    <p>I am a Ruby on Rails newbie, and am trying to put into practice some of the tutorials I have been following.</p> <p>I am currently trying to get a basic user signup working.</p> <p>When the signup form is completed and submitted, the Firstname and Lastname fields are blanked out and I get two error messages (I also get a failing error when running the cucumber tests):</p> <ul> <li>Firstname can't be blank</li> <li>Lastname can't be blank</li> </ul> <p>I think I have missed something fairly obvious with the authentication code, but can't spot what I have missed.</p> <p>All my code is on my <a href="https://github.com/nstoker/ScoutHut" rel="nofollow">github account</a></p> <h2>Controller</h2> <pre><code>class UsersController &lt; ApplicationController before_action :set_user, only: [:show, :edit, :update, :destroy] # GET /users # GET /users.json def index @users = User.all end # GET /users/1 # GET /users/1.json def show end # GET /users/new def new @user = User.new end # GET /users/1/edit def edit end # POST /users # POST /users.json def create @user = User.new(user_params) respond_to do |format| if @user.save format.html { redirect_to @user, notice: 'User was successfully created.' } format.json { render action: 'show', status: :created, location: @user } else format.html { render action: 'new' } format.json { render json: @user.errors, status: :unprocessable_entity } end end end # PATCH/PUT /users/1 # PATCH/PUT /users/1.json def update respond_to do |format| if @user.update(user_params) format.html { redirect_to @user, notice: 'User was successfully updated.' } format.json { head :no_content } else format.html { render action: 'edit' } format.json { render json: @user.errors, status: :unprocessable_entity } end end end # DELETE /users/1 # DELETE /users/1.json def destroy @user.destroy respond_to do |format| format.html { redirect_to users_url } format.json { head :no_content } end end private # Use callbacks to share common setup or constraints between actions. def set_user @user = User.find(params[:id]) end # Never trust parameters from the scary internet, only allow the white list through. def user_params params.require(:user).permit(:firstname, :middlename, :lastname, :email, :password, :password_confirmation) end end </code></pre> <h2>Model</h2> <pre><code>class User &lt; ActiveRecord::Base # Include default devise modules.

    1. COlooks like you're using devise authentication and you have registrable in your model however, i don't see correct setup of your form. The following assumes that you have set "@user" correctly. <%= form_for(@user) do |f| %> if you have followed the devise tutorial your new form should be showing(rake routes): new_user_registration GET /users/sign_up(.:format) devise/registrations#new

    3. COThe usual practice is to use ".html.erb" for naming template files which indicates Embedded Ruby (".erb") instead of 'just' Ruby (".rb")

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
