Rails 3.1 serving images from vendor/assets/images - ruby-on-rails-3

I am trying to put some external images (used by a jQuery plugin) to vendor/assets/images in my Rails 3.1 app. Problem is that when I try something like:
<%= image_tag "ui-bg_flat_75_ffffff_40x100.png" %>
I get an error:
No route matches [GET] "/assets/ui-bg_flat_75_ffffff_40x100.png"
I checked my Rails.application.config.assets.paths and it list these dirs:
..../app/assets/images
..../app/assets/javascripts
..../app/assets/stylesheets
..../vendor/assets/images
..../vendor/assets/stylesheets
..../.rvm/gems/ruby-1.9.2-p180#mygems/gems/jquery-rails-1.0.9/vendor/assets/javascripts
As you can see /vendor/assets/images is listed there. If I put my image to app/assets/images everything works.
I thought that new asset pipeline was supposed to go through all assets dirs and serve requested file wherever it finds it.
Does anyone knows what's the problem here?

I had to restart my rails server after creating the vendor/assets/images directory. Before this, I was seeing the same error as you ("No route matches [GET]").
My guess is that the rails server does not check these directories if they did not exist when it was first started. When you open a rails console to diagnose the issue, you get a new instance of rails which knows about the directory, which only adds to the confusion.

If you are using a jQuery UI Theme Roller theme then the problem might be that in the jquery-ui css file the images are referenced within a sub folder 'images'.
I.e. you either have to put your images in a folder './app/assets/images/images' or you have to edit the jquery-ui css file and remove the 'images/' folder prefix.

The asset pipeline is described in this rails guide by Ryan Bigg (draft status at the moment).
http://ryanbigg.com/guides/asset_pipeline.html and http://ryanbigg.com/2011/06/sprocket-asset-tags-internals/ for the references.
According to this, your example should work.
Extract:
Assets can be placed inside an application in one of three locations: app/assets, lib/assets or vendor/assets.
app/assets is for assets that are owned by the application, such as custom images, javascript files or stylesheets.
lib/assets is for your own libraries’ code that doesn’t really fit into the scope of the application or those libraries which are shared across applications.
vendor/assets is for assets that are owned by outside entities, such as code for JavaScript plugins.
Any subdirectory that exists within these three locations will be added to the search path for Sprockets (visible by calling Rails.application.config.assets.paths in a console). When an asset is requested, these paths will be looked through to see if they contain an asset matching the name specified. Once an asset has been found, it’s processed by Sprockets and then served up.
I have tested with an example in my app and the same syntax as yours works. Maybe you have a typo in the name of your asset.
For Martin: search path for Sprockets is visible by calling Rails.application.config.assets.paths in a console.

Maybe you should create another folder in /assets/images. You make a name 'images' and then you just copy all jquery-ui image and paste on folder 'images' that you create before. Hopefully this will help you.

Images uploaded in Vue.js production mode not showing

I am a bit new to Vue.js. I am doing a social media application that allows users to upload and share images with others. I store my images in src/assets folder during development. However, when I build the project, all images are put in the dist folder. Therefore, what can I do to enable users to still upload images on production? Do I create the assets directory in the dist folder?
I have since tried different ways, including storing images on the backend. In dooing this, I reference the backend path relatively, using, for example, ../../../backend/public/assets..., and it works on development. However, when I build, the images that existed in the backend directory at the time of building are visible, however, whenever I try uploading more on production to the ../../../backend/public/assets... directory, they are uploaded successfully but are not visible (that is on production). I get an error that Cannot find module './image_name.image_extension'.
What am I doing wrong?
I have seen similar questions like this but there was no answer.
You must set your public path and change your way!!
first step to do is creating vue.config.js in your root directory, if you want to know more details, read this: https://cli.vuejs.org/config/
for example, I define prefix path for my files:
module.exports = {
publicPath:
process.env.NODE_ENV === "production" ? "/" : "/",
};
remember, It's better if you use "#" to define your paths.
for example, if you want to load a image which located in src/assets/files/img/myImage.png, you can use #/assets/files/img/myImage.png in template section for binding or script section of your .vue files!
It always help you to find correct path of your files.
and finally your way is not standard because "src/assets/..." will used for compiled scripts and styles and also your files which you want to use on your UI layout like static images. so you have to use "public/assets/..." directory to save your file, then you will see everything is going well for you.
if you have a more question or stuck solving this problem again, I'm here to fix your issues.

Dropwizard serve external images directory

I have a dropwizard API app and I want one endpoint where I can run the call and also upload and image, these images have to be saved in a directory and then served through the same application context.
Is it possible with dropwizard? I can only find static assets bundles.
There is similar question already: Can DropWizard serve assets from outside the jar file?
The above module is mentioned in the third party modules list of dropwizard. There is also official modules list. These two lists are hard to find maybe because the main documentation doesn't reference them.
There is also dropwizard-file-assets which seems new. I don't know which module will work best for your case. Both are based on dropwizard's AssetServlet
If you don't like them you could use it as example how to implement your own. I suspect that the resource caching part may not be appropriate for your use case if someone replace the same resource name with new content: https://github.com/dirkraft/dropwizard-file-assets/blob/master/src/main/java/com/github/dirkraft/dropwizard/fileassets/FileAssetServlet.java#L129-L141
Edit: This is simple project that I've made using dropwizard-configurable-assets-bundle. Follow the instructions in the README.md. I think it is doing exactly what you want: put some files in a directory somewhere on the file system (outside the project source code) and serve them if they exist.

