Datalynx Fields

Jump to: navigation, search

Note: You are currently viewing documentation for Moodle 2.7. Up-to-date documentation for the latest stable version of Moodle may be available here: Datalynx Fields.

Datalynx fields are used to collect and display predefined data elements such as text, dates or numbers in an entry. You can choose between a huge amount of fields. Field administration can be accessed via the tab "Manage -> Fields".

General field settings

These settings are available for all field types. For the settings of a specific field type have a look at the documentation of the specific field type.

Name

Name of the field. Will be used for creating the tag, that will be placed in a view. Example: Name = Car brands, the tag to place in view will be Car brands. Make the field name as short and simple as possible.

Description

Optional description of the field. Is not really used except in the fields overview in the "Manage" area.

Visible to

  • Everyone: Use this, if you want, that every course member (role with capability to access a view) can see the field. Example: Photo for a photo activity, that should be reviewed by other course members
  • Owners and managers: Use this, if you want to hide critical or personal informaation to be seen by other people than managers or the person who created the entry (= owner). Example: Hiding bank account numbers or other sensitive personal info.
  • Managers only: Use this to hide comments from the owner, such as evaluation comments, that should only be seen by other managers.

Editable

  • Yes: Owner and managers can edit
  • No: Only manager can edit the value (Example: Used for certification purposes)

Field label

The field label allows for specifying a designated field label that can be added to the view by means of the [[fieldname@]] field pattern. This field pattern observes the field visibility and is hidden if the field is set to be hidden. The field label can also serve as a field display template and it interprets patterns of that field if included in the label. For example, with a number field called Number and the field label defined as 'You have earned [[Number]] credits.' and an entry where the number value is 47 the pattern [[Number@]] would be displayed as 'You have earned 47 credits.'

Example

  • Field name: My number
  • Field label: <h1> My number is: [[My number]]. It is the best number of all! </h1>
  • Tag to be used in a view: [[My number@]]

Result in a view, that displays a chosen value: The tag [[My number@]] will be replaced with the field label and the field value, if the field is visible in a view. Assume you entered the number 40, then the result would look like this (it is a heading):

My number is: 40. It is the best number of all!

Result in a view, that is used for data input (creating an entry): Same as display, but instead of the number to display, the input field, where you have to enter the number will be displayed.

Adding a field

To add a field select the field type from the 'Add a field' dropdown. This will open the field configuration form where you can name the field instance and configure other settings as required.

Setting visibility

You can set the field visibility either in the field configuration form or by clicking the field's eye icon in the Visible column. The field can be visible to everyone (default), entry-author and managers, or only managers (where managers are users with manageentries capability in the context).

Setting editability

You can set the field editability either in the field configuration form or by clicking the field's lock icon in the Editable column. The field can be editable by the entry-author and managers (default) or only by managers (where managers are users with manageentries capability in the context).

Updating a field

You can click on the field's name or the edit icon of the field to open the configuration form for updating.

Duplicating one or more fields

You can duplicate a field by clicking the duplicate icon of the field. This will create an exact copy of the duplicated fiel with a different name. You can then proceed to update the field settings.

You can duplicate more than one field in one go by selecting the designated fields and clicking the bulk-duplicate icon (in the list's header).

Deleting one or more fields

You can delete a field by clicking the delete icon of the field. You can delete more than one field in one go by selecting the designated fields and clicking and bulk-delete icon (in the list's header).
