Ruby on Rails - Action Mailer 400 Bad request - ruby-on-rails

Question

I'm having the following error when I try send a form with Ruby on Rails 4.1 and Action Mailer:
Started POST "/contact_sponsors" for 127.0.0.1 at 2018-05-17 16:22:35 -0300
Processing by ContactSponsorsController#create as JS

Completed 400 Bad Request in 16ms (Views: 0.8ms | ActiveRecord: 4.8ms)
Anyone can help me? I've tried to sort this out in many ways but to no avail. Here is my Controller, Mailer and Model:
class ContactSponsorsController < InheritedResources::Base
def create
#contact_sponsor = ContactSponsor.new
if #contact_sponsor.save
ContactSponsorMailer.delay_for(10.seconds, retry: true).create(#contact_sponsor)
render nothing: true, status: 200
else
render nothing: true, status: 400
end
end
end
class ContactSponsorMailer < ActionMailer::Base
default from: "Facens Lince <no-reply#facens.br>"
def create(contact_sponsor)
#contact_sponsor = contact_sponsor
mail(to: "felipe.marcon#atua.ag", subject: "Contato Através do Site")
end
end
class ContactSponsor < ActiveRecord::Base
validates :company_cnpj, :company_address, :company_number, :company_size, :company_existence, :company_sponsor_type, :responsible_name, :responsible_email, presence: true
end
Thanks.

Answer 1

Look, in the ContactSponsor you have validate those data which must be present but you have not passed any data that means empty that's why
Completed 400 Bad Request
and for this, you need to create a private method for strong parameters look at that below
class ContactSponsorsController < InheritedResources::Base
def create
#contact_sponsor = ContactSponsor.new(contact_sponsor_params)
if #contact_sponsor.save
ContactSponsorMailer.delay_for(10.seconds, retry: true).create(#contact_sponsor)
render nothing: true, status: 200
else
render nothing: true, status: 400
end
end
private
def contact_sponsor_params
params.require(:contact_sponsor).permit(:company_cnpj, :company_address, :company_number, :company_size, :company_existence, :company_sponsor_type, :responsible_name, :responsible_email)
end
end
I think it will work.

Answer 2

#contact_sponsor.save returned false therefore it returns 400.
Check the errors you had with #contact_sponsor.errors.full_messages when it returns false, or use save! to raise an exception (discouraged, use it only for debugging) and see what went wrong.

Answer 3

As per the logs shown and code snippet shared, it seems like the attribute "company_sponsor_type" seems to be blank string and in the model you have the written the presence true of the same attribute and thus it is getting rolled back.
So either remove the validation or send some value in the company_sponsor_type key.
