From error to fix in minutes
Revise automatically detects errors from your monitoring tools, analyzes the root cause, and creates pull requests with fixes and tests.
def update
@preferences = current_user.preferences
@preferences.settings['theme'] = params[:theme]
@preferences.save!
end
I've analyzed the error and identified the root cause:
preferences
association might be nil# Proposed fix:
def update
@preferences = current_user.preferences || current_user.create_preferences
@preferences.settings ||= {}
@preferences.settings['theme'] = params[:theme]
@preferences.save!
end

Implement features with a comment

We need to implement a rate limiting feature for our API endpoints. Can Revise help with this?
/revise implement rate limiting for API endpoints using Redis
I'll help implement rate limiting using Redis. Here's my plan:
# Example implementation:
module RateLimiter
extend ActiveSupport::Concern
included do
before_action :check_rate_limit
end
private
def check_rate_limit
key = "rate_limit:#{request.ip}"
count = Redis.current.get(key).to_i
if count >= max_requests
render json: { error: 'Rate limit exceeded' },
status: :too_many_requests
else
Redis.current.multi do |redis|
redis.incr(key)
redis.expire(key, window_seconds)
end
end
end
end
