Class Method Details

.new_field(key, value) ⇒ Object

A quick method for doing

f = Field.new
f.key = key
f.value = value

One can then quickly add fields to an [active] workitem via :

wi.fields << Field.new_field("toto", "b")

This method does not save the new Field.

end

.search(text, storename_list = nil) ⇒ Object

Will return all the fields that contain the given text.

Looks in svalue and fkey. Looks as well in yvalue if it contains a string.
