View construction (and tools)
|
|
==============================
|
|
|
|
Although most of our code base is being processed server side, some things just require interaction on the
|
|
clients machine for a fluent user experience.
|
|
|
|
In this chapter we will try to explain some of the components we use when designing pages and how pages are usually constructed.
|
|
|
|
--------------------------
|
|
Layout
|
|
--------------------------
|
|
|
|
To ease reading of volt templates, we recommend using a fixed layout when creating templates.
|
|
The base of our rendered page always contains the standard `layout <https://github.com/opnsense/core/blob/master/src/opnsense/mvc/app/views/layouts/default.volt>`__
|
|
which is hooked via our standard frontend controller.
|
|
|
|
Below you will find the sections and their order, which we will describe briefly.
|
|
|
|
.. code-block:: html
|
|
|
|
{#
|
|
{1} Copyright notice
|
|
#}
|
|
<script>
|
|
$( document ).ready(function() {
|
|
{2} UI code
|
|
});
|
|
</script>
|
|
{3} page html
|
|
{{ partial("layout_partials/base_dialog",...)}} {4} dialog forms (see getForm())
|
|
|
|
|
|
#. The copyright block, 2 clause BSD with the authors on top
|
|
#. Javascript code which belongs to this page
|
|
#. HTML code, usually starts with some :code:`<div>` containers and uses standard Bootstrap 3 layouting
|
|
#. When forms are used, these are placed last, these will be generated to the client as standard html code
|
|
|
|
|
|
----------------------------
|
|
ajaxCall
|
|
----------------------------
|
|
|
|
:code:`ajaxCall(url, sendData, callback)` is a wrapper around jQuery's :code:`$.ajax` call preset to a :code:`POST` type
|
|
request and wrapping the sendData into a json object.
|
|
The :code:`callback` function will be called with the data and status received from the endpoint.
|
|
|
|
|
|
|
|
.. code-block:: javascript
|
|
:name: ajaxCall
|
|
:caption: example usage
|
|
|
|
ajaxCall('/api/monit/status/get/xml', {}, function(data, status) {
|
|
console.log(data)
|
|
});
|
|
|
|
|
|
----------------------------
|
|
ajaxGet
|
|
----------------------------
|
|
|
|
:code:`ajaxGet(url,sendData,callback)` is also a wrapper around jQuery's :code:`$.ajax` call, but for a :code:`GET` type
|
|
request.
|
|
|
|
.. code-block:: javascript
|
|
:name: ajaxGet
|
|
:caption: example usage
|
|
|
|
ajaxGet('/api/diagnostics/interface/getInterfaceNames', {}, function(data, status) {
|
|
console.log(data);
|
|
});
|
|
|
|
|
|
----------------------------
|
|
mapDataToFormUI
|
|
----------------------------
|
|
|
|
The :code:`mapDataToFormUI(data_get_map, server_params)` can be used to map data retrieved from a controller to a
|
|
form in the browser.
|
|
|
|
This function accepts two parameters, data_get_map contains a mapping between form id's and server endpoints, server_params
|
|
is optional and can be used to set option in the :code:`GET` type request.
|
|
|
|
When the endpoint is successfully called it should return a json type structure containing the path to the item, as an
|
|
example using :code:`data_get_map = {'myform': '/api/path/to/formdata'};`:
|
|
|
|
|
|
.. code-block:: json
|
|
|
|
{
|
|
"netflow": {
|
|
"capture": {
|
|
"interfaces": {
|
|
"lan": {
|
|
"value": "LAN",
|
|
"selected": 1
|
|
},
|
|
"wan": {
|
|
"value": "WAN",
|
|
"selected": 0
|
|
}
|
|
},
|
|
},
|
|
"collect": {
|
|
"enable": "1"
|
|
}
|
|
}
|
|
}
|
|
|
|
Which maps to the fields in this simplified structure (usually rendered via our volt templates):
|
|
|
|
.. code-block:: html
|
|
|
|
<form id="myform">
|
|
<select multiple="multiple" id="netflow.capture.interfaces">
|
|
</select>
|
|
<input type="checkbox" id="netflow.collect.enable">
|
|
</form>
|
|
|
|
|
|
The function returns a :code:`$.Deferred()` which will be resolved when all endpoints are called.
