Is there a way to destroy Rails Active Record entries in a table without an id
column? I know there are a few ways to destroy Active Records with ids
, like these:
User.destroy(1)
User.first.destroy
However, I cannot seem to find a way to do so without an id
. I've checked the suggestions in this link but to no avail. Ideally, what I have in mind is something like this:
User.where(name: "Dummy").destroy
# Returns this:
# ArgumentError (wrong number of arguments (given 0, expected 1))
I know that it's generally discouraged to create tables in Rails without an id
column. While I'd like to rid of it for this particular table if possible, I am willing to make the column if it turns out there are no workarounds. Thanks in advance.
The reason User.where(name: 'Dummy').destroy
doesn't work is User.where(name: 'Dummy')
is a relation, not a single record. If you want, for example, to destroy all the records with name
equal to 'Dummy'
, you can use destroy_all
:
User.where(name: 'Dummy').destroy_all
if you want to remove column, you can use
User.find_by_name(name: "dummy").destroy
