Password not filtered in log - ruby-on-rails

Question

According to Rails documentation
config.filter_parameters used for filtering out the parameters that
you don't want shown in the logs, such as passwords or credit card
numbers. By default, Rails filters out passwords by adding
Rails.application.config.filter_parameters += [:password] in
config/initializers/filter_parameter_logging.rb. Parameters filter
works by partial matching regular expression.
So, why when I submit the form below
<%= form_with model: #user, url: admin_user_path, method: :delete do %>
<%= label_tag :password, t('forms.password') %>
<%= text_field_tag :password, nil %>
<%= button_tag t('forms.save'), type: 'submit' %>
<% end %>
I can see my password in the log?
<ActionController::Parameters {"utf8"=>"✓", "_method"=>"delete", "authenticity_token"=>"r22P2Mi1xcWOjRHGogoFaDcOec9/FgkC9btCo66qmqaKG/zwzUkbUGtATsTKV19OOYK80VBf1h0CzFtoRltQOA==", "password"=>"x", "button"=>"", "controller"=>"admin/users", "action"=>"destroy", "id"=>"at-example-com"} permitted: false>
Shouldn't the password be [FILTERED]?

Answer 1

The piece of code you're showing isn't from a log:
<ActionController::Parameters {"utf8"=>"✓", "_method"=>"delete", "authenticity_token"=>"r22P2Mi1xcWOjRHGogoFaDcOec9/FgkC9btCo66qmqaKG/zwzUkbUGtATsTKV19OOYK80VBf1h0CzFtoRltQOA==", "password"=>"x", "button"=>"", "controller"=>"admin/users", "action"=>"destroy", "id"=>"at-example-com"} permitted: false>
That output from the command like puts(params). The option filter_parameters is about log file which placed under log directory. E.g. log/development.log
Here is a piece of log file:
Processing by UsersController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"mxQJeccoEATtyCFy1eV", "user"=>{"first_name"=>"Juggy Head", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Create user"}

Answer 2

You have used text_field_tag (It's going to input type text) that's why it's showing value in the log you need to use password_field_tag (It's going to input type password) like below
<%= form_with model: #user, url: admin_user_path, method: :delete do %>
<%= label_tag :password, t('forms.password') %>
<%= password_field_tag :password, nil %>
<%= button_tag t('forms.save'), type: 'submit' %>
<% end %>

For instance, password filtering to use above code
