Method: Tml::Tokens::Data#token_value_from_hash_param

Defined in:
lib/tml/tokens/data.rb

#token_value_from_hash_param(hash, language, options) ⇒ Object

Hashes are often used with JSON structures. We can be smart about how to pull default values.

examples:

tr(“Hello user”, => {:name => “Michael”, :gender => :male}}

tr(“Hello user”, => {:object => {:gender => :male, :value => “Michael”}}} tr(“Hello user”, => {:object => {:name => “Michael”, :gender => :male, :property => :name}}} tr(“Hello user”, => {:object => {:name => “Michael”, :gender => :male, :attribute => :name}}}

tr(“Hello user”, => {:object => user, :value => “Michael”}} tr(“Hello user”, => {:object => user, :property => :name}} tr(“Hello user”, => {:object => user, :attribute => :name}}
