Class

Clownfish - class (data structure)

In the Clownfish backend you can define your datamodel by creating classes (do not mismatch with classes of OOP). For example you can model a datamodel called User. Go to the class page and enter the name User in the input field, check the Search engine relevant checkbox (if content of this class should be indexed by Lucene) and click the New button. A new entry in the class list will appear. Select this entry and define the fields for the new class.

Add the fields like this:

1. Fill the field name
2. Select the type of the field
3. Check the identity flag (only when the class should save unique values for this field)
4. Check the autoinc flag (only when the field is an integer and a new content entry should automatically increment this value)
5. Click the New button

Assuming you want to create a similar class like this:

attribute	description
id	unique id with autoincrement
name	user name
email	user email
password	user password encrypted
birthday	user birthday

• Create a field named id with type integer and identity flag and autoinc flag both checked.
• Create a field named name with type string and leave the flags unchecked.
• Create a field named email with type string and identity flag checked (email must be unique in this case).
• Create a field named password with type hashstring and leave the flags unchecked. The password will be encrypted in the database.
• Create a field named birthday with type datetime and leave the flags unchecked.

Datatypes

You can use the following datatypes for fields:

type	description
boolean	true or false
datetime	timestamp
hashstring	encrypted string for storing passwords
htmltext	text for HTML content
integer	integer values
media	special link to internal assets
real	floatingpoint values
string	string values 255 chars
text	text not HTML interpreted
markdown	text Markdown interpreted
classref	reference to another class
assetref	reference to an assetlibrary
