You may face with the situation when it is necessary to change a data grid for your OroCRM application. It is quite easy if you have already created your own bundle (we’ve described how to create a bundle in the previous article).
In this case, you can simply add few changes to datagrid.yml of this bundle. Nevertheless, sometimes we have to work with the bundles created by other developers or system bundles. And in those cases, we can use two ways: overwrite a full data grid configuration of the corresponded bundle or work with events of a listener.

As you may know, to add new data to Symfony bundles we can use migration scripts or it is also possible to use a fixture for this. However, we do not recommend to use the fixture if you need to change some configurations, alter table or insert any specific variable. Fortunately, OroCRM team has provided the solution for SQL queries in the migration scripts – we can use Insert, Update, Delete and other queries there.

Sometimes we can face with the different dependencies between the system bundles or bundles that are already created by other developers, and we will have to change the configuration for such bundles. Usually, it can be easily done because OroCRM has a quite good GUI interface. So, using GUI you will be able to change the configuration for any bundle. Nevertheless, pay attention that if you need the bundle for deployment to different servers, this way is not convenient. In case of deployment, you will need to add a description of the appropriate settings and it is also important to follow these settings in further development. The best way is to use the migrations scripts. In this article, we will show you how to change a config of a single entity in the bundle.

If you have ever developed the bundles for OroCRM, you should know that there is a need to add a button to different places. OroCRM developers can find many ways of adding different types of buttons on the pages. And our article will describe the general button’s types.

Every OroCRM developer can face with a situation when there is a necessity to change a configuration for the entity config in the bundle. And it is no problem if we have an ability to remove a full bundle with the database tables. Recently, we’ve tried to change the ownership scope for the existing entity, but we could not delete the tables because there were a lot of data.

We’ve prepared step by step guide about how to install OroCRM on Maс. We are highlighting problems that you may face with during an installation process.
