No entry has been saved to database in ruby on rails? - ruby-on-rails

Question

I have created a table name tenants which have following column
class CreateTenants < ActiveRecord::Migration
def change
create_table :tenants do |t|
t.text :company_name
t.text :work_area
t.text :second_pref
t.text :third_pref
t.integer :who_are_you
t.integer :number_of_bedroom
t.text :other_specs
t.string :budget
t.string :name
t.string :email
t.string :contact_number
t.timestamps null: false
end
end
end
And i am entering the data into in table by following form
<%= form_for Tenant.new do |val| %>
<%= val.label :company_name, "Company Name" %>
<%= val.text_field :company_name, class: 'form-control' %>
<%= val.label :work_area, "Work Area" %>
<%= val.text_field :work_area, class: 'form-control' %>
<%= val.label :second_pref, "Second Preference" %>
<%= val.text_field :second_pref, class: 'form-control' %>
<%= val.label :third_pref, "Third Preference" %>
<%= val.text_field :third_pref, class: 'form-control' %>
<%= val.label :who_are_you, "Are you Family/Bachelor?" %>
<%= val.text_field :who_are_you, class: 'form-control' %>
<%= val.label :number_of_bedroom, "Number of Bedroom" %>
<%= val.text_field :number_of_bedroom, class: 'form-control' %>
<%= val.label :other_specs, "Other Requirments" %>
<%= val.text_field :other_specs, class: 'form-control' %>
<%= val.label :budget, "Your Budget" %>
<%= val.text_field :budget, class: 'form-control' %>
<%= val.label :name, "Name" %>
<%= val.text_field :name, class: 'form-control' %>
<%= val.label :email, "Email" %>
<%= val.text_field :email, class: 'form-control' %>
<%= val.label :contact_number, "Contact Number" %>
<%= val.text_field :contact_number, class: 'form-control' %>
<%= val.submit "Submit", class: "btn btn-primary" %>
<% end %>
When i fill all the required filled and click submit, i see the following output in rails server log.

Unpermitted parameter: budget

Can anyone tell me, why this happening ?

Answer 1

It seems you are missing :budget in strong parameters of your tenants_controller.rb file. It should be something like this.
private
def tenant_params
params.require(:tenant).permit(:company_name,
:work_area,
:second_pref,
:third_pref,
:who_are_you,
:number_of_bedroom,
:other_specs,
:budget,
:name,
:email,
:contact_number)
end

Answer 2

Unpermitted parameter: budget
This is your error - it means you're passing parameters to your controller, but it cannot save them in your model.
The fix is to set the strong params method (as shravan40 suggested).
Since you're calling Tenant.new in your #new action, I would recommend using the following in your controller:
#app/controllers/tenants_controller.rb
class TenantsController < ApplicationController
def new
#tenant = Tenant.new
end
def create
#tenant = Tenant.new tenant_params
#tenant.save
end
private
def tenant_params
params.require(:tenant).permit(:company_name, :work_area, :second_pref, :third_pref, :who_are_you, :number_of_bedroom, :other_specs, :budget, :name, :email, :contact_number)
end
end
There's also something you can do to polish up your form...
<%= form_for #tenant do |val| %>
<% vals = [[:company_name],[:work_area],[:second_pref, "Second Preference"], [:third_pref, "Third Preference"],[:who_are_you, "Are you Family/Bachelor?"], [:number_of_bedroom], [:other_specs, "Other Requirements"],[:budget, "Your Budget"], [:name], [:email], [:contact_number]] %>
<% vals.each do |value| %>
<% value[1] ||= value[0].to_s.gsub("_", " ") %>
<%= val.label value[0], value[1] %>
<%= val.text_field value[0], class: 'form-control' %>
<% end %>
<%= val.submit "Submit", class: "btn btn-primary" %>
<% end %>
