Is it possible to do static methods in modules as in Ruby ?
module Test
self.def test
puts "test"
end
end
Test::test
I get a expecting token 'EOF', not 'end' if the call is in the same file ( as shown in the exemple ) and a expecting token 'CONST', not 'test' if I place the call in a different file.
What am I doig wrong ? Is there static methods in modules in Crystal ?
The correct syntax for class methods is def self.test, not self.def test. Class methods are called using Test.test, not Test::test.

I'm trying to call static function of module named: Mymodule from another module like this: Mymodule::doThis()
But got error:
Fatal error: Class 'Mymodule' not found
I know, I can use code:
include_once _PS_MODULE_DIR_.'mymodule/mymodule.php',
but I want to know if I can use class autoloading or other elegant way to achieve this
You can try this :
Mymodule::getInstanceByName('doThis');

I've defined an unordered group and it works like I expected. The only thing I would like to change is the error msg, which appears when an element of an unordered group isn't modelled yet. Is there an easy way to solve this? I tried already custom checks, but there I got an unexpected behaviour.
Following my rule for the unordered group and the error msg:
Element:
(name=ConfigurationName) &
(description=Description)? &
(tool=Tool) &
(model=Model) &
(interfaces=Interfaces)? &
(paramaters=Parameters)? &
(paramfile=ParamFile)?
;
rule ruleElement failed predicate: {getUnorderedGroupHelper().canLeave(grammarAccess.getElementAccess().getUnorderedGroup())}?
I want to change this error msg to something like: "The following elements are required in the configuration:...."
Xtext has a service called SyntaxErrorMessageProvider that is used to reword parser error messages. You have to define your messages on the parser level (so there will be no EMF model to use), but it is possible to get the original error message and the context, traverse it and provide your own error message.
To register this, open the «YourLanguage»RuntimeModule class, and add the following method:
public Class<? extends ISyntaxErrorMessageProvider> bindISyntaxErrorMessageProvider() {
return «YourLanguage»SyntaxErrorMessageProvider.class;
}
where «YourLanguage«SyntaxErrorMessageProvider is a class introduced by you, extending the class SyntaxErrorMessageProvider, where you can implement your custom function.
I works Automatic Validation customize,I create
public class MyDslLanguageSyntaxErrorMessageProvider extends SyntaxErrorMessageProvider {
}
And I Register it in the MyDslRuntimeModule:
public Class bindISyntaxErrorMessageProvider() {
return MyDslLanguageSyntaxErrorMessageProvider.class;}
But my problem is which package is used for this customization.I used org.xtext.example.mydsl.validation package for create java class .Also I do this customization with xtend class.I do not find enough source in the internet :(
You can use Java to write this Custom SyntaxErrorMessageProvider class, but to bind this you can bind in Runtime Module class. Also u can use any package to declare this class but declaring this class in same package where u have Runtime class makes sense
I have a Test Case called "testCaseOne"
It contains three Test Steps:
"AMFrequestOne"
"propertyTransfer"
"AMFrequestTwo"
"AMFrequestOne" creates a database object.
"propertyTransfer" sends the ResponseAsXml to a temporary property in "testCaseOne" called "tempProp".
I need to reference "tempProp" in a script inside of "AMFrequestTwo"
I've tried the following
def temp = testRunner.testCase.getPropertyValue( "tempProp" )
but I get the error "No such property: testRunner for class: Script6" (number increments with tries)
Is this because in an AMF request "Script is invoked with log, context, parameters and amfHeaders variables" and testRunner is not recognized?
I know it seems odd, but is it possible to do this? I'm unable to use a specific xpath property transfer between the two AMF Requests as it's possible for the structure to change and I'm not always looking for the same node.
Used
def temp = context.testCase.getPropertyValue( "tempProp" )
instead of
def temp = testRunner.testCase.getPropertyValue( "tempProp" )
and this works fine.
After logged in successfully, Yii does not executing any page.
Showing an error:
Error 404 Unable to resolve the request "membersdet/index"
Here membersdet is controller Id and index is an action.
Make sure the filename of your controller is EXACTLY "MembersdetController.php". It is case sensitive.
I guess you were developing on local machine under Windows OS and server runs on *nix system. That's normal issue for novice developers, that they forget about case sensitive file system in *nix.
It is because of wrong controller file name given or may be actionIndex() method is not in your controller.
I have had a similar problem and got it solved. In this case the file was correctly named but the class name was wrongly spelled. When these two do not correspond, you could get this error too.
Check case sensitive exactly your controller: MembersdetController
Check alias (common in config/main.php) map with namespace in your controller
Yii::setAlias('#tienn2t', dirname(dirname(__DIR__)) . '/tienn2t');
In MembersdetController.php file
<?php
namespace tienn2t\controllers;
use Yii;
use yii\web\Controller;
class MembersdetController extends Controller{
public function actionIndex(){
echo 1;die;
}
}
There is not enough information in the question, but maybe you have an incorrect .htaccess or if you don't have an htaccess at all you should use the url:
http://host/index.php?r=membersdet/index
Make sure you have MembersdetController in /protected/controllers/ and this class "is a" CController and has a public method named actionIndex().
Check errorHandler block in your config file.
I had fix this error like this
'errorHandler' => [
'errorAction' => 'error/index',
],
By the way you should have appropriate ErrorController in your module and /error/index.php
file in view folder.
Hope will help you.
I'm writing a generator and I need to get mock a Rails.application object and get back the Rails.application.class.parent as the name of the Rails application.
def test_model_with_application_namespace
name = "Dummyapp"
application = Rails.stubs(:application).class.parent.returns(name)
run_generator ["file", "--namespaced"]
assert_file "app/models/myapp/file.rb", /class Dummyapp::File < ActiveRecord::Base/
end
This is what I have so far for my test.
You need the object retured by Rails.application.class to be a mock that responds to parent and returns name. Right now, you just stub out application. You need parent, class, and application to be mocks. There is probably a cleaner way of doing it, but I think this will do what you want:
application = Rails.stubs(:application).returns(mock(:class => mock(:parent => name)))
