Why does rails form working without adding csrf token - ruby-on-rails

I have a simple form
<form accept-charset="UTF-8" action="/users" method="post">
<label for="username">Username:</label>
<input type="text" id="username" name="user[username]">
<br>
<label for="email">Email:</label>
<input type="text" id="email" name="user[email]">
<br>
<label for="password">Password:</label>
<input type="password" id="password" name="user[password]">
<input type="submit" value="Submit">
</form>
And a controller
def create
#user = User.new(user_params)
if #user.save
redirect_to new_user_path
else
render :new, status: :unprocessable_entity
end
end
private
def user_params
params.require(:user).permit(:username, :email, :password)
end
Params which I get
#<ActionController::Parameters {"user"=>{"username"=>"username", "email"=>"email", "password"=>"password"}, "controller"=>"users", "action"=>"create"} permitted: false>
I don't add a csrf token in html form but it work correctly. Why is csrf token is not required?

Form validation in ruby on rails

I have built a sign up page in ruby on rails. I want to validate this sign up form. For example - if user left any section blank, the form will show an error message. It will also check whether the given email is unique. How can I do this by not changing my form?
#This my logins_controller.rb file
class LoginsController < ApplicationController
skip_before_action :verify_authenticity_token
def index
#subscriber=Subscriber.new()
end
def sign_up
subscriberNew = Subscriber.new
subscriberNew.name = params[:name]
subscriberNew.cus_user_name = params[:user_name]
subscriberNew.cus_password = params[:password]
subscriberNew.cus_email = params[:email]
result = subscriberNew.save
respond_to do |format|
msg = { :status => "ok", :message => "Success!" }
format.json { render :json => msg }
end
end
def validate_signup
#what should i write here?
end
end
and this is my sign up form
<div class="container">
<div class="shadow-lg p-3 mb-5 bg-white rounded view-card">
<h4 class="card-title">
<a href="/product_types">
<i class="material-icons">
arrow_back_ios
</i></a></h4>
<form id="signup_form" method="post" action="/sign-up">
<p class="h4 mb-4">Register to Binimoy</p>
<label for="name">Name</label>
<input type="text" name="name" id="name" class="form-control mb-4" placeholder="Name">
<label for="email">Email</label>
<input type="email" name="email" id="email" class="form-control mb-4" placeholder="Email">
<label for="phone">Phone</label>
<input type="text" name="phone" id="phone" class="form-control mb-4" placeholder="Phone">
<label for="name">Password</label>
<input type="password" name="password" id="password" class="form-control mb-4" placeholder="Password">
<div class="form-row mb-4">
<div class="col">
<button class="btn btn-default my-4 btn-block" type="reset">Reset</button>
</div>
<div class="col">
<button type="button" class="btn btn-info my-4 btn-block" id="submitAnchor">Submit</button>
</div>
</div>
</form>
</div>
First, use Rails helpers in your views and write your form as documented here.
<%= form_with url: sign_up_path do |form| %>
<%= form.label :email %>
<%= form.text_field :email %>
...
<%= form.submit %>
<% end %>
Second, use validations in your Subscriber model as documented here.
validates :email, presence: true, uniqueness: true
...
Hope it helps ;)
Rails is an framework with an strong opinion how to do things. You are doing things not the Rails way and this will make it more complicated.
If you really do not want to change your form (which is strongly advice against)
Add validations, check the return value of save and send back some error message
In your model:
validates :email, presence: true, uniqueness: true
In your controller:
if subscriber.save
render json: {status: "ok", message: "success"}
else
render json: {status: "nok", message: "something went wrong"}
end
Probably you should get rid of the status property and use the HTTP status code for this (sending back 201 (created) and 422 (unprocessble entity) responses instead)
Some other recommendatations to make your code more readable:
Follow the Rails conventions (use a form builder, it simplifies the assignment of form params to the model
Use Ruby naming conventions:
subscriberNew
should be
subscriber_new
since Ruby uses camel_case
but actually there is no need for the new suffix, so subscriber is enough
Use two spaces for identation
Don't abbreviate variables (cus_username, ...) and don't prefix when there is no need

rails adding to database

I am attempting to add product information to a rails sqlite database through a form. I can get users to be added but not the products for the store. This is the form.
<form action='/products/create' method="post">
<input type="hidden" name="authenticity_token" value="<%= form_authenticity_token %>">
<label>Name:
<input type="text" name="product">
</label>
<label>Amount:
<input type="number" name="amount">
</label>
<center><input type="submit" value="Sell"></center>
</form>
It does not throw an error but it does not save to db either.
Products_controller is
def create
#products = Product.new(name: params[:name], amount: params[:amount])
if #products.valid?
#products.save
flash[:message] = "New product added"
redirect_to "/users"
else
flash[:errors] = #products.errors.full_messages
redirect_to "/products"
end
I figured it out. The problem was this line.
<input type="text" name="name">
In my database product is defined as name and amount. Product does not have a product field.

