now i'm doing a grocery website. I trying to build an order form that can choose select supplier and outlet,so admin can create order by choosing which supplier and outlet, but now it come out error say unpermitted parameters.
Orders Controller
class OrdersController < ApplicationController
def supplier
#supplier = Supplier.find(params[:id])
end
def outlet
#outlet = Outlet.find(params[:id])
end
def index
#orders = Order.all
end
def show
#order = Order.find(params[:id])
end
def new
#order = Order.new
#supplier = Supplier.all
#outlet = Outlet.all
end
def create
#order = Order.new(order_params)
#supplier_id = Supplier.all
#outlet_id = Outlet.all
if #order.save
flash[:success] = "Succesful create!"
redirect_to #order
else
render 'new'
end
end
private
def order_params
params.require(:order).permit(:supplier_id,:grand_total, :order_date,
:delivery_date, :delivery_address, :outlet_id)
end
end
new.html.erb

The reason you're getting
Unpermitted parameters: :supplier, :outlet
is because you're not allowing :supplier and :outlet params but :supplier_id and :outlet_id in order_params
The Fix
Change this in your view new.html.erb
<%= f.label :supplier_id %>
<%= f.select(:supplier_id, Supplier.all.collect { |l| [ l.name, l.id] }, {class: "form-select"}) %>
<%= f.label :outlet_id %>
<%= f.select(:outlet_id, Outlet.all.collect { |l| [ l.name, l.id] }, {class: "form-select"}) %>
This should fix the issue by allowing the :supplier_id and :outlet_id params and assigning the object with proper values

issue is with your model file as pointed out by #Sergio in a comment.
#app/models/outlet_supplier.rb
class OutletSupplier < ApplicationRecord
belongs_to :outlet
belongs_to :supplier

end

I hope this will help you.

Hi as mentioned in request params, I can see that role_id you are passing in params as
Parameters:
params = {"authenticity_token"=>"[FILTERED]",“worker"=>{"name"=>"Daniel", "“email"=:“daniel#example.com", “phone_number"=:"Q134657891",“address"=>"Alor Setar", “password"=>"[FILTERED]", “role id"=>"1", “company _id"=:"2",“commit"=>"Create worker"}
#you can access the role ID as below:
params[:worker][:role_id]
But you are using it in the controller as
#worker_role = Role.find(params[:id])
#this should be as below:
#worker_role = Role.find(params[:worker][:role_id]).worker_roles.create(worker: #worker)
# OR
#if you are permitting role id
#worker_role = Role.find(worker_params[:role_id]).worker_roles.create(worker: #worker)
I am trying to create categories for my posts. To do so, I generated a new category model. Although I have associated the two models, I am still receiving this error:
ActiveRecord::UnknownAttributeError: unknown attribute 'category_id' for Post.
I have doublechecked the schema which does include category_id for the post table:
add_index "comments", ["post_id"], name: "index_comments_on_post_id"
create_table "posts", force: :cascade do |t|
t.string "title"
t.text "description"
t.string "cost"
t.integer "openspots"
t.boolean "approval"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "user_id"
t.integer "category_id"
end
add_index "posts", ["user_id"], name: "index_posts_on_user_id"
Here are my associations as well:
class Category < ActiveRecord::Base
has_many :posts
end
class Post < ActiveRecord::Base
belongs_to :user
belongs_to :category
has_many :comments
default_scope { order('created_at DESC') }
end
Finally I wanted to include my posts controller:
class PostsController < ApplicationController
def new
# #post = Post.new
#post = Post.new
#categories = Category.all.map{|c| [ c.name, c.id ] }
end
def create
#post = Post.new(params.require(:post).permit(:title, :description, :cost, :openspots, :approval, :category_id))
#post.category_id = params[:category_id]
#post.user = current_user
if #post.save
flash[:notice] = "Post was saved."
redirect_to #post
else
flash[:error] = "There was an error saving the post. Please try again."
render :new
end
end
def update
#post = Post.find(params[:id])
#post.category_id = params[:category_id]
if #post.update_attributes(params.require(:post).permit(:title, :description))
flash[:notice] = "Post was updated."
redirect_to #post
else
flash[:error] = "There was an error saving the post. Please try again."
render :edit
end
end
def edit
#post = Post.find(params[:id])
#post.category_id = params[:category_id]
end
def destroy
end
def index
#posts = Post.all
end
def show
#post = Post.find(params[:id])
end
end
Whenever I create a new post, the post is created successfully;however, the category id is never saved.
Here is my view as well:
<h1>New Post</h1>
<div class="row">
<div class="col-md-4">
<p>Guidelines for posts</p>

I'd like to check from and to times.
If from > to, I'd like display an error.
How can I edit my code?
Althogh I tried some codes with cover, include, I haven't be able to apply them to my code.
schema.rb
...
create_table "events", force: :cascade do |t|
t.time "from"
t.time "to"
...
schedules_controller.rb
...
def new
#schedule = Schedule.new
room = #schedule.rooms.build
schedule.events.build
end
def create
#schedule = current_user.schedules.build(schedule_params)
if #schedule.save
flash[:success] = "schedule created!"
redirect_to root_url
else
render 'new'
end
end
def edit
#day_max = Room.where("schedule_id = ?", #schedule.id).maximum(:day)
end
def update
#schedule.rooms.maximum(:day)
if #schedule.update(schedule_params)
flash[:success] = "schedule updated!"
redirect_to root_url
else
render 'edit'
end
end

<span class="form-inline">

It would be appreciated if you could give me how to check and display error.
You probably want to implement a validator in your event model, as explained in the documentation.
class Event < ActiveRecord::Base
validates :to, presence: true
validates :from, presence: true
validate do |e|
if e.from.present? && e.to.present? and e.from > e.to
e.errors[:base] << "To time must be after from time"
end
end
end
(What I would like to do)
Using form, I would like to save some data into GroupMessage model and at the same time,
to show the group message on the page where I filled in the form(groups/show?id=).
(What I did)
I wrote the code as below.
After pushing Create Group Message button,
I went to the page,
http:// localhost:3000/ groups/:id/group_messages
and got an error
"We're sorry, but something went wrong".
Help!!
(group/show?id=)
<%= form_for([#group, #group_message]) do |f| %>
<% if #group_message.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#group_message.errors.count, "error") %> prohibited this group_message from being saved:</h2>
<ul>
<% #group_message.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :member_id %><br />
<%= f.number_field :member_id %>
</div>
<div class="field">
<%= f.label :group_id %><br/>
<%= f.number_field :group_id %>
</div>
<div class="field">
<%= f.label :content %><br/>
<%= f.text_area :content %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

def show
#group = Group.find(params[:id])
#group_message = Group.find(params[:id]).group_messages.build
