I have a rather atypical set-up in one of my Rails controllers in that it can create a series of objects (instead of only a single one) depending the parameters received.
I'd like the controller to respond_to js and pass such group of objects, just created, as an array to my js.erb file.
Unfortunately, I haven't been able to pass the array to JS in the appropriate format.
A bit of pseudo code to illustrate my controller below:
Controllers/verbatims_controller.rb
def create
# Code here returns an array of strings
# Each string of the array is converted into a Verbatim instance
# I create again an array of strings by 'plucking' the 'content' attribute (a string) from each verbatim object
# I set @verbatims to take the value of that array of strings as below
@verbatims = @answer.verbatims.pluck(:content)
# At this point I'm sure @verbatims returns an array of the form ["string_1", "string_2", "string_n"]
respond_to do |format|
format.js { render 'verbatims_for_answers.js.erb'
end
end
Views/verbatims/verbatims_for_answers.js.erb
// I set my JS variable as below
var verbatims = ("<%= j @verbatims.to_json %>");
// which returns a string like:
"["string_1","string_2","string_n"]"
I have tried using raw as suggested in a post in StackOverflow without success like:
var verbatims = ("<%= raw @verbatims.to_json %>");
Or converting to json from the controller but still no luck.
Hope you can help.
"<%= @verbatims.to_json.html_safe %>""<%= j @verbatims.to_json.html_safe %>"and it works to get rid of the " but it still results in a string like this:"["s_1", "s_2", s_n"]"
