Я сталкиваюсь с этой ошибкой, когда я загружаю изображение в зону сброса (это как средство просмотра в форме), и я не вижу, что происходит.
У меня все взгляды мыслились ...
ActionView::MissingTemplate (Missing template finished_guitars/show, application/show with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :jbuilder]}. Searched in:
* "/Users/Billy/code/guitar_app/app/views"
):
У меня есть две модели:
finish_guitar , имеющее отношение к attachment ,
Я использую скрепку для загрузки изображений в приложение
Я считаю, что с моими моделями все в порядке:
attachment.rb
class Attachment < ApplicationRecord
belongs_to :finished_guitar
has_attached_file :image, styles: { medium: "300x300>", thumb: "120x120>" }, default_url: "/images/:style/missing.png"
validates_attachment_content_type :image, :content_type => ["imagse/jpg", "images/jpeg", "images/png"]
end
finished_guitar.rb
class FinishedGuitar < ApplicationRecord
accepts_nested_attributes_for :attachments, allow_destroy: true
has_many :attachments
end
Я должен быть не прав где-то в контроллерах:
attachments_controller.rb
class AttachmentsController < ApplicationController
def create
@attachment = Attachment.new(attachment_params)
respond_to do |format|
if @attachment.save
format.html { redirect_to @finished_guitar, notice: 'Attachment was successfully created.' }
format.json { render :show, status: :created, location: @attachment }
else
format.html { render :new }
format.json { render json: @attachment.errors, status: :unprocessable_entity }
end
end
end
private
def attachment_params
params.require(:attachment).permit(:id, :finished_guitar_id, :image)
end
end
finished_guitars_controller.rb
class FinishedGuitarsController < ApplicationController
def index
@finished_guitars = FinishedGuitar.all
end
def show
@finished_guitar = FinishedGuitar.find(params[:id])
@attachments = @finished_guitar.attachments.all
end
def new
@finished_guitar = FinishedGuitar.new
@attachments = @finished_guitar.attachments.build
end
def create
@finished_guitar = FinishedGuitar.new(finished_guitar_params)
respond_to do |format|
if @finished_guitar.save
unless params[:attachments].nil?
params[:attachments]['image'].each do |a|
@finished_guitar = @finished_guitar.attachments.create!(:image => a)
end
end
format.html { redirect_to @finished_guitar, notice: 'Guitartest was successfully created.' }
format.json { render :show, status: :created, location: @finished_guitar }
else
format.html { render :new }
format.json { render json: @finished_guitar.errors, status: :unprocessable_entity }
end
end
end
def destroy
@finished_guitar = FinishedGuitar.find(params[:id])
@finished_guitar.destroy
end
private
def finished_guitar_params
params.require(:finished_guitar).permit(:title, :description, attachments_attributes: [:finished_guitar_id, :id, :image])
end
end
Edit:
приложение / просмотров / finished_guitars / _form.html.erb
<div class="content">
