ruby on rails - Is it possible to convert a string into a partial? -


i have string stored in database used custom layout.

i parse custom layout inside of app layout, using :

render_to_string(partial: custom_template, layout: "pdf_template", locals: locals)

where custom_template string db. however, when try :

nomethoderror: undefined method `to_sym' nil:nilclass

is possible i'm doing? if so, can complete this?

i've noted can try things :

render_to_string(text: template, locals: locals, template: "pdf_template")

and

render_to_string(inline: template, locals: locals, template: "pdf_template")

but doing so, can't find template , returns :

actionview::missingtemplate: missing template layouts/pdf_template {:handlers=>[:erb, :builder, :coffee, :haml], :formats=>[:pdf], :locale=>[:en, :en]}. searched in:   * "/users/elephanttrip/sites/shasta/app/views"

which strange because worked fine in current location , definition.

if want store views in database, should use rendering engine rather in rails default. check liquid gem (http://railscasts.com/episodes/118-liquid, http://rubygems.org/gems/liquid).

for example, use gem render emails our maillists (their templates stored in db).
