Cant add date in rails form - ruby-on-rails

Question

I want to add the date in rails form. For example
def create
#land=current_user.lands.build(land_params)
if #land.save
session[:land_id]=#land.id
flash[:success]="Success"
redirect_to lands_path
else
flash[:error]="Fail!!"
render 'new'
end
end
schema.rb
create_table "lands", force: :cascade do |t|
t.date "DateStart"
t.date "DateEnd"
end
new.html.erb
<%= form_for #land do |f| %>
<p>Information</p>
<%= f.label :Start %><br />
<%= f.date_select :DateStart, :default => #DateStart, :order => [:month, :day, :year] %>
<%= f.label :End %><br />
<%= f.date_select :DateEnd,:default => #DateEnd,:order => [:month, :day, :year]%>
<% end %>
show.html.erb
<p>Start : <%= #land.DateEnd %></p>
<p>End : <%= #land.DateEnd %></p>
Land.controller
def show
#land= Land.find(params[:id])
end
But nothing is printed out in my show.html.erb. When I check database my DateStart and DateEnd is nil. I don't know what wrong. Can you give me some advice? Thanks

Answer 1

You can follow like below
def create
#land= Land.new(land_params)
#land.user = current_user
if #land.save
flash[:success] = 'Land was successfully created.'
redirect_to lands_path #=> or anything
else
flash[:error] = 'Land was not created successfully .'
redirect_to lands_path #=> or anything
end
end
I think that's work
You make sure add this before_action :authenticate_user! on your controller header, that's cannot access user without authentication
Hope to help

You can follow my answers -
Method - 1. No association with User and Land model.
lands_controller.rb file look like -
class LandsController < ApplicationController
def new
#DateStart = Date.today
#DateEnd = Date.today + 2.days
#land = Land.new
end
def create
#land = Land.new(land_params)
if #land.save
session[:land_id] = #land.id
flash[:success]= "Success"
redirect_to lands_path
else
flash[:error] = "Fail!!"
render 'new'
end
end
def show
#land= Land.find(params[:id])
end
def land_params
params.require(:land).permit(:DateStart, :DateEnd)
end
end
Database Schema file look like - (schema.rb)
create_table "lands", force: :cascade do |t|
t.date "DateStart"
t.date "DateEnd"
end
Lands controller new action view file - (app/views/lands/new.html.erb)
<%= form_for #land do |f| %>
<p>Information</p>
<%= f.label :Start %><br />
<%= f.date_select :DateStart, :default => #DateStart, :order => [:month, :day, :year] %>
<%= f.label :End %><br />
<%= f.date_select :DateEnd,:default => #DateEnd,:order => [:month, :day, :year]%>
<%= f.submit "Submit" %>
<% end %>
Lands view page (app/views/lands/show.html.erb)
<p>Start : <%= #land.DateEnd %></p>
<p>End : <%= #land.DateEnd %></p>
Method - 2. Association with User and Land model.
lands_controller.rb file look like - (app/controllers/lands_controller.rb)
class LandsController < ApplicationController
before_action :authenticate_user!
def new
#DateStart = Date.today
#DateEnd = Date.today + 2.days
#land = current_user.lands.build
end
def create
#land = current_user.lands.build(land_params)
if #land.save
session[:land_id] = #land.id
flash[:success]= "Success"
redirect_to lands_path
else
flash[:error] = "Fail!!"
render 'new'
end
end
def show
#land= Land.find(params[:id])
end
def land_params
params.require(:land).permit(:DateStart, :DateEnd)
end
end
Database Schema file look like - (schema.rb)
create_table "lands", force: :cascade do |t|
t.date "DateStart"
t.date "DateEnd"
t.index ["user_id"], name: "index_rooms_on_user_id"
end
create_table "users", force: :cascade do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.index ["email"], name: "index_users_on_email", unique: true
t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
User model look like - (app/models/user.rb)
class User < ApplicationRecord
has_many :lands
end
Land model look like - (app/models/land.rb)
class Land < ApplicationRecord
belongs_to :user
end
Lands controller new action view file - (app/views/lands/new.html.erb)
<%= form_for #land do |f| %>
<p>Information</p>
<%= f.label :Start %><br />
<%= f.date_select :DateStart, :default => #DateStart, :order => [:month, :day, :year] %>
<%= f.label :End %><br />
<%= f.date_select :DateEnd,:default => #DateEnd,:order => [:month, :day, :year]%>
<%= f.submit "Submit" %>
<% end %>
Lands view page (app/views/lands/show.html.erb)
<p>Start : <%= #land.DateEnd %></p>
<p>End : <%= #land.DateEnd %></p>
I hope it should work.
