Undefined method error in rails? - ruby-on-rails

Question

I have a model where students can enter information about themselves and others can view them. Since there are a lot of profiles, I have added a search section too. If they want only CS majors, they can select from a drop down. I had things like major, college... today I added "level", which is level of education and I get an error (Error shown at the end). I know this is long, but any help would be really really useful. Thanks!
(Userinfo is the student model)
My controller looks like this:
class UserinfosController < ApplicationController
before_action :find_userinfo, only: [:show, :edit, :update, :destroy, :log_impression]
def index
#userinfors = Userinfo.search(params[:search])
#search = Search.new
#college = Userinfo.uniq.pluck(:college)
#major = Userinfo.uniq.pluck(:major)
#level = Userinfo.uniq.pluck(:level)
end
def show
end
def new
#userinformation = current_user.build_userinfo
end
def create
#userinformation = current_user.build_userinfo(userinfo_params)
if #userinformation.save
redirect_to userinfo_path(#userinformation)
else
render 'new'
end
end
def edit
end
def update
if #userinformation.update(userinfo_params)
redirect_to userinfo_path(#userinformation)
else
render 'edit'
end
end
def destroy
#userinformation.destroy
redirect_to root_path
end
private
def userinfo_params
params.require(:userinfo).permit(:name, :email, :college, :gpa, :major, :token, :skills, :level)
end
def find_userinfo
#userinformation = Userinfo.friendly.find(params[:id])
end
end
My information fill out form (please note how the way of input is different in major and level of edu, maybe thats the problem?):
<%= simple_form_for #userinformation, :html => { :multipart => true } do |f| %>
<%= f.input :name, required: true, label: 'Full name' %>
<%= f.input :college, required: true, label: 'Name of college' %>
<%= f.input :gpa, required: true, label: 'Enter GPA' %>
<%= f.input :email, required: true, label: 'Enter email address' %>
<%= f.input :major, required: true, label: 'Major' %>
<%= f.input :level, collection: ["College undergrad", "College grad"], required: true, label: 'Level of education' %>
<%= f.input :skills, required: true, label: 'Skills' %>
<%= f.button :submit, 'Create account' %>
<% end %>
Search controller:
class SearchesController < ApplicationController
def new
#search = Search.new
#college = Userinfo.uniq.pluck(:college)
#major = Userinfo.uniq.pluck(:major)
#level = Userinfo.uniq.pluck(:level)
end
def create
#search = Search.create(search_params)
redirect_to #search
end
def show
#search = Search.find(params[:id])
end
private
def search_params
params.require(:search).permit(:keyword, :college, :min_gpa, :major, :token, :level )
end
end
Search model:
class Search < ActiveRecord::Base
def search_userinfos
userinfos = Userinfo.all
userinfos = userinfos.where(["name LIKE ?","%#{keyword}%"]) if keyword.present?
userinfos = userinfos.where(["college LIKE ?", college]) if college.present?
userinfos = userinfos.where(["cast(gpa as numeric) >= ?", min_gpa]) if min_gpa.present?
userinfos = userinfos.where(["major LIKE ?", major]) if major.present?
userinfos = userinfos.where(["level LIKE ?", level]) if level.present?
userinfos = userinfos.order("gpa")
return userinfos
end
end
This is where the search section is displayed (index view):
<%= simple_form_for #search do |s| %>
<%= s.input :keyword, label: 'Name' %>
<label>College</label>
<%= s.select :college, options_for_select(#college), :include_blank => true %>
<%= s.input :min_gpa, label: "Minimum GPA" %>
<label>Major</label>
<%= s.select :major, options_for_select(#major), :include_blank => true %>
<label>Job type</label>
<%= s.select :level, options_for_select(#level), :include_blank => true %>
<%= s.button :submit, "Search" %>
<% end %>
The error I get when I try to visit the index view:
NoMethodError in Userinfos#index
Showing app-path/index.html.erb where line #25 raised:
undefined method `level' for #<Search:0x000000139d6c38>
Line 25 is:
<%= s.select :level, options_for_select(#level), :include_blank => true %>
Everything works if I remove that line. When I show the education level in the user profile page, it works perfectly.
Schema for searches:
create_table "searches", force: :cascade do |t|
t.string "keyword"
t.string "college"
t.decimal "min_gpa"
t.string "major"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end

Answer 1

As you commented, you do not have a level attribute in your Search model.
rails g migration add_level_to_searches level:string
And of course
rails db:migrate
Happy to help!
