I have an array of models that looks something like this. The models are extensions of the base Yii model class (BazClass), so that's a little bit of a custom solution, but I don't see why it shouldn't work.
$list = array
(
0 => FooClass#1
(
[BazClass:_attributes] => array
(
'FOO_ATTRIBUTE' => '4567'
'BAZ_ATTRIBUTE' => '1234'
'NAME' => 'FOO BAR'
)
[BazClass:_related] => array()
[_md] => null
[CModel:_errors] => array()
[CModel:_validators] => null
[CModel:_scenario] => ''
[CComponent:_e] => null
[CComponent:_m] => null
),
)
I made this a data provider by doing so:
$dataProvider = new CArrayDataProvider($list, array(
'pagination'=>array(
'pageSize'=>10,
),
));
$dataProvider->setData($list);
And try to render it in the view like so. Basically I'm just trying to show a list of the names, with the column named "Name".
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
array(
'header' => 'Name',
'value' => $data->NAME,
),
),
));
The examples in the CGridView documentation make it look like that is possible, but the error I get is:
Either "name" or "value" must be specified for CDataColumn.
Well, I did specify a value, obviously, but it seems to be null. I also tried $data['NAME'] (because I somewhere read that the CArrayDataProvider doesn't return models), but it still evaluates to null.
I also checked that $dataProvider->getData() returns the same list as I passed it.
What gives?
you should place quotes around your value otherwise it gets interpreted in the wrong context
array( 'header' => 'Name', 'value' => '$data->NAME', ),

I am trying to use the TbEditableColumn and the type select to have a pulldown menu.
The pulldown menu I need is filled by a function that I call.
That is working for basic cases. But for a another column, the pulldown values are dependent from the row in which it is (grid-view).
So for example the function I want to call to fill the pulldown and pass the id of the current data is:
$model->getPulldownValues($data->id)
But that throws an error that the variable $data is not defined. The funny part is that outside the editable array, I can use $data as expected.
See example below:
Any ideas?
$this->widget('bootstrap.widgets.TbExtendedGridView', array(
'type' => 'striped bordered',
'id'=>'order-image-grid',
'dataProvider'=>$model->search(),
'ajaxUpdate'=>true,
'template' => "{items}\n{extendedSummary}",
'rowCssClassExpression'=>'"FMDBGridColumn".$data->order_error',
'columns'=>array(
array(
'class' => 'bootstrap.widgets.TbEditableColumn',
'name' => 'streets',
'htmlOptions'=>array('width'=>'150'),
'value' => 'CHtml::value($data, "street")',
'editable' => array(
'type' => 'select',
'source' => CHtml::listData($model->availableStreets($data->id), 'id', 'street'),
'url' => $this->createUrl('cities/editable'),
'placement' => 'right',
)
),
),
));
Try to change method "availableStreets" into getter, e.g.:
public function getAvailableStreets()
{
// we don't need to send id as parameter of method,
// we can get it directly from model
// e.g.: $id = $this->id;
//
// put your code here
}
then, in widget, use property
$model->availableStreets
instead of method
$model->availableStreets($id)
Also you can put
CHtml::listData() into your getter and use
'source' => 'availableStreets',
instead of
'source' => CHtml::listData($model->availableStreets($data->id), 'id', 'street'),
you have to consider that $data in 'value' => 'CHtml::value($data, "street")', is referring to a model object which $model->search() is providing, but $data outside of the grid is different(You haven't shared what that is).
I have a CakePHP model, let's call it Thing which has an associated model called ItemView. ItemView represents one page view of the Thing item. I want to display how many times Thing has been viewed, so I do the following in my view:
<?php echo count($thing['ItemView']); ?>
This works, however as time goes on the result set of this query is going to get huge, as it's currently being returned like so:
array(
'Thing' => array(
'id' => '1',
'thing' => 'something'
),
'ItemView' => array(
(int) 0 => array(
'id' => '1',
'thing_id' => 1,
'created' => '2013-09-21 19:25:39',
'ip_address' => '127.0.0.1'
),
(int) 1 => array(
'id' => '1',
'thing_id' => 1,
'created' => '2013-09-21 19:25:41',
'ip_address' => '127.0.0.1'
),
// etc...
)
)
How can I adapt the model find() to retrieve something like so:
array(
'Thing' => array(
'id' => '1',
'thing' => 'something',
'views' => 2
)
)
without loading the entire ItemView relation into memory?
Thanks!
So it's pretty straight forward, we can make use of countercache - Cake does the counting for you whenever a record is added into/deleted fromItemView:
Nothing to change in your Thing.php model
Add a new INT column views in your things table.
In your ItemView.php model, add counterCache like this:
public $belongsTo = array(
'Thing' => array(
'counterCache' => 'views'
)
);
Then next time when you do addition/deletion via ItemView, Cake will automatically recalculate the counting and cache into views for you, so the next time when you do the query, you also need to make sure you specify recursive = -1 as what #Paco Car has suggested in his answer:
$this->Thing->recursive = -1;
$this->Thing->find(...); //this will returns array of Thing + the field "views"
// --- OR ---
$this->Thing->find(array(
'conditions' => array(
//... your usual conditions here
),
//... fields, order... etc
//this will make sure the recursive applies to this call, once only.
'recursive' => -1
);
The following query returns an array containing the proper ids, but null for all values.
