Availability table using Laravel Backpack - laravel-backpack

Is it possible to archive the functionality like this?
The table schema is:
Schema::create('availability_general', function (Blueprint $table) {
$table->id();
$table->integer('user_id');
$table->integer('day_of_the_week');
$table->time('from');
$table->time('to');

You can achieve part of that functionality using the repeatable field - https://backpackforlaravel.com/docs/4.1/crud-fields#repeatable-1 , not sure if everything though.
But since this interface is so peculiar, I recommend coding your own thing for this bit - you'll be better off. Either by creating a custom field type https://backpackforlaravel.com/docs/4.1/crud-fields#creating-a-custom-field-type-1 or a custom operation https://backpackforlaravel.com/docs/4.1/crud-operations#documentation-box

Override Sails.js Waterline intercept Find method

I have a model named Product.
I want configurable across the board filtering for this model.
For example: sails.config.field = 2;
When I do GET /Product I want it to essentially do GET /Product?where={"field": 2}
The above works for blueprint by adding a policy, but I want consistent behavior when I use the waterline ORM
GET /Product
and Product.find() should return the same thing.
I can override the model: Product.find and it would work perfectly... IF there was some way for me to access the underlying find code.
The code I am using to intercept the blueprint is:
if (!req.query.where) {
req.query.where = `{"status":{">":0,">=":${sails.config.catalogVersions.status}}}`;
} else {
const parsedWhere = JSON.parse(req.query.where);
parsedWhere.status = {
'>': 0,
'>=': sails.config.catalogVersions.status,
};
req.query.where = JSON.stringify(parsedWhere);
}
I could very easily apply this to a Model.find interceptor.
Is there any way that once sails is loaded, I can access the root find method on a model even if its been overwritten at load time?
Maybe you could think on something like this one:
https://github.com/muhammadghazali/sails-hook-pagination
It's a hook and maybe works for your intended use.
I ended up using the hook:orm:loaded hook, to run some code which monkeypatched all of the models with a defaultScope which was stored in each of my models. It works well as I can easily modify the default criteria on all of the models and get consistent behavior across blueprint and waterline.
For code see:
Is there a way to override sails.js waterline endpoint with custom controller, but keep built in pagination, and filtering?

How to turn OFF Schema Validations dynamically using MongoDB-JAVA APIs

I have created a collection with schema validation as below,
ValidationOptions collOptions = new ValidationOptions();
collOptions.validator(sdoc);
collOptions.validationLevel(ValidationLevel.MODERATE);
collOptions.validationAction(ValidationAction.WARN);
srdmDatabase.createCollection(collectionName,new CreateCollectionOptions().validationOptions(collOptions));
My collection is created successfully with schema validation.
In some cases, I want to turn OFF the validation check dynamically.
I found that there is an option to turn OFF the validation(ValidationLevel.OFF) in monogdb-java-driver, but I have no idea about how to use this option.
Please help me some one how to turn off the validation check programmatically.
We are using MongoDB-4.0 and mongo-java-driver-3.10.2.
Thanks in advance.
You can try using the following code to bypass the validation.
For updates
collection.updateOne(
Filters.eq("_id", 1),
Updates.set("name", "Fresh Breads and Tulips"),
new UpdateOptions().upsert(true).bypassDocumentValidation(true));
Similarly for inserts, you can use InsertOptions.bypassDocumentValidation(true)
Refer this link for more info https://docs.mongodb.com/manual/core/schema-validation/#bypass-document-validation

