I have a model pitch where i am fetching grounddetail_id. I want to show all the pitch available in the ground. How i can book pitch of ground..
grounddetails_controller.rb
class GrounddetailsController < ApplicationController
before_action :find_ground, only: [:show, :edit, :destroy, :update]
def index
#grounddetails = Grounddetail.all.order('created_at DESC')
end
def new
#grounddetail = Grounddetail.new
end
def edit
end
def show
end
def create
#grounddetail = Grounddetail.new(ground_params)
if #grounddetail.save
redirect_to #grounddetail
else
render 'new'
end
end
def update
if #grounddetail.update(ground_params)
redirect_to #grounddetail
else
render 'edit'
end
end
def destroy
#grounddetail.destroy
redirect_to root_path
end
private
def find_ground
#grounddetail = Grounddetail.find(params[:id])
end
def ground_params
params.require(:grounddetail).permit(:name, :working_hours, :end_time, :address, :contact_no, :email, :number_of_grounds, :description, :featured_ground)
end
end
routes.rb
Rails.application.routes.draw do
devise_for :users
devise_for :admins
resources :grounddetails do
resources :pitches
end
root "grounddetails#index"
end
model
grounddetail.rb
class Grounddetail < ActiveRecord::Base
has_many :pitches, dependent: :destroy
end
pitch.rb
class Pitch < ActiveRecord::Base
belongs_to :grounddetail
end
for now i just have pitch model and routes but in controller i am confused what to use. i can i book pitch of the ground. But for single ground i am able to book.
In the grounddetails#show action
def show
#pitches = #grounddetail.pitches
end
Then in the groundetails/show.html.erb, you can just use <%= #pitches %> to display the pitches of that grounddetail.
Update:
#in the show.html.erb
<% #pitches.each do |p| %>
<%= form_tag book_pitch_path(p) do %>
#your attributes here
<%= submit_tag "Book this Pitch" %>
<% end %>
<% end %>
#routes.rb
post :book_pitch/:id, to: 'pitches/book_pitch', as: 'book_pitch'
#in pitches_controller.rb
def book_pitch
#your actions here
end

I would like to route to the parent (journal) show page after deleting the child (habit) using the child_id.
In my app, a User can create journals, which then have multiple habits. I would like to be able to delete (and edit) a habit and then return to the journal show page, which displays all of the habits.
Getting the following and similar errors:
ActiveRecord::RecordNotFound in HabitsController#destroy
journal.rb
class Journal < ApplicationRecord
has_many :entries
has_many :habits
belongs_to :user
end
habit.rb
class Habit < ApplicationRecord

<% #journal.habits.each do |habit| %>

<div class="habit-status">
<%= simple_form_for [#journal, #habit] do |f| %>
<%= f.input :status, label: false, :inline_label => true %>
<% end %>
</div>
<div>
<%= link_to habit_path(habit), method: :delete do %>

redirect_to journal_path(#journal)

def set_journal
#journal = Journal.find(params[:journal_id])
end

end
Your trying to create URL to a deleted resource (#habit).
Change
def destroy
#habit.destroy
redirect_to journal_path(#habit, #journal)
end
to
def destroy
#habit.destroy
redirect_to journal_path(#journal)

I am new to rails and building my first app. I can't figure how to assign a car_id to new instances of awards that get created with the views/awards/new.html.erb file. Can anyone take a look and see where I am going wrong?
awards controller:
class AwardsController < ApplicationController
before_action :set_award, only: [:show]
def new
#award = Award.new
end
def index
#awards = Award.all
end
def create
#car = Car.params
#award = Award.new(award_params)
#award.save
redirect_to user_path(current_user)
end
def show
end
def destroy
end
private
def set_award
#award = Award.find(params[:id])
end
def award_params
params.require(:award).permit(:title, :year, :description)
end
end
cars controller
class CarsController < ApplicationController
before_action :set_car, only: [:show, :edit, :update, :destroy]
def new
#car = Car.new
end
def index
#cars = Car.all
end
def create
#car = Car.new(car_params)
#car.save
current_user.cars << #car
redirect_to current_user, :flash => { :success => "car created!" }
end
def edit
end
def update
#car.update(car_params)
if #car.valid?
#car.save
redirect_to user_path(current_user)
else
render :edit
end
end
def show
#car = Car.find(params[:id])
end
def destroy
#car.destroy
redirect_to user_path(current_user)
end

def set_car
#car = Car.find(params[:id])

class Car < ApplicationRecord
belongs_to :user

end

class Award < ApplicationRecord

has_one :user, through: :cars
end

Rails.application.routes.draw do
resources :awards
resources :cars
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

<%= f.label :description %>
<%= f.text_area :description %><br>

<%end%>
I need to be able to assign awards to specific cars, does anyone know how I can go about doing this?
Since you are using nested routes:
resources :cars do
resources :awards
end
Then:
app/controllers/awards_controller.rb
class AwardsController < ApplicationController
# add more into the array as you need
before_action :set_car, only: [:new, :create]
def new
#award = #car.awards.new
end
def create
#award = #car.awards.new(award_params)
#award.save
redirect_to user_path(current_user)
end
private
def set_car
#car = Car.find(params[:car_id])
end
end
app/views/awards/new.html.erb
<%= form_for [#car, #award] do |f| %>
...
Trivia:
because you are using nested routes, then your links would be something like:
<%= link_to 'New Award', new_car_award_path(SOMECAR) %>
<%= link_to 'Awards', car_awards_path(SOMECAR) %>
<%= link_to 'Edit Award', edit_car_award_path(SOMECAR, SOMEAWARD) %>
<%= link_to 'Delete Award', car_award_path(SOMECAR, SOMEAWARD), method: :delete %>
...just replace SOMECAR and SOMEAWARD with a Car and Award instances respectively, that you want to be in that link.
Recommendations:
handle validations errors. See tutorial
If possible, use shallow nesting
I am new to Ruby on Rails.I am facing a problem using nested resources.
I am building a learning app where there are courses and lessons.
Every course will have many lessons and a lesson belongs to only one course.
I am unable to create a lesson for a course currently.
Example : http://localhost:3000/courses/19/lessons/new is a page where i want to create and display lessons for course 19.

