existing atoms about better_params HOT 2 OPEN

This should not be possible as atoms are never garbage collected by the Erlang VM.

The best way to use better_params is to use atom literals in the codebase, which ensure that those params are atomized. E.g.:

params.id
# or
params[:some][:nested][:value]

# instead of
params[:"dynamic_#{key}"]

Can you provide more details about your Elixir & Erlang version, OS, and ideally an MCVE so I can try to reduce it?

Hello sheharyarn, I just meet the same problem.

I write a POST API with nested params in body params. When send request, it lost params casually inside nested struct. I replaced to_existing_atom by to_atom, it solved.
