Writing for-each loop inside HAML and Rails

Question

I have a HAML like this:

- @my_patients_list.each do |patient|
  %tr
    %td= patient.name
    %td= patient.date_of_birth
    %td= patient.gender
    %td= patient.brand_name.name
    %td= patient.generics[0].name

notice the line %td= patient.generics[0].name I am cheating and only printing the first generic. But each patinet can have more than one generic. So it is a matter or another for-each loop for that part. But this HAML I just started using it and still not used to it. Can someone help out with that extra loop I should write in HAML format so I can replace it with patient.generics[0].name ? Probably let's just separate their generics names with a comma.

Solution 1

Assuming generics is a string array and you want to separate by new td...

- @my_patients_list.each do |patient|
  %tr
    %td= patient.name
    %td= patient.date_of_birth
    %td= patient.gender
    %td= patient.brand_name.name
    - patient.generics.each do |gen|
       %td= gen.name

Otherwise if you just want to separate by comma...

- @my_patients_list.each do |patient|
      %tr
        %td= patient.name
        %td= patient.date_of_birth
        %td= patient.gender
        %td= patient.brand_name.name
        %td= patient.generics.map(&:name).join(',')  

Solution 2

If you want to seperate the generics name by comma, you may try this:

- @my_patients_list.each do |patient|
  %tr
    %td= patient.name
    %td= patient.date_of_birth
    %td= patient.gender
    %td= patient.brand_name.name
    %td= patient.generics.map(&:name).join(',')           

It will print all associated generic names seperated by comma.

This will create table rows with varying numbers of td elements, which is likely not be what you want.
