#link_to_label(label, project: nil, type: :issue, tooltip: true, &block) ⇒ Object

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