If I remove the aggregation function (AVG()), it returns values (not the averaged ones of course), if I choose e.g. find('all') it returns the average, but not in the list format I want (I could work with that, but I want to try to do it with 'list' first).
$progress = $this->Trial->find('list', array(
'fields' => array(
'Trial.session_id',
'AVG(Trial.first_reaction_time_since_probe_shown) AS average_reaction_time'
),
'group' => 'Trial.session_id',
'conditions' => array(
'Trial.first_valid_response = Trial.probe_on_top',
'TrainingSession.user_id IS NOT NULL'
),
'contain' => array(
'TrainingSession' => array(
'conditions' => array(
'TrainingSession.user_id' => $this->Auth->user('id')
)
)
),
'recursive' => 1,
));
The generated SQL query returns exactly the result I want, when I send it to the DB via PhpMyAdmin.
SELECT
`Trial`.`session_id`,
AVG(`Trial`.`first_reaction_time_since_probe_shown`) AS average_reaction_time
FROM
`zwang`.`trials` AS `Trial`
LEFT JOIN
`zwang`.`training_sessions` AS `TrainingSession` ON (
`Trial`.`session_id` = `TrainingSession`.`id` AND
`TrainingSession`.`user_id` = 1
)
WHERE
`Trial`.`first_valid_response` = `Trial`.`probe_on_top`
GROUP BY
`Trial`.`session_id`
I've examined the source for find('list'). I think it's due to the "array path" for accessing the list getting screwed up when using functions in the query, but I couldn't fix it yet (or recognise my abuse of CakePHP logic).
Once I posted the question, Stackoverflow started relating the correct answers to me.
Apparently, it can't be done with 'list' without virtualFields.
I didn't expect that because it worked using the other find-types.
$this->Trial->virtualFields = array(
'average_reaction_time' => 'AVG(Trial.first_reaction_time_since_probe_shown)'
);
$progress = $this->Trial->find('list', array(
'fields' => array('Trial.session_id','average_reaction_time')
/* etc... */
));
I have a model template which hasmany themes.I want to show the list of templates with count of themes.I am using this
$this->Template->bindModel(
array(
'hasMany' => array(
'TemplateTheme' => array(
'className' => 'TemplateTheme',
'fields' => 'count(TemplateTheme.id) AS themes'
)
)
), false ...
it gives me 2 templates.But it gives me all the 3 themes count in the first template whereas 2 themes belongs to template 1 and the third theme belongs to template 2
in the query it is using id IN(template_id1,template_id2)
Any idea how to do this?
You are doing a common mistake, you are counting everyrow each time since you are not using group by, you should do is group by Template.id when you do your search. Butttttttt.... has many wont do a join :( so you have to force it a littleor use something like linkable component
example
$join = array(
array('table' => 'templateThemes',
'alias' => 'TemplateTheme',
'type' => 'LEFT',
'conditions' => array(
'Template.id = TemplateTheme.Template_id',
)
)
);
$fields = array('Template.id','count(TemplateTheme.id) AS themes');
$this->Template->find('all', array('fields'=>$fields, 'joins'=>$join', $group =>array('Template.id')));
You may also do it in reverse since belongsTo does the join something like this
in your model (it is always recommended to put it static in your model unless is not a normal association)
var belongsTo = array(
'Template'=> array(
'classname' => 'Template',
'foreign_key' => 'template_id'
);
and in controller
$fields = array('Template.id','count(TemplateTheme.id) AS themes');
$this->Template->find('all', array('fields'=>$fields, $group =>array('Template.id')));
Hope this helps you, if not just comment
I have a table that's been created by a module. I need to include some of its fields into an existing view.
I tried using the table wizard module, but all it does is create a separate view for that table. I'd like to be able to choose fields from that table to be added into an existing view as additional fields, or through relationships or something like that. Is there a workaround to do what I'm trying to do?
Ah. Views. Took me a while as well. This answer is for Drupal 6 and in the abstract shows how to define fields as well as using a relationship to allow the fields to link to the node table.
Inside modulename.module, you want a function that goes:
function modulename_views_api() {
return array(
'api' => 2,
);
}
Then you want to make a file called modulename.views.inc and define a function like this:
function modulename_views_data() {
$data['modulename_table'] = array(
'table' => array(
'group' => 'ModuleName',
'title' => 'Module name title',
),
'join' => array(
// to join to node, we'll use a field in modulename_table called 'nid'
'node' => array(
'left_field' => 'nid',
'field' => 'nid',
),
),
);
// now we define the fields in the table like this
// check out modules/views/handlers to see more specific handlers
$data['modulename_table']['fieldname'] = array(
'title' => 'fieldname',
'help' => 'fieldname description',
'field' => array(
'handler' => 'views_handler_field',
),
);
$data['modulename_table']['nid'] = array(
'title' => 'related node',
'help' => 'the field that relates back to {node}',
// here we implement a relationship to nid
'relationship' => array(
'base' => 'node',
'field' => 'nid',
'handler' => 'views_handler_relationship',
'label' => 'modulename row node',
),
// this relationship can be turned on in views
);
return $data;
}
You can use hook_views_data to define your table in code. As long as you don't want views to do special manipulations, it's almost as simple as defining the table with the schema API.
Your other option is to use table wizard to expose the tables to the database and then use the migrate module to create the views. http://drupal.org/project/migrate
I have found that the Views Custom Field module lets me do just about anything I need as far as adding oddball fields to views .. maybe it'd help ..
