# Dec 28th 2018, 13:07 G00DSP33D in terms of performance we're really happy with this light approach we have now, but we just want to switch to 3.x for all the other cool stuff. And check how we can query against those dynamic fields.
# Dec 28th 2018, 13:06 admad you'll have to explicitly set the type to json in table schema
# Dec 28th 2018, 13:06 G00DSP33D yes indeed, that's why we try to avoid a full EAV setup
# Dec 28th 2018, 13:05 admad using json field for variable content fields/blobs is fine, EAV can be overkill
# Dec 28th 2018, 13:05 G00DSP33D also true
# Dec 28th 2018, 13:04 challgren Nah you dont need all the extra controllers and views
# Dec 28th 2018, 13:04 G00DSP33D We did that in the past, but required to set up extra controllers, models, views, etc., next to all the extra SQL work. Right now in order to add a new field, we just add a new element to an array and it's done.
# Dec 28th 2018, 13:03 challgren base_table -> attribute_table
# Dec 28th 2018, 13:03 challgren Or have associated tables
# Dec 28th 2018, 13:03 G00DSP33D That's why we try to keep it dynamic.
# Dec 28th 2018, 13:03 G00DSP33D The problem is that we don't want to go crazy wide with columns in our Pages table
# Dec 28th 2018, 13:03 challgren Have you looked into https://book.cakephp.org/3.0/en/orm/query-builder.html
# Dec 28th 2018, 13:02 admad replacement for notEmpty are specific `allowEmpty*` functions https://github.com/cakephp/bake/pull/486
# Dec 28th 2018, 13:02 challgren You'll need the typemap
# Dec 28th 2018, 13:02 G00DSP33D We also know that MySQL now supports true JSON fields, so we're also looking into getting those to work with CakePHP.
# Dec 28th 2018, 13:02 challgren I personally would suggest just storing those dynamic fields non-dynamic and then changing the validation set based on the product type
# Dec 28th 2018, 13:02 admad There is no replacement $hasRendered. In 4.x you can simply call render() multiple times
# Dec 28th 2018, 13:01 G00DSP33D Yes, fully agree, awesome features in there!
# Dec 28th 2018, 13:00 G00DSP33D But thanks for the suggestion you gave, that could already help us with the validation part.
# Dec 28th 2018, 13:00 challgren It takes a bit but once you understand it, its a much better platform than 2.x
# Dec 28th 2018, 13:00 G00DSP33D We're also still wrapping our heads around this migration
# Dec 28th 2018, 13:00 challgren Im kind of in the same boat converting from 2.10 to 3.6-7
# Dec 28th 2018, 13:00 G00DSP33D Haha, understand you completely challgren
# Dec 28th 2018, 12:59 challgren Granted I'm a 3.x newbie (Kind of in the same boat you are) but not that Im aware of but someone else may have more knowledge on that
# Dec 28th 2018, 12:59 G00DSP33D Now in 2.x we have to use REGEX to get that done, which is off course horrendous work and extremely slow.
# Dec 28th 2018, 12:58 G00DSP33D Our second question is whether CakePHP 3.x now offers any way to query against serialized data using complex data types. If "price" is serialized into a JSON string, can we now for example sort our product pages by price? Or query to select pages with a certain minimum price?
# Dec 28th 2018, 12:57 G00DSP33D Aha thanks <slackebot>, that looks interesting.
# Dec 28th 2018, 12:56 G00DSP33D So we were happy to learn that support for comp[lex data types has been added in 3.x. But we're wondering whether there are now more intelligent way stop do what we are doing in terms of validation.
# Dec 28th 2018, 12:56 challgren https://book.cakephp.org/3.0/en/orm/validation.html#using-a-different-validation-set
# Dec 28th 2018, 12:56 challgren You can use different validation sets
# Dec 28th 2018, 12:55 G00DSP33D So we dynamically add those validation rules in the beforeValidate. This allowed us to validate field values that are serialized into JSON later on.
# Dec 28th 2018, 12:54 G00DSP33D Our approach: in beforeValidate we check the contents of the field Page.type. Let's say that it contains "product_page". In a CakePHP Config we kept a list of "dynamic fields" per page type, and their respective validation rules.
# Dec 28th 2018, 12:53 challgren If you want tha ability to sort or filter
# Dec 28th 2018, 12:52 challgren You may need to define those fields even if they are unnecessary for every record
# Dec 28th 2018, 12:51 challgren I run an app that integrates with QBO but I dont store dynamic data in JSON
# Dec 28th 2018, 12:51 G00DSP33D For example, our light approach doesn't allow us to sort products by price for example (unless we jump through a lot of hoops).
# Dec 28th 2018, 12:51 challgren You could define a custom validation rule but Im not very familiar with it
# Dec 28th 2018, 12:50 G00DSP33D Since we are now upgrading to 3.x, we're left wondering whether there are better ways to handle this light "Entity-Atribute-Value" setup.
# Dec 28th 2018, 12:49 G00DSP33D So in CakePHP 2.x we used a TEXT field in the DB to store these "dynamic" properties. Depending on the page type, we dynamically added validation rules inthe beforeValidate callback.
# Dec 28th 2018, 12:48 G00DSP33D Our CMS has a simplified take on the EAV pattern for storing dynamic data about webpage. A product page will have different data fields (price, weight, etc.) compared to a blog post (intro txt, etc.).
# Dec 28th 2018, 12:47 challgren Like how so?
