Public Pages Configuration

Starting from Agate 2.0, the administration user interface is distinct from the public pages, i.e. pages that are to be accessed by regular users. These pages are based on templates that can be customized, extended or overridden. The template engine that is used is FreeMarker which has a clean and powerful syntax.

Page Templates

Main Pages

The main public pages are:

Page Description
index The home page
profile The user profile page for updating personal information and password
signin The login page
signup The user registration page
signup-with The user registration page, with form pre-filled with personal information extracted from a OpenID Connect server
confirm The page to confirm user’s registration (and validate email) and set the user password
forgot-password The page to ask for password reset
reset-password The page to update the password after a reset was triggered
just-registered The welcome page after a user has registered

The templates structure is organized in a way that it should not be necessary to override these pages definitions. Instead of that, it is recommended to change/extend the theme/style as described in this guide.

Some template variables (date formats, branding, favicon etc.) are also defined in libs/settings.ftl and can be altered in the file models/settings.ftl that would be added in your configuration folder as follows:

└── conf
    └── templates
        └── models
            └── settings.ftl

General settings

Variable Description
datetimeFormat The format in which the date-time values should be rendered.
date The format in which the date values should be rendered.
faviconPath The location of the favicon, to be modified to match your own.
brandImageSrc The location of your organization’s logo.
brandImageClass CSS classes to apply to the logo.
brandTextEnabled Logical to show/hide a text aside of the logo.
brandTextClass CSS classes to apply to the text aside of the logo.
adminLTEPath The location of the AdminLTE theme if this one has been modified (see the Theme section in this documentation).

Home page settings

Variable Description
portalLink The link applied to the logo. Default is the data portal (as specified in the Administration > General section), but it could also be the organization’s main portal.

User Profile page settings

Variable Description
showProfileRole Logical to show/hide the role to which the user belongs.
showProfileGroups Logical to show/hide the groups to which the user belongs.
showProfileApplications Logical to show/hide the applications in which the user can sign.

Adding Pages

It is possible to add new pages, for providing additional information or guidance to the regular user. This can be done as follows:

  • Install a new page templates
  • Add a new menu entry

1. Install custom page template

The new template page is to be declared in the configuration folder:

└── conf
    └── templates
        └── custom.ftl

You can check at the provided templates to make your template fit in the site theme and structure. The profile page template could be a good starting point.

FreeMarker will look at its context to resolve variable values. For a custom page the objects available in the context are:

Object Description
config The Agate configuration
user The user object (if user is logged in)
query The URL query parameters as a map of strings

This custom template page can load any CSS or JS file that might be useful. These files can be served directly by adding them as follows (there are no restrictions regarding the naming and the structure of these files, as soon as they are located in the static folder):

└── conf
    └── static
        ├── custom.css
        └── custom.js

The URL of this custom page will be for instance:

2. Custom menu entry

To link to a custom page (or an external page), some templates can be defined to extend the default menus: left menu can be extended on its right and right menu can be extended on its left. The corresponding templates are:

└── conf
    └── templates
        └── models
            ├── navbar-menus-left.ftl
            └── navbar-menus-right.ftl

Check at the default left and right menus implementation as a reference.

Theme and Style


The default theme is the one provided by the excellent AdminLTE framework. It is based on Bootstrap and JQuery. In order to overwrite this default theme, the procedure is the following:

  • Build a custom AdminLTE distribution
  • Install this custom distribution
  • Change the template settings so that pages refer to this custom distribution instead of the default one

1. Build custom AdminLTE

This requires some knowledge in CSS development in a Node.js environment:

  • Download AdminLTE source (source code or a released version)
  • Reconfigure Sass variables
  • Rebuild AdminLTE (see instructions in the README file, contributions section)

2. Install custom AdminLTE

The objective is to have the web server to serve this new set of stylesheet and javascript files. This is achieved by creating the folder AGATE_HOME/conf/static and copying the AdminLTE custom distribution in that folder. Not all the AdminLTE are needed, only the dist and plugins ones. The folder tree will look like:

└── conf
    └── static
        └── admin-lte
            ├── dist
            └── plugins

3. Template settings

Now that the custom AdminLTE distribution is installed in the web server environment, this new location must be declared in the page templates. The default templates settings are defined in the libs/settings.ftl template file. See the adminLTEPath variable. This variable can be altered by defining a custom settings.ftl file as follows:

└── conf
    └── templates
        └── models
            └── settings.ftl

In this custom settings.ftl file the new AdminLTE distribution location will be declared:

<#assign adminLTEPath = "/admin-lte"/>


As an alternative to theming, it is also possible to alter the style of the pages by loading your own stylesheet and tweaking the pages’ layout using javascript (and JQuery). The procedure is the following:

  • Install custom CSS and/or JS files
  • Custom the templates to include these new CSS and/or JS assets

1. Install custom CSS/JS

The objective is to have the web server to serve this new set of stylesheet and javascript files. This is achieved by creating the folder AGATE_HOME/conf/static and copying any CSS/JS files that will be included in the template pages. The folder tree will look like:

└── conf
    └── static
        ├── custom.css
        └── custom.js

2. Custom templates

For the CSS files, the models/head.ftl template allows to extend the HTML pages “head” tag content with custom content. For the JS files, the models/scripts.ftl template allows to extend the HTML pages “script” tags. The folder tree will look like:

└── conf
    └── templates
        └── models
            ├── head.ftl
            └── scripts.ftl

Where the head.ftl template will be:

<link rel="stylesheet" href="/custom.css"/>

And the scripts.ftl template will be:

<script src="/custom.js"/>


The translations are performed in the following order, for a given locale:

  1. check for the message key in the messages_<locale>.properties (at different locations)
  2. check for the message key in the <locale> JSON object as defined the Administration > Translations section of the administration interface

For the messages_* properties, the translations can be added/overridden as follows:

└── conf
    └── translations
        ├── notifications
        │   ├──
        │   └──

Note that the notification emails translations are located at a different place than the ones for the public pages. Note also that you can declare only the messages_* properties files that are relevant (language and public pages vs. notification emails) and the content of these files can contain only the translation keys that you want to override.
