Error With Parsing $_Post Data In Controller, And Rendering Cgridview - php

Question

i'm facing a problem passing the correct value to the grid widget in the view. The data is being passed from jquery using ajax.
Here is the code::
$('#find-product').click(function(e) {
e.preventDefault();
alert($('#find-product').data("url"));
/*
* Make the ajax call to send the selected option to the controller for processing
* URL : $('#find-product').data("url") , the path of the controller's action
* Dropdown : the obejct that is passed to the controller
*
* Dropdown.category : the category selected
* Dropdown.price : the price range selected
*
*
*/
$.ajax({
url: $('#find-product').data("url"),
data: {
Dropdown: {
category: $('#supp-category').find(":selected").text(),
price: $('#supp-price').find(":selected").text()
}
},
type: "POST",
error: function(xhr, tStatus, e) {
if (!xhr) {
alert(" We have an error ");
alert(tStatus + " " + e.message);
} else {
alert("else: " + e.message); // the great unknown
}
},
success: function(resp) {
document.location.href = $('#find-product').data("url");
}
})
});
So i want to send the object named Dropdown to the controller action. In this case its /products/dropdown.
In the actionDropdown() i'm trying to form a CDbCriteria and passing it to CActiveDataProvider so that i may use it to render the grid.
Here is the code for the actionDropdown in the ProductsController ::
public function actionDropdown() {
$criteria = new CDbCriteria;
$criteria->compare('category', $_POST['Dropdown']['category'], true);
$dataProvider = new CActiveDataProvider('Products', array(
'criteria' => $criteria,
));
$this->render('selectproducts', array(
'dataProvider' => $dataProvider,
));
}
And here is the view, called selectproducts.
<div class="row">
<?php
$this->widget('bootstrap.widgets.TbGridView', array(
'id' => 'products-grid',
'dataProvider' => $dataProvider,
'filter' => $dataProvider,
'columns' => array(
'id',
'name',
'category',
'brand',
'weight_unit',
'price_unit',
'flavors',
'providers',
),
));
?>
</div>
Now this is giving me an CException error. Here is the error stack trace::
CException

I cannot for the life of me figure out what is causing this error. Please provide any sort of help, any tip that will head me in the right direction.
Thanks, in advance.

Answer 1

The problem is with filter param in TbGridView. Filter must be instance of your model, not dataprovider.
$this->widget('bootstrap.widgets.TbGridView', array(
'id' => 'products-grid',
'dataProvider' => $dataProvider,
'filter' => $dataProvider->model, // Simplest way
'columns' => array(
'id',
'name',
'category',
'brand',
'weight_unit',
'price_unit',
'flavors',
'providers',
),
));
Or just assign YourModel::model() as your filter param.
