Could someone point me to an example of a Couchapp application that queries a view with a key based on user input from an HTML form?
I can't seem to either figure out how to do this or find an example on my own via google.
I figured it out:
If you're using evently, then in /evently/[whatever]/_changes, instead of a fixed query.json, you can replace it with a query.js where you can dynamically return a query, e.g.:
function() {
var key = /* ... */
// get your key from the appropriate source (jquery, current page's URL, etc)
return {
"view" : "recent-items",
"key" : key,
"limit" : 50
}
}

I want to override the item listing template file core/themes/classy/templates/dataset/item-list.html.twig for listing the fields field_slider_images as well as field_blog_tags respectively of their's multiple values of the field.
I have selected "Unordered List" in the view.
Please do check the attached image.
I have created following files :
item-list--field-blog-tags.html.twig
item-list--field-slider-images.html.twig
But, this is not rendered for the listing of the fields.
When I have created item-list.html.twig then only it will access.
However, both fields have different data to style and I am not able to get the current field name which is loading it's data in item-list.html.twig.
Had a brief look at this and it doesn't seem that 'item-list' to have suggestions, which is quite unfortunate.
In this situation there are two options:
Create your own suggestion which would accomplish exactly what you need.
You'll have to do something like this:
/
/*add new variable to theme with suggestion name*/
function hook_theme_registry_alter(&$theme_registry) {
$theme_registry['item_list']['variables']['suggestion'] = '';
}
//send a value to newly added variable to use it build the suggestion
function hook_ENTITY_TYPE_view(array &$build, $entity, $display, $view_mode) {
//add condition here if field exists or whatever, do the same for other field
$build['field_slider_images']['#suggestion'] = 'field_slider_images';
}
//use newly added variable to build suggestion
function hook_theme_suggestions_THEME_HOOK(array $variables) {//THEME_HOOK=item_list
$suggestions = array();
if(isset($variables['suggestion'])){
$suggestions[] = 'item_list__' . $variables['suggestion'];
}
return $suggestions;
}
Now you should be able to use item-list--field-slider-images.html.twig
Second option is to do what others in core did: use a new theme
function hook_ENTITY_TYPE_view(array &$build, $entity, $display, $view_mode) {
//add condition here if field exists or whatever, do the same for other field
$build['field_slider_images']['#theme'] = array(
'item_list',
'item_list__field_slider_images',
);
}
I have a custom form where, in a subtab, I have a dropdown that I need to find out the selected value on the client side after the user selects to perform some validation. I created the script and tied it to the on change event of the dropdown. I cannot seem to find the code to get the selected value on the client side. I have found code to read the value on the server side from a submit event. I need this on the client side on change. I am going to use the ID to look up a record and check a value on that record and if applicable popup a warning to the user. Either SS1 or SS2 is good, whatever would be better I have both available. Any help with this would be great. thanks
In a client script, you can use nlapiGetFieldValue() to retrieve the results.
function fieldchanged(type, name, linenum) {
if(name == 'dropdownid') {
var value = nlapiGetFieldValue('dropdownid');
alert(value);
}
}
OK the nlapiGetFieldValue, did not do the trick, what did was the following
function ValidateField( type, field, linenum ) {
if ( field === 'recordid' ) {
var vendorid = nlapiGetCurrentLineItemValue(type,field,linenum);
var vendorRecord = nlapiLoadRecord('vendor',vendorid);
}
return true;
}
thanks for your help
I need to save serial number of the document in a profile document and here is a code of action Execute Script:
if (document1.isNewNote()){
var pdoc:NotesDocument=database.getProfileDocument("LastNumber","")
var lnm=pdoc.getItemValue("lastNumber")[0];
var inputText6:com.ibm.xsp.component.xp.XspInputText = getComponent("inputText6");
inputText6.setValue(lnm);
pdoc.replaceItemValue("lastNumber",lnm);
pdoc.save();
}
This code is not opening profile document at all. Any thing wrong in the code?
"LastNumber" is the name of the form used to create Profile Document ?
this profile document already exist ?
there are no reader fields in this profile document ?
you have an error on this line : var pdoc:NotesDocument=database.getProfileDocument("LastNumber","") ?
or you have debug it and see that pdoc is null ?
instead of pdoc.getItemValue("lastNumber")[0] you can use pdoc.getItemValueInteger("lastNumber") to get a typed result
I supposed that this field contains a number and you want to increment it
instead of using inputText field you can set value directly with document1.setValue("NumberField", lnm);
I second the caution Per is suggesting. Profile documents can be a beast. You should abstract access to the "next number" into a SSJS function call. Btw. in your code snippet you don't actually increment the last number. Also: if your input text control is bound, go after the data source, not the UI.
