As my title of question.
I can't print value of var myArray. Plz help me. I am begin to nodejs, ejs.
index.js:
res.render('index',{
nickName: 'My Nick',
fullName: 'My Name',
myArray: [
myClass = 'nodeJs',
mySchool = 'Home School'
]
});
index.ejs
<div>My Nick is: <%= nickName %></div>
<div>My Name is: <%= fullName %></div>
<div>My Class is: <%= myArray['myClass'] %></div> // can't print
<div>My School is: <%= myArray['mySchool'] %></div> // can't print
<div>My Array is: <% myArray.forEach(function(value){ %>
<%= value %>
<% }) %>
Thanks!
to assign an array you can write like this
myArray: {
myClass: 'nodeJs',
mySchool: 'HomeSchool'
}
then on index.ejs view call it like this
<%= myArray.myClass %>
myArray: [
myClass = 'nodeJs',
mySchool = 'Home School'
]
should be
myArray: [
myClass: 'nodeJs',
mySchool: 'Home School'
]
myArray: [
myClass = 'nodeJs',
mySchool = 'Home School'
]
This is clearly not a JS code. Probably it should be like this:
myArray: {
myClass: 'nodeJs',
mySchool: 'HomeSchool'
}

Getting strange error in rails when saving a follower:
Error on Page after submitting follower form
I execute all of the commands in the followers#create method in the rails console and it works. But for some reason when I execute the form on the page, it does not seem to save the user then I get this error on the page. Any ideas? Not sure if it's got something to do with my routes, so I'll post them as well.
Routes.rb:
TwitterApp::Application.routes.draw do
get "followers/show"

I'm trying to allow users to sign in with either their username or their email address.
as per here: https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-sign-in-using-their-username-or-email-address
When ever I try to sign in with either the email or the login this is logged:

its weird the sql isn't checking for the username, so maybe the call on the user is wrong, but its exactly from the devise documentation.
I have read the following:
Adding Username to devise rails 4
Logging in with username using Devise with Rails 4
I also reviewed the warden code and the devise code to try and discover if I'm overriding the wrong method in the user.
Any ideas why it is not authenticating with username, when it does with email?
ApplicationController.rb
class ApplicationController < ActionController::Base
protect_from_forgery
before_filter :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation) }
devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :email, :password, :remember_me) }
# Need to add other user fields like gender etc.
devise_parameter_sanitizer.for(:account_update) {|u| u.permit(:email, :password, :password_confirmation, :current_password)}
end
end
User.rb
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable, :confirmable, :encryptable, :recoverable, :rememberable, :trackable, :validatable
attr_accessor :login # This is used to add the login for allowing user to sign in with both email or username
# Validations
validates :username, presence: true, length: {maximum: 255}, uniqueness: { case_sensitive: false }, format: { with: /\A[a-zA-Z0-9]*\z/, message: "may only contain letters and numbers." }
# Overwrite devise’s find_for_database_authentication method in user model
def self.find_first_by_auth_conditions(warden_conditions)
conditions = warden_conditions.dup
if login = conditions.delete(:username)
where(conditions).where(["lower(username) = :value OR lower(email) = :value", { :value => login.downcase }]).first
else
where(conditions).first
end
end

