I have a project that sells products.
A product can have a price and optional: new_price. I would like to be able to sort them by price/new_price combined, meaning that I would need an additional entry in the DB like "final_price". I got an idea to create a non-editable field "new_price" in Content-Type Builder/schema.json and then update that with the final price for the product on "beforeCreate" in the lifecycles.js. However, I am not sure Strapi allows that, as I haven't been able to find a resource pointing in the documentation that it can. If there is a hacky way to do it, please advise. I am open to all kinds of other suggestions on how to do this Business logic as well.
Thank you in advance.
There is a way in strapi to make the field non editable on UI. You can go to Content-type-builder-> Your component-> Configure the view. And click on the text field. You can just make editable field as false.
I see two options:
(a) Add the field and forget about it being non-editable. You can calculate the final_price on insertion of an entry in your collection with Lifecycle hooks: https://docs.strapi.io/developer-docs/latest/development/backend-customization/models.html#lifecycle-hooks.
(b) Don't add a new field, but override the controller to return an additional field: https://docs.strapi.io/developer-docs/latest/development/backend-customization/controllers.html#extending-core-controllers.
Ok, so I found a "hacky" way to do this. I don't like it, as it is not that beautiful and sophisticated, but it does the job.
In product schema.json I added a
"final_price": {
"type": "decimal"
}
In lifecycles.js, I created a new function that will calculate my final price and write it in "final_price" attribute:
module.exports = {
beforeCreate(event) {
priceCalc(event);
},
beforeUpdate(event) {
priceCalc(event);
},
};
const priceCalc = (event) => {
const { data } = event.params;
data.final_price = data.new_price ? data.new_price : data.price;
};
In the admin panel, in Content-Type Builder in Product, I clicked "Configure the view" and deleted the Final Price field from Displayed Fields section. This made the field hidden, lol.
Now I am sorting all products with sort: ['final_price:asc']
That is it.Hope it helps anyone!

So I'm using Wix to create a ecommerce store, however the standard store isn't flexible enough for me.
I have a dynamic product page and I want to access product quantity in stock with code in order to show whether the product is in stock or not.
I fount this in the documentation (Link)
$w('#myProductPage').getProduct()
.then( (product) => {
let productName = product.name;
let productDescription = product.description;
// see example product object below
} )
.catch( (error) => {
console.log(error);
} );
The only thing is that I don't know whats the page name with what i have to replace '#myProductPage'.
As far as I understand it I have to replace it with my slug product page name however I don't know where I could see it - it should be named products-2 but that doesn't work, it shows an error that the name is not a valid selector.
I haven't found basically any example codes for Wix Corvid and that's why I'm reaaally struggling with such a small thing.
With $w(), you want to pass in the page element's ID -> $w('#elementID')
The element ID can be found in the property pane on the page. Select the page element, right click > View Properties. This will give you the ID you want to pass in to the function. Think of it like a document.getElementById() function replacement.
I have made a custom theme on big cartel, and everything is perfect, except one thing.
I would like to have the cart update without going to the cart page when adding an item to your cart.
I have made my custom template over the "sexy" theme and have no idea how I go about implanting this
I know this can be done, because default themes like "Good Vibes" do this.
You can use the code below. I didn't include the code for the restoreButton function in the addItem callback but I'm sure you get the idea. You'll also need your own means of retrieving the product ID based on however you're displaying your product options. Make sure to also include a reference to Big Cartel's javascript api.
$('#add_to_bag').click(function(evt){
var productId;
if($('.options_select').length != 0)
productId = $( ".options_select option:selected" ).attr('value');
else
productId = $('.price_options input').attr('value');
var quantity = $('.quantity input').attr('value');
Cart.addItem(productId, quantity, function(cart) {
$('#add_to_bag').attr('value', 'Item Added');
setTimeout(restoreButton, 2000);
});
});
You'll want to take advantage of the javascript API: https://help.bigcartel.com/developers/themes/#javascript-api
With this, you can drop in the line of code to load the API into your theme and have access to add, update, and remove items from the cart using javascript.

the above link is the simple example of Kendo grid with row template.All I wanted to do is make a specific column non-editable. the usual way is just define a model and further inside fields add editable False to the required field. i just wanted to know is there any other way to make a column editable as false because i dont want to add one more model in kendo as I am using models in entity level and Jay-data Level.
var dataSource = new kendo.data.DataSource({
data: records,
schema: {
model: {
id: "foo",
fields: {
foo: {type: "number"},
CostCategoryAbv: {type: "string",editable:false}, // i dont want this
VendorName: {type: "string"}
}
}
}
});
I've been doing a lot of work with the Kendo Grid using MVC. I've been getting around this by using a custom popup editor. The editor only allows the user to modify the fields that I want them to. Another way of getting around this is by changing the controller so that any user edit does not modify the field when the data source is updated. I know that the code provided is not using C# or MVC, but I hope this helps. I think you may be able to modify the save method so that it only saves select fields.
Is it possible to identify on a kendo UI grid which field was altered on a row edit?
Right now I am sending the entire row to the server that was changed. I would like to send
the request to the server to also include a variable holding the name
of the field that was edited.
Is something like that supported by kendo or
is there a work around for that?
This is not supported out of the box. However the grid API should allow this to be implemented. Check the edit and save events. In there you can listen to changes of the model instance which is currently being edit. Here is a quick example:
$("#grid").kendoGrid({
edit: function(e) {
e.model.unbind("change", model_change).bind("change", model_change);
}
});
function model_change(e) {
var model = this;
var field = e.field;
// store somewhere the field and model
}
I am sure there will be articles around this but I really don't know the correct name for it and having little success finding examples like mine.
I have a quote form where you have the ability to select a product and atributes of it. There are three dropdowns and based on the combination of the three, I have a table (with associated model/controller) that has a price. I want to display the price on the page but i must update as the selections are updated.
Setting the price from the get go seemed easy but then updating it based on dropdowns selected had me go in a tail spin of '"onSelectedIndexChanged()', javascript, AJAX, partial views and I simply confused myself.
I need a simple way to display price information on a quote form as they fill out the details (three fields control price). I did look at the music store demo but its slightly different and the shopping cart element which looked handy was grabbing data in a table so again got stuck.
Help always appreciated as ever.
Thanks,
Steve.
When one of the three dropdowns changes, I'd make an AJAX call to the server to get the price as a JSON object and use it to update the price input.
Example using jQuery to add the handlers and perform the AJAX operation.
var $priceControls = $('#control1,#control2,#control2');
$priceControls.change( function() {
$.getJSON( '#Url.Action("price","product")',
$priceControls.serialize(),
function(price) {
$('#price').val(price);
});
});
public class ProductController : Controller
{
public ActionResult Price( string control1, string control2, string control3 )
{
decimal price = ...lookup price based on control values...
return Json( price, JsonRequestBehavior.AllowGet );
}
}
