Database presets

There is one default preset, Image Gallery. It is possible to create your own presets.

When you have created your database that you desire to set as a preset; go to the "Presets" tab of the database and choose "Save as preset". Give the preset a name and the database fields and templates will now be available as a preset for the rest of the site. You will need site admin rights to do this.

Please see the Database presets for other available presets you can import into your system.

¿Cómo puedo crear una BasedeDatos en la cual los estudiantes solamente puedan ver sus propias entradas?

Either:

  • Set up the database so that entries require approval. If the entries are never approved, then only the student that added a particular entry and the teachers can view it.

Or:

  • Set the group mode of the database to "Separate groups" and assign each student to a separate group.

Or:

  • Set the maximum number of entries to exactly how many are required of the student then set the entries required before viewing to several more than that number. The students will be able to post up to the number of posts for the assignment but not get to the number needed for viewing.

How can I enable a sort function by clicking on the field headings?

For sorting, you need to manually create the link in the template around that heading. To find the URL you need, you can do a sort using the menus and then look in the URLs. Take out everything but the d, sort and order parameters. For example,

http://moodle.org/mod/data/view.php?d=13&sort=44&order=ASC

http://moodle.org/mod/data/view.php?d=13&sort=44&order=DESC

How can I add highlighting like on the Module and plugins page?

In the repeated part of the template (note onmouseover and onmouseout to change the classes):

<tr onmouseover="this.className='trhighlight'" onmouseout="this.className='trnormal'">
 <td class="c0"><b><a href="##MoreURL##">[[Name]]</a></b></td>
 <td class="c1">[[Type]]</td>
 <td class="c2">[[Requirement]]</td>
 <td class="c3">[[Status]]</td>
 <td class="c4">[[Summary]]</td>
 <td align="center" class="c5">##Edit## ##Delete## ##More## ##Approve## </td>
</tr>

In the CSS template there are two styles:

.trnormal td {
   background-color: #FFFFFF;
 }
 .trhighlight td {
   background-color: #EEEEEE;
 }

How can I make email addresses clickable?

To make email addresses clickable, add the following code to the single template:

How can I hide a database entry which was previously approved?

There is currently no user interface for hiding a database entry which was previously approved i.e. setting it to require approval again. However, an entry can be hidden using MySQL Admin by editing it in the data_records table and changing the approved value from 1 to 0.

How can I add a default sort order of entries?

In the Fields tab, select a default sort field, choose ascending or descending then click the Save button.

Why is my database so slow to show each page?

Try to go to "Administration > Miscellaneous > XMLDB editor" and choose "Check Indexes". If you have any missing indexes found; upgrade your Moodle to the latest weekly build of your version; re-run the test; backup your site database and then run the suggested SQL from the test on your site database. This should speed up your database activity load times.

How can I prevent students from adding entries?

An override may be used to close/archive a database activity, or have a database in which only teachers can add entries, but students can view the entries.

  1. Follow the Permissions link in the settings block under Database activity administration
  2. Remove Student from the capability mod/data:writeentry by clicking the 'X' next to it.
  3. Click the continue button to confirm.

How can I empty a database / remove records from a database en masse?

I get an error message when importing a csv of entries

One thing to try is to open up the csv file in Excel and save it again as a csv file - with another name - and then try importing it agin. Sometimes this just works :)

How do I export/import picture fields from a database activity from one course to another?

You cannot export/import database entries with picture fields using the csv option, you will need to use Moodle's backup and restore functionality. Please note that you will need to backup and restore the database activity with user data in order for the entries to be carried over.

How can I show recently added entries in a block on the course page?

  1. Enable an RSS feed of recently added entries as described in Usando BasedeDatos
