Instance Method Details

#parse(content) ⇒ Object

Forgiving parse for the RENDER path — a template already in the database
must still send, so a syntax error degrades to RawFallbackTemplate
rather than blowing up an order confirmation.

Use #parse! on the SAVE path instead. Rescuing here means callers that
write rescue Liquid::SyntaxError around this method are unreachable.

def parse(content)
  parse!(content)
rescue Liquid::SyntaxError => e
  ErrorReporting.error(e, context: "Liquid parse failed for content (#{content.to_s[0, 80]}...)")
  RawFallbackTemplate.new(content)
end

#parse!(content) ⇒ Object

Strict parse for the SAVE path — raises Liquid::SyntaxError so a
validation can surface it to whoever is editing the template.

Raises:

  • (Liquid::SyntaxError)
