Well I managed to scrap something together. Here's my code:
[...snip...]
before_filter :setup_counts
def seeking_reviewers
hobo_index @seeking_reviewers ||= Manuscript.search("seeking_reviewers",
:status)
end
def at_review
hobo_index @at_review ||= Manuscript.search("at_review", :status)
end
def back_from_review
hobo_index @back_from_review ||= Manuscript.search("back_from_review",
:status)
end
def pending_resubmission
hobo_index @pending_resubmission ||=
Manuscript.search("pending_resubmission", :status)
end
private
def setup_counts
@received_count ||= (@received = Manuscript.search("received",
:status)).count
@seeking_reviewers_count ||= (@seeking_reviewers =
Manuscript.search("seeking_reviewers", :status)).count
@at_review_count ||= (@at_review = Manuscript.search("at_review",
:status)).count
@back_from_review_count ||= (@back_from_review =
Manuscript.search("back_from_review", :status)).count
@pending_resubmission_count ||= (@pending_resubmission =
Manuscript.search("pending_resubmission", :status)).count
end
And then, in my main-nav definition:
<nav-item href="&received_manuscripts_path">Received (<%= @received_count
%>)</nav-item>
<nav-item href="&seeking_reviewers_manuscripts_path">Seeking Reviewers (<%=
@seeking_reviewers_count %>)</nav-item>
<nav-item href="&at_review_manuscripts_path">At Review (<%= @at_review_count
%>)</nav-item>
<nav-item href="&back_from_review_manuscripts_path">Back From Review (<%=
@back_from_review_count %>)</nav-item>
<nav-item href="&pending_resubmission_manuscripts_path">Pending Resubmission
(<%= @pending_resubmission_count %>)</nav-item>
I'd love some criticism on my approach. Particularly, do I even need the
||= on the action definitions? Since setup_counts is run as a
before_filter, am I being overly cautious by safe-assigning the collection
variables again?
And finally, is there a way to print an instance variable using the view:
tag?
