configurationsymfonytwig
I have a Symfony2 Twig template. I want to output the value of a config parameter in this twig template (a version number). Therefore I defined the config parameter like this:
parameters:
app.version: 0.1.0
I'm able to use this config parameter in Controllers but I have no clue how to get it in my Twig template.
In Rails 3, Application specific custom configuration data can be placed in the application configuration object. The configuration can be assigned in the initialization files or the environment files -- say for a given application MyApp:
MyApp::Application.config.custom_config_variable = :my_config_setting
or
Rails.configuration.custom_config_variable = :my_config_setting
To read the setting, simply call the configuration variable without setting it:
Rails.configuration.custom_config_variable
=> :my_config_setting
UPDATE Rails 4
In Rails 4 there a new way for this => http://guides.rubyonrails.org/configuring.html#custom-configuration
Rather than defining contact_email within app.config, define it in a parameters entry:
parameters:
contact_email: somebody@gmail.com
You should find the call you are making within your controller now works.

Parameter config:
Twig config:
Twig template:
This method provides the benefit of allowing you to use the parameter in
ContainerAwareclasses as well, using:
