I am calling render_to_string on an action of a different controller. I am
not sure if this is just in Rails 3 (I am using) or if it would have
presented in previous versions. I especially don't understand why this
method should ignore :controller => "xx" and assume the current controller.
Here are a few of the trials and results:
*html_to_save = render_to_string(:action => "/comparisons#display", :layout
=> "application")*
*returns* (in addition to a deprication error)*:*
ActionView::MissingTemplate: Missing template /comparisons#display with
{:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html],
:locale=>[:en, :en]} in view paths
"/Users/DK/Documents/ror/projects/creditcompare3/app/views"
*
html_to_save = render_to_string(:action => "/comparisons/display", :layout
=> "application")
*returns:
ActionView::Template::Error: Missing partial web_requests/display with
{:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html],
:locale=>[:en, :en]} in view paths
"/Users/DK/Documents/ror/projects/creditcompare3/app/views"
*html_to_save = render_to_string(:controller => "comparisons", :action =>
"display", :layout => "application")
returns*:
ActionView::MissingTemplate: Missing template web_requests/display with
{:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html],
:locale=>[:en, :en]} in view paths
"/Users/DK/Documents/ror/projects/creditcompare3/app/views"
*
html_to_save = render_to_string(:action => "display", :layout =>
"application")
returns* (obviously):
ActionView::MissingTemplate: Missing template web_requests/display with
{:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html],
:locale=>[:en, :en]} in view paths
"/Users/DK/Documents/ror/projects/creditcompare3/app/views"
In the Rails source I find:
# Raw rendering of a template to a string. Just convert the results of
# render_to_body into a String.
# :api: plugin
def render_to_string(*args, &block)
options = _normalize_args(*args, &block)
_normalize_options(options)
render_to_body(options)
end
# Raw rendering of a template to a Rack-compatible body.
# :api: plugin
def render_to_body(options = {})
_process_options(options)
_render_template(options)
end
# Find and renders a template based on the options given.
# :api: private
def _render_template(options) #:nodoc:
view_context.render(options)
end
So I new to reading the source but is the problem that it is using the
view_context which I would assume would be that which the current controller
owns? That would seems to confirm the errors and ignorance of the controller
attribute.
Thanks,
David
