Drupal Views: Remove actions(edit button) on drupal views from view_pre_render hook conditionally:
I am trying to hide/remove the edit button for few records conditionally on a view from the hook view_pre_render.
function member_management_views_pre_render(ViewExecutable $view) {
if ($view->id() == 'my_view_id') {
//if(mycondition){
foreach($view->field as $key => $value) {
//ACTIONS FIELD NAME IS OPERATIONS
//$value->_entity->operations->setValue() = 0;
//operations->field->handlers->displayhandlers
}
//}
}
}

I've inherited some work on an AdminLTE sidebar on a Django website. The page in question uses an "extends" block to load AdminLTE's index.html page right off the bat. Links on our treeview sidebar cause the entire page to reload, including the sidebar, so the state of any expanded treeview menus is lost whenever someone clicks a link.
I'm guessing there's some well-known way of making the sidebar keep its treeview menus open, but I've yet to find it. There are some working examples on the AdminLTE site, but I can't figure out how they work.
Can someone point me to the right piece of documentation to help me make my sidebar persistent across page loads?
Treeview css class works in an unordered list so any child links only show up when the parent list is clicked. An example of this is if you have "home" and then "About" "About-Locations". When you click About it is a tree-view class and on the sidebar it will show locations underneath it. When you click on home the locations sidebar link will not be displayed as this is how the css is written for the list.
The code can be found in the "AdminLTE.css" file.
I'm not working on django, I work on a MVC Razor app.
For the same problem, I use this solution :
I store the link clicked on the menu (ajax send to the server and session storage, but you can use cookie or what you want).
The link clicked is inserted in the java script below :
$(" ul.treeview-menu > li > a").on("click", function ()
{
if (this.href == "#")
return;
$.ajax({
type: "POST",
url: '/Outils/SetActiveMenu',
data: { url: this.href },
dataType: "json"
});
})
$(document).ready(function () {
var v = "#Html.Raw(Session["ActiveMenu"] == null?"": Session["ActiveMenu"].ToString())";
if(v == "") return;
var a = $('a[href="' + v + '"]');
openParentMenu(a);
a.css("background-color", "#E3E6E5");
});
function openParentMenu(item)
{
var parent = item.parent().closest("li.treeview");
if (parent.length != 0) {
openParentMenu(parent);
parent[0].children.item("a").click();
}
}
Here is the code for reference.
/* Tree()
* ======
* Converts the sidebar into a multilevel
* tree view menu.
*
* #type Function
* #Usage: $.AdminLTE.tree('.sidebar')
*/
$.AdminLTE.tree = function (menu) {
var _this = this;
var animationSpeed = $.AdminLTE.options.animationSpeed;
$(menu).on('click', 'li a', function (e) {
//Get the clicked link and the next element
var $this = $(this);
var checkElement = $this.next();
//Check if the next element is a menu and is visible
if ((checkElement.is('.treeview-menu')) && (checkElement.is(':visible')) && (!$('body').hasClass('sidebar-collapse'))) {
//Close the menu
checkElement.slideUp(animationSpeed, function () {
checkElement.removeClass('menu-open');
//Fix the layout in case the sidebar stretches over the height of the window
//_this.layout.fix();
});
checkElement.parent("li").removeClass("active");
}
//If the menu is not visible
else if ((checkElement.is('.treeview-menu')) && (!checkElement.is(':visible'))) {
//Get the parent menu
var parent = $this.parents('ul').first();
//Close all open menus within the parent
var ul = parent.find('ul:visible').slideUp(animationSpeed);
//Remove the menu-open class from the parent
ul.removeClass('menu-open');
//Get the parent li
var parent_li = $this.parent("li");
//Open the target menu and add the menu-open class
checkElement.slideDown(animationSpeed, function () {
//Add the class active to the parent li
checkElement.addClass('menu-open');
parent.find('li.active').removeClass('active');
parent_li.addClass('active');
//Fix the layout in case the sidebar stretches over the height of the window
_this.layout.fix();
});
}
//if this isn't a link, prevent the page from being redirected
if (checkElement.is('.treeview-menu')) {
e.preventDefault();
}
});
};
I have used the inbuilt functionality mentioned by #MDT and have created a function:
function toggleCollapsibleList(){
//Get the clicked link and the next element
var $this = $('#parent-list-item-id');
var checkElement = $('#an-id-for-collapsible-li-with-treeview-class');
//Check if the next element is a menu and is visible
if ((checkElement.is('.treeview-menu')) && (checkElement.is(':visible')) && (!$('body').hasClass('sidebar-collapse'))) {
//Close the menu
checkElement.slideUp(500, function () {
checkElement.removeClass('menu-open');
//Fix the layout in case the sidebar stretches over the height of the window
//_this.layout.fix();
});
checkElement.parent("li").removeClass("active");
}
//If the menu is not visible
else if ((checkElement.is('.treeview-menu')) && (!checkElement.is(':visible'))) {
//Get the parent menu
var parent = $this.parents('ul').first();
//Close all open menus within the parent
var ul = parent.find('ul:visible').slideUp(500);
//Remove the menu-open class from the parent
ul.removeClass('menu-open');
//Get the parent li
var parent_li = $this.parent("li");
//Open the target menu and add the menu-open class
checkElement.slideDown(500, function () {
//Add the class active to the parent li
checkElement.addClass('menu-open');
parent.find('li.active').removeClass('active');
parent_li.addClass('active');
//Fix the layout in case the sidebar stretches over the height of the window
});
}}
This worked for me :)
I have been following the tutorial at ionic2 SearchBar to work on the filter functionality.
