Hi @KarishmaVanwari, since you want the random cards to be displayed in the dashboard's sidebar shouldn't this be in home_controller?

plots2/app/controllers/home_controller.rb

Lines 39 to 59 in ca319fc

def dashboard_v2

@title = I18n.t('dashboard._header.dashboard')

# The new dashboard displays the blog and topics list

if current_user

@blog = Tag.find_nodes_by_type('blog', 'note', 1).limit(1).first

# Tags without the blog tag and everything tag to avoid double display

exclude_tids = Tag.where(name: %w(blog everything)).pluck(:tid)

@pagy, @tag_subscriptions = pagy(

TagSelection

.select('tag_selections.tid, term_data.name')

.where(user_id: current_user.id, following: true)

.where.not(tid: exclude_tids)

.joins("INNER JOIN term_data ON tag_selections.tid = term_data.tid")

.order("term_data.activity_timestamp DESC")

)

@trending_tags = trending

render template: 'dashboard_v2/dashboard'

else

redirect_to '/research'

end

end

Please let me know if I'm wrong or missing something.

What if we put it in a reusable named methodin application_controller so it can be used in multiple places?

I tried placing this piece of code on line 54 in home_conroller but it gives the following error -
NoMethodError in HomeController#dashboard_v2
undefined method normal_tags for nil:NilClass .

@jywarren, I tried this out, but it still doesn't seem to work as I am unable to find cards as expected on the dashboard.

That may be because you don't have nodes with those tags in your local development environment? Can you try tagging a note (not a wiki, i think this is just returning notes, right?) with "water-quality" or "air-quality"? If that doesn't work I will try running this code to debug. No worries!! Did you want to accept this suggestion and commit it?

KarishmaVanwari · 2022-09-02T01:44:58Z

Hi @jywarren, I've opened a PR #11380. Thanks!

jywarren · 2022-09-02T13:21:32Z

My apologies for mixing these all up, but i hid the subtopics discussion from this thread to try to clear it up. Looking at the issues here now!

jywarren · 2022-09-05T17:30:36Z

OK, so I had to make some edits to the dashboard code to make it work, but ultimately I found that Tag.get_recommendations("blog", "three") is not returning anything (i used "blog" because that's in the db seeds file so it exists).

So let's debug why that's not working. I think we may want to write a unit test for that code. That will let us test Tag.get_recommendations("blog", "three") in isolation and ensure it returns the right thing. Why don't I write the unit test and you can work on figuring out why it's not returning anything!

OK, here's the unit test. Let's ensure it returns something! We could even test how many nodes it returns, or something else. But most importantly that it returns nodes at all!

OK, see below where I made a further suggestion about the unit test: #11332 (comment) (it got collapsed because I accepted the change)

jywarren · 2022-09-06T23:17:07Z

Generally unit tests test individual functions in isolation, not in the context of a big running application all at once. They're useful for finding narrow reasons things may have gone wrong, and that individual pieces function as expected.

By contrast, integration tests, or system tests, are "full-stack" tests which start up the whole application and help us see how things might go wrong when everything is trying to work in synchrony, all at once.

Both types of test -- the narrow ones and the broad ones -- are useful for catching errors. Sometimes both get tripped! But I hope that way of thinking of different kinds of tests makes sense!

jywarren · 2022-09-06T23:23:03Z

test/unit/tag_test.rb

+  test 'Tag.get_recommendations' do
+    nodes = Tag.get_recommendations("blog", "test")
+    assert_not_nil nodes
+    assert nodes.length > 0


Aha! This assertion failed! So, looks like we have been getting an empty array back:

https://github.com/publiclab/plots2/runs/8217990567?check_suite_focus=true#step:5:85

TagTest#test_Tag.get_recommendations (23.30s) Expected false to be truthy. test/unit/tag_test.rb:301:in `block in <class:TagTest>'

Great, so now, we can try to fix that. Once we push a fix up as a commit to this PR, the test will start to pass again -- that's actually "Test Driven Development" -- we set up a specific enough test condition (or "assertion") that our test will pass once it's working properly. The test actually precedes the final solution!
