On tap for tonight are some breadcrumbs for the show meal page. For a meal prepared today (May 31, 2009), there should be breadcrumb links to the list of meals in May, and to the list of meals in 2009.
The link to meals this year, in RSpec notation:
it "should display a breadcrumb link to the other meals in this year" do(the
render("/views/meal.haml")
response.should have_selector(".breadcrumbs a",
:href => "/meals/#{@year}")
end
@year instance variable comes from the before(:each) block).To make this example pass, I add the following Haml code:
- date = Date.parse(@meal['date'])It is debatable if parsing the date string, as I do here, or splitting the date string on dashes (e.g.
.breadcrumbs
%a{:href => "/meals/#{date.year}"}= date.year
"2009-05-31".split(/-/)[0]) is the easiest thing to do. I make an educated guess here that things will be easier for me if I have a Date object.With the year breadcrumb in place, it is time for the month breadcrumb. The RSpec example:
it "should display a breadcrumb link to the other meals in this month" do(Note: I'm using the
render("/views/meal.haml")
response.should have_selector(".breadcrumbs a",
:href => "/meals/#{@year}/#{"%02d" % @month}")
end
% shortcut for sprintf in that example)To make that example pass, I make use of the
strftime method on the date object (that date object did come in handy):- date = Date.parse(@meal['date'])From
.breadcrumbs
%a{:href => "/meals/#{date.year}"}= date.year
>
%a{:href => "/meals/#{date.strftime("%Y/%m")}"}= date.strftime("%B")
cheat strftime, the options that are being used:%B - The full month name (``January'')
%m - Month of the year (01..12)
%Y - Year with century
With that code work done, I am ready to move on back out to the Cucumber scenario:
I use Cucumber's suggestion to define the next, very simple, step:
When /^I click the "([^\"]*)" link$/ do |text|That simple step gets me tantalizingly close to being done with this scenario. There is much blue (not reached, but implemented steps) and only three remaining steps to be implemented (two of them the same):
click_link text
end
I implement the next step (Then I should see "Focaccia!" in the list of meals):
Then /^I should see "([^\"]*)" in the list of meals$/ do |title|Unfortunately, when I run the scenario through Cucumber, I find:
response.should have_selector("a", :content => title)
end
cstrom@jaynestown:~/repos/eee-code$ cucumber features -n \Aw nuts. When I implemented the list of meals, I failed to actually link to the meal. That is a fairly easy thing to resolve. Tomorrow.
-s "Browsing a meal on a specific date"
Feature: Browse Meals
So that I can find meals made on special occasions
As a person interested in finding meals
I want to browse meals by date
Scenario: Browsing a meal on a specific date
Given a "Focaccia" recipe from March 3, 2009
Given a "Focaccia!" meal with the "Focaccia" recipe on the menu
When I view the "Focaccia!" meal
Then I should see the "Focaccia!" title
And I should see a "Focaccia" recipe link in the menu
When I click the "March" link
Then I should see "Focaccia!" in the list of meals
expected following output to contain a <a>Focaccia!</a> tag:
