project_sites_controller.rb
class ProjectSitesController < ApplicationController
before_action :authenticate_user!
before_action :is_project_site?, except: [:show]
before_action :set_project_site, only: [:show, :edit, :update, :destroy]
# GET /project_sites
# GET /project_sites.json
def index
#project_sites = ProjectSite.all.order("created_at DESC")
end
# GET /project_sites/1
# GET /project_sites/1.json
def show
#manager_remark = ManagerRemark.new
#manager_remark.project_site_id = #project_site.id
end
# GET /project_sites/new
def new
#project_site = ProjectSite.new
end
# GET /project_sites/1/edit
def edit
end
# POST /project_sites
# POST /project_sites.json
def create
#project_site = ProjectSite.new(project_site_params)
respond_to do |format|
if #project_site.save
format.html { redirect_to #project_site, notice: 'Project site was successfully created.' }
format.json { render :show, status: :created, location: #project_site }
else
format.html { render :new }
format.json { render json: #project_site.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /project_sites/1
# PATCH/PUT /project_sites/1.json
def update
respond_to do |format|
if #project_site.update(project_site_params)
format.html { redirect_to #project_site, notice: 'Project site was successfully updated.' }
format.json { render :show, status: :ok, location: #project_site }
else
format.html { render :edit }
format.json { render json: #project_site.errors, status: :unprocessable_entity }
end
end
end
# DELETE /project_sites/1
# DELETE /project_sites/1.json
def destroy
#project_site.destroy
respond_to do |format|
format.html { redirect_to project_sites_url, notice: 'Project site was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_project_site
#project_site = ProjectSite.find(params[:id])
end
# Never trust parameters frmanager_level_twoom the scary internet, only allow the white list through.
def project_site_params
params.require(:project_site).permit(:name, :date, :file)
end
def is_project_site?
redirect_to root_path unless (current_user.role=='project_site')
end
end
This is how my manage remark controller looks.
Manager_Remarks_controller.rb
class ManagerRemarksController < ApplicationController
def create
#manager_remark = ManagerRemark.new(remark_params)
#manager_remark.project_site_id = params[:project_site_id]
#manager_remark.save
redirect_to project_site_path(#manager_remark.project_site)
end
def remark_params
params.require(:manager_remark).permit(:name, :remark, :decision)
end
end
