Question

I have establish a Crud interface with devise below my code, the problem that I am running into is that When I try to create a user a get the following errors. I can't edit either. Please help.
"2 errors prohibited this user from being saved:
Email can't be blank
Password can't be blank"
of course I have been entering all of the information inclduding email and password. I follow the documentation from devise and have read some of this site Devise topics no such problem reported.
Controller:
class UsersController < ApplicationController
before_filter :authenticate_user!
before_action :authorized_user
# GET /users
# GET /users.json
def index
#users = User.all
# respond_to do |format|
# format.html index.html.erb
# format.json { render :json => #users }
end
# GET /users/1
# GET /users/1.json
def show
#user = User.find(params[:id])
# respond_to do |format|
# format.html show.html.erb
# format.json { render :json => #user }
end
# GET /users/new
# GET /users/new.json
def new
#user = User.new
# respond_to do |format|
# format.html new.html.erb
# format.json { render :json => #user }
end
# GET /users/1/edit
def edit
#user = User.find(params[:id])
end
# POST /users
# POST /users.json
def create
#user = User.new(params[:user_params])
respond_to do |format|
if #user.save
format.html { redirect_to #user, :notice => 'User was successfully created.' }
format.json { render :json => #user, :status => :created, :location => #user }
else
format.html { render :action => "new" }
format.json { render :json => #user.errors, :status => :unprocessable_entity }
end
end
end
# PUT /users/1
# PUT /users/1.json
def update
if params[:user][:password].blank?
params[:user].delete(:password)
params[:user].delete(:password_confirmation)
end
#user = User.find(params[:id])
respond_to do |format|
if #user.update_attributes(params[:user_params])
format.html { redirect_to #user, :notice => 'User was successfully updated.' }
format.json { head :ok }
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 = User.find(params[:id])
#user.destroy
respond_to do |format|
format.html { redirect_to users_url }
format.json { head :ok }
end
end
private
def user_params
params.require(:user).permit(:username, :name, :lastname, :email, :password, :password_confirmation, :role_id)
end
def authorized_user
if current_user.role.name == "admin"
else
redirect_to :root, notice: "Not authorized" if #current_user.role.name == 'user' or nil?
end
end
end
Here is my form:
<%= form_for(#user) do |f| %>
<% if #user.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#user.errors.count, "error") %> prohibited this user from being saved:</h2>
<ul>
<% #user.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :username %><br />
<%= f.text_field :username, autofocus: true %>
</div>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name, autofocus: true %>
</div>
<div class="field">
<%= f.label :lastname %><br />
<%= f.text_field :lastname, autofocus: true %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<div class="field">
<%= f.label :password %>
<% if #minimum_password_length %>
<em>(<%= #minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :role_id %><br />
<%= f.collection_select :role_id, Role.all, :id, :name_role_select %>
</div>
<div class="actions">
<%= f.submit "Sign up", class: 'button' %>
</div>

Answer 1

You aren't properly using your user_params.
Instead of this in your create action:
User.new(params[:user_params])
You need this, which calls your user_params method which is defined in your controller:
User.new(user_params)
Your original way is looking for params passed in from your request called 'user_params'(which doesn't exist).
Similarly, for your update action you need:
if #user.update_attributes(user_params)
#etc...
