When using themes you want to changes some of the translations specifically to the theme while keeping the standard translations for most of the text.
Duplicating the main translation file is a headache for maintainance.
This how to provides a solution.
To secure your database from inconsistencies resulting from failing (complex) operations, you (should) use transactions.
However, complex methods often rely on other complex methods that themselves build on transactions.
This HowTo presents a method to nest or embed transactions without relying on the database's nesting capabilities.
I have two tables called hospitals and departments. I have a junction table between them which holds the departments in each hospital. But sometimes I need a list of "All hospitals with All possible departments" - regardless of whether they are linked in the junction table or not.
It is difficult to perform user dependent theming through a general configuration in 'main.php'.
This article proposes a method to do so through a Factory that dynamically generates classes to allow delayed resolution of actual user values.
This means that you can refer to values that are stored in the database through the CActiveRecord before Yii is actually loaded.
The values will be fetched from the database when actually used for the first time, which is after Yii is loaded.
Actually, you can use pretty much any method that relies on Yii with this method.
There is an issue on Yii2 to redirecting / urls to /frontend/web.
In other words we need a way to hidden /frontend/web from addresses.
We will do this without changing Apache configuration and creating virtual host or setting document root (It's good for share hostings that we have not access to apache.conf)
This Behaviour helps to view time/date/timestamp/datetime from db to local Date / Time / Date Time format and in local Timezone. And save into db in with db timezone and db format. You only need to include this behaviour in models where need this facility.
