Using the Symfony 1.4 framework, is it possible to take a template from the lib/mail directory and use it as a template within an action? I don't think using setTemplate will be possible for this, as this is the native method:
public function setTemplate($name, $module = null)
{
if (sfConfig::get('sf_logging_enabled'))
{
$this->dispatcher->notify(new sfEvent($this, 'application.log', array(sprintf('Change template to "%s/%s"', null === $module ? 'CURRENT' : $module, $name))));
}
if (null !== $module)
{
$name = sfConfig::get('sf_app_dir').'/modules/'.$module.'/templates/'.$name;
}
sfConfig::set('symfony.view.'.$this->getModuleName().'_'.$this->getActionName().'_template', $name);
}
If you want to use the templates in more projects you could make a plugin for that, or just symlink the module/template folder.
If you use the symlink, you can still use the setTemplate() function and all template will always be the same on every project.
Or you could rewrite the setTemplate() function, to accept a third argument and read the file from the sf_lib_dir instead of the sf_app_dir

Is there any documentation regarding how to create a custom grails tag that generated groovy code similar to "<g:if>" and "<g:else>"?
Using the normal grails taglib, I'm able to generate html or raw output, but I'm looking to output code that can be interpreted similar to how the if and else tags work.
Here's a sample of the Grails source code for the "if" tag:
#Override
protected void outputStartTag(String envExpression, String testExpression) {
out.print("if(");
out.print(envExpression);
out.print(" && ");
out.print(testExpression);
out.println(") {");
}
How can I do something similar in my own taglib prefix.
Example:
<mine:doSomethingCool key="foo">This text is conditionally shown</mine:doSomethingCool>
In addition to hiding complex logic, I would like this ability so I can use the <g:else> tag after my custom tag.
In general, I would like another tool in my toolbox in addition to the current taglib format.
If for example you only want to render the conditional text when key == 'foo', you could do that like this:
class SomethingTagLib {
static namespace = "ns"
def doSomethingCool = { attrs, body ->
if (attrs.key == 'foo') {
out << body()
}
}
}
You could then use this tag like so:
<ns:doSomethingCool key="foo">This text is conditionally shown<ns:doSomethingCool>
I'm trying to avoid referencing the concrete type library in my main project, but I'm getting this error:
No default instance or named instance 'Default' for requested plugin type StackExchangeChatInterfaces.IClient
1.) Container.GetInstance(StackExchangeChatInterfaces.IClient ,{username=; password=; defaultRoomUrl=; System.Action`2[System.Object,System.Object]=System.Action`2[System.Object,System.Object]})
I've setup my container to scan for assemblies, like so:
var container = new Container(x =>
{
x.Scan(scan =>
{
scan.AssembliesFromApplicationBaseDirectory();
scan.ExcludeNamespace("StructureMap");
scan.WithDefaultConventions();
scan.AddAllTypesOf<IMessageHandlers>();
});
//x.For<IClient>().Use<Client>(); //GetInstance will work if this line is not commented out.
});
When I try to get an instance, I get the error, my code for getting an instance is here:
chatInterface = container
.With("username").EqualTo(username)
.With("password").EqualTo(password)
.With("defaultRoomUrl").EqualTo(roomUrl)
.With<Action<object, object>>(delegate(object sender, object messageWrapper)
{
string message = ((dynamic)messageWrapper).Message;
Console.WriteLine("");
Console.WriteLine(message);
foreach (var item in messageHandlers)
{
item.MessageHandler.Invoke(message, chatInterface);
}
}).GetInstance<IClient>();
If I explicitly map the concrete class to the interface, everything works hunky dory, but that means I need to reference the project that Client is in, which I don't want to do.
This is really interesting. Looks like default conventions are not able to register types with such constructor (tried on both versions 2.6.3 and 3+). I was only registered when only parameterless constructor was specified. Looking at sources of both versions it is really suspicious as it should be registered. Deeper dive into the code would be needed...
Anyway try using custom registration convention:
public class ClientConvention : IRegistrationConvention
{
public void Process(Type type, Registry registry)
{
if (type.IsClass && !type.IsAbstract && !type.IsGenericType &&
type.GetInterfaces().Contains(typeof(IClient)))
{
registry.For(typeof(IClient)).Use(type);
}
}
}
Configure it like this:
var container = new Container(
c => c.Scan(
s =>
{
s.ExcludeNamespace("StructureMap");
s.WithDefaultConventions();
s.Convention<ClientConvention>();
s.AddAllTypesOf<IMessageHandlers>();
}));
and this should work just fine.
