I have report_controller where I have two objects, #report and #reporte, and I want to save both objects in database. When validation fails, I want to get fields populated in rendered form.
I can't use just #report = ReportMain.new(params[:report_main]) because I have two objects and just one params object.
I use exportnew action to show form, and encreate to save this form.
There is some simple way to get form populated?
ReportController:
class ReportController < ApplicationController
before_filter :authenticate_user!
before_filter :load
layout "application"
def load
#company = Company.find_by_id(current_user.company_id)
#date = Date.today
#report = ReportMain.new
#reporte = ReportE.new
end
def index
list
render("list")
end
def list
#reports = ReportMain.all
end
def exportnew
render("ennew")
end
def encreate
#report = ReportMain.new
#reporte = ReportE.new
#reportparam = params[:report_main]
#report.waste_id = params[:waste][:code]
#report.warehouse_id = Warehouse.find_by_user_id(current_user.id).id
#report.user_id = current_user.id
#report.company_id = current_user.company_id
#report.amount = #reportparam[:amount]
#report.isimport = false
#report.isfinished = false
#report.reportnumber = ReportMain.where(:company_id => current_user.company_id).count.to_i+1
if #report.save
#reporte.report_main_id = #report.id
else
#report_main = #report
render("etnew")
return
end
#reporte.vrstaotpada = params[:vrstaotpada]
#reporte.nacinpakovanja = params[:nacinpakovanja]
#reporte.ispitivanjebroj = #reportparam[:ispitivanjebroj]
#reporte.datumispitivanja = #reportparam[:datumispitivanja]
#reporte.q_pripadnost = #reportparam[:q_pripadnost]
#reporte.datumpredaje = #date
if #reporte.save
redirect_to(:action => 'show', :id => #reporte.id)
flash[:notice] = "Izveštaj je uspešno kreiran."
else
#report_main = #report
render("etnew")
end
end
def show
#report = ReportMain.find(params[:id])
#warehouse = #report.warehouse.name
end
end
View starts with (it's huge HTML):
<%= form_for(:report_main, :url => {:action => 'encreate'}) do |f| %>
Since you want your form to get populated after validation fails, I suggest make your from to submit through AJAX. There is a jQuery plugin which can help http://jquery.malsup.com/form/

From travels, which belongs to offer, I'm trying to render a form generated with the mail_form gem.
But I get an error with this message:
*undefined method `model_name' for NilClass:Class*
travels/show
= render :partial => '/question_forms/form', :question_form => #question_form
Any hint how to get this? I've tried including the question_form model as an association to travel, but it doesn't work.
This is the question_forms_controller default code:
class QuestionFormsController < ApplicationController
def new
#question_form = QuestionForm.new
end
def create
begin
#question_form = QuestionForm.new(params[:question_form])
#question_form.request = request
if #question_form.deliver
flash.now[:notice] = 'Thank you for your message!'
else
render :new
end
rescue ScriptError
flash[:error] = 'Sorry, this message appears to be spam and was not delivered.'
end
end
end
In my travels_controller I tried to load #question_form using the same method, but this doesn't seem the way:
def new
#offer_season = OfferSeason.find(params[:offer_season_id])
#travel = #offer_season.travels.find(params[:id])
#question_form = #travel.questionforms.new
end
def create
#offer_season = OfferSeason.find(params[:offer_season_id])
#travel = #offer_season.travels.find(params[:id])
begin
#question_form = #travel.questionforms.new(params[:question_form])
#question_form.request = request
if #question_form.deliver
flash.now[:notice] = 'Thank you for your message!'
else
render :new
end
rescue ScriptError
flash[:error] = 'Sorry, this message appears to be spam and was not delivered.'
end
end
in my Rails app in DB i have some query.
