else
system("echo -en '\\033[1;31mCannot commit, formating failing. Use --no-verify to force commit.\\033[0;39m\n'")

Your configuration file only defines excludes for the Rails department of cops, so it is correct that BlockLength, which is in the Metrics department, still inspects the files.
If what you meant to do was to ignore these files for all cops, you can use:
AllCops:
Exclude:
- 'db/**/*'
- 'config/**/*'
- 'script/**/*'
- 'bin/{rails,rake}'
- 'vendor/**/*'
- 'spec/fixtures/**/*'
- 'tmp/**/*'
Rails:
Enabled: true
Or if you just want to exclude the files for the Metrics cops, substitute AllCops for Metrics in the configuration above.
