Büroklammer :: Fehler (Es gab einen Fehler bei der Verarbeitung der Thumbnail-

Question

Paperclip :: Fehler in RegistrationsController # update ist ein Fehler war, die Thumbnail-Verarbeitung.

Ich laufe Rails 4.2.6

und paperclip", "~> 5.0.0"

Meine Anwendung Controller-Datei ist:

class NewsController < ApplicationController 
def create 
@news = News.new(news_params) 

    respond_to do |format| 
    if @news.save 
    format.html { redirect_to news_url, notice: 'News post was successfully created.' } 
    format.json { render :show, status: :created, location: @news } 
    else 
    format.html { render :new } 
    format.json { render json: @news.errors, status: :unprocessable_entity } 
    end 
    end 
end 

private 
def news_params 
    params.require(:news).permit(:topic, :header, :content, :link, :image) 
end 
end 

Meine Nachrichten Modell ist:

class News < ActiveRecord::Base 
    validates :image, presence: true 

    has_attached_file :image, styles: { thumb: "64x64#", small: "100x100#", med: "150x150#", large: "200x200# -adaptive-resize" }, default_url: "/images/:style/missing.png" 
    validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/ 
end 

Und meine Datenbank-Migration für Büroklammer ist:

class AddAttachmentImageToNews < ActiveRecord::Migration 
    def self.up 
    change_table :news do |t| 
     t.attachment :image 
    end 
    end 

    def self.down 
    remove_attachment :news, :image 
    end 
end 

Datenbank-Schema:

ActiveRecord::Schema.define(version: 20160809173534) do 

    create_table "news", force: :cascade do |t| 
    t.string "topic",    limit: 255 
    t.string "header",    limit: 255 
    t.string "content",   limit: 255 
    t.string "link",    limit: 255 
    t.datetime "created_at",      null: false 
    t.datetime "updated_at",      null: false 
    t.string "image_file_name", limit: 255 
    t.string "image_content_type", limit: 255 
    t.integer "image_file_size", limit: 4 
    t.datetime "image_updated_at" 
    end 
end 

Als ich rake db:migrate dies und dann versuchen, es zu benutzen ich die Paperclip::Error in NewsController#createThere was an error processing the thumbnail for dfc9ea4994791a9884f662cfa4333da420160809-29993-12b0k3n bekommen.

Completed 500 Internal Server Error in 815ms (ActiveRecord: 0.6ms) 

Paperclip::Error (There was an error processing the thumbnail for dfc9ea4994791a9884f662cfa4333da420160809-47024-t1m52a): 
    app/controllers/news_controller.rb:28:in `create' 

ich ein Attribut der Nachricht Klasse hatte zuvor Bild genannt, nicht sicher, ob das etwas vermasselt?

Es scheint, als wäre es ein Datenbankproblem, denn wenn ich einen Rake db: setup mache, funktioniert es gut. Aber ich möchte meine Datenbank nicht löschen, also ist das keine Option, da db:setup eine db:schema:load ausführt, löscht dies Daten auf dem Server.

Jede Hilfe oder Vorschläge wären willkommen. Vielen Dank.

Answer 1

Im news Modell geändert diese Zeile:

has_attached_file :image, styles: { thumb: "64x64#", small: "100x100#", med: "150x150#", large: "200x200# -adaptive-resize" }

Um dies:

has_attached_file :image, styles: { thumb: "64x64#", small: "100x100#", med: "150x150>", large: "200x200>" }

Ich vermute, die -adaptive-resize Verwirrungen Dinge, ich werde ein finden müssen verschiedene Möglichkeiten, das Bild zu skalieren, ohne es zu verzerren.