# PostController
#post.query # => 'blabla'
and i want put this string in google or yahoo
in simple ruby file i use
require ... all gems
Capybara.app_host = 'http://www.google.com/'
and
class Google
include Capybara::DSL
def search
visit('/')
fill_in "q", :with => "blah blah"
click_button("Google")
...
but how can I put this code in controller (or model method)?
Capybara is not intended for such use. You might want to try mechanize instead.
class PostsController < ApplicationController
require 'capybara'
require 'capybara/dsl'
include Capybara::DSL
Capybara.current_driver = :webkit
def index
#posts = Post.all
end
def show
#post = Post.find(params[:id])
visit(#post.search_type)
fill_in "q", :with => #post.query
click_button("Google")
loop_variable = 0
num_of_page = 1
max_count_of_page = 4
flag_on_break = false
while(loop_variable == 0) do
has_on_page = page.has_content?(#post.search_question)
if has_on_page
loop_variable = 1
else
find('.b:last a').click
num_of_page += 1
end
if num_of_page > max_count_of_page
flag_on_break = true
break
end
end
if flag_on_break
#number = 'Nothing not found'
else
#number = num_of_page
end
end
def new
#post = Post.new
end
def create
#post = Post.new(params[:post])
if #post.save
flash[:notice] = "Post created!"
redirect_to root_path
end
end
end
this is a piece of my code - but the main idea, I think, is understandable
I want to get all the microposts where 'something' = true.
This code works fine
class UsersController < ApplicationController
.
.
.
def show
#user = User.find(params[:id])
#microposts = #user.microposts
#titre = #user.nom
end
end
But when I tried to make a where sql method this code doesn't work.
class UsersController < ApplicationController
.
.
.
def show
#user = User.find(params[:id])
#microposts = #user.microposts.where("something = 'true'")
#titre = #user.nom
end
end
any idea ?
def show
#user = User.find(params[:id])
#microposts = #user.microposts.where(something: true)
#titre = #user.nom
end
See here or here for more info on narrowing the query scope.
Write like this:
Micropost.where(user_id: params[:id], something: true)
Is this action ok? Can it be improved in any way? Should I extract the setting up of the order to a private method and just call that? Or is it fine and in line with the 'Rails way'?
def create
#order = Order.new(params[:order])
#product = Product.find(session[:product])
#order.amount = session[:total_amount]
#order.ip_address = request.remote_ip
#order.product_id = #product.id
#order.product_price = #product.price
#order.voucher = #voucher_value
#order.friend_id = session[:friend_id]
if #order.save
if #order.purchase
render :action => "success"
reset_friend_session_codes
else
render :action => "failure"
end
else
render :action => 'new'
end
end
TIA.
I would factor out as much as I could into a private method in the order model and call it with one of the model hooks, such as before_validation. That's too much logic for an action, and tramples all over MVC.
I have a basic rails question where I need to save two associated objects.
The association is Rtake has_many :companies and Company belongs_to :rtake
def create
#rtake = RTake.new(:email => params[:contact_email])
#rtake.role = "PROVIDER"
#company = #rtake.companies.build(params[:company])
#company.rtake = #rtake
respond_to do |format|
if #company.save_company_and_rtake
format.html{ redirect_to admin_companies_url}
else
flash.now[:errors] = #company.errors.full_messages.join(", ")
format.html{ render "new" }
end
end
end
In my company.rb class I have
def save_company_and_rtake
status1 = self.save(:validate => false)
status2 = self.rtake.save(:validate => false)
status = status1 && status2
status
end
The problem I face is that the company.rtake_id remains nil. Ideally shouldn't the company.rtake_id get updated to the #rtake.id after save.
I know I am missing something basic. Would appreciate some help.
You shouldn't need this line:
#company.rtake = #invitation
#invitation is nil from what you've shown .
But also, when you built the #company, #rtake.id isn't set because it hasn't been saved.
#company = #rtake.companies.build(params[:company])
#company.rtake = #rtake
#rtake.companies.build(params[:company]) This already means #company.rtake == #rtake. it's redundent here.
