In my project I want to index the data.
The code of views:
- @phones.each.with_index(1) do |(phone,no_of_duplicate),index|
.row.py-2
.col-2 = index
- if no_of_duplicate.count > 1
.col-3 = phone
.col-3 = no_of_duplicate.count
.col-4 .......................................
I obtain the result as If I change the code on views as:
- @phones.each.with_index(1) do |(phone,no_of_duplicate),index|
- if no_of_duplicate.count > 1
.row.py-2
.col-2 = index
.col-3 = phone
.col-3 = no_of_duplicate.count
How can I solve this?
您可以在分配索引和渲染之前进行filter
:
@phones.filter { |(_,no_of_duplicate)| no_of_duplicate.count > 1 }.each <...>
