do so because the top-level functions can do it all anyway. Of course, you could make the URLs yourself on the xmlhttprequest and access it that way.
Let's also demo POST by slapping together a quick form:
http://arsdnet.net/cgi-bin/apidemo2/poster
you can submit something and see the POST handler indeed reset the name. (BTW note the action has that trailing slash: without it, it silently redirects you! I really should fix that.)
Anyway, bugs notwithstanding, the core of it works and might be the closest thing to full blown REST D has right now.
At the moment of writing this text there is no framework for building true RESTful web services that I know of. However, you should be able to easily build one on top of vibe.d or Adam's web modules that he already mentioned above.
You can take a look at what I'm building. Still extremely alpha, but I'm attempting to build a Rails-like framework in D: http://jaredonline.github.io/action-pack/
I know this is a really late answer, but I figured someone might come by this one day, since it has been so long and a lot of changes has happened within the D community, especially towards web development.
With Diamond you can write RESTful web applications without hacking something together, since it supports it within the framework.
http://diamondmvc.org/docs/backend/#rest
You can try Hunt Framework.
routes setting
GET /user/{id} user.detail
app/UserController.d souce code:
module app.controller.UserController;
import hunt.framework;
class User
{
int id;
string name;
}
class UserController : Controller
{
mixin MakeController;
#Action
JsonResponse detail(int id)
{
auto user = new User;
user.id = id;
user.name = "test";
return new JsonResponse(user);
}
}

I've created an app using MVVMCross, the IOS and Android versions are working but when I tried to "port" to WP7 and I ran into the following problem:
throw methodAccessException.MvxWrap("Problem accessing object - most likely this is caused by an anonymous object being generated as Internal - please see http://stackoverflow.com/questions/8273399/anonymous-types-and-get-accessors-on-wp7-1");
As mentioned in the answer to my other question about this (on Android) you have to set an InternalsVisibleTo attribute in the AssemblyInfo.cs for WP7. So I did:
[assembly: InternalsVisibleTo("Cirrious.MvvmCross.WindowsPhone")]
But this doesn't make any difference. I use the following code to send two variables form my BeckhoffViewModel to my BeckhoffSensorViewModel.
BeckhoffViewModel:
public IMvxCommand BeckhoffSensor1
{
get
{
return new MvxRelayCommand(kvpSens1);
}
}
private void kvpSens1()
{
RequestNavigate<BeckhoffSensorViewModel>(new { VarType = "short", Variable = ".countertest" });
}
BeckhoffSensorViewModel:
public BeckhoffSensorViewModel(string VarType, string Variable)
{
_vartype = VarType;
_variable = Variable;
}
Anything I'm overlooking? I also looked at the other stackoverflow topic mentioned in the exception but couldn't really understand it.
The anonymous class will most definitely be created as internal by the compiler - which is why you need the line [assembly: InternalsVisibleTo("Cirrious.MvvmCross.WindowsPhone")]
Can you check that the AssemblyInfo.cs file definitely being linked into the project (and that this is the project containing the ViewModel/anonymous-class code)?
If that is the case, can you check the methodAccessException to see what the message is?
If that doesn't help, can you use a tool like Reflector to check the internalVisible attribute is actually present on the core/application assembly?
I noticed that the blog module for SS have hardcoded pieces of text - that I need to translate (in french). I found that the code is in /blog/templates/Includes/BlogSummary.ss but when I modify it, nothing changes on front-end...
I tried to run a /dev/build/?flush=all but nothing... still.
Any idea? Help would be much appreciated. Thanks in advance.
Have you set your locale? I recently set up a site in English & Spanish and used this setup.
// add similar code to your _config.php file
#Translatable::set_default_locale('en_US');
#Translatable::set_allowed_locales(array(
# 'en_US',
# 'es_US'
#));
Further, I had to add i18n::set_locale() code to the init() function in my content controller to get the template translations to work.
<?php
class SmartLanguageExtension extends DataObjectDecorator {
function contentcontrollerInit() {
i18n::set_locale(Translatable::get_current_locale());
}
}
In my case, I added an extension to the Page_Controller class for reusability later on.
// _config.php file
Object::add_extension('Page', 'SmartLanguageExtension');
