method

content_type=

v8.1.1 - Show latest stable - Class: ActionDispatch::Response

content_type=(content_type)

public

Sets the HTTP response’s content MIME type. For example, in the controller you could write this:

response.content_type = "text/html"

This method also accepts a symbol with the extension of the MIME type:

response.content_type = :html

If a character set has been defined for this response (see #charset=) then the character set information will also be included in the content type information.
