# Link to a Label
|
|
#
|
|
# label - Label object to link to
|
|
# project - Project object which will be used as the context for the label's
|
|
# link. If omitted, defaults to `@project`, or the label's own
|
|
# project.
|
|
# type - The type of item the link will point to (:issue or
|
|
# :merge_request). If omitted, defaults to :issue.
|
|
# block - An optional block that will be passed to `link_to`, forming the
|
|
# body of the link element. If omitted, defaults to
|
|
# `render_colored_label`.
|
|
#
|
|
# Examples:
|
|
#
|
|
# # Allow the generated link to use the label's own project
|
|
# link_to_label(label)
|
|
#
|
|
# # Force the generated link to use @project
|
|
# @project = Project.first
|
|
# link_to_label(label)
|
|
#
|
|
# # Force the generated link to use a provided project
|
|
# link_to_label(label, project: Project.last)
|
|
#
|
|
# # Force the generated link to point to merge requests instead of issues
|
|
# link_to_label(label, type: :merge_request)
|
|
#
|
|
# # Customize link body with a block
|
|
# link_to_label(label) { "My Custom Label Text" }
|
|
#
|
|
# Returns a String
