In this screen cast we demonstrate some basic concepts how to use LipsiADMIN as a scaffold for the backend of your rails app.

In particular we focus on:

• Start a new project and attach LipsiADMIN
• Add new models and scaffold them
• Add some relations for explain how we can easily make associations with LipsiADMIN
• Create a editable grid
• Create and Manage roles and permission

In this screencast we use Rails 2.3.5, ExtJS 3.1, Osx Snow Leopard, TextMate.

Mirec ask us:

I created some custom model attributes in model.rb file, but i found no way to include those in the list view.

Whatever i try it gives me translation error.

Is this implemented, or is there a workaround?

For this reason we want show you how you can easy extend the ExtJs GridPanel.

When our staff build the frontend of a site is always necessary redefine the thumbs of an Image.

99% of our customers change the size or the final layout is a little different

It's true our attachment table can define thumbs and we can reprocess them like showed in this article

But if don't want every time add a new line in our code and reprocess all of them?

If the image did't reside on our server?

image_tag("/path/to/my/image.png", :size => "180#")

image_tag("http://www.remote.com/image.png", :size => "180x180!")

Create on the fly (and once time) a new image in our public folder

With Lipsiadmin 5.0 the menu is cached, this because for example we want to build a category tree like:

Today I need to import from a CSV file about 14500 records. Doing it the old way isn't a great idea, the server will be overloaded and the result may be unesxpected!

Here Loops take the field, let's figure out how with an example.