SAPUI5 bindAggregation complete for a Table

I am binding an aggregation to a table . I couldn't find an event which is triggered after the binding is complete . There is "updateFinished" event for sap.m.List , which is exactly what I am looking for in a Table (and a dropodown). I thought of using attachRequestCompleted() on the model , but the model is used at other places where I do not want this event to trigger.
Is there anyway to trigger a event once the databinding is complete on a Table (and a dropdown)?
Any help is appreciated.
Thanks in advance.
update: There is "updateFinished" event for table extended from ListBase. I am still not sure how I missed it before I posted this question. But, the question is still valid for a dropdown and TableSelectDialog controls.
I also stumbled upon that problem, but in a different Context.
I have a Grid layout in which I dynamically load Panels via an oData Model.
Therefore I have entered the path in my XML Grid-View element.
<l:Grid id="grid" content="{some path...}">...</l:Grid>
Now I wanted to set the grid view busy and when the data is loaded revert this.
Therefore I use the Binding of the grid view.
In the Controllers onInit method I have added:
this._oGrid = this.getView().byId("grid");
this.getRouter().attachRouteMatched(this._onRouteMatch.bind(this));
Please note that the bind method is not available in every browser. You need to apply a polyfill. (See https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Function/bind)
Also Bind has nothing to do with the binding :D
I needed to do this because the Binding is not available in the onInit function.
The _onRouteMatched function:
var oContent = this._oGrid.getBinding("content");
oContent.attachDataReceived(function(oData) {
this._oGrid.setBusy(false);
}.bind(this));
Now when the data is received the busy option is set to false.
If you want to show a 'loading' indicator for your table while the data is still loading (and thus not bound), I think the best approach is the following:
Use a dedicated JSONModel which holds only UI-specific stuff, like toggling enabled/readonly/busy/etc properties of controls.
In your case, something like:
var oUIModelData = {
tableIsBusy : false,
//etc, things like :
btnSubmitEnabled : false,
someControlVisible : true
};
var oUIModel = new sap.ui.model.json.JSONModel();
oUIModel.setData(oUIModelData);
sap.ui.getCore().setModel(oUIModel, "UIModel");
In your table definition, bind the busy property to {UIModel>/tableIsBusy} and set the table's property busyIndicatorDelay to 0 to avoid any delays
Just before you do your OData service call, set the property tableBusy to true. This will immediately show the busy overlay to your table:
sap.ui.getCore().getModel("UIModel").setProperty(tableIsBusy, true);
//here your OData read call
In your OData service's requestCompleted (and if needed, also in requestFailed) event handlers, set the busy property of the UIModel back to false:
sap.ui.getCore().getModel("UIModel").setProperty(tableIsBusy, false);
The big benefit of this approach is (IMHO) instead of relying on each control to check whether the data has been loaded, simply do it during the actual load.
And by binding these UI-related things to a (separate) model saves you from writing lots of extra code ;-)
In general you could solve the problem by using batch processing on the OData service. According to https://sapui5.netweaver.ondemand.com/docs/guide/6c47b2b39db9404582994070ec3d57a2.html:
Use OData model v2.
var oModel = new sap.ui.model.odata.v2.ODataModel(myServiceUrl);
Define a set of deferred batch groups.
oModel.setDeferredBatchGroups(["myGroupId", "myGroupId2"]);
Add the batch group information to the corresponding bindings, e.g:
{
path:"/myEntities",
parameters: {
batchGroupId: "myGroupId"
}
}
All read/query actions on bindings in a certain batch group will be held back until a .submitChanges(.) call on the batch group is made.
oModel.submitChanges({
batchGroupId: "myGroupId",
success: mySuccessHandler,
error: myErrorHandler
});
Use the success/error handlers to execute actions.
This rather generic approach gives you additional control such as trigger actions, grouping and event handling on the OData model.

