I have a rails app that sends out many notification e-mails. We have a desire to let the user choose plain text vs html.
Initially our desire was always multipart so we didn’t set a content type and simplyhad both the email.html.erb & email.text.erb views, which would both get sent through and create a multipart.
However now when we specify the content_type based on the users preference a it does set itself properly to multipart or plain/text but the html template is included as plain text at the bottom of the plain text e-mail.
Here is the code:
Mailer Action:
def client_creation(client) # When client checks in for the first time
@client = client
content_type = client.company.html_emails ? nil : 'text/plain'
email_prefix = client.company.brand ? client.company.brand.email_subject_prefix : 'MonitoringClient'
mail(to: @client.company.administrative_reporting_address, subject: "[#{email_prefix}][Initial Check-in] #{@client.machine_name.html_safe} of #{@client.clientgroup.name}", content_type: content_type)
end
The above code checks if the Clients company has html_emails is on, if so it set the content_type to plain/text. Which results in the following:
IRB output:
#<Mail::Message:70269523266340, Multipart: false, Headers: <Date: Sun, 11 Nov 2012 09:09:43 -0600>, <From: notifications@monitoringclient.com>, <To: ommitted>, <Message-ID: <509fbfb7e0c4e_11e113fe8e4435b4084183@Jonathan.local.mail>>, <Subject: [Initial Check-in] Jonathan of hivemind labs>, <Mime-Version: 1.0>, <Content-Type: text/plain>, <Content-Transfer-Encoding: 7bit>>
So far so good Multipart is false content_type is text/plain but then here is the resulting email body:

Why all the mime part data, why is the html content visible as text? I want a plain text only e-mail. Is this not how that is achieved?
One thing i noticed is that the html section of the e-mail says content_type: ‘text/html’. Maybe that is why it’s being included? Can this be prevented?
This question seemed to be close but seems this person was just trying to work out how to send multipart, which is not our issue:
Rails mailer mimepart visible as text in message body
i also tried changing our text template to email.text.plain.erb after seeing that in a few places but that did not work either.
Here are the email headers if anyone is curious:

Since the mailer action is called
client_creation, this will render the template ‘client_creation.html.erb’ for the HTML part (if condition is true) and render the template ‘client_creation.text.erb’ for the text part.html_emailsis a flag set by the company to enable/disable html email.
