How in Ruby on Rails can you determine which account is a record from the database?

Question

Ruby on Rails

For example, there is the last record in the table Table.last.
How to find out what number of element it is in the table?

Answer 1

Based on the fact that when we use the .all method relative to the model and get an array, then:
For example, we are looking for users, your_item_id = Table.last.id, we got id=45.
Now let's remove all the id records of the table, create an empty array all_items_ids = [], then write a block like Table.all.each { |item| all_items_ids.push(item.id }
Now we get the index, your_item_index = all_items_ids.index{ |id| id == your_item_id }
I wrote the first thing that came to mind, don't blame me

Answer 2

Better describe the task, I feel you went the wrong way.
Are you doing pagination? :)

Answer 3

Table.where("id <= ?", Table.last.id).count
