How can I specify a search field for Elastic Search - FATAL -- : [...] ArgumentError (Must specify fields to search): - searchkick

Question

My rails 5 app is deployed to Heroku, but the search function results in a 500 status and tells me that I need to specify a search field for Elastic Search. Any help would be greatly appreciated.

Answer 1

It looks like your search parameter attribute is not whitelisted in your Movies controller.
# Never trust parameters from the scary internet, only allow the white list through.
def movie_params
params.require(:movie).permit(:title, :description, :movie_length, :director, :image, :rating)
end
In theory you can do something like ...
# Never trust parameters from the scary internet, only allow the white list through.
def movie_params
params.require(:movie).permit(:title, :description, :movie_length, :director, :image, :rating, :search)
end
Now when sending the params , just make sure it's wrapped in a movie object Parameters: {"utf8"=>"✓", "movie" => {"search"=>"deadpool"}}
Now just reference it accordingly in line 8 of your controller, so instead of params[:search], you'll now use movie_params[:search]. Did not test it, let me know if it works out.