One problem i see is that you have defined route resources :lessons twice. Once, inside courses scope and second time outside.
The error seems to occur because in your view #course is nil. So, please check you set #course in a before_action inside lessons_controller#new action.
EDIT
class LessonsController < ApplicationController
before_action :set_course, only: [:new, :create]
def new
#lesson = #course.lessons.build
end
private
def set_course
#course = Course.find_by(id: params[:course_id])
end
end
Also replace has_many :lesson with has_many :lessons inside Course model.
First change you need to make in your Course model as you have singular lesson when defining many association:
has_many :lessons
Also let me know if their are any chances of lessons page being called without courses? If no then please remove:
resources :lessons
I guess also the two defining of courses in routes in creating issue. Please try removing the:
resources :courses
Let me know if you still face any issue.
I am using Devise as my authentication system and simple form. I get a NoMethodError in Groups#show and an undefined method 'name' for nil:NilClass error. I use model associations to tie the groups and posts together. When I do puts post.user.name it correctly displays in my terminal but that line causes the above error and it's referencing Groups#show for some reason. Any thoughts?
Routes
resources :groups do
resources :posts
end
Group Model
class Group < ActiveRecord::Base
validates :user_id, presence: true
belongs_to :user
has_many :posts
has_many :comments
has_many :attachments
end
Post Model
class Post < ActiveRecord::Base
validates :user_id, presence: true
validates :caption, presence: true
belongs_to :user
belongs_to :group
has_many :comments, dependent: :destroy
end
Group Controller
class GroupsController < ApplicationController

def new
#group = current_user.groups.build
end
def create
#group = current_user.groups.build(group_params)

if #group.save
redirect_to groups_path
else
render :new
end
end

<%#<%= render 'posts/post', post: post %>
<% end %>
SOLUTION: After asking on Reddit Rails, a generous user offered a solution that works. Apparently the <%= simple_form_for([#group, #group.posts.build]) do |f| %> creates a new post and adds it to the groups.posts array and so this causes issues when it iterates over _posts.html.erb and there is no user. More information can be found here: https://www.reddit.com/r/rails/comments/4lygix/unidentified_method_for_nil_class_devise_and/
But replace the above simple_form line of code with <%= simple_form_for([#group, Post.new(group: #group)]) do |f| %> seemed to do the trick, as suggested by the generous user in the reddit link above.
I am trying to set up a 5 star rating system so users can rate other users. At the moment everything is working, (create, delete, update etc...) but only the logged in user can rate himself. I cannot rate other users. I get no errors, it just redirects to the user profile page as it should but without added a rating to that user.
user.rb
class User < ActiveRecord::Base
has_many :reviews
review.rb
class Review < ActiveRecord::Base
belongs_to :user
end
reviews_controller.rb
class ReviewsController < ApplicationController
before_action :find_user
before_action :find_review, only: [:edit, :update, :destroy]
def new
#review = Review.new
end
def create
#review = Review.new(review_params)
#review.user_id = current_user.id
if #review.save
redirect_to user_path(#user)
else
render 'new'
end
end
def edit
end
def update
if #review.update(review_params)
redirect_to user_path(#user)
else
render 'edit'
end
end
def destroy
#review.destroy
redirect_to user_path(#user)
end
private
def review_params
params.require(:review).permit(:rating, :comment)
end
def find_user
#user = User.find(params[:user_id])
end
def find_review
#review = Review.find(params[:id])
end
end
_form which then gets rendered on show page:
<%= simple_form_for([#user, #user.reviews.build]) do |f| %>
<div id="rating-form">
<label>Rating</label>
</div>
<%= f.input :comment %>
<%= f.button :submit %>
<% end %>
<script>
$('#rating-form').raty({
path: '/assets/',
scoreName: 'review[rating]'
});
</script>
Any help getting this to work would be greatly appreciated!!
Do this:
#config/routes.rb
resources :users do
resources :reviews, only: [:new, :create]
end
#app/models/review.rb
class Review < ActiveRecord::Base
belongs_to :user
belongs_to :reviewed, class_name: "User", foreign_key: :reviewed_id
end
#app/controllers/reviews_controller.rb
class ReviewsController < ApplicationController
def new
#review = current_user.reviews.new
end
def create
#review = current_user.reviews.new review_params
#review.save
end
private
def review_params
params.require(:review).permit(:rating, :comment).merge(reviewed_id: params[:user_id])
end
end
#app/views/reviews/new.html.erb
<%= form_for #review do |f| %>
<%= f.number_field :rating %>
<%= f.text_field :comment %>
<%= f.submit %>
<% end %>
This would mean you'll have to include a reviewed_id column in your reviews table.
You'll be able to access it using: url.com/users/:user_id/reviews/new
The application will automatically fill the user_id and reviewed_id fields, so the rest of your code should work with the upgrade.
The big problem you have is that you're basically recording the user_id (presumably of who created the review)... but have no way of stipulating who the review is about.
The above code fixes that for you.
