This is a Ruby on Rails App where users can submit recipies along with descriptions, directions and image of the recipe. ###Gems Used
- Paperclip - To upload image to the Recipes table
- Cocoon - Used to render a nested form
- Haml - To write views in Haml
##Steps
- Generate a recipes controller (having title and description)
rails g controller recipes - Generate a Recipe model
rails g model Recipe title:string description:text user_id:integer
Then run the rake db:migrate command
- Setting up recipe views
recipes_controller.rb
before_action :find_recipe, only: [:edit,:update,:destroy,:show]
def index
@recipes = Recipe.all
end
def new
@recipe = Recipe.new
end
def create
@recipe = Recipe.new(recipe_params)
if @recipe.save
#success
else
render 'new'
end
end
private
def find_recipe
@recipe = Recipe.find(params[:id])
end- Setting up new forms using simple_forms and haml
new.html.haml
- simple_form_for @recipe, html: {multipart: true} do |f|
= f.input :title,input_html: {class: 'form-control'}
= f.input :description,input_html: {class: 'form-control'}
= f.input :image,input_html: {class: 'form-control'}
= f.button :submit,input_html: {class: "btn btn-default"}Thus using simple_form_for helper a field and label can be rendered using a single line of code.
_error_messages.html.haml
- if @recipe.errors.any?
#errors
%p
=@recipe.errors.count
prevented this form from saving
%ul
- if @recipe.errors.full_messages.each do |msg|
%li= msg
