Case Empty in Web3 Json Array Output

Hello and welcome…

It’s possible to test for empty with is_nil.

But I would do like this…

<%= render_coins(hot_coins[“market_data”][“total_supply”]) %>

# then write the helper functions
def render_coins(nil) do
  # show loop image
end
def render_coins(coins) do
  ...
end

It has the advantage to clean up the template, and to use a simple pattern match for the render.

BTW: You can wrap your code with ``` to format it, like in Markdown,

i kind of find the solution

<%= if (@output[“market_data”][“total_supply”] != nil) do%>
<%= @output[“market_data”][“total_supply”] %> M
<%else %>
UNLIMITED

                  <% end %>

but it looks bad, did you have any advice for it?

SOLVED

i have found another solution using Enum.empty?() instead of != nil
