I have installed the carrierwave gem.
my model is
class Rating < ActiveRecord::Base
attr_accessible :pic_url, :rating
mount_uploader :pic_url , ImageUploader
end
and my view for is
<%= form_for #rating, :html => {:multipart=>true} do |f| %>
<div class="field">
<%= f.file_field :pic_url %>
</div>
<div class="field">
<%= f.label :remote_pic_url_url, 'or image url' %>
<br/>
<%= f.text_field :remote_pic_url_url %>
</div>
<div class="actions">
<%= f.submit 'Upload Picture', :class => 'btn btn-primary' %>
</div>
<% end %>
I get an error msg Can't mass-assign protected attributes: remote_pic_url_url
when I remove the optional pic url field , then It works.
Just add remote_file_url to attr_accessible.

I seem to be stuck on a Ruby on Rails tutorial. I keep getting the error that is in the title of this post, which is:
Routing Error No route matches[POST]"/contacts/new"
app/views/contacts/new.html.erb
<div class="container">
<div class="rpw">
<h3 class="text-center">Contact Us</h3>
<div class="col-md-4 col-md-offset-4">
<%= flash[:notice] %>
<div class="well">
<%= form_for "/contacts" do |f| %>
<div class="form-group">
<%= f.label :name %>
<%= f.text_field :name, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :email %>
<%= f.text_field :email, class: 'form-control' %>
</div>
<div class="form-group">
<%= f.label :comments %>
<%= f.text_area :comments, class: 'form-control' %>
</div>
<%= f.submit 'Submit', class: 'btn btn-success' %>
<% end %>
</div>
</div>
</div>
routes.rb
Rails.application.routes.draw do
root to: 'pages#home'
get 'about', to: 'pages#about'
resources :contacts
end
contacts_controller.rb
class ContactsController < ApplicationController
def new
#contact = Contact.new
end
def create
#contact = Contact.new(contact_params)
if #contact.save
redirect_to new_contact_path, notice: "Message sent."
else
redirect_to new_contact_path, notice: "Error occured"
end
end
private
def contact_params
params.require(:contact).permit(:name, :email, :comments)
end
end
contact.rb
class Contact < ActiveRecord::Base
end
I am unsure where I am going wrong. Please help me. I have been trying to fix this for a few days now.
In new.html.erb
try changing
<%= form_for "/contacts" do |f| %>
to
<%= form_for #contact do |f| %>
I get this when I visit a user's profile page. so localhost:3000/users/1 for example...
I get it here in line 1
1: <%= form_for(#micropost) do |f| %>
2: <%= render 'shared/error_messages', object: f.object %>
3: <div class="field no-indent">
4: <%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
so then I have two micropost forms one is here
<%= form_for(#micropost, :html => { :id => "sale" }) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= hidden_field_tag 'micropost[kind]', "sale" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
and another one is here
<%= form_for(#micropost) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= hidden_field_tag 'micropost[kind]', "purchase" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
Here is my routes.
SampleApp::Application.routes.draw do
resources :users do
resources :comments
member do
get :following, :followers
end
end
resources :sessions, only: [:new, :create, :destroy]
resources :microposts, only: [:create, :destroy] do
resources :comments
resources :kind
end
resources :relationships, only: [:create, :destroy]
root to: 'static_pages#home'
match '/signup', to: 'users#new'
match '/signin', to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete
match '/help', to: 'static_pages#help'
match '/about', to: 'static_pages#about'
match '/contact', to: 'static_pages#contact'
and here is the code for the page itself (users show)
<section>
<%= render 'shared/user_info' %>
</section>
<section>
<div id= "purchases">
<%= render 'shared/micropost_form_purchase' %>
</div>
<div id="sales">
<%= render 'shared/micropost_form_sale' %>
</div>
</section>
<% provide(:title, #user.name) %>
<div class="row">
<aside class="span4">
<section>
<h1>
<%= gravatar_for #user %>
<%= #user.name %>
</h1>
</section>
</aside>
<div class="span8">
<% if #user.microposts.any? %>
<h3>Purchases I am interested in (<%= #user.microposts.count %>)</h3>
<ol class="microposts">
<%= render #microposts %>
</ol>
<%= will_paginate #microposts %>
<% end %>
</div>
</div>
also I dont understand how you can pass an empty object into form for? Isn't the whole point of the form to create the object?
According to the article which I stumbled upon today it may be that the object you are passing to form_for (#micropost in this case) is nil or empty.
Here's the mentioned article: http://schneems.com/post/31460949407/raise-hell-better-programming-through-error-messages
How to send data in database and show in needed part by using json format in ruby on rails3?
my form is like this
<%= 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 :name %><br />
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.text_field :email %>
</div>
<div class="field">
<%= f.label :login %><br />
<%= f.text_field :login %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
In the controller:
def show
#user = User.find(params[:user_id]
respond_to do |format|
format.json { :render => #user }
end
end
You can customise the JSON output by overriding the as_json in the User model:
def as_json(options=false)
self.include_root_in_json = false
options = (options || {}).reverse_merge(
:except => [:updated_at, :created_at, :id],
:include => :some_association
)
super(options)
end
I've had this issue for a few days and looked over every tutorial and stack overflow. I cannot seem to resolve. I can't seem to use nested attributes that work. I get an error with this form view.
**Form View**
<%= form_for #trip, :html => { :class => 'form-horizontal' } do |f| %>
<div class="control-group">
<%= f.label :start, :class => 'control-label' %>
<div class="controls">
<%= f.text_field :start, :class => 'text_field' %>
</div>
<div class="control-group">
<%= f.label :end, :class => 'control-label' %>
<div class="controls">
<%= f.text_field :end, :class => 'text_field' %>
</div>
<div class="control-group">
<% f.fields_for :driver do |d| -%>
<%= d.label :driver, :class => 'control-label' %>
<div class="controls">
<%= d.text_field :driver, :class => 'text_field' %>
</div>
Model:
class Trip < ActiveRecord::Base
attr_accessible :end, :start
belongs_to :driver
belongs_to :customer
accepts_nested_attributes_for :driver
end
class Driver < ActiveRecord::Base
attr_accessible :name
has_many :trips
end
As you said you need closing end tag.
If you have the "Can't mass-assing procteted attributes: drivers" error you must declare "attr_accessible" on :drivers_attributes at the trip model.
I load my custom view with this config in devise.rb
config.scoped_views = true
and then this is my app/views/users/sessions/new.html.erb
<div class="container">
<div id="login">
<%= devise_error_messages! %>
<%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name)) do |f| %>
<div class="login">
<li><%= f.label :email %> <%= f.text_field :email %></li>
<li><%= f.label :password %> <%= f.password_field :password %></li>
</div><!-- login -->
<div class="reset">
<%= f.input :email, :required => false, :autofocus => true %>
<%= f.input :password, :required => false %>
<%= f.input :remember_me, :as => :boolean if devise_mapping.rememberable? %>
</div>
<div class="login">
<%= f.button :submit, "Sign in" %>
</div>
<% end %>
<%= render "links" %>
</div><!-- login -->
</div><!-- container -->
When I submit it just goes back to the page.
When I disable scoped.views it logs in fine.
I forgot you uncomment this line
config.default_scope = :user
