Re: Cake 3.0 - get source table and schema of each field in a recordset

Here's what i ended up with

class TableHelper extends Helper {

public function build(ResultSet $resultset)

{

foreach ($resultset as $result) {

$schema = $this->getSchema($result->source(), $result->toArray());

break;

}

debug($schema);

//do stuff

}

public function getSchema($table, $data)

{

$schema = [];

foreach ($data as $field => $value) {

if (is_array($value)) {

$schema[$field] = $this->getSchema($field, $value);

} else {

$schema[$field] = TableRegistry::get($table)->schema()->columnType($field);

}

}

return $schema;

}

}

here's the result

[  	'id' => 'integer',  	'name' => 'string',  	'group_id' => 'integer',  	'sconto' => 'decimal',  	'bilancio' => 'decimal',  	'groups' => [

		'id' => 'integer'
		'name' => 'string'  	]  ]

i'm looking to load the whole schema for each field, how can i do? i still haven't found a way.

Looking forward for your advices/enhanchments :)

Ok i'll try.

i'll let you know

Thank you very much

Associations are already loaded, as you define them in the initialize() method of the table.

You can inspect the associations tree in a query by calling $query->eagerLoader()->normalized($query->repository());

The "inspect the contain tree" way sounds better.

i'll try to explain:

With your method you will end up loading every belongsTo and hasOne association, even if not used.

The table i'm using right now has 3 belongsTo relationships but i need to show only one

On the second hand: first level association are not always enough.

This worsen the problem quite a bit.

if i use your method i must recursively loop throug tables and theyr relationships, loading a ton of useless classes.

What do you think?

The associations used in a find are represented in a Tree-like structure. I guess in your case it will be more than enough getting the first-level associations

of type belongsTo and hasOne, as those are the only types that can be represented in a html table (they are in the same level of nesting)

So to get associations of a table of type belongsTo and hasOne:

$firstLevelAssociations = 

collection($mainTable->associations()->type('HasOne'))

    ->append($mainTable->associations()->type('BelongsTo'));

$schemas = [];

foreach ($firstLevelAssociations as $association) {

   $schemas[$association->property()] = $association->schema();

}

At the end of the loop you will have an array of property names pointing to the table schema. So, finally:

foreach ($schemas as $property => $schema) {

   if ($singleResultFromQuery->has($property)) {

        // Do stuff with the schema

   }

}

This is one way to do it. The other way is inspecting the query object to get the 'contain' tree. Let me know if you need to know more about it :)

what about getting all the associations used in a record set?

Usually all records in a result set are of the same table, so you on;y need to do that for the first result.

If you have associations, then you can get the property in the result:

$associationSource = $result->association_property->source();

Hi all

i'm migrating an HtmlTableHelper from a Cake 2.x project to  new 3.0 one

The main function of this helper scans the array of data passed as argument and uses ClassRegistry to obtain schemas for each Model.field.

Later on these informations are used to format the TDs (text fields justified to the left, number fields justified to the right and so on).

in 3.0 data arrays are gone, replaced by resultsets.

I tried to rewrite a similar approach but i'm struggling with Cake's new ORM

what's the best way to get source table and schema of each field in a recordset?

Thank you very much
