How to remove a key/value pair from a nested hash in params?

Question

I would like to remove a key/value from a nested hash in my params.

My params are:

Parameters: {"utf8"=>"✓", "q"=>{"upward_trending"=>"", "downward_trending"=>"", "name_cont"=>"test", "category_id_in"=>["1", ""], "country_eq"=>"", "end_date_gteq"=>"", "end_date_lteq"=>""}, "commit"=>"Filter", "type"=>"Dailyd eal"}

I would like to remove name_cont from the q hash.

I am able to remove the full hash by doing:

request.query_parameters.except(:q)

or

params.except(:q)

But everytime I try anything like:

except(:q[:name_cont]) except("name_cont") except([:q][:name_cont])

I get errors.

Any ideas?

You should try

request.query_parameters[:q].except(:name_cont) # or params[:q].except(:name_cont)

You can use except! also if you want in-place modification.