Devise.rb
config.secret_key = 'Omitted for security'
config.mailer_sender = 'Omitted for security'
config.case_insensitive_keys = [ :email ]
config.strip_whitespace_keys = [ :email ]
config.skip_session_storage = [:http_auth]
config.stretches = Rails.env.test? ? 1 : 10
config.reconfirmable = true
config.password_length = 8..128
config.reset_password_within = 6.hours
config.encryptor = :sha512
config.sign_out_via = :delete
You need to add
config.authentication_keys = [ :login ]
within devise.rb
Also if you want to use login as reset password or confirmation keys you should also add within the same file:
config.reset_password_keys = [ :login ]
config.confirmation_keys = [ :login ]
You also need to whitelist the login parameter within your application_controller. In the new.html view you have a login form, so you must accept the login parameter for the sign_in instead of the username and email parameters.
devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :password, :remember_me) }
I have rails form_tag helper to save data provided by do..each loop. This is my form:
<%= form_tag (customers_path) do |f| %>
< #contacts.each do |c|%>
<%= check_box_tag "accept[]", c %><%= c[:email] %>
<% end %>
<%= submit_tag ("Save") %>
<%end%>
This form saves the contacts whose checkbox is checked. Here is what, c has:
"accept"=>["{:id=>\"2f310f1d9b8f\",
:first_name=>\"San\",
:last_name=>\"Jori\",
:name=>\"Jori,San\",
:email=>\"abc#qwe.com\",
:gender=>nil,
:birthday=>nil,
:profile_picture=>nil,
:relation=>nil}"],
"commit"=>"Save"
I want to save only :name and :email from above hash.
This is my create action of controller:
if params[:accept].present?
params[:accept].each do |customer|
#customer = current_user.customers.new(:name => customer[:name], :email => customer[:email])
#customer.save
end
redirect_to customers_path
end
But it is giving error of :
no implicit conversion of Symbol into Integer
Can anyone tell me how to make it work?
Thank you!
Instead of using
#customer = current_user.customers.new(:name => customer[:name], :email => customer[:email])
Try
#customer = current_user.customers.build(:name => customer[:name], :email => customer[:email])
I am new to rails, I was working on paperclip gem and wanted to save the simple files, saved from paperclip.
I have the My model as follow :-
class UserAttachment < ActiveRecord::Base
attr_accessible :email, :user_id, :attached_file
has_attached_file :attached_file
validates_attachment_presence :attached_file
validates_attachment_size :attached_file, :less_than => 20.megabytes
end
My controller action where the form is called :-
class HomeController < ApplicationController
def index
#uattachment = UserAttachment.new
end
end
Index view code, where the form is located
<%= form_for #uattachment, :url => attachment_get_link_path, :html => { :method => :post, :id => 'attachment_form', :multipart => true }, :remote => true do |f| %>
<%= f.email_field :email, :value=>nil, :placeholder => "Enter your email here", :required => true %><br />
<%= f.file_field :attached_file %>
<%= f.submit "Submit" %>
<% end %>
I want to use some following kind of code to save the data :-
(Code below is not the correct code, it's an excitation to tell what I want to do in my application.)
#uattachment = UserAttachment.new
#uattachment = params[:user_attachment]
#uattachment.save
Params received are as follows :-
(rdb:6) pp params
{"utf8"=>"✓",
"authenticity_token"=>"dfjaskldjadslgjsoidruts48589034lsker=",
"user_attachment"=>
{"email"=>"testing#email.com",
"attached_file"=>
#<ActionDispatch::Http::UploadedFile:0x007fcb58682ba0
#content_type="image/jpeg",
#headers=
"Content-Disposition: form-data; name=\"user_attachment[attached_file]\"; filename=\"someimage.jpg\"\r\nContent-Type: image/jpeg\r\n",
#original_filename="800px-Kinnaur_Kailash.jpg",
#tempfile=#<File:/tmp/RackMultipart20121205-8432-1fc1kpi>>},
"commit"=>"Submit",
"controller"=>"attachment",
"action"=>"get_link"}
Got the catch, it was pretty simple, I checked it from the scaffolded assignment,
def index
#uattachment = UserAttachment.new(params[:user_attachment])
#uattachment.save
end
And you get the golden words in response "true".
I can't debug why I am getting an error:
class VendorsController < ApplicationController
def tag_cloud
#tags = Vendor.tag_counts_on(:tags)
end
I set this class as Taggable:
class Vendor < ActiveRecord::Base
acts_as_taggable_on :tags, :competitors
I include the TagsHelper:
module VendorsHelper
include TagsHelper
end
This is in my View:
<% tag_cloud(#tags, %w(css1 css2 css3 css4)) do |tag, css_class| %>
<%= link_to tag.name, { :action => :tag, :id => tag.name }, :class => css_class %>
<% end %>
This is the error that I get:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.empty?
Each instance of Vendor has at least one Tag.
Got it, I needed to add: #tags = Vendor.tag_counts_on(:tags) in the index controller.
