Web App Theme

Web App Theme is a rails generator by Andrea Franz that you can use to generate admin panels quickly. Inspired by cool themes like Lighthouse, Basecamp, RadiantCMS and others, it wants to be an idea to start developing a complete web application layout.


Install the gem with:

sudo gem install web-app-theme -s

You can also install it as a rails plugin:

script/plugin install git://


Theme Generator

Used without parameters, it generates the layout inside the application.html.erb file using the default theme.

script/generate theme

You can specify the layout file name in the first parameter:

script/generate theme admin # it will generate a layout called `admin.html.erb`

If you want to use another theme, instead of the default, you can use the --theme option:

script/generate theme --theme="drastic-dark"

If you want to generate the stylesheets of a specific theme without changing the previously generated layout you can pass the --no-layout option:

script/generate theme --theme=bec --no_layout

You can specify the text used in the header with the --app-name option:

script/generate theme --app_name="My New Application"

If you need a layout for login and signup pages, you can use the --type option with sign as value. Ìf not specified, the default value is administration

script/generate theme --type=sign

Themed Generator

Start creating your controllers manually or with a scaffold, and then use the themed generator to overwrite the previously generated views.

If you have a controller named like the plural of the used model you can specify just the first parameter:

script/generate themed posts # you have a model named Post and a controller named PostsController

script/generate themed admin/gallery_pictures # you have a model named GalleryPicture and a controller named Admin::GalleryPicturesController

Use the --layout option specifying the previously generated layout to add a link to the controller you are working on:

script/generate themed posts --layout=admin # you will see the `Posts` link in the navigation

If the controller has a name different to the model used, specify the controller path in the first parameter and the model name in the second one:

script/generate themed items post

script/generate themed admin/items post

If you use will_paginate for pagination use the --with_will_paginate:

script/generate themed items post --with_will_paginate        

If you have something like map.resource :dashboard in your routes.rb file, you can use the --type=text to generate a view with just text:

script/generate themed homes --type=text

If you want to show form error messages inside the generated forms, use the following code inside your environment.rb

ActionView::Base.field_error_proc = do |html_tag, instance| 
  if html_tag =~ /<label/
    %|<div class="fieldWithErrors">#{html_tag} <span class="error">#{[instance.error_message].join(', ')}</span></div>|

If you want to have translated pages, simple create in your locale.yml the keys just like config/locales/en_us.yml example. en_us: web-app-theme: save: Save cancel: Cancel list: List edit: Edit new: New show: Show delete: Delete confirm: Are you sure? created_at: Created at all: All