How to include css pie in Rails 3.2 with asset pipeline?

I would like to include PIE.htc in my Rails application to make CSS3 easier for IE. I can't seem to figure out how to include the PIE.htc file.
I tried to include PIE.htc in my assets folder as well as assets/stylesheets folder, but I no routes matching error.
How do I include PIE.htc with rails asset pipeline?
Try the solution in this post: Using PIE.htc in rails
Basically, it should be:
behavior: url(/assets/PIE.htc);
Also, if you want to be completely sure that the PIE.htc file is being loaded, open it and add an alert as so:
<script type="text/javascript">
alert("PIE works);
If the file if being loaded, a popup should appear showing the message.

Is there a "Rails Way" include a jQuery plugin in the Asset Pipeline?

Many jQuery plugins have the following directory structures:
/<plugin name>
../css
../images
../js
The CSS files usually have relative links to the images in them. What I want to do is include these plugins in the Rails Way under the Asset Pipeline, and hopefully that doesn't involve having to renamed the file references to remove the relative links. Is there such a Rails Way?
Could it also be that it's overkill to include an already-minified jQuery plugin in the Asset Pipeline?
You should try to add your assets to the load path which is the recommended way, as far as I know. If the application you're running has the assets-pipeline activated, it should find your assets after expanding the path in your application.rb
config.assets.paths << Rails.root.join("plugins/plugin_name/assets/")
Not shure, if this is what you asked for but if not, you should check: http://guides.rubyonrails.org/asset_pipeline.html#asset-organization
Remeber to restart your server
I had the same issue and also tried to find "the Rails way" to do this. And this is what I ended up with at the end of the day:
As Rob already mentioned:
vendor/assets is for assets that are owned by outside entities, such as code for JavaScript plugins and CSS frameworks.
Source: 2.1 Asset Organization
Lets take a practical example: using the jquery_datepicker gem (Note: we had to use a workaround because of this issue: bundle pack does not work with git sources).
1) Installing the gem (pretty straighforward):
cd vendor/gems
git clone https://github.com/albertopq/jquery_datepicker.git
2) Add this to your Gemfile
gem 'jquery_datepicker', :path => 'vendor/gems/jquery_datepicker'
3) Install a jquery-ui theme
From ThemeRoller select a theme, check Datepicker and Slider
and the jQUery version
Download and extract the content of the package
CSS/images from the css/theme-name folder move them:
jquery-ui-1.8.xx.custom.css to app/vendor/stylesheets/
the images folder to app/vendor/images/ (yes, move the entire folder images so you end up with something like this app/vendor/images/images/ui-icons_256x240.png
i18n from the development-bundle/ui/i18n folder (optional) move them to:
Create a folder i18n under app/vendor/javascripts/
move jquery.ui.datepicker-xx.js to this folder app/vendor/javascripts/i18n/
make sure the i18n folder is loaded so include in application.js
//= require_directory ./i18n
vendor/assets is loaded automatically AFAIK so you don't have to include the path in the asset pipeline.
I'd like to see how others are approaching this, it's a very good question.
I think the reason you haven't received an answer is because it's kind of unclear what you're asking. Are you asking if it's overkill to put your plugins in the asset pipeline? Are you asking if you have to rename file references?
I always put all my jquery plugins in my asset pipeline. Overkill or not, there all in one place and they only get compiled once so even if compiling them takes longer, it doesn't affect my app.

Changing Inside Assets Folder In Yii Framework

I came to notice that there is one folder called assets in the root folder.To know more about it,I went through this link.Now I want to know adding some css in these files is good or shall I add css to to the main.css file inside css folder.
The asset folder is automatically generated by Yii based upon your environment so best avoid putting your CSS, images etc inside here. It also best to not commit these folders and files into SVN as they are automatically generated and folder names will differ from your qa/staging/live site to your local site.
There are some good reasons to use Yii's assets.
it prevents naming conflicts in css and js files
it allows you to keep CSS and JS files under your document-root but outside of your web-root (for easier version control)
it allows to easily switch between sets of CSS & JS files, rather than having to deal with each file individually (suppose the system admin needs to revert back to a previous version).
it allows you to publish assets (images, JS & CS) to several websites hosted on the same server.
Please check here or there for more details.
Well, when i started my first Yii project, i also put my CSS and JS files in assets. It works but then i found that its not just the right way. Its better to make a separate directory for your CSS file(s). Also there are some auto generated files in assets, so to avoid mix-up with those and your i prefer to make it separate. Hope you got the point.
