[...] If you need to relay your Doctrine events to symfony, you might get tempted to create a dependency to sfContext in your models. As we all know (right?) this is a path straight down to hell. [...]

Load the Url symfony helper in a model or form class…

I’m doing some symfony work and needed to use the Url helper in a form class to return an error message that included a link. I would consider this one of those exceptions where you really need to be able to have markup in a class rather than in a tem…

@Interested: Just inject the I18N instance into the form. I’m doing that too.

$form = new myForm($i18n, …);

And concerning the helpers… it’s probably better not to use them at all and rely on the underlying implementation. format_date(), f.i., is just a wrapper for sfNumberFormat. So use sfNumberFormat instead.

@John: What do you mean? In the form? Inject them.

How is it possible to get “multiple sfUser instances” ?

And how about I18n or other helpers loading in Form, or Model class (sfContext::getInstance()->getConfiguration()->loadHelpers(‘I18N’);)

I’ve usually come across this when using sfForm and I get around this by using the constructor injector mentioned above but pass the object I want as an option i.e.

$form = new myForm(array(), array(‘sf_guard_user’ => $user));

Passing it in this manner allows me to access it in the form class via $this->options['sf_guard_user'];

@gpilotino, Yeah, how is sfContext::getInstace() avoidable from the generator, and also from the form classes? is it possible to inject dependency on the forms too?

THANKS ;
I have been struggling with dependency injection forever, this really helps!

I can see another situation where you cannot avoid using sfContext::getInstance(): the admin generator.
(ie. how can you have a table_method / peer_method filtered on user credentials without accessing context from the Model ?)
