Updated 3 years ago by BoazTips0 comments – viewed 23,780 times – ( +5 / -1 ) – version 1.1
When you're filling up a form of a CActiveRecord (using CActiveForm for example), usually you'll construct your code so that in case of validation error you'll get back the form with the error displayed back to you, typically when CActiveForm.errorSummary() is used. This is how its done by Gii.

Auto-update denormalized attributes with MongoDb and Yii2

Updated 3 years ago by CeBeTips0 comments – viewed 9,580 times – ( +1 / -1 ) – version 2.0
You have different collections in MongoDb with de-normalized attributes. As you may know, due to its not-join nature, MongoDb tends to encourage repetition of the same value in different collections (de-normalization). In this MongoDb is opposed to a more SQL-like approach where you usually reference only the ID of the value with a foreign key.

There are situations in which Active Record will generate nonsense queries from what a nieve Yii user might think is reasonable code. One such situation is a CActiveDataProvider using CDbCriteria to get data from parent and 1:n child table with a condition on the child table.

Adding a date range search for CGridView the easy way

Updated 3 years ago by mikewalenTips6 comments – viewed 32,651 times – ( +12 / -2 ) – version 1.1
After a lot of research, everything I found on adding date range searching to a CGridView advanced search form seemed to involve adding two new public variables (e.g. $date_from, $date_to), 'safe' rules for the new variables, and a rather chunky if/elseif/else check in the search() method. This probably isn't a hassle for most, but because many of the tables in my database contain two or three and sometimes four date columns (e.g. date_created, date_modified, date_deleted etc.), it meant I was having to add up to eight public variables, the corresponding safe rules, and modifying the search() criteria for each date attribute. So, I set about creating a better way and I thought I'd share my work with the community.