The question is, I am not able to figure out how to get onCancel and onClear to work.
Steps:
1) Enter some keywords in SearchBar. It calls the onInput event and I get the value from searchItem.target.value unlike in tutorial which just uses searchItem.value
2) Now i try to click on clear "x" or Cancel button and it calls the onClear/onCancel event which is immediately followed by onInput event. And during this call, it does not find the searchItem.target.value and results in undefined due to which it breaks the functionality.
Can anyone provide more in depth details on how this works?
i fixed it in tutorial sample for ionic2 by stopping onClear event propagation
import {Component} from '#angular/core';
#Component({
selector: 'my-search',
template: '<ion-toolbar primary><ion-searchbar (input)="onInput($event)" (ionClear)="onClear($event)"></ion-searchbar></ion-toolbar><ion-content><ion-list><ion-item *ngFor="let item of items">{{ item }}</ion-item></ion-list></ion-content>'
})
export class HomePage {
items = [];
constructor() {
this.initializeItems();
}
initializeItems() {
this.items = [
'Angular 1.x',
'Angular 2',
'ReactJS',
'EmberJS',
'Meteor',
'Typescript',
'Dart',
'CoffeeScript'
];
}
onClear(ev)
{
this.initializeItems();
ev.stopPropagation();
}
onInput(ev) {
// Reset items back to all of the items
this.initializeItems();
// set val to the value of the searchbar
var val = ev.target.value;
// if the value is an empty string don't filter the items
if (val && val.trim() != '') {
this.items = this.items.filter((item) => {
return (item.toLowerCase().indexOf(val.toLowerCase()) > -1);
})
}
}
}
In Django admin, there is a drop down list for actions.
What I want to achieve is to get rid of the drop down list, and 'Go' button, and instead, display my actions as buttons.
How can it be done? Thanks in advance.
Create a js file action_buttons.js inside your static directory
(function ($) {
function fix_actions() {
var container = $('div.actions');
if (container.find('option').length < 10) {
container.find('label, button').hide();
var buttons = $('<div></div>')
.prependTo(container)
.css('display', 'inline')
.addClass('class', 'action-buttons');
container.find('option:gt(0)').each(function () {
$('<button>')
.appendTo(buttons)
.attr('name', this.value)
.addClass('button')
.text(this.text)
.click(function () {
container.find('select')
.find(':selected').attr('selected', '').end()
.find('[value=' + this.name + ']').attr('selected', 'selected');
$('#changelist-form button[name="index"]').click();
});
});
}
};
$(function () {
fix_actions();
});
})(django.jQuery);
Copy above code to js file
In you admin.py under admin class add
class Media:
js = ('path/to/action_buttons.js', )
I couldn't find a street way to do it.
I couldn't find a street way to do it, so I make tweak with JavaScript to do it.
$(document).ready(function() {
$(".field-current").live("click",function(){
$action = $($(this).children()[0])
current_state = $action.is(':checked');
$('.field-current').each(function(index) {
var $temp = $($(this).children()[0])
$temp.val(false);
$temp.attr('checked', false);
});
var $current = $($(this).children()[0])
if (current_state == "on" || current_state == true){
$current.val(true);
$current.attr('checked', true);
}else{
$current.val(false);
$current.attr('checked', false);
}
});
});
in the admin page add
class ArticleDetailsInlineAdmin(admin.TabularInline):
....
fields = ['current', 'slug','summary','mod_date']
class ArticleHeaderAdmin(admin.ModelAdmin):
inlines = [ArticleDetailsInlineAdmin,]
......
form = ArticleForm
class Media:
js = ('js/admin-current-article.js')
by doing this the current field will act like radio button among the inlineadmin
Try using the formfield_overrides property to change the widget used (it's available on InlineAdmin classes as well as ModelAdmin):
from django.forms.widgets import RadioSelect
class ArticleDetailsInlineAdmin(admin.TabularInline):
...
fields = ['current', 'slug', 'summary', 'mod_date']
formfield_overrides = {
models.BooleanField: {'widget': RadioSelect},
}
Note this will use radio buttons instead of checkboxes for all BooleanFields in ArticleDetailsInlineAdmin.
When I put my boolean field in list_editable, it's icon change from the nice on/off icon to the legacy checkbox. Is there a way to keep the field editable with the nice icons ?
I think I've already done this, but can't remember how...
Use you own JavaScript to replace the checkbox with the appropriate image, and use click events to change the image and set the checkbox appropriately.
CSS
.hidden {
position:absolute;
left:-99999px;
width:0;
height:0;
overflow:hidden;
}
JS
(function($){
var on_image = '/static/admin/img/admin/icon-yes.gif';
var off_image = '/static/admin/img/admin/icon-no.gif';
$(document).ready(function(){
var $checkbox = $('.checkbox_field input');
// Can't simply `hide()` as its value will not be posted
$checkbox.addClass('hidden');
var $img = $('<img/>');
if ($checkbox.attr('checked')) {
$img.attr('href', on_image);
$img.attr('alt', 'On');
} else {
$img.attr('href', off_image);
$img.attr('alt', 'Off');
}
$img.insertAfter($checkbox);
$img.click(function(){
var $img = $(this);
var $checkbox = $img.siblings('input');
if ($img.attr('href') == on_image) {
$img.attr('href', off_image);
$img.attr('alt', 'Off');
$checkbox.attr('checked', false);
} else {
$img.attr('href', on_image);
$img.attr('alt', 'On');
$checkbox.attr('checked', true);
}
});
});
)(django.jQuery);
