Hi!
First of all, thanks for this gem :)
I have an issue related to to_csv method output. I can't find a way to exclude headers from the output. I've tried to pass { write_headers: false } to csv_output, but without success.
Is there any possibility at the moment to avoid headers in serialized output?

Thanks!

Hi,

First of all, thanks for your work on this gem!

I have noticed that since version 3, the gem is no longer loaded correctly for Rails 7 at least. I had to downgrade to 2.0.2 to have access to the as_csv method on my records. Looks like the railtie is not functioning correctly?

Not sure what I'm doing wrong... I've installed the gem. ActiveModel::Serialization is included by models. Individual model to_csv method works fine. But to_csv on a relation doesn't work:

irb(main):014:0> Service < ActiveModel::Serialization
=> true
irb(main):015:0> Service.first.to_csv
=> "id,created_at,updated_at,type,name,gtfs_agency_id,logo,email,url,phone,start_or_end_area_id,trip_within_area_id,fare_structure,fare_details,archived\n1,2017-04-05 14:01:12 -0400,2017-04-20 13:34:28 -0400,Transit,Sample Transit Service,\"\",,,http://www.mbta.com,555-555-5555,,,,{:fare_table=>{}},false\n"
irb(main):016:0> Service.all.to_csv
undefined method `to_csv' for #<Service::ActiveRecord_Relation:0x007f9a4bbf5b20>
Did you mean?  to_s

From the readme it sounds like I should be able to just install the gem, include Serialization on my model, and call to_csv on a relationship. Am I missing something?

Thanks!

FYI I'm using Ruby 2.4.0, Rails 5.0.2

I am attempting to use this gem but getting an UnknownFormat error.

Are there steps I missed in configuring my app to use the gem?

# Enrollment Controller
  def roster
    respond_to do |format|
      format.csv { render csv: enrollments }
    end
  end

# Enrollment Model
def as_csv(options = {})
    attributes
end

I also have a serializer exposing attributes for enrollments, just trying to brain storm on next steps in debugging this. Any thoughts?

I've added gem in my Gemfile
bundled new gems

Added method in my controller
def export_csv respond_to do |format| format.csv do format.csv { render csv: Widget.all } end end end

But when I open localhost:3000/export_csv.csv it returns this error
