Rails: How can I change Boolean values in a model? - ruby-on-rails

Question

I have a model called "Clients". The Clients model belongs to the Users model (Users model is associated with devise). The Client can do payments to me manually (cash only). When the client does this payment, I give them access to more pages in the website. To do this, I was thinking I add a migration to the Client model like:
rails generate migration add_paid_to_clients paid:boolean
Then when the clients pay the money, I can just go to their profile and click on an option (maybe a checkbox) saying the client has paid. Only the admin(me) can see this part. The way I would implement that is, in the user profile view:
<% if current_user.user_type == :client%>
userinformation....blablabla
<% elsif current_user.user_type == :admin %>
userinformation....blablabla
AND the checkbox I talked about.
<% end %>
The user_type is a predefined function to figure out if the current_user is admin or just a client. I have done this part.
So in the private pages(the pages you can get access to after paying), I can have some logic like If current_user.paid? THEN show them this page.
How can I implement the checkbox part? After the migration(if there is a better way,please let me know),how can I just "flip the switch" to let them get more access?
My Clients contoller:
class ClientController < ApplicationController
before_action :find_client, only: [:show, :edit, :update, :destroy]
def index
end
def show
end
def new
#client = current_user.build_client
end
def create
#client = current_user.build_client(client_params)
if #client.save
redirect_to clients_path
else
render 'new'
end
end
def edit
end
def update
end
def destroy
#client.destroy
redirect_to root_path
end
private
def client_params
params.require(:client).permit(:name, :company, :position, :number, :email, :client_img)
end
def find_client
#client = Client.find(params[:id])
end
end
This is not real cash, this is a project for school.

Answer 1

Something like this?
In the form for the admin:
<%= form_for #user do |f| %>
<%= check_box_tag 'paid', 'yes', true %>
<%= f.submit "Update" %>
<% end %>
Then in the controller:
class ClientController < ApplicationController
before_action :find_client, only: [:show, :edit, :update, :destroy]
def index
end
def show
end
def new
#client = current_user.build_client
end
def create
#client = current_user.build_client(client_params)
if #client.save
redirect_to clients_path
else
render 'new'
end
end
def edit
end
def update
end
def destroy
#client.destroy
redirect_to root_path
end
private
def client_params
if current_user.user_type == :admin
# This is different because only admin can update paid
# To make a string a boolean
params[:client][:paid] = params[:client][:paid] == 'yes'
params.require(:client).permit(:paid, :name, :company, :position, :number, :email, :client_img)
else
params.require(:client).permit(:name, :company, :position, :number, :email, :client_img)
end
end
def find_client
#client = Client.find(params[:id])
end
end
you can do this more properly using the protected attributes, described here
After that you want to make a PaidController
class PaidController < ApplicationController
before_filter :authorize_paid
def authorize_paid
return head(:forbidden) unless current_user.paid?
end
end
Then make sure that all the protected pages inherit from the PaidController
