Tiki CMS is a powerful tool that contains multiple functionalities, among which it allows the creation of a full stack application without programming skills.

You know that often a full stack application is composed of the front-end and the back-end. The front-end is everything the user sees, and the back-end is the storage (the database) and a language that manages this storage logic, in a nutshell.

In Tiki CMS, we also have trackers that can be considered as the database, and everything you can do with a normal database, well, you can also do with the trackers in Tiki CMS. We can also create linked tables (Entity Relationship).

You can read more about the Tiki CMS trackers here Trackers

Before creating an application that requires a database, we first start by drawing the different tables to see how the different data storage tables will be linked to each other. Sometimes, to better understand an already existing application, we have to resort to this drawing or the database to see how the tables are linked to each other.

There are several types of diagrams that allow modeling an application, but among them we have the entity-relationship diagram (ERD), which is what interests us here.

We have added a feature that allows us to directly show how the trackers are linked to each other. This was done thanks to the Mermaid library, which is open source (Mermaid).

Right buttons

This section consists of 3 buttons.

• The first button shows the default view, where we directly see the diagram.

• If we check the second button, we will see our diagram in Mermaid format. The text shown in Mermaid format can be transferred to other tools that support Mermaid format, and your diagram will be displayed there as well. For example, you can transfer it to this site mermaid live editor, and you will see your diagram in their tools. This button allows the transfer of ER diagrams without much effort. This format can be exported; just click on the export button, and the file will be downloaded to your device.

• The third button allows you to export your diagram in SVG format. This format can be exported; just click on the export button, and a file will be downloaded to your computer.

Sometimes, when you want to start using this feature in Tiki CMS, you might find yourself not seeing the diagram but getting a raw format for every different view.

This happens because your server does not yet support the mjs file.

Example: Assuming you are using MAMP, in that case, you must find the httpd.conf file and add a line to make your server understand the mjs file.

Go to MAMP directory > conf > apache > httpd.conf file and add this line:

AddType application/javascript .mjs