Prevent form manipulation in Lithium/mongoDB

I'm writing my first community page with Lithium and mongoDB. I really like the schema-less way of mongo, but there is one problem making it impossible working without a schema:
For instance we have a simple form like this:
<?=$this->form->create();?>
<?=$this->form->field('name',array('label' => 'Topic title'));?>
<?=$this->form->field('text',array('label' => 'Content'));?>
<?=$this->form->submit('create');?>
which will be even simpler saved by this:
if($this->request->is('post')) {
$board_post = BoardPosts::create($this->request->data);
$board_post->save();
}
Now it's possible for everyone to add some form inputs by DOM manipulation with Firebug, Developer Tools etc. Of course that it might be some sensless fields in the database, but maybe someone adds a field, that is really used.
The only way to prevent this, is creating a schema in model. But for me this makes the whole idea of a schema-less database useless, doesn't it? And how to make schemas for different situations/actions, when some fields must not occur?
The Model::save() method accepts a 'whitelist' param in its options. See http://li3.me/docs/lithium/data/Model::save()
$whitelist = array(
'title',
'text'
);
$post = BoardPosts::create();
$post->save($this->request->data, compact('whitelist'));
You can also define protected $_schema in your Model and set protected $_meta = array('locked' => true); which will automatically set the whitelist to the fields defined in your schema. However, it is a good idea to define the whitelist in your controller to avoid attacks like you describe.
This problem is called a mass-assignment vulnerability and exists in many frameworks if developers are not careful.

Zend Framework / Form Element is rendering as a text box rather than a dropdown box

I have the following in a config.ini file: (Zend_Form_Element)
site_status.name = "site_status"
site_status.type = "select"
site_status.label = "Status"
site_status.options.multiOptions.active.key = "Active"
site_status.options.multiOptions.active.value = "Active"
site_status.options.multiOptions.active.key = "Inactive"
site_status.options.multiOptions.active.value = "Inactive"
As you can see this is supposed to be a dropdown (select) box, however it is being rendered as a standard text box. What am I doing wrong?
--> Edit
Rather than tying the elements to a form, I am trying to tie them to a database: In my code it would look something like this:
[{tablename}] // the table name would represent a section in the ini
{column}.name = "{column_name/form_field_id}";
{column}.type = "{form_element_type}"
{column}.label = "{form_element_label}"
...
From there I would pull in the database table(s) that the form would represent data for (one or more tables as necessary). As far as the reasoning for this approach is that (down the road), I want to define (either by ini or some other storage method), a configuration file that would be a list of fields/elements that belong to a specific form (that a non-programmer type could easily edit), that the 'generic' form class would read, pull in the element info, and create the form on the fly.
I do realize however this poses another problem which I haven't yet figured out, and that is how to use table lookups for select elements (without coding the database retrieval of the lookup into the form, so that a non-user could easily just define it without any programming, purely configuration, but that is a whole other topic not part of my question here. (and I think I have viable ideas/solutions to that part of the problem anyhow) -- extra config entries and a generic routine pretty much.
I hope that clarifies my thought process and reason why I am doing it the way I am in the example above.
I have not yet played with using a Zend_Config to construct an instance of Zend_Form.
But a look at the code suggests that Zend_Form::addElement() doesn't directly take a Zend_Config instance as a param. Rather, it looks like you need pass your Zend_Config instance to the form constructor. It also seems that the config format needs to be a little deeper in order to map config keys to setXXX() calls.
In path/to/config/myForm.ini:
[myForm]
myForm.elements.site_status.name = "site_status"
myForm.elements.site_status.type = "select"
myForm.elements.site_status.label = "Status"
myForm.elements.site_status.options.multiOptions.active.key = "Active"
myForm.elements.site_status.options.multiOptions.active.value = "Active"
myForm.elements.site_status.options.multiOptions.inactive.key = "Inactive"
myForm.elements.site_status.options.multiOptions.inactive.value = "Inactive"
Then instantiating:
$formConfig = new Zend_Config_Ini('path/to/config/myForm.ini', 'myForm');
$form = new Zend_Form($formConfig);
Not tested, but looking at this example:
Using Zend_Form with Zend_Config - Andrew Vayanis
it feels like it should go something like the above.
Update
In view of the comments/feedback from #Aaron, two more approaches.
We could extend Zend_Form, implementing a method called something like addElementByConfig in which we would pass the shallow Zend_Config instance that describes the element itself. In fact, we could even just override addElement(), taking a recursive approach: if the first param is an instance of Zend_Config, then call addElement() using the component data.
If the atomicity and re-usability are the primary benefits we seek in using Zend_Config to describe an element, then perhaps we just make a custom element extending Zend_Form_Element. Then we could use these elements in any forms we wish.