A crude way (I would use a managed application bean for better isolation) for a better function could be this:
if(document1.isNewNote() {
document1.setValue("DocumentNumber",applicationTools.getNextNumber());
}
Then in a SSJS library you would have:
var applicationTools = {
"getNextNumber" : function() {
synchronized(applicationScope){
var pdoc:NotesDocument=database.getProfileDocument("LastNumber","");
if (!applicationScope.lastNumber) {
applicationScope.lastNumber = pdoc.getItemValueInteger("lastNumber");
}
applicationScope.lastNumber++;
pdoc.replaceItemValue("lastNumber",applicationScope.lastNumber);
pdoc.save(); //Make sure pdoc is writeable by ALL!!!!
pdoc.recycle();
return applicationScope.lastNumber;
}
},
"someOtherUtility" : function(nameToLookup, departments) {
// more stuff here
}
}
Which, in some way has been asked before, but not for a profile field. Someone still could simply go after the applicationScope.lastNumber variable, which is one of the reasons why I rather use a bean. The other: you could do the saving asynchronously, so it would be faster.
Note: in any case the number generation only works when you have a non-replicating database. But abstracting the function opens the possibility to replace fetching the number from the profile with a call to a central number generator ... or any other mechanism ... without changing your form again.
Looking at Str::slug for my frontend URL generation but just wondering how you guys go about implementing it with routes etc, for example, how would you guys go about changing http://www.example.com/courses/1 to http://www.example.com/courses/this-course
OK, I did it this way:
// I have a slug field in my courses table and a slug field in my categories table, along with a category_id field in my courses table.
// Route
Route::get('courses/{categorySlug}/{slug?}', function($categorySlug, $slug) {
$course = Course::leftJoin('categories', 'categories.id', 'courses.category_id')
->where('categories.slug', $categorySlug)
->where('courses.slug', $slug)
->firstOrFail();
return View::make('courses.show')->with('course', $course);
});
Works like a charm. It gets the $categorySlug and $slug variables then uses them to filter the Eloquent model Course to get the correct course object from the database.
EDIT: You can generate a URL in your view like:
http://www.example.com/courses/it-training/mcse
By doing something like:
{{ $course->title }}
A have a method in my Category like below that retrieves the parent category slug. This could be better achieved though using some sort of presenter class which would allow you to simply use $course->url but I haven't got around to doing this yet. I will update the answer when I do.
public function parentCategorySlug($parentId)
{
if ($parentId === '0')
{
return $this->slug;
}
return $this->where('id', $parentId)->first()->slug;
}
You can use the cvierbrock's Eloquent-Sluggable package.
As for me I created a helper function and used the following method taken from here.
public static function getSlug($title, $model) {
$slug = Str::slug($title);
$slugCount = count( $model->whereRaw("url REGEXP '^{$slug}(-[0-9]*)?$'")->get() );
return ($slugCount > 0) ? "{$slug}-{$slugCount}" : $slug;
}
You can create a related model Slug, and approach the course in your methods like so:
$course = Slug::where('slug', $slug) -> firstOrFail() -> course;
I have also implemented a similar URL mapping but I preferred to have both the ID and the slug in the requested URL, like this:
http://www.example.com/courses/1/my-laravel-course
This method allows me to get the requested course object from the ID given in the URL, rather than having to store the slugs in my DB table.
Route::post('courses/(:num)/(:any)', function ($courseid, $slug) {
$course = Course::where('id', '=', $courseid)->get();
return View::make('courses.show')->with('course', $course);
}
For Laravel 8:
Given my URL:
http://www.example.com/courses/this-course
My route:
Route::get('/courses/{course:slug}' , function(Course $course){
return view('showCourse' , [
'course' => $course
])
})
I'm displaying a list of articles in a page that are fetched using the Ember Data RESTAdapter. I need to implement a bootstrap'esque paginator (see: http://twitter.github.com/bootstrap/components.html#pagination) and cant seem to find a sane pattern for returning pagination data such as, page count, article count, current page, within a single request.
For example, I'd like the API to return something like:
{
articles: [{...}, {...}],
page: 3,
article_count: 4525,
per_page: 20
}
One idea was to add an App.Paginator DS.Model so the response could look like:
{
articles: [{...}, {...}],
paginator: {
page: 3,
article_count: 4525,
per_page: 20
}
}
But this seems like overkill to hack together for something so trivial. Has anyone solved this problem or found a particular pattern they like? Is there a simple way to manage the RESTAdapter mappings to account for scenarios such as this?
Try to use Ember Pagination Support Mixin and provide your own implementation of the following method. Instead of loading all the content, you can fetch the required content when the user is navigating the pages. All what you need initially is the total account of your records.
didRequestRange: function(rangeStart, rangeStop) {
var content = this.get('fullContent').slice(rangeStart, rangeStop);
this.replace(0, this.get('length'), content);
}
With ember-data-beta3 you can pass a meta-property in your result. The default RESTSerializer looks for that property and stores it.
You can access the meta-data like this:
var meta = this.get("store").metadataFor("post");
If you are not able to change the JSON returned from the server you could override the extractMeta-hook on the ApplicationSerializer (or any other Model-specific serializer).
App.ApplicationSerializer = DS.RESTSerializer.extend({
extractMeta: function(store, type, payload) {
if (payload && payload.total) {
store.metaForType(type, { total: payload.total }); // sets the metadata for "post"
delete payload.total; // keeps ember data from trying to parse "total" as a record
}
}
});
