Usually, we use like:
params[:a] #to get a specific parameter's value But how to get all the parameters the way we do in PHP?
$_GET or $_POST 1 Answer
You may simply use params as a Hash of all passed parameters (both GET and POST).
For example:
params.each do |key,value| Rails.logger.warn "Param #{key}: #{value}" end Update: Note, what params include parameters of categories:
- Path parameters (bound in routes)
- Query parameters (GET)
- Request parameters (POST)
If you want to access parameters of certain category only you may use:
request.path_parameters request.query_parameters # or request.GET request.request_parameters # or request.POST All methods return HashWithIndifferentAccess, so you may access them by string or symbol key.