Ruby on Rails param is missing or the value is empty without using a model

In my contact.html, I have this code
<div class="form">
<form name="email-form" method="POST">
<label class="field-label" for="name">Name:</label>
<input class="w-input text-field-2" id="name" type="text" name="name" data-name="Name" required="required">
<label class="field-label" for="Email">Email:</label>
<input class="w-input text-field-2" id="email" type="email" name="email" data-name="Email" required="required">
<label class="field-label" for="Subject">Subject:</label>
<input class="w-input text-field-2" id="subject" type="text" name="subject" data-name="Subject">
<label class="field-label" for="Content">Text Message:</label>
<textarea class="w-input text-field-2 area" id="content" name="content" data-name="Text Area" required="required"></textarea>
<div>
<input class="w-button button" type="submit" value="Submit Message" data-wait="Please wait...">
</div>
</form>
</div>
This is under my controller
def contact
end
def send_mail
MessageMailer.new_message(contact_params).deliver
redirect_to contact_path, notice: 'Your messages has been sent.'
end
private
def contact_params
params.require(:contact).permit(:name, :email, :subject, :content)
end
under mailers/message_mailer.rb
class MessageMailer < ActionMailer::Base
default from: "sys.questdentalusa#gmail.com"
default to: "questdentalusa#gmail.com"
def new_message(contact)
#contact = contact
mail subject: #contact.subject
end
end
and under my new_message.text.erb is this code
Name: <%= #contact.name %>
Email: <%= #contact.email %>
Message: <%= #contact.content %>
I am to send an email consisting user's name, email and message which is inputed and NOT saved in the database. When I pass the four parameters like this
def send_mail
MessageMailer.new_message(:name, :email, :subject, :content).deliver
redirect_to contact_path, notice: 'Your messages has been sent.'
end
it worked just fine but i was told to use only one parameter, seems like group the four parameters: name, email, subject, content as one (contact)
When I typed the info and hit the submit button, I get this error message
param is missing or the value is empty: contact
I presume that what caused this error is because my def contact is empty. So I added contact.new and #contact=contact.new and MessageMailer.new but this error occurs NoMethodError
How can I possibly fix this? What should I write under my def contact ?
Your controller code is correct. You don't need Contact.new or something. The problem is with your <form>. What ends up in params depends on your form and in your form you don't have contact.
Instead of:
<input type="text" name="subject">
You have to do something like this:
<input type="text" name="contact[subject]">
And that for all the fields on your contact form.
Another option would be to use Rails' form helpers.
contact[] is missing in your form, see below correct one:
<div class="form">
<form name="email-form" method="POST">
<label class="field-label" for="name">Name:</label>
<input class="w-input text-field-2" id="name" type="text" name="contact[name]" data-name="Name" required="required">
<label class="field-label" for="Email">Email:</label>
<input class="w-input text-field-2" id="email" type="email" name="contact[email]" data-name="Email" required="required">
<label class="field-label" for="Subject">Subject:</label>
<input class="w-input text-field-2" id="subject" type="text" name="contact[subject]" data-name="Subject">
<label class="field-label" for="Content">Text Message:</label>
<textarea class="w-input text-field-2 area" id="content" name="contact[content]" data-name="Text Area" required="required"></textarea>
<div>
<input class="w-button button" type="submit" value="Submit Message" data-wait="Please wait...">
</div>
</form>
</div>

routing form submission to different controller

problem: I have a form but the submit button doesn't do anything.
i instantiate the class the form is for in the employee_controller controller.
def employee
#body_class = "employee membership"
#employee_contact_form = CorporateContactForm.new
end
I create the form in the page the above controller action serves
= simple_form_for [#employee_contact_form] do |f|
= f.input :firstname
= f.button :submit
In my routes I set the resources for the contact forms
resources :corporate_contact_forms
I then have a controller that serves the form
class CorporateContactFormsController < ApplicationController
def create
raise
end
I am aware there is no code in the corporatecontactcontroller, but the submit button should at least fire to an error. It doesn't do anything.
This feels like such a simple problem, and surely it is.
What am I missing?
update
html output
<form>
<form accept-charset="UTF-8" action="/corporate_contact_forms" class="simple_form new_corporate_contact_form" id="new_corporate_contact_form" method="post"><div style="display:none"><input name="utf8" type="hidden" value="✓" /><input name="authenticity_token" type="hidden" value="7iMwWQOuyzV3jJt4jTtr9MGvI129hPaG+m+Pe2D3YyM=" /></div> <div class="input string optional corporate_contact_form_firstname"><label class="string optional" for="corporate_contact_form_firstname">Firstname</label><input class="string optional" id="corporate_contact_form_firstname" maxlength="255" name="corporate_contact_form[firstname]" size="255" type="text" /></div>
<input class="button" name="commit" type="submit" value="Create Corporate contact form" />
</form>
</form>
According to the documetation (http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_for), you can do something like this to force the form to go to CorporateContactFormsController#create
<%= simple_form_for #employee_contact_form, url: corporate_contact_forms_path, method: :post do |f| %>
# awesome code...
<% end %>
Also I'm not sure if the f.button :submit has something to do, the default for submitting is f.submit

How to post html form data to controller using ruby on rails 3.1

I am using ruby on rails 3.1. And am trying to post html form data to controller for saving the record in database. But I am getting routing error like this 'No route matches [POST] first/save' .But when I tried to run this link in address bar like '127.0.0.1:3000/first/save' it is working fine. Can any one please tell me where am doing wrong.
My routes are like:
Rails.application.routes.draw do
root 'first#hello'
get 'first/save'
end
And my html form is like:
<form accept-charset="UTF-8" method='post' action='/first/save'>
<label for='S.No'>S.No</label>
<input type="text" name="s_no" placeholder='Enter s. no.'>
<label for='name'>Name</label>
<input type="text" name='name' placeholder='Enter your name'> <br>
<label for='seller_id'>Seller ID</label>
<input type="text" name='seller_id' placeholder='Enter your seller ID'> <br>
<label for='email'>Email</label>
<input type="email" name='email' placeholder='Enter your email'> <br>
<label for='img_url'>Image</label>
<input type='text' name='img_url' placeholder='Enter your image url'> <br>
<input type="submit" name='save' value='Save'>
</form>
And here is my controller:
class FirstController < ApplicationController
def save
#name = params[:name]
#email = params[:email]
#seller_id = params[:seller_id]
#img_url = params[:img_url]
#s_no = params[:s_no]
end
end
If you want to do POST requests, instead of
get 'first/save'
you should have
post 'first/save'