The default type scanning will not pick up concrete types whose constructor functions contain primitive arguments like strings, numbers, or dates. The thinking is that you'd effectively have to explicitly configure those inline dependencies anyway.
"but that means I need to reference the project that Client is in, which I don't want to do."
Does that actually matter? I think you're making things harder than they have to be by trying to eliminate the assembly reference.
I'm updating a SilverStripe website from 2.4 to 3.1.
I have many Links functions used in controllers and views.
The problem is that when I set routes.yml like this
Director:
rules:
'gottesdienste//$Action/$ID/$OtherID' : LiturgiesPage_Controller
'veranstaltungen//$Action/$ID/$OtherID' : ArrangementsPage_Controller
Links in my site change from
gottesdienste/archive/2012
to
LiturgiesPage_Controller/archive/2012
How do I fix this?
You need to implement a custom Link() method that uses the base string you want.
public function Link($action = null) {
return self::join_links('gottesdienste', $action);
}
A multitenancy application is an app that is shared by multiple organizations (medical practices, law offices..) and each organization, in turn, has it's own users. They all log on a centralized environment.
To be identified within the application, the organization must be expressed in the URL. There are two major URL forms for that. Subdomains and folders:
[tenancy_name].appname.com/projects/view/123
www.appname.com/[tenancy_name]/projects/view/123
At first I tried the second because this solution does not involve dealing with DNSs. But then the problem: Everytime the developer needs to express an url (#Html.Action or #Url.Action) it has to explicitly pass the [tenancy_name]. This adds an unwanted overhead to the development. A possible workaround would be to implement custom versions of these HTML helpers that automatically take into account the tenancy name. I'm considering this option but looking for something more straitghtforward. I also realized ASP.NET MVC automatically passes route values for outgoing URLs but only when the controller and action are the same as the current. It would be nice if route values were always passed.
To implement the first option, the subdomain one, I think, I would need some third party DNS manager. I heard of DynDNS and took a look at it but I thought it unclear how they work just looking at their site. Would I need to trigger a web-service to tell them to create another subdomain everytime a new tenancy is created? Do they support wildcards in the DNS? Do they work on Windows Azure or shared hostings?
I'm here looking for directions. Which way should I go?
look this project on codeplex, the "baseRoute" maybe can help you.

Following made View resolution trivial in our app:
How to use:
For views that you need to overload for a particular tenant - treat them same way as custom display modes:
Following will work:
Index.cshtml
Index.cust2.mobile.cshtml
or
Partials/CustomerAgreement.cust1.cshtml
Partials/CustomerAgreement.cust2.cshtml
as far as I remember display/editor templates also work same way
Known issues:
1. You have to create Layouts for all combinations of primary+secondary (for whatever MVC-reason)
2. Regardless of what resharper is saying about its support of display modes - it does not support "." as part of the display mode name (here's an issue to track progress http://youtrack.jetbrains.com/issue/RSRP-422413)
//put in application start --------
DisplayModeProvider.Instance.Modes.Clear();
foreach (var displayMode in GetDisplayModes())
{
DisplayModeProvider.Instance.Modes.Add(displayMode);
}
private IEnumerable<IDisplayMode> GetDisplayModes()
{
return new CompoundDisplayModeBuilder()
.AddPrimaryFilter(_ => dependencyResolver.GetService(typeof(IResolveCustomerFromUrl)).GetName(),
"cust1",
"cust2")
.AddSecondaryFilter(ctx => ctx.Request.Browser.IsMobileDevice, "mobile")
.BuildDisplayModes();
}
//end of application start part
//and the mode builder implementation:
public class CompoundDisplayModeBuilder
{
private readonly IList<DefaultDisplayMode> _primaryDisplayModes = new List<DefaultDisplayMode>();
private readonly IList<DefaultDisplayMode> _secondaryDisplayModes = new List<DefaultDisplayMode>();
//NOTE: this is just a helper method to make it easier to specify multiple tenants in 1 line in global asax
//You can as well remove it and add all tenants one by one, especially if resolution delegates are different
public CompoundDisplayModeBuilder AddPrimaryFilter(Func<HttpContextBase, string> contextEval, params string[] valuesAsSuffixes)