|
|
|
|
----------------------------
|
|
saveFormToEndpoint
|
|
----------------------------
|
|
|
|
:code:`saveFormToEndpoint(url, formid, callback_ok, disable_dialog, callback_fail)` is the opposite of :code:`mapDataToFormUI()`
|
|
and retrieves the data from the form and sends it to the configured (url) endpoint as json structure.
|
|
|
|
The response data looks similar to the example data in mapDataToFormUI, but more condensed since selections will
|
|
be returned as single (separated) values, such as :code:`lan,wan` if both options where set.
|
|
|
|
|
|
----------------------------
|
|
updateServiceControlUI
|
|
----------------------------
|
|
|
|
The code:`updateServiceControlUI(serviceName)` function hooks the service control on top of the standard template, where you can find
|
|
the [re]start, stop and status of the service.
|
|
|
|
It assumes the following endpoints exists for the module:
|
|
|
|
* /api/{{serviceName}}/service/status
|
|
* returns the status of the service (running, stopped) in a field named "status"
|
|
* /api/{{serviceName}}/service/start
|
|
* start the service
|
|
* /api/{{serviceName}}/service/restart
|
|
* restart the service
|
|
* /api/{{serviceName}}/service/stop
|
|
* stop the service
|
|
|
|
|

|
|
Dialog wrappers
|
|
----------------------------
|
|
|
|
We are using `BootstrapDialog <https://nakupanda.github.io/bootstrap3-dialog/>`__ to display standard dialogs, to limit
|
|
the boilerplates needed to show these dialog we added the following wrapper funcitons:
|
|
|
|
|
|
stdDialogInform(title, message, close, callback, type, cssClass)
|
|
..............................................................................................
|
|
|
|
Informational dialog with a single close button, using the following parameters:
|
|
|
|
* title: :code:`string` dialog title
|
|
* message: :code:`string` dialog message
|
|
* close: :code:`string` close button text
|
|
* callback: :code:`function()` to be called after close
|
|
* type: :code:`string` dialog type. one of : danger, default, info, primary, success, warning
|
|
* cssClass: :code:`string` css class to use
|
|
|
|
|
|
stdDialogConfirm(title, message, accept, decline, callback, type)
|
|
..............................................................................................
|
|
|
|
Ok/Cancel dialog type using the following parameters:
|
|
|
|
* title: :code:`string` dialog title
|
|
* message: :code:`string` dialog message
|
|
* accept: :code:`string` accept button text
|
|
* decline: :code:`string` decline button text
|
|
* callback: :code:`function()` to be called after close
|
|
* type: :code:`string` dialog type. one of : danger, default, info, primary, success, warning
|
|
|
|
|
|
|
|
stdDialogRemoveItem(message, callback)
|
|
..............................................................................................
|
|
|
|
Simple remove item (warning) dialog, using a message and optionally a callback.
|
|
|
|
----------------------------
|
|
$.SimpleActionButton
|
|
----------------------------
|
|
|
|
Using the jQuery extension :code:`SimpleActionButton` one can register simple ajax calls on components click events, which
|
|
will call the selected endpoint and show a progress animation (spinner) to the user.
|
|
|
|
The following parameters can be supplied as data attributes on the target object:
|
|
|
|
* endpoint : endpoint to call (e.g. :code:`/api/my/action`)
|
|
* label : button label text
|
|
* service-widget : the service widget to refresh after execution, see :code:`updateServiceControlUI()`
|
|
* error-title : error dialog title
|
|
|
|
The method itself can be feed with callbacks to call before (:code:`onPreAction()`) and after (:code:`onAction()`) execution.
|
|
|
|
An example of a button could look like this:
|
|
|
|
.. code-block:: html
|
|
|
|
<button class="btn btn-primary" id="reconfigureAct"
|
|
data-endpoint='/api/component/service/reconfigure'
|
|
data-label="{{ lang._('Apply') }}"
|
|
data-service-widget="component"
|
|
data-error-title="{{ lang._('Error reconfiguring component') }}"
|
|
type="button"
|
|
></button>
|
|
|
|
To utilize the callbacks, one could use:
|
|
|
|
.. code-block:: html
|
|
|
|
$('#btnTest').SimpleActionButton({
|
|
onPreAction: function() {
|
|
const dfObj = new $.Deferred();
|
|
console.log("called before endpoint execution, returning a promise.");
|
|
return dfObj;
|
|
},
|
|
onAction: function(data, status){
|
|
console.log("action has been executed.");
|
|
}
|
|
});
|
|
|
|
|
|
----------------------------
|
|
$.UIBootgrid
|
|
----------------------------
|
|
|
|
The UIBootgrid jQuery extension is a wrappper around a slightly modified `jquery-bootgrid <http://www.jquery-bootgrid.com/>`__
|
|
component, the pattern we implement with our wrapper is inspired by `this <http://www.jquery-bootgrid.com/Examples#command-buttons>`__ example.
