Hello I am trying to show the errors that can occur by uploading a file (file name, size). I tried to modify this code cut-off but I could not.
else format.html { render action: "new" } format.json { render json: @upload.errors, status: :unprocessable_entity } end
I have following validations and I want json to write when an error occured, so something like this:
else format.html { render action: "new" } format.json { render json: @upload.errors, status: :unprocessable_entity, error:"Error!" } end
(it doenst work) and I need a specification of an error, that is written in a validation :message
my validations:
validates_uniqueness_of :upload_file_name, :message => "File with this name is already in the database"
validates :upload_file_size, :inclusion => {:in =>10.megabytes..20.megabytes}, :message =>"Too big or too small"
def to_jq_upload { "name" => read_attribute(:upload_file_name), "size" => read_attribute(:upload_file_size), "url" => upload.url(:original), "delete_url" => upload_path(self), "delete_type" => "DELETE" } end
end
Thanks in advanced
