Rspec ruby rails -


i'm trying create action set properly.

i keep getting error: argumenterror: unknown keyword: topic

here testing:

require 'rails_helper'  rspec.describe topicscontroller, type: :controller  let(:my_topic) { topic.create!(name: randomdata.random_sentence, description: randomdata.random_paragraph)} describe "post create" "increases number of topics 1"   expect{ post :create, {topic: {name: randomdata.random_sentence, description: randomdata.random_paragraph}}}.to change(topic,:count).by(1) end  "assigns topic.last @topic"   post :create, { topic: {name: randomdata.random_sentence, description: randomdata.random_paragraph}}   expect(assigns(:topic)).to eq topic.last end  "redirects new topic"   post :create, {topic: {name: randomdata.random_sentence, description: randomdata.random_paragraph}}   expect(response).to redirect_to topic.last end end

here controller:

  def create @topic = topic.new @topic.name = params[:topic][:name] @topic.description = params[:topic][:description] @topic.public = params[:topic][:public]  if @topic.save   redirect_to @topic, notice: "topic saved successfully." else   flash.now[:alert] = "error creating topic.  please try again"   render :new end end

i'm trying figure out i'm missing causing error i've been staring @ hours , have tried edit multiple times no avail. can't figure out. rest of project i've been working on has been okay cannot figure out why can't word topic convert successfully. taking look.

the problem post method takes keyword arguments second argument.

if need specify params, params keyword should used:

post :create, params: { topic: { name: ..., description: ... } }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