|
|
|
|
|
|
Defining the html table is best explained in the jquery-bootgrid examples, our wrapper eases the implementation of the javascript code.
|
|
|
|
The minimal implementation contains a reference to the search endpoint which should return a json resultset containing :code:`rows`
|
|
and pagination data (:code:`current`, :code:`rowCount`, :code:`total`).
|
|
|
|
.. code-block:: html
|
|
|
|
$("#my_grid").UIBootgrid(
|
|
{ search:'/api/path/to/search',
|
|
get:'/api/path/to/get',
|
|
set:'/api/path/to/set',
|
|
add:'/api/path/to/add',
|
|
del:'/api/path/to/del',
|
|
toggle:'/api/path/to/toggle',
|
|
info:'/api/path/to/info'
|
|
}
|
|
);
|
|
|
|
|
|
The other optional endpoints are either used to populate a form, as defined in the :code:`data-editDialog` property on the table or
|
|
can be used to feed actions, such as **set** (set new values, return validation errors), **add** a new record, **del** an existing record
|
|
or **toggle** if the record should be enabled or disabled. :code:`info` endpoints are not used very often (and can safely be omitted), these are mainly intended as simple trigger to display an info dialog.
|
|
|
|
|
|
A full example of a basic grid is available in our :doc:`../examples/using_grids` example
|
|
|
|
In some cases the developer wants to signal the user about the fact that changes need to be applied in order to be active, for this scenario one can use the :code:`data-editAlert`
|
|
property of the table, which offers the ability to show an alert after changes. Below example would be shown when the table tag contains :code:`data-editAlert="exampleChangeMessage"`
|
|
|
|
.. code-block:: html
|
|
|
|
<div id="exampleChangeMessage" class="alert alert-info" style="display: none" role="alert">
|
|
{{ lang._('After changing settings, please remember to apply them with the button below') }}
|
|
</div>
|
|
|
|
|
|
.. Tip::
|
|
|
|
You can access the general settings of the jquery-bootgrid plugin using the :code:`options` property, which can be convenient when you would like to change
|
|
requests or responses as being exchanged with the server. The available options are described `here <http://www.jquery-bootgrid.com/Documentation#table>`__
|
|
|
|
|
|
OPNsense settings
|
|
.......................
|
|
|
|
We added a couple of settings to the list, which help to extend our plugin a bit more easily. Below we will explain which settings (within the options tag) are added by us:
|
|
|
|
* useRequestHandlerOnGet
|
|
|
|
* Boolean value which enables the use of the request handler when a :code:`get` request is executed ot fetch data for the dialog. This can be used to add parameters to the request.
|
|
|
|
* onBeforeRenderDialog
|
|
|
|
* function handler which will be called before an edit dialog is being displayed, can be used to change the otherwise static dialogs. Should return a $.Deferred() object. (e.g. :code:`return (new $.Deferred()).resolve();`)
|
|
|
|
|
|
Formatters
|
|
.......................
|
|
|
|
Formatters can be used in the grid heading to choose the presentation of an attribute, we include a couple of standard formatters which are:
|
|
|
|
* commands (commands list, edit,copy and delete)
|
|
* commandsWithInfo (same as commands, but with an info button as well)
|
|
* rowtoggle (show enabled status and act as toggle button)
|
|
* boolean (show boolean value)
|
|
|
|
|
|
|
|
Visible columns
|
|
......................
|
|
|
|
jquery-bootgrid offers the ability to add columns which are not visible by default using the :code:`data-visible` tag. When
|
|
using our wrapper, these can be used to set defaults as well,
|
|
but the users last selection is also recorded in its local browser storage as well as the number of results shown in the grid when opening the same page again.
