如何根据图片模型在Ruby On Rails中的CKeditor中设置图像的大小？ [英] How to set the size of an image within CKeditor in Ruby On Rails according to the picture model?

问题描述

这可能是一个重复的问题，但我对此表示怀疑。

我有以下情况：

我在红宝石上使用了两种广泛使用的宝石：回形针和ckeditor（正在使用回形针）。

I have a ruby on rails apllication with two widely used gems: paperclip and ckeditor (which is working with paperclip).

我希望根据发布的类型调整在Ckeditor屏幕中上传的图像的大小。现在，虽然C确实上传了我在picture.rb模型中设置的不同类型的尺寸，但在Ckeditor或其他任何产品中都没有一个按钮可以帮助解决此问题。

I want the size of the image that I upload in the Ckeditor screen to be resized depending on the type of 'post'. Right now there's not a button that can help with that in the Ckeditor or anything, though it does upload the different type of sizes I set in the picture.rb model:

class Ckeditor::Picture < Ckeditor::Asset
  has_attached_file :data,
                :url  => "/ckeditor_assets/pictures/:id/:style_:basename.:extension",
                :path => ":rails_root/public/ckeditor_assets/pictures/:id/:style_:basename.:extension",
                :styles => { :content => '600>',:medium => '300x300', :quintet => '150x150', :thumb => '118x100#' }


  validates_attachment_size :data, :less_than => 2.megabytes
  validates_attachment_presence :data


  def url_content
    url(:content)
  end
end

问题是从Ckeditor保存的内容（图像和标签）将显示为

The problem is that the content (images and tags) that gets saved from the Ckeditor will be displayed like

.post_body= raw post.content

其中post.content =

where post.content =

 <p><img alt="" src="/ckeditor_assets/pictures/2/content_cartoon_paul-the-good-fight.gif" /></p>

CKeditor使用的图像是标准图像，而不是具有特定尺寸或类型的图像。
如何设置大小或类型？

The image that the CKeditor is using is the standard image and not the image with a certain size or type. How do I set that size or type?

推荐答案

在url_content方法中，将：content替换为您的样式要求（例如：: medium，：quintet，：thumb）。请注意，对于在设置特定样式之前上传的任何图像，将没有该尺寸的相应图像。上传的所有图片都会将不同的版本保存到ckeditor_assets路径（例如原始，中型，拇指），然后您可以更改url参数以指向正确的版本。因为我正在测试已经上传的图片，所以花了一段时间才意识到这一点，因此在测试它是否可行时，请确保指定了所需的所有样式，然后上传新图片。这样便可以更改url_content的参数。

In the url_content method, replace :content with the style you require (e.g., :medium, :quintet, :thumb). Note that for any images uploaded BEFORE you set a specific style, there will be no corresponding image of that size. Any image uploaded will get different versions saved to the ckeditor_assets path (e.g., original, medium, thumb) and then you can change the url parameter to point to the correct version. It took me a while to realize this since I was testing with an already uploaded picture, so when testing if it works, make sure all the styles you want are specified and then upload a new picture. Changing the parameter for url_content should work then.