{
foreach (var suffix in valuesAsSuffixes)
{
var val = suffix;
AddPrimaryFilter(ctx => string.Equals(contextEval(ctx), val, StringComparison.InvariantCultureIgnoreCase), val);
}
return this;
}
public CompoundDisplayModeBuilder AddPrimaryFilter(Func<HttpContextBase, bool> contextCondition, string suffix)
{
_primaryDisplayModes.Add(new DefaultDisplayMode(suffix) { ContextCondition = contextCondition });
return this;
}
public CompoundDisplayModeBuilder AddSecondaryFilter(Func<HttpContextBase, bool> contextCondition, string suffix)
{
_secondaryDisplayModes.Add(new DefaultDisplayMode(suffix) { ContextCondition = contextCondition });
return this;
}
public IEnumerable<IDisplayMode> BuildDisplayModes()
{
foreach (var primaryMode in _primaryDisplayModes)
{
var primaryCondition = primaryMode.ContextCondition;
foreach (var secondaryMode in _secondaryDisplayModes)
{
var secondaryCondition = secondaryMode.ContextCondition;
yield return new DefaultDisplayMode(primaryMode.DisplayModeId + "." + secondaryMode.DisplayModeId){
ContextCondition = ctx => primaryCondition(ctx) && secondaryCondition(ctx)
};
}
}
foreach (var primaryFilter in _primaryDisplayModes)
{
yield return primaryFilter;
}
foreach (var secondaryFilter in _secondaryDisplayModes)
{
yield return secondaryFilter;
}
yield return new DefaultDisplayMode();
}
}
I have a component that has been happily building and rendering menus for a while now. Now I have to provide for a special case that shares all of the same logic, but requires a little bit of work in front of what already exists. What I'd like to do is create a new component action that will do the necessary preprocessing, punt to shared logic to complete the computational side and then render through the existing template partial (when all is said and done, it's still a menu like any other--it just take a little more work to build it).
Unfortunately, I can't find any way of doing this.
Here's the high level file/code breakdown that I have right now:
#
# navigation/actions/components.class.php
#
public function executeMenu() {
/**
* This method runs most of the menus and does most of the work
* that's required of the special case.
*
* Once complete, of course, it renders through navigation/templates/_menu.php
*/
}
public function executeSpecialMenu() {
/**
* Do some preparatory work and delegate to executeMenu()
* to finish up and render the menu. I'd like this action
* to render through the _menu.php partial as well.
*/
}
#
# templates/layout.php
#
<?php include_component( 'navigation', 'menu', array( 'menu' => 'Entity Type' ) ) ?>
/** SNIP */
<?php include_component( 'navigation', 'SpecialMenu' ) ?>
Any input would be much appreciated.
A simple if non-optimal way would be to create the _SpecialMenu.php partial and just place an include inside it:
<?php include_partial('navigation/menu', array('menu' => 'Entity Type', 'other_var' => $other_var) ?>
Where each of your variables will need to be passed to the partial as in $other_var. Does this at least solve the problem?
A more elegant solution is to use the get_partial inside the "second" component's execute function, like so:
public function executeSpecialMenu() {
//forces SpecialMenu to render _menu.php
echo get_partial('menu', $this->varHolder->getAll());
return sfView::NONE;
}
The call to varHolder->getAll gets all the variables that were going to be passed to the "normal" partial, since get_partial requires that.
Or, as a new method:
public function executeSpecialMenu() {
return $this->renderAlternatePartial('menu');
}
protected function renderAlternatePartial($partial) {
echo get_partial($partial, $this->varHolder->getAll());
return sfView::NONE;
}
Also there exists a renderPartial('xxx') method in the action class which is useful when it is needed to generate a part without template in cases such as XmlHttpRequest s:
if ($request->isXmlHttpRequest())
{
return $this->renderPartial('module/action', array('param' => 'value'));
}
I haven't tested if this works in the component execute methods. If this does not work it is a good idea to add such a functionality to symfony sfComponent class.
In the action/template mode, there exists a $this->setTemplate('xxx') method (in the action class) which can use a same template for different actions. (e.g same template for new or edit actions). Would that there was such a method in the component classes.
I wouldn't recommend to use different actions to render the same entity. Try to combine them and call a component with different parameters, and if it is heavy, move all the logic to a separate class.
