Rails ActiveRecord How Can I turn off logging particular queries

问题

I am under developer mode in Rails.
I am trying to insert a record with binary data to DB using AR.

Edoc.create(
            :id_claim => @claim_index, 
            :id_material => @doc_code, 
            :size => @file_list.first[:size],
            :efile => params[:files][0].read
        )   

But It takes a lot of time because Rails logs that query with entire file content.

How Can I turn off logging particular queries?

回答1:

Try:

old_logger = ActiveRecord::Base.logger
ActiveRecord::Base.logger = nil
# your code here...

Restore logger:

ActiveRecord::Base.logger = old_logger; nil # nil just to suppress some garbage
