Rails 4: undefined method `permit' for "xxxx xxxx":String - forms

I have a search model that I hope to use in conjuction with sunspot to handle all searches across different models. I'm stuck before I even have gotne started.
Here is the form...that appears in the header of all the web pages on my site.
<%= simple_form_for #search, :url => searches_path, :method => :post do %>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag "Search", class: "btn btn-primary" %>
<% end %>
In my searches_controller
def search_params
params.require(:search).permit(:search)
end
In my Search.rb
attr_accessor :search
When I plug in my name into it I get this error
undefined method `permit' for "simon walsh":String
Parameters:
{"utf8"=>"✓",
"authenticity_token"=>"1Tez0pnMILEciLR6j+li+qSeO4NYBj3XsB6dYG07RymsiNUNSAGI5ztpMiD4JNAtTnqwJYdHTpPBRqGduWHjBw==",
"search"=>"simon walsh",
"commit"=>"Search"}
I am confused. This is clearly a simple error with the way I am posting the params. Any help?

Use this:
def search_params
params.require(:search).permit!
end
Instead of this:
def search_params
params.require(:search).permit(:search)
end
This issue may occur because of string parameter in params["search"], while in controller you are using .permit(:search), or maybe you have an attribute and model name that are the same.

How do I pass form variables from views to controllers in Rails 4?

I'm trying to accept telephone numbers in a simple form and I can't seem to get it to pass the variable through to the controller. The code I have so far is:
view on /users/new.erb:
<%= form_for #user do |f| %>
<%= field_set_tag do %>
<p><%= f.label :phone %><br>
<%= f.text_field :phone%>
<%= f.submit "Submit" %>
<% end %>
<% end %>
and in the controller I have:
def new
#user = User.new
end
def create
#user = User.new(params[:new])
phone = #user.phone
end
Any help would be greatly appreciated. Thanks.
There are a few problems with your code. When you write:
<%= form_for #user %>
All the form fields are sent to the controller in the form of a hash with "user" as the root. Just like
{"user": {"phone": "ENTERED PHONE NUMBER"}}
To access these fields in the controller you need to use the following method:
#phone_number = params[:user][:phone]
One More Important Thing
For security purposes rails does uses Strong Parameters. It means that you can't use the form parameters directly in Active Model for mass assignment like this:
#user = User.new(params[:user])
You need to permit all the fields explicitly for mass assignment. This can be achieved as follows.
def create
#user = User.new(params_user)
#user.save
end
private
def params_user
params.require(:user).permit(:phone)
end
params[:new] just passes the parameter :new to your #user object, but there is no params[:new] parameter because it is not defined in your form. params[:phone] should be passed to '#user' just params if you want all available params that were submitted.
Try
#user = User.new(params) #instead of #user = User.new(params[:new])
#user.phone

Rails: how to save few elements from string

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])

Rails Tutorial 3.2 Chapter 8 error: NoMethodError in SessionsController#create

I'm going through the rails tutorial and my login page is throwing an exception after exercise 8.1.5 when I click the login button with no email or pw entered:
http://ruby.railstutorial.org/chapters/sign-in-sign-out#sec-rendering_with_a_flash_message
Error:
NoMethodError in SessionsController#create
undefined method `[]' for nil:NilClass
app/controllers/sessions_controller.rb:7:in `create'
SessionsController matches the final code exactly for the Create method
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:session][:email].downcase) #line 7
if user && User.authenticate(params[:session][:password])
#will fill this in later
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
end
def destroy
end
end
I did change the button label to Log in instead of "Sign in" as that is too confusing with "Sign up", but I didn't think that would create the problem. sessions\new.html.erb
<% provide(:title, "Log in") %>
<h1>Log in</h1>
<div class="row">
<div class="span6 offset3">
<%= form_for(:sesssion, url: sessions_path) do |f| %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.submit "Log in", class: "btn btn-large btn-primary" %>
<% end %>
<p>New user? <%= link_to "Sign up now!", signup_path %></p>
</div>
</div>
This post hints that I need a method in my user model, but adding that didn't help:
NoMethodError in SessionsController#create
I tried adding this to user.rb, but it didn't help
results from find_by_email executed in function differs from console:
def self.authenticate(email, submitted_password)
user = find_by_email(email)
return user.nil? ? nil : user
end
Any ideas would be greatly appreciated!
I've looked at the example from the book and your code and I noticed this line
if user && User.authenticate(params[:session][:password])
your User.authenticate should be lowercased to user.authenticate. Revert back to your original code.
I have just had the same problem and found that in fact i needed [:sessions] with an s on the end!
So line reads
if user && User.authenticate(params[:sessions][:password])
Hope this helps someone in the future!
I had the same problem after doing exercise 1 in chapter 8 where I replaced the use of form_for with form_tag. This resulted in the name attributes in the generated input form fields changing from name="session[email]" and name="session[password]" to name="email" and name="password". Subsequently, I needed to access the params using params[:email] and params[:password] instead of params[:session][:email] and params[:session][:password].
My new Sessions controller looks like this:
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email].downcase)
if user && user.authenticate(params[:password])
sign_in user
redirect_to user
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
end
def destroy
sign_out
redirect_to root_url
end
end
This solved the problem for me. Hope this is helpful to someone else.
In this section from the tutorial chapter 8, all instances of [:session] should be [:sessions]. Hope that helps.
class SessionsController < ApplicationController
.
.
.
def create
user = User.find_by(email: params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_to user
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
end
.
.
.
end
Could you confirm the word 'session' in app/view/session/new.html.erb spelling correct?
I see you wrote:
form_for(:sesssion, url: sessions_path) do |f|
But in app/controllers/sessions_controller.rb, you wrote:
user = User.find_by_email(params[:session][:email].downcase) #line 7
They must be the same.

Save the file manually using paperclip from the params, without scaffold

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".

searchresult usin sphinx

i am using sphinx beta and thinking-sphinx to perform search functionality..the search i
wann should search for the word i entered in the database.which is populated with data already.
so in my application Mydoc,i got articlesmodel and controller.. articles is db is populated with data.
i wann to search for the data in articles..so far i ve done with following things but not getting the search result
=> created new search controller
def index
#articles = Article.search params[:search]
end
=> articles.rb(model)
define_index do
indexes name, :sortable => true
indexes description
indexes title, :sortable => true
end
def self.search(search)
ThinkingSphinx::Search
end
=> searches/index.html.erb
<%= form_tag do %>
<p>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag "search", :name => nil %>
</p>
<% end %>
BUT WEN I CLICK ON THE SEARCH BUTTON ITS ASKING FOR CREATEACTION ?????
PLEASE COULD U HELP TO GET SEARCH RESULT
Your form is making a POST request to your SearchController, and that is interpreted as a call to the create action. Try using a GET request instead with your form - something like this:
<%= form_tag '', :method => :get do %>
